Science Explains How Goji Berries Can Preserve Eyesight

A new study by University of California Davis researchers reveals that dried goji berries could help age-related vision loss. Frequent consumption of the berries could prevent or slow the development of age-related macular degeneration, or AMD.

In older people, AMD causes more vision loss than any other condition. It’s the third leading cause of blindness globally, affecting over 11 million adults in the US and 170 million worldwide.

“AMD affects your central field of vision and can affect your ability to read or recognize faces,” said Glenn Yiu, a study co-author and an associate professor in the Department of Ophthalmology and Vision Sciences.

Study Proves That Dried Goji Berries May Reduce Age-Related Vision Loss

vision loss

Researchers conducted a small, randomized trial with 13 healthy middle-aged participants (aged 45 to 65) at UC Davis. The volunteers ate 28 grams (about a handful) of goji berries five times weekly for 90 days.

After the study period, the density of protective pigments such as lutein and zeaxanthin in their eyes significantly increased. These pigments filter out dangerous blue light and boost antioxidant production. Both of these pigments help protect against age-related vision loss.

“Lutein and zeaxanthin are like sunscreen for your eyes,” said lead author Xiang Li, a doctoral candidate in the Nutritional Biology Program.

“The higher the lutein and zeaxanthin in your retina, the more protection you have. Our study found that even in normal healthy eyes, these optical pigments can be increased with a small daily serving of goji berries,” said Li.

On the other hand, 14 participants who consumed an eye health supplement over the same period didn’t see any improvement.  The study results have been published in the journal Nutrients.

Goji Berries Used in Traditional Chinese Medicine

Goji berries grow on two species of shrub bushes native to northwest China: Lycium chinense and Lycium barbarum. They have a sweet, slightly sour taste and have been used in Chinese medicine for thousands of years. They’re a key component of many Chinese soups and herbal teas and are often eaten as a snack.

According to Chinese medicine, goji berries have “eye brightening” qualities, which help slow age-related vision loss. Since Li grew up in northern China, she wanted to investigate how the powerful berries impacted eye health.

“Many types of eye diseases exist, so it is not clear which disease ‘eye brightening’ is targeting,” said Li.

First, she researched the bioactive compounds in goji berries and found they possessed high lutein and zeaxanthin levels. These powerful antioxidants help reduce the risk of age-related vision loss such as AMD.

Li also discovered that goji berries contain a highly bioavailable form of zeaxanthin. This means that the digestive system can easily absorb it so the body can utilize it.

Causes and Treatment for Age-Related Vision Loss, Like Macular Degeneration

Currently, treatment for moderate cases of AMD calls for specialized dietary supplements called AREDS. These contain vitamins C, E, zinc, copper, lutein, and zeaxanthin. Currently, no therapy specifically targets macular degeneration in its earliest stages. IT CAN BE DIFFICULT TO DIAGNOSE because AMD doesn’t present with symptoms at first. However, doctors can detect it and other eye issues during a regular eye check-up.

According to Yiu, many complex factors contribute to the development of age-related vision loss. These include genetic vulnerability, age-related changes, and lifestyle factors like smoking, diet, and sun exposure.

“Our study shows goji berries, which are a natural food source, can improve macular pigments of healthy participants beyond taking high-dose nutritional supplements,” said Yiu. “The next step for our research will be to examine goji berries in patients with early-stage AMD.”

The authors note that while the results are encouraging, more studies are needed to confirm the results.

However, one other study in 114 people with early macular degeneration showed improvements with goji berry supplements. They took a daily supplement for 90 days and showed greater macular pigment density, slowing AMD’s progression.

Other Ways to Slow or Prevent Age-Related Vision Loss

If you want healthier eyes, follow these tips from the National Institute on Aging:

  • Wear sunglasses and a wide-brimmed hat when you’re outdoors in the sun. Even on cloudy or winter days, the sun can still damage your eyes, so protect them year-round.
  • Quit smoking, as it can increase the risk of age-related vision loss and diseases like AMD or cataracts.
  • Maintain a healthy diet full of fresh fruits and vegetables. Goji berries, blueberries, carrots, leafy green vegetables, nuts, seeds, eggs, and salmon have high antioxidant levels and fatty acids that promote eye health.
  • Get regular exercise and lose weight if needed.
  • Manage blood pressure and diabetes (if you have it), as both conditions can contribute to age-related vision loss.
  • Take breaks every twenty minutes if you’re on the computer for long hours. Get up, walk around, and look at objects far away to give your eyes a break.
  • Have a yearly eye exam. Since most people don’t have symptoms in the early stages of eye diseases, they often go undetected. However, an ophthalmologist or optometrist can find and treat problems before they become unmanageable. If you’re fifty or older, you should have a dilated eye exam annually, where your doctor can examine your eyes more closely.

Final Thoughts on Study Showing that Goji Berries Improve Vision

As you get older, you’re more vulnerable to health problems such as age-related vision loss. However, a new study by UC Davis found that goji berries could preserve eye health and protect against diseases like macular degeneration. After 90 days, participants had higher levels of the protective pigments lutein and zeaxanthin in their eyes.

Another study found that participants taking a goji berry supplement also had more macular pigment. However, in the first study, those who took a supplement showed no improvement. Therefore, it’s probably best to eat goji berries naturally before trying other options. Either way, the research proves the power of goji berries, and we can all benefit from their healing properties.

The 8 Different Types of Dementia According to Science

When people think of dementia, they often think about Alzheimer’s disease, but that is only one of eight types of dementia. It’s an umbrella term for memory, language, and thinking loss that interferes with someone’s daily life. However, dementia means the brain isn’t functioning well, including many types.

Experts say some types of dementia are treatable or reversible, but others are permanent. Learning about the different types can help you identify conditions in your or your loved ones early on. With early detection, there is a better chance of slowing the brain’s decline, and it offers more time for making healthcare decisions.

Dementia is likely to worsen over time, no matter which type. However, learning about the different types can help slow the progress as you’ll know how to ease the symptoms.

Scientists Explain the Eight Different Types of Dementia

Don’t lose hope if you or a loved one is diagnosed with one of these types of dementia. There are treatment options available, making early detection essential. The treatment will depend on the type of dementia, so pay attention to the differences to get started.

types of dementia

1. Lewy Body Dementia

Lewy body dementia is a common type of dementia, affecting nearly 1.4 million Americans. It’s more common in people older than 50, but getting it at a younger age isn’t unheard of. With Lewy body dementia, proteins form clumps around the nerve cells responsible for memory, motor control, and thinking.

Some days will be better than others, and it might even seem like the person is back to normal. Then, there will be days when they are out of it, and it’s hard to see who they are.

Symptoms of Lewy Body Dementia

The symptoms of Lewy body dementia depend on where the clumps form first. The symptoms include:

  • Visual hallucinations
  • Delusions
  • Acting out their dreams
  • Impaired memory
  • Inability to plan activities
  • Difficulty making decisions
  • Blanking out
  • Unusual and unexplained sleepiness
  • Unable to process information
  • Inability to pay attention
  • Lack of alertness

As the condition worsens, the patient might also suffer from the symptoms of Parkinson’s. These symptoms include the following indicators:

  • Rigid muscles
  • Tremors
  • Difficulty walking
  • Fluctuating moods and awareness

2. Creutzfeldt-Jakob Disease

This disease is rare, affecting around 350 Americans each year. While it doesn’t occur often, it is fast-moving and fatal. An infectious protein causes Creutzfeldt-Jakob disease in the brain, causing normal proteins to misfold into abnormal shapes.

The infectious protein can be inherited, but it can also come from eating the meat of an infected animal. Additionally, it can come from a medical procedure when an infected tissue gets implanted in the body.

Symptoms of Creutzfeldt-Jakob Disease

The symptoms of Creutzfeldt-Jakob Disease progress quickly, resulting in a rapid decline in the patient’s health. Watch for the following signs early on:

  • Depression
  • Mood swings
  • Confusion
  • Agitation
  • Difficulties with memory
  • Poor judgment
  • Trouble walking
  • Muscle twitches
  • Involuntary movements
  • Hallucinations
  • Blindness

3. Alzheimer’s Disease (probably the best-known type of dementia)

This disease is the most common type of dementia, making up 60-80% of the cases. It occurs when plaques in the brain destroy brain cells and their connections.

The plaques can start developing many years before you experience any symptoms. Alzheimer’s symptoms typically begin when someone is in their 60s or 70s, but, in rare cases, it can happen sooner.

Symptoms of Alzheimer’s Disease

The symptoms typically progress steadily over several years. At first, it might seem like typical instances of a terrible memory, but you’ll notice a decline over time. The symptoms include:

  • Forgetfulness
  • Repeating things many times, sometimes in the same conversation
  • Being unable to retain new information
  • Confusion performing simple tasks
  • Getting lost
  • Memory loss
  • Difficulty making plans
  • Frequently losing things
  • Mood swings and personality changes

As the disease progresses, the symptoms worsen. Then, you’ll want to watch for:

  • Confusion about the time of day
  • Difficulty following a conversation
  • Forgetting the names of loved ones
  • A decline in the ability to speak
  • Issues with walking
  • A struggle with eating without assistance

4. Huntington’s Disease

Huntington’s disease is an inherited brain disorder passed down through the Huntington gene. It is progressive and affects the part of the brain that affects movement, behavior, and mood. This disease affects nearly 40,000 Americans, and there is a 50-50 chance of passing it to the patient’s child.

Symptoms of Huntington’s Disease

The symptoms typically begin between thirty and fifty years old, but you might recognize them earlier or later. Symptoms vary based on the severity of the disease, but patients will likely experience them all at some point. The symptoms include:

  • Difficulties planning and organizing
  • Having a hard time remembering things
  • Struggling to stay on task
  • Being unable to hold a cup steady
  • Involuntary movements
  • Slurred speech
  • Abnormal twisting of body parts, including the arm, knee, or foot
  • Memory loss
  • Lack of judgment

types of dementia

5. Wernicke-Korsakoff Syndrome

A thiamine deficiency causes this degenerative brain disease. Thiamine, also known as vitamin B1, can be lost due to long-term alcoholism. Severe weight loss or anorexia can also cause low levels of thiamine.

Symptoms of Wernicke-Korsakoff Syndrome

People with Wernicke-Korsakoff syndrome can do a good job holding a social conversation. Many people won’t even recognize that anything is wrong at first. However, when symptoms appear, they include:

  • Memory loss
  • Vision problems
  • Lack of concentration
  • Disorientation
  • Ataxia
  • The inability to coordinate voluntary movement
  • Inability to retain information
  • Making up portions of their memories that they can’t recall

6. Vascular Dementia

This type of dementia is the second most common type, accounting for about 15-20% of cases. It occurs when blood flow is blocked from part of the brain. The blockage deprives the neurons of oxygen and damages or kills the cells.

Vascular dementia often occurs after a significant stroke but can also happen after a series of small strokes or transient ischemic attacks. It can also come from a brain hemorrhage or narrowing blood vessels. People over 65 are most commonly affected by vascular dementia, and the risk increases with age.

Symptoms of Vascular Dementia

The symptoms vary depending on the severity of the situation. When a stroke has taken place, it depends on which part of the brain was affected. Additionally, when one symptom sets in, it’ll likely stabilize for a bit before worsening.

The symptoms include:

  • Difficulties with language
  • Inability to pay attention
  • Inappropriate emotional outbursts
  • Poor planning
  • Judgment
  • Memory loss
  • Confusion or agitation
  • Impaired motor skills
  • Depression
  • Loss of bladder control
  • Hallucinations
  • Trouble speaking
  • Problems recognizing common sights and sounds
  • Personality shifts
  • Frequent falls

7. Frontotemporal Dementia

This type of dementia is less common as it affects only 60,000 Americans yearly. However, when people under 60 are diagnosed with dementia, frontotemporal dementia is the most common cause.

Frontotemporal dementia occurs when proteins attack the frontal and temporal lobes of the brain. These lobes are responsible for behavior, language, and motor function.

Symptoms of Frontotemporal Dementia

Frontotemporal Dementia starts in the frontal lobe, so it often affects mood and behavior first. Early on, it is often confused for a psychiatric disorder, but the symptoms escalate over time. Some of the symptoms include:

  • Aggression
  • Apathetic behavior
  • A lack of empathy
  • Unexplained personality and behavior changes
  • Inappropriate language
  • Acting out sexually
  • Unusual cravings and eating habits
  • Compulsions
  • Problems with speaking
  • Trouble writing
  • Decrease in comprehension skills
  • Muscle weakness and atrophy

8. Normal Pressure Hydrocephalus

Normal pressure hydrocephalus affects around 700,000 Americans, but only about twenty percent receive a correct diagnosis. It is a type of dementia that can be treated when caught early on, but it is often mistaken for other dementia types or normal aging.

Normal pressure hydrocephalus occurs when excess cerebrospinal fluid accumulates in the brain’s cavities. The fluid enlarges the cavities and interferes with brain tissue. It can happen when you hit your head on something or have some blood in your spinal fluid from infection or trauma.

These situations can prevent the area from draining well. In other instances, it might be that the patient is overproducing fluid but not draining it as quickly. This condition can be treated with a shunt, draining the fluid from your brain into the abdomen.

Symptoms of Normal Pressure Hydrocephalus

Normal Pressure Hydrocephalus is often diagnosed after a head injury, trauma, or infection. The cause is often unknown, but the symptoms tend to be the same despite what happened. The symptoms include:

  • Urinary incontinence
  • Difficulty with balance
  • Trouble walking
  • Cognitive problems
  • Short-term memory loss
  • Mood changes
  • Difficulty making decisions
  • Having a hard time performing tasks

Diagnosing The Different Types of Dementia

When a doctor diagnoses which type of dementia a patient has, they will collect information. The information will include the patient’s family health history, current symptoms, when the condition began, and the rate of progression.

Additionally, the patient might have blood tests, an MRI, a CT scan, or a spinal tap. Sometimes, the doctor will request a neuropsychological assessment assessing the patient’s ability to draw shapes and remember details. These tests will help narrow down which type of dementia a patient has.

Science Explains What Happens in the Brain During a Migraine

It’s estimated that around one billion people suffer from migraine headaches globally. This volume makes it the third most prevalent illness, behind tooth decay and tension-type headaches. A migraine headache is not your run-of-the-mill pain, however. Instead, it is a neurological (brain) disease that can have severe symptoms.

If you’ve ever had a migraine headache, you know how debilitating and painful they feel. They differ from everyday headaches that tend to pass quickly and easily. Migraines frequently occur due to complex neurological changes in some brain regions. The headaches can last from hours to days and may impact daily activities depending on severity.

Eight Common Symptoms of a Migraine Headache

While symptoms vary from person to person, these are general signs of a migraine:

  1. intense, pounding headache
  2. nausea
  3. vomiting
  4. trouble speaking
  5. light sensitivity
  6. fatigue
  7. sleep disruptions
  8. visual disturbances such as bright lines, flashing dots, or lights

Migraines can include any of these symptoms, though a throbbing, pulsing headache happens most frequently. However, migraine sufferers can experience many symptoms, and some may not have a headache. However, most people will notice strange sensations in the days leading up to a migraine.

migraine headache

Four Phases of a Migraine Headache

Changes in the brain can occur a few hours or even days before a migraine. Migraines tend to happen in four phases: prodrome (preheadache phase), aura, headache, and postdrome (migraine aftermath). Nearly 30% of people will experience symptoms before the migraine onset.

  1. This first phase can last a few hours or days. Not everyone will experience it because it may not occur each time. It’s also called the “preheadache” or “premonitory” phase. Common symptoms include difficulty concentrating, irritability, depression, trouble speaking, sleep disruptions, nausea, fatigue, light and sound sensitivity, food cravings, muscle stiffness, and increased urination.
  2. Aura: The aura phase may last between five minutes and an hour. Auras impact sensory, motor, and speech functions and are a warning sign of an impending migraine. They typically happen before a migraine but can also occur during or after. Only about 15-20% of people with migraines experience auras. Aura symptoms can include:
  • Blind spots in your vision
  • Seeing bright, flashing lines, dots, or lights
  • Numbness or tingling
  • Difficulty speaking or slurred speech
  • Ringing in your ears (tinnitus)
  • Temporary vision loss
  • Seeing zigzagging lines
  • Changes in smell or taste
  • A “funny” feeling
  1. Headache: A migraine headache can last anywhere from four to 72 hours. However, the term “headache” is a vast understatement because most people with migraines consider them debilitating. Some people experience it only on one side, but it can affect the head. Other symptoms during this stage include hypersensitivity, speech changes, loss of appetite, nausea, abdominal pain, fatigue, tender scalp, and pale skin. You may also experience dizziness, blurred vision, sweating, and chills.
  2. Postdrome: The postdrome stage may last for one or two days. It’s sometimes referred to as a migraine “hangover,” and about 80% of migraine sufferers experience it. Symptoms include the inability to concentrate, depression, fatigue, comprehension problems, and euphoria.

migraine headache

What Happens in the Brain During a Migraine Headache

During the prodrome phase, the warning signs of migraine occur due to changes in the hypothalamus. Typically, the hypothalamus keeps our hormones balanced, controls thirst signals, and maintains circadian rhythm. However, brain signals controlling these functions are disrupted because it’s more active during the days leading up to a migraine.

People experience transitory visual, speech, and motor disturbances in the aura phase. These sensations happen due to changes in electrical waves across cell membranes. It can spread quickly across the brain to the visual cortex, affecting blood flow and causing blind spots or other aura symptoms.

During the third or headache phase, changes in the trigeminal nerve occur. This nerve transmits sensory information like touch, temperature, and pain from your face to your brain. It also sends signals to the scalp and blood vessels near the cerebral cortex. When a migraine headache occurs, this nerve becomes overly active, which increases pain sensitivity. Even activities such as bending over or coughing, or sensations like light and sound, can seem excruciating.

What Causes a Migraine Headache?

Even though migraines are pretty standard, it’s still unknown precisely what causes them. Scientists only know that specific nerves in the blood vessels send pain signals to your brain. However, why the nerves respond that way is still a mystery. More research on the brain areas affected during migraines – the brainstem, cerebral hemispheres, and the nerves.

Certain factors such as genetics, gender, and stress can increase your likelihood of migraines. Around 80% of people with migraines have a family history of the disease. Also, women are three times as likely as men to have migraines. Women between 15 and 55 experience migraine headaches more often due to hormonal fluctuations. Finally, heightened emotional stress can trigger a migraine because of increased cortisol.

It’s also been observed that people with migraines tend to have comorbidities such as depression, panic disorder, strokes, and sleep disorders. It’s unclear whether migraines cause these illnesses or vice versa; however, scientists believe genetics plays a crucial role. Still, they haven’t been able to identify any gene in particular that causes migraines.

They know that specific genes control our sensitivity to environmental stimuli, which determines our pain response. Perhaps the neurons in the brains of migraine sufferers respond more strongly to environmental stimuli, leading to increased sensitivity.

These unanswered questions about migraine headache causes warrant more research in the future. However, people who suffer from migraines experience complex changes in their brains.

Final Thoughts on Brain Changes that Occur During a Migraine

Anyone who gets migraine headaches can attest to how unbearable they are. Despite being the third most common illness globally, it’s unclear what causes these painful headaches. Scientists know that changes in specific brain areas, such as the hypothalamus and cerebral hemispheres, can trigger them. However, they’re still unsure what causes the nerves to send pain signals to the brain.

Hopefully, we’ll have more answers on the mechanisms driving these headaches in the future. Knowing the cause would improve treatment plans and perhaps cure migraines altogether. Doctors prescribe pain medications for severe migraines or recommend over-the-counter pain relievers for mild symptoms.

Science Explains How a Healthy Immune System Works

A healthy immune system is a central part of survival and protection. It includes many organs throughout the body’s vast tissue and cell network. The function of the system is simple in concept but complex in detail. It must identify threats to the body, differentiate them from healthy objects, and eradicate unwanted intruders.

The overall function of the immune system can be tough to understand. It’s hard to comprehend the incredibly nuanced behaviors the system undergoes to protect you effectively. What’s the secret? What’s going on in your body?

Here’s how a healthy immune system works!

1.      White Blood Cells

White blood cells are crucial for the most significant roles in immune system responses. They can be found throughout the body, using lymphatic and blood vessels to travel around. A healthy immune system has plenty of white blood cells and can produce new ones.

Also known as leukocytes, white blood cells focus on seeking out pathogens and harmful microorganisms. When they detect these unwanted items, they multiply to meet these responses. They then send signals out to various other cells about the unwanted intruder.

healthy immune system

How Pathogens Impact  a Healthy Immune System

To destroy pathogens, white blood cells in a healthy immune system:

  • Are capable of recognizing pathogens quickly
  • Multiple and bind themselves to pathogens, thus completely engulfing them
  • Using various natural chemicals to destroy the pathogens

For the most part, white blood cells can quickly detect harmful germs. But some pathogens can be harder to see and can slip unnoticed, harming you and making you very ill.

How The Body Stores White Blood Cells

While white blood cells can travel throughout most of the body, they are stored in:

  • Bone marrow, that is, the fluid in the middle of bones
  • The thymus, which is a gland beneath the neck nestled between the lungs
  • Lymph nodes are small glands connected by lymphatic vessels throughout the body
  • The spleen is a blood-filtering organ just above the abdomen and to the left

There are two primary white blood cells in a healthy immune system. The first is called a phagocyte. These cells are responsible for surrounding, engulfing, and breaking down pathogens. To a degree, they “eat” the germs they’re trying to eliminate. Types of phagocytes include:

  • Macrophages, which remove dying and dead cells and seek out pathogens
  • Mas cells, have numerous different jobs that include anti-pathogen defense and wound healing
  • Monocytes, which are very large phagocytes with multiple jobs
  • Neutrophils, which are the most common phagocyte type and typically attack bacteria

But what, then, about the second type?

2.      The Role Of Lymphocytes

The second type of white blood cell is lymphocytes. These have a particular purpose in recognizing previous pathogens and attacking them should they appear again. This allows the body to “remember” the best way to tackle various microorganisms practically, and safely.

There are two different kinds of lymphocytes. The first type is called a B lymphocyte. This type of lymphocyte, also called a B-cell, remains in the bone marrow where it is created. They’re responsible for antibody production and carry alerts to other lymphocytes.

Antibodies are a kind of protein that binds antigens. Antigens are any pathogen that triggers an antibody response. When B-cells realize an invading antigen, antibodies mark that invader for the rest of the immune system to find and destroy it.

Common Antibodies Include The Following:

  • IgA, protects orifices in the body by existing in fluids like saliva and tears
  • IgD, which remains with B-cells to help kick-start immune responses
  • IgE, which protects you from parasites but also triggers allergies and allergic reactions
  • IgG, or immunoglobulin, marks various microorganisms for other cells to handle
  • IgM, which kills bacteria

The second type of lymphocyte is T-lymphocytes or T-cells. After creation, these cells travel to the thymus and focus on altering leukocytes and destroying intruder cells. Helper T-cells do the former role, while killer T-cells perform the latter.

Lymphocytes of all kinds also release chemicals known as cytokines. These molecules are designed to signal various body parts and are involved in immune responses differently. A healthy immune system’s cytokines include chemokines, interferons, interleukins, and lymphokines. These cytokines affect lymphocytes and other cells by stimulating inflammatory responses.

Inflammation at this controlled level is crucial for repairing tissue, fighting antigens, and dealing with infections. This is why, for example, fevers are a typical response to the presence of an unwanted virus. Inflammation helps to strengthen the immune system when it needs that extra kick.

It is worth noting, of course, that chronic inflammation is unhealthy and can cause numerous different issues in the body. As with all things, an excess of this response will harm you more than help you.

3.      The Types of Immunity

Each person has a different immune system, but for the most part, a healthy immune system will become stronger over time. This is why children are more prone to illness than adults. This is because the immune system is good at handling antigens it has already encountered.

Kids who get sick are exposed to many different pathogens that their body has to learn to fight. These germs and microorganisms are remembered by the body, allowing a better, more robust response in the future.

Eventually, repeated exposure to an antigen can cause the body to develop immunity to that particular intruder. Essentially, your white blood cells will be able to destroy the antigen the second it sees it. This is most obvious in cases like chickenpox, where if you get the disease once, your body doesn’t get it again.

This impressive defense is known as immunity. There are three kinds:

·         Innate Immunity

Human beings are naturally born with some level of immunity. This allows them to fight primary germs and pathogens that may harm other animals or living creatures. The human body cannot get certain diseases, even with direct exposure, except in sporadic cases. Studies show that this is due to unique pattern recognition receptors as immune sensing.

·         Adaptive Immunity

Also known as acquired immunity, this refers to immunity learned through exposure over time. It may come from sickness or vaccinations. Some people call this immunological memory, as it’s an example of a healthy immune system capable of remembering past intruders’ faces. Studies show that this involves the identification of “signature” features of various antigens.

·         Passive Immunity

This type of immunity is temporary and comes from quick sources. The most obvious example of this is in babies. Babies can receive immunity from specific antigens by consuming antibodies through breast milk. They lose that immunity when they are weaned off the milk or don’t consume it for a while.

4.      Disorders That Affect The Immune System

Not everyone has a healthy immune system; several conditions can affect the body’s natural defenses. These include the following conditions:

·         Allergies

A healthy immune system responds to allergens by expelling them and quickly removing them. Allergy diseases, however, because that response can dial up to 11. The severity of such allergies can even become life-threatening in some cases.

·         Autoimmune Disorders

Autoimmune disorders occur when B-cells misidentify threats, producing autoantibodies. Autoantibodies attack the body instead of invader cells, thus making you fight your body by considering things like organs, cells, and tissues unfamiliar invaders. On the other hand, a healthy immune system can fight off this attack.

·         Immunodeficiency

Immunodeficiency refers to an under-activity of the immune system. This can cause a genetically inherited disease, such as SCID, or occur due to diseases like cancer or HIV. It can also come from specific medical treatments and medications, like chemotherapy.

Individuals with these disorders will need special treatment and unique considerations to keep themselves safe and healthy.

Final Thoughts On How A Healthy Immune System Works

The human immune system is an essential part of the survival of our species. Without it, we would be highly vulnerable to various diseases and illnesses. Therefore, we would have likely gone extinct a long time ago!

Psychology Explains Why Bullies Control Conversations In A Relationship

Do you know a bully who uses manipulation to control conversations and silence others? Is your partner one of these toxic people?

Our understanding of abuse and abusers goes further and further every day. As times change, we’ve learned about toxic relationships and how abusers control conversations, prey on their victims, and enact their will on others. Gone are the days when we assume that only physical abuse counts as a severe problem. We have a greater understanding of the subtleties of abuse and control.

Studies show that control is a critical factor in abusive relationships and situations. Toxic people feel the need to control, successfully manipulate, blackmail, and abuse those around them. Think about it: if you’re not under someone’s control, their power over you significantly diminishes.

But control is a complex thing. In fact, it’s not always apparent that someone’s trying to exercise control over another. In close relationships, especially romantic partnerships, the line between guidance, communication, and control can blur when an abusive person learns to be subtle. They know small ways to steer their partner in a harmless way but is causing a significantly toxic dynamic and harming that partner.

So, how can someone accurately detect when someone exerts this control over others? The first step is noticing how a partner controls the narrative, thus revealing a toxic nature. When you see through a bullying partner’s lies, facades, and sneaky methods, everything else becomes much more apparent. Here’s how people control conversations to bully their partners into compliance.

1.      They Control Conversations By Shifting Blame

A healthy relationship involves people willing to admit their mistakes and take accountability for them. There are no situations where a balanced relationship will have only one person always “in the wrong.” The truth is that there are always ways both parties can work together to improve and further their relationship.

But abusers never want to admit their faults. They want to shift that onto everyone else to avoid blame. In a relationship, they’ll push responsibility to bully their partners out of asking for their accountability. They’ll make their partner believe they’re innocent of controlling conversations and deflecting blame to escape likely consequences. This happens in the following ways:

conversations

·         They Make It Their Partner’s Fault

This is the most common way an abuser will try to control a conversation. When conflict arises, they’ll reframe scenarios to blame their partner. Sure, they were responsible for doing the laundry, but have you considered that they’ve had a terrible week? How could you dare to expect them to perform that responsibility? And sure, you said you felt uncomfortable with how they were constantly ogling their ex but isn’t that your fault for being so insecure? And yeah, they were mean to your best friend, but you should know they don’t like social situations, so it’s your fault for expecting otherwise! This is how abusers twist problems to blame their partners, even in ridiculous ways.

·         They Blame Other People

Abusers always act as if they’re powerless. Ironically, this is the behavior that often gives them the most power. They’ll work like the world is against them. They will say that their actions and behavior result from external factors, saying that once those factors are gone, they’ll behave much differently. They’ll point fingers at everyone and everything, pretending they have no role in these circumstances. They control conversations so their partner unites against an imagined enemy.

·         They Appeal To Your Emotions To Control Conversations

Even when something is an abuser’s fault, they’ll find a way to appeal to your emotions, so you let things lie. They’ll cry about how hard their week has been, mention their mental health struggles, or talk about wanting to harm themselves. Besides that, they will sob about how they’ll never be worthy of their partner or how nothing they do will ever be enough for the relationship. They’ll say outlandish, extreme things so that their partner’s instinct is to comfort them. Even though they’ve technically admitted fault here, they’ve made it so that this fault seems excusable. Their partner might even feel guilty for making them have this ultimately fake emotional reaction. At its core, this is just another way of playing the victim.

Some abusers go above simply deflecting blame. They also gaslight partners by entirely and utterly reframing different scenarios. The goal is to make their partner question their perception of reality. They may treat their partner like crazy, be overly sensitive, or misremember details.

2.      To Control Conversations, They Flood Partners With Negativity

Constructive criticism has a place in a relationship when delivered respectfully and positively. But abusers aren’t looking to be respectful. They want to control conversations, which they can achieve via verbal abuse and bullying. They’ll flood their partner with negativity, leaving them vulnerable and hurt to maintain power.

Research shows that verbal abuse can have a vast negative effect on self-esteem and mental well-being. Abusers are very good at starting their verbal abuse in small ways that only slightly unravel their partners’ confidence. Over time, their words escalate in severity and negativity, and due to the unraveling mentioned above, their partners feel like they deserve that negativity. An abuser may control conversations through negativity in the following ways:

·         They’re Never Satisfied

An abuser’s partner will often try their best to earn the validation and approval of the abuser, finally picking apart their self-esteem. Abusers cement their bullying by intentionally refusing to be satisfied. No matter what their partner talks about, they control conversations, pointing out something wrong in everything their partner says. Their partner, in turn, shrinks more and more.

conversations

·         They Frame Cruelty As Honesty

Honesty can be painful, and sometimes, we must speak brutal truths. But abusers don’t do this in any constructive way. They intentionally speak as cruelly and harshly as possible to cut to their partner’s core. They control conversations with this unnecessary cruelty. They say they’re only being honest when called out on this bullying behavior. They insist that it’s for their partner’s good and that they only say what they must. Partners under their control will believe them.

·         They Insult Their Partners To Control Conversations

There’s a difference between consensually “insulting” banter and insults that leave their partners feeling small. An abuser can control a conversation by dolling out a well-timed insult that cuts to their partner’s core. They often do this, mentioning these criticisms so often that it becomes a regular part of a conversation with them. Over time, their partner gets used to this and accepts it, not realizing that each insult damages them deeply.

3.      They Refuse To Engage to Control Conversations

When an abuser finds themself in interactions with their partner that they don’t want to be a part of, they control conversations by simply not engaging. According to research, this is a stonewalling tactic–a common predictor of the end of a relationship.

Stonewalling can take many different forms, and it can happen accidentally. But abusers use this mechanism to escape a conversation they don’t want. This is because they want to discuss this on their terms or want the subject to be dropped. They may do this in the following ways:

·         Silent Treatment

An abuser may completely ignore their partner to control conversations. By giving them the cold shoulder, an abuser can force their partner into a hopeless situation. Since they’re not going to engage until the topic plays out or their partner apologizes, the abuser manages to “win” on their terms.

·         They Control Conversations By Shutting Down Communication

In the middle of an argument, an abuser may stop responding and walk away for no discernable reason. They’ll offer no communication about what they’re doing or why. It’s like being ghosted but face-to-face. It’s worth noting that there’s nothing wrong with taking a break during a heated conflict to recollect your thoughts. But that’s not what an abuser in this scenario is doing. They’re intentionally derailing to get their way and control conversations, not taking a breather. They demand only to discuss things on their terms.

·         Treating A Partner “Oddly”

An abuser might get their message across to their partner by treating them “oddly” whenever a particular topic arises. They’ll suddenly act strange or antagonistic while insisting nothing’s wrong. This conditions their partner to try and avoid that subject to avoid the sudden “weird” treatment. This treatment can include not making eye contact, withholding affection, or physically distancing themselves.

·         Acting Like Their Partner Needs To Be Disengaged From

When an abuser feels that their partner is finally building the courage to call them out properly, they’ll quickly get their gaslighting going. They’ll act as if their partner behaves erratically or in a “crazy” or sensitive way. They’ll disengage while performing like the rational, level-headed person, saying they’re going to let their partner.

Final Thoughts On How Toxic People Control Conversations To Bully Their Partners

Abusers find different ways to control conversations to bully their partners. They’ll change narratives so they must never accept the fault for any situation. Moreover, they will flood their partners with negativity and verbal abuse to erode their self-esteem and claim higher ground. They’ll refuse to engage until conversations are on their terms.

These aren’t the only ways that abusers may control conversations. There are many methods by which this kind of bullying can be done. An abuser’s goal is to control, and they’ll develop all sorts of behaviors to get their desired outcome. You must be alert to these mechanisms to avoid falling under their spell.

If you feel your partner is harming you this way, don’t hesitate to seek help. Talk to someone in your social circle or reach out to a professional. Throughout this process, keep yourself aware of your self-worth and the various control methods your partner may be using. And, above all else, stay safe!

Owls Inspire Engineers to Make Quiet Wind Power Turbines

A study by researchers from Xi’an Jiaotong University discovered how to reduce noise from wind turbine blades. The technology would also apply to aircraft and other machines with airfoils. The inspiration for the new design? Owl wings.

The prevalent sound from aeronautical and turbine engines such as drones, wind turbines, and airplanes comes from trailing-edge noise. Many urban areas consider it a priority to reduce this type of noise pollution when possible.

So, to help with that goal, the research team analyzed the characteristics of owl wings to improve airfoil designs. Using this technology to create wind turbine blades and other airfoils could dramatically lower trailing-edge noise. The research has been published in Physics of Fluids by AIP Publishing.

Owls Inspire Noise-Reduction Technology Wind Turbine Blades

Owls inspired their invention due to their serrated wings, which break up airflow and absorb sound. They also have a flexible fringe toward their wing’s trailing edge or back part. This breaks up the air even more, considerably reducing aerodynamic noise.

“Nocturnal owls produce about 18 decibels less noise than other birds at similar flight speeds due to their unique wing configuration,” said author Xiaomin Liu. “Moreover, when the owl catches prey, the shape of the wings is also constantly changing, so the study of the wing edge configuration during owl flight is of great significance.”

When air passes along the back of an airfoil or wing, it produces trailing-edge noise. This airflow creates turbulence along the top and bottom surfaces of the airfoil. When these two airflows meet along the trailing edge, they scatter and make noise.

Prior studies investigated serrated trailing edges, discovering that these serrations helped suppress the noise of rotating machines. Unfortunately, the noise reduction of the wind turbine blades mainly depended on the final application and wasn’t guaranteed in all cases.

“At present, the blade design of rotating turbomachinery has gradually matured, but the noise reduction technology is still at a bottleneck,” said Liu. “The noise reduction capabilities of conventional sawtooth structures are limited, and some new nonsmooth trailing-edge structures need to be proposed and developed to tap the potential of bionic noise reduction further.”

wind turbine blades

Study on How Serrated Airfoils Reduce Noise

The researchers utilized noise calculation and analysis software to perform several studies for this study. These involved detailed measurements of simplified airfoils that resembled owl wings. They applied these results to reduce the noise of rotating machinery.

The noise decreased when they improved airflow near the trailing edge and optimized the airfoil’s shape. One peculiar finding from the study was that asymmetric serrations resulted in more significant noise reduction than symmetric designs.

They also noted that noise reduction depended heavily on operating conditions. So, the team said that the airfoil designs would require customizations based on the specific application.

For instance, wind turbine blades have complicated incoming flow conditions requiring a more generalized noise reduction approach. Therefore, scientists must investigate how noise reduction technologies perform with various incoming flows.

Either way, the team believes their work will help inform airfoil design in the future.

Other Studies on the Impact of Wind Turbine Noise Pollution

As the demand for wind energy keeps increasing, scientists have been scrambling to tackle noise pollution. Wind turbine blades disturb residents living near wind farms to such a degree that experts created the Wind Farm Noise Study. Researchers from Flinders University used machine learning and other signal processing techniques to determine how wind turbines impact humans.

They found that wind turbine blades’ nighttime ‘swoosh’ noise disrupts communities the most. Scientists estimate that nearby residents hear this sound, technically called ‘amplitude modulation’ (AM), five times more often at night than during daytime hours. Of course, wind direction, wind farm distance, and season also factor into these results.

“The noise seems to worsen after sunset when amplitude modulation can be detected for up to 60% of the nighttime at distances around 1 km from a wind farm. At greater than 3 km, amplitude modulation also occurs for up to 30% of the nighttime,” said Flinders University Ph.D. candidate Duc Phuc (‘Phuc’) Nguyen, who led the study.

Researchers created the Wind Farm Noise Study to investigate how noise from wind turbine blades impacted sleep for residences near wind farms. Scientists continue researching the potential adverse effects wind turbine noise can have on humans.

Dr. Kristy Hansen, an acoustic expert who also participated in the study, said wind turbine noise largely depends on wind direction. Those living in downwind and crosswind conditions will likely hear wind turbine blades more often.

“We found that AM occurs most often during these wind directions,” she says. “Using these recent advances in machine learning, we have been able to develop an AM detection method that has a predictive power close to the practical limit set by a human listener.”

How to Reduce Exposure to Noise Pollution

Of course, noise pollution doesn’t just come from wind turbine blades. For example, if you live in a big city, you probably encounter your fair share of noise. You can still protect yourself from excess noise with these tips:

  • Wear noise-canceling earplugs or earphones. These can help reduce your noise exposure, especially during evening hours when you’re trying to sleep.
  • Soundproof your home. Install double-paned windows to block the maximum amount of sound if you have the means. Ensure the weather stripping around doors and windows seals tight as well.
  • Opt for carpet instead of wood or tile floors. The rug will absorb sound much better and keep your feet warm in the winter!

Final Thoughts on Making Wind Turbine Blades Less Noisy

We’re getting closer to transitioning from fossil fuels to clean energy sources each day. Wind turbines will have a massive role in this new era of energy generation. However, it’s becoming clear that wind turbines also have a few downsides, such as creating noise pollution for nearby residents.

Xi’an Jiaotong University’s scientists have studied owl wings’ characteristics to help improve airfoil designs. They found that building airfoils with serrated edges significantly reduced noise like those on owl wings. More research is needed, but wind turbine blades and other rotating machinery will hopefully operate more quietly in the future.

Science Explains How A Sleep Deficiency Changes Your Food Cravings

Food is something that most people have a love-hate relationship with. It can bring people together, an integral part of many cultures. But it can also be someone’s worst enemy, such as sleep loss. Unfortunately, nutritional education is not the main focus of society at all.

And socioeconomic factors affect people’s diets. If you are from a low-income household, you don’t have the luxury to buy organic produce, so you settle for much cheaper fast food. Coupled with how society looks down on everyone with a little bit of fat on their bodies. This societal perception pushes many people into having an unhealthy relationship with food.

But these are not the only factors that can influence what you eat or how much you eat. Neuroscientists have found a correlation between sleep deficiency and food cravings. And it might indicate why making sure you have a clear sleep schedule is more important than it seems. Insomnia and lack of sleep are issues that affect all aspects of your life, and your nutrition is one of them. Read on to understand the correlation between sleep deprivation and food.

What Causes Insomnia And Other Sleep Loss Issues?

Insomnia is a sleep disorder that makes it hard for people to fall or stay asleep and even causes them to wake up too early. Even if you feel tired, you are unable to fall asleep. Instead, you end up staring at your ceiling, wishing you could fall asleep. It’s a more common disorder than most people might think. This disorder is the leading sleep issue, but you could also suffer from sleep apnoea or narcolepsy.

Sleep apnoea happens when your breathing starts and repeatedly stops, leading to a lack of energy. And narcolepsy makes people experience sudden periods of sleepiness during the day. Still, the main reason people lose sleep is that they suffer from various insomnia degrees. Most adults experience short-term (acute) insomnia at some point. This lasts for a few days, at most a few weeks.

sleep deficiency

Usually, acute insomnia results from stress, anxiety, or a traumatic event. But some people struggle with long-term (chronic) insomnia, which lasts for months or even longer. Insomnia can be a problem by itself or can be associated with other conditions. Stress is a prevalent factor that causes sleeplessness. But traveling, a busy work schedule or generally poor sleeping habits can factor in. In the case of chronic insomnia, more severe conditions can be involved.

The Connection Between Mental Illness and Sleep Loss

Mental health issues like depression, anxiety, or PTSD can disrupt sleep patterns. Side effects of certain medications can also cause insomnia. Medical conditions like cancer, diabetes, asthma, and more also lead to sleeplessness. Because of how many issues can lead to insomnia, this disorder is something that you’ll almost certainly struggle with. But even if you don’t have insomnia, the mere business of life can make you lose sleep.

A student might not be able to sleep for days during exam periods. An entry-level employee might have to work up to 12 hours a day. Even those disruptions in the sleeping pattern can lead to specific cravings.

How Sleep Loss Impacts Food Cravings

These are some reasons why insomnia can negatively impact unhealthy food cravings.

1.    Sleep Loss Often Stimulates Primal Brain Regions

Everyone knows from personal experience that sleep deprivation can make you less logical. But there is a neurological reason why that happens. Research from UC Berkley found that lack of sleep increases the activity of primal brain regions. Those are the regions that respond directly to rewards, like, for example, the taste of food.

The researchers used fMRI to scan the brains of almost two dozen young adults. They did two tests, one after a night of good sleep and one after a sleepless night. They measured the volunteers’ brain activity while showing them eighty images of foods. The foods ranged from healthy, low-calorie options to junk food.

And the results showed that sleep-deprived participants were likelier to choose junk foods as their favorite. Many past studies showed a correlation between insomnia and cravings for sweets and junk food. But this study was the first to show a clear cause for this. Sleep deprivation causes a decrease in the frontal lobe’s activity while increasing the activity of primal brain regions.

The regions responsible for complex decision-making were clouded by the lack of sleep. And, even if tired people knew they shouldn’t eat junk food, they still did it because the reward stimulated their brains. Fortunately, the same researchers suggested that fixing our sleep schedule will decrease these cravings. If you are struggling with overeating, check how much you sleep. If it’s less than seven hours a night, that might cause your weight gain.

2.    Tired People’s Brains Use More Energy

When you lose sleep, the brain becomes foggy and slow. Tasks that used to be simple and straightforward start to seem impossible. Even automatic responses start requiring actual effort. And the brain can’t do all these extra tasks alone. To function, it needs fuel and energy.

When you are sleep-deprived, you start experiencing changes in your neurotransmitters, such as dopamine. But most importantly, when the brain is tired, it promotes signals that increase your appetite. And Christian Benedict, a neuroscientist at Uppsala University, agrees with this idea. He says the brain cannot afford to waste energy controlling cravings and impulses. Instead, it encourages those signals to get the calories it needs to keep functioning.

Even though he warns about the impact of sleep on cravings, he also states that other aspects are just as important. Physical activity, accessibility to healthy food, and dietary restrictions are also essential. Even though sleep loss can make you want to eat sweets from time to time, it won’t cause a systematic issue.

sleep loss

3.    Lack Of Sleep Affects Your Senses

When you eat, your body has ways to signal that you are full. There are stretch receptors in your stomach that are activated when filled with water or food. These receptors signal the brain and create a feeling of discomfort if you overeat. Plus, other hormonal signals get released as nutrition enters the small intestine.

The smell is an essential sense that determines how hungry you get. If food doesn’t smell enticing, you might not even be interested in eating it. Research showed that the body parts responsible for the sense of smell don’t respond well when you are tired. The same goes for the components accountable for taste or food in the stomach. Because of this, tired people respond better to a more enticing smell.

And that craving is so powerful that you don’t stop considering how many calories food has. If you are struggling with insomnia, chances are you will be getting mixed feelings about how much food you need. Even if you are full, your brain might tell you you are still hungry.

Unfortunately, you will always crave unhealthy foods if you struggle with sleep loss. The best way to ensure you don’t cave in is to keep only healthy foods around you.

4.    Sleep Deprivation Leads To A Hormonal Imbalance

Lack of sleep is not something to be treated lightly. Statistics point out that people who sleep five hours or less per night are 50% more likely to be obese than people who sleep eight hours. This happens because sleep deprivation messes with your body’s hormonal balance.

Three powerful hormones are affected by lack of sleep. First, there is leptin, which is the hormone that regulates your appetite. This is the hormone that tells you it’s time to stop eating. But a lack of sleep dysregulates the levels of leptin in your body. This is because leptin peaks while you sleep, so a lack of sleep will affect how the hormone is released.

If not enough leptin is released, your brain will always feel that you are hungry. That’s why you will get more cravings when you are tired. Secondly, sleeplessness affects ghrelin, the hormone that tells your brain you are hungry. Your ghrelin levels can skyrocket even if you lose one night of sleep. You will feel like you are always hungry and can reach for snacks multiple times a day.

Lastly, insomnia affects the levels of insulin in your body. Insulin is a hormone responsible for fat storage, and responding to carbohydrate intake. If your insulin levels are too high, your body will store too much fat without a good reason. This fat can start accumulating around your organs, becoming dangerous for your health. And, when you don’t get enough sleep, your insulin levels rise, putting you at risk.

There is no way to control your hormones other than making sure you don’t do anything to imbalance them. And, naturally, that means getting the recommended amount of sleep.

food

Final Thoughts On How Sleep Loss Impacts Food Cravings

Sleep is an essential part of everyone’s life, and the quality of your sleep significantly impacts your health. It affects everything from energy levels to mood, appetite, and mental well-being. But the relationship between food and sleep is often overlooked. Losing some sleep may not seem like a big deal, but it can affect your cravings. People’s relationship with food is already complicated enough, so adding sleep disruption to the mic doesn’t help.

When you don’t get enough sleep, your brain starts signaling to the primal parts of your brain that something is wrong. Your brain responds to rewards more than normal, which triggers cravings. Because your brain needs more energy to function when it’s deprived of sleep, it needs more calories.

Plus, tiredness clouds your senses and makes specific receptors in your brain malfunction. Coupled with the fact that lack of sleep leads to a hormonal imbalance, your body will start receiving mixed signals regarding food. If you want to avoid craving sweet or junk food, ensure you get at least the recommended eight hours of sleep per night.

Marine Scientist Explains How Seagrass Fights Climate Change

According to marine scientist Carlos M. Duarte, the ocean harbors an unlikely ally in the fight against climate change: seagrass. Seagrasses evolved from terrestrial plants about 100 million years ago, which explains why marine meadows resemble grass on land.

While seagrasses account for only 0.1% of the seafloor, they remove about 33% of carbon in the seafloor each year. In total, seagrass meadows store over 10% of carbon in the oceans globally. Even more amazingly, they can absorb carbon up to 35x faster than Amazonian rainforests!

As climate change ramps up, this news couldn’t come at a more opportune time. While Duarte has studied seagrasses for nearly forty years, he only recently discovered their hidden power. Found in every continent except Antarctica, they’ve adapted over millions of years to colonize the ocean. About 50-60 different species of aquatic grasses exist worldwide, growing in shallow coastal waters where sunlight can easily penetrate.

As one of only 17 flowering plants to grow in marine environments, they’re a resilient, unique species indeed. Seagrasses populate by extending a rhizome – an underground stem that grows horizontally from 1cm to nearly five meters per year. Then, these networks of plant roots keep branching out along the seafloor to form large clones.

These clones can grow to massive sizes; Duarte discovered a clone in the Mediterranean that measured about 15 kilometers. This size equates to roughly the size of Manhattan! Even more remarkably, his team found that the clone originated from a seed that germinated 200,000 years ago.

Since it’s one of the oldest living organisms on the planet, UNESCO listed the seagrass meadow as a World Heritage Marine site. This fact means it’s protected from fishing or any other commercial activities. The mega clone meadow spans about 800 square kilometers and supports incredible biodiversity.

Marine Scientist Explains How Seagrass Can Help Fight Climate Change

climate change

Perhaps most importantly, Duarte’s team found that just one hectare of seagrass can sequester a massive amount of carbon. Shockingly, this relatively small area can store as much carbon as fifteen hectares of the Amazonian rainforest.

Of course, Duarte wanted to find out how the underwater plant could accomplish this monumental task. He discovered that since the plants have large canopies, they form an intricate web that filters out particles in the water. These particles settle in the seafloor and decompose slowly since seagrass soils don’t have oxygen. Carbon from decaying material then accumulates in the ground.

Also, seagrass meadows that grow in marine environments give them an advantage over forests. During forest fires, carbon in the soil returns to the atmosphere, contributing to a warming climate. However, since no fires occur underwater, the carbon in seagrass soils can remain safe for thousands of years.

When seagrasses grow, they raise the seafloor anywhere from 1 to 4mm per year. Over hundreds of years, they form reefs such as the extensive four-meter-tall meadow found in the Mediterranean. Duarte’s team even discovered a seagrass reef measuring 12 meters tall, which could hold an astonishing amount of carbon. Aside from sequestering carbon, seagrass offers another shield against climate change: protecting shorelines. Since climate change is already causing stronger hurricanes and rising sea levels, seagrass is crucial in defending infrastructure and property along the coast.

Finally, since seagrasses are flowering plants, they have seeds that humans can consume as marine rice. This crop doesn’t require arable land, water, fertilizers, herbicides, or pesticides, making it a sustainable food choice. Perhaps seagrass meadows could provide an answer to growing food insecurity around the globe shortly.

Seagrass Meadows Have Made a Comeback in the Last Century

Luckily, marine science and biology experts discovered the importance of seagrass just in time. As they learned about how it could fight climate change, they became aware of its vulnerability.

In the 1930s, a disease killed large areas of seagrass in the Atlantic. As it began to make a comeback, sewage and agricultural runoff wiped out these meadows worldwide. Anchors from large ships, trawling and dredging of the seafloor, and other mechanical operations threatened the aquatic grasses.

These factors compounded by the end of the 20th century, killing one-third of seagrasses worldwide. In the last few decades, scientists realized the urgency in protecting this fragile underwater plant. However, they’re still trying to map all the seagrasses worldwide.

Estimating the Impact

They estimate that seagrasses occupy between 150,000 to one million square kilometers of the ocean floor. Unfortunately, satellites can’t differentiate seagrass from other types of the seafloor, making it challenging to confirm its distribution.

Luckily, the scientists found a solution: tracking green sea turtles and tiger sharks that feed on or swim near seagrasses using satellite devices. They’ve uncovered new seagrass meadows in the Indian Ocean and the Red Sea by monitoring the marine animals. Through this method, they also discovered the largest seagrass meadow in the world off the coast of the Bahamas.

Now that they’ve begun mapping the seagrasses, they’ve also taken steps to protect them. Due to their efforts, seagrasses have started to recover in Europe, North America, China, Australia, and Japan.

They’ve also released millions of seeds to encourage new seagrass growth. In the early 2000s, Duarte’s colleagues released 7.5 million seeds in South Bay, along the coast of Virginia. Sixteen years later, the area measured 20 square kilometers; today, it’s grown to 36 square kilometers. This meadow sequestered so much carbon that Virginia passed a bill on seagrass restoration.

After researching seagrass’ impact on climate change and watching the meadows blossom back to life, Duarte feels confident we can restore our oceans. His team published a paper in the journal Nature last year that suggested it’s possible to “rebuild” ocean biodiversity by 2050. Ensuring the health of our oceans will bring us one step closer to stabilizing the climate.
