Part of your eye actually "breathes" oxygen from the air.

While most of the body relies on the bloodstream to deliver oxygen, the front surface of the human eye gets its oxygen directly from the air.

Specifically, the cornea, the eye’s transparent outer layer, is avascular — meaning it has no blood vessels.

This design preserves optical clarity so light can pass through unobstructed. But it also poses a unique challenge: how do these living corneal cells stay oxygenated? The answer is simple yet elegant—they absorb oxygen directly from the atmosphere.

To keep the eye healthy and functional without interfering with vision, the body uses two key strategies. First, oxygen diffuses straight from the air into the cornea’s surface.

Second, a clear fluid called the aqueous humor delivers additional oxygen to inner eye structures like the lens and the back of the cornea. Without red blood cells to carry oxygen, this fluid relies solely on diffusion, making direct contact with the air an essential part of keeping the cornea alive and transparent.

This new plastic dissolves in seawater – no microplastics, no trace.

The plastic, which was developed by scientists in Japan, could revolutionize the fight against ocean pollution.

Created by teams from the RIKEN Center for Emergent Matter Science and the University of Tokyo, this innovative material dissolves entirely in seawater within hours—leaving no microplastics, no toxic byproducts, and no environmental trace.

Unlike many so-called biodegradable plastics that still fragment into persistent pollutants, this plastic’s unique molecular structure allows salt ions to trigger complete disintegration into safe, bacteria-processable components.

Lab tests showed a 2-inch sample vanishing in just about an hour when agitated in saltwater. The material is non-toxic, non-flammable, and breaks down without releasing carbon dioxide, making it both environmentally and chemically safe.

Though still in development, its durability—especially when coated—makes it a strong contender for future packaging and marine applications. With global plastic pollution projected to triple by 2040, this breakthrough could represent a pivotal tool in safeguarding ocean health for generations to come.

BREAKTHROUGH: A new drug restores vision by regenerating retinal nerves

In a groundbreaking breakthrough, researchers at South Korea’s KAIST have developed a drug that regenerates retinal nerves and restores vision — something previously thought impossible in mammals.

By targeting the protein PROX1, which blocks retinal cell regeneration, the treatment reversed vision loss in disease-model mice and maintained the effect for over six months.

This marks the first time scientists have successfully achieved long-term nerve regeneration in the mammalian retina, potentially transforming treatment options for millions suffering from degenerative retinal diseases like retinitis pigmentosa.

The therapy uses an antibody to intercept and eliminate PROX1 before it inhibits Müller glia, the retinal support cells critical for neuron regeneration in fish but largely dormant in mammals.

Developed by biotech startup Celliaz Inc., the antibody effectively reactivates these cells' regenerative capabilities.

With plans for clinical trials by 2028, this discovery signals a hopeful future for those with currently untreatable vision loss and highlights the power of translating biological insights from nature into medical innovation.

We just found the brain region that controls numerical thinking and math.

A surprising discovery in epilepsy patients has revealed that numerical thinking activates the putamen — a brain region traditionally linked to movement, not math.

While studying brain activity during number-related tasks, researchers noticed significant involvement of this ancient structure, suggesting that our ability to understand numbers may be far more deeply rooted in the brain than previously thought.

This finding challenges long-held views that number processing is confined to areas like the parietal cortex and opens new doors to understanding the evolution of human cognition.

The implications go beyond theory. Recognizing the putamen’s role in numerical cognition can enhance precision in neurosurgery, helping surgeons avoid damaging vital areas during procedures such as epilepsy treatment or tumor removal. It also offers promising new directions for addressing math learning difficulties. By pinpointing how and where number processing occurs in the brain, educators and therapists may be able to design more effective strategies to support individuals struggling with math-related tasks.

This could bring an end to organ transplant lists.

For the first time ever, scientists genetically modified a pig organ and put it inside a human — and it worked.

In a groundbreaking medical achievement, surgeons in China have successfully transplanted a genetically modified pig liver into a brain-dead patient, with the organ functioning inside the human body for 10 days.

The experimental procedure took place at Xijing Hospital in Xi’an and is believed to be the first of its kind.

Scientists view the success as a hopeful step toward using pig livers as temporary, life-saving support for patients awaiting a transplant or recovering liver function.

The pig liver came from a Bama miniature pig engineered with six genetic modifications to reduce rejection risk and mimic human liver proteins. During the 10-day observation, the organ produced bile and albumin—key signs of function and compatibility. Although the patient had an intact liver and the pig organ was removed at the family’s request, experts believe this “bridging” method could revolutionize transplant care. The team’s innovative surgical technique may pave the way for safer, short-term xenotransplantation in critically ill patients.

Constantly worrying about events beyond your control significantly harms your physical health.

This persistent anxiety keeps the body's stress-response system activated, leading to chronic stress. Over time, such stress can weaken the immune system, making us more susceptible to infections and illnesses.

Additionally, chronic stress is linked to cardiovascular issues, including hypertension and an increased risk of heart disease.

The body's prolonged exposure to stress hormones like cortisol can also lead to digestive problems, muscle tension, and headaches.

Moreover, the mental strain from focusing on uncontrollable factors can lead to unhealthy coping mechanisms, such as overeating or substance abuse, further impacting physical well-being.

If you need help with this or related issues, it's out there. It gets better.
