A Rare Genetic Mutation Gives Certain Individuals Resistance to Viral Infections

It started subtly, hidden within the immune systems of just a handful of people around the world. They weren’t heroes in capes, but they carried something remarkable—an unseen armor that blocked every virus nature sent their way. No flu, no measles, no chickenpox, not even a cold. Though they were vulnerable to some bacterial infections, […]

Scientists Discover a New Organ in the Throat

Anatomy, Biology / Jorge Paka

Scientists have identified a previously unknown organ: a pair of salivary glands located in the upper throat. This area of the nasopharynx, found behind the nose, was thought to contain only scattered microscopic salivary glands. However, the newly identified glands measure around 3.9 centimeters in length. Positioned above a cartilage structure called the torus tubarius,

World’s First ‘Behavior Transplant’ Between Species Achieved

Biology, Cell Biology / Samilton Santos

In a groundbreaking experiment, scientists have successfully transferred a courtship behavior from one species to another, causing the recipient to perform the foreign action as if it were innate. While cross-species gene transfers have previously influenced traits, this marks the first time an entirely new behavior has been genetically introduced into another animal. Rewiring the

France’s Largest Nuclear Plant Temporarily Shut Down by Jellyfish

Environmental Science, Evolution / Samilton Santos

A nuclear facility in northern France temporarily halted operations due to a jellyfish invasion but began resuming activity on Wednesday, according to operator EDF, with one of the four affected reactors now back in service. Europe’s Largest Nuclear Power Station Located near Dunkirk on the French coast, the Gravelines plant is the largest nuclear power

A Microbiologist Describes the Microbes Lurking Between Your Toes

Cell Biology, Healthcare / Ana Kiesse Zeleme

Your feet are thriving hubs for microbes. The spaces between your toes are loaded with sweat glands, and when enclosed in socks and shoes, they trap moisture in a warm, humid environment perfect for microbial growth. In fact, each foot can harbor a miniature rainforest of bacteria and fungi, with anywhere from 100 to 10

How 28.5 Million Shrimp Fuel One of Nature’s Most Drastic Fat Loss Transformations

Biology / Samilton Santos

Though humpback whales may appear serene and slow-moving, they undergo one of the most extreme weight-loss transformations in the animal kingdom—losing around 36% of their body weight in under two months. Remarkably, they manage this without the harmful tissue breakdown seen in other species during starvation. New research is now shedding light on the massive

Gut Cells Promote Self-Renewal By Signaling In Ways Similar To Brain Cells

Biology, Cell Biology / Ana Kiesse Zeleme

Gut support cells send precise messages—much like brain neurons—using fine extensions to guide the stem cells that maintain and repair the intestine. This finding could reshape how we understand tissue healing and gut disorders. The intestinal lining, known as the epithelium, undergoes constant renewal, replacing all its cells every four to five days. This process

AI-Enhanced Microscope Forecasts and Monitors Protein Clumping Tied to Brain Disorders

Biology, Cell Biology / Ana Manuel

The buildup of misfolded proteins in the brain plays a key role in diseases such as Huntington’s, Alzheimer’s, and Parkinson’s. However, these harmful proteins appear indistinguishable from normal ones to the human eye. The formation of protein aggregates typically occurs unpredictably and within minutes—making detection and analysis difficult. Yet, identifying and understanding these aggregates is

Spinal Implants Help Paralyzed Rats Walk Again

Biology, Evolution / Leandro Conceição

Scientists in New Zealand have developed a minimally invasive technique that successfully restored movement in paralyzed rats. This breakthrough brings us closer to treating incurable spinal cord injuries that cause lasting motor loss in humans and animals. Ultra-Thin Implant Delivers Targeted Spinal Cord Stimulation The University of Auckland team created an ultra-thin implant that delivers

No Biological Reason Dads can’t Wake up to a Baby’s Cries

Biology, Evolution, Uncategorized / Ana Manuel

A new study challenges the belief that women are biologically more responsive to a baby’s cries at night than men. The findings suggest that the gap in nighttime caregiving stems from social norms rather than biological differences. Often referred to as an “acoustic umbilical cord,” a baby’s cry forms a strong connection with their caregiver,
