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

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,

Orcas Share Food with Humans as a Way to Build Familiarity

Biology / Jorge Paka

Researchers have observed an intriguing behavior in killer whales: they sometimes share their prey with humans. While we can’t ask the whales directly, scientists believe this may be an attempt to form connections with people. In 34 Cases Over Two Decades, Orcas Offered Food to Humans—Often Watching Closely for a Reaction A recent study analyzed

Ants Carry Spotted Lanternfly DNA in Honeydew, Helping Detect Infestations

Biology / Jorge Paka

Virginia might have a new partner in battling one of its most destructive insect pests. Researchers at Virginia Tech, led by Assistant Professor Scotty Yang from the Department of Entomology, have discovered a method to use ants to detect the presence of spotted lanternflies in new regions. Published in Pest Management Science and Neobiota, new

Scientists Discover Hidden Loading Dock Structure Within Human Cells

Biology / Jorge Paka

Researchers at the University of Virginia (UVA) have discovered a previously unknown organelle—an ultra-small, specialized structure inside human cells that plays a role in recycling cellular material. This breakthrough could pave the way for new treatments for a variety of diseases. Just like our bodies rely on organs to perform vital tasks, our cells contain

Wildlife Forensics Team Unveils Method to Spot Elephant Ivory Masquerading as Mammoth Ivory

Biology, Evolution / Jorge Paka

In an effort to protect elephants from extinction, the global community banned the trade of elephant ivory. However, mammoth ivory remains legal to sell, and the two types are hard to distinguish—particularly for those without expertise. This creates a potential loophole that illegal ivory traders can take advantage of. Stable isotope analysis may now offer

Scientists Develop Genetically Engineered Mosquito STD to Help Fight Malaria

Biology / Jorge Paka

Mosquitoes have been one of humanity’s deadliest foes for millennia, responsible for more deaths than any other animal. As mosquitoes grow increasingly resistant to conventional control strategies, scientists are turning to novel solutions to fight mosquito-borne illnesses. Genetically Modified Fungus Targets Malaria-Carrying Mosquitoes At the University of Maryland, entomologists have genetically modified a fungus to

Man Voluntarily Bitten by Snakes 200 Times Inspires New Hope for Antivenom Development

Biology / Jorge Paka

Feeling especially low the day after the September 11 attacks, Tim Friede went to his basement and allowed himself to be bitten by two of the world’s most venomous snakes. Four days later, Tim Friede awoke from a coma. “I know what it feels like to die from a snakebite,” he told AFP in a

Blood Clotting Discovery Heralds A “New Era In Vascular Biology”

Biology, Evolution / Ana Manuel

Scientists have uncovered a previously unrecognized biological process responsible for tissue and organ damage in low-oxygen conditions like heart attacks and strokes. The findings indicate that rupturing red blood cells, rather than blood clots, are to blame. The microvasculature—a network of tiny blood vessels—is essential for supplying oxygen and nutrients to body tissues. When these
