Scientists Use Engineered Stem Cells to Slow Aging in Monkeys, Study Reveals

Biology, Cell Biology /

BEIJING (WSYX) — Scientists have shown that genetically modified human stem cells can delay aging symptoms in monkeys, potentially paving the way for treatments aimed at age-related decline in humans. Stem Cell Therapy Cuts Aging Signs in Monkeys Without Side Effects Over a 44-week period, researchers treated cynomolgus monkeys with senescence-resistant mesenchymal progenitor cells (SRCs) […]

Lab-Made Artificial Life Can Grow and Divide Similarly to Natural Bacteria

Biology, Science /

Synthetic cells, created by merging elements of Mycoplasma bacteria with a chemically synthesized genome, can grow and divide into uniformly shaped and sized cells—much like natural bacteria. Craig Venter’s Team Creates Synthetic Minimal Cells with 473 Essential Genes In 2016, a team led by Craig Venter at the J. Craig Venter Institute in San Diego

Ancient Crocodile “Hypercarnivore” That Preyed on Dinosaurs

Biology, Science /

Scientists have uncovered an exceptionally well-preserved skeleton of a massive crocodile relative in South America, offering an unprecedented glimpse into its anatomy and behavior. Around 70 million years ago, this formidable predator prowled the land, hunting prey that included medium-sized dinosaurs. An international research team, led by Argentina’s Museo Argentino de Ciencias Naturales (MACN), has

A Rare Genetic Mutation Gives Certain Individuals Resistance to Viral Infections

Biology, Genetics /

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 /

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 /

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 /

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 /

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 /

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 /

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
