In the tranquil curves of the Han River in central China, three ancient skulls remained hidden for nearly a million years. Over time, they were deformed by natural forces and buried in silence under layers of sediment. For years, scientists believed they belonged to a well-known part of our evolutionary story—Homo erectus, the upright human […]
Blood-producing stem cells, known as hematopoietic stem cells (HSCs), function best when they’re stable and well-rested—like managers keeping a factory running smoothly. But when the body faces stress, such as infection or injury, these cells quickly ramp up production of immune cells to defend against threats. Over time, repeated stress wears them down, causing them

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

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

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,

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 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

Scientists at the University of Bayreuth have successfully engineered the world’s first spider modified with CRISPR-Cas9 to produce red fluorescent silk. They achieved this using the common house spider species Parasteatoda tepidariorum. Spiders’ cannibalistic behavior and complex genomes make them hard to modify and breed in labs, limiting their use in research. To overcome this,

Even biologists only get a fleeting look at the lives of whales. Many species, especially deep-diving whales, remain largely unknown. Scientists are gaining a deeper understanding of the vital role whales play in marine ecosystems and the services they provide. Recent studies indicate that even whale urine is crucial for Earth. The Whale Pump: How

In many animals, skin color and patterns play crucial roles in camouflage, communication, and temperature regulation. Corn snakes, for example, exhibit various morphs with bright colors like red, yellow, or pink, and their dorsal spots may merge or form stripes. But what genetic and cellular processes drive these striking patterns? A team from the University
