Researchers taught young loggerhead turtles to associate certain magnetic fields with feeding, prompting a distinctive dance when they recognized the signal. After a magnetic pulse briefly disrupted their ability to feel magnetic forces, the turtles no longer performed the dance. This showed that hatchlings use a touch-based magnetic sense to determine their location. The discovery clarifies how these animals find their way across vast ocean routes. Read more ›

Scientists discovered that lowering a specific molecule helps microglia switch into a protective state that quiets brain inflammation in Alzheimer’s. A small group of these cells seems to have an outsized ability to keep the brain healthier. When a key signal is removed from them, Alzheimer’s symptoms worsen. This pathway may help explain why some people naturally have reduced Alzheimer’s risk. Read more ›

A new nasal-delivered nanotherapy shows promise against aggressive glioblastoma tumors. By activating the STING immune pathway using gold-core spherical nucleic acids, researchers were able to reach the brain without invasive surgery. When paired with drugs that boost T-cell activity, the treatment eliminated tumors in mice and built long-lasting immunity. The results suggest a powerful new direction for brain cancer immunotherapy. Read more ›

Worker bees stage coordinated revolts when viral infections weaken their queen and lower her pheromone output. This disruption drives many of the queen failures that beekeepers struggle with today. Field trials show that synthetic pheromone blends can prevent untimely supersedure, opening a path to more stable hive management. Read more ›

Scientists have uncovered a surprising second type of lion roar, using AI to decode vocal signatures with remarkable precision. This breakthrough sheds new light on how lions communicate and offers a powerful new tool for conservationists racing to protect shrinking populations. Read more ›

New measurements of radio galaxies reveal that the solar system is racing through the universe at over three times the speed predicted by standard cosmology. Using highly sensitive data from multiple radio telescope arrays, researchers uncovered a surprisingly strong dipole pattern—one that challenges longstanding assumptions about how matter is distributed across cosmic scales. The results echo similar anomalies seen in quasar studies, hinting that something fundamental about our universe’s structure... Read more ›

A first-of-its-kind trial is testing adult stem cell transplants for advanced dry macular degeneration. Early results show the treatment is safe and can significantly improve vision, even in severely affected patients. Participants gained measurable sight improvements in the treated eye. Researchers are now monitoring higher-dose groups as the therapy advances toward later trial phases. Read more ›

Migratory birds that fill North American forests with spring songs depend on Central America’s Five Great Forests far more than most people realize. New research shows these tropical strongholds shelter enormous shares of species like Wood Thrushes, Cerulean Warblers, and Golden-winged Warblers—many of which are rapidly declining. Yet these forests are disappearing at an alarming pace due to illegal cattle ranching, placing both birds and local communities at risk. Read more ›

Around 115 million years ago, northern Australia’s seas hosted a colossal shark that rewrites what we thought we knew about early ocean predators. New fossil discoveries show that modern-type sharks were experimenting with gigantic sizes far earlier than scientists believed, competing with the marine “monsters” of the dinosaur age. Read more ›

Water trapped inside tiny molecular cavities behaves in a surprisingly energetic way, pushing outward like people crammed in an elevator. When a new molecule enters these narrow spaces, the confined water forces its way out—boosting the strength of the molecular bond that forms in its place. Researchers from KIT and Constructor University have now proven this effect both experimentally and theoretically, showing that these "highly energetic" water molecules can dramatically...

Scientists discovered that deep earthquake faults can heal far faster than expected, sometimes within hours. Slow slip events in Cascadia reveal repeated fault movements that only make sense if the fault quickly regains strength. Lab experiments show that mineral grains can weld together under intense heat and pressure, acting like a natural glue. This rapid cohesion may be a missing factor in earthquake modeling. Read more ›

Scientists have uncovered a long-missing piece of the volcanic puzzle: rising magma doesn’t just form explosive gas bubbles when pressure drops—it can do so simply by being sheared and “kneaded” inside a volcano’s conduit. These shear forces can trigger early bubble growth, create escape channels for gas, and sometimes turn potentially catastrophic magmas into surprisingly gentle lava flows. Read more ›

People who smoke only a couple of cigarettes a day still face surprisingly high risks of heart problems and early death. A large review of long-term studies shows that even very light smokers can see their risk of heart failure climb sharply. While quitting leads to major health improvements, some risk remains for decades. The safest approach is quitting entirely, especially at younger ages. Read more ›

Researchers uncovered how estrogen subtly reshapes learning by strengthening dopamine reward signals in the brain. Rats learned faster when estrogen levels were high and struggled when the hormone’s activity was blocked. The findings help explain how hormonal cycles influence cognitive performance and psychiatric symptoms. This connection offers a new path for understanding brain disorders tied to dopamine.

A massive real-world study comparing tirzepatide and semaglutide reveals both drugs deliver strong, early cardiovascular protection—reducing heart attack, stroke, and death in adults with type 2 diabetes. While companies have claimed large differences favoring their own medications, researchers found only modest distinctions between the two blockbuster GLP-1 drugs. Read more ›

Researchers discovered that the common amino acid arginine can block harmful Aβ aggregation and reduce its toxic effects in Alzheimer’s disease models. In flies and mice, oral arginine lowered plaque levels, reduced inflammation, and improved behavior. Its strong safety record and low cost make it a promising repurposing candidate. The findings hint at a surprisingly simple path toward more accessible AD therapies. Read more ›

Researchers discovered that chemotherapy can accidentally trigger a stress alarm in immune cells, causing inflammation that damages nerves. Blocking this alarm protected mice from nerve pain and kept their nerves healthier. A drug already being tested for cancer may help do the same in people. Early blood tests suggest it may even be possible to predict who will develop these symptoms before they happen. Read more ›

A new airflow device from UBC Okanagan engineers traps exhaled aerosols almost immediately, sharply reducing pathogen exposure in indoor spaces. Early simulations suggest it could outperform existing ventilation systems by a wide margin. Read more ›

Scientists have traced kissing back to early primates, suggesting it began long before humans evolved. Their analysis points to great apes and even Neanderthals sharing forms of kissing millions of years ago. The behavior appears to have persisted through evolution as a social or bonding tool. Yet its patchy presence across human cultures hints at a mix of biology and cultural invention. Read more ›
