Scientists discover a hidden “ID card” in cat urine

Cats rely heavily on scent to learn about one another, often gathering information from urine and other odor marks left behind in their surroundings. These chemical traces can continue communicating long after the animal that produced them has moved on. That creates a puzzle. Many odor molecules evaporate, break down,…

Scientists may have solved a 2,000-year-old Dead Sea Scrolls mystery

A longstanding mystery surrounding the Dead Sea Scrolls may have a new explanation. Researchers have debated for decades whether the Qumran sect actually followed its unusual 364-day calendar or whether the system existed mainly as a religious and theoretical ideal. A study from Tel Aviv University argues that both possibilities…

New nanoparticles make hidden chemical differences light up

Engineers at the University of Toronto have developed a new type of dye-sensitized nanoparticle that can detect chemicals at extremely low concentrations while also telling apart molecules that are nearly identical in shape. The tiny particles produce a light signal after attaching to the chemical they are designed to detect.…

A 66-million-year-old tooth reveals T. rex was nearly as warm as a human

For more than a century, scientists have tried to reconstruct the biology of Tyrannosaurus rex from bones, teeth, footprints, and other traces left behind more than 60 million years ago. Fossils discovered as far north as Alaska have suggested that T. rex could tolerate cold conditions, adding to evidence that…

Einstein’s “spooky action” just survived one of physics’ most extreme tests

Physicists at the University of Oxford have helped demonstrate that one of quantum physics’ strangest phenomena, quantum entanglement, can persist even among some of the heaviest and shortest-lived particles ever produced. The finding, made with CERN’s powerful Large Hadron Collider, has been published in Physical Review Letters. Quantum entanglement occurs…

Hurricane Hunters reveal 4 warning signs that a storm is about to strengthen

Tropical cyclones generally need to become vertically organized before they can grow much stronger. That means the storm’s rotating centers at different levels of the atmosphere must line up rather than remain tilted away from one another. Using nearly three decades of observations from NOAA Hurricane Hunter aircraft, researchers have…

Hidden gut defect that may explain why IBD keeps coming back

Researchers have identified early molecular warning signs of inflammatory bowel disease that may appear before symptoms and remain active even when patients seem to be doing well. The study, led by WEHI in partnership with the Royal Melbourne Hospital, uncovered a hidden defect in intestinal cells that can make them…

A deadly ebola relative is surging after years in the shadows

A growing outbreak of the rare Bundibugyo virus in the Democratic Republic of Congo is drawing attention to a broader problem in global health: how to prepare for dangerous diseases that appear only rarely but can still cause deadly outbreaks. In a review article published in the New England Journal…

New chemical wipes out 95% of termites without harming humans

Drywood termites are remarkably good at disappearing into the very material they destroy. Instead of building obvious nests, they can spend nearly their entire lives hidden inside beams, framing, furniture, and other dry wood, slowly carving out galleries as a colony grows. That hidden existence makes them difficult to find…

A giant crater may reveal the origin of Mars’ doomed moon

Mars’ innermost moon, Phobos, has puzzled planetary scientists for decades. One of the biggest unanswered questions is where it came from. Some researchers think Phobos is an asteroid that was captured by Mars, while others argue that it formed from debris thrown into orbit after a massive object slammed into…

This deep-sea enzyme survives heat that destroys most proteins

Microorganisms are capable of some extraordinary chemistry. One example is nitrogen fixation, a process that converts nitrogen gas (N2) into a form living organisms can actually use. Nitrogen makes up about 78 percent of Earth’s atmosphere, but plants and animals cannot use it directly because the two nitrogen atoms in…

This tiny organism can shrink to one quarter its size in milliseconds

A tiny aquatic organism made of just one cell can compress its body to one quarter of its original length in under five milliseconds, hundreds of times faster than a person can blink. Scientists have now identified the unusual mechanism behind this remarkable movement. The organism, Spirostomum ambiguum, relies on…

Scientists find that “perfect” systems may be surprisingly fragile

Perfection may not always be the best recipe for stability, especially in complex systems such as electrical grids, ecosystems, and advanced materials. For years, researchers often worked from the assumption that networks should perform more reliably when their individual parts behave as similarly as possible. Real systems, however, rarely look…

Scientists solve a 50-year mystery and discover a new human blood group

More than half a century after scientists first encountered a mysterious marker on human red blood cells, researchers finally traced it to its genetic source. The breakthrough established MAL as a human blood group system and gave doctors a new way to identify the exceptionally rare people whose blood lacks…

Scientists discover the first diplodocus ever found outside North America

Paleontologists have identified the first known evidence of Diplodocus outside North America, a discovery that changes scientists’ understanding of where the iconic dinosaur lived during the Late Jurassic.

Atrial fibrillation is a common heart rhythm condition in older adults and also affects many people living…

Scientists restore a brain protein and reverse signs of aging in mice

Memory problems, thinning skin, and declining bone mass may seem like separate consequences of growing older. Yet experiments in mice suggest that changes in a protein deep inside the brain can influence all three. Restoring that protein, called Menin, improved several signs of aging, while a separate treatment with the…

Ozempic can change your body. Can it change your life?

GLP-1 medications such as Ozempic have reshaped treatment for Type 2 diabetes.
