Others experience side effects that make existing medications difficult to take. Researchers at the University of…

A mysterious 4,000-year-old wall is rewriting North Africa’s history

In the hills of north-west Morocco, overlooking the river that gives the site its name, research at Oued Beht is bringing to light a previously unknown chapter of the region’s past. The discovery of a substantial built structure suggests that, during the second millennium BC, communities in north-west Africa were…

Scientists discover metals that defy the deep freeze at -424°F

Scientists have uncovered an unexpected way certain metals can withstand extreme cold without becoming dangerously brittle. The discovery challenges long-standing ideas about how metals behave at extremely low temperatures and could help engineers develop tougher materials for some of the harshest environments imaginable. The findings, published October 14 in Nature,…

75,000-year-old Neanderthal may have been killed by a spear aimed at the heart

A small, circular hole in a 75,000-year-old Neanderthal shoulder blade may reveal one of the earliest known cases of deadly violence involving a wooden spear. The remarkable discovery, made in a cave in Iraqi Kurdistan, suggests that the individual was struck by a sharpened wooden weapon that passed through the…

Scientists discover a bacterial defense so strange they thought it was broken

Scientists at Gladstone Institutes have discovered an unusual bacterial immune system that operates in almost the opposite way of previously known defenses. The surprising mechanism allows bacteria to activate a deadly self-destruct process when viruses attack, potentially offering new ideas for developing medical treatments and gene-editing technologies. The findings, published…

A surprising vitamin A discovery is changing what scientists know about vision

Scientists at Johns Hopkins University have uncovered a surprising role for a vitamin A derivative in the development of human vision. Their research reveals how this molecule works alongside thyroid hormones to help form the part of the eye responsible for our sharpest sight, challenging a scientific explanation that has…

Scientists smash oxygen nuclei to recreate matter from the Big Bang

New findings from the STAR experiment at the Relativistic Heavy Ion Collider (RHIC) suggest that scientists can recreate an extraordinary form of matter from the earliest moments of the universe using surprisingly small atomic collisions. By smashing oxygen nuclei together at nearly the speed of light, researchers have uncovered strong…

A simple blood test could reveal Alzheimer’s risk 10 years before symptoms

A simple blood test could help identify people at increased risk of Alzheimer’s-related cognitive decline years before they experience any noticeable problems with memory or thinking. In a large international study, researchers found that older adults with very high levels of a particular blood biomarker faced a 38% chance of…

Type 2 diabetes breakthrough as 54% achieve remission in just 6 months

A carefully structured combination of diet and exercise may offer a powerful way to put type 2 diabetes into remission in younger adults. In a new clinical trial, more than half of participants who followed an intensive lifestyle program achieved remission within just six months, compared with only 4% of…

Physicists created a tiny universe and watched time emerge without a clock

What if time is not a fundamental part of the universe, but something that emerges from the changes taking place inside it? A physicist at the University of Birmingham has created a miniature universe in the laboratory that offers a surprising new way to investigate this possibility. Using thousands of…

The asteroid killed the dinosaurs. Why did crocodiles survive?

Why did crocodiles survive the asteroid impact that wiped out the dinosaurs 66 million years ago? New research suggests that their preference for warm environments may have given them a crucial advantage during one of Earth’s greatest mass extinctions. Scientists led by UCL (University College London) found that crocodiles and…

A computer scientist breaks through a limit that stood since 1996

Finding the shortest route between two locations is something navigation apps like Google Maps do every day.

An international research team, including astronomers…

Scientists reveal a hidden snakebite crisis killing up to 513,000 people a year

Not every snakebite injects venom. When venom enters the body, however, it can cause snake envenoming. This is a potentially fatal condition and it mostly affects poor rural communities across tropical and subtropical regions who don’t have easy access to medical care. As researchers with decades of combined experience in…

Why some “lower-risk” childhood cancers turn deadly

Some childhood cancers may be far more dangerous than their initial risk classification suggests. Scientists have discovered that certain tumors considered less threatening can contain hidden populations of highly aggressive cancer cells, potentially explaining why some children experience devastating outcomes despite lacking the usual genetic warning signs. The discovery could…
