Nearly half of Americans dont know that processed meat increases colorectal cancer risk, according to a new poll. But once they learn the connection, most support warning labels-suggesting people want clearer information...

Researchers have identified brain circuits in the central amygdala that decide whether an animal freezes or flees. The study shows that "unlearning" fear is actually a process of recalibrating these circuits, off...

A new meta-analysis reveals no link between hormonal contraception and idiopathic intracranial hypertension (IIH). The findings offer reassurance to women using birth control, as the study found no increased risk across ...

When temperatures plunge, the risk to your heart rises dramatically. A large U.S. study shows cold weather is linked to far more cardiovascular deaths than heat, accounting for tens of thousands of extra deaths each year...

In a landmark trial, social media giants Meta and YouTube were found negligent and ordered to pay for harming a user's mental health. The decision could force major changes in how social platforms work

Researchers have shown that the primary visual cortex (V1) computes statistical summaries of complex motion, such as mean and variance. This "ensemble perception" starts early in the visual hierarchy, allowing th...

A massive study of 700,000 people shows that ADHD medication in childhood does not increase the risk of psychosis. In fact, starting treatment before age 13 may help protect against schizophrenia in adulthood.

Their mass is extremely low, but how light are neutrinos really? A collaboration comprising German and international research groups has optimized its experiments to determine the mass of these "ghost particles."...

A new study using data from China's Chang'e-4 moon lander found an area of reduced radiation from cosmic rays near the moon. The findings could be used to improve the safety of lunar explorations.

Shortlisted for the Sony World Photography Awards, this image by photographer Sebastian Di Domenico was taken in Columbia

Feedback is prompted by readers to investigate the size of the shed in the term 'shedload', and gets down and dirty with particle physics in the quest

We shouldn't dismiss flowers as merely ornamental - these blooms are world-changers, argues a vivid new book by David George Haskell. Michael Marshall is mostly convinced

NASA's Gateway lunar space station won't launch next year in new changes to the Artemis program, which include ramping up development of a $20 billion moon base and a nuclear-powered 'Freedom' spacecraft....

Researchers have discovered the molecular pathway connecting the gut immune system to the brain. By mapping how tuft cells signal the vagus nerve, the study explains why parasitic infections and gut issues cause a linger...

Caltech scientists have developed a new way to produce optical frequency combs-important tools in devices that keep time and measure distances very precisely-at the chip scale, an advance that should make it easier to in...

A duo of drugs that boosts our glympathic system, which clears waste from our brain, also improves the removal of proteins associated with the onset of Alzheimer's disease

Scientists have mapped the atomic movement of TRPM8, the protein that senses cold and menthol. This "molecular movie" reveals how lipids lock the protein open, providing a new target for treating cold-induced pai...

Phonons are the quantum units of mechanical vibration. They describe how motion propagates through a solid at the smallest possible scales, in much the same way that electrons describe electric currents. Because phonons ...

What causes "Brain on Fire" syndrome? A new study links anti-NMDA receptor encephalitis to the body's natural defense against breast cancer.

The remains of dogs from more than 14,000 years ago have been found in Turkey and the UK, revealing that domesticated animals were spread across Europe by hunter-gatherers

The same principles that help astronauts stay strong in microgravity can help us all resist the slow collapse of ageing - and its not all about hitting the gym more

For decades, it has been widely believed that electrons move most efficiently in materials that are clean and highly ordered. Much like water flowing more easily through a smooth pipe, conventional wisdom has held that e...
