Two brain regions seem to work together to determine whether we are seeing something real, or merely a product of our imaginations - and understanding them further may help treat visual hallucinations

Thousands of tiny nematode worms can join up to form tentacle-like towers that can straddle large gaps or hitch rides on larger animals

The discovery of a Saturn-sized gas giant orbiting a small red dwarf is urging astronomers to reconsider their theories of planet formation. Core accretion theory is the most widely accepted explanation for planetary formation. It describes how planet formation begins with tiny dust grains gathering together and forming planetary cores that grow larger through accretion. It explains much of what we see in our Solar System and others. This discovery introduces some doubt.

As our ancestors developed more advanced tools and cultural practices, they also developed new ways of explaining concepts to others – culminating in the emergence of complex language

Vitamin K is increasingly marketed with Vitamin D. But is this combination evidence-based?

The post Should You Take Vitamin K With Your Vitamin D? first appeared on Science-Based Medicine.

Across the universe, some of the most dramatic events occur when a black hole meets a neutron star. A neutron star is the ultra-dense remains of a massive star that exploded—imagine all the mass of our Sun compressed into a sphere just a few tens of kilometres wide. When a black hole and neutron star spiral toward each other, the result is one of nature's most violent spectacles.

For years, scientists have been scratching their heads over the "Hubble Tension,” the mismatch between how fast the cosmos expanded in its youth versus how fast it's expanding today. But now, armed with the most precise data ever captured by the James Webb Space Telescope, astronomers have found the perceived gap is staring to narrow!I n fact, the expansion rate measured by Cepheid variables versus the cosmic background has overlapping error bars again. Will the tension mystery finally be resolved?

A 500-page proof that only a handful of people in the world claim to understand kicked off a saga unlike anything else in the history of mathematics – and now there’s a new twist to the story, says Jacob Aron

Despite reports of a recent surge in ADHD, a global analysis has found no reliable evidence of an increase in the number of children diagnosed with the condition since 2020

Thanks to AI and modern carbon dating techniques, we have a new understanding of when the Dead Sea Scrolls were written – which could revise the story of Judea

Understanding the meaning of "equals" in mathematics tells us a lot about both the nuance and richness in the field, but also how ideas of equality are used or misused in life

In this latest instalment of Future Chronicles, an imagined history of future inventions, we journey to 2035, when undersea living became a reality. Rowan Hooper tells us how it happened

Feedback is amazed to see sperm racing touted as a new track sport, but it’s going to take a lot of CGI and other fakery to help it take off

Being accurate in the language we use to describe conditions like ADHD matters, and can lead to better outcomes for those affected. The words we choose to use are important, say Alex Conner and James Brown, hosts of podcast The ADHD Adults

A new book on quantum physics is pleasingly full of cutting-edge topics. Yet it isn't the accessible work it promised to be

Putting an end to a mass extinction sounds like an impossible task, but some researchers argue that doing so would be setting our ambitions too low

Astronomers have found another super-Earth. It's about 10 times more massive than Earth, and orbits in the habitable zone of a Sun-like star about 2475 light-years away. These massive Earth-like planets hold key information about how planets form and evolve.
