After record temperatures in 2024, climate scientists had expected this year to be cooler, but instead the planet seems to be heading for a second year above the 1.5°C climate goal

An analysis of compounds in chilli peppers has revealed chemicals that seem to negate their heat-giving capsaicinoids. This explains why the Scoville scale for measuring spicyness isn't always accurate, and could eventually lead to the development of an "anti-spice" condiment

Not knowing how much milk a baby consumes when breastfeeding can cause anxiety for parents, but an innovative device seems to provide objective measurements

A lunchbox-sized radar system could help the FBI detect moving or stationary people by peering through walls via radio waves

Despite setting a global temperature record, 2023 might have been even hotter were it not for the cooling effect of smoke from massive wildfires in Canada

The pitch and hoarseness of a person's voice often changes if they have Parkinson's disease, suggesting there could be a non-invasive way of screening for the condition

Dyson spheres, a type of huge megastructure designed to capture the energy output of a star, would be a sign of an alien civilisation – if we can find one before they disappear

Chinese researchers have a new method to extract uranium from seawater twice as cheaply as previous technologies. Their success comes as China needs uranium to fuel its unprecedented nuclear expansion

While intermittent fasting may be growing in popularity, relatively little is known about how it impacts our gut microbiome – for better or for worse

An AI leaderboard suggests the newest reasoning models used in chatbots are producing less accurate results because of higher hallucination rates. Experts say the problem is bigger than that

Extreme weather events are the most dramatic consequence of climate change, but there are many smaller ways it disturbs our daily life

Kepler's Supernova, seen in 1604, is one of the most famous exploding stars ever seen, and now astronomers think it may have been an interloper from another galaxy

Just like humans, chimps have rhythm when drumming, which suggests that the trait evolved in our common ancestor

Our bodies emit a stream of low-energy photons, and now experiments in mice have revealed that this ghostly glow is cut off when we die
