The oldest protein fragments ever recovered have been extracted from fossilised teeth found in Kenya's Rift Valley, revealing the remains belonged to the ancient ancestors of rhinoceroses and elephants

It’s easy to sneer at people who say they’ve fallen in love with ChatGPT. But we've been developing confusing feelings for bots for decades longer than you might think, writes Alex Wilkins. With so many people feeling lonely, can that be a good thing?

After a controversial project claiming to have resurrected the dire wolf, Colossal Biosciences has now announced plans to bring back nine species of the extinct moa bird

Maintaining good overall health is key to living a long life, but we may want to particularly focus on the state of our brain and immune system

We now have the ability to rapidly assess the death toll of climate change after extreme heat – a first-of-its-kind analysis has shown that it nearly tripled the death toll from the most recent European heatwave

A cancer-killing virus could soon be approved for use after shrinking tumours in a third of people with late-stage melanoma

Interest in the anti-parasitic drug ivermectin skyrocketed during the covid-19 pandemic, but evidence for many of its supposed health claims are lacking

The “One Big Beautiful Bill” just signed by President Trump will slash support for clean energy, leaving the US far short of its Paris Agreement pledge

Ancient humans in Africa changed their behaviour in a major way 70,000 years ago, which could explain how their descendants managed to people the rest of the world

Putting aerosols in the stratosphere to reflect sunlight could prevent the shutdown of key ocean currents, but only if it is done soon, a computer model suggests

Ordering takeaway food, writing emails, reworking presentations: AI assistants are promoted as a way of outsourcing mundane tasks to free up your time for more interesting pursuits. So, what are they actually good for – and what are the risks?

The loss of snow cover in temperate forests is set to slow their growth and reduce their ability to remove carbon from the atmosphere, an overlooked consequence of climate change

Some numbers are so unimaginably large that they defy the bounds of modern mathematics, and now mathematicians are closing in on a number that may mark the edge of this bizarre abyss

Suddenly feeling old? Evidence now suggests that rather than a long, steady decline, we dramatically age around three specific times in our lives. Might it be possible to stay younger for longer?

Around seven asteroids or comets are thought to hit Saturn every year, but we have never spotted one in the act. Now, it seems one astronomer may have caught the moment of impact and the hunt is on for other images to verify the discovery

Drugs and explosive chemicals are difficult to detect, but a device more sensitive than a dog’s nose can pick up their traces in seconds

Computers can help ensure that mathematical proofs are correct, but translating traditional maths into a machine-readable format is an arduous task. Now, the latest generation of artificial intelligence models is taking on the job, and could change the face of maths research

The skull of a 5-year-old girl who lived 140,000 years ago has similarities with modern Homo sapiens and Neanderthals, suggesting her parents might have belonged to different species

Some carbon dioxide absorbed by fig trees gets turned into calcium carbonate within the wood and the surrounding soil, ensuring that the carbon is kept out of the air for longer
