Anthropologist Christopher Bae has recently suggested we add two new species of ancient human to our family tree. The plans break the conventions for how species should be named – but Bae argues the rules themselves are flawed

There are now over 10,000 satellites in orbit, more than at any point in history, and this growing number is starting to reveal how solar storms could disrupt internet mega constellations like SpaceX's Starlink

All over the world people are ageing more rapidly and succumbing to diseases that typically affected the elderly. But there are ways to turn back the clock on your biological age

The very first generation of stars, called Population III stars, are mostly expected to be too distant to see directly – but astronomers may have found some for the very first time

For the first time, video footage has captured orcas in the Gulf of California hunting young great white sharks, using a trick to flip them over, paralise them and get at their energy-rich livers

The uncertainty inherent to quantum mechanics has long left physicists wondering whether the observations we make on the quantum level reflect reality - a new test suggests they do

We now have only the second high-quality genome from an ancient Denisovan human, which reveals there were more populations of this species than we thought

A sheet of fabric that is three times stronger than Kevlar could stop a bullet despite being just 1.8 millimetres thick, thanks to the addition of carbon nanotubes that keep its molecules aligned

Existing tools that work out the carbon footprint of flights greatly underestimate their warming impact, say the makers of a new calculator
