We’re about to unlock the secrets of ancient human brains
For the first time, we have a method for extracting proteins from preserved soft tissues like brains – which could be a treasure trove of evolutionary information
Your imagination doesn’t get worse as you age – but it does change
It’s natural to associate wild flights of fantasy with children and a more mundane internal world with adult life. The latest research, though, shows that isn't the whole picture

Gripping story reveals race to crack world's oldest script, cuneiform
Cuneiform, the oldest identified writing system, defied deciphering – until 1857. What happened then makes a terrific read, in Joshua Hammer's The Mesopotamian Riddle

It’s incredibly tricky to pin down the origin of the language that led to the words spoken everywhere between Spain and India
Where EV batteries go to die – and be reborn
Batteries for electric vehicles are notoriously difficult to recycle, but growing demand for the rare metals they contain is leading to innovative new ways of retrieving them from used power cells
A radical new idea for how our ancestors invented stone tools
Stone tools are considered the first form of technology devised by ancient humans – but they might not have been invented from scratch
Budgie brains have a map of vocal sounds just like humans
Recordings of brain activity in budgerigars reveal sets of brain cells that represent different sounds like keys on a keyboard – a structure never seen before in any bird brain
Ancient face bones offer clues to identity of early humans in Europe
Bone fragments from a cave in northern Spain suggest there were multiple hominin species living in western Europe around a million years ago
