Cavities could be prevented by a gel that restores tooth enamel
Enamel does not naturally regenerate, which can lead to painful cavities, but a gel that harnesses some of the properties of saliva could restore the hard, shiny layer to teeth

Walking 3000 steps a day seems to slow Alzheimer's-related decline
Alzheimer's-related cognitive decline could be slowed by taking as few as 3000 steps a day, possibly due to the effects of regular exercise on brain health

Antarctic glacier's alarming retreat is the fastest ever seen
Hektoria glacier on the Antarctic Peninsula retreated 25 kilometres in just 15 months. Its rapid melt could have implications for other glaciers and the rate of sea level rise

Does the family tree of ancient humans need a drastic rewrite?
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

Orcas are ganging up on great white sharks to eat their livers
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
