Research on carpenter ants provides first example of a non-human animal severing limbs to curb infections

It sounds like a scene from a Spielberg film: an injured worker undergoes an emergency amputation, performed by one of her colleagues, allowing her to live another day. But this is not a human story – it is behaviour seen in ants.

While it is not the first time wound care has been seen in ants, scientists say their discovery is the first example of a non-human animal carrying out life-saving amputations, with the operation performed to treat leg wounds and prevent the onset or spread of infection.

Moss that grows in Mojave desert and Antarctica may help establish life on the red planet, researchers say

While Matt Damon relied on potatoes cultivated in crew biowaste to survive in the hit film The Martian, researchers say it is a humble desert moss that might prove pivotal to establishing life on Mars.

Scientists in China say they have found Syntrichia caninervis – a moss found in regions including Antarctica and the Mojave desert – is able to withstand Mars-like conditions, including drought, high levels of radiation and extreme cold.
