Candida auris is a relatively new addition to a family of fungi that can infect people. Most of these infections occur in sick, hospitalized patients and can be deadly.
Older monkeys still hang out, just with a smaller circle of intimates.

Many older people tend to trim their social circles and focus their social efforts on family and close friends. New research on our close primate relatives may help explain why.
Human evolution is typically depicted with a progressive whitening of the skin, despite a lack of evidence to support it.

From Aristotle to Darwin, inaccurate and biased narratives in science not only reproduce these biases in future generations but also perpetuate the discrimination they are used to justify.
Mammals have evolved flight more often than birds. By studying the genes of the sugar glider, biologists have found a ‘molecular toolkit’ for flight membranes that’s been in us all along.
Unravelling the mystery of how life in Antarctica survived past ice ages involved sampling some of the oldest museum records. When combined with a dating database, a familiar story is revealed.
A wonky skull. Enlarged ear chambers. Asymetrical ears. It looks like the elusive night parrot has traded off vision for excellent hearing

Antarctic minke whales are elusive and hard to track – but a new study of their behaviour offers clues to their evolution and the limits of their filter-feeding behaviour.
To test the ballistic properties of the stone points found in the Mandrin cave, modern duplicates were created and hafted on to shafts, as they may have been 54,000 years ago.

In 2022 we detailed the discovery of 1,500 stone points in France’s Madrin cave. Experiments now show that they could were used as arrowheads, pushing back evidence of archery in Eurasia by 40,000 years.

New research provides insights into the evolution and ecology of Australian bees. The capricious masked bee employs female nest guards in a cooperative social structure. Meanwhile, fussy feeders abound.

A local legend of a mysterious bird with big eyes grew into the discovery of the Príncipe scops owl. A biologist on the team tells the story of finding and cataloging this new species.
Your brain can imagine things that haven’t happened or that don’t even exist.

By learning what parts of the brain are crucial for imagination to work, neuroscientists can look back over hundreds of millions of years of evolution to figure out when it first emerged.
