A ‘one of a kind’ fossil discovery could transform our understanding of how the unique brains and intelligence of modern birds evolved, one of the most enduring mysteries of vertebrate evolution.

Researchers have developed a machine learning algorithm to accurately detect heart murmurs in dogs, one of the main indicators of cardiac disease, which affects a large proportion of some smaller breeds such as King Charles Spaniels.

Researchers have discovered that seabirds, including penguins and albatrosses, have highly-sensitive regions in their beaks that could be used to help them find food. This is the first time this ability has been identified in seabirds.

Butterfly populations in northern Spain are better than their UK counterparts at regulating their body temperature, but rising global temperatures may put Spanish butterflies at greater risk of extinction.

The tale of two charismatic species cooperating for mutual benefit has captivated naturalists for centuries – but evidence has been patchy. Researchers have now carried out the first large-scale search for evidence.

Fossil bones from two newly-described penguin species, one of them thought to be the largest penguin to ever live – weighing more than 150 kilograms, more than three times the size of the largest living penguins – have been unearthed in New Zealand.

Fossilised fragments of a skeleton, hidden within a rock the size of a grapefruit, have helped upend one of the longest-standing assumptions about the origins of modern birds.

An asteroid strike 66 million years ago wiped out the non-avian dinosaurs and devastated the Earth’s forests, but tree-dwelling ancestors of primates may have survived it, according to a new study published in the journal Ecology and Evolution.

Should we be concerned about the coronavirus spreading to cats? Not yet, says Dr Sarah Caddy in this article for The Conversation, even after a concerning report from Belgium.

Researchers have shown how millions of years of climate change affected the range and habitat of modern birds, suggesting that many groups of tropical birds may be relatively recent arrivals in their equatorial homes.
