A white dwarf is usually thought of as the quiet remnant left behind after a star has exhausted its fuel and shed much of itself into space. By that stage, any worlds that once orbited nearby are expected to have faced a violent fate. Yet one planetary system roughly 80 light-years from Earth appears to…

Some tropical Heliconius butterflies have evolved a remarkable way to stay young, allowing them to live far longer than most butterflies. Most butterflies survive for only a few weeks after reaching adulthood. But scientists have now identified a group of tropical butterflies that can live for almost a year while showing little sign of physical…

For decades, Antarctica has been treated as a kind of frozen time capsule, a place where evidence of Earth’s deep past sits preserved, undisturbed, beneath layers of ice that have built up over millions of years. As per the study published in Nature Geoscience, scientists have now uncovered something remarkable within that buried record: an…

A colleague’s promotion, a friend’s holiday, a stranger’s fitness progress online, each one quietly resets the bar you are judging yourself against. Sigmund Freud, the founder of…
Freshwater ecosystems have spent years under growing pressure from pollution, changing weather patterns and rising temperatures. Rivers and lakes in many parts of the world have been losing dissolved oxygen, placing fish, aquatic plants and countless smaller organisms under increasing strain. That broader pattern has often been presented as one of the more difficult environmental…
