Animal science

What naked mole-rats lack in the looks department they make up for it in longevity, living healthily for nearly four decades. Now, scientists have found just how they repair their DNA – and it has the potential to be harnessed by humans to do the same.

This year’s Bird Photographer of the Year competition attracted more than 33,000 entries from across the globe, which ultimately delivered a 2025 winners’ list that captures the beauty, drama and diversity of winged wildlife at its best.

Following on from last year's 34th First Annual Ig Nobel Prize, the 35th First Annual Ig Nobel Prize night took place at Boston University this week, celebrating the joy of science: Real research with some delightfully sideways paths of investigation.

A skull found on a UK beach has rewritten the history of lizards, snakes and the tuatara, the last survivor of an ancient lineage found only in New Zealand today. The new species dates back 242 million years, making it the earliest known lepidosaur.

We don't fully understand why some people are more attractive to mosquitoes – it's a complicated web of physiological and bacterial factors, geography and species. But a new study suggests that some insects like to home in on the life of the party.

Australia's embattled koalas have been given some good news for once, with the approval of the world's first chlamydia vaccine. More than a decade in the making, a single jab will now protect koalas from the disease decimating their populations.

In the largest study of its kind, scientists have documented the seismic shift in animal size over the last 1,000 years, with domesticated species becoming larger as wildlife gets smaller. It underlines the impact of one species in particular – us.

Right now, groups of Icelanders are taking to the streets late at night, armed with cardboard boxes and torches, in search of the white bellies of baby puffins. This annual tradition has become one of the most fascinating rescue missions on the planet.

Unearthed in southern Patagonia, a remarkably intact skeleton has been found to be a new species of crocodyliform: A fearsome hypercarnivore that roamed the Earth 70 million years ago, using its blade-like teeth to tear up pray – including dinosaurs.

A groundbreaking study has traced the 66-million-year history of primates to overturn conventional thought that our ancestors came from tropical forests. The earliest members of our family tree, scientists say, were actually cold-climate survivors.

Leopard seals may be one of Antarctica’s most fearsome predators, but these vocalizers sing with the structured charm of a nursery rhyme. In a new study, researchers discovered that the underwater vocal patterns of these mammals resemble human song.

They’ve been crawling across the seafloor for 500 million years, but some sea stars have amassed such a population they're eating entire reefs alive. Now, a discovery about their spine-speaking chatline gives us a leg up in this ecological arm's race.
