In 1997, scientists announced they’d created a healthy sheep cloned from another ewe’s mammary gland cell. Two decades on, the technique is being refined and applied to new challenges.

During bird irruptions, hundreds or thousands of a single species show up outside their normal territory. Most of what we know about irruptions comes from data collected by citizen scientists.
It’s estimated our cells will replicate 10,000 trillion times in our lifetime. Errors in this process can lead to cancer.

Victorian attitudes influenced what scientists thought they were observing about sexual behaviors in the animal world. But modern techniques reveal the myth for what it is.
Four organisms that show nature isn’t so easily categorised.

When art meets the biological sciences, living matter becomes the medium. From the chaotic beauty of smallpox to poems implanted in bacteria, Bio-art investigates the boundaries of life and death.
A new exhibition at MONA, curated by scientists, explores the biological and evolutionary origins of art. The show is spectacular - but it offers an overwhelmingly male perspective.
Too good to be true? Time to hair the evidence!

Humans can more easily tolerate tumours in large or paired organs than in small, critical ones. This could be why the latter have evolved more cancer-fighting mechanisms.
Do you know your parasites from your gut commensals? Read this and you will.
The “Roman” nose, such as the Colossus of Constantine (from c. 312–315 AD), has been a target of both admiration and abuse.

Scientists uncover hidden mathematical structures controlling how living cells operate. If this could be used by computers of the future, we may one day be able to understand the brain.
Look beyond transgenic techniques that add new genes to a species. People have used selective breeding techniques to change plants and animals for millennia – why not try them on mosquitoes?
