Palaeontologists have discovered a remarkable new 506-million-year-old predator from the Burgess Shale of Canada. Mosura fentoni was about the size of your index finger and had three eyes, spiny jointed claws, a circular mouth lined with teeth and a body with swimming flaps along its sides. These traits show it to be part of an extinct group known as the radiodonts.

Originally from South America, the charismatic tegu made its way to the United States via the pet trade of the 1990s. But a recent discovery shows these reptiles are no strangers to the region -- tegus were here millions of years before their modern relatives arrived in pet carriers.

Scientists have discovered fossil evidence of an endangered, living tropical tree species. The unprecedented find was made in Brunei, a country on the large island of Borneo, and reveals a critical piece of the ancient history of Asia's rainforests, highlighting the urgent need for conservation in the region, according to researchers.

Modern HIV medicine is based on a common genetic mutation. Now, researchers have traced where and when the mutation arose -- and how it protected our ancestors from ancient diseases.
The Arctic landscape during the Cretaceous Period may have been dominated by the dinosaurs, but the rivers and streams held something more familiar. Alaska's fresh waters 73 million years ago were teeming with the ancient relatives of today's salmon, pike and other northern fish. A new article has named three new species of fish from that time period, including a salmonid, dubbed Sivulliusalmo alaskensis.

Just like humans, chimps have rhythm when drumming, which suggests that the trait evolved in our common ancestor
Our bodies emit a stream of low-energy photons, and now experiments in mice have revealed that this ghostly glow is cut off when we die
With season 2 unfolding, the science of the fungal horror drama is becoming shakier. It is a pity that the creators haven’t thought about terrifying scenarios of real-life infection, says Corrado Nai
In this latest instalment of our speculative column Future Chronicles, an imagined history of future inventions, Rowan Hooper explores the pros (and cons) of networking our brains with those of other animals
Newly discovered species of extinct fish shows striking similarities to unrelated modern-day predators, suggesting certain traits have emerged multiple times and remained consistent over hundreds of millions of years.

Life depends on genes being switched on and off at exactly the right time. Even the simplest living organisms do this, but usually over short distances across the DNA sequence, with the on/off switch typically right next to a gene. This basic form of genomic regulation is probably as old as life on Earth. A new study finds that the ability to control genes from far away, over many tens of thousands of DNA letters, evolved between 650 and 700 million years ago. It probably appeared at the very dawn of animal evolution, around 150 million years earlier than previously thought. The critical innovation likely originated in a sea creature, the common ancestor or all extant animals.
Superb starlings appear to swap between parent and ‘nanny’ roles to help raise chicks over their lifetimes, even when they aren’t related to them
The origin of complex eukaryotic cells, of the type found in all plants and animals, is shrouded in mystery. Now, strange microbes from wetlands in China are helping us to understand when they first emerged, and what they were like
A UK parliamentary committee has greenlit gene-edited plants. This is great news, as it will boost food production and reduce waste, says Michael Le Page
