It sounds like something dreamt up by a science fiction writer, but scientists have created a walking 'bio-bot' made from rat heart cells and hydrogels, using a 3-D printer.
Our ancestors were attaching spear points to wooden hafts as long ago as 500,000 years - a good 200,000 years earlier than thought.
Scientists from the University of Arizona have released a video of the leggiest animal on Earth, the millipede Illacme plenipes, which has 750 legs.
The great white shark isn't descended from megatooth sharks such as the extinct Carcharocles megalodon - the largest carnivorous shark that ever lived - as many believed.
Scientists say they've identified a crucial gene, unique to humans, that may help explain how we learned to use tools and language.
Our early ancestors in Central Africa, between three million and 3.5 million years ago, munched mainly on tropical grasses and sedges - a much earlier change in diet than previously believed.
In a blow to the highly-popular theory of supersymmetry, scientists at the Large Hadron Collider (LHC) at CERN have spotted one of the rarest particle decays ever seen in nature.
A new study suggests that humans may be (slowly) losing our intellectual and emotional abilities because they're at risk from mutation or loss from the genome.
The CERN supercollider could become the world’s most precise stopwatch, thanks to a new method of keeping time devised by researchers at Vienna University of Technology (TU), Austria.
Before DNA became Earth's primary genetic material, early forms of life are believed to have used RNA to encode genetic instructions. But what was doing the job before RNA came on the scene?
Scientists say they've - rather belatedly - identified a completely new type of large, horned dinosaur after re-examining fossils originally collected in 1958.
The near-complete remains of a woolly mammoth skeleton have been discovered on the banks of the river Marne near Paris, France.
Decades of extreme weather first weakened the Mayan culture and then killed off much of the population.
Coffee-lovers take note; climate change could put an end to your daily Starbucks, a new study has found.
The giant pterosaur Quetzalcoatlus needed to taxi down a slope to take off, new research shows.
Researchers from the Netherlands and Italy have succeeded in making sharp pictures of objects hidden behind an opaque screen.
The first modern humans may have evolved on the south coast of South Africa, where they were making and using stone weapons far earlier than previously believed.
It could be possible to get advance warning of volcanic eruptions by observing them from space.
After 30 years of debate, scientists believe they've discovered the trigger for the last great freeze of the Earth, some 12,900 years ago.
A captive cockatoo has been observed spontaneously making tools to get at food - the first time any type of parrot's been seen to do this.
