Yeti helps out polar explorers

If you need help in snow and ice, who better to ask for help than a yeti?

Ancient crocs swam to North America

Relatives of the alligator made it to North America ten million years earlier than mammals, swimming there more than 19 million years ago.

Water vortex ties itself in a knot

Tying a smoke ring in a knot sounds impossible - but University of Chicago physicists have done something similar by creating a vortex knot for the first time, in a container of fluid.

Schrödinger's Cat could be visible after all

Schrödinger's Cat could be (almost) as easy to observe as the internet's millions of LOLcats, with confirmation that there may be a way round Heisenberg's famous Uncertainty Principle after all.

Ancient croc snacked on baby dinosaurs

A South Dakota scientist has discovered a new species of dinosaur - and found that its babies were the meal of choice for a type of crocodile.

Frankenstein tadpoles see with eyes on their butts

In a deeply weird experiment, scientists have transplanted eyes onto the rear ends of tadpoles, and discovered that they can still see.

New features found in one of Earth's earliest animals

A lucky find has allowed scientists to identify one of the earliest evolutionary examples of limbs used for feeding, along with the oldest nervous system to stretch beyond the head in fossil record.

ESA picks target asteroid for spaceship crash

ESA’s planning to crash a spacecraft into an asteroid called Didymos, to, well, see what happens.

CAT scans reveal fossil's spiral teeth

Using CAT scans, Idaho State University researchers have made 3D virtual reconstructions of the jaws of the ancient spiral-toothed fish Helicoprion.

3D holography technique lets firefighters see through flames

An Italian team has developed a new infrared holography technique that allows firefighters to see through flames and find people trapped inside burning buildings.

Chimps like brain-teasers too

Just as you or I might enjoy doing a crossword puzzle, so too do chimps enjoy completing tricky puzzles, just for the hell of it.

Humans have unique brain structures

Humans have at least two functional networks in their cerebral cortex that aren't found in rhesus monkeys, and which appear to be unique.

Lost continent identified in Indian Ocean

The holiday islands of Reunion and Mauritius are all that remains of a small continent that's been hidden under lava for millions of years.

Planetary particle detector could help find 'fifth force'

Physicists say it's possible to use the whole earth as a particle detector, to look for evidence of the mysterious 'fifth force'.

Flowers use electrical signals to summon bees

Flowers 'advertise' the presence of nectar to bees using electrical signals, say University of Bristol researchers, by indicating whether they've recently been visited by another bee.

Mozzies learn to ignore DEET

The insect repellent DEET is nowhere near as good at repelling mosquitoes as believed, says researchers, with mosquitoes learning to ignore it after just a few hours of exposure.

3D printer used to build functioning ear

Cornell bioengineers and physicians have created a fully-functioning artificial ear, using 3D printing and injectable molds.

How mutants save a species

There's one obvious reason why it's easier for a species to survive a gradual environmental change than a sudden one: more individuals stay alive when change is gradual or moderate, meaning there are more chances for a winning mutation to emerge.

This bionic prosthetic hand can feel

The typical prosthetic limb is a very limited device that usually looks very little like the arm, hand or leg it is meant to replace.

Evolution 'surprisingly predictable', says team

Scientists have shown that similar - or even identical - mutations can take place in completely separate populations of E. coli evolving in different environments over more than 1,000 generations.
