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.

Scientists read a mouse's mind

Stanford scientists have found a way of observing real-time brain activity in a live mouse, letting them work out where the mouse is in an enclosure on the basis of which neurons are firing.

Meerkat bosses use subordinates as guinea pigs

Just as ancient emperors employed tasters to make sure their food was harmless, so meerkat 'queens' use more junior members of the group as guinea pigs.

Intact biomolecules found in 350-million-year-old fossils

Excessive TV in childhood blamed for long-term antisocial behaviour

New Zealand researchers have published a study claiming that children and adolescents who watch a lot of television are more likely to manifest antisocial and criminal behaviour when they become adults.

Advanced "smart materials" found in 2014 Corevette

The engineering and technology found in the upcoming 2014 Chevrolet Corvette is quite impressive.

Bilingual babies learn grammar by seven months

Babies can distinguish between, and begin to learn, two languages with vastly different grammatical structures at just seven months old, say scientists.

How artificial platelets could help treat soldiers on the battlefield

When it comes to healing traumatic wounds of war, success may hinge on the first blood clot – the one that begins forming on the battlefield right after an injury.

NASA: Meteor explosion in Russia had nothing to do with asteroid flyby

The scientific community is aflutter after reports, images, and video of a massive meteor explosion in Russia clogged the Internet early Friday morning.

Single mutation brought many East Asian traits

A single mutation around 30,000 years ago appears to be responsible for several traits common in East Asian peoples, from thicker hair to denser sweat glands.

Dogs recognize other dogs on a computer screen

Dogs can pick out faces of other dogs on a computer screen, say researchers, irrespective of breed, showing they can recognize and categorize their own species by sight alone.

Methane explosions power these soft jumping robots

Harvard researchers are currently devleoping "soft robots" that are capable of performing all sorts of functions robots made out of rigid materials, such as metal, are unable to do.

Video: Sixth sense rats touch the infrared light

Researchers at Duke University have managed to develop an experimental prototype that allows rats to "touch" invisible infrared light.

Microsoft's Kinect tapped for remote medicine

Researchers at the University of Arkansas at Little Rock claim that Microsoft's Kinect game controller could cut the US healthcare bill by up to $30 billion - by allowing physicians and other medics to remotely interact with patients.

Video: This biodiesel plant sits in your kitchen

I love eating bacon, but hate making it. Not only does that smell seem to permeate every inch of the house for hours after, but there’s always the question of what to do with the leftover grease.
