The same cells electric eels use to shock predators and prey could be engineered to power implanted biomedical devices, say US researchers.
Couples struggling to conceive should move their focus out of the bedroom and on to the beach, new fertility research suggests.
The basic technology used in cheap 3D postcards and novelty items has been adapted to create six-dimensional images that respond to changes in light and the viewer's direction.
Scientists have created two new types of materials that can bend light the wrong way, creating the first step toward an invisibility cloaking device.
A pair of British researchers has come up with a theory of how to design a material that would help you avoid detection by making light reflect back towards the viewer.
UK researchers have created a tiny liquid crystal display using a transparent material harder than diamond and only one atom thick.
NEWS ANALYSIS: We can send probes to the fringes of the solar system. Swap instant messages with friends on the other side of the world. Conduct surgery by remote control over the internet. So surely we have some hi-tech help for the hundreds of thousands of people in Burma and China who are walking on the tightrope of death. Right?
US scientists have customised nanoengines by spiking the gas with rocket fuel and adding carbon nanotubes to strengthen the motor's microsized frame.
Australian researchers hope to insert plant and insect genes into crops to 'farm' industrial chemicals including super-lubricants, adhesives, sensors, antibacterials and stretch-Kevlar.
The Iraq war has triggered a massive injection of US government funds to fast-track efforts to grow replacement ears, noses, limbs, skin, muscles and other body tissue.
