Solar cells offer the opportunity to harvest abundant, renewable energy. Although the highest energy light occurs in the ultraviolet and visible spectrum, most solar energy is in the infrared. There is a trade-off in harvesting this light, so that solar cells are efficient in the infrared but waste much of the energy available from the more energetic photons in the visible part of the spectrum.
Researchers have created a new type of transparent electrode that might find uses in solar cells, flexible displays for computers and consumer electronics and future "optoelectronic" circuits for sensors and information processing.
Scientists have created a free-swimming 'jellyfish' out of silicone seeded with living heart muscle cells.
Scientists say they've identified 'internal compass needles' in the noses of rainbow trout, helping explain the way many creatures can navigate using the Earth's magnetic field.
Harvard researchers have created a tiny 'DNA robot' that can seek out and destroy specific cells - including cancer cells.
A team at at the Technische Universitaet Muenchen says it's built the foundation for devices to communicate directly with the human brain.
An international team of scientists has embarked on an ambitious research project to develop an in vivo biological cell that can be reprogrammed like a computer operating system.
Since 2007, researchers at the U.S. Department of Energy's BioEnergy Science Center (BESC) at Oak Ridge National Laboratory have been looking for ways to make cost-effective biofuels from nonfood "cellulosic" plant fibers.
Scottish scientists say they've taken the first steps towards creating a form of life based on inorganic elements.
A group of security researchers has pointed out in a paper that software vulnerabilities could allow criminals to spring prisoners from their cells.
Anonymous says Italian cells associated with the collective remain intact - even after local law enforcement officials arrested a number of cyber activists linked to the group.
Scientists at the Wake Forest Center for Regenerative Medicine have created a way of - literally - printing skin cells onto burn wounds.
