S.Africa ideal for world's largest telescope: minister
South Africa is well-placed to host the world's largest telescope because the costs would be lower, according to the deputy science minister.
Research may yield more compact antennas for military use
(PhysOrg.com) -- While tall, bulky antennas seem like relics in an era of sleek, modern smartphones, they're still an unfortunate necessity for American soldiers.
Making a light-harvesting antenna from scratch
(PhysOrg.com) -- Sometimes when people talk about solar energy, they tacitly assume that we're stuck with some version of the silicon solar cell and its technical and cost limitations. Not so.

An asteroid the size of an aircraft carrier is set to make a close but harmless swing by Earth on Tuesday.
Biologists identify light-regulated mechanism in cyanobacteria as aid to optimizing photosynthesis
(PhysOrg.com) -- Indiana University biologists have uncovered how a control system works in producing the important light-harvesting antennae that power photosynthesis in cyanobacteria, the microorganisms ...
Putting light-harvesters on the spot
How the light-harvesting complexes required for photosynthesis get to their site of action in the plant cell is reported by RUB biologists in the Journal of Biological Chemistry. The team led by Prof. Dr. Danja Schunemann has de ...
New glass stamp may make cheaper, more precise biosensors
Advances in microchip technology may someday enable clinicians to perform tests for hundreds of diseases -- sifting out specific molecules, such as early stage cancer cells -- from just one drop of blood. ...
