Secret of efficient photosynthesis: Purple bacteria's light-harvesting prowess lies in highly symmetrical molecules
Purple bacteria are among Earth's oldest organisms, and among its most efficient in turning sunlight into usable chemical energy. Now, a key to their light-harvesting prowess has been explained through a detailed structural ...
New technique allows closer study of how radiation damages materials
A team of researchers led by North Carolina State University has developed a technique that provides real-time images of how magnesium changes at the atomic scale when exposed to radiation. The technique ...
Shear stiffness and friction mechanics of single-layer graphene measured for the first time
Researchers from the University of Bristol have measured and identified for the first time the stress and strain shear modulus and internal friction of graphene sheets. Graphene is a material that has many ...
Revealed: Secret of bees' honeycomb
For thousands of years, thinkers have marvelled at the feat of engineering that is the honeycomb.
California's Channel Islands hold evidence of Clovis-age comets
A 17-member team has found what may be the smoking gun of a much-debated proposal that a cosmic impact about 12,900 years ago ripped through North America and drove multiple species into extinction.

Fluid clue to Saturn's hexagon (w/ Video)
(PhysOrg.com) -- An unusual hexagonal structure found in Saturn's atmosphere has been recreated in an Oxford laboratory.
Spheres can form squares
Everybody who has tried to stack oranges in a box knows that a regular packing of spheres in a flat layer naturally leads to a hexagonal pattern, where each sphere is surrounded by six neighbours in a honeycomb-like ...
Development of Euglena-based bioplastics
Researchers from AIST have developed microalga-based bioplastics mainly from constituents extracted from Euglena, a species of microalga.
