Researchers explore Li-air battery reversibility on the nanoscale
In world's first, atomic force microscope sees chemical bonds in individual molecules (w/ video)
(Phys.org)—IBM scientists have been able to differentiate the chemical bonds in individual molecules for the first time using a technique known as noncontact atomic force microscopy (AFM).
Nanotube-based sensors can be implanted under the skin for a year
Nitric oxide (NO) is one of the most important signaling molecules in living cells, carrying messages within the brain and coordinating immune system functions. In many cancerous cells, levels are perturbed, ...
New study suggests Neanderthals died out earlier, did not coexist with modern humans
Theories about when the last Neanderthals walked the Earth may have to be revised, according to a study that suggests they became extinct in their last refuge in Spain much earlier than previously thought.
Century-old chemistry problem solved
Chemists at The Scripps Research Institute (TSRI) have found a way to apply a "foundational reaction" of organic chemistry to a stubborn class of chemicals, in a transformation that has been thought impossible ...
Space diamonds reveal supernova origins
Space diamonds may now be an astrophysicist's best friend.
Spitzer finds solid buckyballs in space
(PhysOrg.com) -- Astronomers using data from NASA's Spitzer Space Telescope have, for the first time, discovered buckyballs in a solid form in space. Prior to this discovery, the microscopic carbon spheres ...
