Dual internal clocks keep plant defenses on schedule
Time management isn't just important for busy people—it's critical for plants, too. A Duke University study shows how two biological clocks work together to help plants deal with intermittent demands such as fungal infections, ...
Nano-antioxidants prove their potential
Injectable nanoparticles that could protect an injured person from further damage due to oxidative stress have proven to be astoundingly effective in tests to study their mechanism.
Team uncovers fundamental property of astatine, rarest atom on Earth
An international team of scientists, including a University of York researcher, has carried out ground-breaking experiments to investigate the atomic structure of astatine (Z=85), the rarest naturally occurring ...
Hydrogen fuel cell for phone charging set for 2013
Power behind primordial soup discovered
(Phys.org) —Researchers at the University of Leeds may have solved a key puzzle about how objects from space could have kindled life on Earth.
New method of incorporating fluoride into drugs
The quantum secret to alcohol reactions in space
Chemists have discovered that an 'impossible' reaction at cold temperatures actually occurs with vigour, which could change our understanding of how alcohols are formed and destroyed in space.
Thinnest graphene sheets react strongly with hydrogen atoms; thicker sheets are relatively unaffected
(Phys.org)—Single sheets of graphene, a curious material only 1 atom thick, are 100 times more chemically reactive than double or triple sheets, Stanford scientists say in a new paper published online Jan. ...
New interferometer could simplify materials research
Exposure to air transforms gold alloys into catalytic nanostructures
(Phys.org) —Gold bars may signify great wealth, but the precious metal packs a much more practical punch when shrunk down to just billionths of a meter. Unfortunately, unlocking gold's potential often requires ...
German scientists solve nonclassical 2-norbornyl carbocation structure
Physicists achieve elusive 'evaporative cooling' of molecules
Achieving a goal considered nearly impossible, JILA physicists have chilled a gas of molecules to very low temperatures by adapting the familiar process by which a hot cup of coffee cools.
'Molecular levers' may make materials better
(Phys.org)—In a forced game of molecular tug-of war, some strings of atoms can act like a lever, accelerating reactions 1000 times faster than other molecules. The discovery suggests that scientists could ...
'Glowing' new nanotechnology guides cancer surgery, also kills remaining malignant cells
Researchers at Oregon State University have developed a new way to selectively insert compounds into cancer cells - a system that will help surgeons identify malignant tissues and then, in combination with ...
