Discovery of non-blinking semiconductor nanocrystals advances their applications
Substantial advances for applications of nanocrystals in the fields requiring a continuous output of photons and high quantum efficiency may soon be realised due to discovery of non-blinking semiconductor nanocrystals....
String Theory: Equivalence Principle In Space Test
Since Galileo Galilei and Newton, the assumption is valid that inert and heavy mass are equivalent. This is, however, questioned by new physical theories such as the String theory. Now,...
A 'cloaking device' -- it's all done with mirrors
(PhysOrg.com) -- Somewhat the way Harry Potter can cover himself with a cloak and become invisible, Cornell researchers have developed a device that can make it seem that a bump...
Milestone in live microscopy focus of $2 million NIH grant
A proposal by a team of UC Davis scientists to develop the world's first electron microscope capable of filming live biological processes has been awarded a $2 million grant from...
Planck 'Time Machine' to Study Big Bang
Planck will map the relic light of the Big Bang to learn more about the universe in its infancy.
Austrian Physicists Protest CERN Pull-out
Austrian physicists are protesting their nation's decision to withdraw from the CERN particle physics lab.
High-pressure Compound Could Be Key To Hydrogen-powered Vehicles
A recently discovered hydrogen-rich compound may help overcome one of the biggest hurdles to using hydrogen for fuel -- namely, how do you stuff enough hydrogen into a volume small...
Spiral swimmers may prove micro workhorses (w/Video)
(PhysOrg.com) -- Harvard researchers have created a new type of microscopic swimmer: a magnetized spiral that corkscrews through liquids and is able to deliver chemicals and push loads larger than...
New 'smart' polymer reduces radioactive waste at nuclear power plants
Scientists in Germany and India are reporting development of a new polymer that reduces the amount of radioactive waste produced during routine operation of nuclear reactors. Their study, which details...
Ground Control to Major Tom: London ISA Catches Speeders
An Intelligent Speed Adaption (ISA) system is being tested by the London for Transport (TfL). The eye-in-the-sky ISA system relies on a computer installed in the vehicle with pre-loaded...

Particles, Molecules Prefer Not To Mix
In the world of small things, shape, order and orientation are surprisingly important, according to findings from a new study. Chemists used computer simulations to study a very simple model...
Chemists Develop New Preparation Process For Metal-organic Frameworks
Many molecular materials, be they hydrogen for fuel cells or drugs, can be stored in metal-organic frameworks (MOFs). This would even be possible for metal nano particles for catalysis, were...
Cheap sensor finds pollutants
A team of researchers have developed a low-cost way to test for agricultural water contaminants, such as pesticide residues.
Device keeps divers safe
Divers will soon be safer underwater, thanks to a small safety device that helps them easily locate their boat or dive buddy.
Skin Color Clue To Nicotine Dependence
Higher concentrations of melanin -- the color pigment in skin and hair -- may be placing darker pigmented smokers at increased susceptibility to nicotine dependence and tobacco-related carcinogens than lighter...
Carbon Nanotubes: Innovative Technology Or Risk To Health Or Environment?
On the one hand, carbon nanotubes raise hopes for innovative applications in fields ranging from technology to medicine, promising considerable economic benefits. On the other hand, there is still need...
