Princeton researchers discover new type of laser
A Princeton-led team of researchers has discovered an entirely new mechanism for making common electronic materials emit laser beams. The finding could lead to lasers that operate more efficiently and at higher temperatures than existing devices, and find applications in environmental monitoring and medical diagnostics. view more (2008-12-23)
A resetting signal keeps circadian rhythm on track in Drosophila fruit flies
A Brandeis University study published this week in Nature shows for the first time that a molecular signal maintains coherence among brain clock cells that regulate daily activity of Drosophila melanogaster (fruit flies). view more (2005-11-10)
Scientists discover new method of observing interactions in nanoscale systems

Quantum analog of Ulam's conjecture can guide molecules, reactions
Like navigating spacecraft through the solar system by means of gravity and small propulsive bursts, researchers can guide atoms, molecules and chemical reactions by utilizing the forces that bind nuclei and electrons into molecules (analogous to gravity) and by using light for propulsion. view more (2007-08-08)
Quantum physics pioneer honoured in Bristol
According to a current magazine advertisement, quantum physics is getting easier. It’s doubtful whether most of the population would agree with this. However, today (12 December) in Bristol, one of the pioneers of quantum physics, Noble prize-winner Paul Dirac, is being commemorated in two separate ceremonies. The first is in the Bishopston... view more... (2000-12-08)
Manipulating light on a chip for quantum technologies
A team of physicists and engineers at Bristol University has demonstrated exquisite control of single particles of light - photons - on a silicon chip to make a major advance towards long-sought-after quantum technologies, including super-powerful quantum computers and ultra-precise measurements. view more (2009-06-09)
Physicists establish 'spooky' quantum communication
Physicists at the University of Michigan have coaxed two separate atoms to communicate with a sort of quantum intuition that Albert Einstein called "spooky." view more (2007-09-06)
NIST/Maryland Researchers Demonstrate 'Quantum Data Buffering' Scheme

Using tiny semiconductor crystals, biological probes and a laser, Johns Hopkins University engineers have developed a new method of finding specific sequences of DNA by making them light up beneath a microscope. view more (2005-12-06)
Research measures movement of nanomaterials in simple model food chain
New research shows that while engineered nanomaterials can be transferred up the lowest levels of the food chain from single celled organisms to higher multicelled ones, the amount transferred was relatively low and there was no evidence of the nanomaterials concentrating in the higher level organisms. view more (2008-06-02)
Record breaking quantum encryption
The latest steps towards an uncrackable code have been taken by scientists in both Switzerland and the US, who have found novel ways of generating and transmitting "quantum keys" respectively. Both techniques are reported today, 12 July 2002, in New Journal of Physics, published jointly by the Institute of Physics and the German Physical... view more... (2002-07-10)
