It will be possible to predict earthquakes from space
The scientists of the Department of Physics, Moscow State University, have proposed to predict earthquakes by measuring polarization of the solar light that is reflected from the surface of the Earth. The small and cheap equipment, which the scientists have designed, can be placed on meteorological satellites. Polarization of solar light at... view more... (2001-01-17)

Polarized light guides cholera-carrying midges that contaminate water supplies
Cholera is a major killer and since the first pandemic in the early 19th century it has claimed millions of lives. According to Amit Lerner from The Hebrew University of Jerusalem, Israel, the lethal infection is harboured by an equally infamous insect: chironomids (midges). view more (2008-10-31)
NRL scientists demonstrate efficient electrical spin injection into silicon
Scientists at the Naval Research Laboratory (NRL) have efficiently injected a current of spin-polarized electrons from a ferromagnetic metal contact into silicon, producing a large electron spin polarization in the silicon. view more (2007-07-17)
Precise picture of early Universe supports 'dark matter' theory
A detailed picture of the seeds of structures in the universe has been unveiled by an international team co-led by a Cardiff University scientist. view more (2009-11-03)
2 for 1: NIST design enables more cost-effective quantum key distribution
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a simpler and potentially lower-cost method for distributing strings of digits, or "keys," for use in quantum cryptography, the most secure method of transmitting data. view more (2008-05-30)
Polarizers may enhance remote chemical detection
Chemists can analyze the composition of a suspected bomb -- without actually touching and possibly detonating it -- using a technique called laser-induced breakdown spectroscopy, or LIBS. view more (2009-03-12)
U of T physicists are first to 'squeeze' light to quantum limit
A team of University of Toronto physicists have demonstrated a new technique to squeeze light to the fundamental quantum limit, a finding that has potential applications for high-precision measurement, next-generation atomic clocks, novel quantum computing and our most fundamental understanding of the universe. view more (2009-01-07)

Goddard-Led GEMS Mission to Explore the Polarized Universe
An exciting new astrophysics mission led by NASA's Goddard Space Flight Center in Greenbelt, Md., will provide a revolutionary window into the universe. Named the Gravity and Extreme Magnetism Small Explorer (GEMS), the satellite will be the first to systematically measure the polarization of cosmic X-ray sources. view more (2009-08-05)
To regenerate muscle, cellular garbage men must become builders
For scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy, what seemed like a disappointing result turned out to be an important discovery. view more (2009-09-23)
New system for detection of single atoms
Scientists have devised a new technique for real-time detection of freely moving individual neutral atoms that is more than 99.7% accurate and sensitive enough to discern the arrival of a single atom in less than one-millionth of a second, about 20 times faster than the best previous methods. view more (2009-05-18)
JQI researchers create entangled photons from quantum dots
To exploit the quantum world to the fullest, a key commodity is entanglement-the spooky, distance-defying link that can form between objects such as atoms even when they are completely shielded from one another. view more (2009-11-18)
Structuring polymers by laser
Microstructured polymer components are often used to direct light in optical devices. As an alternative to mechanical processes, laser light can also be used to produce the microscopic relief structures, and even to remove them without contact. With a flash of blue-green light, the show begins. Like a line of silent ballet dancers, long-chain... view more... (2004-05-14)
