Stars stop forming when big galaxies collide
Astronomers studying new images of a nearby galaxy cluster have found evidence that high-speed collisions between large elliptical galaxies may prevent new stars from forming, according to a paper to be published in a November 2008 issue of The Astrophysical Journal Letters. view more (2008-10-08)
Scientists create metal that pumps liquid uphill
In nature, trees pull vast amounts of water from their roots up to their leaves hundreds of feet above the ground through capillary action, but now scientists at the University of Rochester have created a simple slab of metal that lifts liquid using the same principle-but does so at a speed that would make nature envious. view more (2009-06-03)
Scientists discover gene that controls speed of tuberculosis development
Scientists at the MUHC have discovered a gene that controls the speed at which patients develop tuberculosis-the first time such a gene has been discovered for this disease. view more (2005-08-17)
Light turns liquid
LIGHT can be turned into a glowing stream of liquid that splits into droplets and splatters off surfaces just like water. The researchers who`ve worked out how to do this say "liquid light" would be the ideal lifeblood for optical computing, where chips send light around optical "circuits" to process data. Liquid light sounds like a... view more... (2002-07-03)
New technology may help Olympic sailing
A team of researchers at the Ocean University of China has developed and tested a mobile lidar (light detection and ranging) station that can accurately measure wind speed and direction over large areas in real time -- an application useful for aviation safety, weather forecasting and sports. view more (2008-07-01)
The Speed Of Learning The New Language Protects Against Psychological Symptoms In Refugees
The aim of this research is to study the effects of symptoms of posttraumatic stress disorder (PTSD), depression and dissociation as well as cumulative symptom load on language learning during the introduction phase in resettled refugees. Participants were resettled refugees of Iraqi origin. They were assessed by means of a structured interview... view more... (2004-08-31)
Speedy diagnosis at the doctor's office
Biochemical reactions can be monitored with the help of biosensors, allowing rapid analysis of blood counts or identification of toxins in water or foodstuffs. The biosensors employ selective biochemical reactions, based on the so-called lock-and-key principle to detect specific. In the case of an immune response, for example, an antibody attaches... view more... (1999-07-01)
Molecular machines drive plasmonic nanoswitches
Plasmonics -- a possible replacement for current computing approaches -- may pave the way for the next generation of computers that operate faster and store more information than electronically-based systems and are smaller than optically-based systems, according to a Penn State engineer who has developed a plasmonic switch. view more (2009-02-12)
Broadband for all from High Altitude Platforms - York leads international project
An international project aims to make Broadband available to remote rural areas and even moving trains, thanks to 'High Altitude Platforms' (HAPs). HAPs are airships or solar-powered aircraft, which are permanently located in the skies at an altitude of 20 km, above aeroplanes but below satellites. This solution will be cheaper and more efficient... view more... (2004-01-19)
Fermi telescope caps its first year with a glimpse of space-time
During its first year of operations, NASA's Fermi Gamma Ray Space Telescope mapped the extreme sky with unprecedented resolution and sensitivity. view more (2009-10-29)
Engineering the road to safer streetlighting
An innovative engineering project could lead to fewer night-time accidents on badly lit roads. It is developing a revolutionary way of assessing whether roads are equipped with appropriate levels of streetlighting. The new assessment system is quicker, cheaper and more comprehensive than methods previously used. It can also help local... view more... (2002-12-09)
Inderscience Publishers
A way to make wind power smoother and more efficient that exploits the inertia of a wind turbine rotor could help solve the problem of wind speed variation, according to research published in the International Journal of Power Electronics. view more (2009-01-08)
Measuring the smallest particles
When someone says: "Everything flows - nothing stays the same", he seldomly refers to toothpaste, ointment or paint. However, manufacturers are immensely interested in the way in which such products "flow" in daily use. For example, wall paint should be thin in consistency, easy to work with and still adhere to walls after application. The amount... view more... (2001-06-25)
New on-off 'switch' triggers and reverses paralysis in animals with a beam of light
In an advance with overtones of Star Trek phasers and other sci-fi ray guns, scientists in Canada are reporting development of an internal on-off "switch" that paralyzes animals when exposed to a beam of ultraviolet light. view more (2009-11-19)
Have scanner, will travel
No train will travel where safe passage is not guaranteed. Shifted rails or a tree growing too close to the track is an accident waiting to happen. To clear the way for safer travel, a rapid laser scanner measures the clearance profile surrounding the train. We all need our own space - even a locomotive with cars. For this reason, rail operators... view more... (2004-02-03)
Tiny lasers get a notch up
Tiny disk-shaped lasers as small as a speck of dust could one day beam information through optical computers. Unfortunately, a perfect disk will spray light out, not as a beam, but in all directions. view more (2009-01-23)
A sub-femtosecond stop watch for 'photon finish' races
Using a system that can compare the travel times of two photons with sub-femtosecond precision, scientists at the Joint Quantum Institute (a partnership of the National Institute of Standards and Technology (NIST) and the University of Maryland) and Georgetown University have found a remarkably large difference in the time it takes photons to pass... view more...

Cancer diagnosis - the Star Trek way
A small portable optical tool that can simply be pointed at the body to detect cancerous cells or reveal how body tissue is being affected by laser or cryogenic therapy could one day be the result of research being carried out by laser physicists at Imperial College. view more (2000-03-21)
NIST/Maryland Researchers Demonstrate 'Quantum Data Buffering' Scheme
Pushing the envelope of Albert Einstein's "spooky action at a distance," known as entanglement, researchers at the Joint Quantum Institute (JQI) of the Commerce Department's National Institute of Standards and Technology (NIST) and the University of Maryland have demonstrated a "quantum buffer," a technique that could be used... view more...

New light detector
A novel prototype light meter has been developed by researchers in New York. Published today in the Institute of Physics journal, Measurement Science and Technology, this new retinal flux density meter will provide an affordable tool for measuring light at all levels and might ultimately lead to new standards to improve both energy efficiency and... view more...
