Killer pulses help characterize special surfaces
Detecting deadly fumes in subways, toxic gases in chemical spills, and hidden explosives in baggage is becoming easier and more efficient with a measurement technique called surface-enhanced Raman scattering. To further improve the technique's sensitivity, scientists must design better scattering surfaces, and more effective ways of evaluating... view more... (2008-07-30)
Pulse pressure identified as important risk factor for atrial fibrillation
Increased pulse pressure (the difference between systolic and diastolic blood pressure) appears to be an important predictor of the risk for new onset atrial fibrillation. view more (2007-02-21)
Strengthening the tumor-fighting ability of T cells
When faced with cancer, the immune system dispatches cells, called T cells, to kill the tumor. But these killer cells often fail to completely eliminate the tumor because they're deactivated by a distinct population of T cells known as regulatory T cells. view more (2008-03-25)
Perforating aircraft wings with minute holes could make for more efficient flying.
One way to make aeroplanes fly more efficiently is to drill millions of tiny holes in the leading edges of the wings. Like the dimples on a golf ball this has the effect of reducing drag. However, producing these holes on a manufacturing scale is not yet commercially feasible. Researchers at Heriot-Watt University, funded by the Engineering and... view more... (2002-01-14)
In tiny supercooled clouds, physicists exchange light and matter
Physicists have for the first time stopped and extinguished a light pulse in one part of space and then revived it in a completely separate location. view more (2007-02-08)
HIV pays a price for invisibility
Mutations that help HIV hide from the immune system undermine the virus's ability to replicate, show an international team of researchers in the April 13 issue of the Journal of Experimental Medicine. view more (2009-04-13)
Catching the wave — Researchers measure very short laser pulses
Scientists have perfected a technique for very accurately measuring and controlling the electromagnetic waves within some of the shortest laser pulses ever made, says new research published today. view more (2006-12-04)
New Brain Test to Monitor Alzheimer's Disease
A new test that taps brain records so accurately it caught out a serial killer, could soon be used by pharmaceutical companies to speed up approval of drugs for Alzheimer's and other brain diseases, reports Marina Murphy in Chemistry & Industry Magazine. 'Brain Fingerprinting' is the patented technology that can measure objectively, for the... view more... (2004-03-15)
Light's Most Exotic Trick Yet: So Fast it Goes ... Backwards?
In the past few years, scientists have found ways to make light go both faster and slower than its usual speed limit, but now researchers at the University of Rochester have published a paper today in Science on how they've gone one step further: pushing light into reverse. view more (2006-05-12)
Animal magnetism provides a sense of direction
They may not be on most people's list of most attractive species, but bats definitely have animal magnetism. Researchers from the Universities of Leeds and Princeton have discovered that bats use a magnetic substance in their body called magnetite as an 'internal compass' to help them navigate. view more (2008-02-27)
Abertay scientist sets out to find undiscovered yeast
A University of Abertay Dundee scientist has braved scorching temperatures in harsh deserts to track down a new strain of "killer yeast" which could be used in agriculture and beer brewing. With a grant from NATO, Dr Graeme Walker recently flew out to Morocco to locate the Argan tree, a hardy plant which only grows in the arid climate of the... view more... (2002-05-03)
Immune Cell Communication, Cooperation Keys to Hunting Viruses, Jefferson Immunologists Show
Immunologists at the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia have used nanotechnology to create a novel 'biosensor' to solve in part a perplexing problem in immunology: how immune system cells called killer T-cells hunt down invading viruses. view more (2006-10-27)
Quantum memory and turbulence in ultra-cold atoms
Scientists at MIT have figured out a key step toward the design of quantum information networks. view more (2009-07-20)
Female katydids prefer mates 'cool' in winter and 'hot' in summer
Katydid (or didn't she?) respond to the mating call of her suitors. According to scientists at the University of Missouri, one species of katydid may owe its ecological success and expanded habitat range to the ability of male katydids to adjust their mating calls to attract females. view more (2008-03-12)
Ultrashort light pulse blazes new paths for science, industry
Researchers in Italy have created an ultrashort light pulse-a single isolated burst of extreme-ultraviolet light that lasts for only 130 attoseconds (billionths of a billionth of a second). view more (2007-05-02)
Warm water vibrates for longer
Dutch researcher Arjan Lock has investigated the behaviour of vibrating water molecules. Using ultra-short laser pulses, he found that hydrogen atoms in water molecules vibrate for longer at higher temperatures. This is abnormal because in the majority of substances a vibration lives shorter at higher temperatures. Lock studied the OH-stretch... view more... (2004-02-05)
Newborn screening test could increase early detection of heart disease and save lives
Routine screening of blood oxygen levels before discharge from hospital improves the detection of life threatening congenital heart disease in newborns and may save lives, according to a study published on bmj.com today. view more (2009-01-09)
Potential new pain killer drug developed by scientists at Leicester and Italy
A potential new pain-killing drug developed by medical scientists at the University of Leicester and Ferrara in Italy is to be discussed at a public lecture on 20th March. view more (2007-03-16)
What makes a killer?
Mind of a Murderer - The Mask of Sanity Tuesday 4th September, BBC 2 9.00pm A new three-part series exploring the inner workings of the minds of people who have killed starts on Tuesday 4 September on BBC 2. The first episode – The Mask of Sanity – looks at the mysterious and often misunderstood relationship between extreme violence... view more... (2001-09-03)
Oregon physicists don't flip spin but find possible electron switch
University of Oregon researchers trying to flip the spin of electrons with laser bursts lasting picoseconds (a trillionth of a second) instead found a way to manipulate and control the spin -- knowledge that may prove useful in a variety of new materials and technologies. view more (2008-05-28)
