Step on the gas — New fuel cell design adds control, reduces complexity
When Princeton University engineers want to increase the power output of their new fuel cell, they just give it a little more gas - hydrogen gas, to be exact. view more (2007-01-17)
Electric Nudge toward Self-organization
In search of materials with nonlinear optical properties Window panes and eyeglass lenses that get darker as it gets brighter are especially great in the summer. Their secret lies in optical properties that change as the light intensity changes - nonlinear optical properties. Such materials are also of interest as optoelectronic components. One... view more... (2002-03-07)

Molds for Molecules
Molecular imprints in polymers as reaction vessels for pharmaceuticals research Materials with the tiniest of cavities, which can take up other molecules as "guests", play a meaningful role in science and technology. A particularly interesting process for the synthesis of materials with precisely fitted cavities is known as molecular imprinting.... view more... (2002-11-28)
Bug-Zapper: A dose of radiation may help knock out malaria
How are physicists helping an effort to eradicate malaria, the mosquito-borne disease that kills more than one million people every year" Researchers at the National Institute of Standards and Technology (NIST) used their expertise in radiation science to help a young company create weakened, harmless versions of the malaria-causing parasite. view more (2007-11-09)
Kingston University turns up heat on British olympians
World-class athletes will be coming to Kingston University to prepare for the heat and humidity of next year's Olympic Games in Athens after the British Olympic Association chosen the University as a centre for acclimatisation training. The decision means some of the country's top medal hopefuls will train in the University's environment chamber,... view more... (2003-06-13)
Nuclear medicine now safer than ever
Hospitals are now able to ensure that the correct dose is administered to the 670,000 patients that undergo nuclear medicine procedures every year due to a new device developed by scientists at the National Physical Laboratory (NPL). view more (2007-10-11)
'Microfluidic palette' may paint clearer picture of biological processes
The masterpieces that spring from the talents of Rembrandt, Van Gogh and other artists often begin with the creation of a gradient of colors on a palette. view more (2009-07-30)
Allergic-like reactions occur in premedicated patients
Allergic-like reactions can occur in patients (both children and adults) when given gadolinium containing contrast agents, even if they have been pre-medicated with corticosteroids and antihistamines, according to a recent study conducted by researchers at the University of Michigan Health Systems in Ann Arbor. view more (2008-02-11)
Hanover Trade Fair 2003: Zigzag for the maximum µ-concentration
The dielectrophoresis (DEP) chip as µ-concentrator for reliable analyses Developed jointly by the Institut für Mikrotechnik Mainz GmbH (IMM) and NorChip AS, the µ-concentrator is particular suitable for application in biomedical diagnostics. Using DEP, this chip enables the highly efficient separation and concentration of polarisable... view more... (2003-04-07)
In Birds, Expecting to Mate Leads to Higher Fertilization Rates
From an evolutionary perspective, the primary task of an organism is to pass along its genes to future generations. Such genetic transmission is usually assumed to be instinctive. However, a new study shows that species also learn to adapt to their surroundings in order to increase their "reproductive fitness"-- the likelihood that they... view more... (2007-10-05)
New biosensor could save lives by giving faster medical analysis.
Every day accident and emergency units have to treat patients who have taken some sort of drug overdose. To give treatment doctors need to know what the patient has taken. The circumstances can make often this difficult to ascertain quickly. Researchers are developing a new kind of biosensor, which can determine in minutes if a patient's blood... view more...

Gardens in space
A model of a system for growing plants to plan biological experiments in space has just left the company of ROVSING, in Ballerup near Copenhagen, on its way to ESA's European Space Research and Technology Centre (ESTEC) in the Netherlands. The full name of this experiment reference model is European Modular Cultivation System Experiment... view more... (2002-05-13)
Hope for treating relapse to methamphetamine abuse
A new study at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory suggests that vigabatrin (a.k.a. gamma vinyl-GABA, or GVG) blocks drug-seeking behavior in animals previously trained to associate methamphetamine with a particular environment. view more (2008-11-13)
Pitt, NETL researchers report molecular chain reaction thought to be impossible
People said it couldn't be done, but researchers from the University of Pittsburgh and the U.S. Department of Energy National Energy Technology Laboratory (NETL) in Pittsburgh demonstrated a molecular chain reaction on a metal surface, a nanoscale process with sizable potential in areas from nanotechnology to developing information storage... view more...

Einstein's tea leaves inspire new blood separation technique
Scientists at Monash University in Australia have developed a process for rapidly and efficiently separating blood plasma at the microscopic level without any moving parts, potentially allowing doctors to do blood tests without sending samples to a laboratory. view more (2007-01-18)
Deep magma matters in volcanic eruption cycle
Although the Soufriere Hills volcano on Montserrat exhibits cycles of eruption and quiet, an international team of researchers found that magma is continuously supplied from deep in the crust but that a valve acts below a shallower magma chamber, releasing lava to the surface periodically. view more (2008-10-10)
Two bacteria better than one in cellulose-fed fuel cell
No currently known bacteria that allow termites and cows to digest cellulose, can power a microbial fuel cell and those bacteria that can produce electrical current cannot eat cellulose. view more (2007-07-30)
Instant steam takes on MRSA
A method for making instant steam, without the need for electricity, promises to be useful for tackling antibiotic resistant 'superbugs' like MRSA and C. difficile, as well as removing chewing gum from pavements and powering environmentally friendly cars, reports Nina Morgan in Chemistry & Industry, the magazine of the SCI. view more (2007-07-30)
One in five asthmatics are highly sensitive to aspirin
One in five asthmatic patients are sensitive to aspirin, yet many are unaware that they are at risk of a potentially life threatening reaction known as aspirin induced asthma, warn researchers in this week's BMJ. Aspirin induced asthma is a severe reaction to aspirin and other commonly used painkillers, but controversy exists over its prevalence.... view more... (2004-02-18)
