Hebrew University, German And British Researchers Develop Means To Help Post-Traumatic Stress Sufferers
Try as we may to suppress memories of highly stressful experiences, they nevertheless come back to bother us - even causing attacks of intense fear or other undesirable behavioral impairments. Now a group of German, Israeli and British scientists and students have found that a gene-based approach offers promise for development of a treatment that... view more... (2003-12-11)
Doctors should play no part in executions
The number of executions in the United States has soared over the past two decades as the acceptability of lethal injection has increased. In this week's BMJ Jonathan Groner describes parallels between America's use of lethal injection and Nazi Germany's "euthanasia" programme, and argues that doctors should not participate in executions... view more...

Ultraviolet radiation induced flux of nitrogen oxides from pine needles
In the latest edition of Nature (March 13th, 2003) a group of scientist led by professor Pertti Hari from the University of Helsinki presents a novel observation: ultraviolet radiation induced a flux of nitrogen oxides (NOx) from pine needles to the atmosphere. This result is interesting because nitrogen oxides participate in several essential... view more... (2003-03-14)
Research Matters at the Arizona Health Sciences Center (AHSC): UA Researchers Seek Safer Cystic Fibrosis Test
Researchers from The University of Arizona Colleges of Pharmacy and Medicine are teaming up to try to invent a novel non-invasive lung test for cystic fibrosis sufferers. view more (2009-09-10)
New clues about a hydrogen fuel catalyst
To use hydrogen as a clean energy source, some engineers want to pack hydrogen into a larger molecule, rather than compressing the gas into a tank. view more (2009-08-05)
Study shows risk of acute pancreatitis low with statins
New research reveals that while cholesterol-lowering drugs do increase the risk of painful inflammation of the pancreas, the side effect is relatively rare, according to Sonal Singh, M.D., from Wake Forest University School of Medicine, and colleagues. view more (2007-01-02)
Piece from childhood virus may save soldiers' lives
A harmless shard from the shell of a common childhood virus may halt a biological process that kills a significant percentage of battlefield casualties, heart attack victims and oxygen-deprived newborns. view more (2009-09-08)
New aluminum-water rocket propellant promising for future space missions
Researchers are developing a new type of rocket propellant made of a frozen mixture of water and "nanoscale aluminum" powder that is more environmentally friendly than conventional propellants and could be manufactured on the moon, Mars and other water-bearing bodies. view more (2009-10-08)
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)
Concrete less sensitive for cracks than previously thought
Reinforced high-strength concrete can crack due to stresses that develop during the hardening process. However, this has been found to be surprisingly less quick than previously thought. Due to Dutch research, extra steps during the hardening process can be omitted. This will result in cheaper concrete. view more (2003-03-21)
Evolutionary phenomenon in mice may explain human infertility
Scientists at the University of Liverpool have found that field mice have evolved a unique way of ensuring faster fertilisation, a phenomenon which could explain some cases of infertility in humans. view more (2008-01-23)
Space X-ray telescope arrives for tests at RAL
An X-ray telescope weighing half a tonne, due for launch on a Russian spacecraft in 1998, arrived at CLRC's Rutherford Appleton Laboratory today for thermal tests. With conditions in space so different from those on Earth (space is an icy-cold vacuum), it is vital to test any instrument before launch to make sure that it can work in a vacuum at... view more...

University of Toronto chemists uncover green catalysts
A University of Toronto research team from the Department of Chemistry has discovered useful "green" catalysts made from iron that might replace the much more expensive and toxic platinum metals typically used in industrial chemical processes to produce drugs, fragrances and flavours. view more (2009-04-14)
Even natural perfumes may cause allergies
Hypersensitivity to perfumes is the most common contact allergy in adults. Research at the University of Gothenburg has demonstrated that even natural aromatic oils, which many deem harmless compared to synthetic perfumes, may cause allergic reactions. view more (2009-02-04)
Study charts origins of fear
A team of researchers led by the University of Toronto has charted how and where a painful event becomes permanently etched in the brain - a discovery that has implications for pain-related emotional disorders such as anxiety and post-traumatic stress. view more (2005-09-16)
MPH improves vigilance performance of ADHD children with poor sleep
In the first known study of its kind, an article published in the August 1st issue of the journal SLEEP finds that children with attention deficit hyperactivity disorder (ADHD), and whose sleep efficiency is poor, experience significant improvement on some measures of the Continuous Performance Test (CPT) if they are treated with methylphenidate... view more...

Gold, copper nanoparticles take center stage in the search for hydrogen production catalysts
X-ray studies at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory are pointing the way to less costly and more efficient catalysts for improving the performance of fuel cells. view more (2007-03-29)
‘Perfume’ lures flies into trap
As part of a project funded by the NWO’s Technology Foundation (STW), a Groningen research team has investigated how flies react to the odours of such things as old pork, bread and chicken manure. The findings will be used to develop more effective flytraps, for example for use in stables. Flies are attracted to decaying and fermenting... view more... (2001-05-30)
PIONEERING LOW-COST MEDICAL SCANNER DEVELOPED IN THE UK
A new type of medical imaging camera which is much less expensive than its conventional counterpart has been developed by researchers funded by the Engineering and Physical Sciences Research Council. The imaging method - positron emission tomography - is becoming increasingly important in the diagnosis of many diseases, especially cancer.Clinical... view more... (2000-07-10)
Common abdominal pain may be due to a potentially treatable newly recognized inflammatory reaction
As many as one in four people in westernized countries experience pain or discomfort in their upper abdomen, and physicians have almost nothing to offer except anti-acid medicines, which usually don't work. view more (2007-09-20)
