New malaria enzyme laid bare with help of computer calculations
Using only computers, a research team at Uppsala University in Sweden has managed to reveal both the structure and the function of a newly discovered enzyme from the most dangerous malaria parasite, Plasmodium falciparum. All that was needed was the amino acid sequence of the enzyme. The findings may represent a breakthrough for future... view more... (2004-12-07)

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)

Caffeine limits blood flow to heart muscle during exercise
In healthy volunteers, the equivalent of two cups of coffee reduced the body's ability to boost blood flow to the heart muscle in response to exercise, and the effect was stronger when the participants were in a chamber simulating high altitude.   view more (2006-01-16)

World's oldest ritual discovered
A startling archaeological discovery this summer changes our understanding of human history. While, up until now, scholars have largely held that man's first rituals were carried out over 40, 000 years ago in Europe, it now appears that they were wrong about both the time and place.   view more (2006-11-30)

Small molecule interactions were central to the origin of life
In an important new paper forthcoming in the June issue of The Quarterly Review of Biology, Robert Shapiro (New York University) argues against the widely held theory that the origin of life began with the spontaneous appearance of a large, replicating molecule such as RNA.   view more (2006-05-17)

Nicotine exposure during development leads to hearing problems
Scientists know that children of women who smoke during pregnancy can develop hearing-related cognitive deficits. For the first time, researchers believe they have evidence that not only implicates nicotine as the culprit, but also shows what the substance does to the brain to cause these deficits.   view more (2006-07-19)

Multitasking is hardest in the early morning
Multitasking seems to come easier for some and is virtually impossible for others, however new research shows that it is difficult for all in the late night and early morning.   view more (2007-05-07)

‘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)

Towards the mechanism of cell respiration
Researchers at the Institute of Biotechnology of the University of Helsinki have for the first time identified an internal electron transfer reaction that initiates the proton pump mechanism of the respiratory enzyme.   view more (2006-04-06)

Slowing the racing heart
Researchers at the University of Illinois at Chicago explain in the May 11 issue of Circulation Research how an enzyme acts on the heart's pacemaker to slow the rapid beating of the heart's "fight-or-flight" reaction to adrenaline.   view more (2007-05-14)

Allergy season: Cigarettes to the rescue?
Everyone knows that smoking can kill you, but did you know that it may help with your allergies? A new study shows that cigarette smoke can prevent allergies by decreasing the reaction of immune cells to allergens.   view more (2009-05-15)

Sulfur signature changes thoughts on atmospheric oxygen
Ancient sediments that once resided on a lake bed and the ocean floor show sulfur isotope ratios unlike those found in other samples from the same time, calling into question accepted ideas about when the Earth's atmosphere began to contain oxygen.   view more (2006-08-24)

Structure of enzyme offers treatment clues for diabetes, Alzheimer's
Researchers from the University of Chicago and Argonne National Laboratory have deciphered the three-dimensional structure of insulin-degrading enzyme, a promising target for new drugs because it breaks down not only insulin but also the amyloid-beta protein, which has been linked to the cognitive decline of Alzheimer's disease.   view more (2006-10-12)

Plants can be used to study how and why people respond differently to drugs
While prescription medications work successfully to cure an ailment in some people, in others the same dose of the same drug can cause an adverse reaction or no response at all.   view more (2007-09-27)

When gold becomes a catalyst
Gold has always been perceived as a precious material: you win a gold medal when you prove to be the best in a competition; you only get a Gold credit card when you are a preferential customer, and the jewelry made of this material is amongst the most valuable.   view more (2006-06-23)
