The Universe, seen under the Gran Sasso mountain, seems to be older than expected
Some nuclear fusion reactions inside stars occur more slowly than we thought and, as a consequence, stars themselves, as well as galaxies and the entire universe are a bit older than expected. This is what comes out from the last results of Luna experiment (Laboratory for Underground Nuclear astrophysics), settled by National Laboratories of Gran... view more... (2004-05-13)
Fuzzy logic water quality
A fuzzy logic approach to analyzing water quality could help reduce the number of people in the developing world forced to drink polluted and diseased water for survival. view more (2008-04-18)
International team of scientists discover clue to delay of life on Earth
Scientists from around the world have reconstructed changes in Earth's ancient ocean chemistry during a broad sweep of geological time, from about 2.5 to 0.5 billion years ago. view more (2008-03-27)
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)
Why are so many people dying on Everest?
It used to be thought that it would be physiologically impossible to climb Mount Everest with or without oxygen. In 1953 Hillary and Tenzing proved that it was possible to reach the summit with oxygen and in 1978 Messner and Habeler demonstrated it was possible without oxygen. view more (2006-08-25)
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)
Management of asthma during pregnancy can optimize health of mother and baby
Pregnant women with asthma, the most common condition affecting the lungs during pregnancy, should actively manage their asthma in order to optimize the health of mother and the baby, according to new management recommendations published in the current issue of the New England Journal of Medicine. view more (2009-04-30)
Higher nitric oxide levels increase survival in ALI/ARDS trial
In a large-scale, multi-center trial of patients with acute lung injury (ALI) or acute respiratory distress syndrome (ARDS), researchers showed that higher levels of nitric oxide (NO) in patient urine were strongly associated with improved survival, more ventilator-free days, and decreased rates of organ failure. view more (2007-02-01)
Sleep Apnea May Be Risk Factor for Sudden Cardiac Death, Mayo Clinic Research Concludes
After studying the sleep characteristics of nearly 11,000 adults in an overnight sleep laboratory, Mayo Clinic researchers suggest that obstructive sleep apnea (OSA) - and, in particular, the low nighttime oxygen saturation of the blood it causes - may be a risk factor for sudden cardiac death (SCD). view more (2008-11-10)
Catalysis discovery takes aim at NOx emissions
A discovery in molecular chemistry may help remove a barrier to widespread use of diesel and other fuel-efficient "lean burn" vehicle engines. Researchers at the Department of Energy's Pacific Northwest National Laboratory have recorded the first observations of how certain catalyst materials used in emission control devices are... view more...

Destroying amyloid proteins with lasers
Researchers have found that a technique used to visualize amyloid fibers in the laboratory might have the potential to destroy them in the clinic. view more (2009-01-08)
Prenatal nicotine exposure reduces breathing response of newborns
Exposure to nicotine the equivalent of smoking two packs of cigarets a day produced complicated, abnormal breathing development during the first 18 days of newborn rats, University of Arizona researchers report. view more (2006-04-06)
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)
Jefferson researchers find nanoparticle shows promise in reducing radiation side effects
Using transparent zebrafish embryos, researchers at Jefferson Medical College have shown that a microscopic nanoparticle can help fend off damage to normal tissue from radiation. view more (2005-11-15)
ABCB6 is key to production of heme in hemoglobin
Investigators at St. Jude Children's Research Hospital have discovered that a protein called ABCB6 plays a central role in production of a molecule that is key to the ability of red blood cells to carry oxygen, of liver cells to break down toxins, and of cells to extract energy from nutrients. view more (2006-09-29)
Stellar forensics with striking new image from Chandra
A spectacular new image shows how complex a star's afterlife can be. By studying the details of this image made from a long observation by NASA's Chandra X-ray Observatory, astronomers can better understand how some stars die and disperse elements like oxygen into the next generation of stars and planets. view more (2007-10-24)
Marine 'dead zone' off Oregon is spreading
A hypoxic "dead zone" has formed off the Oregon Coast for the fifth time in five years, according to researchers at Oregon State University. view more (2006-07-28)
Key process for space outpost proved on 'vomit comet' ride
Flying high over the Gulf of Mexico, researchers from NASA and Case Western Reserve University found a key to unlocking oxygen from the surface of the moon. view more (2009-09-25)
Low oxygen in coastal waters impairs fish reproduction
Low oxygen levels in coastal waters interfere with fish reproduction by disrupting the fishes' hormones, a marine scientist from The University of Texas at Austin Marine Science Institute has found. view more (2007-08-29)
Deadly hypoxic event finally concludes
The longest, largest and most devastating hypoxic event ever observed in marine waters off the Oregon Coast has finally ended. view more (2006-10-31)
