Scientists levitate diamond, lead and platinum
Scientists at The University of Nottingham have successfully levitated diamond and some of the heaviest elements, including lead and platinum. view more (2005-05-11)
Study finds possible connection between marijuana abuse and stroke or heart attacks
Long-term harmful effects of marijuana (MJ) include risk for heart attacks and strokes in addition to impaired learning and memory. The active chemical in MJ called delta-9-tetrahyrdocannabinol (THC) is believed to exert these effects by binding to cannabinoid (CB) receptors located on several cell types in various organs. view more (2008-05-13)
Bacteria Precipitate Gold
Roman A. Amosov and a team of Russian scientists from the Central Institute for Geological Exploration of Non-ferrous and Noble Metals, Institute of Paleontology, Russian Academy of Sciences, and from the Institute of Microbiology, Russian Academy of Sciences, led by, have managed to simulate in the laboratory the process of precipitation of gold... view more...

Exposures to metals and diesel emissions in air linked to respiratory symptoms in children
Exposure shortly after birth to ambient metals from residential heating oil combustion and particles from diesel emissions are associated with respiratory symptoms in young inner city children. view more (2009-11-24)
Women At Greater Risk Of Brain-Cell Damage From Long-Term Ecstasy Use
Authors of a Dutch study in this week's issue of THE LANCET conclude that long-term ecstasy use-especially among women-could have serious negative effects on specific cells in the brain. The study also suggests that the adverse effects of ecstasy use can sometimes be reversed among people who stop using the drug. Ecstasy is a popular recreational... view more... (2001-11-28)
Chasing thundersnow could lead to more accurate forecasts
The job of one University of Missouri researcher could chill to the bone, but his research could make weather predicting more accurate. view more (2009-01-14)
Bird fall-out measures radioactive fall-out
Jim Clapp (University of Ulster) will reveal how bird droppings can be used to measure radioactive fall-out in the environment. Solid urate spheres found in bird excretions can be screened for man-made pollutants such as radioactive caesium, providing a new non-invasive way to monitor the environment. Mr. Clapp will present his latest results... view more... (2004-03-30)
New generation of orthopedic, dental and cardiovascular prostheses
The futuristic technology of the Six Million Dollar Man -specifically a part metal and part flesh human being - won't be exclusive to Hollywood anymore. view more (2009-01-28)
Heavy, chronic drinking can cause significant hippocampal tissue loss
The hippocampus is a brain structure vital to learning and memory. It also appears vulnerable to damage from chronic, heavy alcohol consumption. view more (2006-10-25)
Gene may inhibit smokers from quitting
Smokers with a particular genetic make-up (genotype) may find it harder to give up their habit, suggest Japanese researchers in Thorax. The presence of a CYP2A6del allele, a specific form of the gene involved in processing nicotine in the body, may inhibit smokers from quitting, but it also seems to protect against the development of pulmonary... view more...

New X-ray microbeam answers 20-year-old metals question
What happens to metals when you bend them? The question isn't as easy as you may think. A research team from the National Institute of Standards and Technology (NIST), Oak Ridge National Laboratory (ORNL), and the University of Southern California, using a unique X-ray probe, has gathered the first direct evidence showing that, on average, a... view more...

Changing the rings: a key finding for magnetics design
Researchers at the National Institute of Standards and Technology's Center for Nanoscale Science and Technology (CNST) have done the first theoretical determination of the dominant damping mechanism that settles down excited magnetic states-"ringing" in physics parlance-in some key metals. view more (2007-08-06)
Metals Shape Up with a Little Help from Friends
For 5,000 years the only way to shape metal has been by the "heat and beat" technique. Even with modern nanotechnology, metalworking involves carving metals with electron beams or etching them with acid. view more (2008-07-01)
Predicting Volcanic Eruptions
The weather forecast could help predict volcanic eruptions, according to new research from the University of East Anglia (UEA). Scientists from UEA`s School of Environmental Sciences found that intense rainfall can trigger volcanic dome collapse - a particular type of eruption that occurs when a build-up of molten rock inside the side of the... view more...

The Largest Congress Worldwide on Ion Therapy in Heidelberg
The largest congress worldwide on the topic of particle or ion therapy - radiation with heavy ions and protons - has taken place in the fall of 2009 in Heidelberg. view more (2009-10-27)
Alcohol and high-risk sexual behaviors in Botswana
Heavy alcohol consumption is strongly and consistently associated with sexual risk behaviors in both men and women in Botswana, according to one of the few research studies on the topic in sub-Saharan Africa. view more (2006-10-10)
Alcoholism-associated molecular adaptations in brain neurocognitive circuits
After many years of heavy drinking, alcohol produces pathological alterations in the brain. In many alcoholics these changes culminate in massive social deterioration and disorders of memory and learning. view more (2008-07-09)
Ultrasounds show mothers' drinking shrinks fetal brain
Routine ultrasounds show that heavy drinkers who continue to imbibe after learning they are pregnant may carry fetuses with reduced skull and brain growth compared to those of abstainers or quitters, says a new study. view more (2006-04-28)
Heavy smokers who cut their smoking in half may reduce their risk of lung cancer
Heavy smokers (more than 15 cigarettes per day) can reduce their risk of lung cancer if they decrease smoking by 50 percent, according to a study in the September 28 issue of JAMA. view more (2005-09-28)
Medication shows promise as a treatment for alcohol dependence
Alcohol-dependent patients who received the medication topiramate had fewer heavy drinking days, fewer drinks per day and more days of continuous abstinence than those who received placebo. view more (2007-10-10)
