What Makes The Scorpion`S Sting Deadly Poisonous?
Even the scorpion`s exterior warns that this is a dangerous animal. And it proves to be true, as nothing good comes out when small animals and even human beings meet with this arthropod species: its sting causes a sharp pain, some tropical scorpion`s sting is often fatal for the victim. The scientists from the Moscow Institute for Organoelement... view more... (2002-03-15)

What Shall We Do With Nuclear Waste?
There are two ways of dealing with the problem of nuclear waste. The first one is the easiest but not the most sensible: you can simply bury nuclear waste products and try to forget about them. However, this way does not seem to be the most rational. It seems much more attractive to try to derive some benefit from the situation. In this case it is... view more... (2002-03-12)
Emulating Western lifestyles: Consumption and carbon footprints in less industrialized countries
In recent decades, a new global middle class has exploded, with a total population exceeding one billion people. A new study in the Journal of Consumer Research explores the consumption attitudes of some of these members of the "new class." view more (2009-11-18)
Fish Blood Preserves Sperm
In the Arctic and Antarctic seas the water gets cold to minus 1.9 C in winter, but somehow some fish live there. These cold-blooded creatures survive in the icy water because the blood in their veins contains antifreeze proteins and glycoproteins. High levels of the antifreeze proteins are found in the blood serum, they are present in cell... view more... (2002-06-04)
Fill up with biodiesel, please
One day, petroleum and fuels derived from it will be exhausted. Moreover, every time we take to the road in our vehicle, the mark we leave on the natural environment is huge. Nowadays, new alternatives to fossil fuels are being developed. One of these is biodiesel, a fuel produced from vegetable oil. For a month now this biodiesel can be found in... view more...

Cardiac resynchromization: Race, age, geography matter, study shows
Race, age, and geography appear to play important roles in who receives cardiac resynchronization therapy (CRT), a proven treatment for some patients with heart failure, say researchers at Duke Clinical Research Institute (DCRI). view more (2008-08-12)
`Glowing` technique could detect river pollution
New technology used to analyse dissolved organic matter in river water could also help scientists detect and monitor pollution, according to a new research published in the journal Hydrological Processes (1). Dissolved organic matter is found in all river water, and can come from both a natural source such as the soil, as well as human sources... view more... (2002-10-07)
Lisa And The Search For Elusive Gravity Waves
For almost 100 years, scientists have been searching for direct evidence of the existence of gravity waves - faint ripples in the fabric of spacetime predicted in Albert Einstein's theory of General Relativity. view more (2005-03-31)

Measurements from the edge: magnetic properties of thin films
Materials researchers at the National Institute of Standards and Technology (NIST), together with colleagues from IBM and the Massachusetts Institute of Technology, have pushed the measurement of thin films to the edge-literally-to produce the first data on how the edges of metallic thin films contribute to their magnetic properties. view more (2007-10-01)
WFU study finds that moths mimic sounds to survive
In a night sky filled with hungry bats, good-tasting moths increase their chances of survival by mimicking the sounds of their bad-tasting cousins, according to a new Wake Forest University study. view more (2007-05-31)
Ability to cope with stress can increase 'good' cholesterol in older white men, study finds
Older white men who are better able to cope with stress experience higher levels of so-called "good cholesterol" than men who are more hostile or socially isolated, according to a study released at the 115th Annual Convention of the American Psychological Association. view more (2007-08-20)
Finding the needle in a chemical haystack
Imagine you're standing in the middle of a crowded square, and you've been asked to find one particular person. But all you know is that he or she speaks a specific dialect. A similar situation is faced by chemists hunting for pharmacologically useful ingredients in natural plant extracts. Out of the several hundred substances in the complex... view more... (2003-07-25)
Airbags will become even safer
Russian scientists are successfully developing smokeless gunpowder for automobile airbags, under ISTC Project #1882. This powder combusts almost instantaneously at the most important moment, but the airbag will fill with a gas that is harmless to the passenger, not like known compositions today. view more (2005-03-03)
Statins effective in long term, Nordic study suggests (p 771)

Automated tissue engineering on demand
Skin from a factory - this has long been the dream of pharmacologists, chemists and doctors. Research has an urgent need for large quantities of 'skin models', which can be used to determine if products such as creams and soaps, cleaning agents, medicines and adhesive bandages are compatible with skin, or if they instead will lead to irritation or... view more...
