Amphibians as environmental omen disputed
Amphibians, for years considered a leading indicator of environmental degradation, are not uniquely susceptible to pollution, according to a meta-analysis to be published in Ecology Letters.   view more (2009-11-12)

British oceanographers find 'smoking' submarine volcano in the Indian Ocean
At over three thousand metres down in the north-west Indian Ocean, the Carlsberg Ridge is "probably the best ridge in the world". So say excited scientists from Southampton Oceanography Centre who have just found the first evidence of hydrothermal activity in this previously unexplored area of a volcanic mid-ocean ridge. The team aboard... view more... (2003-07-29)

Desert woodrats switch one dietary poison for another
As the U.S. Southwest grew warmer between 18,700 and 10,000 years ago, juniper trees vanished from what is now the Mojave Desert, robbing woodrats of their favorite food.   view more (2009-04-08)

Cycles of cell death, proliferation key to liver cancer
Research at the University of California, San Diego (UCSD) School of Medicine shows that liver cancer is likely caused by cycles of liver cell death and renewal.   view more (2006-06-23)

Iron Can Have Negative Side Effects On People With Kidney Disease
More than 20 million Americans- one in nine adults- have chronic kidney disease, and most don't even know it.[1] Physicians are constantly searching for the most effective therapies to help people with end-stage renal disease (ESRD), which occurs when kidney disease has progressed and about 90% of kidney function has been lost. While iron therapy... view more... (2004-07-30)

Improving the immune system using ‘chatty’ bacteria
Certain helpful bacteria are able to communicate with cells lining the gut causing the production of chemicals that can kill off harmful microbes when they try to invade, scientists heard today (Wednesday 10 April 2002) at the spring meeting of the Society for General Microbiology at the University of Warwick.   view more (2002-04-02)

Scripps research scientists develop general-purpose method for detecting trace chemicals
Described in an advance, online publication of the journal Nature Biotechnology on February 22, 2009, the team's general method could be adapted for detecting a wide variety of compounds, including many that are relevant to diagnostic medicine and environmental work.   view more (2009-02-26)

Houseplants cut indoor ozone

Shark skin saves naval industry money
Covering ship hulls with artificial shark skin could help ships sailing smoothly. The growth of marine organisms such as barnacles on ship hulls is a major cause of increased energy costs in the naval industry. Shark skin offers a structural design that prevents this so called 'bio-fouling'.   view more (2005-07-18)

Toxic Bile Damages the Liver
Researchers at the Heidelberg University Hospital have discovered a new genetic disease that can lead to severe liver damage. Because a protective component of the bile is missing, the liver cells are exposed to the toxic components of the bile, resulting in cirrhosis of liver, a transformation of liver cells into connective tissue with a gradual... view more...

Greenland Ice Core Reveals History of Pollution in the Arctic
New research, reported this week in the online early edition of the Proceedings of the National Academy of Sciences, finds that coal burning, primarily in North America and Europe, contaminated the Arctic and potentially affected human health and ecosystems in and around Earth's polar regions.   view more (2008-08-20)

Microbes in mud flats clean up oil spill chemicals
Micro-organisms occurring naturally in coastal mudflats have an essential role to play in cleaning up pollution by breaking down petrochemical residues.   view more (2009-03-30)

Sex and lifespan linked in worms: a family of sugar-like molecules controls both
A group of scientists who set out to study sex pheromones in a tiny worm found that the same family of pheromones also controls a stage in the worms' life cycle, the long-lived dauer larva.   view more (2008-07-24)

Switchable solvents make chemical manufacturing more environmentally-friendly
Researchers from Queen's University and the Georgia Institute of Technology have discovered a new environmentally-friendly way to make chemicals for pharmaceutical and other industries, such as plastics, pesticides, dyes and fragrances.   view more (2005-08-26)

Molecules in glass houses
Trapping biological molecules such as proteins and enzymes or even whole cells in rigid structures make them easier to use for a whole range of industrial and medical applications. But combining fragile biological molecules with tough materials is difficult to do without damaging the molecules and destroying their biological activity. As well as... view more... (2001-08-01)
