Small study points to addictive effects of frequent tanning
Frequent users of tanning beds may be getting more out of the experience than darker skin, according to researchers from Wake Forest University Baptist Medical Center. view more (2006-03-29)
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)
'Reverse' tanning process could revolutionize leather industry
'Reverse' leather tanning, which essentially works backward from the point where conventional tanning ends, saves time, money and energy while drastically slashing water use and pollution, say researchers at the Central Leather Research Institute in Adyar, India. view more (2006-01-23)
New process makes diesel fuel and industrial chemicals from simple sugar
The soaring prices of oil and natural gas have sparked a race to make transportation fuels from plant matter instead of petroleum. Both biodiesel and gasoline containing ethanol are starting to make an impact on the market. view more (2006-06-30)
Parasites trigger healthy eating in caterpillars
Some parasites trigger their own destruction by altering their hosts' behavior, researchers at The University of Arizona and Wesleyan University report in Nature. view more (2005-07-29)
The presence of oxygen on carbon nanotubes enhances interaction with ammonia
Single-walled carbon nanotubes (SWNTs), which could play an important role in developing sensors against chemical threats, have enhanced interaction with ammonia because of the presence of oxygen groups on the nanotubes, researchers at Temple University have discovered. view more (2005-07-12)
NASA Study Finds Clock Ticking Slower On Ozone Hole Recovery
The Antarctic ozone hole's recovery is running late. According to a new NASA study, the full return of the protective ozone over the South Pole will take nearly 20 years longer than scientists previously expected. view more (2006-06-30)
Rutgers findings a step toward safer chemicals in labs and industry
Safe, versatile and environmentally friendly chemicals could replace hazardous, petroleum-based solvents used in science labs and industrial plants. view more (2005-10-24)
Chemotherapy can be more toxic to brain cells than to cancer cells and may cause brain damage
Drugs used to treat cancer may damage normal, healthy brain cells more than the cancer cells they are meant to target. view more (2006-11-30)
Poison dart frog mimics gain when birds learn to stay away
Studying neotropical poison dart frogs, biologists at the University of Texas at Austin uncovered a new way that the frog species can evolve to look similar, and it hinges on the way predators learn to avoid the toxic, brightly colored amphibians. view more (2006-03-09)
Human embryonic stem cells have the potential to develop into eggs and sperm in the laboratory
Scientists in the UK have proved that human embryonic stem cells can develop in the laboratory into the early forms of cells that eventually become eggs or sperm. view more (2005-06-20)
Coffee consumption linked to increased risk of heart attack for persons with certain gene variation
Individuals who have a genetic variation associated with slower caffeine metabolism appear to have an increased risk of non-fatal heart attack associated with higher amounts of coffee intake, according to a study in the March 8 issue of JAMA. view more (2006-03-08)
NASA's AURA satellite peers into Earth's ozone hole
NASA researchers, using data from the agency's AURA satellite, determined the seasonal ozone hole that developed over Antarctica this year is smaller than in previous years. view more (2005-12-07)
As ozone hole approaches annual peak, NASA scientists reveal latest information and images
In 1987, the United States joined several other nations in signing the Montreal Protocol, an international treaty designed to protect the Earth's ozone layer by phasing out the production of a number of substances believed to be responsible for ozone depletion. view more (2006-09-29)
Breast-feeding still best despite environmental chemicals in human milk
The presence of environmental chemicals in human milk does not necessarily indicate health risks for infants, according to researchers. view more (2005-09-26)
Common pesticide may reduce fertility in women
Methoxychlor (MXC), a common insect pesticide used on food crops, may interfere with proper development and function of the reproductive tract, leading to reduced fertility in women, researchers at Yale School of Medicine write in the August issue of Endocrinology. view more (2005-09-13)
Water, air and soil pollution causes 40 percent of deaths worldwide, Cornell research survey finds
About 40 percent of deaths worldwide are caused by water, air and soil pollution, concludes a Cornell researcher. Such environmental degradation, coupled with the growth in world population, are major causes behind the rapid increase in human diseases, which the World Health Organization has recently reported. view more (2007-08-14)
