Bran filters chlorinated hydrocarbons and arsenic out of waste water
Compounds of arsenic and hexachlorocyclahexane (HCHs) previously occurred above all in the production of pesticides. Pesticides containing HCHs have been prohibited in Germany since the 1980s. Arsenic is still used in the semiconductor and glass industries and pollutes water and the soil in many places. Since HCHs and arsenic are carcinogenic... view more... (2002-10-11)
Acetaldehyde in alcohol -- no longer just the chemical that causes a hangover
New evidence by researchers at the Centre for Addiction and Mental Health (CAMH) and researchers in Germany shows that drinking alcohol is the greatest risk factor for acetaldehyde-related cancer. Heavy drinkers may be at increased risk due to exposure from multiple sources. view more (2009-03-19)

New Insight Into Aluminium
Aluminium is a metal widely used in industry; therefore the more that is known about it, the more effectively it can be used. Researchers at Ris'¸ National Laboratory in Denmark and the European Synchrotron Radiation Facility (ESRF) in France have filmed in 3D the changes in the bulk of deformed aluminium after annealing. Thanks to the uniqueness... view more... (2004-07-09)
The rain in Spain falls mainly "¦ at the coast
If you're thinking about heading to Spain for some late autumn sunshine, think again. Researchers at the University of East Anglia (UEA) have discovered that the number of wet days in Spain is on the increase. Dr Clare Goodess, of UEA's Climatic Research Unit, studied forty years worth of rainfall data for Spain (1958-1997) and found that although... view more... (2002-11-11)
