PETA International Science Consortium disappointed in denial of Dow appeal

( People for the Ethical Treatment of Animals ) The PETA International Science Consortium is extremely disappointed that the European Chemicals Agency Board of Appeal has upheld a decision that requires Dow Benelux B.V. to conduct a prenatal developmental toxicity study in rats. The study will use approximately 1,160 animals and expose pregnant rats and their unborn pups to the substance dipropylene glycol methyl ether acetate in order to comply with the European Community's Regulation on the Registration, Evaluation, Authorisation and Restriction of Chemicals.

Metamorphosis of moon's water ice explained

( University of New Hampshire ) Using data gathered by NASA's Lunar Reconnaissance Orbiter mission, scientists believe they have solved a mystery from one of the solar system's coldest regions -- a permanently shadowed crater on the moon. They have explained how energetic particles penetrating lunar soil can create molecular hydrogen from water ice. The finding provides insight into how radiation can change the chemistry of water ice throughout the solar system.

Renewed hope in a once-abandoned cancer drug class

( American Chemical Society ) Could drugs that block the body's system for repairing damage to the genetic material DNA become a boon to health? As unlikely as it may seem, those compounds are sparking optimism as potential treatments for ovarian and breast cancers driven by a mutation in BRCA. The compounds, termed PARP inhibitors, are the topic of the cover story in the current edition of Chemical & Engineering News. C&EN; is the weekly newsmagazine of the American Chemical Society, the world's largest scientific society.
