Specialists work to remove toxic pesticides, including lindane and sulphur, in Porto Romano, Albania in 2006. The UN said that Lindane, an insecticide used in farming and to treat woodworm, was among nine highly toxic chemicals added to a "dirty dozen" of dangerous substances on an international red list. The UN said Thursday an insecticide [...]
NYU and St. Petersburg State University chemists have discovered a wholly new phenomenon for crystal growth–a crystal that continually changes its shape as it grows. (Credit: Image courtesy of New York University) ScienceDaily (July 17, 2010) — Chemists from New York University and Russia's St. Petersburg State University have created crystals that can twist and [...]
Thomas Bobik, professor of biochemistry, biophysics and molecular biology, along with David Gogerty, a doctoral student, invented a process for manufacturing isobutene (isobutylene) by identifying a new, natural enzyme that produces the fuel organically. They believe that once more research is completed, there could be huge benefits to the biofuels industry. (Credit: ISU photo by [...]
California regulators aim to fill in the gap on chemicals that have not been evaluated for toxicity TAKING INVENTORY: The ecological effects thousands of chemicals used in commerce today are unknown, experts say. ISTOCKPHOTO/kajetan As hundreds of thousands of gallons of dispersants were dropped into the Gulf of Mexico to control the oil spill, Philip [...]
Chemist Robert Perry checks a flask containing an ingredient — similar to those in shampoos — that shows promise for capturing carbon dioxide, the main "greenhouse" gas linked to global warming.

Chemists have developed the most potent homogeneous catalyst known for water oxidation, considered a crucial component for generating clean hydrogen fuel using [...]
The reddish glow from the city lights of Boulder, Colo., is the result in part of the light being scattered by haze particles. UW scientists have discovered unexpected chemistry involving the pollutants that make up the haze. (Credit: Phil Armitage) ScienceDaily (Mar. 11, 2010) — The smell of sea salt in the air is a [...]
ScienceDaily (Jan. 27, 2010) — A study published this week in the journal Proceedings of the National Academy of Sciences (PNAS) provides new information about the rates at which three of the most powerful greenhouse gases are destroyed by a chemical reaction that takes place in the upper atmosphere. Georgia Tech researchers work in their [...]
ScienceDaily (Jan. 19, 2010) — Scorpions deliver a powerful, paralyzing venom — a complex cocktail of poisonous peptides — that immobilize animal prey on the spot. Some of the toxins in this cocktail damage only insects, which is why a Tel Aviv University researcher is harnessing them to create a safe and ecologically sound pesticide. [...]
