Fire Safety without Harm

Fire Safety without Harm

Last week, scientists and regulators from more than 20 countries gathered in San Francisco to discuss the latest research on flame retardants. The conference lasted four days, but the theme of the meeting was clear from just a few talks: Do we need toxic chemicals to achieve fire safety?

Playing Whack-a-Mole with Flame Retardants

Playing Whack-a-Mole with Flame Retardants

Countless consumer products sold in California contain a flame retardant flagged as a possible carcinogen nearly 35 years ago. As of this week, finally, they must carry a warning that the chemical causes cancer. But is it enough when manufacturers simply replace one toxic chemical with another?

 
Creative Use of a Cancer Mutation May Improve Nylon Production

Creative Use of a Cancer Mutation May Improve Nylon Production

Chemists want to reengineer metabolic proteins and pathways in microbes so they can convert sugar into commodity chemicals. Now a mutant protein found in cancer cells provides clues to help scientists improve a protein that could help microbes create a precursor to nylon. In science, as in so much of life, inspiration can come from unusual places.

 
West Coast a Test Bed for Ocean Acidification

West Coast a Test Bed for Ocean Acidification

Scientists say the waters off the West Coast could be hit hard by ocean acidification, but thanks to the natural conditions, it's a good place to study how ocean species might adapt.

NASA's Roving Robotic Chemist Will Collect Clues For Life on Mars

Scientists are looking for elements and molecules that signify life as we know it. But even if they don’t find those molecules, minerals contain important information about the Martian environment. That could help scientists determine if life could have survived on the planet.

 
Prescription Drug Disposal: Who Should Foot the Bill?

Prescription Drug Disposal: Who Should Foot the Bill?

A new ordinance in Alameda County requires the pharmaceutical industry to pay for disposal of extra medicine. The regulation is part of a larger movement to shift responsibility for waste disposal from local governments to companies that make products like paint, medicine and batteries.
