Small biocides companies face uncertain fate

Chemistry World | 24

Biocides are among the most tightly regulated groups of chemicals in Europe. After all, anything designed to kill or deter microorganisms could pose a danger to the environment or human health. But companies are warning that strict EU law, aimed at ensuring the disinfectants, preservatives and pest control chemicals we use are safe, has an unwanted side-effect. Small and medium-sized enterprises (SMEs) cannot cope and are leaving the market, with potentially drastic consequences for the sector.

Critics pan EPA plan for evaluating studies of toxic chemicals

Science | 

Academic scientists and advocacy groups are urging the Environmental Protection Agency (EPA) to withdraw and rewrite proposed guidelines for determining which scientific findings to use when evaluating the safety of toxic chemicals. Critics say that if adopted, the guidance will allow regulators to exclude high-quality health and risk studies for “ridiculous” reasons, favor industry-backed research, and prevent EPA from considering academic studies that rest on innovative methods.

Mosquito spit can bust blood clots in mice

Science | 10 April

Does your blood run thick? A bit of mosquito saliva might one day be just what the doctor ordered. That’s because scientists have found a new way to reinvigorate anticlotting factors in mosquito spit in the lab. The modified blood thinner has so far only been tested in mice; if it ever works in humans, it could help prevent—and even treat—the blood clots that can lead to hemorrhaging or thrombosis.
