Scientists have found that a famous 2-billion-year-old chemical signature, once thought to record a massive global change in Earth’s carbon cycle, may instead have been produced by local magma, hydrocarbons, and methane-eating microbes. The discovery raises new questions about wh

A chemical that stops drywood termites from building new exoskeletons killed about 95% of colonies in testing, offering a potentially safer alternative to traditional fumigation. Because termites eventually have no choice but to molt, the treatment turns a normal stage of their l
