Tropical forests account for a third of the total carbon fixed by photosynthesis. Lianas’ increasing abundance may be driven by changing climate, increased disturbance or by more severe seasonal drought. By reducing the ability of tropical forests to accumulate and store carbon released through burning fossil fuels, lianas could cause a positive feedback loop, accelerating climate change. “This study has […]

New research suggests that high levels of BPA, a chemical in many plastics and canned food linings, might raise the risk of miscarriage in women prone to that problem or having trouble getting pregnant. While the study is not nearly enough to prove a link, experts say it does add to “the biological plausibility” that BPA might affect fertility and […]

The oil released during the BP Deepwater Horizon disaster may damage fish populations in the Gulf of Mexico for years to come. New research from the National Oceanic and Atmospheric Administration found that exposure to crude oil can cause heart defects in fish embryos—abnormalities that will likely kill many developing fish and shorten the lives of others. The study looked […]

Babies exposed to air pollution in the womb are more likely to have autism than those whose mothers spend pregnancy in clean air, according to a new study. In the largest study of its kind, UCLA researchers compared levels of air pollutants, mostly related to vehicle traffic, during pregnancy gestation periods of 7,603 children with autism and 75,635 children without […]

Worrying about everyday problems will shorten your life. A British study found that people who reported feeling even mild anxiety—the sort that distracted them, depleted their self-confidence, or occasionally kept them awake at night were 16 percent more likely to die over a 10-year period than people with no such concerns. About one in four people experiences mild anxiety, but […]

More than 100 intense Arctic wildfires have ravaged the Arctic since June, with scientists describing them as “unprecedented.” Satellite images show huge clouds of smoke billowing across uninhabited Arctic land in Greenland, Siberia and parts of Alaska. The wildfires come after the planet experienced the hottest June on record and is on track to experience the hottest July on record, […]

Thousands of pigs were found dead in rivers supplying Shanghai’s water, a grisly discovery that has drawn attention again to China’s toxic pollution, which contributes to some 700,000 deaths each year. Here are some points of concern: WASTE Tai Lake—a massive basin that holds China’s third largest body of freshwater, providing water for 30 million people—has been classified as a […]

Beijing The cloud of pollution over Beijing grew so dense this week that much of the city was rendered invisible. Hundreds of flights were grounded, auto traffic was stalled for scores of miles, and residents rushed to buy masks and air filters. Chinese officials downplayed the air-quality crisis, as usual, saying their readings showed that air pollution was “moderate.” But […]
