A long-term study led by the University of Washington and the University of California, Berkeley tracked how hundreds of species in the Carrizo Plain National Monument fared during the historic drought that struck California from 2012 to 2015.
Deforestation is suspected to have contributed to the mysterious collapse of Mayan civilization more than 1,000 years ago. A new study shows that the forest-clearing also decimated carbon reservoirs in the tropical soils of the Yucatan peninsula region long after ancient cities were abandoned and the forests grew back.
Researchers at the George Washington University have published a study in Nature Climate Change that for the first time analyzes all US climate change lawsuits over a 26-year period.
The study examined individual- and state-level factors associated with texting while driving among teens from 35 states. Researchers found that nearly two in five teen drivers age 14 years and older had texted while driving at least once in the month prior to the survey.
Tobacco use is the leading preventable cause of death in the world and encompasses a variety of products, including cigarettes, e-cigarettes and smokeless tobacco. Combustible cigarettes remain the most common tobacco product used by US adults, but studies have shown no level of cigarette consumption is safe. A new review -- published today in the Journal of the American College of Cardiology -- examines policies to achieve complete cigarette abstinence as part of efforts to reduce the risk of heart disease.
Militarized policing does not lead to less violent crime or less violence against police officers, according to a new study led by Princeton University. The study also shows that militarized police units are more often deployed in communities of color.
America's drug problem may be even worse than officials realize. And illicit drugs are consumed at a higher rate during celebratory events. Those are just two of the conclusions scientists have drawn from recent studies of drug residues in sewage. The researchers will present their results today at the 256th National Meeting & Exposition of the American Chemical Society.
Policymakers and public health experts have long recognized the harm that can come to fetuses if women use drugs during pregnancy. As U.S. states legalize marijuana and as governmental attention focuses on the 'opioid crisis,' state policies pertaining to drug use during pregnancy are increasingly important. A new study examines the scope of state policies targeting drug use during pregnancy, how they have evolved, and how they compare to policies related to alcohol use during pregnancy.
Researchers have developed a system using artificial intelligence that can edit the facial expressions of actors to accurately match dubbed voices, saving time and reducing costs for the film industry.
Scientists have found that sunscreen from bathers releases significant quantities of polluting TiO2 (titanium dioxide) into the sea. This has the potential to harm marine life. This work, which comes from research on beaches in the South of France, was presented at the Goldschmidt geochemistry conference in Boston (see below).
