Science Magazine – United States adopts major chemical safety overhaul
The U.S. Senate yesterday unanimously approved a major overhaul of the nation’s primary chemical safety law—marking one of the last steps in a decades-long reform effort. The House of Representatives on 24 May overwhelmingly approved the rewrite of the Toxic Substances Control Act (TSCA), which governs how industrial chemicals are tested and regulated. The legislation now moves to President Barack Obama for signing.
The measure—H.R. 2576, named for the late Senator Frank Lautenberg (D–NJ), a long-time TSCA reform champion—is perhaps the most far-reaching and influential environmental statute passed by Congress since the body updated the Clean Air Act in 1990. The measure aims to make chemical safety reviews more science-based, and includes provisions designed to reduce the use of animals in chemical testing and promote the study of so-called cancer clusters.

Associated Press via The New York Times – Latest Ebola Outbreak in Liberia Is Now Over, UN Says
The World Health Organization has declared Liberia’s latest Ebola outbreak over, the fourth such announcement since the virus was first reported there. Liberia is the last country to receive the declaration, made 42 days after tests showed the last infected person no longer had the virus. Liberia’s health ministry said it now enters a 90-day heightened surveillance period. The Ebola outbreak was first declared over in Liberia in May 2015, but new cases emerged, resetting the clock three times. More than 4,800 people have died in Liberia, and more than 11,300 mostly in West Africa, since December 2013.

The Sacramento Bee – AM Alert: New California Tobacco Age Limits Go Into Effect
Yesterday a doctor couldn’t legally grant a terminally ill patient’s request for a prescription that would end their lives. Starting today, a doctor can. Yesterday, a 20-year-old could walk into a gas station and buy a pack of cigarettes. Today, no dice. California’s physician-assisted suicide End of Life Option Act will allow physicians to write prescriptions for patients who are given no more than six months to live by their doctors. Doctors aren’t required to grant the prescription, and are free to opt out of the law. Experts in the field say that there’s no way to predict how many terminally ill people might take advantage of the new law. New tobacco rules, meanwhile, increase the smoking age from 18 to 21 today. In addition, e-cigarettes and vaping are now covered by traditional tobacco regulations. The bills survived a grueling battle in the Legislature amid intense opposition from the tobacco industry.

WSTP – Most antidepressants ineffective in teens, study finds
Most antidepressants on the market are ineffective for children and teens with major depressive disorder, and some may be unsafe for young patients, according to new research published in The Lancet. The findings show that out of 14 antidepressants, only fluoxetine (sold under brand names Prozac and Sarafem) was more effective at relieving symptoms of depression in young people than a placebo pill. In contrast, taking venlafaxine (Effexor) was associated with an increased risk of suicidal thoughts and suicide attempts when compared to a placebo and five other antidepressants.
