The Nuclear Regulatory Commission is proposing to eliminate a foundational safety principle that has for 50 years minimized the radiation people in the United States are exposed to, and that has been adopted around the world. This comes as President Donald Trump attempts to quadruple domestic production of nuclear energy. Facilities such as nuclear plants, hospitals or academic institutions that use radioactive materials must ensure that radiation exposure is kept as low as reasonably achievable. The NRC wants to use a so-called “graded approach” instead, with several actions facilities must take depending on the amount of radiation workers could be exposed to. Maximum radiation exposure limits aren’t changing.

Jet lag threatens to turn even a dream vacation into a slog. And with peak travel season underway, millions of people may have to contend with this disorienting condition. Symptoms include gastrointestinal problems and headaches. But you can minimize its effects by adjusting what and how you eat and drink.

The Ebola outbreak in Congo has killed over 1,000 people, reaching this grim milestone nearly three times faster than the 2014-2016 epidemic. Data from Congo’s Ministry of Health shows that as of Tuesday, the outbreak, declared on May 15, has recorded 2,536 confirmed cases, including 1,033 deaths. This year's outbreak is caused by the Bundibugyo virus, a rare variant with no approved vaccines or treatments. The outbreak is mostly confined to five provinces in eastern Congo. Officials warn the peak could still be ahead, as patient zero has not been confirmed.
