The Washington Post: Go To Bed! Brain Researchers Warn That Lack Of Sleep Is A Public Health Crisis.
In the screen-lit bustle of modern life, sleep is expendable. There are television shows to binge-watch, work emails to answer, homework to finish, social media posts to scroll through. We’ll catch up on shut-eye later, so the thinking goes — right after we click down one last digital rabbit hole. Brain research, which has pushed back hard against this nonchalant attitude, is now expanding rapidly, reaching beyond the laboratory and delving into exactly how sleep works in disease and in normal cognitive functions such as memory. The growing consensus is that casual disregard for sleep is wrongheaded — even downright dangerous. (Johnson, 1/24)

The New York Times: Why Six Months Seems To Be The Sweet Spot For Paid Parental Leave
As the United States has debated the issue of paid parental leave, a few employers have stood out by providing very generous terms. One has been the Bill and Melinda Gates Foundation, which in 2015 began offering parents one year of fully paid leave to spend with their babies. It turns out it was too long to be sustainable. Last week, the foundation told employees it was cutting paid parental leave by half, to six months, because yearlong leaves were impairing the work of the foundation. It will add a $20,000 stipend for new parents to spend on child care costs and family needs when they return to work. (Miller, 1/25)

The Washington Post: 2018 Was The Fourth Warmest Year On Record -- And More Evidence Of A ‘New Normal,’ Scientist Group Reports
The year 2018 is likely to have been the fourth warmest year on record, a scientific group pronounced Thursday -- and joins three other extra-hot years since 2015 that suggest a leap upward in warmth that the Earth may never return from in our lifetimes. The warmest year on record for the Earth’s land and oceans was 2016 -- by a long shot, thanks to a very strong El Nino event. That’s followed by 2017, 2015, and now 2018, said Zeke Hausfather, a research scientist with Berkeley Earth, which released the findings. (Mooney, 1/24)

CQ: Coal Industry Fought Black Lung Tax As Disease Rates Rose
While cases of black lung disease among miners were on the rise last year, coal companies and industry groups lobbied lawmakers against extending a tax program that provides a lifeline for sufferers and their families.

The Washington Post: Older, Right-Leaning Twitter Users Spread The Most Fake News In 2016, Study Finds
The notion that fake news exists in its own universe turns out to be doubly true: One universe is the realm outside truth. The other is its own seedy pocket of social media. In a new study published Thursday in the journal Science, political scientists surveyed the inhabitants of this Internet pocket around the time of the last presidential election, from Aug. 1 to Dec. 6, 2016. They found that people who shared fake news were more likely to be older and more conservative. (Guarino, 1/24)
