Thirty years after scientists coined the term “hygiene hypothesis” to suggest that increased exposure to microorganisms could benefit health, University of Colorado Boulder researchers have identified an anti-inflammatory fat in a soil-dwelling bacterium that may be responsible.
The discovery, published Monday in the journal Psychopharmacology, may at least partly explain how the bacterium, Mycobacterium vaccae, quells stress-related disorders. It also brings the researchers one step closer to developing a microbe-based “stress vaccine.”
“We think there is a special sauce driving the protective effects in this bacterium, and this fat is one of the main ingredients in that special sauce,” said senior author and Integrative Physiology Professor Christopher Lowry.

" Today, there is not a single county in the United States where someone making minimum wage can afford a two-bedroom apartment. In Atlanta, according to the National Low Income Housing Coalition’s annual Out of Reach report,
the “housing wage” needed to pay for a modest two-bedroom unit is
$21.27 an hour. (Georgia’s minimum wage is $5.15 an hour.)
In Boston, a tenant earning minimum wage would have to log 141 hours a week
to afford the same residence. In San Francisco, it’s 203 hours,
or the equivalent of five full-time jobs."

Trees can play a huge role in the health of people living in cities, but across the country, cities are losing millions of trees year after year. And many poor urban neighborhoods — often home to a city's most vulnerable — are starting at a disadvantage.
"If we show you a map of tree canopy in virtually any city in America, we're also showing you a map of income," says Jad Daley, president and CEO of the nonprofit American Forests. "And in many cases we're showing you a map of race and ethnicity."
