A new brutal winter storm will rampage across the United States over the next couple of days, with more than 100 million Americans in its path as it tracks from the southern Plains to the East Coast. From Minnesota to Texas, utility companies have implemented rolling blackouts to ease the burden on power grids straining to meet extreme demand for heat and electricity as record low temperatures were reported in city after city. More than 30 people have died because of the intense cold and a series of storms that moved from coast to coast since the weekend.

The mission? Find signs of life.

But before it can begin roving its targeted landing site at a breakneck 0.1 mph, Perseverance has to pull off a series of risky landing maneuvers all by itself.

Life expectancy in the United States dropped to its lowest level in 15 years – and even lower for Black Americans and Latinos – during the first half of the coronavirus pandemic, a new study released Thursday finds. Data through June 2020 shows life expectancy at birth for the total U.S

population fell from 2019 by a year to 77.8 years, the lowest since 2006, according to researchers at the Centers for Disease Control and Prevention’s National Center for Health Statistics. Life expectancy for Black populations declined the most from 2019 – by 2.7 years, to 72 years – the lowest level since 2001

Latinos experienced the second-biggest decline, falling 1.9 years since 2019 to a life expectancy of 79.9 years, lower than when it was first recorded in 2006.
