Meal kit delivery services are here and they seem to be flourishing.

According to the Meal Kit Delivery Services in the U.S. report from market research publisher Packaged Facts, meal kit delivery services have exploded over the past few years by bridging the space between home-cooked meals and takeout. The services offer people a convenient way to cook at home without having to do the meal planning and grocery shopping. Online portals let consumers order meals ahead from picture menus and the services deliver the pre-measured fresh ingredients along with recipes to their doorstep to help them cook meals at home.

ANN ARBOR, Mich -- Nearly half of parents whose child had leftover pain medication from a surgery or illness say they kept the prescription opioids at home -- representing a potential problem down the line.

Parents whose child's provider discussed what to do with the pills, however, were far more likely to dispose them properly, according to a report from the C.S. Mott Children's Hospital National Poll on Children's Health.

CHAMPAIGN, Ill. -- A new study reveals that police recruits and experienced officers are more likely than others to subscribe to colorblind racial beliefs -- the notion that they - and people in general -- see no differences among people from different racial groups and treat everyone the same.

The findings appear in the journal Race and Social Problems.

The U.S. police force is roughly 75 percent white and male, said University of Illinois anthropology professor Cris Hughes, who led the research with colleagues in anthropology, psychology, advertising and the U. of I. Police Training Institute.

Scientists have found evidence of a huge asteroid that struck the Earth early in its life with an impact larger than anything humans have experienced.

Tiny glass beads called spherules, found in north-western Australia were formed from vaporised material from the asteroid impact, said Dr Andrew Glikson from The Australian National University (ANU).

"The impact would have triggered earthquakes orders of magnitude greater than terrestrial earthquakes, it would have caused huge tsunamis and would have made cliffs crumble," said Dr Glikson, from the ANU Planetary Institute.

As climatologists closely monitor the impact of human activity on the world's oceans, researchers at the Georgia Institute of Technology have found yet another worrying trend impacting the health of the Pacific Ocean.

A new modeling study conducted by researchers in Georgia Tech's School of Earth and Atmospheric Sciences shows that for decades, air pollution drifting from East Asia out over the world's largest ocean has kicked off a chain reaction that contributed to oxygen levels falling in tropical waters thousands of miles away.

SAR11 are the most abundant plankton in the world's oceans. They are also a massive source of two sulfur gases that play important roles in the Earth's atmosphere.
