New satellite images show that the ozone hole over Antarctica in 2012 was the smallest seen in the past decade. Long-term observations show that Earth’s ozone has been strengthening. The ozone sensor on Europe’s MetOp weather satellite continues the long-term monitoring of atmospheric ozone started by its predecessors on the ERS-2 and Envisat satellites. 

Genome sequences of seven well-studied ant species give researchers a detailed look at molecular mechanisms - including what may be a basis for complex behavioral differences in two worker castes in the Florida carpenter ant, Camponotus floridanus - basically, epigenetics. 

Which is more important, feeling close to your romantic partner or whether you are as close as you want to be, even if that's really not close at all? 

Outside the social sciences, the answer is obvious. But in social psychology, it is a paper in time for Valentine's Day. Let's go to the surveys.

New data from NASA's Chandra X-ray Observatory suggest a highly distorted supernova remnant  called W49B may contain the most recent black hole formed in the Milky Way galaxy.

W49B
appears to be the product of a rare explosion in which matter is ejected at high speeds along the poles of a rotating star and is about a thousand years old (as seen from Earth) and is located about 26,000 light-years away. 

Usually when a massive star runs out of fuel, the central region of the star collapses, triggering a chain of events that quickly culminate in a supernova explosion. Most of these explosions are generally symmetrical, with the stellar material blasting away more or less evenly in all directions.

In a recent JAMA article,
2008 National Survey of Mental Health Treatment Facilities
data of psychiatric hospitals, residential treatment centers and freestanding outpatient clinics or partial-care and multiservice mental health groups found that only 63 percent of U.S. counties have at least one mental health facility that provides outpatient treatment for youth. 

Less than half of U.S. counties have a mental health facility with special programs for youth with severe emotional disturbance. The gaps in infrastructure are even larger in rural communities, where less than half even have one mental health facility that provides outpatient care and only one-third has outpatient facilities with specific programs for youth with severe illness.
