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.

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. 

When is it time for parents to help and when it is time to back away?

Since kids were having children of their own at age 18 a century ago it seems obvious that hovering over college-age students is not needed.  And a new paper in Journal of Child and Family Studies
 says that college students with over-controlling parents are more likely to be depressed and less satisfied with their lives. This so-called helicopter parenting style negatively affects students' well-being by violating their need to feel both autonomous and competent.

Wind energy is not very efficient and activists have turned on it because 300,000 out of 10,000,000,000 birds are killed by wind turbines each year. Without subsidies it would not exist but exist it does, only now manufacturers have had to discover physics they did not anticipate.

Wind turbine failures primarily happen because components are weakened under turbulent air flow conditions and then need to be replaced, at significant cost.

Ancient carbon trapped in Arctic permafrost is extremely sensitive to sunlight and can release climate-warming carbon dioxide gas into the atmosphere faster than previously thought if exposed to the surface when long-frozen soils melt and collapse..

They studied places in Arctic Alaska where permafrost is melting and is causing the overlying land surface to collapse, forming erosional holes and landslides and exposing long-buried soils to sunlight, and found that sunlight increases bacterial conversion of exposed soil carbon into carbon dioxide gas by at least 40 percent compared to carbon that remains in the dark.
