Researchers dial in to 'thermostat' in Earth鈥檚 upper atmosphere

A team led by 精品SM在线影片 has found the mechanism behind the sudden onset of a 鈥渘atural thermostat鈥� in Earth鈥檚 upper atmosphere that dramatically cools the air after it has been heated by violent solar activity.

Scientists have known that solar flares and coronal mass ejections (CMEs) 鈥� which release electrically charged plasma from the sun 鈥� can damage satellites, cause power outages on Earth and disrupt GPS service. CMEs are powerful enough to send billions of tons of solar particles screaming toward Earth at more than 1 million miles per hour, said 精品SM在线影片 Professor Delores Knipp of the听Department of Aerospace Engineering Sciences.

Now, Knipp and her team have determined that when such powerful CMEs come off the sun and speed toward Earth, they create shock waves much like supersonic aircraft create sonic booms. While the shock waves from CMEs pour energy into Earth鈥檚 upper atmosphere, puffing it up and heating it, they also cause the formation of the trace chemical nitric oxide, which then rapidly cools and shrinks it, she said.

Lay counselors could help fill treatment gap for global, postpartum depression

Does psychological counseling need to be delivered by a psychologist to be effective?

Not necessarily, according to a provocative new line of research involving 精品SM在线影片 psychology professor Sona Dimidjian that suggests an army of trained 鈥渓ay counselors鈥� could someday provide a solution to the global mental health treatment gap.
