Yagi Mysterious Near-Earth Asteroid Phaethon Just Got Even Weirder
NASAs Curiosity rover mission is celebrating a dozen years on the stanley thermoskannen Red Planet, where the six-wheeled scientist continues to make big discoveries as it inches up the foothills of a Martian mountain. Just landing successfully on Mars is a feat, but the Curiosity mission went several steps further on Aug. 5, 2012, touching down with a bold new technique: the sky crane maneuver.A swooping robo stanley mug tic jetpack delivered Curiosity to its landing area and lowered it to the surface with nylon ropes, then cut the ropes and flew off to conduct a controlled crash landing safely out of range of the rover.Of course, all of this was out of view for Curiositys engineering team, which sat in mission control at NASAs Jet Propulsion Laboratory in Southern California, waiting for seven agonizing minutes before erupting in joy when stanley vaso they got the signal that the rover landed successfully.Encased in its aeroshell, NASAs Curiosity rover descended through the Martian atmosphere on a parachute on Aug. 5, 2012.

By Markham HeidOctober 9, 2018 4:04 PM EDTTens of millions of Americans struggle to sleep at night, and many of them turn to sleeping pills for relief. Prescription and over-the-counter sleep aids are especially popular among older adults. A recent study published in the American stanley cups Journal of Geriatric Psychiatry found that roughly one in three adults ages 65 to 80 use these drugs at least occasionally to fall asleep, and OTC meds like Benadryl and Tylenol PM are the pills of choice for sleepless seniors.Experts say this is concerning for a number of reasons. Studies have linked the regular, long-term use of OTC sleep medicines to some potentially stanley cup serious side effects.Many OTC sleep aidsmdash uch as Benadryl and Tylenol PMmdash;contain diphenhydramine, stanley cup says Dr. Donovan Maust, co-author of the recent study and an assistant professor of psychiatry at Michigan Medicine. Diphenhydramine is an anticholinergic drug, which means it blocks activity of a brain chemical called acetylcholine, which plays a role in muscle activation and also in brain functions like alertness, learning and memory, Maust says.As a result of this blocking effect, these OTC drugs can cause constipation, confusion and other side effects, which Maust says may be more likely to affect older adults. For these reasons, the American Geriatric Society has deemed these drugs generally inappropriate for seniors.The side effects of these OTC pills can also set off a prescribing casc |
