NASA studies Greenland to determine how much of it is melting

NASA studies Greenland to determine how much of it is melting

Science
March 14 (UPI) -- NASA scientists are back in Greenland to find out if encroaching ocean waves are accelerating the melting on the underside of just a few unlucky glaciers, or if the ocean poses a major threat to the entirety of the island's ice. The latest research campaign is part of NASA's Oceans Melting Greenland program. Since 2016, researchers have conducted two or three field campaigns per year. Scientists continue to look for new ways to measure the effects of ocean currents and waves on the undersides of Greenland's melting glaciers. "We've seen some really surprising results that suggest the oceans have a huge effect on Greenland's biggest glaciers," Josh Willis, principal investigator on the OMG mission and a scientist at NASA's Jet Propulsion Laboratory, said in a news releas...
Researchers determine how contraction leads to hypertrophic cardiomyopathy

Researchers determine how contraction leads to hypertrophic cardiomyopathy

Health
Oct. 16 (UPI) -- Researchers have found out what leads to a form of heart attack called familial hypertrophic cardiomyopathy: Individual myosin molecules and rod-like filaments inside muscles produce less force and a lower maximum velocity of contraction than in healthy hearts. Studying transgenic rabbits with the R403Q mutation, researchers used advanced techniques such as atomic force microscopy and molecular systems to look more closely at what was going on within myosin molecules and within the filaments, called myofibrils. The findings were published Monday in the Proceedings of the National Academy of Sciences. Experiments using mice had failed to show that this was indeed the case despite genetic material resembling humans. HCM, usually an inherited condition, occurs when the heart...

No one knows how long they will live. Yet how realistic your estimate is can make or break your retirement plans. When you decide about claiming Social Security retirement benefits, one of the first questions you need to ask is how long you may live. And when you decide how much you will save toward retirement, your longevity is a key factor you need to consider. But the problem is that a lot of people fail to hit the mark. "Whenever we do our surveys, we always ask people, 'How long do you expect to live?'" said Jamie Hopkins, professor of retirement...

In the race to find a job after college, the slow and steady don't win. In fact, the quicker a graduate lands a good job after leaving school, the more likely they are to earn a better salary — in the short and long-term, according to a new study by Gallup. "Good" is self-defined by the graduate. "It doesn't matter to us what a good job means to them, it just matters to us that they found it," said Stephanie Marken, executive director of education research at Gallup, which interviewed more than 4,000 adults aged 18 and older who earned a bachelor's degree between 2010 and 2016. ...
HIV genome helps determine antibodies formed in people with the virus

HIV genome helps determine antibodies formed in people with the virus

Health
Sept. 11 (UPI) -- Researchers found that HIV itself plays a major role in determining which antibodies are formed in people, which may be important for developing a vaccine against it. A Swiss research team led by the University of Zurich and University Hospital Zurich has been searching for the factors that play a role in these antibodies' production. Their findings were published Monday in the journal Nature. HIV, which stands for human immunodeficiency virus, spreads through certain body fluids that attack the body's immune system, including T cells. Over time, these infections take advantage of a weak immune system and become acquired immunodeficiency syndrome, or AIDS. Previously identified factors that played a role in the body's immune response were: the virus load and the diversit...
