Heart attacks reoccurred more frequently in younger patients with several modifiable risk factors, including smoking and high blood pressure. Researchers on the new study, presented at the American College of Cardiology Asia Conference 2018 in Shanghai, suggested secondary preventive programs for younger patients should target modifiable risk factors.
NEW YORK, December 1, 2018 - Researchers conducting a 5-year-long study examining snow cover in a northern hardwood forest region found that projected changes in climate could lead to a 95 percent reduction of deep-insulating snowpack in forest areas across the northeastern United States by the end of the 21st century. The loss of snowpack would likely result in a steep reduction of forests' ability to store climate-changing carbon dioxide and filter pollutants from the air and water.
The English idiom "highbrow," derived from a physical description of a skull barely able to contain the brain inside of it, comes from a long-held belief in the existence of a link between brain size and intelligence.
For more than 200 years, scientists have looked for such an association. Begun using rough measures, such as estimated skull volume or head circumference, the investigation became more sophisticated in the last few decades when MRIs offered a highly accurate accounting of brain volume.
A simple molecule in the atmosphere that acts as a "detergent" to breakdown methane and other greenhouse gases has been found to recycle itself to maintain a steady global presence in the face of rising emissions, according to new NASA research. Understanding its role in the atmosphere is critical for determining the lifetime of methane, a powerful contributor to climate change.
If you ever find yourself staring down a manta ray, you'll probably notice two things right away: the massive, flapping fins that produce the shark cousin's 20-foot wingspan and the two fleshy growths curling out of its head that give it the nickname "devil ray." A new San Francisco State University study shows that these two very different features have the same origin -- a discovery that reflects an important lesson for understanding the diversity of life.
Rockville, Md. (November 29, 2018)--New research suggests that curcumin, a main ingredient in curry, may improve exercise intolerance related to heart failure. The study is published ahead of print in the Journal of Applied Physiology.
Reef fisheries can continue to provide food and income despite corals being lost to climate change, according to new research conducted in the Seychelles.
The unexpected results of a 20-year study into reef fisheries published in the journal Nature Ecology and Evolution this week showed fisheries being maintained despite extreme coral bleaching. Remarkably, rapid proliferation of fishes with low dependence on corals led to catches remaining stable or even increasing.
But the results also showed fishing success was 'patchy' and more dependent on fewer species.
IIASA researchers have contributed to a major new report in The Lancet medical journal looking at the effects of climate change on human health, and the implications for society.
GAINESVILLE, Fla. --- About 56 million years ago, on an Earth so warm that palm trees graced the Arctic Circle, a mouse-sized primate known as Teilhardina first curled its fingers around a branch.
The earliest-known ancestor of modern primates, Teilhardina's close relatives would eventually give rise to today's monkeys, apes and humans. But one of the persistent mysteries about this distant cousin of ours is where it originated.
People living in Kansas, Nebraska and other states in the Plains are no strangers to tornadoes and hail storms - among the most costly and dangerous severe weather threats in the United States.
Meteorologists and computer models do a good job forecasting severe thunderstorm activity up to a week in advance. Scientists can also read long-term, seasonal signals of severe weather months in advance.But there's a middle ground - a prediction lead time of about 2 to 5 weeks - that's sorely lacking in current forecasting capabilities.
