La Jolla, Calif., April 9, 2018 - Obesity is the second-leading preventable cause of cancer and represents one of the greatest threats to global human health. But it has not been clear exactly how whole-body metabolism affects tumor formation. In particular, the molecular mechanisms by which fat cells communicate with tumor tissue remain poorly understood.
"There is a paradox at play when it comes to atrial fibrillation in the Latino population," said Dr. Dawood Darbar.
"While Latino individuals are less likely to develop atrial fibrillation than whites, despite having a higher burden of risk factors, they are more likely to suffer complications if the condition does develop," said Darbar, professor medicine and pharmacology in the University of Illinois at Chicago College of Medicine.
WACO, Texas (April 9, 2018) - Have you ever bought a gift for a friend, simply because it's a gift that you would like yourself?
If so, that was likely a time that you projected your own attitudes onto your friend, assuming your friend shared your preferences. Such activity is called "social projection" and is the focus of new marketing research from Baylor University's Hankamer School of Business.
The genome is the body's instruction manual. It contains the raw information -- in the form of DNA -- that determines everything from whether an animal walks on four legs or two, to one's potential risk for disease. But this manual is written in the language of biology, so making sense of all that it encodes has proven challenging. Now, Columbia University researchers have developed a computational tool that shines a light on the genome's most hard-to-translate segments.
A new method to sensitively measure the structure of molecules has been demonstrated by twisting laser light and aiming it at miniscule gold gratings to separate out wavelengths.
The technique could potentially be used to probe the structure and purity of molecules in pharmaceuticals, agrochemicals, foods and other important products more easily and cheaply than existing methods.
BOZEMAN -- For years, researchers have known that it is hard to attract and keep women and some minorities in science, technology, engineering and math - or STEM - fields. Now, a Montana State University researcher has found that the same problem applies to sexual minorities.
Mobile apps designed to help parents keep their children safe from online predators may actually be counterproductive, harming the trust between a parent and child and reducing the child's ability to respond to online threats, conclude two new studies from the University of Central Florida.
According to the national Crimes Against Children Research Center, 23 percent of youth have experienced accidental exposure to internet pornography. Another 11 percent have been victims of online harassment and 9 percent report receiving unwanted sexual solicitations online.
Dozens of giant footprints discovered on a Scottish island are helping shed light on an important period in dinosaur evolution.
The tracks were made some 170 million years ago, in a muddy, shallow lagoon in what is now the north-east coast of the Isle of Skye.
Most of the prints were made by long-necked sauropods - which stood up to two metres tall - and by similarly sized theropods, which were the older cousins of Tyrannosaurus rex.
CHAMPAIGN, Ill. -- Latinos who are the most optimistic are more likely to have healthy hearts, suggests a new study of more than 4,900 people of Latino/Hispanic ancestry living in the U.S.
After a great mass extinction shook the world about 252 million years ago, animal life outside of the ocean began to take hold. The earliest mammals entered the scene, and reptiles -- including early dinosaurs -- lived on Pangea, the name given to the giant landmass in which all of the world's continents were joined as one.
WINSTON-SALEM, N.C. - March 28, 2018 - Scientists at Wake Forest Baptist Medical Center and the University of Southern California (USC) have demonstrated the successful implementation of a prosthetic system that uses a person's own memory patterns to facilitate the brain's ability to encode and recall memory.
Someone who starts mining a crypto-currency shortly after it is listed on exchanges can potentially earn higher returns than average. But a speculator who enters the market shortly after the currency is listed might potentially earn lower returns.
A University of Oklahoma research study, led by Professor Xiangming Xiao, reveals the divergent trends of open surface water bodies in the contiguous United States from 1984 to 2016, specifically, a decreasing trend in the water-poor states and an increasing trend in the water-rich states. Surface water resources are critical for public water supply, industry, agriculture, biodiversity and ecosystem services.
MEDFORD/SOMERVILLE, Mass. (March 26, 2018) -- Researchers at Tufts University have created a genetically modified yeast that can more efficiently consume a novel nutrient, xylose, enabling the yeast to grow faster and to higher cell densities, raising the prospect of a significantly faster path toward the design of new synthetic organisms for industrial applications, according to a study published today in Nature Communications.
After the introduction of tamper-resistant oxycodone in Australia, dispensing rates for higher-strength formulations decreased for people younger than 65 years, but there was no change in older adults, according to new research in CMAJ (Canadian Medical Association Journal).
