Chronic short sleep is associated with increased risk of clogged arteries, heart disease, and thus increased morbidity and mortality. New research in Experimental Physiology may have figured out why lack of sleep increases susceptibility to heart disease, and allowing doctors to identify the patients who might need to change their habits before they develop disease.

Air pollution kills. In the United States, 1 of every 25 deaths occurs prematurely because of exposure to outdoor air pollution.

Irvine, Calif., May 2, 2019 - Water polo athletes take note: A new study by University of California, Irvine researchers maps out the frequency of head injuries in the sport and reveals which positions are the most vulnerable.

The first-of-its-kind report, which tracked several dozen male collegiate water polo players over three seasons, was published today in PLOS One, a peer-reviewed, open-access scientific journal.

PHILADELPHIA - A study of a blood pressure drug does not show any benefit for people with Parkinson's disease, according to findings released today that will be presented at the American Academy of Neurology's 71st Annual Meeting in Philadelphia, May 4 to 10, 2019.

The drug isradipine had shown promise in small, early studies and hopes were high that this could be the first drug to slow the progression of the disease.

The biblical King Balak may have been a historical figure, according to a new reading of the Mesha Stele, an inscribed stone dating from the second half of the 9th century BCE.

A new study by American Cancer Society researchers finds medical financial hardship is very common among people in the United States, with more than half reporting problems with affordability, stress, or delaying care because of cost. The study, appearing early online in the Journal of General Internal Medicine, estimates more than 100 million people in the U.S. experience medical financial hardship.

A new study in The Auk: Ornithological Advances suggests that some birds prioritize social information over visual evidence when making breeding choices.

WEST LAFAYETTE, Ind. - Precise measurements are critical to the discovery, development and usage of medications. Major financial and scientific decisions within pharmaceutical companies are informed by the outcomes of chemical and biological analyses. Even slight measurement variations can add risk and uncertainty in these high-stakes decisions.

A new study published April 30 in the Proceedings of the National Academy of Sciences identified three factors critical in the rise of mammal communities since they first emerged during the Age of Dinosaurs: the rise of flowering plants, also known as angiosperms; the evolution of tribosphenic molars in mammals; and the extinction of non-avian dinosaurs, which reduced competition between mammals and other vertebrates in terrestrial ecosystems.

People living in the most populous, low-income areas in New Jersey with the highest risk for opioid overdoses have less access to the potentially life-saving opioid reversal drug naloxone, Rutgers researchers find.

A study in mice shows that selectively removing cells that are no longer dividing from the brains of mice with a form of Alzheimer's disease can reduce brain damage and inflammation, and slow the pace of cognitive decline. These findings, say researchers, add to evidence that such senescent cells contribute to the damage caused by Alzheimer's disease in people.

An increasingly popular feature of modern video games is attracting gamers who share the beliefs and behaviours of problem gamblers, new UBC research has found.

Gamers who are drawn to "loot boxes"--randomly generated prizes of undisclosed value that can be attained or purchased within a game--bear a closer resemblance to problem gamblers than they do to problem gamers, according to the study published April 16 in Addictive Behaviors.

Hydrogen is a critical component in the manufacture of thousands of common products from plastic to fertilizers, but producing pure hydrogen is expensive and energy intensive. Now, a research team at Princeton University has harnessed sunlight to isolate hydrogen from industrial wastewater.

In a paper published Feb. 19 in the journal Energy & Environmental Science, the researchers reported that their process doubled the currently accepted rate for scalable technologies that produce hydrogen by splitting water.

ITHACA, N.Y. - Cornell University-led research reports that two local fungal pathogens could potentially curb an invasive insect that has New York vineyard owners on edge.

The spotted lanternfly feeds on more than 70 plant species, including grape vines and apple trees.

In recent years, the market for direct-to-consumer genetic testing has exploded. The number of people who used at-home DNA tests more than doubled in 2017, most of them in the U.S. About 1 in 25 American adults now know where their ancestors came from, thanks to companies like AncestryDNA and 23andMe.
