Physically active white men at high risk for plaque buildup in arteries
Mon, 16 Oct 2017 14:48:46 EDT
White men who exercise at high levels are 86 percent more likely than people who exercise at low levels to experience a buildup of plaque in the heart arteries by middle age, a new study suggests.
Tweeting rage: How immigration policies can polarize public discourse
Mon, 16 Oct 2017 14:48:44 EDT
A study of tweets in the months before and after the 2010 passage of Arizona's "show me your papers" law, findings showed that the average tweet about Mexican immigrants and Hispanics, in general, became more negative. Researchers said the social media data was useful in determining whether people had changed their attitudes about immigrants as a result of the law or whether they had begun behaving differently.
Clues to the Innate Drug Resistance of a Cocoa-Fermenting Pathogen
Mon, 16 Oct 2017 14:48:42 EDT
At first glance, the yeast Candida krusei seems as innocuous as microbes come: it’s used for fermenting cocoa beans and gives chocolate its pleasant aroma. But it’s increasingly being found as a pathogen in immunocompromised patients — and C. krusei infections aren’t always easy to cure.
Women in science ask fewer questions than men, according to new research
Mon, 16 Oct 2017 14:24:46 EDT
Stereotypes suggest that women love to talk, with some studies even finding that women say three times as much as men. But, new research shows there is an exception to this rule: professional STEM events, which could be indicative of the wider problem of gender inequality in the field.
Brain training shows promise for patients with bipolar disorder
Mon, 16 Oct 2017 13:27:56 EDT
Computerized brain training can result in improved cognitive skills in individuals with bipolar disorder, researchers have discovered for the first time.
Catch a fleeting kilonova
Mon, 16 Oct 2017 13:26:54 EDT
Alerted by the first-ever gravitational waves caused by two neutron stars merging, astronomers detect the resulting optical flash.
Toward efficient high-pressure desalination
Mon, 16 Oct 2017 13:26:50 EDT
One of the biggest operational challenges for desalination plants is the fouling of membranes by microbes. New research suggests a novel approach to reducing the rate of fouling, and thus improving desalination plant efficiency.
Break the attachment before selling your stuff
Mon, 16 Oct 2017 13:26:48 EDT
Ever tried to sell something you've owned for a while on Craigslist and found that no one is willing to pony up what you're asking? It's because you're asking too much.
Chemical treatment improves quantum dot lasers
Mon, 16 Oct 2017 13:26:44 EDT
One of the secrets to making tiny laser devices such as opthalmic surgery scalpels work even more efficiently is the use of tiny semiconductor particles, called quantum dots. In new research the ~nanometer-sized dots are being doctored, or 'doped,' with additional electrons, a treatment that nudges the dots ever closer to producing the desired laser light with less stimulation and energy loss.
Family members play important role in managing chronic illness
Mon, 16 Oct 2017 13:26:42 EDT
Family members often play an important role in managing chronic illnesses, and a family approach may produce more effective, long-term benefits for the patient, according to a researcher.
How many opioid painkillers do surgery patients need? New prescribing recommendations unveiled
Mon, 16 Oct 2017 12:45:04 EDT
Surgeons performing 11 common operations can turn to a free new prescribing tool based on data about how many opioid painkillers patients across Michigan actually took after their operations.
Neutrons observe vitamin B6-dependent enzyme activity useful for drug development
Mon, 16 Oct 2017 12:44:40 EDT
Scientists have performed neutron structural analysis of a vitamin B6-dependent protein, potentially opening avenues for new antibiotics and drugs to battle diseases such as drug-resistant tuberculosis, malaria and diabetes. Specifically, the team used neutron crystallography to study the location of hydrogen atoms in aspartate aminotransferase, or AAT, an enzyme vital to the metabolism of certain amino acids.
Whales and dolphins have rich 'human-like' cultures and societies
Mon, 16 Oct 2017 12:22:01 EDT
Whales and dolphins (cetaceans) live in tightly-knit social groups, have complex relationships, talk to each other and even have regional dialects -- much like human societies. A major new study has linked the complexity of Cetacean culture and behavior to the size of their brains.
Gestational diabetes and cardiovascular disease risk
Mon, 16 Oct 2017 12:21:56 EDT
A history of gestational diabetes was associated with a modest higher long-term risk of cardiovascular disease in women in a new study, although the absolute rate of cardiovascular disease was low in the study's younger group of predominantly white women and adhering to a healthy lifestyle over time appeared to help mitigate the risk, according to a new article.
Auto-fix tool gets more programmers to upgrade code, study finds
Mon, 16 Oct 2017 12:21:45 EDT
Failure to make necessary upgrades to software code can have dire consequences, such as the major data breach at Equifax. A recent study finds that auto-fix tools are effective ways to get programmers to make the relevant upgrades -- if programmers opt to use them.
Seeing the light of neutron star collisions
Mon, 16 Oct 2017 12:21:35 EDT
When two neutron stars collided on Aug. 17, a widespread search for electromagnetic radiation from the event led to observations of light from the afterglow of the explosion, finally connecting a gravitational-wave-producing event with conventional astronomy using light, according to an international team of astronomers.
Bite on this: Alligators actually eat sharks
Mon, 16 Oct 2017 12:21:33 EDT
Jaws, beware! Alligators may be coming for you. A new study documents American alligators on the Atlantic and Gulf coasts are eating small sharks and stingrays. This is the first scientific documentation of a widespread interaction between the two predators.
Marketing study examines what types of searches click for car buyers
Mon, 16 Oct 2017 12:21:30 EDT
A new study examines how consumers allocated their time when searching offline and on the internet as they shopped for a new automobile, and what the outcomes were for price satisfaction.

Mon, 16 Oct 2017 12:21:28 EDT
A research team has elucidated the mechanism by which human cells induce inflammation upon detection of cytoplasmic DNA. Notably, the signal network involved differs from that used in the same context in mice.
Childhood poverty, poor support may drive up pregnant woman's biological age
Mon, 16 Oct 2017 12:21:22 EDT
Pregnant women who had low socioeconomic status during childhood and who have poor family social support appear to prematurely age on a cellular level, potentially raising the risk for complications, a new study has found.
