Intermittent fasting, and fasting in general, has been a popular fad health gimmick, but the science isn't on its side. Instead, proponents believe mice are little people so if mice weaned on starvation diets lived longer, people would also.
New research from the University of Chicago investigates what happens to men's and women's sexual function and relationships after a heart attack in an effort to help clinicians develop better care guidelines for patients. The study, published in JAMA Cardiology, shows impaired sexual function or new problems are common after heart attacks. They occur at the same rate as a loss of general physical function and at a higher rate than the incidence of depression after heart attack, but rarely do health care providers address these issues - particularly with women.
Human occupation is usually associated with deteriorated landscapes, but new research shows that 13,000 years of repeated occupation by British Columbia's coastal First Nations has had the opposite effect, enhancing temperate rainforest productivity.
Andrew Trant, a professor in the Faculty of Environment at the University of Waterloo, led the study in partnership with the University of Victoria and the Hakai Institute. The research combined remote-sensed, ecological and archaeological data from coastal sites where First Nations' have lived for millennia. It shows trees growing at former habitation sites are taller, wider and healthier than those in the surrounding forest. This finding is, in large part, due to shell middens and fire.
ITHACA, NY-- Tomatoes are already an ideal model species for plant research, but scientists at the Boyce Thompson Institute (BTI) just made them even more useful by cutting the time required to modify their genes by six weeks.
Rome, Italy 30 August 2016: New generation drug eluting stents (new DES) did not outshine contemporary bare metal stents (BMS) as they were expected to, in a surprise finding of the largest randomized stent trial to date.
The Norwegian Coronary Stent Trial (NorStent), presented at ESC Congress 2016, and published simultaneously in the New England Journal of Medicine, "demonstrates that the efficacy of new DES versus contemporary BMS is lower than expected," noted Kaare Harald Bonaa, MD, PhD, in a Hot Line session here.
"Patients treated with DES do not live longer and they do not live better than patients treated with BMS."
Though the Affordable Health Care was passed and signed without really knowing what it was, a few things were certain; you could keep your doctor, it would be cheaper due to competition for new customers, and socio-economic disparities would be eliminated.
Female plastic surgeons need more equitable representation in leadership roles, according to an op-ed in Plastic and Reconstructive Surgery.
"Women bring unique qualities to leadership, yet there remain barriers to gender equality," according to the article by five leading women plastic surgeons. "Our failure to attract, nurture, and sustain women for leadership positions significantly reduces the talent pool of capable leaders in plastic surgery," writes Debra J. Johnson, MD, of The Plastic Surgery Center in Sacramento and colleagues.
INDIANAPOLIS - If you really want a drink right now, the source of your craving may be a pea-sized structure deep inside the right side of your brain, according to scientists at the Indiana University School of Medicine.
Using two different kinds of advanced brain imaging techniques (PET and fMRI), the researchers compared the results of giving beer drinkers a taste of their favorite beer versus a sports drink. After tasting the beer the participants reported increased desire to drink beer, whereas the sports drink did not provoke as much desire for beer. The brain scans also showed that the beer flavor induced more activity in both frontal lobes and in the right ventral striatum of the subjects' brains than did the sports drink.
From natural ecosystems to farmers' fields, plants face a dilemma of energy use: outgrow and outcompete their neighbors for light, or defend themselves against insects and disease.
But what if you could grow a plant that does both at the same time?
A team of researchers at Michigan State University is the first to accomplish that feat, and the breakthrough could have fruitful implications for farmers trying to increase crop yields and feed the planet's growing population.

The first study to investigate how dog brains process speech shows that our best friends in the animal kingdom care about both what we say and how we say it. Dogs, like people, use the left hemisphere to process words, a right hemisphere brain region to process intonation, and praising activates dog's reward center only when both words and intonation match, according to a study in Science.
It is now possible for machines to learn how natural or artificial systems work by simply observing them, without being told what to look for, according to researchers at the University of Sheffield.
This could mean advances in the world of technology with machines able to predict, among other things, human behaviour.
The discovery takes inspiration from the work of pioneering computer scientist Alan Turing, who proposed a test, which a machine could pass if it behaved indistinguishably from a human. In this test, an interrogator exchanges messages with two players in a different room: one human, the other a machine.
Do anti-vaccine people hang around with anti-vaccine people or did hanging around with them cause them to lose faith in science?
There are an alarming number of factors that all correlate with anti-vaccine sentiment; the types of food purchased, beliefs about science, beliefs about energy, and beliefs about politics. But did all of those happen, and the people who embraced them gravitated toward each other, or did the social circle create the issue?
Irvine, Calif., Aug. 29, 2016 - As a multiyear drought grinds on in the Southwestern United States, many wonder about the impact of global climate change on more frequent and longer dry spells. As humans emit more carbon dioxide into the atmosphere, how will water supply for people, farms, and forests be affected?
A new study from the University of California, Irvine and the University of Washington shows that water conserved by plants under high CO2 conditions compensates for much of the effect of warmer temperatures, retaining more water on land than predicted in commonly used drought assessments.
