Stable isotope analysis of hair from bonobos shows that the diet of these great apes may vary with social rank and reproductive status, according a study published Sept. 14, 2016 in the open-access journal PLOS ONE by Vicky Oelze from Max Planck Institute for Evolutionary Anthropology, Germany, and colleagues.
Scientists at Baylor College of Medicine, the National Institutes of Health and Virginia Tech Carilion Research Institute have discovered a new mechanism in the mouse brain that regulates obesity. The study, which appears in Cell Reports today, shows that this new mechanism can potentially be targeted to treat obesity.
A Johns Hopkins University researcher noticed the bats he works with cocked their heads to the side, just like his pet pug. As the article publishing in open-access journal PLOS Biology details, using high-tech recording devices, Wohlgemuth determined that a bat's fetching head waggles and ear wiggles sync with the animal's sonar vocalizations to help it hunt. The finding demonstrates how movement in bats can enhance signals used by senses like sight and hearing.
Why do we -- and the fruit flies that sometimes inhabit our kitchens -- seek out protein-full foods when we're running on empty? And what does that preference mean for the odds of living a longer life, whether it's measured in decades for a human, or days for a fly? New research suggests that a brain chemical may have a lot to do with both questions.
Three out of four (75 percent) people in the UK are unaware of the link between obesity and cancer, according to a new Cancer Research UK report published today.
Today's industrial yeast strains are used to make beer, wine, bread, biofuels, and more, but their evolutionary history is not well studied. In a Cell paper publishing Sept. 8, researchers describe a family tree of these microbes with an emphasis on beer yeast. The resulting genetic relationships reveal clues as to when yeast was first domesticated, who the earliest beer brewers were, and how humans have shaped this organism's development.
A study published in PLOS Neglected Tropical Diseases suggests that the health and economic burden of hookworm infection is estimated to exceed those of a number of diseases receiving greater attention and investment. Sarah Bartsch from John Hopkins Bloomberg School of Public Health, Peter Hotez from Baylor College of Medicine, and colleagues found that human hookworm infection confers a substantial global health and economic burden through loss of productivity, and years of life living with disability due to infection outcomes.
According to a new study, turning lawn into a vegetable garden can reduce greenhouse gas emissions.
For many people, there's nothing more satisfying than a hot, spicy meal. But some research has suggested that capsaicin, the compound that gives chili peppers their kick, might cause cancer. Now researchers show in mouse studies that the pungent compound in ginger, 6-ginergol, could counteract capsaicin's potentially harmful effects. In combination with the capsaicin, 6-gingerol could lower the risk of cancer, they say. The study appears in ACS' Journal of Agricultural and Food Chemistry.
Research published in the Journal of Nutrition has for the first time, documented the potential effects of mango consumption on gut microbiota of mice. When samples were compared from the beginning to the end of the study period, mango supplementation was found to prevent the loss of beneficial gut bacteria often induced by a high-fat diet. This is an important finding as specific bacteria in the intestinal tract may play a role in obesity and obesity-related complications, such as type 2 diabetes.
