A McGill-led research team has recently discovered that for girls who are carriers of a particular gene variant (DRD4 VNTR with 7 repeats), the crucial element that influences a child's fat intake is not the gene variant itself. Instead, it is the interplay between the gene and girls' early socioeconomic environment that may determine whether they have increased fat intake or healthier than average eating compared to their peers from the same class background.
Differences in the neural wiring across development of men and women across ages, matched behavioral differences commonly associated with each of the sexes, according to an imaging-based study from researchers at the Perelman School of Medicine at the University of Pennsylvania published Feb. 1 in Philosophical Transactions of the Royal Society B.
A USC-led team of researchers have hope that behavioral interventions could help doctors slow the rise of treatment-resistant infections in hospitals and clinics, reduce adverse drug events in patients, and lower health care costs.
Infant girls at risk for autism pay more attention to social cues in faces than infant boys, according to a Yale School of Medicine study -- the first one known to prospectively examine sex-related social differences in at-risk infants.
A team at Cold Spring Harbor Laboratory has discovered the purpose of a highly conserved genetic tool that is present in both mosses and flowering plants, organisms whose common ancestor dates back 450 million years. As they report in Developmental Cell, the gene network, which comprising a snippet of non-coding genetic material called a small RNA and the protein it regulates, has been used over the eons to make plants more sensitive to environmental cues and facilitate robust, yet flexible, responses to those cues.
In injured mouse intestines, specific types of bacteria step forward to promote healing, Emory scientists have found. Potentially, some of these microbes could be exploited as treatments for conditions such as inflammatory bowel disease.
Researchers from Carnegie Mellon University have created the first robotically driven experimentation system to determine the effects of a large number of drugs on many proteins, reducing the number of necessary experiments by 70 percent.
A new way of mapping the collection of RNA read-outs that are expressed by a cell's active genes has been devised to shed additional light on the role of RNAs in cells. These 'dark' variations in RNA likely have roles in gene regulation across tissues, development, and in human diseases. The team will use the now-free software to interrogate cells in brain disorders, cancers, and other illnesses.
A new study published in the Journal of the American Heart Association found that a diet containing unsaturated fats, such as those found in walnuts and olive oil, has similar weight loss effects as a lower fat, higher-carbohydrate diet.1 The research, led by Dr. Cheryl Rock of the University of California, San Diego School of Medicine, also showed that a diet containing walnuts, which are primarily comprised of polyunsaturated fats, positively impacts heart health markers, such as cholesterol.
Washington State University researchers have determined how a protein that helps cells fight viruses can also cause genetic mutations that lead to cancer.
