A new paper has linked unhealthy weight control behavior, like vomiting and diet pills, to indoor tanning among high school students.

Another supposed problem for middle class white girls? Not so, say the authors in the Journal of Developmental&Behavioral Pediatrics, the association is even stronger for males.

Stephen M. Amrock, SM, and Michael Weitzman, MD, of the New York University School of Medicine say that indoor tanning might identify a group of teens at increased risk of eating disorders.

A UNIVERSITY of Huddersfield criminologist who has been working closely with authorities in London to cut crime on one of the world's busiest transport systems will appear before a House of Commons select committee to describe his findings. Dr Andrew Newton is also forming links with overseas experts so that their research can make public transport systems around the world safer places to travel.

By analysing crime patterns on the London Underground, which carries more than one billion passengers a year, Dr Newton is able to draw conclusions about the environment of stations and how they can help or hinder crime, such as pickpocketing. There are also important lessons to be learned about the policing of the Tube system and the areas that surround stations.

SAN DIEGO — Given omega 6 fatty acid's reputation for promoting cancer — at least in animal studies — researchers are examining the role that antioxidants play in blocking the harmful effects of this culprit, found in many cooking oils. After all, antioxidants are supposed to prevent DNA damage. But employing antioxidants could backfire, say researchers at Georgetown Lombardi Comprehensive Cancer Center.

In their study, being reported at the AACR Annual Meeting 2015, researchers found that vitamin E actually increased specific damage linked to omega 6 fatty acids. The vitamin promoted the formation of an "adduct," a structure that links a chemical to DNA, and which may cause mutations.

Right now a doomed gas cloud is edging ever closer to the supermassive black hole at the center of our Milky Way galaxy. These black holes feed on gas and dust all the time, but astronomers rarely get to see mealtime in action.

Northwestern University's Daryl Haggard has been closely watching the little cloud, called G2, and the black hole, called Sgr A*, as part of a study that should eventually help solve one of the outstanding questions surrounding black holes: How exactly do they achieve such supermassive proportions?

Las Vegas - A study published recently in PLOS ONE authored by Dr. Henry Sun and his postdoctoral student Dr. Gaosen Zhang of Nevada based research institute DRI provides new evidence that Earth bacteria can do something that is quite unusual. Despite the fact that these bacteria are made of left-handed (L) amino acids, they are able to grow on right-handed (D) amino acids. This DRI study, funded by the NASA Astrobiology Institute and the NASA Exobiology Program, takes a closer look at what these implications mean for studying organisms on Earth and beyond.

In a new paper, researchers writing in Current Biology show how lactase persistence variants tell the story about the ancestry of the Khoe people in southern Africa and that their pastoralist practices were probably brought to southern Africa by a small group of migrants from eastern Africa.
