NASA's STEREO detects a CME from the sun
On 5:24 a.m. EDT on May 17, 2013, the sun erupted with an Earth-directed coronal mass ejection or CME, a solar phenomenon that can send billions of tons of solar particles into space that can reach Earth one to three days later and affect electronic systems in satellites and on the ground. Experimental NASA research models, based on observations from NASA's Solar Terrestrial Relations Observatory, show that the CME left the sun at speeds of around 745 miles per second. The solar material in CMEs cannot pass through the atmosphere to affect humans on Earth.

New study pinpoints biochemical mechanism underlying fibrosis following glaucoma surgery
The most common cause of failure after glaucoma surgery is scarring at the surgical site, so researchers are actively looking for ways to minimize or prevent scar formation. Previous work had suggested that vascular endothelial growth factor (VEGF) activates fibrosis, whereas VEGF inhibition results in reduced scar formation and better surgical results. In a series of studies using a rabbit model of glaucoma surgery, investigators have determined that VEGF probably exerts its effects through induction of transforming growth factor (TGF)-β1, which may open up a new target for therapies to improve glaucoma surgical outcomes. This study is published in the June 2013 issue of The American Journal of Pathology.

Individuals who drink heavily and smoke may show 'early aging' of the brain
Treatment for alcohol use disorders works best if the patient actively understands and incorporates the interventions provided in the clinic. Multiple factors can influence both the type and degree of neurocognitive abnormalities found during early abstinence, including chronic cigarette smoking and increasing age. A new study is the first to look at the interactive effects of smoking status and age on neurocognition in treatment-seeking alcohol dependent (AD) individuals. Findings show that AD individuals who currently smoke show more problems with memory, ability to think quickly and efficiently, and problem-solving skills than those who don't smoke, effects which seem to become exacerbated with age.

College women exceed NIAAA drinking guidelines more frequently than college men
In order to avoid harms associated with alcohol consumption, in 2009 the National Institute on Alcohol Abuse and Alcoholism issued guidelines that define low-risk drinking. These guidelines differ for men and women: no more than four drinks per day, and 14 drinks per week for men, and no more than three drinks per day, and seven drinks per week for women. A study of how well college students adhere to these limits has found that female college student drinkers exceed national drinking guidelines for weekly drinking more frequently than their male counterparts.
Youth who have their first drink during puberty have higher levels of later drinking
Research shows that the earlier the age at which youth take their first alcoholic drink, the greater the risk of developing alcohol problems. Thus, age at first drink (AFD) is generally considered a powerful predictor of progression to alcohol-related harm. A new study shows that individuals who have their first drink during puberty subsequently have higher drinking levels than do individuals with a post-pubertal drinking onset.

What is being offered is a headband and mobile app designed to help the person measure concentration and understand the person's focus highs and lows and try to improve.
Temporal processing in the olfactory system
The neural machinery underlying our olfactory sense continues to be an enigma for neuroscience. A recent review in Neuron seeks to expand traditional ideas about how neurons in the olfactory bulb might encode information about odorants. One of the main authors, Terry Sejnowski, had the floor for a brief while at last week's national BRAIN Initiative meeting, where discussion of neural codes was a key issue. The Neuron review was published the day after the meeting, and it supports the previously established idea that the olfactory bulb is in many ways structurally comparable to the retina. The authors note however, that due to the apparent sparsity and lack of topographical organization in the olfactory front end, the particular blend of temporal coding used there should differ significantly from that used in the retina.

Coral reef fishes prove invaluable in the study of evolutionary ecology
After reviewing recent research based on the study of habitat-specialist coral reef fishes, Boston University post-doctoral researcher Marian Y. L. Wong and Peter M. Buston, assistant professor of biology, have found that these species have proven invaluable for experimental testing of key concepts in social evolution, noting that studies of these fishes already have yielded insights about the ultimate reasons for female reproductive suppression, group living, and bidirectional sex change. Based on this impressive track record, the researchers maintain that these fishes should be the focus of future tests of key concepts in evolutionary ecology. Their findings are published in an article titled "Social Systems in Habitat-Specialist Reef Fishes: Key Concepts in Evolutionary Ecology" in the June 2013 issue of the journal BioScience.
