Detecting Long-Term Concussion In Athletes
Lawyers representing both sides in concussion lawsuits against sports leagues may eventually have a new tool at their disposal: a diagnostic signature that uses artificial intelligence to detect brain trauma years after it has occurred.
While the short-term effects of head trauma can be devastating, the long-term effects can be equally hard for patients. The symptoms may linger years after the concussion happened. The problem is it is often hard to say whether their symptoms are being caused by a concussion or other factors like another neurological condition or the normal aging process.
The only way to prove the presence of brain damage caused by concussion years after it occurred was through post-mortem examination. A means of diagnosing concussion in living patients, however, remained elusive.

Preventing Severe Blood Loss On The Battlefield Or In The Clinic
In a tiny room in the sub-basement of Massachusetts Institute of Technology (MIT’s) Building 66 sits a customized, super-resolution microscope that makes it possible to see nanoscale features of a red blood cell. Here, Reginald Avery, a fifth-year graduate student in the Department of Biological Engineering, can be found conducting research with quiet discipline, occasionally fidgeting with his silver watch.
He spends most of his days either at the microscope, taking high-resolution images of blood clots forming over time, or at the computer, reading literature about super-resolution microscopy. Without windows to approximate the time of day, Avery’s watch comes in handy. Not surprisingly for those who know him, it’s set to military time.
Avery describes his father as a hard-working inspector general for the US Army Test and Evaluation Command. Avery and his fraternal twin brother, Jef

Diet Rich In Tomatoes Cuts Skin Cancer In Half In Mice
Daily tomato consumption appeared to cut the development of skin cancer tumors by half in a mouse study at The Ohio State University.
The new study of how nutritional interventions can alter the risk for skin cancers appeared online in the journal Scientific Reports.
It found that male mice fed a diet of 10% tomato powder daily for 35 weeks, then exposed to ultraviolet light, experienced, on average, a 50% decrease in skin cancer tumors compared to mice that ate no dehydrated tomato.
The theory behind the relationship between tomatoes and cancer is that dietary carotenoids, the pigmenting compounds that give tomatoes their color, may protect skin against UV light damage, said Jessica Cooperstone, co-author of the study and a research scientist in the Department of Food Science and Technology in the College of Food, Agricultural, and Environmental Sciences at Ohio State.

ADHD Medication Tied To Lower Risk For Alcohol, Drug Abuse In Teens And Adults
The use of medication to treat attention deficient hyperactivity disorder is linked to significantly lower risk for substance use problems in adolescents and adults with ADHD, according to a study led by researchers at Indiana University.
The risk of substance use problems during periods of medication use was 35% lower in men and 31% lower in women in the study. The results, based upon nearly 3 million people with ADHD in the United States, are reported in the American Journal of Psychiatry.
"This study contributes to growing evidence that ADHD medication is linked to lower risk for many types of harmful behavior, including substance abuse," said Patrick D. Quinn, a postdoctoral researcher in the IU Bloomington College of Arts and Sciences' Department of Psychological and Brain Sciences, who led the study. "The results also highlight the importance of careful diagnosis and compliance w
