UA Study Examines How News Spreads on Twitter

A study of the Twitter activity of 12 major news agencies shows varying levels of success for the social network as a news-sharing tool, based on factors like article lifespan and number of retweets

Nearly every major news organization has a Twitter account these days, but just how effective is the microblogging website at spreading news?

Football Scores a Health Hat Trick for Hypertensive Men

Playing football (soccer) could be the best way for people with high blood pressure, known as hypertension, to improve their fitness, normalise their blood pressure and reduce their risk of stroke, according to research published today (Monday 15 October 2012) in the journal Medicine and Science in Sports and Exercise.

Research from Universities of Exeter and Copenhagen, and Gentofte University Hospital in Denmark suggests football training prevents cardiovascular disease in middle-aged men with hypertension and is more effective than healthy lifestyle advice currently prescribed by GPs.

After six months of football training, three out of four men in this study had blood pressure within the normal, healthy range. (more…)

Engineered Flies Spill Secret of Seizures

Scientists have observed the neurological mechanism behind temperature-dependent — febrile — seizures by genetically engineering fruit flies to harbor a mutation analogous to one that causes epileptic seizures in people. In addition to contributing the insight on epilepsy, their new study highlights the first use of genetic engineering to swap a human genetic disease mutation into a directly analogous gene in a fly.

PROVIDENCE, R.I. [Brown University] — In a newly reported set of experiments that show the value of a particularly precise but difficult genetic engineering technique, researchers at Brown University and the University of California–Irvine have created a Drosophila fruit fly model of epilepsy to discern the mechanism by which temperature-dependent seizures happen.
