Study Links Physical Activity to Greater Mental Flexibility in Older Adults
CHAMPAIGN, Ill. -- One day soon, doctors may determine how physically active you are simply by imaging your brain. Physically fit people tend to have larger brain volumes and more intact white matter than their less-fit peers. Now a new study reveals that older adults who regularly engage in moderate to vigorous physical activity have more variable brain activity at rest than those who don't. This variability is associated with better cognitive performance, researchers say.

The Nonagenarian Athlete: Researchers Study Olga Kotelko's Brain
CHAMPAIGN, Ill. -- In the summer of 2012, Olga Kotelko, a 93-year-old Canadian track-and-field athlete with more than 30 world records in her age group, visited the Beckman Institute for Advanced Science and Technology at the University of Illinois and submitted to an in-depth analysis of her brain. The resulting study, reported in the journal Neurocase, offers a surprising first glimpse of the potential effects of exercise on the brains and cognitive abilities of the "oldest old."

Rogue Supernovas Likely Flung into Space by Black Hole Slingshots
CHAMPAIGN, Ill. - Rogue supernovas that explode all alone in deep space present an astronomical mystery. Where did they come from? How did they get there? The likely answer: a binary black hole slingshot, according to a new study by Ryan Foley, a professor of astronomy and physics at the University of Illinois.

Study Links Cardiorespiratory Fitness, Thinner Gray Matter And Better Math Skills in Kids
CHAMPAIGN, Ill. -- A new study reveals that 9- and 10-year-old children who are aerobically fit tend to have significantly thinner gray matter than their "low-fit" peers. Thinning of the outermost layer of brain cells in the cerebrum is associated with better mathematics performance, researchers report in the journal PLOS ONE.

Study: Sequential Voting in Presidential Primaries Best System to Winnow Candidates
HAMPAIGN, Ill. -- As the race for the 2016 Democratic and Republican presidential nominations enters the early stages, voters have a large pool of candidates to consider, including 17 declared candidates on the Republican side alone.

Simple Intervention Can Moderate Anti-vaccination Beliefs, Study Finds
CHAMPAIGN, Ill. -- It might not be possible to convince someone who believes that vaccines cause autism that they don't. Telling skeptics that their belief is not scientifically supported often backfires - strengthening, rather than weakening, their anti-vaccine views. But researchers say they have found a way to overcome some of the most entrenched anti-vaccine attitudes: Remind the skeptics, with words and images, why vaccines exist.

Parents' Health Literacy Affects Child Weight-loss Tactics, Study Finds
CHAMPAIGN, Ill. -- Parents who have low health literacy are less likely to choose government-recommended weight-loss strategies, such as increasing physical activity or serving more fruits and vegetables, to help their children control their weight than parents who are better able to understand basic health-related information, a new study suggests.

Chill-tolerant Hybrid Sugarcane Also Grows at Lower Temperatures, Team Finds
CHAMPAIGN, Ill. -- U.S. farmers have long hoped to extend sugarcane's growing range northward from the Gulf coast, substantially increasing the land available for sugar and biofuels. Several hybrid canes developed in the 1980s have proved hardy in cooler climes, surviving overwinter as far north as Booneville, Arkansas. But until now, no one had tested whether these "miscanes," as they are called, actually photosynthesize, and thus continue to grow, when the thermometer dips.
