2 dying stars reborn as 1
White dwarfs are dead stars that pack a Sun's-worth of matter into an Earth-sized ball. Astronomers have just discovered an amazing pair of white dwarfs whirling around each other once every 39 minutes. This is the shortest-period pair of white dwarfs now known. Moreover, in a few million years they will collide and merge to create a single star. (2011-04-06)

Breast milk appears to aid white matter microstructural organization in preemies
To the growing list of reasons why mothers should consider breast-feeding infants, add another: Critical white matter structures in the brains of babies who are born so prematurely that they weigh less than 1,500 grams develop more robustly when their mothers breast-feed them, compared with preemie peers who are fed formula. (2017-05-04)

(2013-09-09)

Obesity is in the eye of the beholder
Doctors have a specific definition of what it means to be overweight or obese, but in the social world, gender, race and generation matter a lot for whether people are judged as 'thin enough' or 'too fat.' (2017-05-18)

Alcohol and the brain: Moderation does some good, some harm
How much alcohol an elderly person drinks each week is linked to their brain structure and risk of stroke, for better and for worse, according to a study of more than 3,000 senior citizens, published in the September issue of Stroke: Journal of the American Heart Association. (2001-09-06)

Presumed young star turns out to be a galactic senior citizen
49 Lib, a relatively bright star in the southern sky, is twelve billion years old rather than just 2.3 billion. For many decades, researchers were stumped by conflicting data pertaining to this celestial body, because they had estimated it as much younger than it really is. Determining its age anew, astronomers at Ruhr-Universit├Ąt Bochum have now successfully resolved all inconsistencies. Dr. Klaus Fuhrmann and Professor Dr. Rolf Chini published their results in the Astrophysical Journal. (2017-01-16)

Study links physical activity in older adults to brain white-matter integrity
Like everything else in the body, the white-matter fibers that allow communication between brain regions also decline with age. In a new study, researchers found a strong association between the structural integrity of these white-matter tracts and an older person's level of daily activity -- not just the degree to which he or she engaged in moderate or vigorous exercise, but also whether the person was sedentary the rest of the time. (2014-09-17)

Aerobic exercise may help prevent and perhaps even reverse some of the brain damage associated with heavy alcohol consumption, according to a new University of Colorado Boulder study. (2013-04-16)

Research shows testosterone changes brain structures in female-to-male transsexuals
Brain imaging shows that testosterone therapy given as part of sex reassignment changes the brain structures and the pathway associated with speech and verbal fluency. This result supports research that women in general may deal with speech and interaction differently than men. (2015-08-30)

Physically fit kids have beefier brain white matter than their less-fit peers
A new study of 9- and 10-year-olds finds that those who are more aerobically fit have more fibrous and compact white-matter tracts in the brain than their peers who are less fit. 'White matter' describes the bundles of axons that carry nerve signals from one brain region to another. More compact white matter is associated with faster and more efficient nerve activity. (2014-08-19)

Findings indicate that aerobic exercise benefits the brain's white matter integrity. (2013-04-16)

Slow reading in dyslexia tied to disorganized brain tracts
Researchers at Children's Hospital Boston and Beth Israel Deaconess Medical Center have found that difficulty in reading smoothly, or fluently, which occurs in some types of dyslexia, may be caused by disorganized, meandering tracts of nerve fibers in the brain. The findings, which point to organized white matter as the structural basis in the brain for fluent reading, could help specialists find new ways to improve the automatic nature of reading in individuals with dyslexia. (2007-12-03)
