A new analysis based on an Apollo scientist’s copies of lost NASA data seeks to determine how sticky, abrasive moon dust will affect lengthier future lunar missions.
The author of the new study, Brian O’Brien, was the principal investigator for the dust detectors left behind in 1969 by the first two manned missions to the Moon, Apollo 11 and Apollo 12. At the time, O’Brien was a professor of space science at Rice University in Houston, Texas. Continue reading Apollo scientist dusts off ‘lost’ lunar data→
In September 2008, Forbes science editor Matthew Herper and former Washington Post reporter Rick Weiss appeared together on a panel at the World Stem Cell Summit in Madison, Wisconsin. In late February, Herper received an invitation to ‘friend’ Weiss on the Internet social-networking site Facebook. On the basis of their acquaintance, Herper accepted, noticing that a number of other people involved with stem cells were listed as friends on Weiss’s profile. However, that profile — and many of those it was linked to — was a fake. Continue reading Fake Facebook pages spin web of deceit→
African-American school students asked to write about their personal values for fifteen minutes at the start of the school year earn higher grades for up to two years afterwards.

The findings could suggest that women are a safer pair of hands on the stock-market trading floor than men — or throw into doubt earlier findings about the effect of the hormone on men.
