Piecing together the events of the farthest touchdown a manmade spacecraft has ever made on an alien world reveals new clues about Titan’s surface and helps plan future missions to moons and planets.

The Huygens probe, ferried to Saturn’s moon Titan by NASA’s Cassini spacecraft, bounced, slid and wobbled its way to rest in the 10 seconds after touching down on Titan in January 2005, a new analysis reveals. The moon’s surface is more complex than previously thought.

Scientists reconstructed the chain of events by analyzing data from a variety of instruments that were active during the impact, in particular changes in the acceleration experienced by the probe. The probe was supplied by the European Space Agency and named after the Dutch 17th century astronomer Christiaan Huygens. (more…)

*UD professor’s book examines ‘Black Politics Today’*

The civil rights legislation of the 1960s, which sought to empower and strengthen the black community, now indirectly poses a threat to the group’s collective social, political and economic development, according to Theodore Davis, University of Delaware associate professor.

His new book, Black Politics Today, suggests that the rise of a new black middle class—one that is wealthier, better educated and not faced with the same limitations and restraints of their pre-civil rights predecessors—has created a rift in shared aspirations, social bonds and values within the black community.

Davos, Switzerland — Jan. 30, 2012 — When the world’s policymakers descend on Davos, Switzerland, for the World Economic Forum Annual Meeting, Bill Gates can usually get their attention.

This year, in between discussing food sustainability and announcing a US$750 million donation to fight AIDS, malaria, and tuberculosis, Gates turned his attention to a few students who hope to make a similarly outsized humanitarian mark on the world. (more…)

A ground-breaking innovation, birthed in a sudden flash of insight, is the stuff of legend. Air conditioning, Kevlar, the DNA-replicating process known as PCR (polymerase chain reaction) — each was the product of a Eureka! moment. The list may soon be longer by one, thanks to a wandering mind and a napkin.

When Jud Ready attended an academic conference on materials science in Boston in 2003, he didn’t plan on coming home with the idea for a three-dimensional solar cell, but that’s what happened. (more…)
