As a lead-up to the forthcoming History Channel series “Vikings,” Tom Ashbrook, host of NPR’s “On Point,” talked with a foremost authority on the subject — Yale’s Anders Winroth — to de-mystify the legendary raiders of the North.

Winroth is professor and director of graduate studies in history. His most recently published book is “The Conversion of Scandinavia: Vikings, Merchants, and Missionaries in the Remaking of Northern Europe” (Yale University Press, 2011). His forthcoming volume, “A New History of the Viking Age,” will be published by Princeton University Press in 2014. YaleNews spoke with Winroth recently about some of the issues raised in his “On Point” interview. The following is an edited transcript. (more…)

EAST LANSING, Mich. — The stock market should be regulated only during times of extraordinary financial disruptions when speculators can destroy healthy businesses, according to a new study led by a Michigan State University scholar.

The answer: rarely. The SEC should step in only when outside financial disruptions make it impossible for large shareholders to fend off “short sellers” – or speculators betting a company’s stock value will decrease, said Naveen Khanna, finance professor in MSU’s Broad College of Business. (more…)

Battles of sexes shown to spur adaptive sex differences

Sex differences account for some of the most of the spectacular traits in nature: the wild colours of male guppies, the plumage of peacocks, tusks on walruses and antlers on moose. Sexual conflict – the battle between males and females over mating – is thought to be a particularly potent force in driving the evolution of traits that differ in males and females.

However, the genetic processes responsible for producing such traits are not well understood, nor how they evolved from their simpler less elaborate ancestral forms. We tend to assume that each tiny step in evolution is an advantage. But are they really? (more…)
