Theoretical physicist David Kaplan discusses Particle Fever and the Higgs Boson

submitted by: nsf

Particle Fever, a documentary film about the Large Hadron Collider (LHC) and the Higgs boson, has caught the attention of scientists and non-scientists alike. This interview with David Kaplan, a Johns Hopkins University physics professor and the film's producer, provides a little behind-the-scenes look at life as a physicist and some decision making involved in making Particle Fever.

Lemur lovers' synced scents reflect strength of their bond

submitted by: nsf
Lemur lovers spread their scents by rubbing glands on everything from tree trunks to their partner. Researchers discovered that the more similar a lemur couples' scents, the stronger their bond. This could be a way to coordinate marking territories, or to display their relationship status to the rest of the group. Lemurs are an endangered species, so learning about mating techniques could be essential to their preservation. For more information visit...

Walt Wilczynski discusses research on the responses by non-mammals to signals during mating competitions

submitted by: nsf

Walter Wilczynski of Georgia State University is researching how non-mammals signal one another in mating competitions, and how these signals influence the behavior of individual males and females. According to Wilczynski's research, an individual's behavioral responses to such signals and whether it loses or wins a mating competition may modify its brain in ways that may influence its future behavior.
