Profs’ research dissects science of uncertainty

February 10, 2012 Comments are Disabled

You are standing in line at Mama Kim’s — your mind is racing and your mouth is salivating. Two weeks ago, you had the beef bulgogi rice set, and it was delicious. But tonight you are torn. Do you go with the bulgogi again because you know how much you like it, or do you try the beef galbi and potentially find an even better culinary delight? Should you exploit known rewards or explore, hoping to reap an even better prize? 

Melanoma study raises red flag

February 3, 2012 Comments are Disabled

Dermatologists have long promoted the ABCDs of melanoma detection­ — A for asymmetry, B for border irregularity, C for color variation and D for diameter larger than six millimeters. But a recent study on nodular melanoma — an aggressive subtype of the skin cancer — forced Martin Weinstock, professor of dermatology and epidemiology, to suggest a few more letters for the alphabet.

Grad unveils dinosaur wings

As an undergraduate at the University of California at Berkeley, Ryan Carney, a PhD candidate, was the lead singer and songwriter for his  own punk rock band, said Kevin Padian, Carney’s undergraduate thesis advisor and professor of integrative biology at Berkeley. As a Brown graduate student, Carney has not left his rock days behind. Now he applies his creativity to a different kind of rock — the rock that contains fossils of the archaeopteryx, a 150-million-year-old winged dinosaur that has fascinated Carney ever since he watched a TV program about it as a young boy.

A high-fat diet may not always pack on the pounds, new research from the Warren Alpert Medical School suggests. By successfully preventing weight gain in mice, researchers have shed light on obesity prevention in humans.

Flash heat rocks earthquake physics

October 13, 2011 Comments are Disabled

Rather than turning to broad-scale plate tectonics to investigate earthquakes, David Goldsby, associate professor of geological sciences, and Terry Tullis, professor emeritus of geological sciences, decided to take a closer look. Their study, published in this week’s issue of the journal Science, examines earthquake processes on a microscopic scale.
