Des chercheurs décomposent les substances toxiques de la nature pour découvrir comment leurs molécules fonctionnent. Leur travail ouvre notamment la voie à la fabrication d’analgésiques d’un genre nouveau.

Coulson, who was a graduate student with Staples and Guglielmo at the time, led a study on the yellow-rumped warbler, a songbird that migrates between Canada, where it nests, and its wintering grounds in the United States, Mexico and the Caribbean. First, during the birds’ fall migration, they captured the southbound songbirds and brought them into the lab. There, they managed the birds’ exposure to light and darkness to create two laboratory groups of “migratory” and “nonmigratory” warblers.

By Elizabeth Landau, Senior Communications Specialist, NASASince the big bang, the early universe had hydrogen, helium, and a scant amount of lithium. Later, some heavier elements, including iron, were forged in stars. But one of the biggest mysteries in astrophysics is: How did the first elements heavier than iron, such as gold, get created and distributed throughout the universe?

During Panama’s wet season, forests boom with a chorus of túngara frog mating calls as males compete for females’ attention.But these calls put the frogs in a precarious position between sex and death. For a fringe-lipped bat, it’s as though its meal is ringing a dinner bell. Bats navigate the world with echolocation, listening to the sound waves of their own calls bouncing off nearby objects. Their hearing is so precise they can even home in on prey using ripples that frog calls make on water.

Since the big bang, the early universe had hydrogen, helium, and a scant amount of lithium. Later, some heavier elements, including iron, were forged in stars. But one of the biggest mysteries in astrophysics is: How did the first elements heavier than iron, such as gold, get created and distributed throughout the universe? “It’s a pretty fundamental question in terms of the origin of complex matter in the universe,” said Anirudh Patel, a doctoral student at Columbia University in New York.
