New insights into genetic basis of bird migration

A gene newly associated with the migratory patterns of golden-winged and blue-winged warblers could lend insight into the longstanding question of how birds migrate across such long distances.

Hormonal birth control alters scent communication in primates

Hormonal contraceptives change the ways captive ring-tailed lemurs relate to one another both socially and sexually, according to a Duke University study that combined analyses of hormones, genes, scent chemicals and behavior.

Genetic components of political preference

Rose McDermott, professor of political science at Brown University, will discuss the growing field of research that explores possible links between genetics and political preferences at the annual meeting of the American ...

Researchers build a toolbox for synthetic biology

For about a dozen years, synthetic biologists have been working on ways to design genetic circuits to perform novel functions such as manufacturing new drugs, producing fuel or even programming the suicide of cancer cells.

Can Seabiscuit's DNA explain his elite racing ability?

Seabiscuit was not an impressive-looking horse. He was considered quite lazy, preferring to eat and sleep in his stall rather than exercise. He'd been written off by most of the racing industry after losing his first 17 races. ...

A genome may reduce your carbon footprint

With the costs of genome sequencing rapidly decreasing, and with the infrastructure now developed for almost anyone with access to a computer to cheaply store, access, and analyze sequence information, emphasis is increasingly ...

Eco-labeled seafood is not always what it seems

When you buy what looks to be a nice piece of certified sustainable fish at the supermarket, you'd like to think that's exactly what you're getting. Unfortunately, things aren't always what they seem, according to researchers ...

The epigenetics of life at 12,000 feet

Humans inhabit an incredible range of environments across the globe, from arid deserts to frozen tundra, tropical rainforests, and some of the highest peaks on Earth. Indigenous populations that have lived in these extreme ...
