No one expects the machinery of progress to roll backwards, but sometimes it seems that no one is watching the speedometer (or manning the brakes, assuming any exist).  Is this a fair assessment? If so, should we be worried — and what can we do about it?

In this feature, experts on technology, risk, science, policy and neuroscience discuss risk, innovation and how our values affect our conceptions of both.

Researchers have finished the first full genome map of the threatened Mojave desert tortoise (Gopherus agassizii), also known as Agassiz’s desert tortoise.

They hope their findings will inform conservation efforts, improve understanding of its evolutionary past and potentially contribute  to  human medicine.

Zoo Conservation Center Pulls Native Species Back from the Brink

As Congress eases rules for selling public lands and considers measures to weaken the Endangered Species Act, conservation efforts may rely increasingly on private facilities like the Phoenix Zoo, which supports its Arthur L. and Elaine V. Johnson Foundation Native Species Conservation Center with a portion of its gate receipts.
