To age is primate

To age is primate. Duke Today, March 10, 2011. For a long time scientists thought that humans aged more slowly than other animals, especially given our relatively long life spans and access to modern medicine. But now, the first-ever comparison of human aging patterns with those in chimps and other primates suggests the pace of human aging may not be so unique after all.

Primates are more resilient than other animals to environmental ups and downs. National Evolutionary Synthesis Center, December 1, 2010.What sets mankind’s closest relatives — monkeys, apes, and other primates — apart from other animals? According to a new study, one answer is that primates are less susceptible to seasonal ups and downs. Picked up by TIME Magazine.

Scared snails opt for single parenthood rather than wait for a mate. National Evolutionary Synthesis Center, August 16, 2010. Solitary snails in search of a mate put off parenthood as long as possible in the hopes that a partner will appear. But scared snails settle for single parenthood much sooner than their calm counterparts, says a new study. Picked up by USA Today, the Dallas Morning News, and LiveScience.
