A Chronicle of a Whale's Life, Captured in Earwax

Transcript

JOHN DANKOSKY, HOST:

Now you've probably seen a cutaway section of a tree trunk, those rings inside? Well, they tell a story about the conditions the tree faced year after year. It turns out that whales contain a similar record inside their ears. Joining me now to talk about it are two researchers looking into this record. Stephen Trumble is an assistant professor of biology. Sascha Usenko is an assistant professor of environmental science. They're both at Baylor University in Waco, Texas. Welcome to SCIENCE FRIDAY.

Doing A Da Vinci — If Only Leonardo Could See This

Leonardo da Vinci wikipaintings.org

More than 500 years ago, Leonardo da Vinci tried to imagine what it would be like to soar over mountains, to dip, to glide like a bird. He'd sit on Italian hillsides, sketching, imagining, dreaming. In 1502, he drew one of the first ever, looking-down-from-the-sky panoramas of the Earth — in this case a bit of Tuscany, as if seen by a high flying eagle.

A year after doctors first identified an illness that came to be known as Middle Eastern Respiratory Syndrome researchers are reporting fresh genetic information about the virus that causes it.

The findings don't bring scientists any closer to understanding where MERS is coming from. In fact, the main news is that researchers were wrong about the source of some infections in the largest cluster of cases so far.

EPA Wants To Limit Greenhouse Gases From New Coal Power Plants

The Environmental Protection Agency's second stab at a proposal to set the first-ever limits on greenhouse gas emissions from new power plants would make it impossible for companies to build the kind of coal-fired plants that have been the country's biggest source of electricity for decades.

Under the proposal, released Friday, any new plant that runs on coal would be permitted to emit only about half as much carbon dioxide as an average coal plant puts into the air today.

Beloved Brazilian Monkey Clings To A Shrinking Forest

The wild population of the golden lion tamarin, which lives only in Brazil's Atlantic Forest, fell to just 200 in the 1970s. Conservationists have helped the species rebound, but the monkeys are still at risk as development encroaches on their remaining habitat.

The tiny, copper-hued golden lion tamarin is so beloved in Brazil that its image graces the country's 20-real bank note. But this lion-maned monkey is in peril.

There's only one place on earth where the golden lion tamarin lives in the wild: in Brazil's Atlantic Forest, or Mata Atlantica, just north of Rio de Janeiro. Deforestation in the region has reduced the monkey's habitat, once a massive ecosystem stretching for a half-million square miles, to just 2 percent of its original size.
