Focusing on this species of fruit fly, he and the other researchers in the lab of molecular biologist Sean B. Carroll, had made a prolonged assault on one of the key questions in evolutionary biology: how nature endows creatures with their colorful patterns, from a leopard's dark spots to a butterfly's bold swirls. In different species the patterns serve to attract mates, provide camouflage or provide other advantages in the struggle to survive. But what causes the colors to fall so precisely into place?

While surveying the seafloor last fall, a research vessel spotted bubbles rising from the depths. Now, another ship has gone back to investigate, and found a variety of life on the seafloor surrounding a methane seep, according to an update from researchers with the National Oceanic and Atmospheric Administration (NOAA).

One of these days, there could well be a simple blood test that can help diagnose and track cancers. We aren't there yet, but a burst of research in this area shows we are getting a lot closer.

The hollow Cola tree growing in a remote area of southeastern Guinea was once home to thousands of bats routinely hunted and killed by the neighborhood children. It was also a popular spot to play. A year ago, one child in particular lived within fifty meters of the tree: a two-year-old boy who died in December 2013 and later was identified as the first person in west Africa known to have developed Ebola.

We all know Sally: She is our daughter, our sister, our friend -- her health in the balance. In that moment, we're all looking for a solution, some hope. This 60-second spot begins and ends in Sally's hospital room. It takes us back in time to see the many people who contributed to the discovery, development, and approval of lifesaving medicine.

But then on Dec. 22, 1938, Marjorie Courtenay-Latimer came across a strange blue fin poking out of a pile of fish that struck her as extraordinary. With its fleshy, lobed fins and its tough armored scales, the specimen looked very unlike fish we see in our oceans today. That is because the coelacanth has managed to survive in roughly its current form for hundreds of millions of years. In the course of researching this film, we learned all kinds of amazing facts about the coelacanth. For instance, unlike most fish, they give birth to live young. They produce eggs the size of grapefruits, which then hatch internally. From video footage taken by the explorer Hans Fricke - which we used as inspiration for our sets and puppets - we know coelacanths are prone to some odd behavior. They've been spotted doing headstands underwater.

Whether it's shunning all grains and dairy on a paleo diet, or bingeing on fruit juice to cure your cancer, "fad diets" push some misleading ideas about healthy eating. But knowing some red flags that are common signs of dodgy diets can help you avoid getting sucked in.
