Of all the creatures in the sea, one of the most majestic and mysterious is the whale shark. It's the biggest shark there is, 30 feet or more in length and weighing in at around 10 tons.
Among the mysteries is where this mighty fish migrates and where it gives birth. Now scientists have completed the biggest study ever of whale sharks, and they think they have some answers to those questions.

Sometimes you have to give up a little privacy in order to find out how much — or how little — privacy you really have. So I handed over the keys to my Gmail account to Cesar Hidalgo, a professor at the MIT Media Lab and the designer of a program called Immersion.
When the drug company Merck Animal Health announced plans to suspend sales of its Zilmax feed additive last week, many observers were shocked.
Yet concern about Zilmax and the class of growth-promotion drugs called beta agonists has been building for some time. In an interesting twist, the decisive pressure on Zilmax did not come from animal welfare groups or government regulators: It emerged from within the beef industry itself, and from academic experts who have long worked as consultants to the industry.
Facebook founder and CEO Mark Zuckerberg has teamed up with other tech giants to pursue the goal of providing Internet service to five billion people in the developing world. The group, called Internet.org, says data can be used more efficiently and participating partners can work cooperatively to make access to the web affordable in emerging economies. Zuckerberg makes the case on his Facebook page for how a global Internet infrastructure can be created. But the document doesn't have tangible commitments from Facebook or other participating companies.

MELISSA BLOCK, HOST:
I'm Melissa Block. And a radio confession here. We had a hole in our program right here. We didn't have a piece just the right length to fill out this segment. It happens occasionally. Well, all summer, NPR science correspondent Joe Palca has been helping us get rid of these little holes with some short stories about holes.
JOE PALCA, BYLINE: Today, we're going to examine the question, what is a hole anyway? What's it made of?

For nearly a year, disease detectives around the world have been trying to track down the source of a mysterious new virus in the Middle East that has infected 96 people and killed 47 since September.
Now it looks like they've pinpointed at least one place where the virus is hiding out.
Scientists at Columbia University have detected the Middle East respiratory syndrome virus, or MERS, in a bat near the home of a man who died from the disease. The team found a small fragment of the virus's genes in the animal that matches perfectly with those seen in the patient.
Rocky, windswept Eastern Egg Rock, about 6 miles off the coast of Maine, was once a haven for a hugely diverse bird population. But in the 1800s, fishermen decimated the birds' ranks — for food and for feathers.
When ornithologist Stephen Kress first visited 40 years ago, the 7-acre island was nearly barren, with only grass and gulls left. Not a puffin in sight. Not even an old puffin bone.

This week's innovation pick is a shower head that reminds you you're taking too long. The Uji shower head gradually turns from green to red as users linger in the shower.
"It encourages [people] to take shorter and more energy efficient showers," said one of the co-inventors, Brett Andler. "By letting people become aware of how long they're in the shower, we've actually been able to cut shower time by 12 percent."
