Remember those frog transparencies from biology class? The ones in the textbook where you could lay the circulatory system on top of the digestive system on top of the skeleton system? Here's that same idea, updated and gently presented for kids, from a company called Tinybop. This time, the layers are cut from colored paper, exquisitely designed by Kelli Anderson. And this time (unlike that sadly frozen frog) it moves! Watch it eat a pizza slice ...
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.
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.
From NPR News, this is ALL THINGS CONSIDERED. I'm Audie Cornish.
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.
Ebola, your days as one of the world's scariest diseases may be numbered.
A team of U.S. government researchers has shown that deadly Ebola hemorrhagic fever can be vanquished in monkeys by an experimental drug given up to five days after infection — even when symptoms have already developed.
An antibody cocktail aimed at Ebola's outer surface rescued three of seven macaques infected with lethal doses of the hemorrhagic virus in the U.S. Army's high-security labs at Fort Detrick, Md.
Biologist Bernd Heinrich was in Zimbabwe, in the field, eyes down, looking for beetles, when for no particular reason he looked up and saw ... well, at first he wasn't sure what it was, so he stepped closer, leaned in, and there, painted on the underside of large protruding rock, were five human figures "running in one direction, from left to right across the rock face." They weren't very detailed, just "small, sticklike human figures in clear running stride" painted by a Bushman, two, maybe three thousand years ago.
