It has taken nearly a decade and 3 billion miles to get there, but scientists are about to get their first look at Pluto.

The New Horizons spacecraft is closing fast on the tiny world once thought to be at the edge of our solar system. On Tuesday the probe will begin an intensive nine-day scientific study of Pluto and its moons.

It has been called the "Super Bowl of the ocean."

Shark Week is a ratings bonanza for the Discovery Channel with more than 40 million people tuning in last year. Shark Week kicked off this weekend with the most hours of programming ever in its 28-year history But many scientists think the huge audiences — and the hype — have come at the expense of real science.

A generation of shark scientists cut their teeth on Shark Week.

The International Space Station has just received a much-needed delivery, including some groceries, aboard a Russian capsule that successfully docked after three previous attempts to resupply the orbiting laboratory had failed.

Those who spend much time on the Carolina beaches know that many shark species, and even whales, are frequent visitors during the summer. And, though it's extremely rare, those sharks have been known to attack humans.

But this year, there have already been seven shark attacks off the North Carolina coast since June. It's a number that has surprised even the most seasoned of shark-watchers.

In catacombs south of Cairo, researchers have discovered burial sites filled with huge numbers of mummified animals — nearly 8 million of them, mostly dogs.

What do we know about the power of food to rev up sex drive? Not much.

"Really, science has not figured out what determines sexual motivation and sexual attraction. If we knew the answer to that, we'd probably be richer than Pfizer after they invented Viagra," says Dolores Lamb, director of the Center for Reproductive Medicine at Baylor College of Medicine.

She hasn't seen any compelling evidence that any particular food can intensify desire.

A sun-powered airplane has landed in Hawaii after a five-day journey from Japan that smashed the previous record of 76 hours for the longest duration nonstop solo flight.

Pilot André Borschberg set the Solar Impulse 2 down on the tarmac at Kalaeloa Airport outside Honolulu after flying for 120 hours from Nagoya, his team reports.

A Russian rocket filled with much-needed supplies for the International Space Station lifted off from a pad in Kazakhstan early today after two previous re-supply missions failed.

NPR's Corey Flintoff reports that the successful launch of the Russian Soyuz spacecraft, known as the Progress 60P, which is set to dock with the station on Sunday, was a relief to the astronauts and cosmonauts on the space station.
