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.
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.

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.
The U.S. government's system for regulating the products of biotechnology, including GMOs, or genetically modified organisms, was born in 1986, and it has been controversial from the start. Now, it will be getting a makeover β in part to assure the public that GMOs really are adequately regulated.

Rearranging veggie genes is big business, and we're not even talking about biotechnology. Private companies and university researchers spend hundreds of millions of dollars every year breeding better genetic varieties of food crops.
But organic farmers say those programs have a big blind spot when it comes to figuring out which new varieties are truly better. Few companies or researchers test those varieties under organic conditions.
