Slicing through the water at speeds exceeding 45 miles per hour (72 kph), the shortfin mako shark is one of the fastest fish in the sea. A team of Harvard biologists has made a surprising discovery about what feature gives the mako, like all other sharks, its incredible swiftness — its sandpapery skin.
As temperatures drop and days grow shorter, middle and high school students across the country begin gearing up for science fair season. While these competitions typically take place in the spring, the qualifying projects can take several weeks or even months to plan, carry out and summarize. That means late fall and early winter are an ideal time for students to start brainstorming project ideas.

It's not just Daylight Savings Time that came early this year. All around the world, spring seems to be coming sooner than it used to. It hasn't moved up on the calendar — but many cycles in nature are telling us that spring just can't wait to be sprung.
The human body is regulated by several internal clocks, which control sleeping and eating patterns among other things.
Try this: For an entire day, forget about the clock. Eat when you’re hungry and sleep when you’re tired. What do you think will happen?
Until recently, the solar system was made up of the sun (far left) and nine planets, including (from left to right) Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto -- so small in comparison that it is difficult to make out in this
These images show the first plutoids. The blue blob is Pluto. The red one is Eris. Both objects lie far from Earth, beyond Neptune, and are large enough that gravity pulls them into spherical forms. Other bodies that are similar will one day be called plu
Health experts have long worried about the increasing rate of obesity in kids. It's an important concern: Being very overweight or obese during childhood can lead to serious problems normally seen in adults, such as diabetes and high blood pressure. Poor diets and a lack of exercise are usually the culprits. But would you ever have imagined there might be a connection between the bacteria that lived in your gut when you were a baby and the chance that you would become overweight?
Scientists in Finland recently found just such a link. In a recent study, they showed that as infants overweight children had different species of bacteria living in their guts, or intestines, than did normal-weight kids.
It's hard to believe today, but millions of years ago the dusty New Mexico desert was covered by a shimmering ocean. That ocean water evaporated long ago. But it left behind huge deposits of salt. Some of those salt deposits contain tiny pockets of trapped ancient ocean water—super salty time capsules of an era before dinosaurs ever walked on Earth.
It sounds like the beginning of a mystery movie: Last month, researchers traveled to the French countryside in search of hidden works of art.
But this is no Hollywood blockbuster—at least not yet. It's a real-life mystery being tackled by a team of engineers, art historians, and computer scientists.
They've come to a centuries-old church to look at sections of an old and valuable picture painted onto the church's stone walls. Local residents uncovered this painted mural in the church of St. Jean the Baptist in Vif, France. It had been hiding beneath layers of painted plaster for hundreds of years.
Try to wrestle an alligator underwater, and you'll probably lose. It's not just that the average gator—at 11 feet long and close to 1,000 pounds—is a whole lot bigger than you are. It turns out alligators have a secret weapon when it comes to moving up, down, and around in the water. Nobody recognized it until now, but alligators actually move their lungs to help them dive, surface, and roll.
