Traversing slippery terrain can be a tricky game for a Martian rover -- or any wheeled robot, for that matter. Now, Georgia Tech researchers have built a biologically inspired robot that can speedily navigate slippery, sandy terrain. The 2004 Mars rover Spirit discovered the disadvantages of wheeled travel the hard way when it became stuck in loose soil after six years of navigating all types of terrain. The six-legged robot, described in Friday's edition of the journal Science, could provide a solution for such exploratory vehicles while navigating “flowable” ground.

Ted Vadakan and Angie Myung wanted to outfit their new L.A. boutique, Poketo, with display tables that were not only modern but also inexpensive. Their solution was a cool, custom look that could easily translate as a DIY desk. “I wanted the look to be simple, honest and modern,” said Vadakan, who agreed to share the materials and process with readers. One key, Vadakan said, was a solid-core birch door repurposed as a tabletop. He bought 42-by-80-inch doors, $138 each, from Taylor Brothers Architectural Products in Silver Lake, but stock doors at most hardware stores also would work.

Here are two variations of back arches that will help counter the effects of rounded shoulders. Slouching tends to shorten the muscles in the front of your body and can overstretch the muscles in the back. These moves reverse that action and help improve your posture. Lie face-down on a mat. Bend your knees and bring your heels toward your buttocks. Reach back and grasp each ankle with the same-side's hand. Keep your heels close together and your knees parallel to each other as you inhale and raise your chest and legs away from the floor.

My first experience as a patient proved as instructive as all my classes in medical school. In the autumn of 1979, while training for the Boston Marathon, I developed a nagging ache in my right hip. I assumed I had bursitis, an inflammation around the joint. My self-diagnosis proved drastically wrong. A sports-medicine doctor was the first physician I consulted when the ache slowed my pace. He gave me Indocin, a strong anti-inflammatory medication, for the presumed bursitis.

Speaking with Stephen A. Smith on ESPN Radio in New York , Dwight Howard said his back is at "75%" and his shoulder is "day to day. " The Lakers center sat the last three games after re-aggravating his shoulder injury. The team certainly needs him back on the court with Pau Gasol going down with a torn plantar fascia. "There are days when [my shoulder] feels really good and then I get in the game, get hit and it's not as good," said Howard. "For right now I just have to learn how to play through it and try to mix up my game. I'm known for always coming up and that leaves me vulnerable to guys hitting me, so I'm going to try to play at 75% and keep the ball up here.

Microraptor , a small dinosaur that lived in northeast China about 120 million years ago, had feathers on its wings, hind legs and tail. But in all likelihood, it didn't fly like a bird. Instead, it glided from trees and cruised over “medium distances” - but not very often, according to a study published online Wednesday in Nature Communications. This picture of Microraptor , whose fossils were discovered only 15 years ago, is the result of wind tunnel experiments conducted at the University of Southampton in England.
