Have you ever watched a mile-long freight train rumble by and wondered how one locomotive can pull more than a hundred fully loaded cars? The locomotive weighs maybe 150 metric tons, and each car is about 100 metric tons, which means it's hauling 10,000 tons. I mean, if you weigh 170 pounds, this would be like pulling three SUVs totaling 12,000 pounds.

The brain is the conductor of the orchestra, the muscles are the instruments. When your body is out of alignment, the orchestra is playing out of tune. Misalignment in the musculoskeletal system is frequently the root cause of chronic pain and the resulting poor posture.

An exoskeleton is a relatively new class of wearable device designed to enhance, support, or assist human movement, strength, posture, or even physical activity. The main piece goes around your waist like a belt, and from it, a pair of hinged, mechanized splints extend down over the hips to strap onto each thigh, where they provide some robotic assistance to normal movements like walking, running, or squatting.

Tuning frictional behavior on the fly has been a long-standing engineering dream. This new insight into how surface geometry governs slip pulses paves the way for tunable frictional metamaterials that can transition from low-friction to high-grip states on demand.

For runners, the hips can be one of the most confounding and frustrating parts of the physiological puzzle for efficient movement. Every runner knows how crucial hip strength is - and how mobile hips are essential for both fast and pain-free running. Yet healthy, happy hips remain elusive. For many of us, our hips stay stiff no matter how much we massage and stretch them.

In the run-up to this year's Winter Olympics, and even as the Games have got underway, a scandal has been brewing: allegedly, some competitive ski jumpers may have artificially enlarged their crotch area by injecting their genitals with engorging chemicals or stuffing their underwear to create bigger bulges. The apparent reason: to alter their suit measurementsski jumpsuits are precisely tailored to jumpers' bodiesand, reportedly, to gain a boost in jumps. The allegations, first reported by a German media outlet and since dubbed Penisgate, have caught not only the Internet's attention but also the World Anti-Doping Agency's eye, although no athletes have been implicated by name.

It's just what it looks like: I time my planks then file them away, determined to last a little longer tomorrow. And sometimes I do, for several days in a row, then one day I'll collapse nearly a minute short of my personal best. I'll pound the mat like Charlton Heston at the end of Planet of the Apes, then I'll get myself together - you've got to stay cool at Equinox - and move on with my day.
