Irregular arm swing points to Parkinson’s
PENN STATE (US) — An asymmetrical arm swing—where one arm swings less than the other—is an early sign of Parkinson’s and can be seen in time to begin drugs and other interventions in time to slow the disease’s progression. Continue…

Worms stop and go with human-like circuits
U. MICHIGAN (US) — The strategies used by the tiny C. elegans roundworm to control its motions are remarkably similar to those used by the human brain to command movement of eyes, arms, and legs. (more…)

Snails don’t need slime to get ahead
STANFORD (US) — To move from here to there, a snail crawls using one muscular foot on a layer of self-secreted mucus-like slime. Now it appears the sticky stuff isn’t so essential after all. (more…)

Why animal evolution mirrors wheel design
DUKE (US)—While the evolution from the Neolithic solid stone wheel with a single hole for an axle to the sleek wheels of today’s racing bikes can be seen as the result of human ingenuity, engineer Adrian Bejan says it also represents how animals, including humans, have come to move more efficiently and quicker over millions of years on Earth.

E. coli travel using kayak-paddle motion
YALE (US)—Engineers have for the first time observed and tracked E. coli bacteria moving in a liquid medium with a motion similar to that of a kayak paddle. The findings offer a clearer picture of how bacteria move from place to place and, potentially, how to keep them from spreading. (more…)

Sneaky snake fakes out fish prey
VANDERBILT (US)—The tentacled water snake from southeast Asia has found a way to startle its prey so that the fish turn toward the snake’s head to flee instead of turning away. The fish’s reaction is so predictable that the snake aims its strike at the position where the fish’s head will be instead of tracking its actual movement. (more…)

Slithery science of snake movement
How does an animal move without legs? Animals without legs tend to be long and slender, such as the corn snake above. This allows them to squeeze into spaces under branches and leaves. To move along flat ground, snakes use a variety of limbless “gaits,” analogous to those of the horse, such as the walk, trot, and gallop.

Tango improves mobility in Parkinson’s patients
WASHINGTON-ST. LOUIS (US)/strong>—Dancing the tango may improve balance and mobility in people with Parkinson’s disease. A study by researchers at Washington University School of Medicine in St. Louis shows that patients who took part in regular tango classes for 20 sessions showed significant improvements when compared to those who did conventional exercise.
