Researchers explore the potential of an exoskeleton patients can control with their brains
Jose Luis Contreras-Vidal looked on as Roger Rovekamp, wearing a skullcap covered in electrodes, took halting steps, each leg moved by the robotic exoskeleton wrapped around his body.
Surviving fasting in the cold
King penguin chicks survive harsh winters with almost no food by minimising the cost of energy production. A new study, to be presented at the Society for Experimental Biology meeting in Valencia on the 3rd ...
Researchers examine mechanical bases for the emergence of undulatory swimmers
How do fish swim? It is a simple question, but there is no simple answer.
New model finds common muscle control patterns governing the motion of swimming animals
What do swimmers like trout, eels and sandfish lizards have in common? According to a new study, the similar timing patterns that these animals use to contract their muscles and produce undulatory swimming ...
MYO armband to muscle into computer control (w/ video)
Research uses muscle activity to move virtual objects (w/ video)
(Phys.org) —Today's smartphones and computers offer gestural interfaces where information arrives at users' fingertips with a swipe of a hand. Still, researchers have found that most technology falls short in making people ...
The origins of laughter
We know the benefits of laughter on health. But why do we laugh? What are the evolutionary origins of laughter and humour? Steven Légaré has asked these questions and has made them the subject of his master's ...
Smart pens to help control hand tremors

Unique Neandertal arm morphology due to scraping, not spearing: study
(Phys.org) -- The traditional image of Neanderthals as gritty people who spent most of their time out hunting might not be entirely accurate, according to a new study revealing that they may have had to devote ...
Muscling toward a longer life: Genetic aging pathway identified in flies
Researchers at Emory University School of Medicine have identified a set of genes that act in muscles to modulate aging and resistance to stress in fruit flies.
Birds 'flap run' instead if flying over obstacles to save energy
Why don't you ever see baby pigeons? For the same reason you don't see many chicks: they can't fly. It can take months for their partially developed wings and flight muscles to become airworthy, and by then the youngsters ...
Apple peel makes mice mighty
For Popeye, spinach was the key to extra muscle. For the mice in a new University of Iowa study, it was apples, or more precisely a waxy substance called ursolic acid that's found in apple peel.
Positioning enzymes with ease
Virtually all processes in the human body rely on a unique class of proteins known as enzymes. To study them, scientists want to attach these molecules to surfaces and hold them fast, but this can often be ...
Could gene tests tell if kids can be sports stars?
Was your kid born to be an elite athlete? Marketers of genetic tests claim the answer is in mail-order kits costing less than $200.
