Math that powers spam filters used to understand how brain learns to move our muscles

... fine tune new movements, whether babies trying to walk or stroke patients re-connecting brain-body muscle links. In their report this week in Nature Neuroscience, the team says their new tool could make it possible to predict the best ways to teach new movements and help design physical therapy regim...

Lessons from the orangutans: Upright walking may have begun in the trees

... style to incorporate hanging. They only tended to walk on all fours when navigating the largest branches, the researchers found. Hand-assisted bipedalism may have offered several advantages that allowed our arboreal ancestors to venture onto thin branches. They could have gripped multiple branches wit...

First clinical trial of gene therapy for childhood blindness

... was restored to the extent that they were able to walk through a maze without difficulty; something they could not do before the treatment. As this trial is the first to treat an eye disease using administration of gene therapy vectors to human retinas, the team have carried out extensive pre-clinical te...

Robotic exoskeleton replaces muscle work

Cancer researchers add spice to research against rare neuromuscular disease

...ene that causes the disease. The mice were able to walk much more normally, their muscles were much stronger, and they had near-normal levels of a vital molecule crucial for keeping nerve cells healthy. While a great deal more research needs to be done to see if the compound could be developed into a d...

...es by injecting a neurotoxin. The rat's ability to walk was scarcely altered but there was a strong decrease in its ability to respond quickly to obstacles in a reflexive manner. This revealed that specific modules of the cerebellum mainly regulate reflex functions during walking and match these to the si...

How ants find their way

...is is a slow way of travelling as the ant needs to walk with its antennae to the ground. However, this initial route forms the basis of an efficient learning strategy. On the first trip ants store images of the route as they travel and on later trips to the food site will navigate using a combination of l...

Trotting with emus to walk with dinosaurs

...ern Wyoming. Because they are about the same size, walk on two legs and have similar feet, emus turn out to be the best modern version of the enigmatic reptiles that once trotted along a long-lost coastline in the Middle Jurassic. "We don't have any documented dinosaur bones and teeth from that period in...

Dopamine drug leads to new neurons and recovery of function in rat model of Parkinson's

...receiving the treatment to see how well they could walk and reach to retrieve food pellets with their paws. A subset of the rats was tested again 2 and 4 months following the treatment. Rats treated with 7-OH-DPAT had more than twice as many proliferating cells in the substantia nigra as rats that were...

Biological motors sort molecules one by one on a chip

...ecular bio-motors, such as the enzyme kinesin, can walk in small steps (of 8 nanometers) with a load of material along these microtubule-networks and thus provide transport within the cell. Fascinated by these biological motors, the researchers at Delft University of Technology's Kavli Institute of Nan...

Six months after his first amputation, he experienced similar symptoms in his right leg and decided to aggressively pursue amputation alternatives to avoid having to...

Scientists discover dozens of new species in 'Lost World' of western New Guinea
