 UCLA researchers have discovered that a combination of drugs, electrical stimulation and regular exercise can enable paralyzed rats to walk and even run while supporting their full weight on a treadmill.
Published Sept. 20 in the online edition of the journal Nature Neuroscience, the findings suggest that the regeneration of severed nerve fibers is not required for paraplegic rats to learn to walk again. The research may hold implications for rehabilitation after human spinal cord injuries.
"Previous studies have tried to tap into this circuitry to help victims of spinal cord injury," he added. "While other researchers have elicited similar leg movements in people with complete spinal injuries, they have not achieved full weight–bearing and sustained stepping as we have in our study."

 Even in the "oldest old," a little physical activity goes a long way, extending life by at least a few years for people in their mid- to late 80s, Israeli researchers found.
The three-year survival rate was about three times higher for active 85-year-olds compared with those who were inactive.
Indeed, it seems that it is never too late to start," the researchers wrote in Monday's Archives of Internal Medicine, which published the study.

 The unwise practice of routinely prescribing antibiotics to kids suffering from an ear infection is coming to a formal end in Canada.
The Canadian Paediatric Society today instructed doctors to watch and wait for 48 hours before using antibiotics to treat most ear infections in healthy children over six months of age.
About 95 percent of the time, an acetaminophen like Tylenol alone works just as well to treat the kind of ear infection that preschoolers with a cold are prone to, said specialist Dr. Joan Robinson in a statement.
She said the main reason for the treatment change is concern about increasing resistance to antibiotics by over-prescribing them.

 Ozone, the main component of air pollution, or smog, also infiltrates indoor environments like homes and offices. Ozone can be released by ordinary copy machines, laser printers, ultraviolet lights, and some electrostatic air purification systems, all of which contribute to increased indoor ozone levels.
Now, researchers are touting the use of common houseplants as a cheap way to improve indoor air quality and help people breathe easier.
