You might think it's something from the movie "Total Recall" but instead researchers are using brain "pacemakers" to regulate diseased signals in the brains of Parkinson's disease patients.

These devices are FDA-approved and in use in 30,000 patients but still not well understood.

Biomedical engineers at Duke University's Pratt School of Engineering have found that stimulation administered by rapid-fire electrical pulses deep in the brain produces what they call an "informational lesion." By relaying a repetitious and therefore meaningless message, constant pulses overwhelm the erratic bursts of brain activity characteristic of disease.

"Periodic bursts in the brains of people with tremor -- which might follow a pattern such as 'pop-pop-pop, silence, pop-pop-pop, silence' -- propa

How well do you know your child's pediatrician? Is he or she board certified in pediatrics, or has he or she ever completed specialty training in the field?

Findings from a new study from the University of Michigan C.S. Mott Children's Hospital's Child Health Evaluation and Research (CHEAR) Unit may prompt parents to find out if their child's physician really is who he claims to be – a board-certified and specialty-trained pediatrician.

The signature of climate change over the past 40 years has been identified in temperatures of the Indian Ocean near Australia.

"From ocean measurements and by analysing climate simulations we can see there are changes in features of the ocean that cannot be explained by natural variability," said CSIRO oceanographer Dr Gael Alory.

Mule deer are giving new meaning to watching out for other mothers' kids. Whitetail deer, not so much.

An intriguing study of mule deer and whitetail deer conducted by the University of Alberta in Edmonton, Canada and the University of Lethbridge, also in Canada, showed that both species responded to the recorded distress calls of fawns, similar to the responses elicited when coyotes attack fawns, with mule deer mothers responding to both whitetail and mule deer calls, even when their own fawn stood next to them.

Recent discoveries regarding the physics of ceramic superconductors may help improve scientists' understanding of resistance-free electrical power.

Tiny, isolated patches of superconductivity exist within these substances at higher temperatures than previously were known, according to a paper by Princeton scientists, who have developed new techniques to image superconducting behavior at the nanoscale.

Children are able to solve approximate addition or subtraction problems involving large numbers even before they have been taught arithmetic, according to a study conducted at Harvard University, by researchers from the University of Nottingham and Harvard.

The study suggests that children do not need to master either the logic of place value or the addition table in order to perform approximate addition and subtraction. Children’s difficulty with learning school arithmetic may stem from the need to produce an exact number when solving problems. Elementary education in mathematics might be improved – and children’s interest in the subject enhanced – if children’s talent for approximate calculation could be built upon in the classroom, the authors suggest.
