In a busy lab at Duke University, Dr. Miguel Nicolelis is merging brain science with engineering in a bid to create something fantastical: a full-body prosthetic device that would allow those immobilized by injury to walk again.
On Wednesday, Nicolelis and an international group of collaborators declared that they had cleared a key hurdle on the path toward that goal, demonstrating they could bypass the body's complex network of nerve endings and supply the sensation of touch directly to the brains of monkeys.

How foreign doctors save lives in rural America
Many rural areas in the US suffer from a shortage of doctors. Unable to attract Americans, they have turned to foreign-born physicians.
The city of Logan in West Virginia has just 1,779 citizens. The nearest large city, Charleston, is an hour away, via winding roads through the Appalachian mountains. Logan is surrounded by rural land, and is in an area which has lost half its population since the 1950s.
27 Years: No Deaths from Vitamins, 3 Million from Prescription Drugs
Over the past 27 years — the complete timeframe that the data has been available — there have been 0 deaths as a result of vitamins and over 3 million deaths related to prescription drug use. In fact, going back 54 years there have only been 11 claims of vitamin-related death, all of which provided no substantial evidence to link vitamins to the cause of death. The news comes after a recent statistically analysis found that pharmaceutical drug deaths now outnumber traffic fatalities in the US.
Genetically Engineered Food: An Overview
Since the 1996 introduction of genetically engineered crops — crops that are altered with inserted genetic material to exhibit a desired trait — U.S. agribusiness and policymakers have embraced biotechnology as a silver bullet for the food system. The industry promotes biotechnology as an environmentally responsible, profitable way for farmers to feed a growing global population. But despite all the hype, genetically engineered plants and animals do not perform better than their traditional counterparts, and they raise a slew of health, environmental and ethical concerns.
3 Reasons to Reconsider Flu Shots
A new major study has numerically determined the effectiveness of the flu shot to be 1%. This means that despite the H1N1-loaded flu jab, there is still a 99% chance that you will not be protected against the flu. The reason for this, despite the faulty science behind the development of the vaccine, has to do with flu strains. It is extremely challenging, to the point of guessing, which flu strain will affect your area. With such a wide selection, it is very rare (about 1%, according to the study), for it to be the correct strain.
Cigarette vending machines banned in England
The sale of tobacco from vending machines has been banned in England, with anyone caught selling cigarettes in machines facing a fine of £2,500.
The Department of Health said the ban had been introduced to prevent under-age sales to children and to support adults who were trying to quit. The rest of the UK is expected to implement a similar ban next year.
Inexpensive system can disinfect water
A new technology using UV light from sunlight can disinfect drinking water for large parts of the world's population easily and cheaply, U.S. researchers say.
A team of Purdue University researchers says the system, in which sunlight is captured by a parabolic reflector and focused onto a UV-transparent pipe through which water flows continuously, could help the world's 800 million people who lack safe drinking water.
