Those of us with an aversion to needles can soon go to the doctor with a little less trepidation. That is if a new device developed by a team of MIT researchers becomes available at your local medical facility. The device uses a Lorentz-force actuator to create an adjustable high-pressure jet that is ejected out of a nozzle as wide as a mosquito's proboscis, penetrating the skin to deliver highly controlled doses at different depths.

Natural cancer drug available from soaking soybeans

A group of plant scientists at the University of Missouri have discovered a new, inexpensive approach to extracting an powerful anticancer chemical from soybeans. The incidence of a number of common cancers (breast, colorectal, prostate, bladder, lymphoma, and oral cancers) is lower in Japan by a factor of two to ten times than in North America or Western Europe. The medical profession is edging toward a conclusion that a significant portion of the reduction in alimentary system cancers and breast cancer is associated with the importance of the humble soybean to Japanese diets.

One of the myriad of hurdles premature babies must overcome after entering the world too soon is learning how to suck and feed. To address this problem and get premature babies feeding and out of the hospital sooner, Florida State University (FSU) professor Jayne Standley has developed a pacifier that provides musical reinforcement every time the baby sucks on it correctly.

In the most economically excluded regions of the world about 1.5 million children die of dehydration every year. When patients get to hospital for IV therapy, there may not be enough staff to monitor the drip, and the child may die from receiving the wrong amount of fluid, which is also potentially fatal in cases of over-hydration. In order to help health care workers in those places, engineering students at Rice University have developed a prototype of a technically simple yet ingenuous IV drip system that adds an element of automation to the process.

It's been a good news week for those suffering debilitating spinal injuries. First we looked at a breakthrough that enables quadriplegic patients to move robotic arms using just their thoughts and now, in related news, surgeons at the Washington University School of Medicine have reported the successful rerouting of working nerves in the upper arms of a quadriplegic patient, restoring some hand function.

One of the biggest problems in fighting the spread of AIDS has always been convincing people to have themselves tested regularly. Unfortunately, getting someone to take a trip to a clinic isn't always easy, particularly in areas where there aren't many options for discreet testing. In a development that could leap right over this privacy hurdle, the U.S. Food and Drug Administration has just unanimously approved an over-the-counter HIV test that enables people to test themselves in their own home and receive results in just 20 minutes.

New light-powered retinal prosthesis could restore sight to the blind

Age-related macular degeneration is the leading cause of blindness in North America, while retinitis pigmentosa causes approximately 1.5 million people worldwide to lose their sight every year. Individuals afflicted with retinal degenerative diseases such as these might someday be able to see again, however, thanks to a device being developed at California’s Stanford University. Scientists there are working on a retinal prosthesis, that uses what could almost be described as miniature solar panels to turn light signals into nerve impulses. Read More
Protein that stimulates brown fat could boost weight loss strategies
By Darren Quick

For most of us fighting the battle of the bulge, fat is an enemy that must be reigned in to a healthier – and less noticeable – level. But there are actually two types of fat – or adipose tissue – found in mammals, white and brown. While white fat stores calories and is the culprit behind love handles, brown fat’s primary function is to generate heat to keep the body warm through the burning of fats in a process known as thermogenesis. Therefore, the ability to activate brown fat in the body could provide a means to fight obesity and keep the weight off. Now scientists have discovered a protein that could allow them to do just that. Read More

Foodies who've ever dreamed of having superhero-style vision that could analyze what they are about to eat should keep an eye on the upcoming Sensor+Trade fair in Nuremberg. Scientists from the Fraunhofer Institute of Photonic Microsystems (IPMS) will be exhibiting a tiny prototype spectrometer that can measure factors such as water and protein level in foods, meaning you won't make the mistake of buying fruit that looks good on the outside but is rotten at its core.

The Autospense vending machine by a Californian company Dispense Labs LLC is designed to allow easy access to medical marijuana for those who need it, while keeping it safely out of reach of those who merely want it. This machine is far more sophisticated than your average snack dispenser though - locks, cameras, sensors and proprietary software all add up to a high-security turnkey solution for dispensing, tracking and managing medical marijuana.
