Restoring the sense of touch in amputees using natural signals of nervous system
Scientists have found a way to produce realistic sensations of touch in two human amputees by directly stimulating the nervous system.

Importance of universal sanitation underestimated in efforts to reduce child mortality
The value of sanitation at reducing child mortality in many low income countries has been substantially underestimated, according to recent research.

Ultrasound after tibial fracture surgery does not speed up healing or improve function
Receiving ultrasound after surgery to repair a fractured tibia (shinbone) does not accelerate healing or improve functional recovery compared with sham treatment, finds a trial.

Hormone that controls maturation of fat cells discovered
Mature fat cells produce a hormone that regulates the differentiation of nearby stem cells in response to glucocorticoid hormones and high-fat diets, researchers have found.

STAT2: Much more than an antiviral protein
A protein known for guarding against viral infections leads a double life, new research shows, and can interfere with cell growth and the defense against parasites. In a new paper, researchers describe the duplicitous nature of this essential protein, called STAT2, which they discovered while investigating the mechanisms behind interferon signaling.

After blindness, the adult brain can learn to see again
More than 40 million people worldwide are blind, and many of them reach this condition after many years of slow and progressive retinal degeneration. The development of sophisticated prostheses or new light-responsive elements, aiming to replace the disrupted retinal function and to feed restored visual signals to the brain, has provided new hope. However, very little is known about whether the brain of blind people retains residual capacity to process restored or artificial visual inputs.

Dose of dextrose gel lowers risk of low blood sugar in newborns
A single dose of dextrose gel, rubbed inside a newborn's mouth an hour after birth, can lower their risk of developing neonatal hypoglycaemia, according to a randomized study. The study, designed to investigate the optimal dose and timing for dextrose, is novel in testing dextrose as a preventive rather than treatment for low blood glucose.

Iron supplements in the fight against lead
Lead is a toxic heavy metal that was added to gasoline for use in cars until as recently as 25 years ago. It is particularly harmful to the developing brains of infants, children and teenagers, and the damage it does is irreversible. The situation becomes significantly worse if people are exposed to a high level of lead at the same time as they are suffering from iron deficiency.

Brain surface stimulation provides 'touch' feedback to direct movement
Grasping a cup or brushing hair or cooking a meal requires feedback that has been lost in amputees and individuals with paralysis -- a sense of touch. Researchers have now used direct stimulation of the human brain surface to provide this basic sensory feedback through artificial electrical signals, enabling a person to control movement while performing a simple task: opening and closing his hand.

New immunotherapy technique holds promise for curing food allergies
A new immunotherapy technique has been developed that nearly eliminates the allergic response to peanut and egg white proteins in food-allergic mice, reducing the anaphylactic response by up to 90 per cent with only one treatment.
