Neurosurgery researchers at UC Davis Health System have used a new, leading-edge stem cell therapy to promote the growth of bone tissue following the removal of cervical discs — the cushions between the bones in the neck — to relieve chronic, debilitating pain. The procedure was performed by associate professors of neurosurgery Kee Kim and Rudolph Schrot. It used bone marrow-derived adult stem cells to promote the growth of the bone tissue essential for spinal fusion following surgery, as part of a nationwide, multicenter clinical trial of the therapy. Removal of the cervical disc relieves pain by eliminating friction between the vertebrae and/or nerve compression.

29 July 2011 Last updated at 07:49 GMT By James Gallagher Health reporter, BBC News A jab protecting against all flu viruses is considered a holy grails of vaccine research The first antibody which can fight all types of the influenza A virus has been discovered, researchers claim. Experiments on flu-infected mice, published in Science Express, showed the antibody could be used as an "emergency treatment". It is hoped the development will lead to a "universal vaccine" - currently a new jab has to be made for each winter as viruses change. Virologists described the finding as a "good step forward".

New experiments suggest that just vibrating the ear bones could create shortcuts for sounds to enter the brain , thus boosting hearing. Most people can hear sounds in the range of about 20 hertz (Hz) at the low end to about 20 kilohertz (kHz) at the high end. Twenty kHz would sound like a very high-pitched mosquito buzz, and 20 Hz would be what you'd hear if "you were at an R&B concert and you just stood next to the bass," explained Michael Qin, a senior research scientist at the Naval Submarine Medical Research Laboratory in Connecticut.

Using adaptive optics (AO), the same technology astronomers use to study distant stars and galaxies, scientists can see through the murky distortion of the outer eye, revealing the eye's cellular structure with unprecedented detail.
8 June 2011 Last updated at 17:00 GMT By James Gallagher Health reporter, BBC News More people are surviving heart attacks, but that means more are living with heart failure A drug that makes hearts repair themselves has been used in research on mice. The damage caused by a heart attack had previously been considered permanent. But a study in the journal Nature showed the drug, thymosin beta 4, if used in advance of a heart attack, was able to "prime" the heart for repair.
Mouse stem cells have been coaxed into forming a partial eyeball, and the method may one day lead to retina transplants. Yoshiki Sasai at the RIKEN Center for Developmental Biology in Kobe, Japan, and colleagues encouraged embryonic stem cells to develop into retinal cells, and then grew them alongside a protein matrix to promote the formation of tissue. Over 12 days, the retinal cells formed a vesicle which subsequently transformed into a cup-like structure. Within this "optic cup", six major types of retinal cells were identified. They had spontaneously arranged themselves into six different layers, mimicking those seen in the adult retina.
