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.

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".

Superhuman Hearing Possible, Experiments Suggest
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.

Drug makes hearts repair themselves
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.
