Scientists at the University of Edinburgh have identified a protein crucial for maintaining the health and function of the segment of nerve fibres that controls transmission of messages within the brain.The study, published in the journal Neuron, could help direct research into neuro-degenerative disorders, in which electrical impulses from the brain are disrupted. This can lead to inability to control movement, causing muscles to waste away.

On this very day when world observes ‘CANCER DAY’, there is a new hope coming up in the diagnosis of the deadly disease.
Dogs can sniff out bowel cancer in breath and stool samples, with a very high degree of accuracy – even in the early stages of the disease – according to new research published online.
As a result, authors suggest that chemical compounds for specific cancers circulate throughout the body, which opens up the prospect of developing tests to pick up the disease before it has had the chance to spread elsewhere.
A specially trained Labrador retriever completed 74 sniff tests, each comprising five breath (100 to 200 ml) or stool samples (50 ml) at a time, only one of which was cancerous, over a period of several months.The bowel cancer samples came from patients with varying stages of disease, including early stage.
The smell of burnt flesh rises in the operating theatre and the smoke from vaporised tissue is sucked away. But these fumes are diverted into a machine that tells the surgeon exactly what is being cut into, guiding the rest of the operation. This is “smart surgery“, and it holds the potential to transform medicine. This is the first NMR spectrometer in the world which does the work of a histologist.who identifies the tissue being cut/taken out.
For people with memory-degrading conditions like Alzheimer’s, it’s not always easy, or even possible, to remember to take one’s medicine. Yet forgetting to take your meds-or perhaps worse, forgetting that you already took them and doubling up-can derail a dosage schedule and in worse cases be detrimental to your health. So a couple of University of Texas students have come up with a smart digital system that helps the forgetful among us remember to pop our pills and verifies visually that we’ve done so.
By the students’ own admission their Project Smart Pill Box is somewhat rudimentary, which in certain respects is an advantage because the only hardware it requires is a computer and a Web cam, two pieces of technology that are already present in most homes these days.
With telepresence robots serving as stand-ins, there’s no reason for sick kids to miss school. Some children may prefer to skip class, of course, but for those with serious immune system disorders, telepresence ‘bots are a lifeline to the outside world.For the past three weeks, a new telepresence robot has allowed Knox City, Texas, high school freshman Lyndon Baty to interact with classmates, attend lectures and feel like a regular student. He suffers from polycystic kidney disease and had a kidney transplant at age 7. He attended school until last year, but when he started showing signs of transplant rejection, he was forced to stay home because of his suppressed immune system. He wears a surgical mask and must avoid almost all social interactions just to stay healthy.
In December, school district officials heard about the Vgo telepresence robot, a new platform released last year,
