(N)ever has a whole-eye transplant been successfully done in a living person. The eye’s complex web of muscles, blood vessels, and nerves — connected directly to the brain — has doomed past experiments to failure. Now a team of Pittsburgh transplant surgeons aims to turn that tide, and they’re hopeful they can do so in…

Speeding Up Muscle Repair
Stem cells, is there anything they can’t do? As you get older your muscles deteriorate. Now scientists are finding improved muscle health after using stem cells. Athletes, the elderly and those with degenerative muscle disease would all benefit from accelerated muscle repair. When skeletal muscles, those connected to the bone, are injured, muscle stem cells…
Stem cell therapy helps paralyzed man regain use of arms and hands
The 21-year-old who suffered a cervical spine injury in March gains significant improvement in his motor function at Keck Hospital of USC after a team of doctors injected an experimental dose of 10 million AST-OPC1 cells directly into patient’s cervical spinal cord in early April 2016. Two weeks after surgery, Boesen began to show signs…
Interscatter communication enables first-ever implanted devices, smart contact lenses, credit cards that ‘talk’ Wi-Fi
University of Washington researchers have introduced a new way of communicating that allows devices such as brain implants, contact lenses, credit cards and smaller wearable electronics to talk to everyday devices such as smartphones and watches. This new “interscatter communication” works by converting Bluetooth signals into Wi-Fi transmissions over the air. Using only reflections, an…
World’s first ‘nanofish’ could be used as guided drug missiles
Engineers have created metallic nanofish that are inspired by the swimming style of real fish, and could be used to carry drugs to specific sites of the body. The nanofish are 100 times smaller than grains of sand, and are constructed from gold and nickel segments linked by silver hinges. The two outer gold segments…
Using light to control genome editing
The genome-editing system known as CRISPR allows scientists to delete or replace any target gene in a living cell. MIT researchers have now added an extra layer of control over when and where this gene editing occurs, by making the system responsive to light. With the new system, gene editing takes place only when researchers…
Fish oil prevents changes induced by a high-fat diet
Scientists have found that fish oil supplements can reverse the effects of a high fat diet according to a study published in the Journal of Physiology. The research from the University of São Paulo shows that giving mice supplement of fish oil prevents or reverses the harmful effects of a high fat diet. This further…
Diet and exercise can reduce protein build-ups linked to Alzheimer’s
A study by researchers at UCLA’s Semel Institute for Neuroscience and Human Behavior has found that a healthy diet, regular physical activity and a normal body mass index can reduce the incidence of protein build-ups that are associated with the onset of Alzheimer’s disease. The study found that each one of several lifestyle factors—a…
Mediterranean Diet
Evidence suggests Mediterranean diet helps you live longer. Latest findings published in Cell magazine can be boiled down to: Mediterranean diet. Composed of healthy fats like olive oil, vegetables, whole grains, nuts and fish, and little red meat or sugar. Caloric restriction. Suggests reduced intake of calories however, balanced so as not to cause malnutrition….
