Scientists have detected previously unnoticed chemical signals that individual cells in the immune system use to communicate with each other over short distances. The signals the researchers detected

Researchers at the Joslin Diabetes Center have demonstrated for the first time that transplanted muscle stem cells can both improve muscle function in animals with a form of muscular dystrophy and replenish the stem cell population for use in the repair of future muscle injuries.

I just saw some information on a solar icemaker created by some students in San Jose. This is a great invention. The picture I saw was a big device but who cares. Regular commercial icemakers are big as well. It is not shocking that college kids would create something like this since many of them use ice for sports injuries, iced tea, & picnics. Oh yeah some even put their beer on ice. That is a shocking revelation I know. So now that they have broken the ice, this machine will take off. College students will make a better one because of the uses I stated earlier. Ice is expensive too. $2.50 for a small bag is kind of steep when you consider it is just frozen water. I spend about $10 a week on ice for my water cooler which equals about $350 per year for my busy work season.

Protein chips – or ‘protein arrays’ as they are more commonly known – are objects such as slides that have proteins attached to them and allow important scientific data about the behaviour of proteins to be gathered.

Segway inventor Dean Kamen is looking to re-invent the prosthetic arm. IEEE Spectrum caught up with Kamen and one of his “test pilots,” to see the robotic arm (named after Luke Skywalker’s artic

Scientists have identified about two dozen genes that control embryonic stem cell fate. The genes may either prod or restrain stem cells from drifting into a kind of limbo, they suspect. The limbo lies between the embryonic stage and fully differentiated, or specialized, cells, such as bone, muscle or fat.

Killing cancer cells, while leaving normal tissue unscathed, is almost impossible. Nanotechnology may do the trick, but big pharmaceutical companies are far from embracing that strategy. In the meantime, highly-engineered biological molecules will fill the void.

The typical American diet often lacks omega-3 fatty acids despite clinical research that shows their potential human health benefits. Zhiyou Wen, assistant professor of biological systems engineering in Virginia Tech’s College of Agriculture and Life Sciences, found a way to grow these compounds using a byproduct of the emerging biodiesel industry.

Plastic coatings could someday help neural implants treat conditions as diverse as Parkinson’s disease and macular degeneration. The coatings encourage neurons in the body to grow and connect with the electrodes that provide treatment.
