UCLA-engineered stem cells seek out and kill HIV in living organisms

Soon, stem cell therapy could be cytotoxic to cells infected with viruses.

Not only HIV, but CMV, EBV, HepB, and others could have a cure.

Fullerene C60 administration doubles rat lifespan with no toxicity

It turns out it wasn't an apple a day that keeps the doctor away, it's a Buckyball.

Fullerene C60 administration doubles rat lifespan with no toxicity

Researchers at the University of Paris and colleagues fed the molecule fullerene (C60 or "buckyballs") dissolved in olive oil to rats and found it almost doubles their lifespan, with no chronic toxicity.

The results suggest that the effect of C60, an antioxidant, on lifespan is mainly due to the attenuation of age-associated increases in oxidative stress, according to the researchers.

Pharmacokinetic studies show that dissolved C60 is absorbed by the gastro-intestinal tract and eliminated in a few tens of hours.

"These results of importance in the fields of medicine and toxicology should open the way for the many possible biomedical applications of C60 including cancer therapy, neurodegenerative disorders, and aging," the researcher suggest.

"C60 can be administered orally, and as it is now produced in tons, it is no longer necessary to resort to its water-soluble derivatives, which are difficult to purify and, in contrast to pristine C60, may be toxic.

Since 1993, countless studies showed that fullerene (C60) and derivatives exhibit paramount potentialities in several fields of biology and medicine, mainly including specific DNA cleavage, imaging, UV and radioprotection, antiviral, antioxidant, and anti-amyloid activities, allergic response and angiogenesis inhibitions, immune stimulating and antitumor effects, enhancing effect on neurite outgrowth, gene delivery, and even hair-growing activity, a summary in the Biomaterials paper stated.

Report: Wearable Computing Will Soon Intensify The Platform Wars

When you think about the popularity of image modification technology like Instagram- tools that  can make memories of places more vivid or more emotional - when Augmented Reality glasses are debuted, how many people do you think might choose to live in a permanently "rose tinted" world?  Every day could be differently everything looks like the world is in a 1920s movie...the next, everyone is beautiful...the next, you are living in the world as seen through the eyes of Renoir's paintings.  

Will people choose to see the reality of their spouse - or choose to always see the "Old Spice Man - the man your man could smell like" or the Spice girls and try a different one each day?  

Who will be staying in reality?

Amazon's Cloud Now 1% of Internet Traffic

An anonymous reader writes "A Wired story claims Amazon's cloud now hosts enough companies and traffic to generate 1% of all Internet traffic (and visits from 1/3 of daily Internet users). An amazing number if true. And a little scary for one company to host this much cloud infrastructure."

Brain Implants Help Paralyzed Monkeys Get a Grip

It feels like the Holy Grail of spinal medicine.  Each announcement seems to put us just in reach.  Yet when I read them, I cannot help but feel encouraged and sad that Christopher Reeves will not be around to benefit from them.

Brain Implants Help Paralyzed Monkeys Get a Grip

sciencehabit writes "Spinal cord injuries cause paralysis because they sever crucial communication links between the brain and the muscles that move limbs. A new study with monkeys demonstrates a way to re-establish those connections. By implanting electrodes in a movement control center in the brain and wiring them up to electrodes attached to muscles in the arm, researchers restored movement to monkeys with a temporarily paralyzed hand. The work is the latest promising development in the burgeoning field of neuroprosthetics."

Wind Turbine Extracts Water From Air

The son evaporates millions of gallons of seawater a day. One can experience this driving through the dense fog in Abu Dhabi desert every night.  How long until we can harvest this moisture and reclaim our deserts?

Wind Turbine Extracts Water From Air

An anonymous reader writes "Getting access to enough water to drink in a desert environment is a pretty tough proposition, but Eole Water may have solved the problem. It has created a wind turbine that can extract up to 1,000 liters of water per day from the air. All it requires is a 15mph wind to generate the 30kW's of power required for the process to happen. The end result is a tank full of purified water ready to drink at the base of each turbine."
