Autophagy is the major intracellular degradation system by which cytoplasmic materials are delivered to and degraded in the lysosome. However, the purpose of autophagy is not the simple elimination of materials, but instead, autophagy serves as a dynamic recycling system that produces new building blocks and energy for cellular renovation and homeostasis. Here we provide …
SENS (Strategies for Engineered Negligible Senescence) — SENS approaches the diseases and disabilities of aging from an “engineering” point of view. Instead of seeking to decipher the code of life and interfere with metabolic processes (the gerontological approach), or waiting until it is effectively too late to treat age-related damage and treating symptoms (the conventional …
The iPhone 4 has a battery with 3.7 V at 1420 mAh. This is 5.25 watt hours * Amp-hours multiplied by battery voltage will give you watt-hours. Divide by 1000 for kWh. * The energy density of lithium-ion batteries varies from chemistry to chemistry. The specific energy density can range from 100 wh/kg to 125 …
Aluminum Celmet magnified 40 times Sumitomo Electric Industries, Ltd., having newly developed its porous aluminum “Aluminum-Celmet,” has set up a small-scale production line at Osaka Works (1-1-3 Shimaya, Konohana-ku, Osaka) to accelerate development efforts toward mass production of the new material. Aluminum-Celmet can be used to improve the capacity of lithium-ion secondary batteries and capacitors. …
In 2010, I had won two uranium supply bets and one nuclear power generation bets that were made at the Oildrum against Michael Dittmar. TheOildrum has an article about uranium supply and mentions the fact that I won my bets. Michael Dittmar has a new uranium forecast after his last one in 2009 was wrong …
SENS researchers have used vaccination with a human phosphorylated tau immunogen to effect the immunologic clearance of pathological tau aggregates associated with Alzheimer’s disease, in a mouse model expressing wild-type human tau. A vaccine has been effective in clearing the Alzheimer’s related junk from a mouse model. They have intervened late, months after the initial …

Graphene SME Commercialization Strategies: A Cross-Country Comparison (28 pages, April 2011) Although 3,000 related research papers and over 400 patent applications related to the technology were filed in 2010, mass commercialization of graphene may still be years away due to a number of product and process obstacles. 1) cost of development, which will likely decrease …
Science Daily – Johns Hopkins scientists have developed a simplified, cheaper, all-purpose method they say can be used by scientists around the globe to more safely turn blood cells into heart cells. The method is virus-free and produces heart cells that beat with nearly 100 percent efficiency, they claim. Virus-free, iPSC-derived cardiac cells could be …
Known for being the world’s first researcher to have guided a magnetic sphere through a living artery, Professor Martel,Director of the Nanorobotics Laboratory at Polytechnique Montréal, is announcing a spectacular new breakthrough in the field of nanomedicine. Using a magnetic resonance imaging (MRI) system, his team successfully guided microcarriers loaded with a dose of anti-cancer …
Carbon nanotubes are promising elements for optoelectronic components. However so far there were no electronic methods to analyze the ultra fast optoelectronic dynamics of the nanotubes. A team of physicists headed by Professor Alexander Holleitner from the Technische Universitaet Muenchen (TUM) has now come up with a new method to directly measure the dynamics of …
