Neurosurgeons Use Adult Stem Cells to Grow Neck Vertebrae

Neurosurgery researchers at UC Davis Health System have used a new, leading-edge stem cell therapy to promote the growth of bone tissue following the removal of cervical discs — the cushions between the bones in the neck — to relieve chronic, debilitating pain. The stem cell procedure at UC Davis took place early in August. …

IBM plants transactional memory in CPU

EETimes – IBM has become the first company to ship a commercial microprocessor using transactional memory, a new feature for multicore chips researchers have studied for years. The BlueGene/Q processor used in the Sequoia supercomputer IBM is building for Lawrence Livermore National Labs will employ the new feature, IBM disclosed in a paper at the …

New Uranium recovery from Phosphate process would be almost three times cheaper and could recover 7690 tons of uranium per year from existing phosphate

If the historic uranium recovery from phosphate process were to be revived in the current economic climate, recovery costs would be around $50-70 per pound U3O8 and would be above the current spot market prices for uranium. The PhosEnergy process, however, can deliver low operating costs estimated at $20-25 per pound U3O8 and uranium recoveries …

A new lab on a chip can monitor our driniking water for bioterrorist attacks

Researchers connected to DINAMICS (DIagnostic NAnotech and MICrotech Sensors), a project co-funded by the European commission, have made a lab-on-a-chip device that can monitor our drinking water and spot different pathogens even at very low concentrations. The device uses sensors with very small strands of different pathogenic DNA integrated onto their surfaces to quickly recognize …

Lawrence Berkeley National Labs forecasts peak energy use in China within 20 years because of saturation

AIS is Accelerated Improvement Scenario, CIS is Continued Improvement Scenario, IEA Equiv. refers to converting ERI’s numbers to IEA equivalent given that ERI follows the convention of using power generation equivalent, rather than IEA and LBNL’s use of calorific equivalent, to convert primary electricity. This results in a 3.01 lower gross energy content for renewables …

Neal Stephenson explains why we have been locked into rockets for space launch

What the strange persistence of rockets can teach us about innovation. * $4 trillion was spent to develop rockets for launching nuclear bombs * communication satellites were built to be the same size as the nuclear bombs launched on missiles Dr. Jordin Kare, a physicist and space launch expert, visualizes a triangular feedback loop joining …

Pluripotent stem cells turned into intestinal tissue

Nature – Human intestinal tissue grown in the lab Wells and his collaborators are working on approaches to create intestinal nerve cells in the cultures and transplant the tissue in mouse models of intestinal disorders. They also plan to produce iPS cells from patients with congenital abnormalities and use the culture system to pinpoint what …

Worms achieve longer life through more efficient energy extraction from food

Long-lived mitochondrial (Mit) mutants of Caenorhabditis elegans utilize a novel metabolism The secret to a long life comes from how we extract energy from our food. Scientists compared one class of long-lived C. elegans, called the Mit mutants, with non-mutant wild type C. elegans. Their comparison showed significant metabolism changes, suggesting that their cellular engines …
