Kidney cancer vaccine successful in clinical trials Posted: 29 Jul 2012 05:50 PM PDT Researchers have completed two successful clinical studies using the kidney-cancer vaccine IMA901.

Graphene re-knits its holes Posted: 29 Jul 2012 12:00 PM PDT Scientists have discovered that the 'miracle material', graphene, undergoes a self repairing process to mend holes.

Record efficiency for next-generation solar cells Posted: 29 Jul 2012 11:23 AM PDT Researchers have made a breakthrough in the development of colloidal quantum dot (CQD) films, leading to the most efficient CQD solar cell ever. The researchers created a solar cell out of inexpensive materials that was certified at a world-record 7.0 percent efficiency.

Researchers analyze melting glaciers and water resources in Central Asia Posted: 29 Jul 2012 11:23 AM PDT Scientists have analyzed climate changes and glaciation in the Tien Shan Mountains (Central Asia), and explained their consequences.

Giant ice avalanches on Saturn's moon Iapetus provide clue to extreme slippage elsewhere in the solar system Posted: 29 Jul 2012 11:22 AM PDT Saturn's ice moon Iapetus has more giant landslides than any solar system body other than Mars. Measurements of the avalanches suggest that some mechanism lowered their coefficients of friction so that they flowed rather than tumbled, traveling extraordinary distances before coming to rest. Scientists who have been studying the ice avalanches suggest a experimental test that might provide some answers.

Cell receptor has proclivity for T helper 9 cells, airway inflammation Posted: 29 Jul 2012 11:22 AM PDT A cell surface molecule, OX40, is a powerful inducer of T helper cells that make copious amounts of interleukin-9. Such TH9 cells are responsible for ongoing inflammation in the airways in the lungs in vivo.

New discovery of how carbon is stored in the Southern Ocean Posted: 29 Jul 2012 11:22 AM PDT Scientists have discovered an important method of how carbon is drawn down from the surface of the Southern Ocean to the deep waters beneath. The Southern Ocean is an important carbon sink in the world – around 40 percent of the annual global CO2 emissions absorbed by the world's oceans enter through this region.

Gene discovery set to help with mysterious paralysis of childhood Posted: 29 Jul 2012 11:22 AM PDT Alternating hemiplegia of childhood is a very rare disorder that causes paralysis that freezes one side of the body and then the other in devastating bouts that arise at unpredictable intervals. Seizures, learning disabilities and difficulty walking are common among patients with this diagnosis. Researchers have now discovered that mutations in one gene cause the disease in the majority of patients with a diagnosis of AHC, and because of the root problem they discovered, a treatment may become possible.

New dimension of physics research: Cutting the graphene cake Posted: 29 Jul 2012 11:21 AM PDT Researchers have demonstrated that graphene can be used as a building block to create new 3D crystal structures which are not confined by what nature can produce. Sandwiching individual graphene sheets between insulating layers in order to produce electrical devices with unique new properties, the method could open up a new dimension of physics research.

Magnetic field, mantle convection and tectonics Posted: 29 Jul 2012 11:21 AM PDT On a time scale of tens to hundreds of millions of years, the geomagnetic field may be influenced by currents in the mantle. The frequent polarity reversals of Earth's magnetic field can also be connected with processes in the mantle. New results show how the rapid processes in the outer core, which flows at rates of up to about one millimeter per second, are coupled with the processes in the mantle, which occur more in the velocity range of centimeters per year.

Chronic 2000-04 drought, worst in 800 years, may be the 'new normal' Posted: 29 Jul 2012 11:21 AM PDT The chronic drought that hit western North America from 2000 to 2004 left dying forests and depleted river basins in its wake and was the strongest in 800 years, but those conditions will become the "new normal" for most of the coming century, scientists conclude in a new report. Such climatic extremes, they say, have increased as a result of global warming.

Elusive gene that causes a form of blindness from birth dlscovered Posted: 29 Jul 2012 11:21 AM PDT Researchers have isolated an elusive human gene that causes a common form of Leber congenital amaurosis (LCA), a relatively rare but devastating form of early-onset blindness. The new LCA gene is called NMNAT1. Finding the specific gene mutated in patients with LCA is the first step towards developing sight-saving gene therapy.

Smell the Potassium: New understanding of trigger for compulsive mating and male-on-male death matches Posted: 29 Jul 2012 11:21 AM PDT Scientists have made a surprising find in study of sex- and aggression-triggering vomeronasal organ.

Bone tissue engineering: Attaching proteins for better regeneration Posted: 29 Jul 2012 11:21 AM PDT Researchers have demonstrated a new protein binding approach for effectively promoting bone regeneration. Current treatments for bone defects and bone tissue regeneration have significant limitations. Now a new method that immobilizes a fusion protein in a hybrid collagen-polymer supportive scaffold shows promise for bone tissue engineering.
