King David's palace uncovered in Judean Shephelah

Posted: 21 Jul 2013 06:50 PM PDT

King David's Palace has just been uncovered in the Judean Shephelah. Royal storerooms were also revealed in the archaeological excavation. These are the two largest buildings known to have existed in the tenth century BCE in the Kingdom of Judah.

Failure to destroy toxic protein -- not buildup of protein itself -- contributes to Huntington's disease

Posted: 21 Jul 2013 01:17 PM PDT

Recycling is not only good for the environment, it's good for the brain. A study using rat cells indicates that quickly clearing out defective proteins in the brain may prevent loss of brain cells.

Climate friendly fuel cells for hydrogen cars have come one step closer

Posted: 21 Jul 2013 01:17 PM PDT

Climate friendly fuel cells for hydrogen cars have come one step closer. Researchers have shown how to build fuel cells that produce as much electricity as current models, but require markedly less of the rare and valuable precious metal platinum.

Multiple sclerosis research could help repair damage affecting nerves

Posted: 21 Jul 2013 01:17 PM PDT

Multiple sclerosis treatments that repair damage to the brain could be developed thanks to new research. A study has shed light on how cells are able to regenerate protective sheaths around nerve fibers in the brain.

Mirror, mirror on the wall, who has the lowest noise of them all

Posted: 21 Jul 2013 01:17 PM PDT

Scientists have demonstrated a novel "crystalline coating" technique for producing low-loss mirrors. This technology will further accelerate progress in the development of narrow-line width lasers.

Current efforts will not save the world's most endangered cat

Posted: 21 Jul 2013 01:17 PM PDT

Almost 100 million euros has been spent so far on conservation efforts for the last 250 remaining Iberian lynxes in the wild. But the charismatic species is likely to go extinct within 50 years because the current management plans do not account for the effects of climate change. If they did, the population might increase instead concludes a new international study. The study highlights the importance of integrating climate models in management plans for biodiversity.

A first in front-line immunity research

Posted: 21 Jul 2013 01:17 PM PDT

Researchers have gained new insight into the early stages of our immune response, providing novel pathways to develop treatments for diseases from multiple sclerosis to cancer.

Helping robots become more touchy-feely, literally: Paper-thin e-skin responds to touch by lighting up

Posted: 21 Jul 2013 01:17 PM PDT

Engineers have created a new e-skin that responds to touch by instantly lighting up. The more intense the pressure, the brighter the light it emits. The material is the first sensor network on flexible plastic that is user-interactive.

Common stem cell in heart and lung development explains adaption for life on land

Posted: 21 Jul 2013 01:17 PM PDT

Biologists have known that the co-development of the cardiovascular and pulmonary systems is a recent evolutionary adaption to life outside of water. Researchers show that the pulmonary vasculature develops even in the absence of the lung. Mice in which lung development is inhibited still have pulmonary blood vessels, which revealed to the researchers that cardiac progenitors, or stem cells, are essential for cardiopulmonary co-development.

A bad alliance: Rare immune cells promote food-induced allergic inflammation in the esophagus

Posted: 21 Jul 2013 01:17 PM PDT

Until recently, how EoE, a food allergy-associated disease, developed was unclear, but a new study shows that a type of rare immune cell and specific reactions to allergenic foods team up -- in a bad way. This association does point to new ways to possibly treat inflammation associated with EoE.

Making big 'Schroedinger cats': Quantum research pushes boundary by testing micro theory for macro objects

Posted: 21 Jul 2013 01:17 PM PDT

Since Erwin Schroedinger's famous 1935 cat thought experiment, physicists around the globe have tried to create large scale systems to test how the rules of quantum mechanics apply to everyday objects. Researchers recently made a significant step forward in this direction by creating a large system that is in two substantially different states at the same time.

Ancient ice melt unearthed in Antarctic mud: 20 meter sea level rise, five million years ago

Posted: 21 Jul 2013 01:15 PM PDT

Global warming five million years ago may have caused parts of Antarctica's large ice sheets to melt and sea levels to rise by approximately 20 meters, scientists report.

Flip of mitotic spindle has disastrous consequences for epithelial cells

Posted: 21 Jul 2013 01:14 PM PDT

Investigators have used genetics and live cell imaging to illuminate molecular mechanisms that position the cell division machinery in growing tissues.

Sex chromosome shocker: The 'female' X a key contributor to sperm production

Posted: 21 Jul 2013 01:13 PM PDT

Painstaking new analysis of the genetic sequence of the X chromosome -— long perceived as the "female" counterpart to the male-associated Y chromosome -— reveals that large portions of the X have evolved to play a specialized role in sperm production.
