Topological insulators could exist in six new types not seen before. Topological insulators -- materials whose surfaces can freely conduct electrons even though their interiors are electrical insulators -- have been of great interest to physicists in recent years because of unusual properties that...

A new article demonstrates that chloride levels are abnormally elevated from birth in the neurons of mice used in an animal model of autism. Researchers show for the first time that oxytocin, the birth hormone, brings about a decrease in chloride level during birth, which controls the expression of...

Un medicamento administrado en un modelo murino de autismo impide el comportamiento asociado a la enfermedad en su descendencia.

Researchers have discovered how etoposide -- a drug widely used in the treatment of lung and testicular cancers, leukemias and brain tumors -- could increase its efficiency and specificity in combination with other compounds that interfere with cell division. Fuente :...

A team of scientists last year presented evidence of a correlation between the migration patterns of ocean salmon and Earth's magnetic field, suggesting it may help explain how the fish can navigate across thousands of miles of water to find their river of origin. This week, scientists confirmed...

A cure for type 1 diabetes has long eluded even the top experts. Not because they do not know what must be done -- but because the tools did not exist to do it. But now scientists, harnessing the power of regenerative medicine, have developed a technique in animal models that could replenish the...
