Un equipo internacional de científicos ha descubierto un mecanismo por el cual la reprogramación de células adultas a células madre pluripotentes inducidas es mucho más rápida y eficiente. El descubrimiento permite que la reprogramación de células pase de un par de semanas a pocos...

Long-lived deep-sea corals preserve evidence of a major shift in the open Pacific Ocean ecosystem since around 1850, according to a study by researchers at UC Santa Cruz. The findings indicate that changes at the base of the marine food web observed in recent decades in the North Pacific Subtropical Gyre may have begun more...

Researchers from the University of Houston have found a catalyst that can quickly generate hydrogen from water using sunlight, potentially creating a clean and renewable source of energy. Their research, published online Sunday in Nature Nanotechnology, involved the use of cobalt oxide nanoparticles to split water into hydrogen...

Resolving a fundamental question in cell biology and showing off the powers of new high-resolution 3-D imaging, NIH scientists have discovered where the Golgi apparatus, which sorts newly synthesized proteins for transport inside and outside the cell, goes when it disassembles during cell division....

Researcher will report additional evidence indicating that the massive brain cell death of Alzheimer's disease is result of mature neurons mistakenly re-entering the cell cycle. They fail to divide and eventually die. Fuente : http://www.eurekalert.org/pub_releases/2013-12/asf...

In lab cultures of mammalian cells, researchers showed that influenza A infection could be controlled by targeting viruses' dependence on cellular glucose. Boosting glucose concentrations concomitantly increased influenza infection rate, and treating viral cells with glucose metabolism inhibitor...

Experimental drug that targets macrophages, a type of immune cells, in microenvironment surrounding lethal brain tumor glioblastoma multiforme decreased cancer's growth and extended survival of lab mice with cancer. Researcher said results are encouraging for planned clinical trials of drug in...

The first 'E-Waste World Map' has been created by UN organizations, industry, governments, non-government and science organizations through their 'Solving the E-Waste Problem (StEP)' initiative.By 2017, world volumes of end-of-life e-products is expected to be 33 percent higher than 2012 and weigh...
