Johns Hopkins researchers report that the deletion of any single gene in yeast cells puts pressure on the organism's genome to compensate, leading to a mutation in another gene. Their discovery, which is likely applicable to human genetics because of the way DNA is conserved across species, could have significant consequences...

University of Adelaide researchers have taken a step forward in unraveling the causes of a commonly inherited intellectual disability, finding that a genetic mutation leads to a reduction in certain proteins in the brain. Fuente : http://www.eurekalert.org/pub_releases/2013-11/uoa...

NASA has released a natural-color image of Saturn from space, the first in which Saturn, its moons and rings, and Earth, Venus and Mars, all are visible. The new panoramic mosaic of the majestic Saturn system taken by NASA's Cassini spacecraft shows the view as it would be seen by human eyes. Cassini's imaging team processed...

Researchers have found out why birds are migrating earlier and earlier each year. Experts have long suspected climate change is somehow driving this advancing migration pattern. But new research reveals that individual birds migrate like clockwork -- arriving at the same time each year. However, climate warming is resulting in...

No se nota, pero estos son días ajetreados en la capital de Polonia. Mientras se inauguraba la conferencia de la ONU sobre el cambio climático en el Estadio Nacional, al otro lado del río Vístula se congregaba la extrema derecha polaca para su marcha anual por el Día de la Independencia. Excepto...

The American College of Cardiology and the American Heart Association have released a new clinical practice guideline for the treatment of blood cholesterol in people at high risk for cardiovascular diseases caused by atherosclerosis, or hardening and narrowing of the arteries, that can lead to...

Reconstructing the rise of life during the period of Earth's history when it first evolved is challenging. Earth's oldest sedimentary rocks are not only rare, but also almost always altered by hydrothermal and tectonic activity. A new study has revealed the well-preserved remnants of a complex...

The list of complications from type 2 diabetes is long: vascular and heart disease, eye problems, nerve damage, kidney disease, hearing problems and Alzheimer’s disease. Physicians have long thought of osteoporosis as another outcome. Based on a Mayo Clinic study published in the Journal of Bone...

Pese al alerta temprana del gobierno y a la evacuación de hasta 800.000 personas de áreas vulnerables, el tifón Haiyán (“Yolanda”, para la población local) devastó por completo algunas comunidades y zonas costeras de las centrales islas filipinas de Visayas. Este supertifón de categoría 5, que se...

Pese a que el Comité Olímpico Internacional adhiere a estándares ecológicos, las autoridades de Rusia arremeten cada vez más duramente contra quienes denuncian el costo ambiental de los preparativos para los Juegos Olímpicos de Invierno en Sochi. Desde hace años,  ecologistas locales vienen...

Invisibility cloaking is no longer the stuff of science fiction: scientists have demonstrated an effective invisibility cloak that is thin, scalable and adaptive to different types and sizes of objects. Professor George Eleftheriades and PhD student Michael Selvanayagam have designed and tested a...
