Científicos del Institut Català de Ciències del Clima han comprobado que la pausa en el calentamiento global detectada en la última década se debe al incremento de la absorción de calor por el océano Atlántico y la banda tropical del Pacífico. De esta forma el efecto de la variabilidad natural del sistema climático...

Según las observaciones más recientes, durante la última década se ha producido una desaceleración del calentamiento global. De todas las hipótesis discutidas por la comunidad científica, los resultados de un estudio publicado en Nature Climate Change, y realizado por un equipo de...

Researchers from the University of Missouri were able to selectively breed rats that exhibited traits of either extreme activity or extreme laziness. They say these rats indicate that genetics could play a role in exercise motivation, even in humans. Fuente :...

Patients who have open heart surgery for heart disease caused by radiation cancer treatment are nearly twice as likely to die in the years following their surgery compared to similar patients who did not undergo radiation treatment, according to new research from Cleveland Clinic published today in...

There's an epic battle taking place that's not on the national radar: intercellular competition. While it's not an Olympic event, new research from UC Santa Barbara demonstrates that this microscopic rivalry can be just as fierce as humans going for the gold.

Families can be key players in a revolution needed to feed the world, and could save money by helping to cut food losses now occurring from field to fork to trash bin, an expert said. He described that often-invisible waste in food — 4 out of every 10 pounds produced in the United States alone — and the challenges of feeding a...

In a discovery suggesting that odors may have a far more important role in life than previously believed, scientists have found that heart, blood, lung and other cells in the body have the same receptors for sensing odors that exist in the nose. It opens the door to questions about whether the heart, for instance, “smells” that...

New research illuminates Thonis-Heracleion, a sunken port-city that served as the gateway to Egypt in the first millennium BC. This obligatory port of entry, known as 'Thonis' by the Egyptians and 'Heracleion' by the Greeks, was where seagoing ships probably unloaded their cargoes to have them assessed by temple officials and...

A new separation process that depends on an easily-distinguished physical difference in adhesive forces among cells could help expand production of stem cells generated through cell reprogramming. The separation process could also lead to improvements in the reprogramming technique itself and expand disease modeling. Fuente :...

Researchers have discovered that stress circuits in the brain undergo profound learning early in life. Using a number of cutting edge approaches, including optogenetics, scientists have shown stress circuits are capable of self-tuning following a single stress. These findings demonstrate that the brain uses stress experience...

Researchers have solved a 60-year-old mystery by identifying a gene that can cause rejection, kidney failure and even death in some blood transfusion patients. In this study they identified the gene that underlies the Vel blood group and will lead to the development of more reliable blood tests and reduce the risk for...
