Evolution skeptics argue that some biological structures, like the eye, are too complex for natural selection to explain. Biologists have proposed various ways that so-called "irreducibly complex" structures could emerge incrementally over time. But a new study proposes an alternative route. Fuente...

Why do some memories last a lifetime while others disappear quickly? A new study suggests that memories rehearsed, during sleep or waking, can have an impact on memory consolidation and on what is remembered later. A new study shows that when the information that makes up a memory has a high value,...
Like finally seeing the gears of a watch and how they work together, all components of an entire telomerase enzyme complex have been positioned into a three-dimensional structure for the first time. This first complete visual map of the telomerase enzyme complex, known to play a significant role in...
Muchas son las iniciativas para reducir el consumo de tabaco, como la inclusión de imágenes en las cajetillas. Sin embargo, expertos de la Universidad de Granada sostienen que no tienen el impacto deseado en los fumadores, porque solo a una parte de ellos les parecen realmente desagradables. Fuente :...

Científicos españoles han demostrado que la hormona FNDC5/IRISINA, una proteína secretada por el músculo que transforma la grasa blanca en parda, es también segregada por el tejido adiposo blanco. La grasa blanca sería la responsable de los niveles elevados de irisina en casos de obesidad, en los que podría existir una...
Un equipo del Instituto Universitario de Nanociencia de Aragón (INA, Universidad de Zaragoza) ha diseñado y patentado un 'diafragma' que separa el hidrógeno del oxígeno con más pureza y menor gasto energético que los actuales. Las empresas Acciona Energía e Ingeteam ya los han utilizado. Fuente :...
Investigadores e ingenieros llevan 25 años tratando de evitar el problema de que el láser de semiconductor emita luz irregular o caótica. Sin embargo estudios recientes demuestran que ese 'caos' ofrece nuevas posibilidades que permitirían resolver importantes problemas en las tecnologías de la información y las comunicaciones...

Tropical Cyclone Victoria is now a remnant low pressure area in the Southern Indian Ocean after running into strong wind shear that has been tearing the storm apart. When NASA's TRMM satellite passed over the storm on April 12, it saw limited areas with moderate rainfall pushed far from the center of circulation. Fuente :...
TUM CREATE has unveiled an all-new multipurpose scooter prototype, codenamed VOI, at the 3rd Taiwan International Electric Vehicle Show. VOI gets its name from the Vietnamese word for elephant -- a symbol of a safe and intelligent mean of transport. It is a two-wheel concept vehicle jointly developed by students from Technische...
A new procedure that thickens and thins fluid at the micron level could save consumers and manufacturers money, particularly for soap products that depend on certain molecules to effectively deal with grease and dirt. Researchers at the University of Washington published their findings online April 9 in the Proceedings of the...
