Researchers reveal the nova was about 14,800 light years from the sun, meaning the explosion witnessed in August last year happened 15,000 years ago.

It isn’t actually perspiration that causes that dank gym scent but rather the bacteria that thrive off sweat. Good news: A team of Swedish researchers from the KTH Royal Institute of Technology has found a way to eliminate the growth of this smell-inducing bacteria using one of nature’s best antimicrobials, algae. Even better: They’ve created an algae-based material that can prevent both body odor and the bacteria that cause it.

After decades of repeated reinvention, the silicon transistor is starting to show its age, and the industry is hunting for alternatives. One option involves a new way of manipulating the properties of a material that the computer industry already uses. If it works, it would lead to computer processors that are not only more energy-efficient but also capable of both computation and memory storage at once.

El sistema se basa en sensores bioquímicos fáciles de producir y muy baratos. Los investigadores de Harvard que han desarrollado la idea creen que podría ser distribuido en países pobres para detectar la enfermedad.

La anorexia entre los hombres es minoritaria (apenas un 10% de los casos) y pasa más inadvertida que entre las mujeres (niñas, adolescentes, jóvenes, fundamentalmente). Pero a pesar de haber sido un trastorno ignorado durante años, no solo existe; sino que tiene sus particularidades respecto a las chicas.

Las emisiones de gases de efecto invernadero influyen en mayor medida al deshielo que los cambios de la órbita de la Tierra, según un estudio liderado por el Consejo Superior de Investigaciones Científicas.

A deadly winter cold wave settled over Europe at the end of January 2012, blanketing much of the continent with snow and ultimately causing more than 800 deaths. Such severe winters are becoming more common across Eurasia—and some scientists contend that sea ice loss, by altering circulation patterns, is ultimately to blame for these frequent deep chills.

Gravitational waves, invisible ripples in the fabric of space and time, might be detected by looking for the brightening of stars, researchers say.

Radical theory proposes that interactions between classical worlds can explain some quantum phenomena.

Más allá de la anécdota, la tecnología holográfica vive un momento dulce. Aplicaciones para la salud prometen simplificar el diagnóstico médico con dispositivos no mayores que la yema de un pulgar. En el mundo de la informática, estas esculturas de luz pueden llegar a multiplicar en un lustro la cantidad de memoria disponible en los ordenadores.
