The idea was too beautiful to be wrong. That you could start with nothing, apply some basic laws of physics, and get auniverse out of it—a universe that was uniform on the largest scales but replete with the lumps and bumps we call stars and galaxies, a universe, that is, that looks like ours—well, it…

Ebolari aurre egiteko behar diren txerto-dosiak datorren urterako prest izan nahi dituela iragarri du MOEk, Genevan egin berri duen bileran. Iragarpena ausarta den arren, laborategiek normalean txertoak garatzeko behar izaten duten denbora-tartea laburtzea lortzen ari dira ebolaren kausan. Hala, dagoeneko bi txerto ari dira probatzen pertsona osasuntsuetan; are gehiago, laster, Afrika mendebaldean proba zabalak egiteko…

The centre of the galaxy looks to be lit up by the death-throes of dark matter. Spotting another of the signals we expect to see from dark matter particles annihilating each other could boost confidence that previous observations were the real deal. It could also offer a new way to examine the properties of the…

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…

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…

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.
