Fresh hints of dark matter at Milky Way’s core
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…

Astronomers capture first ever data of an exploding fireball from a nova star
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.

Algae-Based Material Takes On Body Odor
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…

Move Computers Beyond Silicon
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…

La anorexia masculina: ignorada, minoritaria y distinta
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.

La órbita terrestre afecta a la estabilidad de la Antártida
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.

Arctic sea ice loss responsible for Eurasia’s deep chill
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…

Einstein’s Gravity Waves Could Be Found with New Method
Gravitational waves, invisible ripples in the fabric of space and time, might be detected by looking for the brightening of stars, researchers say.
