Martxoaren 11n lau urte beteko dira Fukushimako zentral nuklearra lehertu zenetik. Ikerlariak bat datoz historiako istripu nuklearrik kutsagarriena izan dela, baina ez dira ados jartzen izango dituen ondorioez. Orain arteko ondorioak ebaluatzea, berriz, zaila da, erradiazioak ez diolako momentuz isurtzeari utzi, nola airean hala uretan.

Los resultados de un experimento apuntan a que el hierro llegó al manto tras violentas colisiones que formaron grandes nubes alrededor del planeta. Los modelos predecían que el hierro debía caer hacia el núcleo, pero el metal se acumuló por acreción.

The vibrant red leaves on the pond in Vincent van Gogh’s Wheat stack under a cloudy sky are slowly transforming into the colour of the clouds above. Now, scientists in Belgium may have found the missing chemical link to explain why these reds are turning white.

Humans diverge from economic rationality. Researchers have found that all sorts of logically inconsequential circumstances—rain, sexual arousal (induced and assessed by experimenters with Saran-wrapped laptops), or just the number “67” popping up in conversation—can alter the value we assign to things.

Breakthrough as scientists in China produce genetically modified animals that are more difficult to infect with tuberculosis

Researchers at Princeton University and their colleagues recently reported in the journal Science that termite mounds may serve as oases in the desert, allowing the plants that surround them to persist on a fraction of the annual rainfall otherwise required and to bounce back after a withering drought. The mounds could thus prove potential bulwarks…

Astronomoek lehen aldiz behatu dute litio elementuaren sorrera nova leherketa batean

For years some physicists have been hoping to crack the mystery of high-temperature superconductivity—the ability of some complex materials to carry electricity without resistance at temperatures high above absolute zero—by simulating crystals with patterns of laser light and individual atoms. Now, a team has taken—almost—the next-to-last step in such «optical lattice» simulation by reproducing the…

High above the spiral Milky Way, astronomers have spotted two clusters of new stars growing at the fringes of our galaxy. The discovery, published in the journal Monthly Notices of the Royal Astronomical Society, appears to be the first such stellar cradles found outside the galactic disk.
