Industria-iraultzaren hastapenetatik metatu ziren poluitzaileak Himalaiako glaziarretan
Industria-iraultzaren ezaugarri nagusietakoa energia-kontsumoa izan zen: ikatza izan zen aldaketa bultzatu zuen erregaia. Orain frogatu dutenez, errekuntza haren aztarnak iraultzaren hasieratik bertatik metatu ziren Himalaiako goi-glaziarretan.
The Grand Unified Theory of Rogue Waves
Rogue waves — enigmatic giants of the sea — were thought to be caused by two different mechanisms. But a new idea that borrows from the hinterlands of probability theory has the potential to predict them all.
Asteroid That Killed the Dinosaurs Was Great for Bacteria
The smoldering crater left by the apocalyptic space rock became a nice home for blue-green algae within years of the impact.
Could a habitable planet orbit a black hole?
Supermassive black holes have a reputation for consuming everything in their path, from gas clouds to entire solar systems. So is there any way aliens could live on a world that actually orbited one of these cosmic beasts? Surprisingly, the answer is a tentative yes, researchers say, although there are plenty of reasons why life could never take hold in such a place. If it did, living on such a planet would be truly surreal, with the black hole filling nearly half the sky and concentrating leftover photons from the big bang into a pseudosun.
Confirmado: la gravedad varía según las estaciones y la meteorología
El campo gravitatorio de la Tierra no es una esfera uniforme y su intensidad va cambiando en función de los cambios estacionales y meteorológicos
Early climate models successfully predicted global warming
Climate models published between 1970 and 2007 provided accurate forecasts of subsequently observed global surface warming. This finding shows the value of using global observations to vet climate models as the planet warms.
The New Video of One of the Scariest Places on Earth
For the first time, scientists have a clear view of the line where the giant Thwaites Glacier is leaking water into the ocean.
Un ejército de medusas biónicas para explorar los océanos
Ingenieros de Caltech desarrollan una prótesis que acoplada a las medusas consigue que naden más deprisa. Es el primer paso para equiparlas con sensores y obtener todo tipo de datos oceánicos.
La mayor amenaza desde que existe el chocolate
De aquí a entre diez y treinta años, el chocolate podría convertirse en un alimento que escasee. Los árboles del cacao del oeste de África, debilitados por el cambio climático, son cada vez más propensos a sufrir epidemias. A los investigadores les preocupa en especial un brote en Ghana de la enfermedad del retoño hinchado.
