We have no idea why this happens — but we do have hypotheses.
Nobody likes oil in their water.
Powered by the Moon’s pull, Earth’s oceans generate a magnetic field all of their own.
It’s a trove of valuable data, but we’re still just scratching the surface.
As the Earth heats up, much of the heat sinks into the oceans.
This summer in Poland, two treasure hunters discovered what they believe was a WWII Nazi train filled with treasure, in a buried tunnel. Poland’s Deputy Culture Minister Piotr Zuchowski said authorities were led to the spot and that he was 99% convinced that the treasure had been located. But according to scientists Krakow’s AGH University of Science and Technology, we shouldn’t believe
Using low-frequency laser pulses, a team of researchers has carried out the first measurements on a mineral called herbertsmithite. This (pretty awesome looking) mineral features a unique kind of magnetism. Insite it, magnetic elements constantly fluctuate, leading to an exotic magnetic state, unlike conventional magnetism in which all magnetic forces allign in the same direction and also unlike antiferromagnets, where
A team of researchers from Cologne, Munich and Dresden have managed to create artificial magnetic monopoles, similar in many ways to a fundamental particle postulated by Paul Dirac in 1931. Monopoles and Dipoles Until now, a magnetic monopole, the magnetic analogue to an electric charge has never been observed – all we had until now were dipoles: magnetic bodies which
It saddens me to see NASA having to come out again and explain why the whole ‘Mayan end of the calendar apocalypse’ thing; the US space agency came out with on Saturday in an attempt to debunk these claims and downplay concerns that the world will end in 2012. Mr Don Yeomans from NASA explains that all these concerns rely
Ever since researchers started studying the Earth’s spin, they noticed that the spin isn’t perfect. Many believe this is a result of the different elements in the Earth’s core, mantle and crust, which have different densities and generate different friction. Most researchers studying this wobble agreed that the mantle would have to respond to the magnetic tug of the core
Graphene is probably the ‘substance of the century’, and it will probably be for us what plastics were in the 1900s. Now, a flower-like defect in the material that can occur during the fabrication process could have a significant effect on graphene’s already impressive mechanical, magnetic, and electrical properties. Amazing graphene Graphene is practically a one atom thick layer of
I was telling you a while ago about the revolutionary material called graphene. Graphene is a one atom thick layer of carbon packed in a honeycomb lattice. Now, a team led by Professor Andre Geim, recipient of the Nobel Prize for graphene, showed that electric current (which is basically a flow of electrons) can magnetise the material. This could lead
Yellowstone is without a doubt one of the most fascinating places on the face of the planet. But it doesn’t only attract families or people who want to relax, but it attracts scientists as well, and among them, geologists and geophysicists hold a top spot. University of Utah researchers made the first large-scale picture of the electrical conductivity of the
A huge plasma eruption that took place on the Sun has caused a “solar tsunami” of ionized atoms that are on a course for our planet on Tuesday night. Nothing to be too alarmed here, except for the disruption of some satellites. It will however generate quite a show, a rare and unpredictable one too. “It’s the first major Earth-directed
The US-Japan Sukazu observatory reported the finding of some never-before seen embers from the high temperature fireballs that immediately follower the supernovae explosions. Even after thousands of years in which they haven’t been exposed to any heat source, gas within these stellar wrecks is 10.000 hotter than the Sun’s surface. “This is the first evidence of a new type of
