Artificial magnetic monopoles discovered

A team of researchers from Cologne, Munich and Dresden have managed to create artificial magnetic monopoles. To do this, the scientists merged tiny magnetic whirls, so-called skyrmions. At the point of merging, the physicists ...

Ice cloud heralds fall at Titan's south pole

(Phys.org) —An ice cloud taking shape over Titan's south pole is the latest sign that the change of seasons is setting off a cascade of radical changes in the atmosphere of Saturn's largest moon. Made from an unknown ice, ...

Study says salmon may use magnetic field as navigational aid

The mystery of how salmon navigate across thousands of miles of open ocean to locate their river of origin before journeying upstream to spawn has intrigued biologists for decades, and now a new study may offer a clue to ...

Twin NASA spacecraft deliberately crash into moon

A pair of NASA spacecraft tumbled out of orbit around the moon and crashed back-to-back into the surface on Monday, ending a mission that peered into the lunar interior.

Mars's dramatic climate variations are driven by the Sun

On Mars's poles there are ice caps of ice and dust with layers that reflect to past climate variations on Mars. Researchers from the Niels Bohr Institute have related the layers in the ice cap on Mars's north pole to variations ...

The Titanian seasons turn, turn, turn

(Phys.org) -- Images from NASA's Cassini spacecraft show a concentration of high-altitude haze and a vortex materializing at the south pole of Saturn's moon Titan, signs that the seasons are turning on Saturn's largest moon. ...

Dinosaur forests mapped

The first detailed maps of the Earth's forests at the time of the dinosaurs have been drawn up. The patterns of vegetation, together with information about the rate of tree growth, support the idea that the Earth was stifling ...

How Arctic microbes respond to a warming world

From the North Pole to the Arctic Ocean, the frozen soils within this region keep an estimated 1,672 billion metric tons of carbon out of the Earth's atmosphere. This sequestered carbon is more than 250 times the amount of ...
