Phys.org / King's Trough: How a shifting plate boundary and hot mantle material shaped an Atlantic mega-canyon

The King's Trough Complex is a several-hundred-kilometer-long, canyon-like system of trenches on the North Atlantic seafloor. Its formation was long thought to be the result of simple stretching of the oceanic crust. An international ...

Medical Xpress / Early signs of Parkinson's can be identified in the blood

A team led by researchers at Chalmers University of Technology, Sweden, has succeeded in identifying biomarkers for Parkinson's disease in its earliest stages, before extensive brain damage has occurred. The biological processes ...

Phys.org / Cleaner ship fuel changed clouds, but not their climate balance

To reduce air pollution associated with ocean transport, the International Maritime Organization tightened restrictions on sulfur content in ship fuel, resulting in an 80% reduction in emissions by 2020. That shift created ...

Phys.org / Atomic spins set quantum fluid in motion: Experimental realization of the Einstein–de Haas effect

The Einstein–de Haas effect, which links the spin of electrons to macroscopic rotation, has now been demonstrated in a quantum fluid by researchers at Science Tokyo. The team observed this effect in a Bose–Einstein condensate ...
