Brief reflections from a plasma mirror

When a dense sheet of electrons is accelerated to almost the speed of light, it acts as a reflective surface. Such a 'plasma mirror' can be used to manipulate light. Now an international team of physicists from the Max Planck ...

Precisely fitting bone implants from the printer

Cancerous tumors, infections or bad fractures can make it necessary to surgically remove bones and insert implants in their place. In collaboration with European partners, Fraunhofer researchers have now developed a technique ...

Macroscopic phenomena governed by microscopic physics

It has been difficult to simultaneously obtain micro- and macroscopic information in outer space. Global images of distant astrophysical phenomena provide macroscopic information, however local information is inaccessible. ...

A new way to create Saturn's radiation belts

A team of international scientists from BAS, University of Iowa and GFZ German Research Centre for Geosciences has discovered a new method to explain how radiation belts are formed around the planet Saturn.

Successful second round of experiments with Wendelstein 7-X

During the course of the step-by-step upgrading of Wendelstein 7-X, the plasma vessel was fitted with inner cladding beginning in September of last year. Graphite tiles are now protecting the vessel walls. In addition, the ...

Waking sleeping plants with plasmas

Commercial crops like grapes, peaches, berries and flower bulbs all go dormant in the winter, essentially sleeping through the seasonal cold before they resume growing, flowering and fruiting again in the warmer months.

Why a stream of plasma makes chemical reactions more efficient

A whiff of plasma, when combined with a nanosized catalyst, can cause chemical reactions to proceed faster, more selectively, at lower temperatures, or at lower voltages than without plasma—and nobody really knows why.
