Thanks to one of the most productive spacecraft ever built, scientists are far better acquainted with the star that lights our world and gives us life. Built for ESA by European industry, the Solar and Heliospheric Observatory (SOHO) went into space on 2 December 1995.
The tenth anniversary of SOHO’s launch is a time for celebration for the scientists and engineers in Europe and the USA who conceived, created and still operate this unprecedented solar spacecraft – and who have rescued it from oblivion three times.
Four months after its flawless launch by a NASA rocket, SOHO was at its special vantage point 1.5 million kilometres away from the sunward side of Earth. There it watches the Sun unblinkingly 24 hours every day, and sends home a stream of images of the ceaseless frenzy in the solar atmosphere.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
