Scientists from around the world joined this Greek islands 250 residents and countless visitors Wednesday in cheering the drama of the Moon totally blocking the Sun, revealing the dancing glow of its corona.
"It was even more fabulous than we expected," said Jay Pasachoff, professor of astronomy at Williams College (in Williamstown, Mass.) who observed his 42nd solar eclipse. "All the technical equipment worked perfectly, the corona shone brightly, and the activity around sunspots on the eastern edge of the Sun provided an even more dramatic show than predicted."
Chair of the International Astronomical Unions Working Group on Eclipses, Pasachoff led an expedition of dozens of scientists and students to record images from the rare, three-minute event. They are capturing data over many eclipses to understand better why the Suns corona, the outer halo of million-degree gas, shines hotter than the Sun itself. Most of the corona is visible from Earth only for the fleeting time that the Moon totally blocks the Suns direct rays.

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...
