The most northerly active volcano on Russias Kamchatka Peninsula is once again erupting, dusting the surrounding snow-white landscape with a wide expanse of dark ash that is visible from 800 km away in space.
This reduced resolution Medium Resolution Imaging Spectrometer (MERIS) image was acquired 11 May 2004 and shows the Kamchatka Peninsula in Russias Far East. The erupting Shiveluch volcano is located towards the right of the peninsula about two thirds of the way up - around it is a circular band of dark ash from the eruption visible over snow.

This image of the Kamchatka Peninsula on Russias East Coast was acquired on 11 May 2004 by the Medium Resolution Imaging Spectrometer (MERIS) instrument on ESAs Envisat satellite in reduced resolution mode.
Two thirds of the way up the Peninsula can be seen a roughly circular band of ash, and at the high point of this band is located the steep-sided 3283-metre-high Shiveluch stratovolcano. An aerial cloud of steam and possibly ash originating from the peak is also faintly visible against the ocean to the east of the Peninsula.

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...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
