Observations of Titans atmosphere offer a unique look at how Saturns giant moon compares to Earth.
Titan is the only moon in the solar system with a substantial atmosphere. Like Earth, Titans atmosphere is primarily composed of nitrogen, but unlike Earth, one of the most abundant constituents is methane (CH4). The Huygens probe will determine if the abundance of argon exceeds that of methane. Methane, the main component in natural gas, plays a key role in the make-up of atmospheric conditions on Titan.
The organic chemistry that occurs in Titans atmosphere is an analog of the processes that may have been present in the early terrestrial atmosphere. The research appears in the May 13 edition of the journal Science. Using an infrared spectrometer on the Cassini-Huygens Spacecraft, researchers have measured the temperature, winds and chemical composition of Titan.

New research identifies how 3-D printed metals can be both strong and ductile

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...
