Project marks unique collaboration with NASA
NASA’s Far Ultraviolet Spectroscopic Explorer (FUSE) satellite will reach a major milestone on Thursday, June 24, 2004 – the five-year anniversary of its launch atop a Delta-II rocket from Cape Canaveral in Florida.
The 18-foot tall, 3,000 pound satellite continues to operate from its perch nearly 500 miles above the Earth’s surface, gathering unique data about everything from planets and nearby stars to galaxies and quasars billions of light years away. Groundbreaking science done during FUSE’s five years in orbit include a first-ever observation of molecular nitrogen outside our solar system; confirmation of a hot gas halo surrounding the Milky Way galaxy; and a rare glimpse into molecular hydrogen in the Mars’ atmosphere, among other findings. By its fifth anniversary, FUSE will have collected more than 47 million seconds of science data on more than 2,200 unique objects in the cosmos.

Carbon nanotubes (CNTs) are valuable for a wide variety of applications. Made of graphene sheets rolled into tubes 10,000 times smaller than a human hair, CNTs have an exceptional strength-to-mass ratio and excellent thermal and electrical properties. These features make them ideal for a range of applications, including supercapacitors, interconnects, adhesives, particle trapping and structural color.
New research reveals even more potential for CNTs: as a coating, they can both repel and hold water in place, a useful property for applications like printing,...
If you've ever tried to put several really strong, small cube magnets right next to each other on a magnetic board, you'll know that you just can't do it. What happens is that the magnets always arrange themselves in a column sticking out vertically from the magnetic board. Moreover, it's almost impossible to join several rows of these magnets together to form a flat surface. That's because magnets are dipolar. Equal poles repel each other, with the north pole of one magnet always attaching itself to the south pole of another and vice versa. This explains why they form a column with all the magnets aligned the same way.
Now, scientists at ETH Zurich have managed to create magnetic building blocks in the shape of cubes that - for the first time ever - can be joined together to...

In two experiments performed at the free-electron laser FLASH in Hamburg a cooperation led by physicists from the Heidelberg Max Planck Institute for Nuclear physics (MPIK) demonstrated strongly-driven nonlinear interaction of ultrashort extreme-ultraviolet (XUV) laser pulses with atoms and ions. The powerful excitation of an electron pair in helium was found to compete with the ultrafast decay, which temporarily may even lead to population inversion. Resonant transitions in doubly charged neon ions were shifted in energy, and observed by XUV-XUV pump-probe transient absorption spectroscopy.
An international team led by physicists from the MPIK reports on new results for efficient two-electron excitations in helium driven by strong and ultrashort...
