News leads from the USDA FS Southern Research Station
The following are leads for stories on ongoing Forest Service research to restore habitat for the Louisiana pine snake, red-cockaded woodpecker, cerulean warbler, Indiana bat, American eel, and North American freshwater mussels.
Louisiana Pine Snake – Louisiana pine snake, a species of conservation concern, is associated with the longleaf pine forests of the West Gulf Coastal Plain. Craig Rudolph uses radiotelemetry and other methods to study this elusive snake, which many experts believe to be the rarest vertebrate in the United States. Louisiana pine snakes prey mainly on pocket gophers, using their burrows to hibernate. Alteration of the fire regime in the longleaf pine ecosystem in the West Gulf Coastal Plain has led to a decline in the plants that support the pocket gopher, which in turn has led to population declines of the Louisiana pine snake. Roads have also had a significant effect. Habitats are fragmented, and large numbers of snakes are killed by vehicles: data from a recent study suggests that impacts may extend several hundred meters from the road itself.

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...
An international research group has observed new quantum properties on an artificial giant atom and has now published its results in the high-ranking journal Nature Physics. The quantum system under investigation apparently has a memory - a new finding that could be used to build a quantum computer.
The research group, consisting of German, Swedish and Indian scientists, has investigated an artificial quantum system and found new properties.
