A team of Texas A&M University and Louisiana State University scientists conducted a research cruise in late August to the "dead zone" - a region in the northern Gulf of Mexico that suffers from low oxygen and results in huge marine losses - and much to their surprise, the "dead zone" area had either moved or had disappeared completely.
Steven DiMarco, associate professor in the Department of Oceanography and leader of the team, found that some areas that were previously hypoxic - a technical term for extremely low dissolved oxygen concentrations in water - had broken up and appeared to pose little threat to marine life, while in other areas the hypoxia appeared to have moved further off shore.
Hypoxia can result in fish kills and can adversely affect many types of marine life where it is present. The dead zone area encompassed more than 6,000 square miles this year. "We found that the hypoxia had moved offshore from shallow waters to much deeper waters in the Gulf," DiMarco explains. "In other words, much of the dead zone had broken up, and this very much surprised us."

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...
Transistors based on carbon nanostructures: what sounds like a futuristic dream could be reality in just a few years' time. An international research team working with Empa has now succeeded in producing nanotransistors from graphene ribbons that are only a few atoms wide, as reported in the current issue of the trade journal "Nature Communications."
Graphene ribbons that are only a few atoms wide, so-called graphene nanoribbons, have special electrical properties that make them promising candidates for the...
