Carbon exists in many forms in the air, soil, and water, and is an integral part of most living organisms. In a recent study, Stuart Findlay (Institute of Ecosystem Studies, Millbrook, New York) discovered changes in the amount of carbon in the Hudson River. Exactly why the amounts changed, and what’s causing these changes, remains a mystery.
In "Increased carbon transport in the Hudson River: unexpected consequence of nitrogen deposition?" published in the April issue of Frontiers in Ecology and the Environment, Findlay explores what may be driving this phenomenon.
Most large rivers contain dissolved organic carbon (DOC) in fair quantities, but recent tests have shown a doubling of the amount of DOC accumulating in the Hudson River over the past fifteen years. Soggy peatlands, wetlands, or increased agriculture could all lead to increases in the carbon levels. Some areas have shown increased DOC after nitrogen fertilization of forests. Yet activity along the Hudson River, including agricultural use, has declined over the years.

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...
