A study published in the latest issue of Restoration Ecology finds that in coastal Louisiana, oyster reefs help to deter erosion. Oyster reefs are self-sustaining, and are additionally attractive because they use native materials, have the potential for long-term growth, and contribute to overall ecosystem stability and quality. Oyster larvae move in groups and water-borne chemicals stimulate the oysters settlement; reefs are therefore able to maintain themselves as new recruits settle and grow. "Sustainability is an important component to note as maintenance requirements would likely be reduced on created oyster shell reefs as opposed to other heavier shoreline protection structures (i.e. limestone rock breakwaters) which usually necessitate placement of additional material over time to maintain their effectiveness," authors, Bryan P. Piazza, Patrick D. Banks, and Megan K. La Peyre state.
The authors evaluated the effectiveness of six experimental shell reefs on both low and high wave energy shorelines in coastal Louisiana. The areas chosen were conducive to oyster habitation, evidenced by the abundance of oyster shells in surrounding waters. Measuring erosion over a year, the authors found that their small, fringing oyster shell reefs were effective in slowing erosion for low wave energy shorelines, though less effective in higher wave energy environments. The authors conclude that "…the use of small created fringing oyster shell reefs has the potential to provide a useful shoreline stabilization tool to coastal managers under low energy environments."

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...
