Accounts of the tsunami that killed over a quarter of a million people in Southeast Asia on the 26th of December, 2004, slowly disappear from the media, but the event is nevertheless heavily burned into the memories of those who are directly involved. In the aftermath of the disaster, academics and politicians alike are trying to investigate how the number of casualties could have been reduced and, more important, how such severe damage can be avoided if a tsunami ever strikes again. In an essay published this week in the June 21 issue of Current Biology, a group of researchers recount the first findings arising from their recent assessment of how mangrove ecosystems might have influenced the tsunamis impacts on coastal communities.

The research represents a collaborative effort, with participants from the Vrije Universiteit Brussel, Belgium; the University of Ruhuna, Sri Lanka; the Kenya Marine and Fisheries Research Institute; and the Institut Français de Pondichéry, India.
Mangrove greenbelts were known to offer some protection against destructive ocean events, such as tsunamis and (far more frequently) tropical cyclones, but they have not always been valued for that function. Economic and political interference, driven by short-term benefit, has been responsible for the destruction of thousands of hectares of mangrove forest (e.g., in East Africa, on the Indian subcontinent, and in Banda Aceh, Indonesia), resulting in the loss of the natural, protective "dyke" function of mangroves in addition to the loss of other services that mangroves provide to local economies and ecosystems. Although many politicians, journalists, and scientists have made post-tsunami statements about the barrier function of mangroves, most have failed to recognize that this function has never actually been investigated in detail.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
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...
