More than twenty years after the historic Chesapeake Bay Agreement set out a roadmap for a coordinated clean-up effort at state and federal levels, the region is struggling to follow it, scientists say.
Panelists speaking at a February 20 session of the American Association for the Advancement of Science (AAAS) in Washington, DC emphasized the importance of an adaptive approach to restoration in the Chesapeake––which scientists call adaptive management, in which ideas and approaches can be tested, checked for success, and adjusted along the way. "We are headed in the right direction, we know where we want to go, but need to be more efficient and accountable in order to get there," says Donald Boesch, president of the University of Maryland Center for Environmental Science.
And this modify-as-you-go approach to restoration should be "watershedwide," panelists say, including upland streams and rivers, not only the Bay and its living resources––such as crabs, oysters, and underwater grasses. "What happens every day in backyards and on street corners that are miles and miles from the Bay proper have huge impacts on Bay health," according to ecologist Margaret Palmer from the University of Maryland, College Park. "Restoration of the Bay will not occur unless we stem the loss of headwater streams and freshwater wetlands and restore non-tidal waters," Palmer says.

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...

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...
