"This happened in Hawaii," he said, "and it appears to have had little impact on the socioeconomic well-being of fishers who remained involved in the fishery since before the MPAs were in place, which is somewhat counterintuitive and makes our study interesting."
Without a separate economic analysis, said Stevenson, it's hard to say how the changing fish stocks might have affected fishing incomes. He and his co-authors—WSU Professor Brian Tissot and Bill Walsh of Hawaii's Division of Aquatic Resources—conjecture the fishers had higher yields, in part because they were steered toward underexploited or more biologically productive areas.
Fishers also benefited from rising prices for yellow tang, the most abundant and popular fish in Hawaii's aquarium trade, and price wars among island buyers working to satisfy the growing demand from coral aquarium tank owners.

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
