Scientists often look to nature for inspiration in the search for ways to make new materials. A new study of the clamworm, an intertidal creature, shows that it has jaws made partly of zinc, making them strong, stiff and tough –– fundamental properties by which all materials are evaluated.
The properties of the clamworm jaws are described in this week´s online publication of the Proceedings of the National Academies of Sciences (PNAS). The research began with questions by scientists at the University of California, Santa Barbara and the Argonne National Laboratory, and evolved into an international project involving scientists from Austria and Finland.
"Zinc zips together proteins in a way that hardens the material," said Galen D. Stucky, a materials chemist and professor in UCSB´s Department of Chemistry and Biochemistry. He noted that the study of how nature makes hard materials, their structure and function, may eventually yield information on how scientists can make lightweight, flexible materials ranging from more durable tires to protective coatings.

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...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
