Accidental capture in fishing nets pushes several species to the brink
Leading marine scientists for the first time have assessed dolphin and porpoise populations around the world which are severely threatened by entanglement in fishing gear and recommended nine urgent priorities for action in a report commissioned by the World Wildlife Fund. These nine projects highlight species threatened by bycatch that will most likely benefit from immediate action and will continue to languish without intervention.
The list of dolphins and porpoises that could recover if changes to fishing methods and other conservation efforts are made includes harbor porpoises in the Black Sea, where thousands of porpoises are killed each year; Atlantic humpback dolphins off the coast of west Africa; and franciscana dolphins in South America. Most of the species on the list are threatened by the widespread use of one type of fishing gear – gillnets. These nets are difficult for dolphins and porpoises to spot visually or detect with their sonar, so they may become tangled in the netting or in the ropes attached to the nets.

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...
