An ambitious plan is under way in the ecological community to agree a set of standards for ecologically successful river restoration. The plan is being led by the British Ecological Societys Journal of Applied Ecology, which this month is publishing a special profile on river restoration. Opening the debate is a paper by 22 leading US river ecologists proposing five criteria for ecologically successful river restoration. Their aim is to arrive at an agreed set of standards which would eventually be endorsed by the United Nations Environment Programme.
Although billions of dollars are spent on river restoration projects worldwide, little agreement exists on how their success is measured. According to lead author Dr Margaret Palmer of the University of Maryland: “Given the rapid rate of global degradation of fresh waters, and the fact that river and stream restoration has become a booming enterprise, it is time to agree on what constitutes successful river and stream restoration.”
Palmer and her colleagues say that the success of river restoration should be judged according to five criteria: a guiding image; improving ecosystems; increasing resilience; doing no lasting harm; and completing an ecological assessment.

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...
Breakthrough provides a new concept of the design of molecular motors, sensors and electricity generators at nanoscale

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...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
