Proposals by environmentalists to declare small areas of the North Sea as no-fishing zones would not save our flagging fish stocks, suggests a new report by Newcastle University for the British Government’s Department for Environment, Food and Rural Affairs. (DEFRA).
Marine protected areas (MPAs) would need to be tens of thousands of square miles in size – at least as big as the size of Wales – and would need to be established for decades to restore levels of cod and haddock, says the report.
Moreover, creating large MPAs would be likely to intensify fishing in the waters left open for business, so further measures to reduce activity would have to be brought in.

New Project SNAPSTER: Novel luminescent materials by encapsulating phosphorescent metal clusters with organic liquid crystals
Nowadays energy conversion in lighting and optoelectronic devices requires the use of rare earth oxides.
Scientists have discovered the first synthetic material that becomes thicker - at the molecular level - as it is stretched.
Researchers led by Dr Devesh Mistry from the University of Leeds discovered a new non-porous material that has unique and inherent "auxetic" stretching...
Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg have shown through theoretical calculations and computer simulations that the force between electrons and lattice distortions in an atomically thin two-dimensional superconductor can be controlled with virtual photons. This could aid the development of new superconductors for energy-saving devices and many other technical applications.
The vacuum is not empty. It may sound like magic to laypeople but it has occupied physicists since the birth of quantum mechanics.
