Researchers have been able to demonstrate how the survivors of motor vehicle accidents have fewer such symptoms if they play Tetris in hospital within six hours of admission after also having been asked to recall their memory of the accident. The results of the study, which was conducted by researchers at Karolinska Institutet with colleagues at Oxford University and elsewhere, are published in the journal Molecular Psychiatry.

William Blake may have seen a world in a grain of sand, but for scientists at MIT the smallest of all photosynthetic bacteria holds clues to the evolution of entire ecosystems, and perhaps even the whole biosphere.

Stock traders have long used specialized trackers to decide when to buy or sell a stock, or when the market is beginning to make a sudden swing.

A type of bacteria accidentally discovered during research supported by the Engineering and Physical Sciences Research Council (EPSRC) could fundamentally re-shape efforts to cut the huge amount of electricity consumed during wastewater clean-up.

The discovery has upended a century of conventional thinking. The microorganisms - 'comammox' (complete ammonia oxidising) bacteria - can completely turn ammonia into nitrates. Traditionally, this vital step in removing nitrogen from wastewater has involved using two different microorganisms in a two-step approach: ammonia is oxidised into nitrites that are then oxidised into nitrates, which are turned into nitrogen gas and flared off harmlessly.

Using a newly-developed computer model called “CoSMoS-COAST” (Coastal Storm Modeling System – Coastal One-line Assimilated Simulation Tool) scientists predict that with limited human intervention, 31 to 67 percent of Southern California beaches may become completely eroded (up to existing coastal infrastructure or sea-cliffs) by the year 2100 under scenarios of sea-level rise of one to two meters.
