The brain's garbage-disposal system may hold the key to treating Alzheimer's etc:
'In a perspective piece appearing today in the journal Science, researchers at University of Rochester Medical Center (URMC) point to a newly discovered system by which the brain removes waste as a potentially powerful new tool to treat neurological disorders like Alzheimer's disease. In fact, scientists believe that some of these conditions may arise when the system is not doing its job properly.'
Prevailing view of brain-wiring wrong?
'A series of studies conducted by Randy Bruno, PhD, and Christine Constantinople, PhD, of Columbia University's Department of Neuroscience, topples convention by showing that sensory information travels to two places at once: not only to the brain's mid-layer (where most axons lead), but also directly to its deeper layers. The study appears in the June 28, 2013, edition of the journal Science.'
Key step in protein synthesis revealed:
'Scientists at the University of California, Santa Cruz, have trapped the ribosome, a protein-building molecular machine essential to all life, in a key transitional state that has long eluded researchers. Now, for the first time, scientists can see how the ribosome performs the precise mechanical movements needed to translate genetic code into proteins without making mistakes.'
Humans caused Australia's 'angry' summer:
'Human influences through global warming are likely to have played a role in Australia's recent "angry" hot summer, the hottest in Australia's observational record, new research has found. The research led by the University of Melbourne, has shown that global warming increased mored than five-fold the chances of Australians experiencing record hot summers such as the summer of 2013.'
