Comment: Small fizzle, but solar cycle 24 is interesting. (Score 1) 131

It's just an X2.2 R3 "event". Which means, in worst case: "HF Radio: Wide area blackout of HF radio communication, loss of radio contact for about an hour on sunlit side of Earth." "Navigation: Low-frequency navigation signals degraded for about an hour." In 2003 there was a solar flare at X28++ ... don't think anyone remembers that. It might however be somewhat interesting for people following cycle 24, with all the sunspot magnetic fields progressively getting weaker and all...

+ - Protein deficiency behind 25% of schizophrenia->

Submitted by kcscarp
kcscarp writes: The Age reports that scientists from the Mental Research Health Institute in Parkville, Australia have discovered that a form of schizophrenia is linked to a lack of certain proteins in the brain's lining. The discovery is being compared to the discovery that type 1 and type 2 diabetes were separate diseases requiring different treatments. The group's research shows that 25 per cent of people who have schizophrenia have lost 80 per cent of a protein in their brain known as muscarinic M1 receptor. The discovery was made by examining the brain tissue of deceased patients. The next phase of the research will involve using neuro-imaging to identify living people with this form of schizophrenia.

+ - Virtual robots fooled by visual illusions

Roland Piquepaille writes: "Researchers at University College London (UCL) have written a computer program using neural networks which are duped by optical illusions the same way as we do. Their virtual robots, which were trained to 'see' like us, could help to understand why we fall for optical illusions. This might also be important for robot vision. If robots are trained to 'see' like us, they will act like us — and make mistakes. Very interesting... But read more for additional references and one of the visual illusions featured on the Web site of the lead researcher for this project."
