High levels of carbon dioxide in the atmosphere may have less of an impact on the rate of global warming than previously feared, a new study suggests. Associate Professor Schmittner notes that many previous studies only looked at periods spanning from 1850 to today, thus not taking into account a fully integrated palaeoclimate data on a global scale. The authors of the study stress that global warming is real and that increases in atmospheric CO2, which has doubled from pre-industrial standards, will have multiple serious impacts. But more severe estimates that predict temperatures could rise up to an average of 10 degrees Celsius are unlikely, the researchers report in the journal Science. The new study suggests temperatures will rise on average 2.3 degrees under the same conditions. Scientists have long struggled to quantify climate sensitivity, or how the Earth will respond to projected increases in carbon dioxide, the main greenhouse gas. READ MORE
A new study suggests that Autism starts in the womb, researchers have found a remarkable 67 per cent increase in the total number of brain cells in the prefrontal cortex of new born babies with ASD. Children with autism appear to have too many cells in a key area of the brain needed for communication and emotional development, say US researchers. Their findings help explain why young children with autism often develop brains that are larger or heavier than normal. Dr Eric Courchesne says the finding of excess brain cells in the prefrontal cortex explains brain overgrowth in autism, and hints at why brain function in this area is disrupted. Courchesne, of the University of California San Diego Autism Center of Excellence, and colleagues, have also found dozens of genes that may raise the risk of autism. But genetic causes only explain 10 per cent to 20 per cent of cases, and recent studies have pointed to environmental factors, possibly in the womb, as a potential trigger. The team found excess brain cells in each child with autism they studied, says Courchesne. And the brains of the autistic children also weighed more than those of typically developing children of the same age.
Preface to a Forethought: 2007 John-Dylan Haynes discovers pre-forethought; Each and every minute of every day our brains are seemingly forced to plan thousands of mundane actions that allow our lives to seamlessly flow. How and where the brain stores these Intentions has been apparently been revealed by John-Dylan Haynes. For the first time researchers were able to read participants’ intentions from their brain activity. Concluding that the brain makes a decision approximately 1-7 seconds before consciousness is aware of the decision! This was made possible by a new combination of functional magnetic resonance imaging – MRI - and a set of sophisticated computer algorithms. Haynes and similar thinking scientists believe that what Philosophy calls Free Will, are in fact pre-mapped – Intentions - critical decisions made prior to all conscious and non conscious decisions. Free Will: Science has always had a problem with Free Will , it implies no cause and effect, science relies entirely on empirical data. Free Will, defies any quantification, it flies in the face of an organised, rational, systemic view on thought processing and creation. The work of Haynes and his colleagues went far beyond simply confirming previous theories of the lack of Free Will. The study revealed fundamental principles about the way the brain stores Intentions.
“The experiments show that intentions are not encoded in single neurons but in a whole spatial pattern of brain activity” says Haynes.
They furthermore reveal that different regions of the prefrontal cortex perform different operations. Regions towards the front of the brain store the intention until it is executed, whereas regions further back take over when subjects become active and start doing the calculation.

Outwardly it may seem that two vocations couldn’t be further apart. Throughout my life I’ve known a heap of really smart people, people with really high IQ’s that excelled in school, that went on to become intellectually impressive. I’ve also met and worked with a lot of extremely successful entrepreneurs. Entrepreneurs worth 7, 8 and even 9 figures. Intriguingly, the two groups are pretty much mutually exclusive. With one exception, SCIENTISTS. Why? :: Read the full article »»»»
