    In pictures, Obama appears to have a long scar which goes up the side of his head and over his crown. Some conspiracy theorists claim they are scars that you would see on someone who has had brain surgery. But without medical records (along with his school records and birth certificate) no one seems to be able to provide an answer as to the cause of the mystery scars. Ben Hart, a blogger for Escape The Tyranny a website which presents itself as a Social Network & Forum For Conservatives, said: 'Obama's almost done with his first term, and we...

    A 2,500-year-old human skull uncovered in England was less of a surprise than what was in it: the brain. The discovery of the yellowish, crinkly, shrunken brain prompted questions about how such a fragile organ could have survived so long and how frequently this strange type of preservation occurs. Except for the brain, all of the skull's soft tissue was gone when the skull was pulled from a muddy Iron Age pit where the University of York was planning to expand its Heslington East campus. [Britain's Oldest Brain Found] "It was just amazing to think that a brain of someone...

    Even long after it is formed, a memory in rats can be enhanced or erased by increasing or decreasing the activity of a brain enzyme, say researchers supported, in part, by the National Institutes of Health. "Our study is the first to demonstrate that, in the context of a functioning brain in a behaving animal, a single molecule, PKMzeta, is both necessary and sufficient for maintaining long-term memory," explained Todd Sacktor, of the SUNY Downstate Medical Center, New York City, a grantee of the NIH's National Institute of Mental Health.

    GUMC neuroscientists say their novel gene therapy shows that clearing toxic proteins inside brain cells prevents plaque formation outside neuronsWashington, D.C. – Gene therapy that boosts the ability of brain cells to gobble up toxic proteins prevents development of Alzheimer's disease in mice that are predestined to develop it, report researchers at Georgetown University Medical Center. They say the treatment – which is given just once - could potentially do the same in people at the beginning stages of the disease. The study, published online in Human Molecular Genetics, demonstrates that giving brain cells extra parkin genes promotes efficient and...
  • Child brain scans to pick out future criminals

    Telegraph ^ | 2/21/11 | Richard Alleyne
    The seeds of criminal and anti-social behaviour can be found in children as young as three, scientists have claimed. More researchers believe that violent tendencies have a biological basis and that tests and brain imaging can pick them up in children. They argue that, by predicting which children have the potential to be trouble, treatments could be introduced to keep them on the straight and narrow. If the tests are accurate enough then a form of screening could be introduced in the same way we test for some diseases.

    Former Chicago Bears safety Dave Duerson died of a self-inflicted gunshot wound to the chest, a source with knowledge of the situation told the Tribune. His death has been ruled a suicide, but the Miami-Dade police department has yet to make the information public. Foul play was ruled out, in part because no one but Duerson was seen entering his condominium for two days before the shooting.

    If you're a conservative, it might be your brain's fault. So says British scientists who scanned the brains of two members of the British Parliament and about 90 students. Richard Alleyne, Science Correspondent for the UK Telegraph, reported Wednesday that those with conservative views have larger amygdalas, the area of the brain associated with anxiety and fear. They also have a smaller anterior cingulate, an area at the front of the brain associated with courage and optimism. Prof Geraint Rees, of the University College London and head researcher for the study, told the Telegraph: "We were very surprised to find...

    The human brain is truly awesome.A typical, healthy one houses some 200 billion nerve cells, which are connected to one another via hundreds of trillions of synapses. Each synapse functions like a microprocessor, and tens of thousands of them can connect a single neuron to other nerve cells. In the cerebral cortex alone, there are roughly 125 trillion synapses, which is about how many stars fill 1,500 Milky Way galaxies. This is a visual reconstruction from array-tomography data of synapses in the mouse somatosensory cortex, which is responsive to whisker stimulation.(Credit: Stephen Smith/Stanford) These synapses are, of course, so tiny...

    How do we explain the current sorry spectacle of a highly intelligent president who repeatedly makes bad choices and decisions? Make no mistake about it – President Obama has done just that. Ever pause and wonder how ostensibly perspicacious individuals can show remarkable errors in judgment? History is filled with people like this, proving repeatedly intelligence is no guarantee of good judgment and decision-making. Why? In the 1980s, American aerodynamicists faced a conundrum: How did the USSR, using comparatively rudimentary computers and without CAD/CAM, nonetheless closely match America's best fighter designs? The answer, not immediately obvious, was that Soviet programmers...

    CHAMPAIGN, lll. – Researchers have found an association between physical fitness and the brain in 9- and 10-year-old children: Those who are more fit tend to have a bigger hippocampus and perform better on a test of memory than their less-fit peers. The new study, which used magnetic resonance imaging to measure the relative size of specific structures in the brains of 49 child subjects, appears in the journal Brain Research. “This is the first study I know of that has used MRI measures to look at differences in brain between kids who are fit and kids who aren’t fit,”...

    Israeli scientists believe they have identified why Arabic is particularly hard to learn to read. The University of Haifa team say people use both sides of their brain when they begin reading a language - but when learning Arabic this is wasting effort. The detail of Arabic characters means students should use only the left side of their brain because that side is better at distinguishing detail. (Snip) Both young children and adults call on both hemispheres to help them learn a new task. And using both hemispheres is the right thing to do when reading English or Hebrew -

    FINDING it difficult to revise for an exam? Help could be on its way in the form of the first non-invasive way of stimulating the brain that can boost visual memory. The technique uses transcranial direct current stimulation (tDCS), in which weak electrical currents are applied to the scalp using electrodes. The method can temporarily increase or decrease activity in a specific brain region and has already been shown to boost verbal and motor skills in volunteers. Richard Chi, a PhD student at the Centre for the Mind, University of Sydney, and colleagues wanted to follow up on previous research...

    The researchers suggest that for religious people, thinking about God may provide a way of ordering the world and explaining apparently random events and thus reduce their feelings of distress. In contrast, for atheists, thoughts of God may contradict the meaning systems they embrace and thus cause them more distress.

    THE French have elevated it to an art form, and even the British have got better at it - but chimps can't cook at all. According to one controversial evolutionary theory, early humans developed a taste for cooked food around 2 million years ago, and this set in motion a series of changes that made us utterly different from any other animal. Now the proponents of the cooked-food hypothesis are presenting fresh evidence in support of the idea - and it all comes down to how you chew. The theory, championed by Richard Wrangham at Harvard University, has divided palaeoanthropologists....

    The amount of cholesterol circulating in the bloodstream is partly regulated by the brain, a study in mice suggests. It counters assumptions that levels are solely controlled by what we eat and by cholesterol production in the liver. The US study in Nature Neuroscience found that a hunger hormone in the brain acts as the "remote control" for cholesterol travelling round the body.Too much cholesterol causes hardened fatty arteries, raising the risk of a heart attack. The research carried out by a US team at the University of Cincinnati found that increased levels of the hunger hormone ghrelin in mice...

The “click” of comprehension triggers a biochemical cascade that rewards the brain with a shot of natural opium-like substances, said Irving Biederman of the University of Southern California. He presents his theory in an invited article in the latest issue...

Ellen Edgerly, 51, an advocate with the state's Brain Injury Association, was sitting in the middle of the room, a lone voice in a sea of leather and wild beards, when a lawmaker asked if anyone supported the change. "She stood up, passed all of these tough guys, and testified about brain injury and what it means," says Steven Wade, the association's executive director. "It took...
