It takes a supercomputer to mimic a mouse brain.

US researchers have simulated half a virtual mouse brain on a supercomputer. The scientists ran a "cortical simulator" that was as big and as complex as half of a mouse brain on the BlueGene L supercomputer.In other smaller simulations the researchers say they have seen characteristics of thought patterns observed in real mouse brains. Now the team is tuning the simulation to make it run faster and to make it more like a real mouse brain.Brain tissue presents a huge problem for simulation because of its complexity and the sheer number of potential interactions betweenthe elements involved. The three researchers, James Frye, Rajagopal Ananthanarayanan, and Dharmendra S Modha, laid out how they went about it in a very short research note entitled "Towards Real-Time, Mouse-Scale Cortical Simulations". Half a real mouse brain is thought to have about eight million neurons each one of which can have up to 8,000 synapses, or connections, with other nerve fibres. Modelling such a system, the trio wrote, puts "tremendous constraints on computation, communication and memory capacity of any computing platform". The team, from the IBM Almaden Research Lab and the University of Nevada, ran the simulation on a BlueGene L supercomputer that had 4,096 processors, each one of which used 256MB of memory. Using this machine theresearchers created half a virtual mouse brain that had 8,000 neurons that had up to 6,300 synapses. The vast complexity of the simulation meant that it was only run for ten seconds at a speed ten times slower than real life - the equivalent of one second in a real mouse brain. On other smaller simulations the researchers said they had seen "biologically consistent dynamical properties" emerge as nerve impulses flowed through the virtual cortex. In these other tests the team saw the groups of neurons form spontaneously into groups.

They also saw nerves in the simulated synapses firing in a ways similar to the staggered, co-ordinated patterns seen in nature. The researchers say that although the simulation shared some similarities with a mouse's mental make-up in terms of nerves andconnection......

Scientists: earth barely supports life

If earth had been slightly smaller and less massive, life might never have gained a foothold. They key to life on Earth as we know it, scientists figure, is plate tectonics the forces that move continents and build mountains. And the more massive a world is, the thinner its plates are. Thinner plates are weaker and more easily moved and so able to support the kinds of crucial planet-shaping plate tectonics experienced on this planet over the billions of years that life evolved from simple one-...

Last ice age happened in less than a year

The last ice age 13,000 years ago took hold in just one year, more than ten times quicker than previously believed, scientists have warned. Rather than a gradual cooling over a decade, the ice age plunged Europe into the deep freeze, German Research Centre for Geosciences at Potsdam said. Cold, stormy conditions causedby an abrupt shift in atmospheric circulation froze the continent almost instantly during the Younger Dryas less than 13,000 years ago a very recent period on a geological scale....

Magnets may make the brain grow stronger

Could magnets make the mind grow stronger? In mice at least, stimulating the brain with a magnetic coil appears to promote the growth of new neurons in areas associated with learning and memory. If the effect is confirmed in humans, it might open up new ways of treating age-related memory decline and diseases like Alzheimer's.Transcranial magnetic stimulation (TMS) has been used experimentally to treat a range of brain disorders, including depression and schizophrenia, and torehabilitate peo...

Scientists claim dark matter discovery

Dark matter is thought to account for three-quarters of the matter in the universe but to date has never been directly observed. Now scientists are claiming a breakthrough discovery ofactual dark matter in a mine half a mile underground."For 80 years, it haseluded the finest minds in science. . But tonight it appeared that the hunt may be over for dark matter, the mysterious and invisible substance that accounts for three-quart...

Japan to put humanoid robot on moon by 2015 ?

A new proposal by several Japanese companies is aiming to put an android on the moon within just 5 years.The robot named Maido-kun is hoping to hitch a ride on a planned mission to the moon by the Japanese space agency, once there it will walk around on the surface and draw the Japanese flag on the ground in the dust. A humanoidrobot could be walking on the moon and drawing the Japanese flag on its surface by 2015, according to a plan proposed by a groupof Japanese companies. . Exp...

The higher you are, the faster you age

Extremely precise timepieces have been used to prove that you age faster the higher off the ground you are.New research has shown that if you lived your life on the second floor of a building you would age faster by 900 billionths of a second. Its not much, but for the first time scientists have been able to actually demonstrate that there is a difference. Researchers havedemonstrated one of Einstein"s theories of relativity - that the further away from the Earth you are, the faster tim...

Dmitry Itskov plans immortality by 2045

The Russian mogul has set in motion a plan to achieve cybernetic immortality within 33 years.Known as the "2045 initiative", Itskov and his team have laid out an ambitious time line that would see them transplant a brain in to an artificial body by 2020, the creation of an artificial brain by 2030 and the creation of a holographic body by 2040. The project"s ultimate goal, tentatively scheduled for 2045, would be totransfer a human mind in to a holographic body.Itskov recently wrote a...
