False memories generated in lab mice - life - 22 March 2012. Computer modelling: Brain in a box. It wasn't quite the lynching that Henry Markram had expected.
But the barrage of sceptical comments from his fellow neuroscientists — “It's crap,” said one — definitely made the day feel like a tribunal. Officially, the Swiss Academy of Sciences meeting in Bern on 20 January was an overview of large-scale computer modelling in neuroscience. Unofficially, it was neuroscientists' first real chance to get answers about Markram's controversial proposal for the Human Brain Project (HBP) — an effort to build a supercomputer simulation that integrates everything known about the human brain, from the structures of ion channels in neural cell membranes up to mechanisms behind conscious decision-making. Computers vs. Brains. For decades computer scientists have strived to build machines that can calculate faster than the human brain and store more information.

Among the first things you notice when you step into the corner office of Harvard University professor Joanna Aizenberg are the playthings.
Behind her desk sit a sand dollar, an azure butterfly mounted in a box, a plastic stand with long fibers that erupt in color when a switch is pulled, and haphazard rows of toys. Especially numerous are the Rubik’s cubes—the classic three-by-three, of course, but also ones with four, five, six and even seven mini cubes along each edge. An eight-year-old would be in heaven. Playing with mathematical puzzles is more or less how Aizenberg, 52, spends her days. Nobody would challenge her seriousness, though.

The secret molecular life of soap bubbles (1913) Nature can be extremely devious in the way it hides its secrets.
Sometimes the most remarkable and profound insights are staring us right in the face every day in the most mundane phenomena. For instance, we have all seen the spectacular colors that can appear in soap bubbles: Image from Microscopy-uk.org.uk, by Michael Reese Much. Borrowing his lovely images until I can produce my own! These colors are produced by optical interference, as we will discuss below; the “thin film optics” that creates bright colors in soap films also results in the bright colors of oil slicks. The tiny things that rule the world. Wendy Zukerman, Asia-Pacific reporter Looking through the microscope, we can not only learn how the building blocks of life mix and interact, but also get a glimpse of the intricacy and beauty of this tiny world.
Currently showing at Questacon, Australia’s Science and Technology Centre in Canberra, The Incredible Inner Space is an exhibition of stunning microscopic images dedicated to just that. How Many Neutrons and Protons Can Get Along? Maybe 7,000. Scientists have long wondered whether there is a limit to the number of protons and neutrons that can be clustered together to form the nucleus of an atom.
A new study comes closer than ever to finding the answer by estimating the total number of nucleus variations that can exist. The periodic table of elements includes 118 known species of atoms, and each of these exists (either naturally or synthetically) in several versions with differing numbers of neutrons, giving rise to a total of about 3,000 different atomic nuclei. As technology has improved over the years, physicists have been building heavier and heavier atoms — element 117 was created only last year, and researchers are hot on the trail of 119. New projects are in the works to add and subtract neutrons to known elements to create ever more exotic variations, known as isotopes.
Space junk facts. The 5 Most Mind-Blowingly Huge Machines Built By Science. Although it seems that modern technology is all about making everything smaller, when it comes to unlocking the secrets of the universe, science is all about going big.
Really big. Right at this moment, scientists and engineers are in the process of building -- or using -- instruments that look like the engine for a Star Destroyer. Like ... #5. The next Pangaea will have pieces missing - environment - 16 September 2011. THE world's ultimate jigsaw puzzle will be missing a couple of pieces when it is next put together. A Pangaea-like supercontinent is forecast to form in 250 million years, but a new model predicts that superplumes rising from hotspots deep in the Earth's mantle will keep South America and Antarctica from re-merging with the other continents. Supercontinents form, break apart, then form again every few hundred million years.
Seeing Relativity: Trip out on a light-speed rollercoaster. Sandrine Ceurstemont, editor, New Scientist TV It's the ultimate ride for thrill-seekers: a rollercoaster hurtling down a track at near-light speed surrounded by colour changes and distortions. Now, an animation developed by physicist Michael Hush from the Australian National University in Canberra lets you see the effects described by Einstein's special theory of relativity, by creating a fictional world where the speed of light is about 5 metres per second. As the ride begins, you experience colour shifting caused by the Doppler effect.
Your surroundings also appear distorted as objects are seen at different points in time because of the finite speed of light. Due to the extreme velocity and the effect of angular compression, you start to see objects you've already passed by. Supervolcanoes Evolve Superquickly. The biggest eruptions on Earth may happen faster than volcanologists had thought. Giant blobs of magma appear underground and then pour onto the surface within centuries, suggests a new study of a California supereruption. If the work holds true for other volcanoes, it means the most powerful eruptions don’t have magma chambers beneath them for very long. So if big changes start happening, like the ground rising or new geysers spouting, volcanologists might expect an eruption sooner rather than later.
Fracking risk is exaggerated - environment - 11 January 2012. Frack away, there's no reason not to. Two of the main objections to "fracking" for shale gas have been blown out of proportion, according to British geologists. Hydraulic fracturing, or fracking, involves pumping water, sand and chemicals into methane-rich shale deposits around 2 kilometres underground to liberate natural gas. It has been accused of contaminating drinking water with methane and chemicals, and causing minor earthquakes. "We think the risk is pretty low," said Mike Stephenson, head of energy science at the British Geological Survey at a press briefing in London on Tuesday.
The idea that fracked methane leaks into drinking water was popularised by the documentary film Gasland, in which a resident of Pennsylvania sets his tap water alight (see photo).

The old phrase “united we stand, divided we fall” applies equally well to the mechanisms of attention as it does to a patriotic cause.
