Analysis Of Neurotech Industry - News Markets. Give geo- and genetic engineering a fair trial - 07 September 2011. Frontier science must not be feared, but cautiously embraced IN A city in eastern Brazil, scientists are preparing to release millions of genetically modified mosquitoes into the wild.
If the trial works, the people of Juazeiro will have GM technology to thank for keeping them safe from dengue fever (see "Swarm troopers: Mutant armies waging war in the wild"). False memories generated in lab mice - life - 22 March 2012. In the 1940s, neurosurgeon Wilder Penfield found his patients would recall seemingly random information – the smell of cookies for instance – when he stimulated different brain areas with electric shocks.
Two studies have now found evidence to support the memory storage theory that Penfield stumbled across. The research, in mice, even demonstrates that it is possible to manipulate brain cells to create false memories. Mark Mayford of the Scripps Research Institute in San Diego, California, and colleagues genetically engineered mice so that neurons that fired would fire again when the brain was injected with a drug. 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.
Markram, a South-African-born brain electrophysiologist who joined the Swiss Federal Institute of Technology in Lausanne (EPFL) a decade ago, may soon see his ambition fulfilled. Computers vs. Brains. For decades computer scientists have strived to build machines that can calculate faster than the human brain and store more information.
The contraptions have won. The world’s most powerful supercomputer, the K from Fujitsu, computes four times faster and holds 10 times as much data. Technology Is One Path Toward Sustainability. A case for modernization as the road to salvation by Michael Shellenberger and Ted Nordhaus Illustration: Thom Lang / Corbis SOMETIME AROUND 2014, Italy will complete construction of seventy-eight mobile floodgates aimed at protecting Venice’s three inlets from the rising tides of the Adriatic Sea.
The massive doors—twenty meters by thirty meters, and five meters thick—will, most of the time, lie flat on the sandy seabed between the lagoon and the sea. How Deep Is the Ocean?

The Brittle Star's Apprentice. 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! 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. 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. As the rollercoaster passes over a series of bumps, colour-shifting and distortion increase and decrease. Supervolcanoes Evolve Superquickly.
