Navy: Grow Sailors’ Brains With iPhone App | Danger Room It’s not that the Navy is calling you stupid. The seafaring service just wants to actually see your brain grow. High on the Navy’s just-released wish list for designs from small businesses is a “brain-fitness training program” that sailors can use to sharpen their cognitive skills. Think of it like a souped-up adult education app. Any business that wants the Navy’s cash must demonstrate that its learning program will actually change sailors’ brains. What “growth” in this context actually means is a faster brain, where synapses fire electrical impulses more rapidly in response to stimuli. But it’s far from clear how it would work. Helping troops recover from traumatic brain injury, the signature wound of the Iraq and Afghanistan wars, is only one application of the envisioned program. And if anything, the Navy’s late to the mind-manipulation party. And the futurists at Darpa fund a project to manipulate troops’ brains remotely through microscopic devices placed in their helmets.
Neuroscience of free will Neuroscience of free will is the part of neurophilosophy that studies the interconnections between free will and neuroscience. As it has become possible to study the living brain, researchers have begun to watch decision making processes at work. Findings could carry implications for our sense of agency and for moral responsibility and the role of consciousness in general. Relevant findings include the pioneering study by Benjamin Libet and its subsequent redesigns; these studies were able to detect activity related to a decision to move, and the activity appears to begin briefly before people become conscious of it. Other studies try to predict activity before overt action occurs. Taken together, these various findings show that at least some actions - like moving a finger - are initiated unconsciously at first, and enter consciousness afterward. A monk meditates.

Blue Brain Project Scientists extract images directly from brain ::: Pink Tentacle Researchers from Japan's ATR Computational Neuroscience Laboratories have developed new brain analysis technology that can reconstruct the images inside a person's mind and display them on a computer monitor, it was announced on December 11. According to the researchers, further development of the technology may soon make it possible to view other people's dreams while they sleep. The scientists were able to reconstruct various images viewed by a person by analyzing changes in their cerebral blood flow. Using a functional magnetic resonance imaging (fMRI) machine, the researchers first mapped the blood flow changes that occurred in the cerebral visual cortex as subjects viewed various images held in front of their eyes. Then, when the test subjects were shown a completely new set of images, such as the letters N-E-U-R-O-N, the system was able to reconstruct and display what the test subjects were viewing based solely on their brain activity.

Controlling Computers with Your Mind November 8, 2010 Scientists used a brain-computer interface to show how the activity of just a few brain cells can control the display of pictures on a computer screen. The finding sheds light on how single brain cells contribute to attention and conscious thought. Patients were asked to focus on 1 of 2 superimposed images, here of Michael Jackson and Marilyn Monroe. Researchers have been making great progress in developing brain-computer interfaces—devices that let a person's thoughts guide the actions of a computer. This technology can potentially help paralysis patients control prosthetic limbs and communicate. A team of scientists led by Dr. The scientists recruited 12 patients with drug-resistant epilepsy. In a previous study, the researchers found that individual brain cells respond more strongly to certain images than to others. For this study, the scientists first identified neurons in each person that responded selectively to 4 different images.
Nerve-Electronic Hybrid Could Meld Mind and Machine | Wired Science Nerve-cell tendrils readily thread their way through tiny semiconductor tubes, researchers find, forming a crisscrossed network like vines twining toward the sun. The discovery that offshoots from nascent mouse nerve cells explore the specially designed tubes could lead to tricks for studying nervous system diseases or testing the effects of potential drugs. Such a system may even bring researchers closer to brain-computer interfaces that seamlessly integrate artificial limbs or other prosthetic devices. “This is quite innovative and interesting,” says nanomaterials expert Nicholas Kotov of the University of Michigan in Ann Arbor. “There is a great need for interfaces between electronic and neuronal tissues.” To lay the groundwork for a nerve-electronic hybrid, graduate student Minrui Yu of the University of Wisconsin–Madison and his colleagues created tubes of layered silicon and germanium, materials that could insulate electric signals sent by a nerve cell.

New solar fuel device that ”mimics plant life” Scientists have unveiled a prototype solar device that mimics plant life, turning the Sun’s energy into fuel. The device uses the Sun’s rays and a metal oxide called ceria to break down carbon dioxide or water into fuels, which can be stored and transported. The prototype, which has been devised by researchers in the US and Switzerland, uses a quartz window and cavity to concentrate sunlight into a cylinder lined with cerium oxide, also known as ceria. If as in the prototype, carbon dioxide and/or water are pumped into the vessel, the ceria will rapidly strip the oxygen from them as it cools, creating hydrogen and/or carbon monoxide. Hydrogen produced could be used to fuel hydrogen fuel cells in cars, for example, while a combination of hydrogen and carbon monoxide can be used to create “syngas” for fuel. It is this harnessing of ceria’s properties in the solar reactor, which represents the major breakthrough, said the inventors of the device. “It’s very much tied to policy.

U.S. Teenager eats live goldfish while friends record the act untitled by J. Curt Stager This article is an adaptation of the introduction to J. Curt Stager’s Deep Future: The Next 100,000 Years of Life on Earth (Thomas Dunne Books, an imprint of St. Martin’s Press), published here courtesy of the author and publisher. This excerpt appears in two parts. In the past, seemingly intractable debates over environmental issues have sometimes been resolved with the aid of long-term historical perspectives. Although it's a rather eclectic discipline that straddles the fields of geology and biology, my chosen profession of paleoecology is well known among scientists for its ability to harness truly long-term thinking in order to place current environmental issues into their most meaningful contexts, showing us where we've been, how we got here, and where we're likely to be headed next. Until now, our collective view of future warming has typically ended at 2100 AD, as if it were the edge of a world beyond which we dare not sail. But all is not doom and gloom.
(3) Given our current technology and with the proper training, would it be possible for someone to become Batman News of Future: Fooling Arnold Made a Clean Sweep in Saturday Ratings January 8, 2035 - With a first prize of seven million US dollar and the intriguing plot of trying to fool or outsmart Arnold, the most advanced artificial intelligence in public use, the much hyped live show “Fooling Arnold” became the people’s choice this Saturday. If you haven’t seen the show yet, it takes place in an ancient castle where eight people should solve different tasks while constantly conversing with Arnold. The contestants should try to convince or fool Arnold to believe certain facts about them. The four worst liars spotted by Arnold from each show have to leave and is replaced by the four best lying-spotting viewers who are flown in to the show the following week, giving their best shot to fool Arnold. The extraordinary prize amount is sponsored by the consortium of companies behind the Arnold technology. But they are playing a somewhat dangerous game putting more than the money on the line.
