DARPA Program Seeks to Use Brain Implants to Control Mental Illness Researcher Jose Carmena has worked for years training macaque monkeys to move computer cursors and robotic limbs with their minds. He does so by implanting electrodes into their brains to monitor neural activity. Now, as part of a sweeping $70 million program funded by the U.S. military, Carmena has a new goal: to use brain implants to read, and then control, the emotions of mentally ill people. This week the Defense Advanced Research Projects Agency, or DARPA, awarded two large contracts to Massachusetts General Hospital and the University of California, San Francisco, to create electrical brain implants capable of treating seven psychiatric conditions, including addiction, depression, and borderline personality disorder. The project builds on expanding knowledge about how the brain works; the development of microlectronic systems that can fit in the body; and substantial evidence that thoughts and actions can be altered with well-placed electrical impulses to the brain.
Cyborgs – scientists create biological tissue with embedded wiring Under its human skin, James Cameron’s Terminator was a fully-armored cyborg built out of a strong, easy-to-spot hyperalloy combat chassis – but judging from recent developments, it looks like Philip K. Dick and his hard-to-recognize replicants actually got it right. In a collaboration between Harvard, MIT and Boston Children's Hospital, researchers have figured out how to grow three-dimensional samples of artificial tissue that are very intimately embedded within nanometer-scale electronics, to such an extent that it is hard to tell where one ends and the other begins.
Minute machines dive inside a living creature for first time — RT News Published time: January 23, 2015 16:10 Reuters / Phil Noble Researchers at the University of California have managed to implant acid-powered, self-destructing micromotors inside a living animal for the first time. It's hoped the tiny devices could help tackle maladies such as peptic ulcers in the future. The tiny machines just 20 micrometers long and roughly a human hair's width, managed to deliver nano-particles to the stomach of a mouse without any side effects. The self-propelled devices, made of polymer tubes and coated in zinc, self-destruct without leaving any traces of harmful chemicals. Functional 3D Brain Tissue Successfully Grown From Stem Cells The ultimate goal of stem cell research is to create functional replica tissues and organs for use as replacements in times of injury or disease, or for use in the development of drugs and other therapeutic techniques. Getting tissues to grow in the lab in three dimensions has been challenging across the board, but this is especially problematic for structures in the nervous system. Beyond getting the neurons to grow at all, they must be connected in a very particular manner in order to function. A major step forward has been taken on this front by a team from RIKEN Center for Developmental Biology in Japan, who state in Cell Reports that they have successfully grown 3D functional brain tissue that has even grown with proper patterning. The brain tissues were grown from human embryonic stem cells, and growth factors were added in series throughout development.
Scientists discover whole new state of matter Most people are familiar with some of the common states of matter: solids, liquids and gases. Scientists also recognize a fourth state of matter — plasma — that is commonly observable here on Earth, as well as a host of other states that can only be created in the lab, such as Bose–Einstein condensates and neutron-degenerate matter. Jahn-Teller metals can now be added to this list, a state which appears to have the properties of an insulator, superconductor, metal and magnet all wrapped into one. It's the material's superconductivity which might be the most interesting trait, however. It has the potential to achieve superconductivity at a relatively high critical temperature ("high" as in -135 degrees Celsius as opposed to the sub -243.2 degrees Celsius required by many ordinary metallic superconductors), which is significant for the science of superconductivity.

Scientists learn to selectively erase and restore memories in brain Published time: June 04, 2014 23:41 Edited time: June 06, 2014 23:19 Reuters / STR Wiping out memories at a press of a button – just like with a ‘neuralizer’ from the Men in Black movie – may soon become a reality. Researchers have managed to erase and then restore lost memory in genetically modified rats with a flash of light. The study by researchers from University of California in San Diego, published in Nature journal , is the first cause-and-effect evidence that strengthening or weakening connections between neurons in the brain can influence particular memories. “We can form a memory, erase that memory and we can reactivate it, at will, by applying a stimulus that selectively strengthens or weakens synaptic connections,” study senior researcher Dr.
Tiny Scallop-Like Robots Designed To Deliver Drugs Through The Bloodstream To Treat Diseases - Futurism Synopsis Researchers in Germany have developed a "scallop-inspired" tiny robot small enough to travel through the bloodstream, and it doesn't require an engine or batteries Summary The idea for the new robot was inspired by the scallop, which moves around by opening and closing a pair of shells. The robot moves through a non-Newtonian fluid by performing what looks like horizontal jumping jacksThe tiny bots can be printed on a 3D printer, and many of them could be directed at once with a single magnetThe team doesn’t have any particular applications in mind for their robots, but it’s clear that they could be used to send medication to single spot, such as to kill tumors
IBM Develops a New Chip That Functions Like a Brain - NYTimes.com Photo Inspired by the architecture of the brain, scientists have developed a new kind of computer chip that uses no more power than a hearing aid and may eventually excel at calculations that stump today’s supercomputers. The chip, or processor, is named TrueNorth and was developed by researchers at IBM and detailed in an article published on Thursday in the journal Science. Worm ‘Brain’ Uploaded Into Lego Robot Worm ‘Brain’ Uploaded Into Lego Robot Can a digitally simulated brain on a computer perform tasks just like the real thing? For simple commands, the answer, it would seem, is yes it can. Cover Charge: New Spray-On Battery Could Convert Any Object into an Electricity Storage Device Perhaps someday you'll need to go to the store because you ran out of cathode paint. A team of researchers has just announced a new paint-on battery design. The technique could change the way batteries are produced and eliminate restrictions on the surfaces used for energy storage. The paint-on battery, like all lithium ion batteries, consists of five layers: a positive current collector, a cathode that attracts positively charged ions, an ion-conducting separator, an anode to attract negative ions, and a negative current collector. For each layer, the challenge was to find a way to mix the electrically conductive material with various polymers to create a paint that could be sprayed onto surfaces. Neelam Singh, a member of the team of materials scientists and chemists from Rice University in Houston and Catholic University of Louvain in Belgium and lead author of the paper, says, "It was really exciting to find out.
Eviction notice for DAPL protest camp should be viewed through the lens of military tactics - Boulder Weekly Joel Dyer On Friday, Nov. 25, Colonel John Henderson, district commander of the U.S. Army Corps of Engineers, sent an eviction notice to several thousand people who are currently living in the Oceti Sakowin Camp just north of the Cannonball River in North Dakota. The protesters, who established the camp and call themselves “water protectors,” are living in the camp as part of their efforts to stop the completion of the Dakota Access Pipeline (DAPL) as well as to strengthen the Greater Sioux Nation’s ownership claims on the lands north of the river as granted under the 1851 Treaty of Fort Laramie. Ownership of the 1851 Treaty lands under the Oceti Sakowin Camp — which currently covers approximately 137 acres — is also claimed by the federal government via the U.S. Army Corps of Engineers.
