Digital Tattoo Gets Under Your Skin to Monitor Blood Bioengineering doctoral student Kate Balaconis shines the iPhone reader against her tattooless arm. Maybe tattoos aren’t just for Harley riders or rebellious teens after all. In a few years, diabetics might get inked up with digital tats that communicate with an iPhone to monitor their blood. Alzheimer's breakthrough hailed as 'turning point' 10 October 2013Last updated at 08:56 GMT By James Gallagher Health and science reporter, BBC News Professor Giovanna Mallucci says the hope is to arrest the process of brain cell death The discovery of the first chemical to prevent the death of brain tissue in a neurodegenerative disease has been hailed as the "turning point" in the fight against Alzheimer's disease. More work is needed to develop a drug that could be taken by patients. But scientists say a resulting medicine could treat Alzheimer's, Parkinson's, Huntington's and other diseases. In tests on mice, the Medical Research Council showed all brain cell death from prion disease could be prevented.
3D Printing Droplet Networks Peter Rothman Oxford University scientists have demonstrated a custom-built programmable 3D printer which can create materials with several of the properties of living tissues. The new type of material consists of thousands of connected water droplets, encapsulated within lipid films, which can perform some of the functions of the cells inside our bodies. These printed 'droplet networks' could be the building blocks of a new kind of technology for delivering drugs and potentially one day replacing or interfacing with damaged human tissues. Because these droplet networks are entirely synthetic, have no genome and do not replicate, they avoid some of the problems associated with other approaches to creating artificial tissues – such as those that use stem cells. The team report their findings in this week's Science:
Electronic tattoo An ultra-thin electronic device that attaches to the skin like a stick on tattoo can measure electrical activity of the human body like heart, brain waves and other vital signs without the bulky electrodes used in current monitoring. process These tattoos are similar to those in children's fake tattoos. It usually starts out on a sheet of plastic, is then applied to the skin and rubbed on from outside the plastic, then the plastic is peeled away, leaving only a very thin, rubber patch that has a layer of flexible silicon wires.
Dopamine regulates the motivation to act Printer friendly version Share 10 January 2013 Asociación RUVID Bionic humans are about to get an upgrade, thanks to monkey cyborgs A - Given that decoding the human genome went from being something incredibly complex that would cost millions and take years to do, to something that can be done via mail-order and a couple hundred bucks in just a couple of decades, I doubt that it'll be centuries before we understand the human brain. Probably more like a few decades. B - We needn't develop directly analogous bionics to be a significant threat to what exists in nature (and ourselves). Consider an autonomous supply chain that was able to recreate all of its components without human intervention, perfect generational copying, as well as guided evolution of new versions. In nature, the network effect is really weak and evolution is random, but in technology, a network of individuals can aggregate and guide all participants, and guide evolution significantly more efficiently. First of all, we don't need to understand the brain perfectly to make good bionics.
Human enhancement An electrically powered exoskeleton suit in development as of 2010 by Tsukuba University of Japan. Human enhancement is "any attempt to temporarily or permanently overcome the current limitations of the human body through natural or artificial means. It is the use of technological means to select or alter human characteristics and capacities, whether or not the alteration results in characteristics and capacities that lie beyond the existing human range."  Brains flush toxic waste in sleep, including Alzheimer’s-linked protein, study of mice finds Scientists say this nightly self-clean by the brain provides a compelling biological reason for the restorative power of sleep. “Sleep puts the brain in another state where we clean out all the byproducts of activity during the daytime,” said study author and University of Rochester neurosurgeon Maiken Nedergaard. Those byproducts include beta-amyloid protein, clumps of which form plaques found in the brains of Alzheimer’s patients. Staying up all night could prevent the brain from getting rid of these toxins as efficiently, and explain why sleep deprivation has such strong and immediate consequences.
Personal Home Pages and the Construction of Identities on the Web Introduction It has been contended by media theorists such as Joshua Meyrowitz (1985) that the adoption of new media seems to involve a shifting or blurring of the boundaries of public and private. Without adopting the stance of hard technological determinism (Chandler 1995b; 1996), we may perceive such a shift in the new genre of the personal home page on the World-Wide Web. Whilst the fundamental technical difference between the medium of speech and that of writing is that writing is automatically recorded, web pages introduce another key feature: what is written on a web page (and stored on a web-server) is automatically published on a global scale.
Cyborg A cyborg (short for "cybernetic organism") is a theoretical or fictional being with both organic and biomechatronic parts. The term was coined in 1960 by Manfred Clynes and Nathan S. Kline. D. Inside Paul Allen's Plan to Reverse-Engineer the Human Brain - Wired Science In 2003, Microsoft cofounder Paul Allen spent $100 million to build the Allen Institute for Brain Science in Seattle. With laser-equipped microscopes and custom brain-slicers, the institute has mapped the brains of mice, monkeys, and humans, showing which genes are turned on—and where—to better understand vision, memory, autism, and other neural phenomena. Last year Allen ponied up another $300 million to aim the institute at a narrower but more ambitious goal: a complete understanding of how the mouse brain interprets visual information. To succeed, they’ll have to go beyond static gene maps and learn how to watch a living brain in action.
