Creating Superwoman (and man): Who benefits from human enhancement? INSIS - Un neurone artificiel mille fois plus économe en énergie qu’un neurone biologique. 10 avril 2017 Chef d’œuvre de l’évolution, le cerveau humain est une source d’inspiration pour les scientifiques.
Des chercheurs de l’IEMN et de l’Ircica ont ainsi mis au point un neurone artificiel ultra-efficace en énergie et qui reproduit très précisément les signaux électriques générés dans le cerveau. Ces travaux sont publiés dans la revue Frontiers in Neuroscience. Dans notre cerveau, les neurones sont connectés entre eux et génèrent une réponse binaire aux informations qu’ils reçoivent des autres cellules nerveuses : soit ils émettent un signal électrique, appelé aussi potentiel d’action, soit ils restent silencieux. Ce système est à la base de tous nos processus cognitifs et moteurs. Mesurant quelques microns carrés, ces neurones artificiels sont disposés en grand nombre sur un circuit intégré en silicium.

Cet article est une synthèse d’une interview qui sera diffusée dans l’émission de Jérôme Bonaldi Le Mag de la Science, sur la chaîne Science&Vie TV en juin prochain. Scientists turn mammalian cells into complex biocomputers. Computer hardware is getting a softer side.
A research team has come up with a way of genetically engineering the DNA of mammalian cells to carry out complex computations, in effect turning the cells into biocomputers. The group hasn’t put those modified cells to work in useful ways yet, but down the road researchers hope the new programming techniques will help improve everything from cancer therapy to on-demand tissues that can replace worn-out body parts.
Engineering cells to function like minicomputers isn’t new. Les ordinateurs ADN qui "s'auto-augmentent" vont tout changer. Les ordinateurs ont sans aucun doute révolutionné la société moderne.
Ils sont partout : dans nos bureaux, nos maisons, nos poches et même dans nos appareils de cuisine. The Brain Tech to Merge Humans and AI Is Already Being Developed. Are you scared of artificial intelligence (AI)?
Do you believe the warnings from folks like Prof. Stephen Hawking, Elon Musk and others? Is AI the greatest tool humanity will ever create, or are we “summoning the demon”? To quote the head of AI at Singularity University, Neil Jacobstein, “It’s not artificial intelligence I’m worried about, it’s human stupidity.”
In a recent Abundance 360 webinar, I interviewed Bryan Johnson, the founder of a new company called Kernel which he seeded with $100 million. To quote Bryan, “It’s not about AI vs. humans. It's Alive! Artificial-Life Worm Wiggles on Its Own. A worm wiggles.
Will We Ever Be Able To Bring Cryogenically Frozen Corpses Back To Life? A Cryobiologist Explains. A teenager who tragically died of cancer recently has become the latest among a tiny but growing number of people to be cryogenically frozen after death.
These individuals were hoping that advances in science will one day allow them to be woken up and cured of the conditions that killed them. But how likely is it that such a day will ever come? Nature has shown us that it is possible to cryopreserve animals like reptiles, amphibians, worms and insects. Nematode worms trained to recognise certain smells retain this memory after being frozen. ?articles. Researchers swap microscopy for RNA sequencing to track neural paths in the mouse brain.
FOLLOW THE mRNA: To determine where in the mouse brain individual neurons have axon terminals, researchers inject a library of viral vectors in the vicinity of cell bodies. The viruses contain plasmids each encoding a unique RNA barcode and a presynaptic protein called MAPP-nλ that will shuttle the barcoded mRNA to the ends of the axon. Typically, each cell takes up only one virus, giving that cell an RNA identifier. Dissecting brain regions and sequencing the RNAs reveals which cells project where.© GEORGE RETSECK. Biohybrid Robots Built From Living Tissue Start To Take Shape. Think of a traditional robot and you probably imagine something made from metal and plastic.
Such “nuts-and-bolts” robots are made of hard materials. As robots take on more roles beyond the lab, such rigid systems can present safety risks to the people they interact with. Les promesses du contrôle quantique. Contrôler les réactions chimiques par laser, manipuler les bits d’un ordinateur quantique, améliorer les images des IRM… Voilà ce que promet le contrôle quantique, une discipline en plein boom qui s’apprête à révolutionner notre quotidien.
Laser, microprocesseur, GPS, imagerie par résonance magnétique… Aujourd’hui, sans qu’on s’en rende compte, de nombreuses techniques utiles dans la vie de tous les jours n’auraient pas pu voir le jour sans la mécanique quantique, une théorie inventée dans les années 1920 qui décrit les phénomènes physiques à l’échelle des atomes. « Mais aussi importantes soient-elles, ces applications s’appuient seulement sur une compréhension passive des lois quantiques, note Dominique Sugny, du Laboratoire interdisciplinaire Carnot de Bourgogne1, à Dijon, et de l’Institute for Advanced Study de Munich, en Allemagne.
CRISPR-Enabled Bacteria Transformed Into Self-Replicating Biological Hard Drive. Silicon-based memory storage is reaching an impasse.
Like batteries, the technology hasn’t evolved very much over the last few decades, apart from getting smaller and more powerful, and there’s only so small we can get before the devices will stop working. With this in mind, researchers around the world have recently demonstrated that the future of memory may be in biology, not technology. Just this year, one team demonstrated how the whole of human history could be stored on a drop of DNA. Now, as revealed in a new paper in Science, colonies of bacteria have been converted into information-storing critters – or, to put it another way, biological hard drives. Revolutionary Brain Implant Restores Hand Movement In Quadriplegic Patient.
For many, paralysis or limb loss is a lifelong burden, and scientists across the world have been working around the clock to restore movement to these unfortunate few. Now, a new Nature study showcases what is not just a step but a leap forward in medical science. A young man, who became a quadriplegic during a diving accident, is today able to grasp objects and even play video games using his own hand and fingers, after a novel device was surgically inserted into his brain. This Amazing Computer Chip Is Made of Live Brain Cells. A few years ago, researchers from Germany and Japan were able to simulate one percent of human brain activity for a single second. It took the processing power of one of the world’s most powerful supercomputers to make that happen.
Hands down, the human brain is by far the most powerful, energy efficient computer ever created. So what if we could harness the power of the human brain by using actual brain cells to power the next generation of computers? As crazy as it sounds, that’s exactly what neuroscientist Osh Agabi is building. Koniku, Agabi’s startup, has developed a prototype 64-neuron silicon chip.

NSI mondada. Scientists Discover "Intelligence" Genes That Code For Cognitive Ability. Cognitive ability, such as decision-making skills, varies wildly from person to person, and although it is acknowledged that both genes and the environment play a role in this variation, linking specific genes to healthy cognitive abilities has proven incredibly difficult. Researchers have figured out how to store the entire Internet in a test tube. Engineer Robert Grass says that though we believe information is here forever, it’s actually fragile. Hard drives and physical sources of information, like books, decay over time. In a video for the BBC, Grass describes his quest to find a method of preserving information that could be stable for millions of years. The secret is DNA. In 2012, research showed that you could translate a megabyte (MB) of information into DNA and then read it back again.
DNA has a language of its own, and is written in sequences of nucleotides (A, C, T, and G). DNA to play an essential role in the future of Computers? - Labiotech.eu. Human Brain Grown In A Lab Could Be Most Complete Yet. Bacterial “Brain” Could Control Robots. If the Google driverless car makes you feel a bit uneasy, how will you cope with bacteria-driven robots? Such robots, declare Virginia Tech scientists, could have “brains” that rely not on neurotransmitters and electrical signals that pass between neurons, but rather on the biochemical signals that pass between microorganisms.
