Black et al./ Optics Letters ) University of Texas Arlington scientists have discovered a way to control the growth or repair of neurons and neuron circuits, using a non-invasive “neuronal beacon” (near-IR laser beam) — essentially rewiring brains, or even creating new ones. This major discovery, just published today in Optics Letters , promises to enable several new applications, UT Arlington assistant professor of physics Samarendra Mohanty said in an exclusive interview with KurzweilAI : Building highly precise 3D neural circuits in-vitro as a model for future supercomputers using neuromorphic chips (or even using the neurons themselves in an artificially grown biological computer).
Brain activity mapping, in combination with precision stimulation and imaging tools such as the fiber-optic, two-photon, optogenetic stimulator and label-free phase imaging developed by Mohanty. Guiding axon growth. Scientists sequence genome of ‘sacred lotus,’ may hold anti-aging secrets. Nelumbo nucifera from China, more commonly known as the “sacred lotus” (credit: Jane Shen-Miller/UCLA) A team of 70 scientists from the U.S., China, Australia and Japan reports having sequenced and annotated more than 86 percent of the genome of the “sacred lotus,” which is believed to have a powerful genetic system that repairs genetic defects, and may hold secrets about aging successfully.
The Nelumbo nucifera plant is revered in China and elsewhere as a symbol of spiritual purity and longevity. “Molecular biologists can now more easily study how its genes are turned on and off during times of stress and why this plant’s seeds can live for 1,300 years,” said Jane Shen-Miller, one of three corresponding authors of the research and a senior scientist with UCLA ‘s Center for the Study of Evolution and the Origin of Life. This is a step toward learning what anti-aging secrets the sacred lotus plant may offer.” The research was just published in the journal Genome Biology (open access). Thought experiment: build a supercomputer replica of the human brain. Neocortical column in Henry Markram’s Blue Brain project (Credit: Ecole Polytechnique Fédérale de Lausanne) Henry Markram’s Human Brain Project (HBP), backed by 1 billion euros ($1.3 billion) funding Jan. 2013 from the European Commission, plans to integrate findings from the Allen Brain Atlas, the National Institutes of Health-funded Human Connectome Project, and the Brain (“Brain Activity Map”) project, Wired reports .
The HBP is an ambitious attempt to build a complete model of a human brain using predictive reverse-engineering and simulate it on an IBM Blue Gene supercomputer. Markram plans to give the EU an early working prototype of this system within just 18 months. According to Brown University neuroscientist John Donoghue, one of the key figures in the Brain project, the HBP provides a means to test ideas that would emerge from Brain Activity Map data, and Brain Activity Map data would inform the models simulated in the Human Brain Project. Amazon is developing smartphone with 3D screen. Amazon.com Inc. is developing a high-end smartphone featuring a screen that allows for three-dimensional images without glasses, The Wall Street Journal reports .
Using retina-tracking technology, images on the smartphone would seem to float above the screen like a hologram and appear three-dimensional at all angles, and users may be able to navigate through content using just their eyes, according to sources, With smartphones, Amazon could collect new data on its users through maps, phone calls and app downloads, and offer them shopping recommendations.

Researchers produce first complete computer model of an organism.
July 19, 2012 A mammoth effort has produced a complete computational model of the bacterium Mycoplasma genitalium, opening the door for biological computer-aided design. By Max McClure The Covert Lab incorporated more than 1,900 experimentally observed parameters into their model of the tiny parasite Mycoplasma genitalium. (Illustration: Erik Jacobsen / Covert Lab) In a breakthrough effort for computational biology, the world's first complete computer model of an organism has been completed, Stanford researchers reported last week in the journal Cell. A team led by Markus Covert, assistant professor of bioengineering, used data from more than 900 scientific papers to account for every molecular interaction that takes place in the life cycle of Mycoplasma genitalium, the world's smallest free-living bacterium. By encompassing the entirety of an organism in silico, the paper fulfills a longstanding goal for the field. From information to understanding Small is beautiful Probing the silicon cell.
Research / Projects / First Self-Replicating Synthetic Bacterial Cell / Overview. Genomic science has greatly enhanced our understanding of the biological world.
It is enabling researchers to "read" the genetic code of organisms from all branches of life by sequencing the four letters that make up DNA. Sequencing genomes has now become routine, giving rise to thousands of genomes in the public databases. In essence, scientists are digitizing biology by converting the A, C, T, and G's of the chemical makeup of DNA into 1's and 0's in a computer. But can one reverse the process and start with 1's and 0's in a computer to define the characteristics of a living cell? We set out to answer this question. In the field of chemistry, once the structure of a new chemical compound is determined by chemists, the next critical step is to attempt to synthesize the chemical.
In 2003, JCVI successfully synthesized a small virus that infects bacteria. Now, this scientific team headed by Drs. Synthetic Genomics, Inc. Press Release (Web | PDF) Frequently Asked Questions (Web | PDF) Graphene antennas would enable terabit wireless downloads. Nano-device hardware architecture (credit: Georgia Tech) Researchers at Georgia Tech have drawn up blueprints for a wireless antenna made from atom-thin sheets of carbon, or graphene, that could allow terabit-per-second transfer speeds at a range of about one meter, MIT Technology Review reports This would make it possible to obtain 10 high-definition movies by waving your phone past another device for one second.
At even shorter ranges, such as a few centimeters, data rates of up to 100 terabits per second are theoretically possible. To make an antenna, graphene could be shaped into narrow strips of between 10 and 100 nanometers wide and one micrometer long, allowing it to transmit and receive at a terahertz frequency, which roughly corresponds to those size scales. Electromagnetic waves in the terahertz frequency would then interact with plasmonic waves — oscillations of electrons at the surface of the graphene strip — to send and receive information.

A quadriplegic woman, who hasn’t been able to use her arms, legs, or any muscles below her neck for nine years, has used a mind-controlled robotic arm to perform actions with an unprecedented level of dexterity that approaches the human arm.
For those of you who thought that the US military had a monopoly on such advanced robotics, you’ll be pleased to hear that DARPA partially funded this project. To fully appreciate the beautiful majesty of Jan Scheuermann, a 53-year-old who was diagnosed with spinocerebellar degeneration 13 years ago, controlling her robotic arm, just watch the video below. It’s nine minutes long, but it’s well worth it. If you only have a few minutes, the amazing acts of dexterity begin at the five-minute mark. Now, some technical details. To control the arm, Scheuermann had two electrodes (pictured right), each with 96 tiny pins, inserted into the part of the her motor cortex that deals with moving her right arm. First direct brain-to-brain interface between two animals. Researchers have electronically linked the brains of pairs of rats for the first time, enabling them to communicate directly to solve simple behavioral puzzles (credit: Duke University) Researchers have electronically linked the brains of pairs of rats for the first time, enabling them to communicate directly to solve simple behavioral puzzles.
They even brain-linked two animals thousands of miles apart — one in Durham, North Carolina and one in Natal, Brazil. The researchers think linking multiple brains could form the first “organic computer.” “Our previous studies with brain-machine interfaces had convinced us that the brain was much more plastic than we had thought,” said Duke University Medical Center neurobiologist Miguel Nicolelis . “In those experiments, the brain was able to adapt easily to accept input from devices outside the body and even learn how to process invisible infrared light generated by an artificial sensor.

DNA and amino-acid precursor molecules discovered in interstellar space. The Green Bank Telescope and some of the molecules it has discovered (credit: Bill Saxton, NRAO/AUI/NSF) Researchers have discovered prebiotic (pre-life) molecules in interstellar space that may have formed on dusty ice grains floating between the stars.
The molecules were detected in a giant cloud of gas some 25,000 light-years from Earth, near the center of our Milky Way Galaxy — specifically, the star-forming region Sagittarius(Sgr) B2(N), which is the richest interstellar chemical environment currently known. One of the newly-discovered molecules, called E-cyanomethanimine (E-HNCHCN) is one step in the process that chemists believe produces adenine, one of the four nucleobases that form the “rungs” in the ladder-like structure of DNA.
The other molecule, called ethanamine, is thought to play a role in forming alanine, one of the twenty amino acids in the genetic code.

/J. Neural Eng.) A team of neuroengineers at Brown University has developed a fully implantable and rechargeable wireless brain sensor capable of relaying real-time broadband signals from up to 100 neurons in freely moving subjects. Several copies of the novel low-power device, described in the open-access Journal of Neural Engineering, have been performing well in animal models for more than year, a first in the brain-computer interface field. Brain-computer interfaces could help people with severe paralysis control devices with their thoughts. Neuroscientists can use such a device to observe, record, and analyze the signals emitted by scores of neurons in particular parts of the animal model’s brain. Brain-computer interfaces (BCIs) are used to assess the feasibility of people with severe paralysis being able to move assistive devices like robotic arms or computer cursors by thinking about moving their arms and hands.
What is the Brain Activity Map? A Q&A with George Church. George Church (credit: Steve Jurvetson/Wikimedia Commons) Last summer, six scientists proposed a project they compared in scope and ambition to the Human Genome Project: to map the activity of the human brain. In February, news media reported that the Obama administration plans to move forward with that effort, known as the Brain Activity Map. One of those six scientists was George Church, professor of genetics at Harvard Medical School and a core faculty member of the Wyss Institute for Biologically Inspired Engineering.
Church, who is also a founding investigator of the Human Genome Project (HGP) and Personal Genome Project (PGP). He explained the roots, ambitions and challenges of the Brain Activity Map (BAM). Q: What is a brain activity map? The brain activity map is really a project to enable us to read from and write to individual neurons in complex networks. Q: You say similar to the Human Genome Project. Q: What’s the backstory of the Brain Activity Map?
Q: Why now? Q: And clinical? Brain-machine implant gives rats a 'sixth sense': the ability to detect infrared light. Scientists at the Duke Center for Neuroengineering have successfully given lab rats a sixth sense: the ability to detect infrared light, a part of the electromagnetic spectrum that is normally invisible to them. The rats were wired with a brain-machine interface that included an infrared detector — but the scientists implanted it in the part of the brain that typically processes the sense of touch. Initial training of the rats involved rewarding them with water when they successfully poked their nose into a port attached to a visible LED light. Then, over the course of a month, the researchers gradually replaced the LED lights with infrared lighting; those lights were picked up by sensors attached to the rats' foreheads that connect to the implant in the rat's brain.
These rats have a sixth sense. EL ÚLTIMO VIAJE DEL BUQUE FANTASMA DE GABRIEL GARCÍA MÁRQUEZ. Fotos de Nació Rex, el robot casi humano.

Big Data growth is accelerating as more of the world's activity is expressed digitally. Not only is it increasing in volume, but also in speed, variety and uncertainty. Most data now comes in unstructured forms such as video, images, symbols and natural language - a new computing model is needed in order for businesses to process and make sense of it, and enhance and extend the expertise of humans. Rather than being programmed to anticipate every possible answer or action needed to perform a function or set of tasks, cognitive computing systems are trained using artificial intelligence (AI) and machine learning algorithms to sense, predict, infer and, in some ways, think.
Curiosity. Daniel Wolpert: The real reason for brains. Joshua Foer: Feats of memory anyone can do. Scan Reveals Brain’s Structure To Be Much Simpler Than We Thought. Peering into the brain with a scanner of unprecedented resolution, scientists discovered that the basic structure of neuronal networks was a simple, three-dimensional grid. More than any other part of the brain, the cerebral cortex makes us human. Through the electrical activity of the neuronal networks packed into the brain’s undulating outer surface we sense our environment, use and understand language, and separate good and evil.
So, then, the biologist’s mantra, “form follows function,” means that when we learn about brain structure, we learn about our very nature. Last March a team of scientists used a new and powerful scanner to peer into the cerebral cortex and other underlying structures with an unprecedented level of resolution. What they found surprised them: rather than an incomprehensible bundle of twists and turns, the basic structure of the brain is a simple, three-dimensional grid. The grid structure was seen in our brains and those of our primate cousins as well.
