Brain simulation breakthrough reveals clues about sleep, memory
Posted by Albert Sanchez in categories: information science, neuroscience, supercomputing
The Blue Brain Project is a vast effort by 82 scientists worldwide to digitally recreate the human brain. While still far from that goal, the team revealed a breakthrough that has already provided insight into sleep, memory and neurological disorders. They created a simulation of a third of a cubic millimeter of a rat’s brain. While that might not sound like much, it involves 30,000 neurons and 37 million synapses. In addition, the simulated level of biological accuracy is far beyond anything so far. It allowed them to reproduce known brain activities — such as how neurons respond to touch — and has already yielded discoveries about the brain that were impossible to get biologically.
To create the simulation, researchers did thousands of experiments on rat brains over a 20 year period, logging each type of synapse and neuron discovered. That led to a set of fundamental rules describing how neurons connect to synapses and form microcircuits. Using the data, they developed an algorithm to pinpoint the synapse locations, simulating the circuitry of a rat’s brain. All of that data was then run through a supercomputer: “It was only with this kind of infrastructure that we could solve the billions of equations needed,” said software lead Felix Schurmann.

A quantum logic gate in silicon built for the for the first time (w/video)
Posted by Simon Waslander in categories: computing, encryption, quantum physics, supercomputing
A Game Changer in Quantum Computing:
The ingredients for superfast computers could be nearly in place. For the first time, researchers have demonstrated that two silicon transistors acting as quantum bits can perform a tiny calculation.
The advance represents the final physical component needed to realise the promise of super-powerful silicon quantum computers, which harness the science of the very small — the strange behaviour of subatomic particles — to solve computing challenges that are beyond the reach of even today’s fastest supercomputers. Potentially transforming fields like encryption and the search for new pharmaceuticals.

New ‘stealth dark matter’ theory may explain mystery of the universe’s missing mass
Posted by Sean Brazell in categories: cosmology, supercomputing
A new theory that may explain why dark matter has evaded direct detection in Earth-based experiments has been developed by team of Lawrence Livermore National Laboratory (LLNL) particle physicists known as the Lattice Strong Dynamics Collaboration.
The group has combined theoretical and computational physics techniques and used the Laboratory’s massively parallel 2-petaflop Vulcan supercomputer to devise a new model of dark matter. The model identifies today’s dark matter as naturally “stealthy.” But in the extremely high-temperature plasma conditions that pervaded the early universe, it would have been easy to see dark matter via interactions with ordinary matter, the model shows.
Replacing metal wiring with fiber optics could change everything from supercomputers to laptops.

Watson is getting closer and closer to being your doctor
Posted by Shailesh Prasad in categories: biotech/medical, health, supercomputing
Sure, it can beat Ken Jennings at Jeopardy, tell you about your city, and dream up recipes for delectable delicacies, but now, IBM’s Watson is doing something even more important than all previous capabilities combined — it’s finally getting closer to becoming your doctor. Last April, the century-old company launched IBM Watson Health, and now, it’s opened up a new office in Cambridge, Massachusetts, home to some of the best universities in the U.S., and some of the most impressive biotech and pharmaceutical companies as well. In the last few months, Watson has already expanded its scope to take on some of our most pressing health issues and diseases, including cancer and diabetes, and with this new establishment, it seems that the supercomputer will only be taking on greater responsibilities in the industry.
More exciting still is the announcement that Deborah DiSanzo, the former CEO of Philips Healthcare, will be leading the unit as its general manager. Under her leadership, IBM hopes that Watson Health will be able to grow and further expand its massive cloud computing capabilities, which the company believes holds significant potential for modern health care. While current “health record systems can do great job storing data,” Mike Rhodin, senior vice president of the IBM Watson Group, told Fortune, “Watson can summarize that data and incorporate nurse and doctor’s notes to give a more complete picture.”
