Micron readies hybrid memory cube for debut

January 18, 2013

hybrid_memory_cube

The next-generation memory-maker Micron Technology‘s Hybrid Memory Cube (HMC) technology is a multi-chip module (MCM) that aims to address one of the biggest challenges in high performance computing: scaling the memory wall, HPC Wire reports.

Memory architectures haven’t kept pace with the bandwidth requirements of multicore processors. As microprocessor speeds out-accelerated DRAM memory speeds, a bottleneck developed that is referred to as the… read more

Mathematicians aim to take publishers out of publishing

Episciences Project to launch series of community-run, open-access journals
January 18, 2013

arxiv

Mathematicians plan to launch a series of free open-access journals that will host their peer-reviewed articles on the preprint server arXiv, Nature News reports. The project was publicly revealed yesterday in a blog post by Tim Gowers, a Fields Medal winner and mathematician at the University of Cambridge, UK.

The initiative, called the Episciences Project, hopes to show that researchers can organize the… read more

A global group of scientists and engineers, including from the University of Southampton, has published in a special issue journal of the Royal Society in support of tidal power, which has the potential to provide more than 20 per cent of the UK’s electricity demand, they calculate.

While the predictable nature of tides makes them an ideal renewable energy source, more so than wind, the… read more

Is the ‘quantum singularity’ near?

January 18, 2013

quantum_aaronson

Four research groups have announced progress on a quantum-computing proposal made two years ago by MIT researchers.

In early 2011, two theoretical computer scientists at MIT proposed an optical experiment that would harness the weird laws of quantum mechanics to perform a computation impossible on conventional computers.

Commenting at the time, Terry Rudolph, a quantum-computing researcher at Imperial College London said that the experiment… read more

Scientists have developed new “superomniphobic” surfaces that will lead to stain-proof, spill-proof clothing, protective garments, and other products that shrug off virtually every liquid — from blood and ketchup to concentrated acids.

Anish Tuteja and colleagues point out that scientists have previously reported “omniphobic” surfaces, the term meaning that such surfaces can cause a range of different liquids to bead up and not spread on them. But… read more

With the rapidly expanding use of brain and spinal cord stimulation therapy (neuromodulation), “remote presence” (telepresence) technologies may help to meet the demand for experts to perform stimulator programming, reports a study published in Neurosurgery.

The preliminary study by Dr. Ivar Mendez of Queen Elizabeth II Health Sciences Centre in Halifax, Nova Scotia, Canada, supports the feasibility and safety of using a telepresence robot (“RP-7″) to increase… read more

Michigan State University (MSU) scientists have redesigned a “robotic fish,” giving it the ability to glide long distances, using little to no energy, while measuring water temperature and quality and other data that can aid in testing and cleaning lakes and rivers.

According to research team leader Xiaobo Tan, MSU associate professor of electrical and computer engineering, while gliding  uses less energy, it’s slower and less… read more

Quantum dots go on display

January 17, 2013

QD-Vision-Color.graph

Researchers working with nanoscale fluorescent particles called quantum dots have long predicted groundbreaking achievements, such as ultra-efficient light-emitting diodes (LEDs) and solar cells, but the technology has found mainly niche applications.

That could change with the announcement last week that QD Vision would supply Sony Corporation of Tokyo with quantum dots for flat-screen televisions that will transmit more richly colored images than other TVs on… read more

A real-life ‘holodeck’ in 10 years?

January 17, 2013

According to software expert Tim Huckaby, we’re on the verge of a science-fiction-like future where doctors manipulate molecules in three-dimensional (3-D) space, augmented music players tune into your thoughts, and retailers deliver coupons in real time based on the focus of your gaze across store shelves, Smart Planet reports.

His predictions for what’s possible within the next 10 years include a functioning “holodeck” (as in Star Trek)… read more

Hands-on with the next generation Kinect: PrimeSense Capri

January 17, 2013

capri_21358236815775

The next generation of PrimeSense‘s 3D sensor (used inside the Microsoft Kinect), called Capri, will revolutionize vision for very cheap and very expensive robots, IEEE Spectrum reports.

Capri is also small enough that it’ll be able to fit into tablets (and eventually smartphones).

The first engineering samples of Capri are expected to ship in 2-3 months, with consumer kits… read more

How the human brain adapts to injury

Findings also show how you can train your brain to handle injuries more efficiently
January 17, 2013

hemisphere takeover

Scientists at the Carnegie Mellon University (CMU) Center for Cognitive Brain Imaging (CCBI) have used a new combination of neural imaging methods to discover exactly how the human brain adapts to injury.

The research shows that when one brain area loses functionality, a “back-up” team of secondary brain areas immediately activates, replacing not only the unavailable area but also its confederates.

Developing… read more

A way to stimulate the brain’s natural defense mechanisms in people with Alzheimer’s disease has been discovered by researchers at Université Laval, CHU de Québec and pharmaceutical firm GlaxoSmithKline (GSK): a molecule known as MPL (monophosphoryl lipid A) that stimulates the activity of the brain’s immune cells.

The breakthrough opens the door to developing a treatment for Alzheimer’s disease and a vaccine to prevent the… read more

Scientists from Berkeley Lab and the National University of Singapore have developed a way to manipulate nanoparticles using an electron beam.

They used an electron beam from a transmission electron microscope to trap gold nanoparticles and direct their movement, and to assemble several nanoparticles into a tight cluster.

They also imaged the nanoparticles as they manipulated them.

Based on their results, the scientists… read more

It sounds like science fiction: “intelligent molecules” that react to external stimuli and reversibly change their shape.

But now Ludwig-Maximilians-Universität (LMU) physicists have succeeded for the first time in creating a chemical reaction, using a single polymer molecule, that makes this process visible.

Dr. Michael Nash and his colleagues placed a self-generated synthesized polymer on a gold surface using an atomic force microscope… read more
