In what they are calling a major milestone, researchers in the John Martinis Lab at UC Santa Barbara have developed quantum circuitry that self-checks for errors and suppresses them — preserving the qubits’ state(s) and imbuing the system with reliability that is foundational for building powerful large-scale superconducting quantum computers.

“One of the biggest challenges in quantum computing is that qubits are inherently faulty,” said Julian Kelly,… read more

Kids and robots learn to write together

March 5, 2015

Kids and robots2

EPFL researchers have developed a new teaching tool called CoWriter based on the pedagogical principle of “learning by teaching.”

When children experience difficulties in writing, they can easily lose confidence, begin to shut down, or even gradually lose interest in the learning process. Eventually, their entire education can be affected. When students put themselves in the place of a teacher and pass on what they know to their peers,… read more

The European Union predicts that electric vehicles (EV) could be in mass production by 2020. But what might be their impacts, such as new demands on electrical distribution grids and on how and where we travel?

The EU DATA SIM project, a  consortium of nine partners from seven countries with EUR 2,3 million investment from the EU, was created for that purpose.

It has… read more

Flexible sensors turn skin into a touch-sensitive interface for mobile devices

March 4, 2015

iSkin2

Computer scientists at Saarland University and Carnegie Mellon University are studying the potential use of the human body as a touch sensitive surface for controlling mobile devices. They have developed flexible silicone rubber stickers with pressure-sensitive sensors that fit snugly to the skin.

By operating these touch input stickers, users can use their own body to control mobile devices. Because of the flexible material used, the sensors can be… read more

Researchers enable solar cells to use more sunlight

March 4, 2015

Scientists of the University of Luxembourg and of the Japanese electronics company TDK have extended sensitivity of a conductive oxide film used in solar cells in the near-infrared region to use more energy of the sun and thus create higher current.

Similar attempts have been made before, but this is the first time that these films were prepared by a one-step process and, at the same time, stable in… read more

Rice University researchers have formed graphene nanoribbons into a three-dimensional aerogel enhanced with boron and nitrogen as catalysts for fuel cells as a replacement for platinum.

In tests involving half of the catalytic reaction that takes place in fuel cells, a team led by materials scientist Pulickel Ajayan and chemist James Tou discovered that versions with about 10 percent boron and nitrogen were efficient in catalyzing an… read more

Black phosphorus improves optical communication for chip interconnects

University of Minnesota researchers have found that an ultrathin black phosphorus film — only 20 layers of atoms — allows for high-speed data communication on nanoscale optical circuits. Black phosphorus is a crystaline form of the element phosphorus.

The devices showed vast improvement in efficiency over comparable devices using graphene.

By measuring a series of diffraction pattern from a virus injected into an XFEL beam, researchers at Stanford’s Linac Coherent Light Source (LCLS) have determined the first three-dimensional structure of a virus, using a mimivirus.

X-ray crystallography has solved the vast majority of the structures of proteins and other biomolecules. The success of the method relies on growing large crystals of the molecules, which isn’t possible… read more

We can make multicore chips smarter, faster — we have the technology

(credit: Christine Daniloff/MIT)

Computer chips’ clocks have stopped getting faster, so chipmakers are instead giving chips more cores, which can execute computations in parallel.

Now, in simulations involving a 64-core chip, MIT computer scientists have improved a system that cleverly distributes data around multicore chips’ memory banks — increasing system computational speeds by 46 percent while reducing power consumption by 36 percent.

“Now that the way to improve performance is… read more

Researchers at Queen’s University Belfast, the University of Manchester, and the STFC Daresbury Laboratory are developing new software to increase the ability of supercomputers to process big data faster while minimizing increases in power consumption.

To do that, computer scientists in the Scalable, Energy-Efficient, Resilient and Transparent Software Adaptation (SERT) project are using “approximate computing” (also known as “significance-based computing”) — a form… read more

A superconductor advance using ‘superatoms’

Superconductivity is the ability to transmit electricity without resistance (credit: USC/Original image/DC Comics Mystery in Space #56, December 1959)

USC scientists may have discovered a family of superconductor materials called superatoms that could lead to room-temperature supercomputers.

A team led by Vitaly Kresin, professor of physics at the USC Dornsife College of Letters, Arts and Sciences, found that aluminum “superatoms” — homogenous clusters of atoms — appear to form Cooper pairs of electrons (one of the key elements of superconductivity) at temperatures around 100 Kelvin.

Though 100… read more

We could get to the singularity in ten years

It would require a different way of thinking about the timing of the Singularity, says AGI pioneer Ben Goertzel, PhD. Rather than a predictive exercise, it would require thinking about it the way an athlete thinks about a game when going into it, or the way the Manhattan Project scientists thought at the start of the project.

Additive manufacturing — or 3D printing — is 30 years old this year. Today, it’s found not just in industry but in households, as the price of 3D printers has fallen below US$1,000. Knowing you can print almost anything, not just marks on paper, opens up unlimited opportunities for us to manufacture toys, household appliances and tools in our living rooms.
