A little light interaction leaves quantum physicists beaming

August 24, 2015 2:00 pm | by Univ. of Toronto | Comments

A team of physicists at the Univ. of Toronto (U of T) have taken a step toward making the essential building block of quantum computers out of pure light. Their advance, described in a paper published in Nature Physics, has to do with a specific part of computer circuitry known as a "logic gate."

Biological tools create nerve-like polymer network

August 24, 2015 1:00 pm | by Neal Singer, Sandia National Laboratories | Comments

Using a succession of biological mechanisms, Sandia National Laboratories researchers have created linkages of polymer nanotubes that resemble the structure of a nerve, with many out-thrust filaments poised to gather or send electrical impulses.

After a half century, the exotic pentaquark particle is found

August 24, 2015 12:00 pm | by Rod Pyle, Caltech | Comments

In July, scientists at the Large Hadron Collider reported the discovery of the pentaquark, a long-sought particle first predicted to exist in the 1960s as a consequence of the theory of elementary particles and their interactions proposed by Murray Gell-Mann, Caltech's Robert Andrews Millikan Professor of Theoretical Physics, Emeritus.

Imaging software could speed breast cancer diagnosis

August 24, 2015 11:00 am | by Jade Boyd, Rice Univ. | Comments

New software developed by Rice Univ. bioengineers could speed up the diagnosis of breast cancer with 90% accuracy and without the need for a specialist, according to research published in Breast Cancer Research. Researchers said the software could improve breast cancer management, particularly in developing countries where pathologists are not routinely available.

Crash-tolerant data storage

August 24, 2015 10:00 am | by Larry Hardesty, MIT News Office | Comments

In a computer operating system, the file system is the part that writes data to disk and tracks where the data is stored. If the computer crashes while it’s writing data, the file system’s records can become corrupt. Hours of work could be lost, or programs could stop working properly.

Genomes uncover life’s early history

August 24, 2015 9:30 am | by Univ. of Manchester | Comments

A Univ. of Manchester scientist is part of a team which has carried out one of the biggest ever analyses of genomes on life of all forms. This has allowed them to map the evolutionary history of eukaryotic genes in unprecedented detail, giving insight into the mechanisms of evolution in the very earliest forms of life.

Intractable pain may find relief in tiny gold rods

August 24, 2015 9:00 am | by Kyoto Univ. | Comments

A team of scientists at Kyoto Univ.'s Institute for Integrated Cell-Material Sciences (iCeMS) has developed a novel technique using tiny gold rods to target pain receptors. Gold nanorods are tiny rods that are 1 to 100 nm wide and long. In comparison, a human hair is 100,000 nm wide. The team coated gold nanorods with a special type of protein that transports fat within the body known as a lipoprotein.

Graphene oxide’s secret properties revealed at atomic level

August 24, 2015 8:00 am | by Amanda Morris, Northwestern Univ. | Comments

Since its discovery, graphene has captured the attention of scientists and engineers for its many extraordinary properties. But graphene oxide, an oxidized derivative of graphene, largely has been viewed as graphene’s inferior cousin. Now a Northwestern Univ. team has found that graphene oxide’s seemingly undesirable defects surprisingly give rise to exciting mechanical properties.

Smooth robot movements reduce energy consumption by 40%

August 24, 2015 7:27 am | by Chalmers Univ. of Technology | Comments

By minimizing the acceleration of industrial robots, energy consumption can be reduced by up to 40%, while retaining the given production time. This is the result of a new optimization algorithm that was developed by researchers at Chalmers Univ. of Technology. Optimization of the robot's movements reduces acceleration and deceleration, as well as the time the robot is at a standstill since being at a standstill also consumes energy.

Superlattice design realizes elusive multiferroic properties

August 21, 2015 5:00 pm | by Amanda Morris, Northwestern Univ. | Comments

From the spinning disc of a computer’s hard drive to the varying current in a transformer, many technological devices work by merging electricity and magnetism. But the search to find a single material that combines both electric polarizations and magnetizations remains challenging.

Researchers developing next generation of high-power lasers

August 21, 2015 4:00 pm | by Univ. of Strathclyde | Comments

Researchers at the Univ. of Strathclyde are developing groundbreaking plasma based light amplifiers that could replace traditional high-power laser amplifiers. The research group at the Glasgow-based university are leading efforts to take advantage of plasma, the ubiquitous medium that makes up most of the universe, to make the significant scientific breakthrough.

Venus flytrap inspires development of folding “snap” geometry

August 21, 2015 3:00 pm | by Univ. of Massachusetts Amherst | Comments

Inspired by natural "snapping" systems like Venus flytrap leaves and hummingbird beaks, a team led by physicist Christian Santangelo at the Univ. of Massachusetts Amherst has developed a way to use curved creases to give thin curved shells a fast, programmable snapping motion. The new technique avoids the need for complicated materials and fabrication methods when creating structures with fast dynamics.

Micro-hydropower electricity generation could save water industry millions

August 21, 2015 12:00 pm | by Bangor Univ. | Comments

New research findings from Bangor Univ. and Trinity College Dublin have highlighted the potential for further cost savings from micro-hydropower. Savings of up to an additional £1m a year in Wales alone could help keep water bills down. The water industry consumes a vast amount of energy due to the need to treat, pump and distribute water and wastewater around the country.
