Electronic circuits with reconfigurable pathways closer to reality

Mon, 01/26/2015 - 17:49
Multitasking circuits capable of reconfiguring themselves in real time and switching functions as the need arises -- this is the promising application stemming from a new discovery. Other potential uses: miniaturizing our electronic devices and developing resilient circuits.

Largest-ever autism genome study finds most siblings have different autism-risk genes

Mon, 01/26/2015 - 17:46
The largest-ever autism genome study reveals that the disorder's genetic underpinnings are more complex than previously thought: Most siblings who have autism have different autism-linked genes. The study's data is part of the historic first upload of approximately 1,000 autism genomes to the Autism Speaks MSSNG portal in Google Cloud Platform. The data will be openly available for global research in order to speed understanding of autism and the development of individualized treatments.

Researchers identify materials to improve biofuel, petroleum processing

Mon, 01/26/2015 - 16:23
Using one of the largest supercomputers in the world, a team of researchers has identified potential materials that could improve the production of ethanol and petroleum products. The discovery could lead to major efficiencies and cost savings in these industries.

Device for guided surgery of deviations in long bones patented

Mon, 01/26/2015 - 16:22
A device that can be applied in surgeries to correct deviations in long bones has been patented by researchers. The research team found how to use the 3D reconstruction of an affected bone to determine the mathematical formula that in a given case is suitable to design such a device. This device is adjusted to a specific deviated bone and enables a surgeon to set the cutting angle that best suits the bone, and, also, to set the location and orientation of holes that accept the future addition of a corrective prosthesis. It enables realigning the body extremity that is operated on, and also increases precision, shortens the time required for the operation, and improves the operation’s functional results. The device has already been used with success in operations on animals and could have applications in orthopedic surgery on humans.

Researchers make magnetic graphene

Mon, 01/26/2015 - 14:59
Graphene has many desirable properties. Magnetism alas is not one of them. Magnetism can be induced in graphene by doping it with magnetic impurities, but this tends to disrupt graphene's electronic properties. Now physicists have found a way to induce magnetism in graphene while also preserving graphene's electronic properties. They have accomplished this by bringing a graphene sheet very close to a magnetic insulator -- an electrical insulator with magnetic properties.

Stock market changes: Patents provide insight into Wall Street 'technology arms race'

Mon, 01/26/2015 - 14:59
A new study has used US patent data to shed light on the technological roots behind Wall Street's ongoing 'technology arms race.' The way financial assets are traded, and the nature of the markets themselves, has dramatically changed over the last two decades, according to new research.

Chemists control structure to unlock magnetization and polarization simultaneously

Mon, 01/26/2015 - 14:59
Scientists have controlled the structure of a material to simultaneously generate both magnetization and electrical polarization, an advance which has potential applications in information storage and processing.

How cancer turns good cells to the dark side

Mon, 01/26/2015 - 14:57
Biophysicists reveal how cancer uses notch-signaling pathways to promote metastasis. Their computer models provide a fresh theoretical framework for scientists who study ways to target cancer progression.

Entanglement on a chip: Breakthrough promises secure communications and faster computers

Mon, 01/26/2015 - 14:57
A team of scientists has developed, for the first time, a microscopic component that is small enough to fit onto a standard silicon chip that can generate a continuous supply of entangled photons.

Medical radiation may be reduced to one-sixth with new mathematical discovery

Mon, 01/26/2015 - 13:40
One of this century's most significant mathematical discoveries may reduce the number of measuring points to one-sixth of the present level. This means reduced exposure to radiation and faster medical imaging diagnostics.

New programming language for fast simulations

Mon, 01/26/2015 - 13:39
Programming is a time-consuming process, and it may take many years to develop even a basic simulator. Researchers want to simplify this process. They have created a language similar to the language of mathematics. This allows them to subdivide the work process in such a way that reduces the time it takes to develop a simulator. A mathematician can then focus on what he or she knows best -- the simulator's area of application. Programming experts, on the other hand, can sit and work with "the translator" in order that the translated code can run faster, and they don't have to worry about the application.

Digital storytelling promotes HIV/AIDS education in Africa

Mon, 01/26/2015 - 13:38
Children from poor backgrounds and with no previous technological experience are able to use digital storytelling to share their secrets and fears online, shows a recent doctoral thesis. The author has been involved in various projects in southern Africa focusing on the development of technologies that make it possible for children and youth to share their experiences of HIV and AIDS. Digital storytelling incorporates various types of media, including text, images, animations and sound.

3-D view of Greenland Ice Sheet opens window on ice history

Fri, 01/23/2015 - 19:09
Scientists using ice-penetrating radar have created 3-D maps of the age of the ice within the Greenland Ice Sheet. The new maps will aid future research to understand the impact of climate change on the ice sheet. The Greenland Ice Sheet is the second largest mass of ice on Earth, containing enough water to raise ocean levels by about 20 feet.

Silver nanowires demonstrate unexpected self-healing mechanism: Potential for flexible electronics

Fri, 01/23/2015 - 16:07
Researchers found that silver nanowires can withstand strong cyclic loads, which is a key attribute needed for flexible electronics.

Stalking versus cyberstalking: Effects on victims, their responses compared

Fri, 01/23/2015 - 16:07
The devastating effects of stalking and cyberstalking – harassing or threatening communication via the Internet – are explored in a new study. Key among the findings is that victims of cyberstalking engage in more 'self-protective' behaviours -- such as changing their normal routines or getting a new email address -- than victims of stalking.

Massive chip design savings to be realized

Fri, 01/23/2015 - 13:17
IT researchers have developed a programming language making the massive costs associated with designing hardware more manageable. Chip manufacturers have been using the same chip design techniques for twenty years now. The current process calls for extensive testing after each design step - a massively expensive state of affairs. The newly developed, so-called  functional  programming language makes it possible to prove, in advance, that a design transformation is a hundred percent error-free.

Improvements in transistors will make flexible plastic computers a reality

Fri, 01/23/2015 - 13:12
Researchers revealed that improvements should soon be expected in the manufacture of transistors that can be used, for example, to make flexible, paper-thin computer screens.

Falls in blood pressure, cholesterol have saved 20,000+ lives in England

Fri, 01/23/2015 - 00:39
Falls in blood pressure and total cholesterol staved off more than 20,000 deaths from coronary heart disease in England between 2000 and 2007, shows a mathematical analysis. The impact of statins was greatest among the most affluent in the population, suggesting that these drugs have helped maintain health inequalities between rich and poor, say the researchers.

Pro-marijuana 'tweets' are sky-high on Twitter

Thu, 01/22/2015 - 21:59
Analyzing every marijuana-related Twitter message sent during a one-month period in early 2014, researchers have found that the 'Twitterverse' is a pot-friendly place. In that time, more than 7 million tweets referenced marijuana, with 15 times as many pro-pot tweets sent as anti-pot tweets.
