An internet for robots

Researchers of five European universities have developed a cloud-computing platform for robots. The platform allows robots connected to the Internet to directly access the powerful computational, storage, and communications infrastructure of modern data centers - the giant server farms behind the likes of Google, Facebook, and Amazon - for robotics tasks and robot learning.

New player in electron field emitter technology makes for better imaging and communications

Scientists at the National Institute of Standards and Technology (NIST) and the University of Maryland, College Park, have built a practical, high-efficiency nanostructured electron source. Described in the journal Nanotechnology*, this new, patent-pending technology could lead to improved microwave communications and radar, and more notably to new and improved X-ray imaging systems for security and health-care applications.

Stanford scientists calculate the carbon footprint of grid-scale battery technologies

Americans take electrical power for granted whenever they flip on a light switch. But the growing use of solar and wind power in the United States makes the on-demand delivery of electricity more challenging.

A key problem is that the U.S. electrical grid has virtually no storage capacity, so grid operators can't stockpile surplus clean energy and deliver it at night, or when the wind isn't blowing.

Engineers develop techniques to boost efficiency of cloud computing infrastructure

Computer scientists at the University of California, San Diego, and Google have developed a novel approach that allows the massive infrastructure powering cloud computing as much as 15 to 20 percent more efficiently. This novel model has already been applied at Google. Researchers presented their findings at the IEEE International Symposium on High Performance Computer Architecture conference Feb. 23 to 27 in China.

U of T engineering breakthrough promises significantly more efficient solar cells

TORONTO, ON – March 7, 2013: A new technique developed by U of T Engineering Professor Ted Sargent and his research group could lead to significantly more efficient solar cells, according to a recent paper published in the journal Nano Letters.

As Brazil ramps up sugarcane production researchers foresee regional climate effects

TEMPE, Ariz. – Conversion of large swaths of Brazilian land for sugar plantations will help the country meet its needs for producing cane-derived ethanol but it also could lead to important regional climate effects, according to a team of researchers from Arizona State University, Stanford University and the Carnegie Institution for Science.

The team found that anticipated conversion to sugarcane plantations could lead to a 1°C decrease in temperature during the growing season, to be followed by a 1°C increase after harvest.

Illuminating fractures: X-ray imaging sheds new light on bone damage

ITHACA, N.Y. — From athletes to individuals suffering from osteoporosis, bone fractures are usually the result of tiny cracks accumulating over time -- invisible rivulets of damage that, when coalesced, lead to that painful break.

Using cutting-edge X-ray techniques, Cornell University researchers have uncovered cellular-level detail of what happens when bone bears repetitive stress over time, visualizing damage at smaller scales than previously observed. Their work could offer clues into how bone fractures could be prevented.

Biobatteries catch breath

An air-breathing bio-battery has been constructed by researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw. The core element providing the new power source with relatively high voltage and long lifetime is a carefully designed cathode taking up oxygen from air and composed of an enzyme, carbon nanotubes and silicate.

Ketchup turns somersaults

The unusual behavior of complex fluids is part of our daily life: cake dough climbs up the stirring bar, ketchup becomes liquid when you shake it. Also technology uses such phenomena: if we add a small amount of long-chained polymer molecules, a pipeline can transport more oil. The polymers reduce the flow resistance. But up to now the origin of these effects was unclear. The engineers had to rely on estimates and lengthy trials.

Federal figures miss most work-related amputations

A new report from Michigan State University and the Michigan Department of Community Health raises significant concerns about the federal government's system for tracking work-related injuries.

Published in the Journal of Occupational and Environmental Medicine, the study found the number of amputations following jobsite accidents in Michigan was nearly two-and-a-half times higher than the official estimate from the U.S. Bureau of Labor Statistics.

UTHealth researchers find industrial chemicals in food samples

HOUSTON – (March 6, 2013) – Researchers at The University of Texas Health Science Center at Houston (UTHealth) have discovered phthalates, industrial chemicals, in common foods purchased in the United States. Phthalates can be found in a variety of products and food packaging material, child-care articles and medical devices.

How to predict the progress of technology

CAMBRIDGE, MA -- Researchers at MIT and the Santa Fe Institute have found that some widely used formulas for predicting how rapidly technology will advance — notably, Moore's Law and Wright's Law — offer superior approximations of the pace of technological progress. The new research is the first to directly compare the different approaches in a quantitative way, using an extensive database of past performance from many different industries.

INRS overcomes a hurdle in the development of terahertz lasers

Novel marker helps identify preeclampsia risk in pregnancy

SAN FRANCISCO (March 7, 2013) — Pregnant women who have a reduced number of capillaries under their skin during pregnancy may be at heightened risk for preeclampsia, according to research being presented at the American College of Cardiology's 62nd Annual Scientific Session. Researchers say monitoring such changes in small blood vessels early in pregnancy may allow for medical intervention long before the potentially life-threatening condition occurs.

A new material using doped carbon allows fuels to be produced while reducing CO2 emissions

Researchers from the University of Granada (UGR) have developed a new material using doped carbon that allows low-cost energy to be produced and also reduces the amount of CO2 released into the atmosphere. The recently-patented material is a gel that enables the CO2 to be turned back into hydrocarbons via electro-catalytic transformation, with great savings both in time and money
