Quantum computers could help search engines keep up with the Internet's growth

Most people don't think twice about how Internet search engines work. You type in a word or phrase, hit enter, and poof – a list of web pages pops up, organized by relevance.

Voicemail discovered in nature

Insects can use plants as 'green phones' for communication with other bugs. A new study now shows that through those same plants insects are also able to leave 'voicemail' messages in the soil. Herbivorous insects store their voicemails via their effects on soil fungi. Researchers from the Netherlands Institute of Ecology (NIOO-KNAW) and Wageningen University (WUR) discovered this unique messaging service in the ragwort plant. The influential journal Ecology Letters will soon publish these results.

Radiation-resistant circuits from mechanical parts

SALT LAKE CITY, June 12, 2012 – University of Utah engineers designed microscopic mechanical devices that withstand intense radiation and heat, so they can be used in circuits for robots and computers exposed to radiation in space, damaged nuclear power plants or nuclear attack.

The researchers showed the devices kept working despite intense ionizing radiation and heat by dipping them for two hours into the core of the University of Utah's research reactor. They also built simple circuits with the devices.

Keeping pace: Walking speed may signal thinking problems ahead

MINNEAPOLIS – A new study shows that changes in walking speed in late life may signal the early stages of dementia known as mild cognitive impairment (MCI). The research is published in the June 12, 2012, print issue of Neurology®, the medical journal of the American Academy of Neurology.

Study finds new evidence supporting theory of extraterrestrial impact

(Santa Barbara, Calif.) –– An 18-member international team of researchers that includes James Kennett, professor of earth science at UC Santa Barbara, has discovered melt-glass material in a thin layer of sedimentary rock in Pennsylvania, South Carolina, and Syria. According to the researchers, the material –– which dates back nearly 13,000 years –– was formed at temperatures of 1,700 to 2,200 degrees Celsius (3,100 to 3,600 degrees Fahrenheit), and is the result of a cosmic body impacting Earth.

Global warming threat seen in fertile soil of northeastern US forests

Irvine, Calif. – June 11, 2012 -Vast stores of carbon in U.S. forest soils could be released by rising global temperatures, according to a study by UC Irvine and other researchers in today's online Proceedings of the National Academy of Sciences in Washington, D.C.

The scientists found that heating soil in Wisconsin and North Carolina woodlands by 10 and 20 degrees increased the release of carbon dioxide by up to eight times. They showed for the first time that most carbon in topsoil is vulnerable to this warming effect.

Robotics helps us become more competitive

The event, "RoboCity12: Robots para los ciudadanos" (Robots for the people), hosted by the Escuela Técnica Superior de Ingenieros Industriales (School of Industrial Engineering - ETSII) of the Universidad Politécnica de Madrid (UPM), gathered nearly 40 robots "made in Spain" for two days. The objective was to present the most recent advances in robotics that have been developed in the Community of Madrid, as well as the main innovations that have appeared on the national and international scenes.

Studies challenge established views development of children raised by gay or lesbian parents

Oxford, June 10, 2012 - Despite considerable research showing that children of same-sex parents fare just as well as children with heterosexual parents, two papers - a review of existing studies and a new study - published today in Elsevier's Social Science Research, find insufficient data to draw any definitive conclusions.

Study examines impact of African-American teachers in Title I schools

Closing the academic gaps in performance among students from diverse backgrounds is a challenge for schools and a mandate from the government. The No Child Left Behind Act of 2001 has prompted schools and school districts to re-examine elements that impact student achievements.

Does cooperation require both reciprocity and alike neighbors?

Environmental benefit of biofuels is overestimated, new study reveals

Two scientists are challenging the currently accepted norms of biofuel production. A commentary published today in GCB Bioenergy reveals that calculations of greenhouse gas (GHGs) emissions from bioenergy production are neglecting crucial information that has led to the overestimation of the benefits of biofuels compared to fossil fuels.

Engineered robot interacts with live fish

A bioinspired robot has provided the first experimental evidence that live zebrafish can be influenced by engineered robots.

Results published today, 8 June, in IOP Publishing's journal Bioinspiration and Biomimetics, provide a stepping stone on the path to using autonomous robots in an open environment to monitor and control fish behaviour.

In the future, water-based robots could potentially contribute to the protection of endangered animals and the control of pest species.

Rice, UCLA slash energy needs for next-generation memory

HOUSTON -- (June 7, 2012) -- Researchers from Rice University and UCLA unveiled a new data-encoding scheme this week that slashes more than 30 percent of the energy needed to write data onto new memory cards that use "phase-change memory" (PCM) -- a competitor to flash memory that has big backing from industry heavyweights.

The breakthrough was presented at the IEEE/ACM Design Automation Conference (DAC) in San Francisco by researchers from Rice University's Adaptive Computing and Embedded Systems (ACES) Laboratory.

'Nanocable' could be big boon for energy storage

HOUSTON -- (June 7, 2012) -- Thanks to a little serendipity, researchers at Rice University have created a tiny coaxial cable that is about a thousand times smaller than a human hair and has higher capacitance than previously reported microcapacitors.

All the colors of a high-energy rainbow, in a tightly focused beam

For the first time, researchers have produced a coherent, laser-like, directed beam of light that simultaneously streams ultraviolet light, X-rays, and all wavelengths in between.

One of the few light sources to successfully produce a coherent beam that includes X-rays, this new technology is the first to do so using a setup that fits on a laboratory table.

An international team of researchers, led by engineers from the NSF Engineering Research Center (ERC) for EUV Science and Technology, reports their findings in the June 8, 2012, issue of Science.
