Computer technology has transformed the way we live, but as consumers expect ever more from their devices at faster speeds, personal computers as well as larger electronic systems can overheat. This can cause them to slow down, or worse, completely shut down. Now researchers are reporting in the ACS journal Industrial & Engineering Chemistry Research that liquids containing nanoparticles could help devices stay cool and keep them running.

Also notable, the team's technique could operate through dynamic scattering. "Most scattering media of interest, like biological tissue, are dynamic in the sense that the scatter centers continuously change their positions with time -- meaning that the speckle patterns are 'in motion.' This is ideal for some applications because monitoring the changes of the speckle can reveal information about the sample, but the drawback is that it's a major nuisance to transmit or get images," Lancis pointed out.
HOUSTON, July 1, 2014 – There are a handful of naturally occurring materials, known as piezoelectric materials, that generate electricity if you bend, stretch or apply another mechanical force to them, and vice versa – if you apply a voltage across them, they'll deform accordingly. These materials are currently the subject of intense research for their potential applications in energy harvesting, artificial muscles and sensors, among others.
PULLMAN, Wash. - Washington State University has developed a wireless network on a computer chip that could reduce energy consumption at huge data farms by as much as 20 percent.
Theorists propose a way to make superconducting quantum devices such as Josephson junctions and qubits, atom-by-atom, inside a silicon crystal. Such systems could combine the most promising aspects of silicon spin qubits with the flexibility of superconducting circuits. The researcher's results have now been published in Nature Communications (1).
Li Haijun and fellow researchers at Minzu University of China, in Beijing, conducted a series of geometric morphometric analyses of the contours of the side face and variations in the Tu and Zang (Tibetan) ethnic minorities from Qinghai Province, in northwestern China.
Their study, entitled "Morphometric analysis of the Chinese facial profile: Contours of the side face and variations in the Tu and Zang ethnic minorities", was published (in Chinese) in the Chinese Science Bulletin, 2014, Vol 59(16).
CORVALLIS, Ore. – Could playing video games help people understand and address global sustainability issues such as pollution, drought or climate change? At least two researchers believe so, outlining their argument in a concept paper published in the journal First Monday.
Video games have the potential to educate the public and encourage development of creative solutions to social, economic and environmental problems, said Oregon State University's Shawna Kelly, one of the two authors of the article.
CAMBRIDGE, Mass-- Whenever there is a major spill of oil into water, the two tend to mix into a suspension of tiny droplets, called an emulsion, that is extremely hard to separate — and that can cause severe damage to ecosystems. But MIT researchers have discovered a new, inexpensive way of getting the two fluids apart again.
Experiments aimed at devising new types of photodetectors have been triggered by the increasing use of optoelectronic devices in personal electronics, cameras, medical equipment, computers and by the military. Professor Zhao Kun and co-researchers at the State Key Laboratory of Petroleum Resource and Prospecting, part of the China University of Petroleum in Beijing, have proposed a new type of infrared photodetector.

Scientists don't fully understand how 'plastic' solar panels work, which complicates the improvement of their cost efficiency, thereby blocking the wider use of the technology. However, researchers at the University of Montreal, the Science and Technology Facilities Council, Imperial College London and the University of Cyprus have determined how light beams excite the chemicals in solar panels, enabling them to produce charge.
Do not fold, spindle or mutilate. Those instructions were once printed on punch cards that fed data to mainframe computers. Today's smart phones process more data, but they still weren't built for being shoved into back pockets.
In the quest to build gadgets that can survive such abuse, engineers have been testing electronic systems based on a new materials that are both flexible and switchable – that is, capable of toggling between two electrical states, on-off, one-zero, the binary commands that can program all things digital.
Munich, 1 July 2014: While the majority of younger women are aware of egg freezing as a technique of fertility preservation and consider it an acceptable means of reproductive planning, only one in five would consider it appropriate for them, according to the results of an internet survey performed in the UK and Denmark.
The lifestyle altering effects of westernisation could be responsible for the high prevalence of obesity, and associated health risks in sub-Saharan Africa, researchers have found.
The study, published in PLOS ONE, by a team from the University of Warwick Medical School found that over one in five women in Nigeria were reported to be overweight or obese, with this statistic increasing among demographics with improved social and economic indicators.
A relic from long before the age of supercomputers, the 169-year-old math strategy called the Jacobi iterative method is widely dismissed today as too slow to be useful. But thanks to a curious, numbers-savvy Johns Hopkins engineering student and his professor, it may soon get a new lease on life.
