U of I study: Couples, pay attention to your relationship work ethic

URBANA, Ill. – Is a date with your partner as important to you as a meeting at work? A University of Illinois study recommends that couples develop a relationship work ethic that rivals—or at least equals—their professional work ethic. "When people enter the workplace, they make an effort to arrive on time, be productive throughout the day, listen attentively to co-workers and supervisors, try to get along with others, and dress and groom themselves to make a good impression," said Jill R. Bowers, a researcher in the U of I's Department of Human and Community Development. ...

Self-employment growth does not bank on access to capital

An entrepreneurial climate is more important than access to financing and banks in encouraging self-employment growth, according to rural economists. "Because people who get laid off may end up working for themselves, self-employment can be a good news, bad news situation," said Stephan Goetz, professor of agricultural and regional economics, Penn State, and director of the Northeast Regional Center for Rural Development. "However, the self-employed do tend to support other nearby businesses and that can lead to employment growth and income growth across the county." The ...

A step closer to a photonic future

WASHINGTON, Feb. 19–The future of computing may lie not in electrons, but in photons – that is, in microprocessors that use light instead of electrical signals. But these so-called photonic devices are typically built using customized methods that make them difficult and expensive to manufacture. Now, engineers have demonstrated that low power photonic devices can be fabricated using standard chip-making processes. They have achieved what the researchers dub a major milestone in photonic technology. The work will be presented at this year's OFC Conference and Exposition, ...

Infants with leukemia inherit susceptibility

Babies who develop leukemia during the first year of life appear to inherit an unfortunate combination of genetic variations that can make the infants highly susceptible to the disease, according to a new study at Washington University School of Medicine in St. Louis and the University of Minnesota. The research is available online in the journal Leukemia. Doctors have long puzzled over why it is that babies just a few months old sometimes develop cancer. As infants, they have not lived long enough to accumulate a critical number of cancer-causing mutations. "Parents ...

Clouds seen circling supermassive black holes

Astronomers see huge clouds of gas orbiting supermassive black holes at the centers of galaxies. Once thought to be a relatively uniform, fog-like ring, the accreting matter instead forms clumps dense enough to intermittently dim the intense radiation blazing forth as these enormous objects condense and consume matter, they report in a paper to be published in the Monthly Notices of the Royal Astronomical Society, available online now. Video depicting the swirling clouds is posted to YouTube http://youtu.be/QA8nzRkjOEw Evidence for the clouds comes from records collected ...

Better cache management could improve chip performance, cut energy use

Computer chips keep getting faster because transistors keep getting smaller. But the chips themselves are as big as ever, so data moving around the chip, and between chips and main memory, has to travel just as far. As transistors get faster, the cost of moving data becomes, proportionally, a more severe limitation. So far, chip designers have circumvented that limitation through the use of "caches" — small memory banks close to processors that store frequently used data. But the number of processors — or "cores" — per chip is also increasing, which makes cache management ...

When faced with a hard decision, people tend to blame fate

Life is full of decisions. Some, like what to eat for breakfast, are relatively easy. Others, like whether to move cities for a new job, are quite a bit more difficult. Difficult decisions tend to make us feel stressed and uncomfortable – we don't want to feel responsible if the outcome is less than desirable. New research suggests that we deal with such difficult decisions by shifting responsibility for the decision to fate. The findings are published in Psychological Science, a journal of the Association for Psychological Science. "Fate is a ubiquitous supernatural ...

Advance in energy storage could speed up development of next-gen electronics

Electronics are getting smaller all the time, but there's a limit to how tiny they can get with today's materials. Researchers now say, however, that they have developed a way to shrink capacitors — key components that store energy — even further, which could accelerate the development of more compact, high-performance next-gen devices. The study appears in the journal ACS Nano. Takayoshi Sasaki and colleagues point out that many recent improvements have already downsized capacitors significantly. But current technology has almost reached its limit in terms of materials ...

Special air filter blocks small particles called UFPs from getting inside cars

While taking in the scenery during long road trips, passengers also may be taking in potentially harmful ultrafine particles (UFPs) that come into the car through outdoor air vents. Closing the vents reduces UFPs, but causes exhaled carbon dioxide to build up. Now, scientists report in the ACS journal Environmental Science & Technology that installing a newly developed high-efficiency cabin air filter (HECA) could reduce UFP exposure by 93 percent and keep carbon dioxide levels low. Yifang Zhu and Eon Lee explain that most modern cars come with cabin air filters, but ...
