Molecules as circuits? Miniaturization of electronic devices Posted: 23 Jan 2014 04:55 AM PST Silicon-based electronics has certain limits, in the physical sense of the word: this type of circuit can never become "nano" because of the physical laws governing the flow of electrons. This imposes a halt to the process of miniaturization of electronic devices. One of the possible solutions is to use molecules as circuits, but their poor conduction capabilities make them unlikely candidates. There is, however, a possible way around this, which was investigated in a recent article.

Athletes' performance declines following contract years Posted: 22 Jan 2014 02:06 PM PST A professor has determined that the contract year performance boost is real, but they caution team managers and coaches that it might be followed by a post-contract performance crash -- a two-year pattern they call the "contract year syndrome."

Image or reality? Leaf research needs photos, lab analysis Posted: 22 Jan 2014 12:39 PM PST Every picture tells a story, but the story digital photos tell about how forests respond to climate change could be incomplete, according to new research. A new study shows that the peak in forest greenness as captured by digital pictures does not necessarily correspond to direct measures of peak chlorophyll content in leaves, which is an indicator of photosynthesis. The research has significant implications for how scientists use digital photos to study forest canopies.

White, green or black roofs? Report compares economic payoffs Posted: 22 Jan 2014 10:44 AM PST Looking strictly at the economic costs and benefits of three different roof types -- black, white and "green" (or vegetated) -- researchers have found in a new study that white roofs are the most cost-effective over a 50-year time span. While the high installation cost of green roofs sets them back in economic terms, their environmental and amenity benefits may at least partially mitigate their financial burden.

Live feed device monitors drugs in bloodstream in real time Posted: 22 Jan 2014 10:43 AM PST A device that can monitor the levels of specific drugs as they flow through the bloodstream may soon take the guesswork out of drug dosing and allow physicians to tailor prescriptions to their patients' specific biology. The biosensor combines engineering and biochemistry and has far-reaching potential.

Researcher finds anonymity makes a difference with online comments Posted: 22 Jan 2014 10:43 AM PST In a newly published study, a researcher outlines a significant correlation between anonymity and civility.

Joining up computer memory Posted: 22 Jan 2014 06:24 AM PST Innovative electrodes allow new computer memory technologies to be compatible with existing circuitry. The computing industry faces constant demands to provide faster access to data and reduce power consumption. As current memory systems cannot meet these demands indefinitely, it is essential to develop entirely new technologies. One strong contender is resistive random access memory (RRAM), which stores binary information by switching a dielectric material between conducting and non-conducting states.

New web-based course to prevent excessive weight gain may improve health in young adults Posted: 22 Jan 2014 06:14 AM PST The transition from adolescence to adulthood presents individuals with many challenges. Perhaps none are as important as those relating to health and quality of life. Being mildly to moderately overweight during this period substantially increases the likelihood of obesity at age 35 to 37. To prevent weight gain and promote healthy decision making, researchers developed a tailored, theory-based, web-delivered course to prevent excessive weight gain in young adults.
