Smaller and more energy-efficient electronic chips could be made using molybdenite. In an article appearing online January 30 in the journal Nature Nanotechnology, EPFL's Laboratory of Nanoscale Electronics and Structures (LANES) publishes a study showing that this material has distinct advantages over traditional silicon or graphene for use in electronics applications.

ANN ARBOR, Mich.---A majority of African American men said they do not go to the doctor because visits are stressful and physicians don't give adequate information on how to make prescribed behavior or lifestyle changes, a new University of Michigan study shows.

When they did go, the majority of the 105 men questioned said they disliked the tone physicians used with them. When those men did visit the doctor, they said it was because they were seeking test results or their family encouraged them to go.

ANN ARBOR, Mich.---Some orthodontists may be exposing young patients to unnecessary radiation when they order 3-D X-ray imaging for simple orthodontic cases before considering traditional 2-D imaging, suggests a paper published by University of Michigan faculty.

There is ongoing debate in the orthodontic community over if and when to use cone beam computed tomography (CBCT) for orthodontic diagnosis and treatment planning, said Dr. Sunil Kapila, lead author of the paper and chair of the Department of Orthodontics and Pediatric Dentistry at the U-M School of Dentistry.

Princeton University engineers have developed a new laser sensing technology that may allow soldiers to detect hidden bombs from a distance and scientists to better measure airborne environmental pollutants and greenhouse gasses.

The rise of social media has allowed people to connect and re-connect with friends, colleagues and family from across the world. A new paper by University of Minnesota computer scientists in the College of Science and Engineering provides insights into how the analysis of our social networking interactions could discover things like the emergence or decline of leadership, changes in trust over time, and migration and mobility within particular communities online.

Many different aspects are involved in predicting high water and floods, such as the type of precipitation, wind, buildings and vegetation. The greater the number of variables included in predictive models, the better the prediction will be. However, the models will inevitably become increasingly more complex.

The 'smug marrieds' may have good reason to feel pleased with themselves as experts today confirm that long-term committed relationships are good for mental and physical health and this benefit increases over time.

In an editorial published by student BMJ, David and John Gallacher from Cardiff University say that on average married people live longer. They say that women in committed relationships have better mental health, while men in committed relationships have better physical health, and they conclude that "on balance it probably is worth making the effort."

Madison, WI January 27, 2011 – Soybean production has continued to increase in the Northeast United States with more and more first time growers planting the crop and many experienced growers planting alongside corn crops. To save on time and expenses, some farmers plant soybeans with a corn planter in 30-inch rows instead of 7.5-inch rows with the regularly used grain drill.

Just touching it slightly with the tips of your fingers is enough. You can effortlessly write, navigate, open menu windows or rotate images on touchscreens. Within fractions of a second your touch is translated into control commands that a computer understands. At first glance, this technology borders on the miraculous, but in real life this mystery just is a wafer-thin electrode under the glass surface of the display made of indium-tin-oxide, ITO.

The baby and toddler phase is not necessarily the happiest time in life. Satisfaction with life and one's relationship can deteriorate for most new mothers. However, those who are satisfied with their relationship during pregnancy are most satisfied three years later.

This comes from a recent study from the Norwegian Institute of Public Health. The study includes 60,000 Norwegian women with small children.

CORVALLIS, Ore. – Little girls growing up in western society are expected to be neat and tidy – "all ribbon and curls" – and one researcher who studies science and gender differences thinks that emphasis may contribute to higher rates of certain diseases in adult women.

The link between increased hygiene and sanitation and higher rates of asthma, allergies and autoimmune disorders is known as the "hygiene hypothesis" and the link is well-documented. Yet the role of gender is rarely explored as part of this phenomenon.

Researchers from the universities of Navarra and Las Palmas de Gran Canaria have demonstrated that the ingestion of trans-fats and saturated fats increase the risk of suffering depression, and that olive oil, on the other hand, protects against this mental illness.
