PHILADELPHIA –- Engineers from the University of Pennsylvania, Sandia National Laboratories and Rice University have demonstrated the formation of interconnected carbon nanostructures on graphene substrate in a simple assembly process that involves heating few-layer graphene sheets to sublimation using electric current that may eventually lead to a new paradigm for building integrated carbon-based devices.

BERKELEY, CA – Graphene is the two-dimensional crystalline form of carbon, whose extraordinary electron mobility and other unique features hold great promise for nanoscale electronics and photonics. But there's a catch: graphene has no bandgap.

Berkeley -- Today's transistors and light emitting diodes (LED) are based on silicon and gallium arsenide semiconductors, which have fixed electronic and optical properties.

Now, University of California, Berkeley, researchers have shown that a form of carbon called graphene has an electronic structure that can be controlled by an electrical field, an effect that can be exploited to make tunable electronic and photonic devices.

HOUSTON - Four suspects often found at the scene of the crime in cancer are guilty of the initiation and progression of breast cancer in mice that are resistant to the disease, a team led by scientists at The University of Texas M. D. Anderson Cancer Center reports in the June edition of Cancer Cell.

WESTCHESTER, Ill. – According to a research abstract that will be presented on Wednesday, June 10, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies, older adults are able to retain better cognitive functioning during sleep deprivation than young adults.

COLUMBIA, Mo. – Osteoarthritis is commonly diagnosed in the late and irreversible stages, when treatment can only be expected to decrease pain and slow progression of disease. Because osteoarthritis is a widespread problem in dogs, horses and humans, doctors and veterinarians need a precise way to diagnose the disease early and accurately. Now, University of Missouri researchers are investigating potential biomarkers in dogs for early diagnosis of osteoarthritis, which could help identify patients at increased risk of developing osteoarthritis.

COLUMBUS, Ohio – The last thing most people in a bad love affair want to do is to read informational articles about romance. But people facing financial difficulties often choose to read articles which may help them cope with their money problems.

Those are some of the findings of a new study that aimed to discover whether people use the news media to escape from their problems or find information on how to cope with them.

ITHACA, N.Y. — Dairy genetics, nutrition, herd management and improved animal welfare over the past 60 years have resulted in a modern milk production system that has a smaller carbon footprint than mid-20th century farming practices, says a Cornell University study in the Journal of Animal Science (June 2009).

WESTCHESTER, Ill. – According to a research abstract that will be presented on Wednesday, June 10, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies, caffeine use prevents increased risk taking that occurs after several nights of total sleep deprivation.

WESTCHESTER, Ill. – According to a research abstract that will be presented on Wednesday, June 10, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies, older adults are able to retain better cognitive functioning during sleep deprivation than young adults.

WESTCHESTER, Ill. – Being stably married or gaining a partner is associated with better sleep in women than being unmarried or losing a partner, according to a research abstract that will be presented on Wednesday, June 10, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies.

Results show that women who were stably married or who had gained a partner during the eight years of the study had better sleep than women who were unmarried or who had lost a partner over the course of the study follow-up.

ANN ARBOR, Mich.---In places where young women outnumber young men, research shows the hemlines rise but the marriage rates don't because the young men feel less pressure to settle down as more women compete for their affections.

But when those men reach their 30s, the reverse is true and proportionately more older men are married in areas where women outnumber men.

Exposure to dioxins during pregnancy harms the cells in rapidly-changing breast tissue, which may explain why some women have trouble breastfeeding or don't produce enough milk, according to a University of Rochester Medical Center study.

Researchers believe their findings, although only demonstrated in mice at this point, begin to address an area of health that impacts millions of women but has received little attention in the laboratory, said corresponding author B. Paige Lawrence, Ph.D., associate professor of Environment Medicine and of Microbiology and Immunology at URMC.

DURHAM, N.C. -- It's a familiar scene in airports and train stations. Hands full with luggage, briefcase, laptop or coat and there's something you need to remember, like the level and row numbers where you parked your car in the deck. What do you do?

Instead of relying on your memory, or finding a place to put all your stuff down to find a pen and paper, wouldn't it be so convenient to simply write "level 4, row H" in the air and be able to retrieve it later?

CAMBRIDGE, Mass.--Countless hours are lost in traffic jams every year. Most frustrating of all are those jams with no apparent cause — no accident, no stalled vehicle, no lanes closed for construction.

Such phantom jams can form when there is a heavy volume of cars on the road. In that high density of traffic, small disturbances (a driver hitting the brake too hard, or getting too close to another car) can quickly become amplified into a full-blown, self-sustaining traffic jam.
