Fear plays a major role in whether women decide to go for cancer screening or not, but healthcare providers underestimate how much women need to know and wrongly assume that they will ask for information if they want it.

Those are the two key findings from a study published in the June issue of the UK-based Journal of Advanced Nursing.

Bioremediation of industrial sites and petrochemical spillages often involves finding microbes that can gorge themselves on the toxic chemicals. This leaves behind a non-toxic residue or mineralized material. Writing in the International Journal of Environment and Pollution, researchers in China describe studies of a new microbe that can digest hydrocarbons.

CHICAGO --- If you are pregnant and your mate complains your frequent snoring is rattling the bedroom windows, you may have bigger problems than an annoyed, sleep-deprived partner.

A new study from researchers at the Northwestern University Feinberg School of Medicine has found that women who reported frequent snoring during their pregnancy were more likely to develop gestational diabetes -- a condition than can cause health problems for the mother and baby. The study also found pregnancy increases the likelihood that a woman will snore.

WESTCHESTER, Ill. – Body Mass Index (BMI) varies as a function of habitual sleep duration, according to a research abstract that will be presented on Thursday, June 11, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies.

Results indicate that twins who slept between 7 and 8.9 hours each night had a lower mean BMI (25.0 kg/m2) compared to those who regularly slept either more (25.2 kg/m2) or less (26.4 kg/m2) per night. The relationship between sleep duration and BMI remained after controlling for genetics and shared environment.

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.
