PITTSBURGH--University of Pittsburgh researchers have shared their findings from three studies related to shale gas in a recent special issue of the journal Energy Technology, edited by Götz Veser, the Nickolas A. DeCecco Professor of Chemical and Petroleum Engineering in Pitt's Swanson School of Engineering.

Scientists from the Southwest University, Chongqing, China have found a new species and a new subspecies of cockroach. What makes these creepy crawlies distinctive from the cockroaches most of us know is that they don't infest human houses, on the contrary they prefer to live a hermit life drilling logs, hidden away from human eyes. The study was published in the open access journal ZooKeys.
Most parents are not surprised by the irregularity of a newborn infant's sleep patterns, but by six months or so many parents wonder if something is wrong with their baby or their sleeping arrangements if the baby is not sleeping through the night. Healthcare providers, specifically nurse practitioners, can help parents understand what "normal" sleep patterns are for their child, according to researchers.
Carnivorous plants catch and digest tiny animals in order and derive benefits for their nutrition. Interestingly the trend towards vegetarianism seems to overcome carnivorous plants as well. The aquatic carnivorous bladderwort, which can be found in many lakes and ponds worldwide, does not only gain profit from eating little animals but also by consuming algae and pollen grains. This results in survival in aquatic habitats where prey animals are rare, and in increased fitness if the animals and algae are caught in a well-balanced diet.
Researchers at the Mechanobiology Institute (MBI), National University of Singapore (NUS) have identified a novel mechanosensitive regulation of epithelial tube contraction. These findings are published on 19 December 2014 in Current Biology (doi: 10.1016/j.cub.2014.11.033).

Over the past decade, ocean acidification has received growing recognition not only in the scientific area. Decision-makers, stakeholders, and the general public are becoming increasingly aware of "the other carbon dioxide problem". It is time to reflect on the successes and deficiencies of ocean acidification research and to take a look forward at the challenges the fastest growing field of marine science is facing.
Bremerhaven/Germany, 18 December 2014. Ingestion of microplastic particles does not mechanically affect marine isopods. This was the result of a study by biologists at the North Sea Office of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) that was published recently in the journal Environmental Science and Technology. The study marks the launch of a series of investigations aimed at forming a risk matrix on the sensitivity of different marine species to microplastic pollution.
(MEMPHIS, Tenn. - DECEMBER 18, 2014) A study led by St. Jude Children's Research Hospital scientists has identified the population of white blood cells that tumors use to enhance growth and suppress the disease-fighting immune system. The results, which appear in the December 18 edition of the scientific journal Immunity, mark a turning point in cancer immunology and provide the foundation for developing more effective immunotherapies.
Hormone replacement therapy (HRT) is the most effective treatment for menopausal symptoms, in particular for younger women at the onset of the menopause, suggests a new review published today (19 December) in The Obstetrician & Gynaecologist (TOG).
The review highlights that menopausal symptoms, including hot flushes and night sweats are common, affecting around 70% of women for an average of 5 years but may continue for many years in about 10% of women.
Less than half of UK prescriptions for antipsychotic drugs are being issued to treat the serious mental illnesses for which they are mainly licensed, reveals research published in the online journal BMJ Open.
Instead, they may often be prescribed 'off label' to older people with other conditions, such as anxiety and dementia, despite the greater risk of potentially serious side effects in this age group, the findings indicate.
A Ugandan doctor, who contracted Ebola in Sierra Leone, survived after being flown to Germany for aggressive treatment involving a new drug under clinical development for vascular leakage [1]. Dr Timo Wolf and colleagues, from University Hospital Frankfurt in Germany, detail the successful intensive-care treatment the doctor received under biosafety level 4 conditions in an Article published in The Lancet.

An investigation into factors related to disparities of depression in young adults has found that higher parental education - which has a protective effect for white youth - can also increase the risk of depression for black youth. The MassGeneral Hospital for Children (MGHfC) study published online in the Journal of Pediatrics also found that, among high-socioeconomic-status black youth, greater perceptions of being discriminated against cancelled out the protective effects of parental education.
WINSTON-SALEM, N.C. - Dec. 18, 2014 - State and local enforcement of federal immigration laws can have an adverse impact on the use of health care services by immigrant Hispanics, according to a North Carolina-based study by Wake Forest Baptist Medical Center researchers.
The study, published in the Dec. 18 issue of the American Journal of Public Health, analyzed both birth records and information collected in focus groups and individual interviews.
Scientists from WCS (Wildlife Conservation Society), the Universidad Austral de Chile, the Blue Whale Center, the American Museum of Natural History (AMNH), NOAA, and other organizations are examining molecular clues to answer a big question: how many types of blue whales exist in the waters of the southeastern Pacific?
