ANN ARBOR, Mich.---A new application for the Android smartphone shows users and software developers how much power their applications are consuming. PowerTutor was developed by doctoral students and professors at the University of Michigan.

Battery-powered cell phones serve as hand-held computers and more these days. We run power-hungry applications while we depend on the phones to be available in emergencies.

A simple blood test corresponding to the follicular phase (days 3-14) of a normal menstrual cycle can aid in optimal scheduling of breast MRI exams in premenopausal women with irregular cycles — possibly reducing the number of repeat scans and non-diagnostic tests patients experience and providing clearer images on which doctors make their recommendations, according to a study published in the December issue of the American Journal of Roentgenology.

Surplus biomass from the production of flax shives, and generated from Brassica carinata, a yellow-flowered plant related to those which engulf fields in spring, can be used to produce bioethanol. This has been suggested by two studies carried out by Spanish and Dutch researchers and published in the journal Renewable and Sustainable Energy Reviews.

With the introduction of a single bacterial gene into yeast, researchers from Delft University of Technology in the Netherlands achieved three improvements in bioethanol production from agricultural waste material: 'More ethanol, less acetate and elimination of the major by-product glycerol' This week the invention was published in the scientific journal Applied and Environmental Microbiology.

At the 2009 Supercomputing Conference in Portland, Oregon (USA), the high-performance computer QPACE (QCD Parallel Computing on the Cell) was recognized today as the most energy-efficient supercomputer in the world. QPACE is at the head of the Green500 list, which provides a global ranking of energy-efficient supercomputers. QPACE was developed by an academic consortium of universities and research centers as well as the German IBM research and development center in Böblingen within the framework of a state-sponsored research association.

Purchasing prescription drugs in a three-month supply rather than a one-month supply has long been regarded as a way to reduce the cost of drugs for patients and third-party payers. New research from the University of Chicago quantifies the savings for the first time.

The increased computerization in U.S. hospitals hasn't made them cheaper or more efficient, Harvard researchers say, although it may have modestly improved the quality of care for heart attacks.

The findings, published in today's [Friday's] online edition of the American Journal of Medicine, contradict claims by President Obama and many lawmakers that health information technology (health IT), including electronic medical records, will save billions and help make reform affordable.

High irradiances of low-level laser therapy (LLLT) should not be used over melanomas. Researchers writing in the open access journal BMC Cancer studied the pain relieving, anti-inflammatory 'cold laser', finding that it caused increased tumour growth in a mouse model of skin cancer.

  • Prenatal alcohol exposure (PAE) has been linked to significant impairments in social skills.
  • Researchers have found that a social- skills intervention called Children's Friendship Training can lead to a decrease in hostile attributions or perceptions of children with PAE.

WEST LAFAYETTE, Ind. - Purdue University scientists have helped identify and group the genes thought to be responsible for cell wall development in maize, an effort that expands their ability to discover ways to produce the biomass best suited for biofuels production.

Most people would like to be able to charge their cell phones and other personal electronics quickly and not too often. A recent discovery made by UC San Diego engineers could lead to carbon nanotube-based supercapacitors that could do just this.

In recent research, published in Applied Physics Letters, Prabhakar Bandaru, a professor in the UCSD Department of Mechanical and Aerospace Engineering, along with graduate student Mark Hoefer, have found that artificially introduced defects in nanotubes can aid the development of supercapacitors.

OAK RIDGE, Tenn., Nov. 19, 2009 -- Sustainable farming, initially adopted to preserve soil quality for future generations, may also play a role in maintaining a healthy climate, according to researchers at the Department of Energy's Oak Ridge and Los Alamos national laboratories.

PROVIDENCE, RI – A commentary in the December issue of The Lancet Infectious Diseases brings to light the gaps in knowledge on the transmission of a common pathogen – the influenza virus – and its impact on decisions about how best to protect health care workers. Infectious diseases specialist Leonard Mermel, DO, medical director of infection control for Rhode Island Hospital, looks at the ongoing debate in light of the H1N1 pandemic, what past research tells us about the spread of influenza, and what is missing in the debate.

Obese patients are no more likely to have post-operative complications than those of average weight when undergoing robotic surgery to remove uterine fibroids, according to a study at Henry Ford Hospital.

Myomectomy is a procedure that removes uterine fibroids, leaving the uterus intact and preserving the ability for future pregnancies.

William Shakespeare, who knew a thing or two about words, advised that "An honest tale speeds best, being plainly told." But the exact meaning of plain language isn't always easy to find. Even simple words like "most" and "least" can vary greatly in definition and interpretation, and are difficult to put into precise numbers.
