Ancient gardens are the stuff of legend, from the Garden of Eden to the Hanging Gardens of Babylon. Now researchers at Tel Aviv University, in collaboration with Heidelberg University in Germany, have uncovered an ancient royal garden at the site of Ramat Rachel near Jerusalem, and are leading the first full-scale excavation of this type of archaeological site anywhere in the pre-Hellenistic Levant.
Members of the public could form the backbone of powerful new mobile internet networks by carrying wearable sensors.
According to researchers from Queen's University Belfast, the novel sensors could create new ultra high bandwidth mobile internet infrastructures and reduce the density of mobile phone base stations.
The engineers from Queen's renowned Institute of Electronics, Communications and Information Technology (ECIT), are working on a new project based on the rapidly developing science of body centric communications.
The equipment, based on automatic camera surveillance and wireless network connection, is handily located on a mobile trailer unit. The police are thus able to monitor traffic and impose penalties for violations more comprehensively and fairly. The monitoring information is gathered into a common database available to the police, road operators and environmental authorities. A pilot system has been launched in Tampere enabling the police to test the equipment.
Cincinnati, OH, October 28, 2010 -- The American Academy of Pediatrics (AAP) recommends that parents limit combined screen time from television, DVDs, computers, and video games to 2 hours per day for preschool-age children. In a study soon to be published in The Journal of Pediatrics, researchers found that many children are exposed to screen time both at home and while at child care, with 66% exceeding the recommended daily amount.
Medical schools and clinics could boost the number of primary care physicians in medically underserved areas by selecting and encouraging students from these communities, who often exhibit a strong sense of responsibility for and identification with the people there, according to a new study by UCLA researchers and colleagues published in the current issue of the American Journal of Public Health.
Extending its 26-year tradition of innovative quantum voltage standards, researchers at the National Institute of Standards and Technology (NIST) have begun shipping a new 10-volt standard to users around the world. The programmable system measures both direct current (DC) and alternating current (AC) voltages.NIST AC/DC 10-volt standard chip.
Better psychological and spiritual support, improved planning of care and stronger relationships with physicians are necessary to improve end-of-life care in Canada, according to a study by a Queen's University professor.
"High quality end-of-life care should be the right of every Canadian," says professor of Medicine and Epidemiology Daren Heyland, who is also a researcher at Kingston General Hospital. "But it's not always happening. We know from international studies that Canada ranks ninth in the world in terms of quality of care provided at the end of life."
Scientists are reporting development of a new approach for dealing with offensive household and other odors — one that doesn't simply mask odors like today's room fresheners, but eliminates them at the source. Their research found that a deodorant made from nanoparticles — hundreds of times smaller than peach fuzz — eliminates odors up to twice as effectively as today's gold standard. A report on these next-generation odor-fighters appears in ACS' Langmuir, a bi-weekly journal.
Mention the "A-Train" and most people probably think of the jazz legend Billy Strayhorn or perhaps New York City subway trains — not climate change. However, it turns out that a convoy of "A-Train" satellites has emerged as one of the most powerful tools scientists have for understanding our planet's changing climate.
Duke University and University of North Carolina (UNC) researchers report in the November issue of Arthritis Care & Research that narcotics and diagnostic testing are overused in treating chronic neck pain. Their findings indicate clinicians may overlook more effective treatments for neck pain, such as therapeutic exercise. According to reviews cited in the study, evidence to support the effectiveness of therapeutic exercise in treating chronic neck pain is good, yet only 53% of subjects were prescribed such exercise.
Professor Zhipeng Wu has invented a portable scanner based on radio frequency technology, which is able to show in a second the presence of tumours – malignant and benign – in the breast on a computer.
Using radio frequency or microwave technology for breast cancer detection has been proven by researchers in the US, Canada and UK. However, up to now, it can take a few minutes for an image to be produced, and this had to be done in a hospital or specialist care centre.
Cutting surveillance for mosquito-borne diseases would likely translate into an exponential increase in both the number of human cases and the health costs when a disease outbreak occurs, according to an analysis by Emory University.
The Public Library of Science (PLoS) publishes the research, led by Emory disease ecologist Gonzalo Vazquez-Prokopec, Oct. 26.
"Our analysis shows that halting mosquito surveillance can increase the management costs of epidemics by more than 300 times, in comparison with sustained surveillance and early case detection," Vazquez-Prokopec says.
Older adults who survived severe sepsis were more likely to develop substantial cognitive impairment and functional disability, according to a study in the October 27 issue of JAMA.
Hundreds of thousands of patients endure severe sepsis each year in the United States, according to background information in the article. "Although severe sepsis is the most common non-cardiac cause of critical illness, the long-term impact of severe sepsis on cognitive and physical functioning is unknown," the authors write.
Type 1 diabetes (T1D), formerly known as juvenile diabetes, is a multifactorial disease of complex etiology characterized by the autoimmune destruction of pancreatic beta cells. In addition to genetic susceptibility, it is generally accepted that environmental factors play important roles in triggering disease, with virus infection having perhaps the strongest association. Multiple viral infections including cytomegalovirus, mumps, rubella, enteroviruses, and parvovirus have all been associated with human T1D.
SAN DIEGO -- Prostate cancer patients who receive intensity modulated radiation therapy (IMRT) are less apt to suffer serious gastrointestinal complications following their treatment than those who receive three-dimensional conformal radiotherapy (CRT), according to new research from the University of Pennsylvania School of Medicine. The study, which will be presented Nov.
