The popular Wii gaming remote may offer radiologists a fun, alternative method to using a standard mouse and keyboard to navigate through patient images, according to a study performed at the New-York Presbyterian Hospital/Weill Cornell Medical Center in New York, NY. The remote may also offer radiologists relief from repetitive motion injuries as a result of using a mouse and keyboard.
A research team from Northeastern University and the National Institute of Standards and Technology (NIST) has discovered, serendipitously, that a residue of a process used to build arrays of titania nanotubes—a residue that wasn’t even noticed before this—plays an important role in improving the performance of the nanotubes in solar cells that produce hydrogen gas from water.
These days, chemical analysts are expected to track down even single molecules. To do this highly sensitive detective work, nano researchers have developed minute strings that resonate in characteristic fashion. If a molecule docks onto one of the strings, then it becomes heavier, and its oscillations become measurably slower. Until recently, however, such "nano-electromechanical systems", or NEMS, have been short of practical applications.
Copenhagen, Denmark, Thursday 23 April: The first identification of GP130 somatic activating mutations* in human tumours was announced today at EASL 2009, the Annual Meeting of the European Association for the Study of Liver Disease in Copenhagen, Denmark.
During these trying financial times, the cost of healthcare and how much we are willing to pay for it is at the top of our economic concerns. The financial value of pain has a wide ranging influence, affecting drug prices and injury compensation. But what about on an individual level — is it possible to place a value on our health, to prevent pain and suffering? University College London psychologists Ivo Vlaev and Nick Chater, and neuroscientists Ben Seymour and Raymond J. Dolan were interested in just how much money volunteers were willing to pay to avoid pain and discomfort.
In London, motorists pay a fee to drive into certain parts of the city during peak traffic hours, and the idea has been considered for implementation in New York as well. Now Dr. Itai Ater, an economist from Tel Aviv University's Faculty of Management, is suggesting that introducing "congestion pricing" at airports could save travellers time and airlines money.
BOULDER, Colo.-Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a technique for efficiently suppressing errors in quantum computers. The advance could eventually make it much easier to build useful versions of these potentially powerful but highly fragile machines, which theoretically could solve important problems that are intractable using today's computers.
A new study, led by Lucy Selman and colleagues from King's College London, has found that patients with incurable, progressive diseases and their family carers in sub-Saharan Africa often do not receive enough information about the patient's disease and its management, which impacts negatively on their ability to cope with illness. The results of the study have been published online by the BMJ today.
Scientists at the University of East Anglia (UEA) have created lip-reading computers that can distinguish between different languages.
Computers that can read lips are already in development but this is the first time they have been 'taught' to recognise different languages. The discovery could have practical uses for deaf people, for law enforcement agencies, and in noisy environments.
Led by Stephen Cox and Jake Newman of UEA's School of Computing Sciences, the groundbreaking research will be presented at a major conference in Taiwan on Wednesday April 22.
GALVESTON, Texas — According to a study by researchers at the University of Texas Medical Branch at Galveston, elderly Medicare recipients transitioning from outpatient to hospital settings were more likely to experience lapses in continuity of care in 2006 than 1996. The researchers ascribe part of the reduction in continuity of care to the increasing use of hospitalists, physicians who specialize in the care of hospitalized patients.
Computer engineers at Washington University in St. Louis are bringing the minimalist approach to medical care and computing by coupling USB-based ultrasound probe technology with a smartphone, enabling a compact, mobile computational platform and a medical imaging device that fits in the palm of a hand.
CHAMPAIGN, Ill. — Researchers at the University of Illinois have found a new way to make transistors smaller and faster. The technique uses self-assembled, self-aligned, and defect-free nanowire channels made of gallium arsenide.
PITTSBURGH—Researchers at Carnegie Mellon University's School of Computer Science have developed a new method for systematically identifying bugs in aircraft collision avoidance systems, high-speed train controls and other complex, computer-controlled devices, collectively known as cyber-physical systems (CPS).
PHILADELPHIA, PA – April 17, 2009. OptiNose today announced important new results from a Phase II trial of its novel nasal drug delivery device with fluticasone for the treatment of chronic rhinosinusitis. Patients in the active treatment group experienced significant improvements in nasal symptoms, nasal discomfort and sense of smell. There was also a highly significant and progressive reduction in nasal swelling.
