An algorithm that takes the patient's size into consideration can cut radiation dose by 41% in lumbar spine CT without compromising the diagnostic quality of the images, a new study shows.

The design brief for the VOI was to develop a two-wheel transporter that is as agile and affordable as a scooter and, at the same time, as safe and comfortable as a car. With its compact size and maneuverability, the two-wheel electric scooter is designed as a transporter for densely populated megacities and offers a comprehensive solution to metropolises where congested traffic is a major problem.
Sometimes cost saving comes in nanoscale packages.
A new procedure that thickens and thins fluid at the micron level could save consumers and manufacturers money, particularly for soap products that depend on certain molecules to effectively deal with grease and dirt. Researchers at the University of Washington published their findings online April 9 in the Proceedings of the National Academy of Sciences.
A new technique based on atomic force microscopy was developed at the Institute of Food Research to help 'read' information encoded in the gut lining.
The lining of our gut is an important barrier between the outside world and our bodies. Laid out, the gut lining would cover the area of a football pitch. It must let nutrients from our foods through, but prevent invasion by disease-causing bacteria, at the same time hosting the trillions of beneficial bacteria needed for proper digestion and immune function.
COLUMBUS, Ohio – American adults who prepare their own meals and exercise on the same day are likely spending more time on one of those activities at the expense of the other, a new study suggests.
The research showed that a 10-minute increase in food preparation time was associated with a lower probability of exercising for 10 more minutes – for both men and women. The finding applied to single and married adults as well as parents and those who have no children.
April 11, 2013, Fort Lauderdale, Fla. -- Changing the parameters used to deliver radiofrequency (RF) treatment greatly affects the size of the resulting heat lesion, researchers reported today in a study expected to deliver greater precision and more treatment options in interventional pain management. Results were presented at the 29th Annual Meeting of the American Academy of Pain Medicine.
ANN ARBOR—The explosive popularity of wireless devices—from WiFi laptops to Bluetooth headsets to ZigBee sensor nodes—is increasingly clogging the airwaves, resulting in dropped calls, wasted bandwidth and botched connections.
New software being developed at the University of Michigan works like a stoplight to control the traffic and dramatically reduce interference.
NEW ORLEANS, April 11, 2013 — Scientists today reported a discovery that could speed an emerging effort to replace ethanol in gasoline with a substantially better fuel additive called butanol, which some experts regard as "the gasoline of the future." Their report on this discovery, which holds potential to reduce the costs of converting ethanol factories to production of butanol, came at the 245th National Meeting & Exposition of the American Chemical Society, the world's largest scientific society.
The application of light for information processing opens up a multitude of possibilities. However, to be able to adequately use photons in circuits and sensors, materials need to have particular optical and mechanical properties. Researchers at the Karlsruhe Institute of Technology (KIT) have now for the first time used polycrystalline diamond to manufacture optical circuits and have published their results online in Nature Communications (DOI: 10.1038/ncomms2710).
On April 11thJoVE (Journal of Visualized Experiments) will publish a new video article by Dr. Aydogan Ozcan demonstrating how a cell phone camera can capture images from a fluorescent microscope and flow cytometer, which will make it possible for areas with limited resources to easily run tests such as checking for contaminated water and monitoring HIV positive patients.
For years, many scientists believed that forest tree lines on mountains everywhere would shift to higher elevations as the planet's temperature increased due to global warming.
It's not that simple, new University of Calgary research has shown.
Even in a warmer world, local geologic/geomorphic conditions – including slope steepness, exposure and soil depth – will limit trees being established and growing on mountainsides, the research found.
NEW ORLEANS, April 8, 2013 — Rice imported from certain countries contains high levels of lead that could pose health risks, particularly for infants and children, who are especially sensitive to lead's effects, and adults of Asian heritage who consume large amounts of rice, scientists said here today. Their research, which found some of the highest lead levels in baby food, was among almost 12,000 reports scheduled for the 245th National Meeting & Exposition of the American Chemical Society, the world's largest scientific society, which continues through Thursday.
Topological insulators (TIs) are an exciting new type of material that on their surface carry electric current, but within their bulk, act as insulators. Since the discovery of TIs about a decade ago, their unique characteristics (which point to potential applications in quantum computing) have been explored theoretically, and in the last five years, experimentally.
NEW ORLEANS, April 10, 2013 — In the latest achievement in efforts to see what may lie underneath the surface of great works of art, scientists today described the first use of an imaging technology like that used in airport whole-body security scanners to detect the face of an ancient Roman man hidden below the surface of a wall painting in the Louvre Museum in Paris.
NEW ORLEANS, April 10, 2013 — Tiny versions of the reflectors on sneakers and bicycle fenders that help ensure the safety of runners and bikers at night are moving toward another role in detecting bioterrorism threats and diagnosing everyday infectious diseases, scientists said today.
