A study in this week's New England Journal of Medicine potentially has significant implications for prenatal testing for major fetal chromosome abnormalities. The study found that in a head-to-head comparison of noninvasive prenatal testing using cell free DNA to standard screening methods, testing significantly reduced the rate of...
Water has been detected in the atmosphere of a planet outside our solar system with a new technique that could help researchers to learn how many planets with water, like Earth, exist throughout the universe. The astronomers detected the water in the atmosphere of a planet as massive as Jupiter that is orbiting the nearby star tau Boötis.
Stars, diamonds, circles. Rather than your bowl of Lucky Charms, these are three-dimensional cell cultures generated by a new digital microfluidics platform, the results of which have been published in Nature Communications this week by researchers at the University of Toronto. The tool, which can be used to study cells in cost-efficient, three-dimensional microgels, may hold the key to personalized medicine applications in the future.
A real-time hurricane analysis and prediction system that effectively incorporates airborne Doppler radar information may accurately track the path, intensity and wind force in a hurricane, according to Penn State meteorologists. This system can also identify the sources of forecast uncertainty.
Visual acuity is sharpest for rats and mice when the animals are looking down. Researchers have found that rodents can learn tasks in a fourth to a sixth of the usual number of repetitions when visual stimuli are projected onto the floor of the maze rather than onto the walls. Findings are reported in the Journal of Visualized Experiments.
Beating cancer is all about early detection, and new research from the University of South Carolina is another step forward in catching the disease early. A team of chemists is reporting a new way to detect just a few lurking tumor cells, which can be outnumbered a billion to one in the bloodstream by healthy cells.
A bright supernova discovered only six weeks ago in a nearby galaxy is provoking new questions about the exploding stars that scientists use as their main yardstick for measuring the universe. Called SN 2014J, the glowing supernova was discovered by a professor and his students in the United Kingdom on Jan. 21, about a week after the stellar explosion first became visible as a pinprick of light in its galaxy.
Formation detection could be new tool for visually summarizing a game. An automated analysis by Disney Research Pittsburgh of team formations used during an entire season of professional soccer provides further evidence that visiting teams are less successful than home teams because they play conservatively, not because of a mythical home advantage.
Associated with unhappy visits to the dentist, “cavity” means something else in the branch of physics known as optics .Put simply, an optical cavity is an arrangement of mirrors that allows beams of light to circulate in closed paths. Engineers are developing an optical “nanocavity” to boost light absorption in semiconductors; it could improve solar cells, cameras and more.
All modes of sensory perception are based on communication between nerve cells. Both the response to the primary stimulus and the transmission of the resulting signal depend on the function of specialized receptor proteins that are associated with the surface membranes of neurons. However, Dirk Trauner has helped develop a method which enables all types of neuroreceptors to be controlled by light.
Smart devices - such as tablets and phones - increasingly are an essential part of everyday life on Earth. The same can be said for life off-planet aboard the International Space Station. From astronaut tweets to Google+ Hangouts, our reliance on these mobile and social technologies means equipment and software upgrades are an everyday occurrence - like buying a new pair of shoes to replace a pair of well-worn ones.
Standing in a full-body scanner at an airport isn't fun, and the process adds time and stress to a journey. Researchers now report in ACS' The Journal of Physical Chemistry Letters a more precise and direct method for using that "terahertz" (THz) technology to detect explosives from greater distances. The advance could ultimately lead to detectors that survey a wider area of an airport without the need for full-body scanners.
There is a supernova explosion designated SN 2014J in the galaxy M82. At a distance of approximately 11.5 million light-years from Earth it is the closest supernova of its type discovered in the past few decades. The explosion is categorized as a Type Ia supernova....
Starwood Hotels & Resorts wants to replace traditional plastic room keys with smartphone apps. The app would allow guests to skip check-in and go straight to their rooms. The idea of keyless entry is nothing new — see: keyless vehicle entry, industrial security, office ID cards, etc. — but applying it to hotels is certainly novel.
In the last year or two, you may have had some moments — during elections, sporting events, or weather incidents — when you found yourself sending out a flurry of messages on social media sites such as Twitter. You are not alone, of course: Such events generate a huge volume of social-media activity. Now a new study shows that social-media messages grow shorter as the volume of activity rises at these particular times.
