Physicists Create World's Smallest Droplets
May 17, 2013 8:54 am | by Vanderbilt University | CommentsPhysicists may have created the smallest drops of liquid ever made in the lab. That possibility has been raised by the results of a recent experiment conducted by Vanderbilt physicist Julia Velkovska and her colleagues at the Large Hadron Collider, the world's largest and most powerful particle collider located at the European Laboratory for Nuclear and Particle Physics (CERN) in Switzerland.
New Method Proposed for Detecting Gravitational Waves from Ends of Universe
May 16, 2013 7:57 pm | by University of Nevada, Reno | CommentsRENO, Nev. – A new window into the nature of the universe may be possible with a device proposed by scientists at the University of Nevada, Reno and Stanford University that would detect elusive gravity waves from the other end of the cosmos. Their paper describing the device and process was published in the prestigious physics journal Physical Review Letters.
Can Math Models of Gaming Strategies Be Used to Detect Terrorism Networks?
May 16, 2013 3:55 pm | by Society for Industrial and Applied Mathematics | CommentsPhiladelphia, PA— The answer is yes, according to a paper in the SIAM Journal on Discrete Mathematics. In a paper published in the journal last month, authors Anthony Bonato, Dieter Mitsche, and Pawel Pralat describe a mathematical model to disrupt flow of information in a complex real-world network, such as a terrorist organization, using minimal resources.
Carbon in a Twirl: The Science Behind a Self-assembled Nano-carbon Helix
May 16, 2013 12:54 pm | by University of Vienna | CommentsNanomaterials exhibit unique properties that can only unfold when the structures of the material are very small – that is, at the nanoscale. In order to exploit these special properties such as, for example, specific quantum effects it is very important to produce predefined nanostructures in a controlled way and interpret the formation of their shape. Scientists try to understand how to initiate...

May 15, 2013 7:09 pm | by National Institute of Standards and Technology (NIST) | CommentsDetecting greenhouse gases in the atmosphere could soon become far easier with the help of an innovative technique* developed by a team at the National Institute of Standards and Technology (NIST), where scientists have overcome an issue preventing the effective use of lasers to rapidly scan samples.
Achieving Net-zero Energy Homes
May 15, 2013 7:09 pm | by National Institute of Standards and Technology (NIST) | CommentsChances are you know how many miles your car logs for each gallon or tankful of gas, but you probably have only a foggy idea of how much energy your house consumes, even though home energy expenditures often account for a larger share of the household budget.
NASA Completes First Part of Webb Telescope Eye Surgery
May 15, 2013 7:09 pm | by NASA/Goddard Space Flight Center | CommentsMuch like the inside of an operating room, in the clean room at NASA's Goddard Space Flight Center in Greenbelt, Md., engineers worked meticulously to implant part of the eyes of the James Webb Space Telescope. They scrubbed up and suited up to perform one of the most delicate performances of their lives. That part of the eyes, the MIRI, or Mid-Infrared Instrument, will glimpse the formation of...
Bombardment: Mars Camera Reveals Hundreds of Impacts Each Year
May 15, 2013 7:09 pm | by University of Arizona | CommentsScientists using images from NASA's Mars Reconnaissance Orbiter, or MRO, have estimated that the planet is bombarded by more than 200 small asteroids or bits of comets per year forming craters at least 12.8 feet (3.9 meters) across. Researchers have identified 248 new impact sites on parts of the Martian surface in the past decade
H1N1 Discovered in Marine Mammals
May 15, 2013 7:09 pm | by University of California - Davis | CommentsScientists at the University of California, Davis, detected the H1N1 (2009) virus in free-ranging northern elephant seals off the central California coast a year after the human pandemic began, according to a study published today, May 15, in the journal PLOS ONE. It is the first report of that flu strain in any marine mammal.
