The strong winds of a tropical cyclone whip up the sea surface, driving ocean waves a dozen meters (about 40 feet) high. When one such ocean wave runs into another wave that has an equal period but is traveling in the opposite direction, the interaction produces low-frequency sound waves that can be detected thousands of kilometers away. Known as microbarom, the infrasound signals produced by interacting ocean surface waves have typical frequencies around 0.2 hertz. http://phys.org/news277452229.html Space & Earth Tue, 15 Jan 2013 08:10:01 EST news277452229 As ocean waves pass from deeper water into the shallow coastal regions, they begin to break, churning up the surf zone waters. At the edges of the crests of the breaking waves, horizontally-rotating eddies (vertical vortices) are generated, converting some of the waves' kinetic energy into turbulence. These horizontally-rotating eddies are an important mechanism for dispersing nutrients, larvae, bacteria, sediments, and other suspended objects along the coastline. http://phys.org/news277452098.html Space & Earth Tue, 15 Jan 2013 07:10:01 EST news277452098 In the fight against cancer, knowing the enemy's exact identity is crucial for diagnosis and treatment, especially in metastatic cancers, those that spread between organs and tissues. Now chemists led by Vincent Rotello at the University of Massachusetts Amherst have developed a rapid, sensitive way to detect microscopic levels of many different metastatic cell types in living tissue. Findings appear in the current issue of the journal ACS Nano. http://phys.org/news266765772.html Chemistry Thu, 13 Sep 2012 14:36:29 EST news266765772 Inspired by the twitching whiskers of common rats and Etruscan shrews, European researchers have developed rodent-like robots and an innovative tactile sensor system that could be used to help find people in burning buildings, make vacuum cleaners more efficient and eventually improve keyhole surgery. http://phys.org/news265551392.html Technology Thu, 30 Aug 2012 13:16:51 EST news265551392 Japanese researchers from the National Institute of Advanced Industrial Science and Technology (AIST), have developed an all-printed flexible pressure sensor in collaboration with Ajinomoto Co., Inc. http://phys.org/news264155856.html Technology Thu, 16 Aug 2012 10:00:31 EST news264155856 Much of the 6,200 metric tons of used nuclear fuel generated by U.S. power plants over the last 40 years is stored safely in giant stainless steel casks. Darryl Butt, a Boise State University professor, is part of a team researching whether it can be stored that way for at least 60 more. http://phys.org/news261386223.html Technology Fri, 13 Jul 2012 08:17:29 EST news261386223 The next generation of wind energy facilities in the United States may be built offshore where winds are stronger, floating platforms could be utilized, and links to power grids may already exist. http://phys.org/news248442874.html Technology Tue, 14 Feb 2012 11:54:48 EST news248442874 Scientists are reporting the development and successful tests in humans of a sensor array that can diagnose multiple sclerosis (MS) from exhaled breath, an advance that they describe as a landmark in the long search for a fast, inexpensive and non-invasive test for MS -- the most common neurological disease in young adults. Their report appears in the journal ACS Chemical Neuroscience. http://phys.org/news238859287.html Chemistry Wed, 26 Oct 2011 14:48:21 EST news238859287 (PhysOrg.com) -- iRobot is working on robots that have the brains of an Android tablet. The goal is an Android-based tablet that is able to see the world around it, hear input from humans, respond and think about the next task that needs to be done. These robots will be somewhere between the super-advanced military grade robots developed by organizations such as DARPA and the Roomba sitting under your sofa. This is good news that the goal to create these mid-range robots is one that they hope to achieve in our lifetime. http://phys.org/news224424582.html Electronics Thu, 12 May 2011 13:10:35 EST news224424582 University of Illinois chemists have developed a simple sensor to detect an explosive used in shoe bombs. It could lead to inexpensive, easy-to-use devices for luggage and passenger screening at airports and elsewhere. http://phys.org/news206717248.html Chemistry Tue, 19 Oct 2010 14:27:57 EST news206717248 MIT chemical engineers have built a sensor array that, for the first time, can detect single molecules of hydrogen peroxide emanating from a single living cell. http://phys.org/news187186641.html Nanotechnology Sun, 07 Mar 2010 13:00:08 EST news187186641 Researchers in Singapore are reporting development of a new electronic sensor that shows promise as a faster, less expensive, and more practical alternative than tests now used to detect DNA. Such tests are done for criminal investigation, disease diagnosis, and other purposes. The new lab-on-a-chip test could lead to wider, more convenient use of DNA testing, the researchers say. Their study is scheduled for the Sept. 2 issue of the Journal of the American Chemical Society. http://phys.org/news170502528.html Chemistry Wed, 26 Aug 2009 10:49:15 EST news170502528 (PhysOrg.com) -- A unique polymer that allows sensors to detect nerve agents and other toxic industrial chemicals in the air is now available to companies developing chemical detectors for emergency personnel, indoor air quality monitoring and other uses. http://phys.org/news159030307.html Chemistry Wed, 15 Apr 2009 16:05:42 EST news159030307
