Like surfers on monster waves, electrons can ride waves of plasma to very high energies in a very short distance. Scientists have proven that plasma acceleration works. Now they're developing it as a way to dramatically shrink the size and cost of particle accelerators for science, medicine, industry, and myriad other uses. http://www.physorg.com/news177786729.html Physics Wed, 18 Nov 2009 17:13:04 EST news177786729 The practice of sterilizing medical tools and devices helped revolutionize health care in the 19th century because it dramatically reduced infections associated with surgery. Through the years, numerous ways of sterilization techniques have been developed, but the old mainstay remains a 130-year-old device called an autoclave, which is something like a pressure steamer. The advantage of the autoclave is that the unsterile tools can be packed into sealed containers and then processed, staying sealed and sterile after they are removed. http://www.physorg.com/news176997452.html Physics Mon, 09 Nov 2009 15:30:11 EST news176997452 (PhysOrg.com) -- Samsung Electronics has launched its latest autonomous robot vacuum cleaner, the Tango, which is capable of vacuuming hardwood floors, carpets, and even beds without human assistance. http://www.physorg.com/news176713649.html Electronics Fri, 06 Nov 2009 07:08:11 EST news176713649 (AP) -- Pest-control specialist Gene Scholes even gets bugged by them - legions of ladybugs lately swarming his rural Missouri home and other stretches across the country, exploiting gaps in door and window seals for cozier climes inside. http://www.physorg.com/news175412232.html Biology Thu, 22 Oct 2009 06:39:00 EST news175412232 (PhysOrg.com) -- Intrigued by NASA lunar missions in the 1990s which suggested the existence of ice within craters at the moon's poles, NASA scientist Dr. Edwin Ethridge and his team started cooking up a way to extract water from lunar soil. http://www.physorg.com/news175198787.html Space & Earth Mon, 19 Oct 2009 19:21:54 EST news175198787 A University of Michigan professor is developing an electric rocket thruster, NanoFET, that uses nanoparticle electric propulsion and enables spacecraft to travel faster and with less propellant than previous technology allowed. http://www.physorg.com/news175166748.html Nanotechnology Mon, 19 Oct 2009 10:40:02 EST news175166748 (PhysOrg.com) -- James Dyson, inventor of the bag-less vacuum cleaners has taken his invention one step further with the unveiling of the bladeless fan.

They successfully realized an exotic state, where, due to the laws of quantum mechanics, atoms align along a one-dimensional structure. A stable many-body phase with new quantum mechanical states is thereby produced even though the atoms are usually strongly attracted which would cause the system to collapse. The scientists report on their findings in the leading scientific journal Science. http://www.physorg.com/news171188983.html Physics Thu, 03 Sep 2009 14:00:02 EST news171188983 As the U.S. Navy minimizes its dependence on foreign oil, the Office of Naval Research (ONR) is a front runner in supporting and bringing forth innovative solutions to fuel consumption challenges. http://www.physorg.com/news170352387.html Space & Earth Mon, 24 Aug 2009 17:20:02 EST news170352387 Solar cells could soon be produced more cheaply using nanoparticle "inks" that allow them to be printed like newspaper or painted onto the sides of buildings or rooftops to absorb electricity-producing sunlight. http://www.physorg.com/news170331512.html Nanotechnology Mon, 24 Aug 2009 11:19:37 EST news170331512 Anyone who's vacationed in the mountains or lived on a farm knows that it's hard to get good internet access or a strong cell phone signal in a remote area.

While it's relatively easy to measure the speed of light in mediums made of one material, it's much more difficult to track light's speed through composite materials. Now, a new technique can determine the speed of light in composite materials by varying the pressure of light. http://www.physorg.com/news168281326.html Physics Sun, 02 Aug 2009 13:49:24 EST news168281326 The tubes that power X-ray machines are shrinking, improving the clarity and detail of their Superman-like vision.

The cockroaches were put in a variety of capsules to see how they would survive in different extreme environments, including cold temperatures (-40 degrees F), minimal atmosphere and high solar radiation. The capsules were first ground tested in a cold vacuum chamber to insure the chambers would survive the cold and near vacuum of space without bursting. The high-altitude balloon experiment came off without a hitch--all the cockroaches survived. http://www.physorg.com/news156101965.html Space & Earth Thu, 12 Mar 2009 18:40:49 EST news156101965 (PhysOrg.com) -- NASA's Lunar Reconnaissance Orbiter, or LRO, spacecraft was loaded on a truck Wednesday to begin its two-day journey to NASA's Kennedy Space Center in Florida.
