Tiny particles are pivotal to climate change, public health, and nanotechnology. A significant fraction of these particles are aspherical, yet scientists must routinely assume the particles are spherical to interpret many measurements of particle properties. To determine the true shape of particles, experts at Pacific Northwest National Laboratory and Imre Consulting devised SPLAT II, a single particle mass spectrometer that provides extremely precise particle measurements. http://www.physorg.com/news171641601.html Physics Tue, 08 Sep 2009 17:20:01 EST news171641601 (PhysOrg.com) -- The world's most powerful particle accelerator, the Large Hadron Collider (LHC), could be used to test the principles behind hyperdrive, a possible future form of spacecraft propulsion that could drive spacecraft at a good fraction of the speed of light. http://www.physorg.com/news174293159.html Physics Fri, 09 Oct 2009 07:49:14 EST news174293159 Superstring theory aims to explain the laws of physics from extremely small strings in various states. Theoretical superstring theory is therefore normally not considered to be particularly relevant for practical particle physics experiments. http://www.physorg.com/news176125202.html Physics Fri, 30 Oct 2009 12:42:37 EST news176125202 The world's biggest atom-smasher, shut down after its inauguration in September 2008 amid technical faults, restarted on Friday, a spokesman for the European Organisation for Nuclear Research said. http://www.physorg.com/news177951527.html Physics Fri, 20 Nov 2009 15:00:46 EST news177951527 Limit values for fine dust emissions are based on total particle weight. It is the ultra-fine particles, however, that are particularly harmful to health. A new technique separates them by size and identifies their composition -- directly where they arise. http://www.physorg.com/news173965788.html Technology Mon, 05 Oct 2009 12:50:41 EST news173965788 (PhysOrg.com) -- At a recent physics seminar at the Department of Energy`s Fermi National Accelerator Laboratory, Fermilab physicist Pat Lukens of the CDF experiment announced the observation of a new particle, the Omega-sub-b (Ωb). The particle contains three quarks, two strange quarks and a bottom quark (s-s-b). It is an exotic relative of the much more common proton and has about six times the proton`s mass. http://www.physorg.com/news165491925.html Physics Mon, 29 Jun 2009 10:59:17 EST news165491925 (PhysOrg.com) -- A new type of optical particle trap can be used to manipulate bacteria, viruses and other particles on a chip as part of an integrated optofluidic platform. The optical trap is the latest innovation from researchers at the Jack Baskin School of Engineering at the University of California, Santa Cruz, who are developing new sensor technology for biomedical analysis and other applications. http://www.physorg.com/news165594497.html Nanotechnology Tue, 30 Jun 2009 15:28:51 EST news165594497 (PhysOrg.com) -- Even if you are not a cook, you might have wondered why a pinch of flour (or any small particles) thrown into a bowl of water will disperse in a dramatic fashion, radiating outward as if it was exploding. Pushpendra Singh, PhD, a mechanical engineering professor at NJIT who has studied and written about the phenomenon, has not only thought about it, but can explain why. http://www.physorg.com/news177616622.html Physics Mon, 16 Nov 2009 18:30:05 EST news177616622 (PhysOrg.com) -- A chemist at the University of Wisconsin-Milwaukee (UWM) has developed a kind of invisible fence for trapping and controlling particles as small as a single virus or large protein. http://www.physorg.com/news169754920.html Nanotechnology Mon, 17 Aug 2009 19:20:02 EST news169754920 Real-life particles released by car brake pads can harm lung cells in vitro. Researchers writing in BioMed Central's open access journal Particle and Fibre Toxicology found that heavy braking, as in an emergency stop, caused the most damage, but normal breaking and even close proximity to a disengaged brake resulted in potentially dangerous cellular stress. http://www.physorg.com/news177918969.html Medicine & Health Fri, 20 Nov 2009 06:30:01 EST news177918969 (PhysOrg.com) -- The Milky Way, like many other galaxies, is thought to be embedded in massive, lumpy amounts of dark matter that release gamma rays and other emissions. Although at first these emissions seem too faint to detect, recent observations have shown that they may be stronger than previously thought. In a new study, scientists have developed a model that predicts that gamma rays from hundreds of dark matter clumps should be detectable by the Fermi satellite that was launched in June 2008. http://www.physorg.com/news169121408.html Physics Mon, 10 Aug 2009 11:10:36 EST news169121408 (PhysOrg.com) -- A consortium led by UC Davis physics professor Robert Svoboda will design the world's largest neutrino detector under a $4.4 million contract recently awarded by the National Science Foundation. http://www.physorg.com/news174731920.html Physics Wed, 14 Oct 2009 09:49:21 EST news174731920 (PhysOrg.com) -- Scientists drew fittingly from Roman mythology when they named a unique class of miniscule particles after the god Janus, who is usually depicted as having two faces looking in opposite directions. http://www.physorg.com/news169312269.html Nanotechnology Wed, 12 Aug 2009 16:11:55 EST news169312269 (PhysOrg.com) -- The LHC (Large Hadron Collider) is once again colder than deep space as it is prepared for experiments to resume in late November. http://www.physorg.com/news175243758.html Physics Tue, 20 Oct 2009 09:20:01 EST news175243758 (PhysOrg.com) -- Functionalized nano- and microscale particle systems have become a key component in biomedical applications, from drug delivery to prosthetics. Their small size and potential for modification and functionalization make them ideal for performing specific tasks within the human body. http://www.physorg.com/news172320850.html Nanotechnology Wed, 16 Sep 2009 12:10:04 EST news172320850
