A new microscope that views the subatomic universe -- the first of its kind in the world -- is being built for the University of Victoria, Canada, in collaboration with Hitachi High-Technologies. http://www.physorg.com/news166981239.html Nanotechnology Thu, 16 Jul 2009 16:41:18 EST news166981239 A new miniature, hand-held microscope may allow more precise removal of brain tumors and an easier recognition of tumor locations during surgery. http://www.physorg.com/news177178774.html Medicine & Health Wed, 11 Nov 2009 16:30:03 EST news177178774 Collaborative users from the Advanced Photon Source at the Argonne National Laboratory, working with the Electronic & Magnetic Materials & Devices Group, have found a controllable way to modify the surfaces of pristine Nb-doped SrTiO3 (Nb:STO) at the nanoscale. http://www.physorg.com/news176573506.html Nanotechnology Wed, 04 Nov 2009 16:30:03 EST news176573506 (PhysOrg.com) -- Quantum mechanics could help build ultra-high-resolution electron microscopes that won't destroy living cells, according to MIT electrical engineers. http://www.physorg.com/news174035443.html Physics Tue, 06 Oct 2009 08:12:08 EST news174035443 (PhysOrg.com) -- By building a tiny microscope small enough to be carried around on a rats' head, scientists at the Max Planck Institute for Biological Cybernetics in Tübingen, Germany, have found a way to study the complex activity of many brain cells simultaneously while animals are free to move around. http://www.physorg.com/news176455156.html Biology Tue, 03 Nov 2009 08:20:01 EST news176455156 Using a microscope the size of a football field, researchers from The University of Western Ontario are studying why some insects can survive freezing, while others cannot. http://www.physorg.com/news180350816.html Biology Fri, 18 Dec 2009 09:27:47 EST news180350816 (PhysOrg.com) -- David Cox, a scientist in the Quantum Detection group at the National Physical Laboratory in the UK, is an expert in nanofabrication techniques. Recently, using the tools of his trade and a bit of humor, he has created his latest masterpiece: the world's smallest snowman, which measures just 0.01 mm across (about one-fifth the width of a human hair). http://www.physorg.com/news179153163.html Nanotechnology Fri, 04 Dec 2009 12:46:35 EST news179153163 Researchers at the National Cancer Center in Japan have developed a system for detecting 70 percent of postoperative stomach cancer relapses, according to sources. http://www.physorg.com/news173970234.html Medicine & Health Mon, 05 Oct 2009 14:20:02 EST news173970234 A doctoral student at the research center Forschungszentrum Dresden-Rossendorf (Germany) suggests interpreting the images generated by Kelvin probe force microscopy in a new way. She recently published her insights in the journal Physical Review B. http://www.physorg.com/news172307152.html Nanotechnology Wed, 16 Sep 2009 08:06:33 EST news172307152 (PhysOrg.com) -- For the first time, IBM researchers in Zurich, Switzerland, have taken a 3D image of an individual molecule. Using an atomic force microscope, the researchers constructed a "force map" of pentacene, an organic molecule just 1.4 nanometers long. As the researchers explain, the technique is roughly analogous to how an x-ray machine images bones in the human body by looking through flesh. In this case, the scientists could look through the electron cloud and see the atomic backbone of the molecule. http://www.physorg.com/news170685108.html Nanotechnology Fri, 28 Aug 2009 13:34:27 EST news170685108 From the motion sensor to the computer chip - in many products of daily life components are used whose functioning is based on smallest structures of the size of thousandths - or even millionths - of millimetres. These micro and nano structures must be manufactured and assembled with the highest precision so that in the end, the overall system will function smoothly. http://www.physorg.com/news166093649.html Nanotechnology Mon, 06 Jul 2009 10:08:07 EST news166093649 The body is a battle zone. Cells constantly compete with one another for space and dominance. Though the manner in which some cells win this competition is well known to be the survival of the fittest, how stem cells duke it out for space and survival is not as clear. A study on fruit flies published in the October 2 issue of Science by Johns Hopkins researchers describes how stem cells win this battle by literally sticking around. http://www.physorg.com/news179171035.html Medicine & Health Fri, 04 Dec 2009 17:47:06 EST news179171035 (PhysOrg.com) -- On this day in 1989, IBM Fellow Don Eigler became the first person in history to move and control an individual atom. Shortly thereafter, on November 11 of that year, Eigler and his team used a custom-built microscope to spell out the letters IBM with 35 xenon atoms. This unprecedented ability to manipulate individual atoms signaled a quantum leap forward in in nanoscience experimentation and heralded in the age of nanotechnology. http://www.physorg.com/news173344987.html Nanotechnology Mon, 28 Sep 2009 08:23:35 EST news173344987 Scientists label cells with coloured or glowing chemicals to observe how basic cellular activities differ between healthy and cancerous cells. Existing techniques for labelling cells are either too slow or too toxic to perform on live cells. Now, a study reviewed by Philip Dawson, a member of Faculty of 1000 Biology and leading authority in chemistry and cell biology, describes a novel labelling technique that uses a chemical reaction to make live cancer cells light up quickly and safely. http://www.physorg.com/news173008489.html Medicine & Health Thu, 24 Sep 2009 11:20:01 EST news173008489 (PhysOrg.com) -- How do you handle the tiny components needed for constructing nanoscale devices? A European consortium has built two microrobotic demonstrators that can automatically pick up and install carbon nanotubes thousands of times thinner than a human hair. http://www.physorg.com/news169738415.html Nanotechnology Mon, 17 Aug 2009 14:34:14 EST news169738415
