Every cook knows the ingredients for making bread: flour, water, yeast, and time. But what chemical elements are in the recipe of our universe? http://www.physorg.com/news178996002.html Space & Earth Wed, 02 Dec 2009 17:13:29 EST news178996002 Researchers from the National Institute of Standards and Technology and the Naval Research Laboratory have developed a new way to introduce magnetic impurities in a semiconductor crystal by prodding it with a scanning tunneling microscope (STM). Detailed in a recent paper, this technique will enable researchers to selectively implant atoms in a crystal one at a time to learn about its electrical and magnetic properties on the atomic scale. http://www.physorg.com/news178978543.html Nanotechnology Wed, 02 Dec 2009 12:16:57 EST news178978543 An accidental discovery in a laboratory at Oregon State University has apparently solved a quest that over thousands of years has absorbed the energies of ancient Egyptians, the Han dynasty in China, Mayan cultures and more - the creation of a near-perfect blue pigment. http://www.physorg.com/news177606699.html Chemistry Mon, 16 Nov 2009 15:12:25 EST news177606699 (PhysOrg.com) -- A team of international researchers is the first to uncover the chemical composition and structure of a microelectronics element that is vital to producing ever smaller - and, thus, cheaper and faster - devices. http://www.physorg.com/news173985674.html Physics Mon, 05 Oct 2009 19:00:02 EST news173985674 In the first ecological study of its kind in the world, a Wake Forest University Baptist Medical Center researcher has uncovered the unique finding that groundwater and airborne manganese in North Carolina correlates with cancer mortality at the county level. http://www.physorg.com/news166455830.html Medicine & Health Fri, 10 Jul 2009 15:10:02 EST news166455830 Iron and manganese compounds, in addition to sulfate, may play an important role in converting methane to carbon dioxide and eventually carbonates in the Earth's oceans, according to a team of researchers looking at anaerobic sediments. These same compounds may have been key to methane reduction in the early, oxygenless days of the planet's atmosphere. http://www.physorg.com/news166367681.html Space & Earth Thu, 09 Jul 2009 14:15:22 EST news166367681 BOSTON--Higher selenium levels in the blood may worsen prostate cancer in some men who already have the disease, according to a study by researchers at Dana-Farber Cancer Institute the University of California, San Francisco. http://www.physorg.com/news165168421.html Medicine & Health Thu, 25 Jun 2009 17:07:35 EST news165168421 A species of bacteria, isolated from sediments deep under the Pacific Ocean, could provide a powerful clean-up tool for heavy metal pollution. http://www.physorg.com/news163394086.html Biology Fri, 05 Jun 2009 04:15:37 EST news163394086 Teams of scientists from Australia and the United States have used yeast and mammalian cells to discover a connection between genetic and environmental causes of Parkinson's disease. http://www.physorg.com/news154950981.html Medicine & Health Fri, 27 Feb 2009 09:57:03 EST news154950981 Researchers at UT Southwestern Medical Center have identified a protein that may help give Lyme disease its bite. The findings suggest that the bacterial protein, which aids in transporting the metal manganese, is essential for the bacterium that causes Lyme disease to become virulent. http://www.physorg.com/news153423735.html Medicine & Health Mon, 09 Feb 2009 17:43:08 EST news153423735 A connection between genetic and environmental causes of Parkinson's disease has been discovered by a research team led by Aaron D. Gitler, PhD, Assistant Professor in the Department of Cell and Developmental Biology at the University of Pennsylvania School of Medicine. Gitler and colleagues found a genetic interaction between two Parkinson's disease genes (alpha-synuclein and PARK9) and determined that the PARK9 protein can protect cells from manganese poisoning, which is an environmental risk factor for a Parkinson's disease-like syndrome. The findings appear online this week in Nature Genetics. http://www.physorg.com/news152720701.html Medicine & Health Sun, 01 Feb 2009 14:25:21 EST news152720701 Researchers at Newcastle University have taken a step forward in our understanding of how the fundamental building blocks of life are put together. http://www.physorg.com/news143900329.html Chemistry Wed, 22 Oct 2008 13:18:49 EST news143900329 Want more power and longer battery life for that cell phone, laptop, and digital music player? "Flower power" may be the solution. Chemists are reporting development of flower-shaped nanoparticles with superior electronic performance than conventional battery materials. These "nanoflowers" may power next-generation electronic devices, say the scientists in a report scheduled for the Oct. 8 issue of ACS' Nano Letters. http://www.physorg.com/news140701187.html Nanotechnology Mon, 15 Sep 2008 12:39:47 EST news140701187 Using a polymer that has both water-soluble and water-insoluble regions, a team of investigators from the Siteman Center of Cancer Nanotechnology Excellence has created a nanoparticle shaped like a bialy, a close relative of the bagel. http://www.physorg.com/news135964347.html Nanotechnology Tue, 22 Jul 2008 16:52:27 EST news135964347
