Simpler way of making proteins could lead to new nanomedicine agents
— 23 Feb 2011 17:40 | HealthResearchers have developed a simple method of making short protein chains with spiral structures that can also dissolve in water, two desirable traits not often found together. Such…
Self-assembling structures open door to new class of materials
— 14 Jan 2011 16:41 | TechnologyResearchers at the University of Illinois and Northwestern University have demonstrated bio-inspired structures that self-assemble from simple building blocks: spheres…
National study shows CT screening of former, current smokers reduces lung cancer deaths
— 6 Nov 2010 16:00 | HealthA large national study finds that screening current or former heavy smokers with a CT scan can reduce deaths from lung cancers by 20 percent. One potential reason for the reduction…
Helical CT scans reduce lung cancer mortality by 20 percent compared to chest X-rays
— 5 Nov 2010 13:39 | HealthIn a major new study announced today by the National Cancer Institute, researchers including Brown University biostatistian Constantine Gatsonis and his colleagues found that screening…
Shape matters: The corkscrew twist of H. pylori enables it to 'set up shop' in the stomach
— 28 May 2010 12:24 | HealthThe bacterium Helicobacter pylori, which lives in the human stomach and is associated with ulcers and gastric cancer, is shaped like a corkscrew, or helix. For years researchers have…
Nanoscopic static electricity generates chiral patterns
— 2 Feb 2009 18:34 | ChemistryIn the tiny world of amino acids and proteins and in the helical shape of DNA, a biological phenomenon abounds. These objects are all chiral - they cannot exactly superimpose their…
Researchers control the assembly of nanobristles into helical clusters
— 9 Jan 2009 16:00 | TechnologyFrom the structure of DNA to nautical rope to distant spiral galaxies, helical forms are as abundant as they are useful in nature and manufacturing alike. Researchers at the Harvard…
Caltech scientists show function of helical band in heart
— 2 Dec 2008 13:32 | HealthScientists from the California Institute of Technology (Caltech) have created images of the heart's muscular layer that show, for the first time, the connection between the configuration…
Chemists create stable, highly pure helical peptide arrays
— 18 Aug 2008 11:26 | ChemistryBedsprings aren't often found in biology. Now, chemists have succeeded in making a layer of tiny protein coils attached to a surface, much like miniature bedsprings in a frame. This…
New mechanism discovered for DNA recombination and repair
— 12 Sep 2007 14:08 | ChemistryA biochemistry research team led by Dr Andrew H.-J. Wang and Dr Ting-Fang Wang at the Institute of Biological Chemistry, Academia Sinica (IBCAS), has discovered that the RecA family…
