(PhysOrg.com) -- Our breakfast egg is a peculiarity of nature: a single cell protected by a thin mineral layer. Apart from a number of tiny radiolaria and diatoms, individual cells normally do not have a hard shell. Korean researchers have now developed a strategy for equipping individual cells of baker`s yeast, Saccharomyces cerevisiae, with a synthetic shell made of silicon dioxide. As the team led by Insung S. Choi reports in the journal Angewandte Chemie, the lifespan of these coated yeast cells is tripled, whilst their division is suppressed. The shell also protects the cells from unfavorable external conditions. http://www.physorg.com/news176474495.html Chemistry Tue, 03 Nov 2009 12:47:08 EST news176474495 (PhysOrg.com) -- How small is too small to be useful? Researchers at North Carolina State University have done nanoscale analysis on ferroelectric thin films - materials that are used in electronic devices from computer memories to iPhones and polarize when exposed to an electric charge - and found that when it comes to polarization, both size and location matter. http://www.physorg.com/news140106123.html Nanotechnology Mon, 08 Sep 2008 15:22:03 EST news140106123 Human cells somehow squeeze two meters of double-stranded DNA into the space of a typical chromosome, a package 10,000 times smaller than the volume of genetic material it contains. http://www.physorg.com/news138540908.html Medicine & Health Thu, 21 Aug 2008 12:35:08 EST news138540908
