Forces exerted by a living cell or a microorganism are tiny, often no larger than a few nanonewtons. For comparison, one nanonewton is the weight of one part in a billion of a typical chocolate bar. Yet, for biological cells and microbes, these forces are enough to allow cells to stick to a surface or microbes to propel themselves toward nutrients. Scientists from Finland and Germany now present a highly adaptable technique using micropipette force sensors to precisely measure the forces exerted by a wide range of micron-sized organisms. This novel method has now been published in Nature Protocols. https://phys.org/news/2019-01-cells-microorganisms.html Biochemistry Mon, 28 Jan 2019 11:00:12 EST news467888954 European scientists investigated the dynamic unfolding of DNA during replication by generating a tool that could subsequently be applied to screen helicase-targeting drugs for infection and oncologic applications. https://phys.org/news/2012-10-molecular-motors-nucleic-acid-screening.html Cell & Microbiology Thu, 04 Oct 2012 08:20:02 EDT news268556503
