Scientists in Japan are reporting an advance toward giving artificial cells another hallmark of life -- the ability to tap an energy source and use it to undergo sustained movement. Their study, published in the Journal of the American Chemical Society, describes the first `self-propelled` oil droplets (used as a model for research on artificial cells) that can run on a chemical `fuel.` http://www.physorg.com/news160233585.html Chemistry Wed, 29 Apr 2009 14:20:03 EST news160233585 A simple, chemical materials model may lead to a better understanding of the structure and organization of the cell according to a Penn State researcher. http://www.physorg.com/news153830013.html Chemistry Sat, 14 Feb 2009 10:35:16 EST news153830013 Researchers at Yale University have created a blueprint for artificial cells that are more powerful and efficient than the natural cells they mimic and could one day be used to power tiny medical implants. http://www.physorg.com/news142763924.html Nanotechnology Thu, 09 Oct 2008 09:38:44 EST news142763924
