Biologists have long wondered how it's possible for each nerve cell to be equipped with only one kind of olfactory receptor (OR). There are over a thousand different kinds of OR genes in humans, distributed widely over both chromosomes; mice, dogs, and other animals have many more. https://phys.org/news/2013-03-epigenetics.html Cell & Microbiology Tue, 05 Mar 2013 07:03:14 EST news281689238 (Phys.org)—Cornell researchers have discovered that a protein known for moving cells around in the body also helps regulate a cellular organelle responsible for generating one-third of all proteins in the human body. https://phys.org/news/2012-12-protein-cells-stress.html Cell & Microbiology Fri, 21 Dec 2012 07:40:01 EST news275296189 When cells undergo potentially catastrophic damage, for example as a result of exposure to ionizing radiation, they must make a decision: either to fix the damage or program themselves for death, a process called apoptosis. https://phys.org/news/2009-04-scientists-key-decision-point-cells-broken.html Biochemistry Fri, 10 Apr 2009 12:20:00 EDT news158584593
