'Fat worms' inch scientists toward better biofuel production
Fat worms confirm that researchers from Michigan State University have successfully engineered a plant with oily leaves—a feat that could enhance biofuel production as well as lead to improved animal feeds.
Molecular twist helps regulate the cellular message to make histone proteins
Histone proteins are the proteins that package DNA into chromosomes. Every time the cell replicates its DNA it must make large amounts of newly made histones to organize DNA within the nucleus.
Researchers zap huge global spam 'botnet'
