Researchers identify genetic sequence that helps to coordinate synthesis of DNA-packaging proteins
Seven years ago, Dr. Joe Gall of the Carnegie Institute in Baltimore, Md. and coworkers noticed an aggregation of molecules along a a block of genome that…
'Defective' virus surprisingly plays major role in spread of disease, UCLA life scientists report
Defective viruses have genetic mutations or deletions that eliminate their essential viral functions. They have been observed for many human pathogens and are…
Chemists Devise Inexpensive, Benchtop Method for Marking and Selecting Cells

How bees decide what to be
Johns Hopkins scientists report what is believed to be the first evidence that complex, reversible behavioral patterns in bees – and presumably other animals –…
In Fly DNA, the Footprint of a Fly Virus
In a curious evolutionary twist, several species of a commonly studied fruit fly appear to have incorporated genetic material from a virus into their genomes,…
