NMR advance relies on microscopic detector
... Elucidating structure is critically important for biologists because structure determines function, said Zhang. The goal for the project was to create an NMR detector sensitive enough to detect structural information using the amount of protein in a spot on a two-dimensional gel used for electrophoresis (about...Simple equations track Listeria trails

UCLA molecular biologists have turned protein sequences into original compositions of classical music.

New Haven, Conn. A team of biologists at Yale University and the University of Sheffield discovered anatomical details about the female reproductive tract in waterfowl that indicate that male and female anatomy have co-evolved in a "sexual arms race." In most birds, copulation consists...Plants with male and bisexual flowers on the same plant are better mothers
