Materials scientist Jeffrey Brinker and his collaborators at Sandia National Laboratory in Albuquerque, N.M., have confined individual Staphylococcus aureus cells in vessels that consist of porous silica nanostructures. These structures isolate the cells physically and chemically from other cell... Read More
Dotplots are an extremely useful way of visualizing comparisons of small and large DNA sequences (as well as protein sequences), providing insight into the degree of similarity, deletions, insertions and direct and indirect repeats. In a dotplot, each nucleotide, or small window of nucleotides, ... Read More
