Even long after it is formed, a memory in rats can be enhanced or erased by increasing or decreasing the activity of a brain enzyme, say researchers supported, in part, by the National Institutes of Health.

Dr. David Levin, Professor of Molecular & Cell Biology at Boston University Henry M. Goldman School of Dental Medicine and Professor of Microbiology at Boston University School of Medicine discovered recently a novel, evolutionarily conserved mechanism for the regulation of gene expression. The study describing this work titled, "Mpk1 MAPK Association with the Paf1 Complex Blocks Sen1-Mediated Premature Transcription Termination," appears in the March 4 issue of Cell.

Biotechnology

A new microscope invented by scientists at Howard Hughes Medical Institute's Janelia Farm Research Campus will let researchers use an exquisitely thin sheet of light -- similar to that used in supermarket bar-code scanners -- to peer inside single living cells, revealing the three-dimensional shapes of cellular landmarks in unprecedented detail. The microscopy technique images at high speed, so researchers can create dazzling movies that make biological processes, such as cell division, come alive.

Biotechnology

Using a bone-creating protein to augment the maxillary sinus could improve dental implant success, according to Georgia Health Sciences University researchers.
