In the biofilm regulation pathway of Pseudomonas fluorescens and similar bacteria, high phosphate levels lead to the creation of messenger molecule cyclic-di-guanosin monophosphate (CDGMP). cdGMP activates key regulatory protein LapD through its cytoplasmic domains.

Within the past decade it was discovered that many cells have an adaptive immune system to fight off foreign RNA or DNA which may have been inserted by a viral, plasmid or transposon attack.

In July, twenty public school teachers visited the eXploration Station as a part of the Summer Science Snapshot for Educators program.

CHESS has recently procured a Bio-Logic SP-200 potentiostat, an instrument that controls a three-electrode cell in electrochemical experiments, thanks to funding from the Energy Materials Center at Cornell. Key features of the SP-200 model (Figure 1) are found here.

The research work published in the August issue of Nano Letters report the development of the world’s smallest anvil pressure cell, which offers a new experimental platform for investigating the elastic behavior of molecular bundles embedded at nanocrystal interfaces of nanocomposites.

Modern crystallography can be tracked back to Max Laue who conceived the first diffraction of x-ray by a crystal lattice in 1913. Upon public release of the Laue pattern collected from several crystals, Albert Einstein immediately labeled this work as one of the most beautiful experiments in physics.

Physics graduate student Siddharth Karkare is the first author on a recent Physical Review Letters publication reporting new interdisciplinary research on "Ultrabright and Ultrafast III-V Semiconductor Photocathodes" that could dramatically improve accelerator performance (1).

Cornell faculty members Geoffrey Coates and Fred McLafferty have received national American Chemical Society (ACS) awards. Both receiving $5,000 prizes, they will be honored at a March 24 ceremony during the ACS meeting in Denver.
