In this ongoing quest, a group of Scripps Research Institute scientists, along with colleagues from the University of California, San Diego, (UCSD) have borrowed from physics to deliver one of those research rarities—an unmitigated success. The group has devised a computational method that, with remarkable accuracy, predicts how bacterial proteins fold and interact.

A Princeton-led team of researchers has discovered an entirely new mechanism for making common electronic materials emit laser beams. The finding could lead to lasers that operate more efficiently and at higher temperatures than existing devices, and find applications in environmental monitoring and medical diagnostics.

Chemists in Canada have developed a new approach for producing more effective medical antifreeze fluids for preserving kidneys, hearts, and other organs donated for transplantation. These next-generation antifreezes can decrease damage to organs caused by ice crystals, and thus prolong the time a donated organ will remain viable prior to transplantation.

The researchers adopted polishing technology used in the semiconductor industry (chemical mechanical planarization) to polish the surface of human teeth down to nanoscale roughness. Roughness left on the tooth after the polishing is just a few nanometers, which is one-billionth of a meter or about 100,000 times smaller than a grain of sand.

The former picked those sites for battlefields a century and a half ago; the latter like them today for big-box stores.
