Surgeons at the Oregon Health & Science University Digestive Health Center have developed a new technique that makes feasible and safe a potentially lifesaving and noninvasive surgical procedure known as laparoscopic esophagectomy. Until now, the procedure was considered too technically demanding for most surgeons to perform. A paper on their findings recently was presented at the European Association of Endoscopic Surgery in Venice, Italy.
For more than a decade, the original procedure has been used in a few specialized centers around the world to remove cancer as well as other diseased tissue of the esophagus laparoscopically, that is by inserting fiber-optic instruments into a small, quarter-sized incision in the abdomen and maneuvering them to the affected portion of the esophagus while observing with a camera.
When first introduced, the less invasive laparoscopic esophagectomy was embraced by surgeons eager to forgo traditional open surgery, which requires cutting through the patients chest. But it proved so difficult and time-consuming that most surgeons abandoned it, according to John G. Hunter, M.D., co-director of the OHSU Digestive Health Center, chairman of surgery in the OHSU School of Medicine, and co-author of the paper.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
