News from the Cell Biology Meeting in San Francisco
Cancer works its malignant will by standing cell life on its head. No form of cancer is better at flipping normal cell mechanisms for growth and movement into sinister contraptions for evasion and invasion than aggressive colorectal tumors. Kidnapping is a particular talent, especially along the cancers invasive edges. Thats where Avri Ben-Zeev and colleagues at the Weizmann Institute of Science in Israel and elsewhere found an unlikely hostage to colorectal cancer in L1, a protein more commonly produced by growing nerve cells. Their findings were presented Tuesday at the 45th Annual Meeting of the American Society for Cell Biology in San Francisco.
Ben-Zeev and Nancy Gavert, a surgeon and current Ph.D. student--were led to the kidnapped nerve cell protein, L1, by their long-term interest in beta-catenin, a cadherin-binding protein, known to also activate genes in various types of cancer. In previous studies, the Ben-Zeev lab identified several beta-catenin target genes that are involved in development of malignant melanoma and colon cancer. The co-option of L1, though, was a surprise.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
