If you want to understand a novel, it helps to start from the beginning rather than trying to pick up the plot from somewhere in the middle. The same goes for analyzing a strand of DNA. The best way to make sense of it is to look at it head to tail.
How do viruses attach to cells? How do proteins interact and mediate infection? How do molecular machines organize themselves in healthy cells? How do they differ in diseased cells? These are the types of questions National Institutes of Health researchers ask in the recently established Living Lab for Structural Biology, questions they strive to answer through the most sophisticated of imaging techniques.
Animal cells behave like fluid-filled sponges in response to being mechanically deformed according to new research published today in Nature Materials.
High-speed atomic force microscopy (HS-AFM) is providing the means to produce dramatic footage of moving biomolecules, and scientists at Kanazawa University leading the field. This research is also described in the inaugural December issue of the Kanazawa University Research Bulletin: http://www.kanazawa-u.ac.jp/research_bulletin/index
An EPFL team has developed a technique for spying on the inner lives of cells. For the first time, scientists have used a near-infrared, light-sensitive biocompatible molecule to mark and observe the activity of proteins inside living cells.
Two professors from The University of Texas at Austin will be honored by President Barack Obama with the National Medal of Science. Allen Bard, in the College of Natural Sciences, and John Goodenough, in the Cockrell School of Engineering, are two of 12 eminent researchers who will receive the medal this year, bringing the university’s overall total to five since 1962.
EPFL scientists used microfluidics to observe the behavior of individual tuberculosis-like bacteria in the presence of antibiotics. Their observations call into question the prevailing theory of bacterial resistance, and they have proposed a new explanation for why some bacteria become resistant. The research is published January 4, 2013 in the journal Science.
The winner of the 2012 Feynman Prize for Experiment is the team of Gerhard Meyer, Leo Gross, and Jascha Repp for their work at IBM Research in Zurich (Dr. Repp is now at Regensburg University).
Scientists trying to decipher the microenvironment of living biological tissues now have a way of taking high-resolution, high-speed, three-dimensional images of their inner workings.
For applications, such as material testing for quality control purposes or highly dynamic control of valves in test stands, PI (Physik Instrumente) presents the E-482, a new high-power piezo amplifier / controller with 6 A peak current at 1050 V voltage swing.
