From shells to bones, the skeletons of organisms contain small amounts of impurity elements such as magnesium. Because the levels of these elements provide important clues to past environments, a considerable effort has focused on understanding how to relate impurity contents to the ancient environments in which an organism lived.

An important discovery has been made with respect to the mystery of “handedness” in biomolecules. Researchers led by Sandra Pizzarello, a research professor at Arizona State University, found that some of the possible abiotic precursors to the origin of life on Earth have been shown to carry “handedness” in a larger number than previously thought.

Scientists Develop Novel Fluorescent Proteins for Live Cell Imaging, Biosensor Design

Scientists at Carnegie Mellon University's Molecular Biosensor and Imaging Center (MBIC) have developed new "fluorogen activating proteins" (FAPs) that will become a key component of novel molecular biosensor technology being created at Carnegie Mellon. The FAPs, which can be used to monitor biological activities of individual proteins and other biomolecules within living cells in real time, are described in the February issue of Nature Biotechnology.

Click chemistry, one of the most exciting and proficient new techniques for labeling biomolecules in vitro, has now been extended to studies in the context of live cells as well. This breakthrough opens the door for applications to live cell imaging of numerous biomolecules, including glycans, proteins and lipids. The new version of click chemistry was developed by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) at Berkeley.
