Neutrons Run Enzyme's Reactivity

Authors: George Rajna

Researchers from the Department of Energy's Oak Ridge National Laboratory and North Carolina State University used a combination of X-ray and neutron crystallography to determine the detailed atomic structure of a specialized fungal enzyme. [19] Complex biological processes such as metabolism often involve thousands of compounds coupled by chemical reactions. These process chains are described by researchers as chemical reaction networks. [18] High performance motion detection technology is critical as the 'eyes' of advanced robotic systems for applications including factory management and autonomous machines in home environments. [17] A diagnostic technique that can detect tiny molecules signaling the presence of cancer could be on the horizon. [16] For the past 15 years, the big data techniques pioneered by NASA's Jet Propulsion Laboratory in Pasadena, California, have been revolutionizing biomedical research. On Sept. 6, 2016, JPL and the National Cancer Institute (NCI), part of the National Institutes of Health, renewed a research partnership through 2021, extending the development of data science that originated in space exploration and is now supporting new cancer discoveries. [15] IBM scientists have developed a new lab-on-a-chip technology that can, for the first time, separate biological particles at the nanoscale and could enable physicians to detect diseases such as cancer before symptoms appear. [14] Scientists work toward storing digital information in DNA. [13] Leiden theoretical physicists have proven that DNA mechanics, in addition to genetic information in DNA, determines who we are. Helmut Schiessel and his group simulated many DNA sequences and found a correlation between mechanical cues and the way DNA is folded. They have published their results in PLoS One. [12]
