Consortium Awarded $22.5M for X-ray Laser Research

Sep 26, 2018

30 min 41 sec ago A research consortium led by UB has been awarded $22.5 million from the National Science Foundation (NSF) to continue its groundbreaking work developing advanced imaging techniques for critical biological processes that are difficult, if not impossible, to see with conventional methods. BioXFEL, an NSF Science and Technology Center and UB’s first such center, was created in November 2013 with an initial, $25 million award to UB, Hauptman-Woodward Medical Research Institute (HWI) and partner institutions. “The successful renewal of UB’s first NSF Science and Technology Center award confirms Western New York’s leadership in the areas of X-ray crystallography and structural biology, historically based in the Hauptman-Woodward Medical Research Institute and related departments at UB, including, most recently, the Department of Materials Design and Innovation,” says Venu Govindaraju, UB vice president for research and economic development. “BioXFEL center scientists have made revolutionary advances in just a few years, using X-ray lasers to probe phenomena previously hidden from view,” he says. “They have discovered about 350 new molecular structures, expanding the knowledge base by describing these structures in more than 500 publications. With these incredibly powerful new tools, they are helping us better understand some of society’s most intractable health and science problems.” In addition to UB and HWI, BioXFEL partners include Arizona State University, the University of Wisconsin-Milwaukee, Stanford University, Cornell University, Rice University, the University of California, San Francisco, and Miami University in Ohio. The goal of the research is to harness the power of X-ray lasers to transform a broad range of scientific fields focused on structural biology and drug development, and extending to potential innovations in environmental technologies and development of new materials. UB scientist Thomas Grant has used X-ray free laser techniques to develop a new way to look at molecular structures in solution. Thanks to this new method, this image of a biomolecule reveals its intricate internal structure in orange, red and yellow. Until now, scientists would only have been able to see the blue outline. Image: First published in Nature Methods on Jan. 29, 2018 Called BioXFEL, short for Biology with X-ray Free Electron Lasers, the consortium of UB, HWI and partners is dedicated to using X-ray free electron lasers, which produce incredibly intense X-rays in extremely short pulses. “X-ray lasers provide two huge advantages over conventional methods,” explains Edward Snell, BioXFEL director, president and CEO of HWI, and professor in the Department of Materials Design and Innovation at UB. “They are intensely bright beams that allow us to see much smaller things, like nanocrystals. And their pulses are incredibly short, which allows us to see critical processes, like how drugs bind, at rates as fast as a billionth of a billionth of a second.” BioXFEL is developing the next-generation of X-ray-based structural biology research, a field in which Buffalo has a long and rich history. In 1985, the Nobel Prize was awarded to the late Herbert Hauptman and Jerome Karle for their work developing the groundbreaking direct methods technique, a robust means of obtaining the shape and form of pharmaceuticals and their targets that is still used today, Snell says. In the few years that BioXFEL has existed, Snell notes its researchers have significantly expanded the detail with which biological and other processes can be imaged. “Initially, the molecular images we made were based on distinct snapshots of molecules at certain timepoints,” he says. “Now we’re going from the photograph to the movie; we’re able to see the continuous process. With this renewal, we will be able to understand the complete dynamics of biological mechanisms.” HWI’s role in BioXFEL stems from its high-throughput crystallization center that over the past two decades has generated 180 million images from crystallization experiments. Many of these crystals were too small to be analyzed by conventional techniques, but may be deciphered using the power of X-ray lasers. The same images have attracted a collaboration with Google Brain, in this case promoting the use of artificial intelligence to expedite new discoveries in protein crystallization. “Buried within all those images are clues about how to go about finding the useful data in them more easily, but there is a lot of noise and we’ve got to work out a way to tease out the clues by somehow automating the process,” Snell says. “It’s well-known that we have this archive of images at HWI generated by our High-Throughput Crystallization Center, so crystallization centers and major pharmaceutical companies worldwide have been eager to collaborate with us.” UB scientist Thomas Grant, who is based at HWI, has used X-ray free laser techniques to develop a new way to look at molecular structures in solution, critical for understanding how proteins function in the human body. Other BioXFEL advances include: Developing a method that dramatically reduces the amount of sample needed for analysis. Viewing the motions of molecules during reactions called time-resolved imaging dynamics, which allowed researchers to see how antibiotic resistance develops in tuberculosis and how a virus infects its host. Using X-ray lasers to probe molecular motion studies for new technologies and materials. Eight supported faculty at Arizona State University, where a compact campus XFEL is under construction, who use worldwide XFEL facilities to obtain movies of molecular machines at work in photosynthesis, viruses and drugs, while developing experimental techniques and new algorithms. Four supported faculty at the University of Wisconsin-Milwaukee, leading to the first movies of biological processes underlying vision, antibiotic resistance and the extrusion of the genome from a virus. New technology developed at Cornell University that has enabled the first millisecond scale mix and inject experiments: watching proteins as they work with near atomic resolution. The scientific work of BioXFEL takes place through collaborations between all of the partner institutions. The initial X-ray laser experiments can only be done at the Linac Coherent Light Source at BioXFEL partner Stanford University, where a mile-long facility produces a beam one-tenth of the thickness of a human hair.
