Stony Brook researchers and colleagues use high-resolution imaging of proteins to develop the theory A team of scientists led by Stony Brook University biochemist Huilin Li, PhD, have proposed that DNA is unwound by a type of “pumpjack” mechanism, similar to the way one operates on an oil rig. Their finding, published in Nature Structural & Molecular Biology, is based on new close-up images of the proteins that unwind DNA inside the nucleus of a yeast cell and could offer insight into ways that DNA replication can go awry and trigger disease. “DNA replication is a major source of errors…

Stony Brook University Physics Dmitri Kharzeev, in collaboration with a team of scientists at the U.S Department of Energy’s (DOE) Brookhaven National Laboratory, has discovered a new way to generate very low-resistance electric current in a new class of materials. The discovery, which relies on the separation of right- and left-“handed” particles, points to a range of potential applications in energy, quantum computing, and medical imaging, and possibly even a new mechanism for inducing superconductivity–the ability of some materials to carry current with no energy loss. The material the scientists worked with, zirconium pentatelluride, has a surprising trait: When placed…

Using  bundled strands of DNA to build Tinkertoy-like tetrahedral cages, scientists have devised a way to trap and arrange nanoparticles in a way that mimics the crystalline structure of diamond. The achievement of this complex yet elegant arrangement, as described in a paper published in Science, may open a path to new materials that take advantage of the optical and mechanical properties of this crystalline structure for applications such as optical transistors, color-changing materials, and lightweight yet tough materials. Huilin Li, PhD, a Professor in the Department of Biochemistry and Cell Biology at Stony Brook University, is part of the…

Samuel McDermott, a postdoc at Stony Brook’s C.N. Yang Institute for Theoretical Physics, is co-author of a groundbreaking paper on dark matter to be published January 18 by physicists at the U.S. Department of Energy’s Brookhaven National Laboratory, Fermi National Accelerator Laboratory, and Stony Brook University. The paper, authored by Hooman Davoudias and published in Physical Review Letters, suggests a shorter secondary inflationary period that could account for the amount of dark matter estimated to exist throughout the cosmos. Standard cosmology—that is, the Big Bang Theory with its early period of exponential growth known as inflation—is the prevailing scientific model for our universe, in which…

Barbara Chapman, a leading researcher in programming languages, programming models and compilers, has been named head of the Computer Science and Mathematics Group (CSM) under the new Computational Science Initiative (CSI) at Brookhaven National Laboratory (BNL). Chapman is a professor of Applied Mathematics and Statistics and Computer Science at Stony Brook University, where she serves as a joint appointee affiliated with the University’s Institute for Advanced Computational Science (IACS). The CSI leverages computational science, computer science, and mathematics expertise and investments across multiple research areas at the Laboratory — including the flagship facilities that attract thousands of scientific users each year…

The Long Island Bioscience Hub (LIBH), in cooperation with the Center for Biotechnology at Stony Brook University, awarded 13 technology development grants totaling $900,000 to researchers from Stony Brook University, Cold Spring Harbor Laboratory and Brookhaven National Laboratory. These grants represent a multi-tiered funding initiative aimed at contributing to a pipeline of commercially promising biomedical technology in the region. The three funding initiatives include Feasibility, Proof of Concept and Commercialization awards. Feasibility awards are designed to rapidly test the feasibility of new ideas in a “fail-fast-or-proceed” format, or to add value to existing intellectual property leading to new market applications…

Prachi Chitnis, a Stony Brook University graduate student mentored by Kevin Brown, a physicist at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory’s Collider-Accelerator Department, has been awarded the 2015 Experimental Physics Control Systems Prize by the European Physical Society (EPS) for her “significant contributions to the reliability of the RHIC beam permit system.” Chitnis traveled to Australia in October to accept the award. Chitnis, a PhD candidate in electrical engineering, has focused her thesis work on machine protection systems; in particular, analyzing reliability and vulnerabilities of the beam permit and quench detector systems at Brookhaven’s Relativistic Heavy Ion…

In a partnership with Stony Brook researchers, scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have released the first-ever images of the protein complex that unwinds, splits, and copies double-stranded DNA. The electron microscope images offer new insight into how this molecular machinery functions, including new possibilities about its role in DNA “quality control” and cell differentiation. The images and implications are described in a paper published online by the journal Nature Structural & Molecular Biology, November 2, 2015. Rockefeller University scientists also worked in partnership with the project. “This work is a continuation of our long-standing research…

Senior research officers from member universities of The Science Coalition and Association of American Universities met on July 15 for All Things Research, a roundtable discussion held at the National Press Club in Washington, DC. Among them was Stony Brook University’s Vice President for Research David O. Conover, who also serves as operations manager for the SUNY Research Foundation. Members of these two groups share a common goal of maintaining America’s leadership in science and technology through strong and sustained funding for scientific research across all disciplines. Each year at All Things Research, senior research officers discuss with DC-based journalists…

It took only six months for Stony Brook University to hit an energy research grand slam, earning major federal funding on four projects poised to revolutionize the world’s energy technology. “These four projects, which together earned nearly $5.7 million in funding, showcase Stony Brook’s dedication to researching and developing technologies that will have a major impact on how we generate and consume energy globally,” said Samuel L. Stanley Jr., MD, President of Stony Brook University. But how can a state university on Long Island suddenly secure such funding and rise to rank alongside renowned energy research institutions like MIT and…
