2/10/2016 Mechanism that Unwinds DNA may Function Similar to an Oil Rig "Pumpjack"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.
2/4/2016 Study Reveals Proteins Most Associated With Aging Certain proteins known to be associated with aging and age-related diseases such as Alzheimer's disease and cancer are also at a high risk for destabilization caused by oxidation. This finding by a team of researchers at the Laufer Center for Physical and Quantitative Biology at Stony Brook University provides an understanding of how oxidative damage, which is a natural process in aging cells, affects proteins. It could also prove to be a foundation to a better understanding of age-related diseases. The paper, titled "Highly charged proteins: the Achilles' heel of ageing proteoms," is published in the journal Structure.
2/1/2016 Novel Microscopy Helps Stony Brook Researchers Examine the Ocean Like Never BeforeThere are about one million bacteria, thousands of species and untold genetic diversity in just one drop of seawater. This amazing fact and the powerful roles played by marine microbes in shaping the health of the ocean's ecosystem and our climate has led Gordon T. Taylor, a Professor of Oceanography at Stony Brook University's School of Marine and Atmospheric Sciences (SoMAS), to focus his research on uncovering the wonders of marine microbial life. Now, a new $800,000 grant from the Gordon and Betty Moore Foundation will enable Professor Taylor and colleagues to develop new microscopy-based technologies to probe this environment at levels not seen before.
1/20/2016 Alzheimer's Diagnosis Complicated by History of Reading ProblemsCorrectly diagnosing Alzheimer's disease remains a challenge for medical professionals. Now, a new study published in the current issue of the Journal of Alzheimer's Disease reveals a new clue to possible misdiagnosis. The study found that older adults with a history of reading problems perform similarly on some neuropsychological tests to those who show signs of mild cognitive impairment (MCI) associated with early Alzheimer's disease. The finding, based on the results of a Stony Brook University-led research team in collaboration with Boston University School of Medicine, emphasize the need for professionals to take into account developmental history and have a broad understanding of neuropsychological testing when interpreting the meaning of low memory test scores.
1/19/2016 Stony Brook Researchers Discover Ice-like Phonons in Liquid WaterFor more than 100 years, scientists have debated what the underlying molecular structure of water is, and the common view has been that H2O molecules are either "water-like" or "ice-like." Now through computer simulation conducted at the Institute for Advanced Computational Science (IACS) at Stony Brook University, researchers can illustrate that the structure and dynamics of hydrogen bonding in liquid water is more similar to ice than previously thought. The finding, published in Nature Communications, changes the common understanding of the molecular nature of water and has relevance to many fields, such as climate science and molecular biophysics, and technologies such as desalinization and water-based energy production.
12/31/2015 Heart Attack Patients with History of Bypass Surgery Prone to Delayed TreatmentHeart attack patients who had previously undergone cardiac bypass surgery are about twice as likely to have a delay in receiving angioplasty, or another form of revascularization, compared to heart attack patients who had no history of bypass surgery or previous angioplasty. This finding, from a study led by a Stony Brook Heart Institute cardiologist Luis Gruberg, MD, and published in the journal of the American College of Cardiology Interventions, may lead to a finding new ways to improve hospital arrival to treatment times for heart attack patients with a bypass history.
12/16/2015 Study Reveals Environment, Behavior Contribute to Some 80 Percent of Cancers A team of researchers from Stony Brook University, led by Yusuf Hannun, MD, the Joel Strum Kenny Professor in Cancer Research and Director of the Stony Brook University Cancer Center, have found quantitative evidence proving that extrinsic risk factors, such as environmental exposures and behaviors weigh heavily on the development of a vast majority (approximately 70 to 90 percent) of cancers. The finding, reported in the December 16 online issue of Nature, in a paper titled "Substantial contribution of extrinsic risk factors to cancer development," may be important for strategizing cancer prevention, research and public health.
12/10/2015 Stress-Induced Loss of NG2 Glial Cells in the Brain Causes Depression A Stony Brook University-led research team has discovered that when a rare type of glial cells, called NG2 glia, are depleted from the brain in mice, depressive-like behaviors occur. This finding, published early online in the journal Neuron, helps to advance the understanding of brain changes associated with depression and suggests novel therapeutic targets for antidepressant drug development.
