Van Andel Research Institute (VARI) researchers have determined precisely how the plant hormone abscisic acid (ABA) works at the molecular level to help plants respond to environmental stresses such as drought and cold. Their findings, published in the journal Nature, could help engineer crops that thrive in harsh environments around the world and combat global food shortages. The findings could also have implications for stress disorders in humans. http://www.physorg.com/news179060030.html Biology Thu, 03 Dec 2009 10:54:35 EST news179060030 (PhysOrg.com) -- In structural biology, the only technique available to predict the three dimensional structure of large complex molecules in solution, such as proteins and DNA, is NMR spectroscopy. To catalyze improvements in the techniques behind these predictions, the "eNMR" project has launched a new initiative. In September`s Nature Methods the project issued an invitation to the entire biomolecular Nuclear Magnetic Resonance community to participate in a large scale test of modern computing algorithms. This community-wide `contest` will potentially improve efficiency, reproducibility and reliability of NMR structure determination. eNMR will be using the Enabling Grids for E-sciencE infrastructure to power their analysis. http://www.physorg.com/news178785696.html Chemistry Mon, 30 Nov 2009 07:10:01 EST news178785696 Structural biologists at the University of Pittsburgh School of Medicine have described the architecture of the complex of protein units that make up the coat surrounding the HIV genome and identified in it a "seam" of functional importance that previously went unrecognized. Those findings, reported today in Cell, could point the way to new treatments for blocking HIV infection. http://www.physorg.com/news177251386.html Medicine & Health Thu, 12 Nov 2009 12:40:02 EST news177251386 Scientists at the University of York have discovered how certain bacteria such as Escherichia coli have evolved to capture rare sugars from their environment giving them an evolutionary advantage in naturally competitive environments like the human gut. http://www.physorg.com/news177244138.html Chemistry Thu, 12 Nov 2009 10:31:40 EST news177244138 (PhysOrg.com) -- Biologists led by associate professor Thomas Schwartz (MIT) have worked out a rudimentary architectural plan for the nuclear pore complex (NPC), the gatekeeper of the cell's nucleus. http://www.physorg.com/news175881788.html Biology Tue, 27 Oct 2009 17:04:11 EST news175881788 Scientists at the University of York have uncovered the structure of an unusual enzyme which can be used to reverse the contamination of land by explosives. http://www.physorg.com/news174302821.html Chemistry Fri, 09 Oct 2009 10:27:31 EST news174302821 New research announced today, Wednesday 30th September, by a team of leading scientists working with the UK's national Synchrotron, Diamond Light Source, could have a significant impact on the development and refinement of new eco-friendly pest control methods for worldwide agriculture. http://www.physorg.com/news173452384.html Biology Tue, 29 Sep 2009 14:40:01 EST news173452384 Researchers from CIC bioGUNE's Structural Biology Unit and Columbia University (New York) have conducted a joint research project, published in the prestigious scientific journal Structure, to gain in-depth knowledge of the structure of pyruvate carboxylase when it is in solution (in the "natural" state). http://www.physorg.com/news168689251.html Biology Wed, 05 Aug 2009 11:08:01 EST news168689251 Scientists at Albert Einstein College of Medicine of Yeshiva University have discovered how a gene crucial in triggering the spread of breast cancer is turned on and off. The findings could help predict whether breast tumors will metastasize and also reveal potential drug targets for preventing metastasis. The study will appear in the May 20th online edition of the Journal of Cell Science. http://www.physorg.com/news161355941.html Medicine & Health Tue, 12 May 2009 14:06:16 EST news161355941 (PhysOrg.com) -- Sea urchins dig themselves hiding holes in the limestone of the ocean floor using teeth that don`t go blunt. Weizmann Institute scientists have now revealed their secrets, which might give engineers insights into creating ever-sharp tools or mechanical parts. http://www.physorg.com/news160670680.html Biology Mon, 04 May 2009 15:45:19 EST news160670680 In a paper published in the early online version of Nature Structural and Molecular Biology, researchers at the University of Pittsburgh School of Medicine deconstruct the first steps in an intricate molecular dance that might lead to the formation of pathogenic protein clumps in Huntington's disease, and possibly other movement-related neurological disorders. http://www.physorg.com/news155749490.html Biology Sun, 08 Mar 2009 16:45:59 EST news155749490 In a breakthrough study appearing in advance online publication of Nature Methods, researchers at Albert Einstein College of Medicine of Yeshiva University describe for the first time a method of viewing individual breast cancer cells for several days at a time. The study, by scientists in Einstein's Gruss Lipper Biophotonics Center, provides detail on how cancer cells invade surrounding tissue and reach blood vessels. These movements are the first steps of the potentially deadly stage of cancer known as metastasis. http://www.physorg.com/news145715277.html Medicine & Health Wed, 12 Nov 2008 12:27:57 EST news145715277 A spin out company from basic structural biology, Asterion Ltd., has led to new technology that provides a way of creating therapeutic proteins to tackle major diseases such as cancer, diabetes and infertility. The research was carried out at the University of Sheffield in laboratories supported by the Biotechnology and Biological Sciences Research Council (BBSRC). This work is reported in the current edition of BBSRC Business, the quarterly research highlights magazine of the Biotechnology and Biological Sciences Research Council. http://www.physorg.com/news137324670.html Biology Thu, 07 Aug 2008 10:44:30 EST news137324670 In an Australian first, scientists at Sydney's Centenary Institute have mapped the anatomy of a membrane protein.
