If you're watching the complex processes in a living cell, it is easy to miss something important -especially if you are watching changes that take a long time to unfold and require high-spatial-resolution imaging. But new research makes it possible to scrutinize activities that occur over hours or even days inside cells, potentially solving many of the mysteries associated with molecular-scale events occurring in these tiny living things. http://www.physorg.com/news177763702.html Nanotechnology Wed, 18 Nov 2009 11:00:03 EST news177763702 We still have a lot to discover about the mechanism in plants that ensures cell growth in a specific direction. However it is clear that a structure of parallel protein tubes plays an important role. Simon Tindemans investigated this structure during his doctoral research at the FOM Institute for Atomic and Molecular Physics, The Netherlands. According to him small 'catastrophic collisions' are a crucial part of the process leading to its creation. http://www.physorg.com/news171136989.html Biology Wed, 02 Sep 2009 22:40:01 EST news171136989 Two new construction manuals are now available for the world's smallest lamps. Based on these protocols, scientists from the Max Planck Institute of Colloids and Interfaces have tailor-made nanoparticles that can be used as position lights on cell proteins and, possibly in the future as well, as light sources for display screens or for optical information technology. http://www.physorg.com/news165236713.html Nanotechnology Fri, 26 Jun 2009 12:50:01 EST news165236713 Researchers at the University of Texas Medical Branch at Galveston have discovered two biochemical pathways that the Ebola virus relies on to infect cells. Using substances that block the activation of those pathways, they've prevented Ebola infection in cell culture experiments - potentially providing a critical early step in developing the first successful therapy for the deadly virus. http://www.physorg.com/news164997495.html Medicine & Health Tue, 23 Jun 2009 17:39:10 EST news164997495 In a new study this week in Nature, researchers at Brandeis University and the MRC Laboratory of Molecular Biology (Cambridge, U.K.) for the first time shed light on a crucial step in the complex process by which human genetic information is transmitted to action in the human cell and frequently at which point genetic disease develops in humans. http://www.physorg.com/news157374235.html Medicine & Health Fri, 27 Mar 2009 12:05:28 EST news157374235 (PhysOrg.com) -- When viruses and bacteria invade the body, the immune system generates protective proteins called antibodies that bind to and destroy the invading pathogens. http://www.physorg.com/news157222416.html Medicine & Health Wed, 25 Mar 2009 17:54:34 EST news157222416 Canadian researchers have identified a new protein in the progression of breast cancer. According to a recent study from the Université de Montréal and the University of Alberta, published in the Journal of Biological Chemistry, the protein ARF1 plays a critical role in cancer cell growth and the spread of tumours. Targeting this protein with drug therapy may provide hope to women with breast cancer. http://www.physorg.com/news151151667.html Medicine & Health Wed, 14 Jan 2009 10:34:27 EST news151151667 During the past 20 years, researchers have identified thousands of cell protein interactions, with the ultimate goal of inventorying all that occur within cells of various organisms - a comprehensive catalogue known as the interactome. Such information will be critical to understanding the basic mechanics of cellular life, and how malfunctions in these processes contribute to cancer. http://www.physorg.com/news150482969.html Medicine & Health Tue, 06 Jan 2009 16:49:29 EST news150482969 This research by Thomas Leung, Ph.D., and his team in the GSK-IMCB Group at the Institute of Molecular and Cell Biology (IMCB), under Singapore's Agency for Science, Technology and Research, is fundamental to the understanding of how assembles its internal machinery required for cell movement. http://www.physorg.com/news142519574.html Biology Mon, 06 Oct 2008 13:46:14 EST news142519574
