Most cellular processes are carried out by molecular machines that consist of many interacting proteins. These protein complexes lie at the heart of life science research, but they are notoriously hard to study. Their abundance is often too low to extract them directly from cells and generating them with recombinant methods has been a daunting task. http://www.physorg.com/news160662977.html Chemistry Mon, 04 May 2009 13:36:51 EST news160662977 In their ongoing study of the processes involved in embryonic development in fruit flies, researchers at WPI's Life Sciences and Bioengineering Center at Gateway Park have identified the function of a protein that sticks out of the embryonic cell membrane like an antenna and processes signals needed for the flies' wings to develop properly. http://www.physorg.com/news154181694.html Biology Wed, 18 Feb 2009 12:15:25 EST news154181694 (PhysOrg.com) -- Plants, algae, and cyanobacteria (blue-green algae) are masters of everything to do with solar energy because they are able to almost completely transform captured sunlight into chemical energy. This is in part because the electrons set free by the photons are transported out of the `light receptor` 1:1 to be used as the driving force for chemical reactions. http://www.physorg.com/news153556173.html Chemistry Wed, 11 Feb 2009 06:33:12 EST news153556173 (PhysOrg.com) -- Blocking a specific protein complex prevents the formation of tumors in mice genetically predisposed to develop prostate cancer, researchers at the Whitehead Institute for Biomedical Research have found. Interestingly, inhibiting this protein complex in non-cancer cells appears to have no impact, suggesting that the protein complex may represent a promising target for drug development. http://www.physorg.com/news152896902.html Medicine & Health Tue, 03 Feb 2009 15:22:09 EST news152896902 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
