The research group of Dr. François Robert, a researcher at the Institut de recherches cliniques de Montréal (IRCM), in collaboration with the team of Dr. Daniel Durocher (Samuel Lunenfeld Research Institute and University of Toronto) accomplished a technical breakthrough: they mapped all the fragile sites of a living organism, the budding yeast Saccharomyces cerevisiae. The method used by the researchers can be applied to humans. This study has been published online today in the scientific journal Nature Structural and Molecular Biology. http://www.physorg.com/news184950459.html Biology Tue, 09 Feb 2010 15:08:32 EST news184950459 (PhysOrg.com) -- Shakespeare famously wrote, "That which we call a rose by any other name would smell as sweet." With all due respect to the Bard, University of Florida researchers may have to disagree: no matter what you call a flower, its scent can be changed. http://www.physorg.com/news184947677.html Biology Tue, 09 Feb 2010 15:00:01 EST news184947677 (PhysOrg.com) -- Following the straight and narrow may be good moral advice, but it`s not a great design principle for a distribution network. In new research, a team of biophysicists describe a complex netting of interconnected looping veins that evolution devised to distribute water in leaves. The work, which bucks decades of thinking, may compel engineers to revisit some common assumptions that have informed the building of many human-built distribution networks. http://www.physorg.com/news184947408.html Physics Tue, 09 Feb 2010 14:18:01 EST news184947408 (PhysOrg.com) -- "If only I had..." Almost everyone has said those four words at some time. Rather than intensifying regret, '"what if" reflection about pivotal moments in the past helps people to weave a coherent life story, and fosters their organizational commitment, scholars say. http://www.physorg.com/news184947134.html Other Sciences Tue, 09 Feb 2010 14:13:03 EST news184947134 (PhysOrg.com) -- A team of researchers from Switzerland, California, and Spain have found that particulates from auto exhaust can lead to the thickening of artery walls.

Such would be the ultimate theoretical outcome, Fermi surmised, of the quest for the ever-more powerful accelerators needed to discover new laws of physics. http://www.physorg.com/news184935747.html Physics Tue, 09 Feb 2010 11:20:01 EST news184935747 Subtle head motions are amplified by inner-ear hair cells before the signal is reported to the brain, report Marine Biological Laboratory scientists and colleagues. In both the auditory and the vestibular systems, hair cell response is nonlinear: the lower the strength of the stimulus, the more the hair cell amplifies the signal. http://www.physorg.com/news184935465.html Medicine & Health Tue, 09 Feb 2010 10:57:59 EST news184935465 Researchers in Chicago and London have developed a method for controlling the properties of magnets that could be used to improve the storage capacity of next-generation computer hard drives. http://www.physorg.com/news184935265.html Physics Tue, 09 Feb 2010 10:54:47 EST news184935265 (PhysOrg.com) -- Hydrogen-powered fuel cells and solar energy are the best hope for a more environmentally friendly and resource-sparing energy supply in the future. A combination of the two is considered to be particularly `clean`: the production of hydrogen by splitting water with sunlight. Previous approaches to this have suffered from high costs and the limited lifetime of their catalytic systems. http://www.physorg.com/news184926811.html Chemistry Tue, 09 Feb 2010 09:00:01 EST news184926811 A radical new approach to the design of communications networks, called "network coding," promises to make Internet file sharing faster, streaming video more reliable, and cell-phone reception better -- among other improvements. http://www.physorg.com/news184924443.html Technology Tue, 09 Feb 2010 08:40:05 EST news184924443 (PhysOrg.com) -- Using cryo-electron microscopy and advanced image-processing methods, UCLA researchers have developed a model of how the potentially therapeutic vesicular stomatitis virus assembles. http://www.physorg.com/news184924133.html Biology Tue, 09 Feb 2010 08:40:02 EST news184924133 In the words of Todd Squires, of the University of California, Santa Barbara "Nature has long inspired researchers in fluid mechanics to explore the mechanical strategies used by living creatures. Where better to look for innovative solutions to a technological challenge than to organisms that have had millions of years to devise strategies for related challenges?" http://www.physorg.com/news184925149.html Physics Tue, 09 Feb 2010 08:40:01 EST news184925149 (PhysOrg.com) -- Scientists from the University College London in the U.K. have found that living a life of boredom can kill you. http://www.physorg.com/news184916879.html Medicine & Health Tue, 09 Feb 2010 08:20:05 EST news184916879 High blood fat levels normally raise the cholesterol values in the blood, which in turn elevates the risk of atherosclerosis and heart attack. Now a new study from Lund University in Sweden shows that butter leads to considerably less elevation of blood fats after a meal compared with olive oil and a new type of canola and flaxseed oil. The difference was clear above all in men, whereas in women it was more marginal. http://www.physorg.com/news184924967.html Medicine & Health Tue, 09 Feb 2010 08:20:02 EST news184924967 (PhysOrg.com) -- Certain bacteria cause chronic lung infections in people with cystic fibrosis. Surviving in this oxygen-poor, nitrate-rich environment makes the bacteria less susceptible to antibiotics. http://www.physorg.com/news184923826.html Medicine & Health Tue, 09 Feb 2010 07:44:26 EST news184923826 (PhysOrg.com) -- Eventually, the day will come when life on Earth ends. Whether that`s tomorrow or five billion years from now, whether by nuclear war, climate change, or the Sun burning up its fuel, the last living cell on Earth will one day wither and die. But that doesn`t mean that all is lost. What if we had the chance to sow the seeds of terrestrial life throughout the universe, to settle young planets within developing solar systems many light-years away, and thus give our long evolutionary line the chance to continue indefinitely? http://www.physorg.com/news184915200.html Space & Earth Tue, 09 Feb 2010 07:34:04 EST news184915200 (PhysOrg.com) -- Google is developing a translator for its Android smartphones that aims to almost instantly translate from one spoken language to another during phone calls. http://www.physorg.com/news184916311.html Technology Tue, 09 Feb 2010 07:33:48 EST news184916311 US technology titans IBM and Intel have rolled out powerful new computer chips designed for businesses continually demanding more from networks and data centers. http://www.physorg.com/news184914384.html Electronics Tue, 09 Feb 2010 05:30:01 EST news184914384 A Utah company plans to dig a series of underground caverns that it hopes to one day fill with compressed air, releasing it to generate electricity by turning a turbine and solving one of the most vexing problems facing the clean-energy industry -- how to store power. http://www.physorg.com/news184913953.html Technology Tue, 09 Feb 2010 05:00:35 EST news184913953 Use of most electronic media is not associated with headaches, at least not in adolescents. A study of 1025 13-17 year olds, published in the open access journal BMC Neurology, found no association between the use of computer games, mobile phones or television and the occurrence of headaches or migraines. However, listening to one or two hours of music every day was associated with a pounding head. http://www.physorg.com/news184882223.html Medicine & Health Mon, 08 Feb 2010 20:13:27 EST news184882223 (PhysOrg.com) -- Resistant wheat plants stave off attacks by Hessian fly larvae by essentially destroying the fly's midgut and its ability to absorb nutrients, according to a study by Purdue University and the U.S. Department of Agriculture. http://www.physorg.com/news184878260.html Biology Mon, 08 Feb 2010 19:04:39 EST news184878260 (PhysOrg.com) -- A team of Brigham Young University engineers and chemists has created an inexpensive silicon microchip that reliably detects viruses, even at low concentrations. http://www.physorg.com/news184876976.html Chemistry Mon, 08 Feb 2010 18:43:24 EST news184876976 Cellular imaging offers a wealth of data about how cells respond to stimuli, but harnessing this technique to study biological systems is a daunting challenge.
