(PhysOrg.com) -- Software packages that interoperate while providing online users with an overview of their colleagues' work may finally threaten the dominance of email as the world's premier collaboration tool. http://www.physorg.com/news176731593.html Technology Fri, 06 Nov 2009 12:07:11 EST news176731593 All of life is founded on the interactions of millions of proteins. These are the building blocks for cells and form the molecular mechanisms of life. The problem is that proteins are extremely difficult to study, particularly because there are so many of them and they appear in all sizes and weights. http://www.physorg.com/news174833488.html Biology Thu, 15 Oct 2009 13:59:41 EST news174833488 Molecules vital to life have been detected in outer space and isolated in meteorites and comets. Some of this material that rained down on Earth may have jump-started biology. If so, these space seeds also may have planted a particular molecular orientation, or "handedness," that spread to the world's first creatures. New research is studying how this handedness could arise in space. http://www.physorg.com/news172502439.html Space & Earth Fri, 18 Sep 2009 14:30:01 EST news172502439 (PhysOrg.com) -- In 1953, Stanley Miller filled two flasks with chemicals assumed to be present on the primitive Earth, connected the flasks with rubber tubes and introduced some electrical sparks as a stand-in for lightning. The now famous experiment showed what amino acids, the building blocks of proteins, could easily be generated from this primordial stew. But despite that seminal experiment, neither he nor others were able to take the next step: that of showing how life`s code could come from such humble beginnings. http://www.physorg.com/news168875229.html Biology Fri, 07 Aug 2009 14:47:47 EST news168875229 MicroRNAs are single-stranded snippets that, not long ago, were given short shrift as genetic junk. Now that studies have shown they regulate genes involved in normal functioning as well as diseases such as cancer, everyone wants to know: What regulates microRNAs? http://www.physorg.com/news160417049.html Medicine & Health Fri, 01 May 2009 17:17:57 EST news160417049 Cells have two chances to fix the same mistake in their protein-making process instead of just one - a so-called proofreading step - that had previously been identified, according to new research. http://www.physorg.com/news156087023.html Biology Thu, 12 Mar 2009 14:30:55 EST news156087023 A new theory as to how galaxies were formed in the Universe billions of years ago has been formulated by Hebrew University of Jerusalem cosmologists. The theory takes issue with the prevailing view on how the galaxies came to exist. http://www.physorg.com/news151766798.html Space & Earth Wed, 21 Jan 2009 13:27:07 EST news151766798 (PhysOrg.com) -- A simple and reliable method for converting one of the simplest chemical entities into one of the most difficult-to-make molecular building blocks of life, with complete control over its shape, is reported by scientists at the University of Bristol in this week's Nature [11 December]. http://www.physorg.com/news148138547.html Chemistry Wed, 10 Dec 2008 13:35:47 EST news148138547 Why is it that the origins of many serious diseases remain a mystery? In considering that question, a scientist at the University of California, San Diego School of Medicine has come up with a unified molecular view of the indivisible unit of life, the cell, which may provide an answer. http://www.physorg.com/news139743407.html Medicine & Health Thu, 04 Sep 2008 10:36:47 EST news139743407
