Human problems rarely occur in a vacuum, but persist as part of ongoing social interaction in which causes and effects are interwoven. One person's behavior can set the stage for what another does. A new study in the journal Family Process reveals that smoking can promote emotional connection for couples when both partners smoke. Health-compromising behaviors, such as smoking or weight gain, may sometimes persist because they preserve stability in a vital close relationship. http://www.physorg.com/news156007421.html Medicine & Health Wed, 11 Mar 2009 16:24:50 EST news156007421 Moths need just the essence of a flower's scent to identify it, according to new research from The University of Arizona in Tucson. http://www.physorg.com/news155472320.html Biology Thu, 05 Mar 2009 10:45:53 EST news155472320 (PhysOrg.com) -- A University of Arizona research team recently completed a study looking at the DNA blueprint of almost 1,000 individuals and comparing that to detailed measurements of their hair, skin and eye color. http://www.physorg.com/news155239299.html Chemistry Mon, 02 Mar 2009 18:03:01 EST news155239299 (PhysOrg.com) -- The patterns of missing asteroids are like the footprints of wandering giant planets preserved in the asteroid belt. http://www.physorg.com/news154802620.html Space & Earth Wed, 25 Feb 2009 16:44:17 EST news154802620 (PhysOrg.com) -- Researchers from the University of Arizona have created a fluid-based opthalmic lens in which the amount of fluid can be constantly adjusted to provide customized eye correction. The lens may one day be incorporated into the tools that eye doctors use to determine prescription strength. http://www.physorg.com/news154705159.html Physics Tue, 24 Feb 2009 13:40:08 EST news154705159 Some algae have been hanging together rather than going it alone much longer than previously thought, according to new research. http://www.physorg.com/news154275197.html Biology Thu, 19 Feb 2009 14:13:43 EST news154275197 The 6.7 magnitude earthquake that struck the Los Angeles community of Northridge at 4:30 a.m. on Jan. 17, 1994, killed 57 people, injured more than 5,000, and caused an estimated $20 billion in damage, making it the costliest seismic disaster in U.S. history. http://www.physorg.com/news154119920.html Space & Earth Tue, 17 Feb 2009 19:05:56 EST news154119920 Plants are flowering at higher elevations in Arizona's Santa Catalina Mountains as summer temperatures rise, according to new research from The University of Arizona in Tucson. http://www.physorg.com/news153482329.html Space & Earth Tue, 10 Feb 2009 10:00:41 EST news153482329 (PhysOrg.com) -- Astronomers will use the powerful University of Arizona/Smithsonian MMT Observatory on Mount Hopkins, Ariz., to search for lunar water ice when NASA fires a 2-ton rocket into a polar crater on the moon later this year. http://www.physorg.com/news153152542.html Space & Earth Fri, 06 Feb 2009 14:23:50 EST news153152542 National economies are driven by the automobile, even during an economic downturn. Every day, hundreds of millions of people take their cars to visit remote places, to commute, and to reach the supermarket. http://www.physorg.com/news152881093.html Other Sciences Tue, 03 Feb 2009 11:40:14 EST news152881093 (PhysOrg.com) -- Schrodinger's cat, a macroscopic object that is both alive and dead at the same time, illustrates the strangeness of quantum mechanics. While such quantum properties have been widely observed for electrons and molecules, recent experiments have shown that larger objects may also demonstrate quantum effects. Just how large, though, is still an open question. http://www.physorg.com/news152369994.html Physics Wed, 28 Jan 2009 13:00:43 EST news152369994 (PhysOrg.com) -- Even though scientists have successfully sequenced the human genome, they still lack a clear picture of exactly how coding and non-coding DNA sequences function together, or how genomes evolve over time. This has been particularly problematic for scientists who use genetic similarities to characterize evolutionary divergence. Historically, the processes of genetic evolution and genome degradation have been difficult to study due to technological limitations and lack of accurate historical records for species. http://www.physorg.com/news151260626.html Biology Thu, 15 Jan 2009 16:50:26 EST news151260626 Researchers at The University of Arizona are developing a set of standardized tests that could improve the lives of people with Down syndrome. http://www.physorg.com/news150991781.html Medicine & Health Mon, 12 Jan 2009 14:09:41 EST news150991781 Rocks on Mars are on the move, rolling into the wind and forming organized patterns, according to new research. http://www.physorg.com/news150644809.html Space & Earth Thu, 08 Jan 2009 13:46:49 EST news150644809 At first, figuring out how pebble-sized rocks organize themselves in evenly-spaced patterns in sand seemed simple and even intuitive. But once Andrew Leier, an assistant geoscience professor at the U of C, started observing, he discovered that the most commonly held notions did not apply. http://www.physorg.com/news150556841.html Space & Earth Wed, 07 Jan 2009 13:20:41 EST news150556841
