Darwin suggested that the action of natural selection can produce new species, but 150 years after the publication of his famous book, 'On the Origin of Species', debate still continues on the mechanisms of speciation. New research finds sexual selection to greatly enlarge the scope for adaptive speciation by triggering a positive feedback between mate choice and ecological diversification that can eventually eliminate gene flow between species. http://www.physorg.com/news178458331.html Biology Thu, 26 Nov 2009 14:00:07 EST news178458331 (PhysOrg.com) -- Researchers have found that despite the size zero trend, boys really do prefer 'normal' girls of an average weight and build. http://www.physorg.com/news175866872.html Medicine & Health Tue, 27 Oct 2009 20:10:01 EST news175866872 (PhysOrg.com) -- Whether gazing into lava lamps or watching balsamic vinegar mix with olive oil, people have long been transfixed by the seemingly mystical way that droplets of one liquid find each other within another liquid and join together. Conventional scientific wisdom has held that this merging of liquid droplets, a process called coalescence, is enhanced by applying an electrical field, but a new study, which will be published in the Sept. 17 issue of the journal Nature, shows that an increased electrical field actually can prevent droplets from merging. http://www.physorg.com/news172335053.html Physics Wed, 16 Sep 2009 15:51:31 EST news172335053 (PhysOrg.com) -- New research from The University of St. Andrews in Scotland has discovered that teenage girls are attracted by deep male voices, while younger girls feel intimidated by them. http://www.physorg.com/news172304097.html Medicine & Health Wed, 16 Sep 2009 10:20:01 EST news172304097 (PhysOrg.com) -- Research reported in the Journal of Experimental Social Psychology has shown that men go ga-ga over pretty women. They simply lose their minds (while women keep theirs). http://www.physorg.com/news171536828.html Medicine & Health Mon, 07 Sep 2009 10:07:35 EST news171536828 (PhysOrg.com) -- When it comes to potential mates, women may be as complicated as men claim they are, according to psychologists. http://www.physorg.com/news170331327.html Medicine & Health Mon, 24 Aug 2009 11:15:58 EST news170331327 (PhysOrg.com) -- Proteins are solids. When heated they do not melt; instead, they decompose or sublime directly to the gas phase at low pressures. They cannot be converted into a liquid form unless they are dissolved in a solvent. A team at the University of Bristol (UK) and the Max Planck Institute of Colloids and Interfaces in Golm (Germany) has now successfully liquefied a protein without the assistance of a solvent. As the research team headed by Stephen Mann reports in the journal Angewandte Chemie, the trick is to modify the surface of the protein with a polymeric surfactant. http://www.physorg.com/news169725144.html Chemistry Mon, 17 Aug 2009 10:53:08 EST news169725144 (PhysOrg.com) -- The Milky Way, like many other galaxies, is thought to be embedded in massive, lumpy amounts of dark matter that release gamma rays and other emissions. Although at first these emissions seem too faint to detect, recent observations have shown that they may be stronger than previously thought. In a new study, scientists have developed a model that predicts that gamma rays from hundreds of dark matter clumps should be detectable by the Fermi satellite that was launched in June 2008. http://www.physorg.com/news169121408.html Physics Mon, 10 Aug 2009 11:10:36 EST news169121408 The Casimir force, also known as the Casimir effect, is typified by the small attractive force that acts between two close parallel uncharged conducting plates. Today, this force has become an interdisciplinary subject of study, playing an important role in condensed matter physics, quantum field theory, atomic and molecular physics, gravitation and cosmology, and mathematical physics. Most recently the Casimir force has been applied to nanotechnology. http://www.physorg.com/news168796398.html Physics Thu, 06 Aug 2009 17:10:01 EST news168796398 (PhysOrg.com) -- A team of Yale University researchers has discovered a "repulsive" light force that can be used to control components on silicon microchips, meaning future nanodevices could be controlled by light rather than electricity. http://www.physorg.com/news166711942.html Physics Mon, 13 Jul 2009 13:52:50 EST news166711942 Researchers have found that men and women who feel sensitive to rejection based on their physical appearance are more likely to express interest in having cosmetic surgery than those who are less sensitive to appearance-based rejection. This effect is particularly true when people recall negative comments about their physical appearance. http://www.physorg.com/news165577710.html Medicine & Health Tue, 30 Jun 2009 11:10:01 EST news165577710 Hot or not? Men agree on the answer. Women don't. http://www.physorg.com/news165245639.html Medicine & Health Fri, 26 Jun 2009 15:20:01 EST news165245639 (PhysOrg.com) -- IBM scientists in collaboration with the University of Regensburg, Germany, and Utrecht University, Netherlands, for the first time demonstrated the ability to measure the charge state of individual atoms using noncontact atomic force microscopy. Measuring with the precision of a single electron charge and nanometer lateral resolution, researchers succeeded in distinguishing neutral atoms from positively or negatively charged ones. http://www.physorg.com/news164996346.html Nanotechnology Tue, 23 Jun 2009 17:19:39 EST news164996346 (PhysOrg.com) -- People who feel pressure to look attractive are more fearful of being rejected because of their appearance than are their peers, according to a new study by researchers at the University at Buffalo and the University of Kent. http://www.physorg.com/news162666854.html Medicine & Health Wed, 27 May 2009 18:15:44 EST news162666854 People looking for a good job at a good salary could find their intelligence may not be the only trait that puts them at the top of the pay scale, according to researchers. A new study finds attractiveness, along with confidence, may help job-seekers stand out to employers. http://www.physorg.com/news161527591.html Medicine & Health Thu, 14 May 2009 13:47:12 EST news161527591 (PhysOrg.com) -- UC Riverside biologists researching the behavior of field crickets have found for the first time that female crickets remember attractive males based on the latter`s song, and use this information when choosing mates. http://www.physorg.com/news159637133.html Biology Wed, 22 Apr 2009 16:39:31 EST news159637133 Common sense tells us that when you heat something up it gets softer, but a team of researchers, led by University of Toronto chemistry and physics professor R.J. Dwayne Miller, has demonstrated the exact opposite. Their findings will be published online in the prestigious international journal Science on January 22. http://www.physorg.com/news151856783.html Physics Thu, 22 Jan 2009 14:26:52 EST news151856783 Men with facial scars are more attractive to women seeking short-term relationships, scientists at the University of Liverpool have found. http://www.physorg.com/news146220393.html Medicine & Health Tue, 18 Nov 2008 08:46:33 EST news146220393 (PhysOrg.com) -- Researchers have found that men with strong masculine traits are likely to produce similarly macho sons but, according to the new study by the University of St Andrews, macho sons are not considered especially attractive. http://www.physorg.com/news144513326.html Medicine & Health Wed, 29 Oct 2008 15:35:26 EST news144513326 New research from Aston University in Birmingham, UK suggests that fame really does matter more than beauty when it comes to consumer behaviour. http://www.physorg.com/news137838117.html Medicine & Health Wed, 13 Aug 2008 09:21:57 EST news137838117 Temptation may be everywhere, but it's how the different sexes react to flirtation that determines the effect it will have on their relationships. In a new study, psychologists determined men tend to look at their partners in a more negative light after meeting a single, attractive woman. On the other hand, women are likelier to work to strengthen their current relationships after meeting an available, attractive man. http://www.physorg.com/news135355467.html Medicine & Health Tue, 15 Jul 2008 15:44:27 EST news135355467
