There is a tendency to think that only men treat women in a sexist way, but a new study by a University of Miami researcher and his daughter shows that both men and women participate in maintaining a gender hierarchy in our society. The study, titled "Social Dominance and Sexual Self-Schema as Moderators of Sexist Reactions to Female Subtypes," was recently published by the journal of Sex Roles. http://www.physorg.com/news177260107.html Other Sciences Thu, 12 Nov 2009 14:55:49 EST news177260107 Standing out in a crowd is better than blending in, at least if you're a paper wasp in a colony where fights between nest-mates determine social status. http://www.physorg.com/news174827689.html Biology Thu, 15 Oct 2009 12:15:46 EST news174827689 The Japan Fair Trade Commission (JFTC) has set its sights on Qualcomm, less than a week after the US wireless technology titan was fined over 200 million dollars by South Korea's antitrust watchdog. http://www.physorg.com/news168021001.html Technology Tue, 28 Jul 2009 17:30:45 EST news168021001 South Korea's antitrust watchdog Thursday fined US firm Qualcomm a record 260 billion won (208 million dollars) for violating fair competition rules by abusing its market monopoly. http://www.physorg.com/news167549766.html Technology Thu, 23 Jul 2009 06:36:46 EST news167549766 Many dogs are put down or abandoned due to their violent nature, but contrary to popular belief, breed has little to do with a dog's aggressive behaviour compared to all the owner-dependant factors. This is shown in a new study from the University of Córdoba, which includes breeds that are considered aggressive by nature, such as the Rottweiler or the Pit Bull. The conclusions, however, are surprising: it is the owners who are primarily responsible for attacks due to dominance or competition of their pets. http://www.physorg.com/news159792962.html Biology Fri, 24 Apr 2009 11:56:20 EST news159792962 (PhysOrg.com) -- When there is a threat of disease during pregnancy, mothers produce less aggressive sons with more efficient immune systems, researchers at The University of Nottingham have discovered. http://www.physorg.com/news150373790.html Biology Mon, 05 Jan 2009 10:29:50 EST news150373790 (PhysOrg.com) -- When there is a threat of disease during pregnancy, mothers produce less aggressive sons with more efficient immune systems, researchers at The University of Nottingham have discovered. http://www.physorg.com/news149347543.html Medicine & Health Wed, 24 Dec 2008 13:25:43 EST news149347543 A new study in the journal Personal Relationships reveals that women prefer mates who are recognized by their peers for their skills, abilities, and achievements, while not preferring men who use coercive tactics to subordinate their rivals. Indeed, women found dominance strategies of the latter type to be attractive primarily when men used them in the context of male-male athletic competitions. http://www.physorg.com/news148735298.html Medicine & Health Wed, 17 Dec 2008 11:21:38 EST news148735298 A team led by Craig Pikaard, Ph.D., WUSTL professor of biology in Arts & Sciences, has made a breakthrough in understanding the phenomenon of nucleolar dominance, the silencing of an entire parental set of ribosomal RNA genes in a hybrid plant or animal. http://www.physorg.com/news147632722.html Biology Thu, 04 Dec 2008 17:05:22 EST news147632722 Unlike the male-dominated societies of their chimpanzee relatives, bonobo society -in which females enjoy a higher social status than males -has a "make-love-not-war" kind of image. While chimpanzee males frequently band together to hunt and kill monkeys, the more peaceful bonobos were believed to restrict what meat they do eat to forest antelopes, squirrels, and rodents. http://www.physorg.com/news143124062.html Biology Mon, 13 Oct 2008 13:41:02 EST news143124062 It is known that the phonic structure of calls produced by males during the breeding season may signal quality-related characteristics in many different types of animals. Previous research on mammals has mainly focussed on the relationship between the acoustic components of vocalizations and one aspect of male quality: body size. http://www.physorg.com/news139625986.html Biology Wed, 03 Sep 2008 01:59:46 EST news139625986 Female monkeys are more dominant when they live in groups with a higher percentage of males. This is caused by self-organisation. This surprising discovery was made by researchers at the University of Groningen. What makes the study particularly interesting is that the researchers used a computer model which can simulate interaction between monkeys. Their findings will be published on July 16 in the open-access journal PLoS ONE. http://www.physorg.com/news135403061.html Biology Wed, 16 Jul 2008 04:57:41 EST news135403061
