(PhysOrg.com) -- A new scientific study has found that at least some of the stereotypes associated with older siblings are true: the oldest sibling is often less trusting, less cooperative, and less reciprocating than younger siblings. http://www.physorg.com/news179568469.html Medicine & Health Wed, 09 Dec 2009 08:18:43 EST news179568469 (AP) -- The United States ranks near the bottom in life expectancy among wealthy nations despite spending more than double per person on health care than the industrialized world's average, an economic group said Tuesday. http://www.physorg.com/news179497953.html Medicine & Health Tue, 08 Dec 2009 12:33:08 EST news179497953 Rice University evolutionary biologists David Queller and Joan Strassmann argue in a new paper that high cooperation and low conflict between components, from the genetic level on up, give a living thing its "organismality," whether that thing is an animal, a plant, a bacteria - or a colony. http://www.physorg.com/news176990429.html Biology Mon, 09 Nov 2009 12:06:53 EST news176990429 Bee colonies are well known for high levels of cooperation, but new research published in Molecular Ecology demonstrates a conflict for reproduction between worker bees and their Queens, leading some workers to selfishly exploit the colony for their own needs. http://www.physorg.com/news171746038.html Biology Wed, 09 Sep 2009 21:20:01 EST news171746038 Rewards go further than punishment in building human cooperation and benefiting the common good, according to research published this week in the journal Science by researchers at Harvard University and the Stockholm School of Economics. While previous studies have focused almost exclusively on punishment for promoting public cooperation, here rewards are shown to be much more successful. http://www.physorg.com/news171206724.html Medicine & Health Thu, 03 Sep 2009 14:25:58 EST news171206724 (PhysOrg.com) -- Animal societies are hotbeds of conflict and cooperation, with creatures helping each other one moment and fighting the next. Biologist Andrew Zink has developed a new theoretical framework that helps explain why these societies stay together and remain peaceful in the face of conflict over resources. http://www.physorg.com/news165769569.html Biology Thu, 02 Jul 2009 16:20:01 EST news165769569 Why do humans cooperate in things as diverse as environment conservation or the creation of fairer societies, even when they don`t receive anything in exchange or, worst, they might even be penalized? http://www.physorg.com/news135580478.html Other Sciences Fri, 18 Jul 2008 06:14:38 EST news135580478
