To build a cooperative society, is it better to punish or reward?
Superconducting spintronics pave way for next-generation computing
A breakthrough for the field of Spintronics, a new type of technology which it is widely believed could be the basis of a future revolution in computing, has been announced by scientists in Cambridge.
Ultrafast laser helps to better understand high-temperature superconductors
Superconductivity, in which electric current flows without resistance, promises huge energy savings from low-voltage electric grids with no transmission losses, superefficient motors and generators, ...
New study of hunter-gatherers suggests social networks sparked evolution of cooperation
Ancient humans may not have had the luxury of updating their Facebook status, but social networks were nevertheless an essential component of their lives, a new study suggests.
Great balls of evolution: Microbiologists evolve microorganisms to cooperate in new way
University of Massachusetts Amherst microbiologists Derek Lovley, Zarath Summers and colleagues report in the Dec. 2 issue of Science that they have discovered a new cooperative behavior in anaerobic bacteria, known as int ...
New Study Eyes Evolution of Fairness and Punishment
(PhysOrg.com) -- Researchers have long been puzzled by large societies in which strangers routinely engage in voluntary acts of kindness, respect and mutual benefit even though there is often an individual cost involved.
'Pay it forward' pays off
For all those dismayed by scenes of looting in disaster-struck zones, whether Haiti or Chile or elsewhere, take heart: Good acts - acts of kindness, generosity and cooperation - spread just as easily as bad. ...
What is the meaning of 'one'? Evolutionary biologists argue for new meaning of 'organismality'
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," ...
In amoeba world, cheating doesn't pay
(PhysOrg.com) -- Cheaters may prosper in the short term, but over time they seem doomed to fail, at least in the microscopic world of amoebas where natural selection favors the noble.
Carrots are better than sticks for building human cooperation
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 ...
Game theory study: Cooperative behavior meshes with evolutionary theory
(PhysOrg.com) -- One of the perplexing questions raised by evolutionary theory is how cooperative behavior, which benefits other members of a species at a cost to the individual, came to exist.
Scientists open a new window into quantum physics with superconductivity in LEDs
A team of University of Toronto physicists led by Alex Hayat has proposed a novel and efficient way to leverage the strange quantum physics phenomenon known as entanglement. The approach would involve combining ...
Rethinking the roots of altruism
For decades, researchers working to understand how altruistic behavior evolved have relied on a concept known as inclusive fitness, which holds that organisms receive an evolutionary benefit—and are able ...
Chickless birds guard nests of relatives
(Phys.org) —New research has solved a mystery as to why some birds choose not to reproduce, and instead help to guard the nests of their close relatives. This occurs in about nine percent of all bird species.
