| Chimpanzees have police officers, too Posted: 07 Mar 2012 03:50 PM PST Chimpanzees are interested in social cohesion and have various strategies to guarantee the stability of their group. Anthropologists now reveal that chimpanzees mediate conflicts between other group members, not for their own direct benefit, but rather to preserve the peace within the group. Their impartial intervention in a conflict -- so-called "policing" -- can be regarded as an early evolutionary form of moral behavior.  |
| Teaching fat cells to burn calories: New target against obesity involves brown fat Posted: 07 Mar 2012 03:46 PM PST In the war against obesity, one's own fat cells may seem an unlikely ally, but new research suggests ordinary fat cells can be reengineered to burn calories.  |
| First spectroscopic measurement of an anti-atom Posted: 07 Mar 2012 11:54 AM PST Scientists have captured and held atoms of antihydrogen, a single antiproton orbited by a single positron. Now, by measuring antihydrogen's hyperfine structure, they have achieved another first in antimatter science with the very first measurements of the energy spectrum of an anti-atom.  |
| The right type of words: Words spelled on right side of keyboards lead to more positive emotions Posted: 07 Mar 2012 08:27 AM PST Words spelled with more letters on the right of the keyboard are associated with more positive emotions than words spelled with more letters on the left, according to new research by cognitive scientists. Their work shows, for the first time, that there is a link between the meaning of words and the way they are typed -- a relationship they call the QWERTY effect.  |
| Nanotrees harvest the sun's energy to turn water into hydrogen fuel Posted: 07 Mar 2012 08:23 AM PST Electrical engineers are building a forest of tiny nanowire trees in order to cleanly capture solar energy without using fossil fuels and harvest it for hydrogen fuel generation. The team said nanowires, which are made from abundant natural materials like silicon and zinc oxide, also offer a cheap way to deliver hydrogen fuel on a mass scale.  |
| Sperm can do 'calculus' to calculate calcium dynamics and react accordingly Posted: 07 Mar 2012 06:44 AM PST Sperm have only one aim: to find the egg. The egg supports the sperm in their quest by emitting attractants. Calcium ions determine the beating pattern of the sperm tail which enables the sperm to move. Scientists have discovered that sperm only react to changes in calcium concentration but not to the calcium concentration itself. Probably sperm make this calculation so that they remain capable of maneuvering even in the presence of high calcium concentrations.  |
