In vino veritas: Promiscuous yeast hook up in wine-making vats Posted: 26 Feb 2012 08:01 PM PST Humans aren't the only species that like to get busy with a glass of bubbly. Turns out, the common baker's yeast has indulged in a frenzy of amorous frolicking in the fermentation vats of winemakers for hundreds, possibly thousands, of years, with interesting results.

Ancient arabic writings help scientists piece together past climate Posted: 26 Feb 2012 07:59 PM PST Ancient manuscripts written by Arabic scholars can provide valuable meteorological information to help modern scientists reconstruct the climate of the past, a new study has revealed. The research analyses the writings of scholars, historians and diarists in Iraq during the Islamic Golden Age between 816-1009 AD for evidence of abnormal weather patterns.

Elusive platelet count and limb development gene discovered Posted: 26 Feb 2012 12:35 PM PST Researchers have identified an elusive gene responsible for Thrombocytopenia with Absent Radii (TAR), a rare inherited blood and skeletal disorder. As a result, this research is now being transformed into a medical test that allows prenatal diagnosis and genetic counseling in affected families.

Glow and be eaten: Marine bacteria use light to lure plankton and fish Posted: 26 Feb 2012 12:35 PM PST Not all that glitters is gold. Sometimes it is just bacteria trying to get ahead in life. Many sea creatures glow with a biologically produced light. This phenomenon, known as bioluminescence, is observed, among others, in some marine bacteria which emit a steady light once they have reached a certain level of concentration (a phenomenon called "quorum sensing") on organic particles in ocean waters.

Scientists score new victory over quantum uncertainty Posted: 26 Feb 2012 12:35 PM PST Uncertainty affects the accuracy with which measurements can be made in quantum physics. To reduce this uncertainty, physicists have learned to "squeeze" certain measurements. Researchers are now reporting a new type of measurement that can be squeezed to improve precision.
