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.

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

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.
