Scientists have, for the first time, observed one of the natural mechanisms underlying the regulation of the levels of growth inhibiting hormone in plants. This mechanism had been hitherto seen...

Coumarin compounds from oak barrels could contribute to bitter taste in wine and spirits

3 years ago from Physorg

Wine and spirits are complex mixtures of flavor and aroma compounds, some of which arise during aging in wooden barrels. Among other compounds, oak wood releases coumarins, but how they...

Mystery about cause of genetic disease in horses

3 years ago from Physorg

Warmblood fragile foal syndrome is a severe, usually fatal, genetic disease that manifests itself after birth in affected horses. Due to the defect, the connective tissue is unstable. Under force,...

Scientists uncover key process in the manufacture of ribosomes and proteins

3 years ago from Physorg

Researchers at the University of Toronto have shown that an enzyme called RNA polymerase (Pol) II drives generation of the building blocks of ribosomes, the molecular machines that manufacture all...

Bacteria with a metal diet discovered in dirty glassware

3 years ago from Physorg

Caltech microbiologists have discovered bacteria that feed on manganese and use the metal as their source of calories. Such microbes were predicted to exist over a century ago, but none...
