Smoky off-flavors in cocoa aren't caused solely by smoke
Fermented cocoa occasionally exhibits off-flavors that can compromise the quality of chocolate and other cocoa products. But what causes these undesirable flavors? Researchers at the Leibniz Institute for Food Systems Biology at the Technical University of Munich have now shown that overfermentation of cocoa beans can cause smoky, leathery and cheesy off-flavors. Smoky flavors, therefore, are not necessarily attributable to smoke contamination.

An anomalous return of the Odden ice tongue suggests unusual Arctic conditions
Data from many sources, including NASA, have shown a significant decrease in Arctic sea ice since 1979. However, the processes driving the melting and freezing of sea ice are complex, and fluctuations occur throughout the year. Short-term variations in temperature, winds, ocean convection and water salinity within a certain region can also affect how much ice can reform or melt.
