Using a combination of automated behavior recording and sophisticated mathematical analyses, the international team of researchers showed for the first time that such variability cannot be due to simple random events but is generated spontaneously and non-randomly by th...

Hives ferment a yeasty brew, attract beetle pest

...ure, perhaps bees bring it into the hive." This combination of domestic honeybees, small hive beetles and yeast produced IPA leads to combs so messy that the bees eventually decide to abandon the hive, leaving the beetle larvae to consume all the stored food, reproduce and multiply. "If beekeepers can reve...

Each combination can have either an inhibiting or an activating effect on the downstream neuron and, in addition to this, can differ in its intensity and reaction time. The entirety of all possible networks of a defined dynamics resembles a complex figure in a multid...
