Article Synopsis
- Primary nectar-robbers create multiple holes in flowers, bypassing reproductive organs, which raises questions about why robbed flowers continue to attract foragers despite signaling low nectar availability.
- Three hypotheses were tested regarding this behavior, with findings showing that multiple holes appeared in flowers even before all had been robbed, and that foragers return to previously robbed flowers days later.
- The study concluded that older flowers provide more nectar value than younger ones, explaining why bees prefer to rob older, previously damaged flowers, thus revealing patterns in nectar-robbing activity.

In bacteria, the preference of the central ribonucleases RNase E, RNase J and RNase Y for 5'-monophosphorylated RNAs is considered important for RNA degradation. For RNase E, the underlying mechanism is termed 5' sensing, contrasting to the alternative 'direct entry' mode, which is independent of monophosphorylated 5' ends.

This requires efficient targeting systems that recognize N-terminal signal sequences in client proteins and deliver them to protein transport complexes in the membrane. While the importance of these protein transport machineries for the spatial organization of the bacterial cell is well documented in multiple studies, the contribution of mRNA targeting and localized translation to protein transport is only beginning to emerge.
