Most living angiosperms (flowering plants) are pollinated by insects, and the new reconstruction of the ancestral pollination mode of angiosperms suggests that their most recent common ancestor was also insect pollinated.

Small-scale battery-like microbial fuel cells are a promising alternative power source for future low-power electronics. Controllable microbial electrocatalytic activity in a miniaturized microbial fuel cell with unlimited biodegradable energy resources would enable simple power generation in various environmental settings. However, the short shelf-life of living biocatalysts, few ways to activate the stored biocatalysts, and extremely low electrocatalytic capabilities render the miniature microbial fuel cells unsuitable for practical use. In new research, heat-activated Bacillus subtilis spores are revolutionarily used as a dormant biocatalyst that can survive storage and rapidly germinate when exposed to special nutrients that are preloaded in the device.
