Bacterial life cycles

Bacteria express a remarkable diversity of life cycles, but studying the organization and evolution of these cycles remains a challenge. Analysis in the phylogenetic group of the Bacilli reveals the modular organization of their life cycle and its evolutionary consequences. One of these life-cycle modules is colony formation, and the colony of one of the most potent colony formers, Bacillus licheniformis, is depicted.

    Use of origins research for political point-scoring is depressingly frequent, but scientists must take what care they can to ensure that their work is not abused.


Comment & Opinion

    Land policies around the world tend to focus on support for agricultural output. We argue that this leads to ineffective public expenditure, environmental harm and missed opportunities for the use of rural resources. Applying thinking centred on ecosystems services to the governance of rural land would secure greater social value.

    A survey of more than 9,000 conservationists in 149 countries reveals that, despite broad diversity in people and ideas, the global conversation community is not divided. Conservation policy will benefit from drawing on this diversity as international negotiations around the post-2020 agenda for conservation proceed.

    Exposing wild-caught eggs to audio playbacks in the lab reveals that avian embryos can communicate predation risk to their siblings before hatching. This prenatal communication, which possibly occurs through vibrational cues, coordinates the developmental trajectories of the clutch.
