Parasexual recombination in cancer cells

Within a colony that originates from a single hybrid cell and is formed by spontaneous fusion of differentially labelled breast cancer cells, most cells maintain the expression of both parent-specific fluorescent markers. However, a subset of cells lost the expression of the green marker, with some cells migrating away from the colony, suggesting subclonal diversification within the progeny of the hybrid clone.

    At 50, the Convention on Wetlands (Ramsar, 1971) has a mixed legacy. To survive and stay relevant in the Anthropocene, the convention will need to embrace new ecological thinking and conservation approaches.

    Natural selection does not disappear with age, according to a new evolutionary demographic model. This conclusion is at odds with the widespread belief that ending reproduction relaxes purifying selection on alleles that increase our ageing body’s vulnerability to diseases such as cancer, Alzheimer’s or diabetes.

    This Review highlights how information from archaeology, history, palaeoecology and other past sources can, and should, be used to inform plans to enhance the sustainability and resilience of our societies.

    Ecosystems that exhibit long periods of transient dynamics pose particular challenges for management because state shifts can occur in the absence of exogenous drivers. In this Perspective, the authors outline how different transient behaviours can be influenced by management actions, and how understanding their causal mechanisms can guide future mitigation strategies.
