Microfluidic models of the CNS: Understanding cells, circuits & synapses. Aims: We aim to develop new cell culture platforms to form defined networks of brain cells. These platforms will be used to determine the critical mechanisms underpinning central nervous system function.
Significance: The devices developed will enable an unprecedented capacity to monitor changes throughout a network, with analysis at the level of the synapse, cell and circuit.
Expected outcomes: We will advance knowledge ....Microfluidic models of the CNS: Understanding cells, circuits & synapses.

Flexibility in the timing of parturition: the key to viviparity in lizards? Embryos of viviparous lizards usually gain adequate nutrients from yolk. Why then has placentotrophy evolved in some species, and what new opportunities has it opened up? The answer may lie in the advantages gained from flexibility in the timing of birth, made possible by supplementary transfer of storage lipids to embryos during gestation. We argue that this provides a pivotal opportunity for evolutionary divergence: so ....Flexibility in the timing of parturition: the key to viviparity in lizards? Embryos of viviparous lizards usually gain adequate nutrients from yolk. Why then has placentotrophy evolved in some species, and what new opportunities has it opened up? The answer may lie in the advantages gained from flexibility in the timing of birth, made possible by supplementary transfer of storage lipids to embryos during gestation. We argue that this provides a pivotal opportunity for evolutionary divergence: some alpine species exploit flexible parturition; other species replace optional placentotrophy with obligate transfer. Our unique experimental approach, using two well-researched clades of viviparous skinks, will result in new testable hypotheses about the evolution of viviparity.Read moreRead less
