Cancer's origin story features predictable plot line, researchers find sumedicine nature

deficiency elicits a temporally defined order of genomic aberrations raises the possibility that these features may similarly predict progression to CIN GC. Future evaluation of this hypothesis will require annotated intestinal metaplasia tissue collection with long-term follow-up.

By joint measurement of lineage, CNAs and transcriptional states in individual cells, we investigated the molecular basis of clonal expansions and fitness. This showed stringent selection and reproducible subclonal dynamics across replicate cultures in which the same, initially rare, subclone fixed in the population.

Detecting temporal and spatial malaria patterns from first antenatal care visits - Nature CommunicationsDetecting temporal and spatial malaria patterns from first antenatal care visits - Nature CommunicationsPregnant people visiting antenatal clinics may represent a useful sentinel surveillance population for monitoring infections such as malaria. Here, the authors investigate the potential of this approach by comparing malaria prevalence in pregnant people and children living in the same area of southern Mozambique.

Drug reinforcement impairs cognitive flexibility by inhibiting striatal cholinergic neurons - Nature CommunicationsDrug reinforcement impairs cognitive flexibility by inhibiting striatal cholinergic neurons - Nature CommunicationsAddictive substances may impair cognitive flexibility. Here the authors show that in rodents, increased activity of striatal direct-pathway medium spiny neurons (dMSNs) in response to cocaine inhibits cholinergic interneurons (CINs), reducing cognitive flexibility.
