DNA replication is tightly regulated to ensure that one accurate copy of each chromosome is inherited by two daughter cells1. Replication start sites (origins) are activated in temporally separated steps2,3,4,5, which are under the control of three classes of protein kinase. These include DDK ...

The carbon isotope-delta scale is defined by the virtual material Vienna Peedee belemnite (VPDB). Since 2005, the VPDB scale has been defined by assigning consensus values of −46.6 ‰ to LSVEC lithium carbonate and +1.95 ‰ to NBS 19 calcium carbonate [57, 58]. Before a proper ...

Carbon monoxide (CO) is an indispensable C1 building block. For decades this abundant gas has been employed in hydroformylation and Pausen-Khand catalysis, amongst many related chemistries, where a single, non-coupled CO fragment is delivered to an organ
The response of carbonate weathering carbon-sink flux (CCSF) to its environmental drivers is still not well understood on the global scale. This hinders understanding of the terrestrial carbon cycle. Here, we show that there is likely to be a widespread
