Switching to hydrogen fuel could prolong the methane problem princeton NatureComms
emissions pulse to the atmosphere leads to a small transient growth of atmospheric CHwhose effects last for several decades. In the next sections, we focus on how the equilibrium concentrations of tropospheric Hwould respond to scenarios of continuous emissions from an energy system where part of the fossil fuel energy share is replaced by green or blue Hcould either decrease or increase, mainly depending on the Hlost to the atmosphere.
atmospheric burden rises despite the lower fossil fuel use. We assess the critical factors and the main uncertainties in the quantification of this critical HEI. We finally discuss how our results can help better inform policymakers regarding the trade-off associated with different scenarios of hydrogen production and use.

Molecular sensing of mechano- and ligand-dependent adhesion GPCR dissociation - NatureA technique to detect the release of N-terminal fragments of Drosophila adhesion G-protein-coupled receptors (aGPCRs) provides insight into the dissociation of aGPCRs, and shows that receptor autoproteolysis enables non-cell-autonomous activity of aGPCRs in the brain.

Multicopy suppressor screens reveal convergent evolution of single-gene lysis proteins - Nature Chemical BiologyIn contrast to dsDNA phages where multiple genes are involved in programmed host lysis, ssRNA Fiersviridae phages require only a single gene. Here, genome-wide host suppressors of diverse single-gene lysis systems are identified using a high-throughput genetic screen.
