Necesitățile energetice și impactul ecologic nbsp;nbsp;nbsp;nbsp;
Producția, transportul și exploatarea energiei ndash; toate au un impact mare asupra mediului și a ecosistemelor. Din păcate, energia are aproape întotdeauna un impact negativ asupra mediului, de la dezastre ecologice directe, cum ar fi vărsarea petrolului, ploile acide și emisiile radioactive, la efectele indirecte, precum încălzirea globală ...

Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

AAA+ protein unfoldases—the Moirai of the proteome
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...
