- Decreasing cloud cover drives the recent mass loss on the Greenland Ice Sheet
Reduction in summer cloud cover over the Greenland Ice Sheet is the main driver of recent melt.
- Modified human crania from Göbekli Tepe provide evidence for a new form of Neolithic skull cult
Carved and drilled skull fragments from a circa 11,000-year-old ritual site point to an undocumented variation of skull cult.
- Comment on “Marine plastic debris emits a keystone infochemical for olfactory foraging seabirds” by Savoca et al.
DMS odors on plastic debris may not explain plastic ingestion by seabirds.
- HIV virions sense plasma membrane heterogeneity for cell entry
HIV virions target co-receptors and fuse at ordered/disordered domain boundaries in cholesterol-rich plasma membranes.
- Dependence of drivers affects risks associated with compound events
Compound extremely hot and dry summers become more frequent with higher CO2 concentrations due to stronger interdependence.
