Using climate to model ancient human migration
Modeling fills gaps in the fossil record of early hominin movement from AfricaClimate shifts orchestrated hominin interbreeding events across Eurasia
Extreme glacial cooling likely led to hominin depopulation of Europe in the Early Pleistocene
Global water use efficiency saturation due to increased vapor pressure deficit
Increases in global ecosystem water use efficiency have stalled since 2001 due to a rising vapor pressure deficit.Science, 381(6657)
Diverse sleep strategies at sea
Findings in marine mammals and birds provide opportunities to explore sleep’s functionsDelftia tsuruhatensis TC1 symbiont suppresses malaria transmission by anopheline mosquitoes
A naturally occurring bacterium of anopheline mosquitoes produces an alkaloid that arrests the development of co-occurring Plasmodium oocytesPervasive within-species spatial repulsion among adult tropical trees
Tropical trees distance themselves from members of the same species more than from other species and more than expected by chance.Science, 381(6653)
Effect of climate warming on the timing of autumn leaf senescence reverses after the summer solstice
Early-season warming hastens onset and late-season warming extends duration of autumn leaf senescence in northern forests.

Language trees with sampled ancestors support a hybrid model for the origin of Indo-European languages
Indo-European languages emerged south of the Caucasus around 8300 years ago, followed by an expansion northward to the Steppe regions.Science, 381(6655)
The precursory phase of large earthquakes
High-time-rate GPS time series have a precursor signal for large earthquake rupture starting approximately 2 hours beforehand.Science, 381(6654)

Large herbivore diversity slows sea ice–associated decline in arctic tundra diversity
Data from a 15-year experiment show that large herbivores mitigate declines in arctic tundra diversity caused by loss of sea ice with warming.

Agricultural expansion raises groundwater and increases flooding in the South American plains
Converting plains to agriculture creates shallow water tables and increased flooding at the subcontinent scale.Science 380(6649)
