  摘要：Dryland expansion causes widespread water scarcity and biodiversity loss. Although the drying influence of global warming is well established, the role of existing drylands in their own expansion is relatively unknown. In this work, by tracking the air flowing over drylands, we show that the warming and drying of that air contributes to dryland expansion in the downwind direction. As they dry, drylands contribute less moisture and more heat to downwind humid regions, reducing precipitation and...

  摘要：An accommodating and supportive environment is essential to conducting scientific research. Yet, in almost every country, researchers can experience harassment, threats, prosecution, or even violence for opinions they express or for their work in relation to high-profile issues. Although many international and regional reports on this issue are patchy in terms of comprehensiveness and representation, they reveal clear and worrying trends-namely, that researchers working in politically charged ...

  摘要：Errors in chromosome segregation during cell division (mitosis) can lead to chromosomal instability, a hallmark of human cancer. These mitotic errors give rise to the formation of micronuclei-small cytoplasmic structures that are spatially separated from the primary nucleus and contain lagging chromosomes or chromosome fragments. Unlike the primary nucleus of a cell, micronuclei frequently undergo irreparable rupture and collapse. This breakdown releases micronuclear DNA into the cytosol, caus...

  摘要：Humans, dolphins, and elephants are the only known species that vocally label their conspecifics. It remains unclear whether nonhuman primates share this ability. We recorded spontaneous phee-call dialogues between pairs of marmoset monkeys. We discovered that marmosets use these calls to vocally label their conspecifics. Moreover, they respond more consistently and correctly to calls that are specifically directed at them. Analysis of calls from multiple monkeys revealed that family members u...
