Climate change poses severe impacts on and risks to agriculture, food, and nutrition, particularly for smallholders. Agricultural researchers are tasked with deciphering interconnected variables—from soil characteristics and nutrient cycles to water and biodiversity—to create a robust framework for technological advancements.

Editor’s summaryDNA polymerases, like most enzymes, are specific for their native substrates, deoxyribonucleotides, and have carefully tuned active site chemistry that can be challenging to adapt. Lelyveld et al. performed time-resolved x-ray crystallography on a DNA polymerase variant that accepts a 3′-amino sugar, catalyzing the formation of phosphoramidate linkages instead of the natural phosphodiester bonds.

Evolution Prehistory of neuronsThe disc-shaped aggregates of cells called placozoans are among the most basal of animals. IMAGE: SEBASTIÁN R. NAJLE/CENTER FOR GENOMIC REGULATIONOpen in viewerFree-living marine placozoans are considered the simplest animals on Earth. Their bodies resemble a disk and consist of six to nine cell types. They move by ciliary beating, consume food particles through engulfment, and reproduce by fission. However, Najle et al.

AbstractSeveral experts have warned about artificial intelligence (AI) exceeding human capabilities, a “singularity” at which it might evolve beyond human control. Whether this will ever happen is a matter of conjecture. A legal singularity is afoot, however: For the first time, nonhuman entities that are not directed by humans may enter the legal system as a new “species” of legal subjects.

PHOTO: LEV DOLGACHOV/ALAMY STOCK PHOTOOpen in viewerThe discrimination and harassment faced by women scientists in the West have been increasingly discussed and debated in recent years; however, the challenges faced by women researchers in non-Western contexts remain underexplored. This week on the Science podcast, Aashima Dogra and Nandita Jayaraj examine how gender intersects with other identities and with social expectations in India’s scientific community.

Although trustees and administrators at universities in the United States are acutely aware of the mental health crisis on their campuses and consistently rate it as one of the most pressing challenges, it usually only gets attention when a tragedy strikes a member of the student body. Those moments illuminate the lack of adequate mental health care for undergraduate and graduate students, but are hastily followed up with meetings admonishing administrators to hire more counselors.
