Humans can infer rules for building words in a new language from a handful of examples, and linguists also can infer language patterns across related languages. Here, the authors provide an algorithm which models these grammatical abilities by synthesizing human-understandable programs for building words.

Poaching undermines the effectiveness of marine protected areas, where enforcement capacity is limited. In this study, fishers adjacent to MPAs were surveyed, and it was found that about half had observed poaching, but that most do not react so as to avoid conflict, or because they feel that this is either not their responsibility or that poaching is a survival strategy.

Mitochondria contribute to metabolic adaptation in cells exposed to environmental challenges. Here, the authors identify a signaling cascade that regulates the lifespan of mitochondrial mutant animals grown on distinct diets.

A large-scale field intervention experiment on 23,377 US Facebook users during the 2020 presidential election shows that reducing exposure to content from like-minded social media sources has no measurable effect on political polarization or other political attitudes and beliefs.

The eROSITA bubbles and their surrounding regions are best described by the same two-temperature model, implying that the shells are bright because they are denser, not hotter. Also reported are non-solar Mg/O and Ne/O ratios, which support the stellar-feedback origin of the bubbles.

A transiting planet with a period of about 8.5 days and a radius 0.4 times that of Jupiter is reported within the debris disk around the star AU Microscopii.

Theories of human categorization have traditionally been evaluated in the context of simple, low-dimensional stimuli. In this work, the authors use a large dataset of human behavior over 10,000 natural images to re-evaluate these theories, revealing interesting differences from previous results.

The warm Earth-sized planet LHS 475 b is validated and characterized with two transits observed by the JWST. The absence of evident spectroscopic features excludes a substantial hydrogen envelope and indicates that LHS 475 b has either little or no atmosphere or an optically thick cloud deck at high altitudes.

The bankruptcy of 23andMe was an inflection point for the direct-to-consumer genetics market. Although the privacy of consumer data has been highlighted by many as a concern, we discuss another key tension in this case: the corporate enclosure of scientific data that has considerable potential value for biomedical research and public health.
