▲ Abstract：

Using a dataset of 41.3 million research papers across the natural sciences and 学网covering distinct eras of AI, here we show an accelerated adoption of AI tools among scientists and consistent professional advantages associated with AI usage, but a collective narrowing of scientific focus. Scientists who engage in AI-augmented research publish 3.02 times more papers, receive 4.84 times more citations and become research project leaders 1.37 years earlier than those who do not. By contrast, AI adoption shrinks the collective volume of scientific topics studied by 4.63% and decreases scientists’ engagement with one another by 22%. By consequence, adoption of AI in science presents what seems to be a paradox: an expansion of individual scientists’ impact but a contraction in collective science’s reach, as AI-augmented work moves collectively towards areas richest in data. With reduced follow-on engagement, AI tools seem to automate established fields rather than explore new ones, highlighting a tension between personal advancement and collective scientific progress.

▲ Abstract：

Here we applied deep learning methods to genome alignments from 22 divergent placental mammal species to infer the evolution of the recombination landscape. We identified a large and 学网evolutionarily conserved X-linked recombination desert constituting 30% of the chromosome. Recombination-aware phylogenomic analyses from 94 species revealed that the X-linked recombination desert is an ancient and recurrent barrier to gene flow and retains the species history when introgression dominates genome-wide ancestry. The functional basis for this supergene is manifold, enriched with genes that influence sex chromosome silencing and reproduction traits. Because the locus underpins reproductive isolation across ordinal lineages, it may represent a reliable marker for resolving challenging relationships across the mammalian phylogeny.

▲ Abstract：

Here we reveal that the conserved mitochondrial Hsp70 co-chaperone, Mge1, acts as a stress messenger in budding yeast. During mitochondrial stress, unimported Mge1 entered the nucleus and triggered the transcription of mitoCPR target genes. This was mediated by the interaction of Mge1 with the transcription factor Pdr3 on DNA regulatory elements. The mitochondrial targeting sequence of Mge1 was both sufficient and essential for mitoCPR induction, demonstrating that in addition to their roles in mitochondrial protein import, targeting sequences can also function as signalling molecules. As protein import defects are a common consequence of various types of mitochondrial damage, these findings suggest a novel function for the targeting sequence of Mge1 as an indicator of mitochondrial health.

▲ Abstract：

Here, to comprehensively characterize its genomic landscape and the clinical significance of genomic characteristics, we analysed whole-genome sequences from 1,364 clinically annotated breast cancers, with transcriptome data available for most cases. Our study expands the repertoire of oncogenic alterations and identifies novel driver genes, recurrent gene fusions, structural variants and copy number alterations. Timing analyses on copy number alterations suggest that genomic instability emerges decades before tumour diagnosis, and offer insights into early initiation of tumorigenesis. Pattern-driven genomic features, including mutational signatures2, homologous recombination deficiency3, tumour mutational burden and tumour heterogeneity scores4, were associated with clinical outcomes, highlighting their potential utility as predictive biomarkers for clinical evaluation of treatments such as CDK4/6 and HER2 inhibitors, as well as adjuvant and neoadjuvant chemotherapy. These findings highlight the power of large-scale, clinically annotated whole-genome sequencing in advancing our understanding of how genomic alterations shape patient outcomes.

▲ Abstract：

Here we report an extreme barocaloric effect in NH4SCN aqueous solutions enabled by pressure-tuned dissolution and precipitation. This mechanism delivers an exceptionally large cooling capacity and markedly enhanced cooling efficiency. We obtain an in situ temperature drop of 26.8?K in the solution at room temperature, surpassing all known caloric materials. A Carnot-like cycle is designed to deliver 67?J?g?1 cooling capacity per cycle with a second-law efficiency of 77%, benefiting from the extremely large temperature drops and direct heat transfer due to the self-circulating aqueous solution. Beyond the phase-transition scenario, this dissolution-based approach that combines the merits of current leading technologies emerges as a promising sustainable refrigeration solution.
