A close-up look at the action of space weathering on carbonaceous asteroids, provided by Ryugu’s returned samples, highlights its role on the dehydration of the first micrometre-thick layer of the surface, possibly hiding a water-rich interior. The depth of the 2.7 µm hydration band may be an indication of the level of space weathering withstood by a C-type asteroid.

Many tumours are heterogenous, which calls into question whether multiple biopsies are required to accurately assess the cancer. Here, the authors show that papillary renal cell carcinoma is clonal in nature, suggesting that in this cancer one biopsy is sufficient for diagnosis and molecular analyses.

Chromosome 8q24 is known to be a major susceptibility region for prostate cancer risk. Here the authors analyze genetic data across the 8q24 region from 71,535 prostate cancer patients identifying 12 risk loci, three previously unreported, highlighting the contribution of germline variation at this locus.

Roger Milne and colleagues conduct a genome-wide association study for estrogen receptor (ER)-negative breast cancer combined with BRCA1 mutation carriers in a large cohort. They identify ten new risk variants and find high genetic correlation between breast cancer risk for BRCA1 mutation carriers and risk of ER-negative breast cancer in the general population.

Vaccines against the WA1 SARS-CoV2 strain confer protection against other variants. However, the mechanisms underlying cross-protection are not fully understood. Here, the authors develop a method for rapid analysis of single B cells from patient samples and show that infection with a variant elicits convergent, public B cell responses to other variants.

A new class of hybrid metal-organic materials that exhibit magnetic ordering well above room temperature is presented. Although a precise structural model for these materials has yet to be elucidated, the versatility of their solution-based synthesis route suggests that it should be possible to prepare a wide range of analogous magnets.
