Refinement of a technique for collecting and evaluating the osmolality of haemolymph from Drosophila larvae

This study refines methods for collecting and measuring haemolymph osmolality in Drosophila larvae, concluding the true value is approximately 306.0 mOsm kg-1.

Temperature-dependence and genetic variation in resource acquisition strategies in a model freshwater plant

This study examines how heat stress affects genetic variation in resource acquisition traits in duckweeds, finding increased R* values and reduced genetic variation under high temperatures.

Range expansion is both slower and more variable with rapid evolution across a spatial gradient in temperature

This study shows that range expansion is slower and more variable with rapid evolution across a temperature gradient, challenging current theory about predictability.

Pan-cancer organoid validation of tumor outlier chromosomal amplification events

The paper validates oncogenic chromosomal amplification events across multiple cancers using organoid models and functional assays.

Variation in adaptation across geographic ranges is consistent with strong selection in marginal climates and legacies of range expansion

This study uses transplant data to show that populations at geographic range edges have varying adaptation levels, with poleward edges showing lower fitness and equatorial edges showing higher fitness relative to foreign populations.

Progenitor identification and SARS-CoV-2 infection in long-term human distal lung organoid cultures

This paper develops a feeder-free organoid culture system for human distal lung progenitors and demonstrates SARS-CoV-2 infection of club cells in a novel in vitro model.
