Full moon and new moon strains from Roscoff differ in lunar reproductive timing (A). Genotyping of 11 divergent loci (B) in 797 field-caught individuals shows that thetwo timing strains are distinct genetic entities (C).

I'm a fan of the new(ish) Comparative Genome Viewer feature on NCBI: www.ncbi.nlm.nih.gov/cgv which provides interactive whole-genome riparian plots, like this for Helicoverpa sp, which allows you to quickly and easily examine interesting features. Only a handful of genomes on there for now though!
a whole genome riparian plot from the NCBI Comparative Genome Viewer. Two parallel rows; top labelled for Helicoverpa zea, bottom for Helicoverpa armigera. Each row is divided into 31 Chromosomes. Each chromosome is connected by a lines, which correspond to homologous regions. The connecting lines are green to indicate same-orientation homology, and blue to indicate reverse-orientation homology. A zoomed-in view of a small region of Chromosome 24 from the previous figure, with one inversion labelled centrally. Gene tracks are present on both chromosomes.

❄️🧬 Can we generate high-quality reference genomes without the cold chain?

A new study suggests the answer is yes. DNA preserved at room temperature for up to one week produced chromosome-scale reference genomes.

📖 tinyurl.com/3zwtj9ka

#Genomes @gigascience.bsky.social @sangerinstitute.bsky.social
Close-up photograph of a mosquito perched on a green blade of grass against a dark background. White text at the top reads, "Breaking the Cold Chain." Additional text states, "Room-temperature preservation enables chromosome-scale reference genomes." "GigaScience 2026" appears in the lower-right corner. Three researchers collect biological samples in a forest. One researcher kneels while holding a collection tube beside an insulated cooler, and two others stand nearby preparing samples. A large arrow points to the cooler. Text explains that high-quality reference genomes traditionally require specimens to remain frozen from collection through DNA extraction, highlighting the challenge of maintaining the cold chain during fieldwork.

Arctic and Antarctic fish live in waters cold enough to freeze blood.
Many evolved special antifreeze proteins that prevent ice crystals from forming. The surprising part? These proteins evolved independently in different fish lineages on opposite ends of the planet!
#Evolution
Illustration of a fish swimming in front of a globe, representing fish species from opposite polar regions. Two containers labeled "Antifreeze Proteins," one blue and one green, float on either side of the fish. The different colored containers symbolize antifreeze proteins that evolved independently in separate fish lineages living in Arctic and Antarctic waters. The image illustrates convergent evolution, where different organisms develop similar adaptations to survive similar environmental challenges.

🧵 Excited to share my final PhD paper in Ecology Letters!

A classic question in ecology is why some clades contain more species in local assemblages than others.

We argue that part of the answer lies in the timing of speciation itself.

doi.org/10.1111/ele....
Species richness patterns of exemplary clades. (a, c, e) Assemblage species richness (as a proportion of clade richness) of three exemplar avian families (Passerellidae, Dendrocolaptidae & Onychorhynchidae) showing low, intermediate and high levels of co-occurrence across the Americas. Pie charts show clade richness (decreasing in size in order) and the black lines point toward the grid cell of highest richness all in different locations in the Americas. (b) The relationship between clade richness and maximum local species richness (n = 40 families). An ordinary least squares regression estimates an intercept of −0.257 and slope of 0.761. (d) Distribution of maximum (proportional) local species richness across clades, showing large variation between clades.
