GBE | A Chromosome-Level Genome Assembly and Resequencing Data Reveal Low DNA Methylation and Reduced Diversity in the Solitary Bee Pollinator Osmia cornuta

Möllmann, @eckartstolle.bsky.social et al. report the first genome assembly for the European orchard bee and investigate its epigenomic architecture to find evidence for the limited role of methylation in gene regulation in Hymenopterans.

Molecular evolution of dietary shifts in ladybird beetles (Coleoptera: Coccinellidae): from fungivory to carnivory and herbivory - BMC Biology Background Dietary shifts are major evolutionary steps that shape ecological niches and biodiversity. The beetle family Coccinellidae, commonly known as ladybirds, first transitioned from a fungivorou...

Hello bluesky world! Newbee here! I have a postdoc position immediately available in my lab. It will focus on identifying high-quality transposons in many genomes and finding their impacts in evolution and traits. Most works, including EDTA2 development and annotation of 400+ genomes, are done! 1/n

Study finds strongest evidence yet that shingles vaccine helps cut dementia risk Older adults in Wales who had the jab were 20% less likely to be diagnosed with dementia that those not vaccinated Researchers who tracked cases of dementia in Welsh adults have uncovered the strongest evidence yet that the shingles vaccination reduces the risk of developing the devastating brain disease. Health records of more than 280,000 older adults revealed that those who received a largely discontinued shingles vaccine called Zostavax were 20% less likely to be diagnosed with dementia over the next seven years than those who went without.

Estimated additive genetic variance organized by 143 traits. Colored ridges show the estimated additive genetic variance across 100 permutations for either MOA bQTL (green), bgSNPs (orange), and remaining genome SNPs (purple). Black symbols represent the mean estimated value across permutations. Traits arranged by bQTL mean variance estimates and color coded according to general trait groupings: vitamin E metabolites = navy blue, metabolites = purple, stalk strength = light blue, flowering time = gold, plant architecture = red, disease = green, tassel architecture = pink, ear architecture = orange, misc. = grey.

I still love this figure. Submitting revisions this week. SNPs in transcription factor binding sites (green) explain the majority of additive genetic variation for >70% of ~150 phenotypes (rows) in maize. See Alt for detailed figure legend. See www.biorxiv.org/content/10.1... for more!

Check out this impressive potato genome (graph) study, with @zbao.bsky.social as co-first author! I especially liked the authors' idea of a 'broken window' effect of deleterious SVs, which seem to attract more deleterious mutations (SVs and SNPs) nearby.
