Ecological & Evolutionary Functional Genomics, mostly butterflies. Biology Professor, Stockholm University.

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.

The extensive and unique Art Nouveau in Helsinki constantly enchanted me during my > 4 years as an ECR there, but I didn’t read up on their architects like I should have. Here’s a fresh intro piece on Eliel Saarinen: Beguiled by the Dreamy Streetscapes of Helsinki www.nytimes.com/2026/07/31/t...

Beguiled by the Dreamy Streetscapes of Helsinki

A writer goes in search of the architect Eliel Saarinen, whose Art Nouveau-inspired designs helped shape early-1900s Finland as well as midcentury America.

Mismapping of sequencing reads from polymorphic duplications generates spurious … everything. Regions of the genome that assemble well, map well .. are usually those not interesting for the polymorphic traits many of us are chasing. Below .. human studies see spurious effects upon trans-eQTLs

Avocados come in 2 varieties - A-types start each day female and switch to male midday. B-types do the reverse. In work just published from the last chapter of my PhD, we show this system evolved 40+million yrs ago and is regulated by alleles of 1 transcription factor www.pnas.org/doi/10.1073/...

In avocado and certain wild relatives in Lauraceae, a highly synchronized daily rhythm of floral sex timing promotes cross-pollination between two ...

Ethnic cleansing of 100s of 1000s of people who have lived in the USA as legal, productive neighbors for over a decade Will harm them & the communities they've helped keep vital White supremacist ideologues want white Americans to believe this will help us It's a dirty, harmful lie

Maybe the Biggest Problem With A.I. Is People: Lots here resonates w me, “working with A.I. requires us to get better at what the best managers have always done. ... Leadership 101 .. are now skills everyone needs .. Try asking your A.I. agent how you frustrate it.” www.nytimes.com/2026/07/24/o...

Opinion | Maybe the Biggest Problem With A.I. in the Workplace Is People

Learning to use A.I. effectively at work is all about using the same tried-and-true skills we use to be a better manager and collaborator.

Excited to share the SNPstar! preprint! 🌿 SNPstar helps researchers explore how natural variation in Arabidopsis thaliana affects protein structure and function by integrating SNP data, AlphaFold3 models, stability predictions, population context, and more. www.biorxiv.org/content/10.6...

SNPstar: A Web Server Linking Allelic Variation to Protein Structure and Function in Arabidopsis thaliana

Understanding how natural genetic variants affect protein structure and function is central to plant biology. The 1001 Genomes Project has catalogued millions of single nucleotide polymorphisms (SNPs)...

Tim Janicke, Göran Arnqvist and colleagues have a new paper out discussing how biological sex is rooted in anisogamy (different gamete sizes) and how this relates to broader evolutionary patterns of sex-specific selection. You can read more about it here: onlinelibrary.wiley.com/doi/10.1111/...

Biological Sex Is Binary and Rooted in Anisogamy

Drawing on empirical evidence and evolutionary theory, we argue that biological sex is most coherently defined as a binary classification of reproductive strategies rooted in anisogamy (the productio...

Thanks! I personally didn’t look at those, but much of the stock is currently being used in a large field expt (2nd year now!). They’re quantifying herbivory and will look at glucosinolates down the line. A related study from the lab on ~30 species found some cool macro level differences

Variation in herbivore defense strategies among plant species differing in elevational distribution and the role of temperature in defense

Temperature influences the distribution and performance of both plants and insect herbivores. Consequently, plant–herbivore interactions are likely to vary across thermal gradients, which could affe...
