Fair enough. Next up - what is a gene.

Surely that answers your question! A definition of a locus that doesn’t consider linkage might not be that meaningful!

Excited to soon start my new role as Academy of Finland Research Fellow 🦋🐛I’ll later be advertising a PhD position on tiger moth colour and genomics, and will be speaking at #ESEB2025 this week if you want an idea of what’s going on!

While helping out on a cool genomics project recently, I came to realise I’d been taught a pretty big inaccuracy about the events that occur at fertilization. I suspect that almost everyone reading this has the same misapprehension, so let’s do some learning together: 1/

This seems to be exactly the case right up until you need to grow them to feed to caterpillars. Then they seem to change their tune.

Very lucky to be at UCSF with such great microscopy facilities. These instruments are definitely pushing the limits of what we thought feasible in live imaging! Excited to keep exploring how these single cells organize and secrete such precise morphologies.

If you've ever wanted to know what the actin filaments on the scales in a developing moth wing look like in 3D, here you go!

Kyle DeMarr from @mullinslab.bsky.social acquired these beautiful data on the single objective light sheet at the UCSF Center for Advanced Light Microscopy.

🚨Postdoc opportunity🚨: LepEU postdoc: comparative population genomics of European scale adaptation in butterflies

2 year, full-time PD in my group, Stockholm Univ.

Applications assed on rolling basis, deadline: 23 August 2025. Planned start 1 Oct.

Details:
christopherwheatlab.wordpress.com

The aim of this proposal is to place population genomic insights into a comparative framework to gain fundamental insights into the determinants of evolutionary outcomes. The project will work within LepEU, the European Lepidopteran Population Genomics Consortium (https://lepeu.github.io/). LepEU provides access to field samples from European populations of diverse species. Chromosome-scale reference genomes are provided by Project Psyche (https://www.projectpsyche.org/). Networking during the postdoc will be facilitated by participation in the 10kLepGenomes COST Action (https://10klepgenomes.eu/). Existing datasets await analysis, while additional samples need DNA extraction and submission for sequencing. Functional validation capability (CRISPR/Cas9 gene manipulations) is also available to test emergent hypotheses of allele-to-phenotype impacts. Personal research interests of the postdoc will be important to determine the exact project, as the project has a generous sequencing budget.

The successful applicant should have a PhD (obtained within 6 years of the application deadline) in a suitable subject area, such as evolutionary biology or population genomics. A strong interest in population genomics, local adaptation, comparative analyses, and experience working with genomic-scale data is essential. The candidate must have a documented publication record demonstrating relevant skills. Experience working with bioinformatic pipelines (e.g., Snakemake), or working with butterflies is welcome but not essential. The net salary is 28,000 SEK/month (~2,430 Euro, not subject to Swedish income tax) and comes directly from the Carl-Trygger Foundation stipend, which is paid out directly to the postdoc. Only PhD candidates acquired outside of the host department can apply. Currently, the lab of Prof. Wheat consists of 3 postdoctoral researchers, while the Dept. of Zoology provides a vibrant and excellent research environment of active, dynamic researchers.

Applications should include: i) a succinct description of research interests and experience, detailing your contribution to any relevant publications (max 1 page), ii) why you are the ideal candidate for this position in the lab (max 1 page); iii) a CV including a list of publications, and iv) the name and contact information of two personal references.

Applications will be reviewed on a rolling basis with a deadline of 23 August 2025. The project is planned to start on 1 October, but flexibility in the starting date can be provided for a suitable candidate. Please contact Prof. Wheat for additional information.

🚨 Super exited to see our paper on the inheritance and genetic basis of guppy color variation come out in @natecoevo.nature.com‬ rdcu.be/eugWV

Guppy males have enormous variation in color patterns, with many combinations of ornamental spots and stripes. But where does all this variation come from?

Embrace that "get through the Ph.D. mindset," know that well-designed science has a chance to succeed, put your head down, and write those grants.

If we don't write grants, there will be an opportunity to justify further cuts to NSF staffing. So, if you don't have optimism, write a spite grant.

A process server delivered a letter regarding my "hostile" and "defamatory" attacks on #ColossalBio co-founder Ben Lamm, insinuating I'm a misogynist and a failed scientist. Nothing I've said is defamation, but you can read it a judge for yourself. I've redacted my home address 1/n
