IMO it’s weird and probably irresponsible to teach bioinformatics without some nod to the group dynamics that shaped (otherwise inexplicable) things like the GFF file format or the Gene Ontology. Not to mention why tools back then had names like BLAST and FASTA,but now are named after cuddly animals

and if we imagine that the increase in the number of projects submitted may also be due to the use of AI, we will end up with an AI evaluating an AI 🫣

Not sure why @lpachter.bsky.social did not post this here. But it is brilliant. Single cell genomics finally makes it to the clinic.

One of the curiosities of genomics history is that James Watson was vehemently against cDNA sequencing (for ESTs), and fought with Craig Venter & Bernadine Healy who championed it. Tl;dr Watson ended up resigning from the HGP, Venter plowed ahead... and we now have #scRNAseq.

Fig. 1. Dynamic sex variability - An integrative, multidimensional framework. A framework that centers sex variability will enable the study of sex across multiple levels of biological analysis (colored boxes). A) Visual schematic representing the degree of sex variability (y-axis) across biological scale (x-axis) and time (z-axis), with example sex variables of interest (not all possible covariates and functional relationships are presented). In this example, to decipher mechanisms linking gonadal hormones to receptive reproductive behavior in adult rodents (lordosis), the functional relationships (black subset of possible gray relationships) between select variables (bold words) need to be identified. At each level of analysis, numerous variables differ across sex to contribute to reproductive behavior through these functional interactions. Importantly, the degree of variability across sex categories is dynamic and is affected by developmental stage, experience, and environment.

Fig. 2. Approaches for the statistical analysis of sex-associated traits. Flow chart of example approaches for analyzing datasets with sex-associated variables. These analyses answer questions about whether and how sex-associated variables explain variation in dependent variables of interest, how independent variables of interest explain variation in dependent sex-associated variables, and how sex-associated variables (within and/or across levels of analysis) relate to one another. The examples match those in the text where possible, but the approaches are widely applicable and flexible. The choice(s) of analyses should follow directly from the research question(s), and it is likely that multiple approaches will be used in the analysis of an integrative dataset.

Fig. 3. Questions for evaluating frameworks and approaches which study sex variability and diversity. Here, we present a set of questions to ask when critically evaluating work (whether it is your own or others) that addresses sex diversity and variability. Note that these questions reflect the integration of the conceptual framework, experimental approaches, and analysis and interpretation, as each of these aspects informs the other.

Long live sex diversity & variability!

Meet the team of EU-SABV!
This is a group of researchers with a special interest of including sex as a biological variable into their work.
For the next 4 years, this team will work to enhance current SABV policy in preclinical research!

Fantastic review on the importance of rigorous experimental design. Amen. 😊

For example many people would think that you need to double the number of animals if you plan an experiment including both sexes and want to keep statistical power... Which is actually not true

Yes, we will discuss experimental design and power issues. Even for bioinformaticians, it's important to be able to weigh in on a discussion about study design!

One challenge is to analyze the data rigorously, for example extract significant interactions between sex and other factors of interest. Another is to then interpret the results (e.g., no significance doesn't always mean there is no effect, maybe the experiment is underpowered...)
