Finally! I missed the last one, but I'm desperate to go back!

Ready for it???
To all the **sex determination lovers**
📢 Save the date to the 10th International Symposium on the Biology of Vertebrate Sex Determination (VSD) held in the beautiful Hawaii!!
Great community, amazing science, excellent speakers and superb location 🏝

Huge congratulations to Dr. @awood2.bsky.social on her successful defense!!! So proud of you and all you've accomplished!

I'm counting hundreds of tiny green dots, streaming triple j's "like a version" and pretending I'm still in Adelaide (where it is now summer, and things and wonderful).

Weaned and ear-tagged some PWD mice recently (if you know, you know how...energetic they can be). Parents were bouncing off the walls, but the babies are perhaps the sweetest little mice I've ever met.

The sex binary is dead!
Long live sex diversity & variability!

Sex is one of the greatest sources of variation seen in life. How do we advance the scientific study of sex across the animal kingdom? Read our latest article in Hormones & Behavior to find out!

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.

Should I go to Ithaca's premature Trans Day of Remembrance? Probably. Will I? No. Why? Because I am trash.

Very sad/upset about leaving NM a week early, never having made it to Las Cruces. A handful of days in Albuquerque was not sufficient; I need to come back asap.

I'm getting frustrated at how heavily my research relies on antibodies, yet how few quality antibodies are actually available. There has to be a better way.

Why did I ever stop studying monotremes? Easily a top 5 lifetime regret.
landismj.bsky.social Michael Landis @landismj.bsky.social · Aug 31
Early work found no REM in sleeping echidna, suggesting REM sleep arose in other mammals after diverging from monotremes. Later work discovered REM in the only other living monotreme genus. What do platypuses look like when dreaming, you ask?
