Let biological sex be multifaceted, as all biology is. And when you need to be precise in scientific research, be precise. Say ‘gametic sex’ or ‘chromosomal sex’ or ‘anatomical sex’, or whatever is appropriate to your own work.

Point of no returns: researchers are crossing a threshold in the fight for funding
With so little money to go round, the costs of competing for grants can exceed what the grants are worth. When that happens, nobody wins.

"The statistical fragility of animal cognition findings: a meta-meta-analytic reappraisal" doi.org/10.32942/X2Z...
Statistical performance of animal cognition meta-analyses at the primary-study and meta-analysis levels. (a) Statistical power: Median power to detect the (true or bias-corrected) meta-analytic effect size; darker red bars indicate lower power. (b) Type M error: Median exaggeration ratio between estimated and true effect sizes; darker blue indicates stronger overestimation (values > 20 shown as “20+”). (c) Type S error: Median probability of obtaining a significant effect in the wrong direction; darker yellow-green indicates higher Type S error. Violin plots above each panel summarise distributions across meta-analyses. Each point represents one meta-analysis (matching a row in the bar plots), and the horizontal line denotes the overall mean.

Do you get confused when reading meta-analyses? Our new paper offers a practical guide to help researchers understand, interpret, and use them properly. We also show that the insights meta-analyses provide are often overlooked by those who cite them.

Absolutely nobody asked for this but I reformatted my animal yeetability thread into printable poster & zine files. Introducing, the "Pocket Guide to Responsible & Sustainable Animal YEETING" featuring a revamped rating system. Download links below.
Poster showing various animals and their yeetability rating. For full rating, see the link in the reply. Intro text reads:

POCKET GUIDE TO RESPONSIBLE & SUSTAINABLE ANIMAL YEETING
by franzanth

In this context, YEETING is defined as the act of throwing a “projectile” at a slightly upward angle with low initial velocity. The goal here is relocation, not destruction. Therefore, YEETING is ideally performed toward soft surfaces like leaves to minimize downward acceleration that might result in said projectile's discomfort.
