In light of what is happening in Kansas, I want to reup this @sciam.bsky.social article on the world's first trans clinic destroyed in Nazi Germany.

Humans are the only primates with a chin – now we finally know why Biologists have debated the reason why Homo sapiens evolved a prominent lower jaw, but this unique feature may actually be a by-product of other traits shaped by natural selection

BHEML makes headlines yet again! Our PI Dr. Noreen von Cramon-Taubadel was interviewed by New Scientist magazine on her work investigating the human chin, which can also be found in her most recent PLOS One publication. Take a look!

Insights from an evolutionary analysis of ape craniomandibular form Humans are unique among primates in possessing a chin, yet it is currently unclear whether the form of the symphyseal region of the mandible where the chin is located is the product of direct selectio...

New paper by PI Dr. Noreen von Cramon-Taubadel and former BHEML postdoc Dr. Lauren Schroeder! The human chin is a unique; investigating why and how it formed helps us to better understand ourselves and our lineage!

3-day snow accumulation forecast with a palette that resets from dark blue to light yellow at the boundary between 4–6 and 6–8 inches accumulation. This over-emphasizes the transition and may cause confusion.

3-day snow accumulation forecast with a palette that resets from dark blue to light yellow at the boundary between 4–6 and 6–8 inches accumulation. This over-emphasizes the transition and may cause confusion.

While we’re being bombarded with weather maps, I thought I’d revisit one of my favorite color palette tricks. Sometimes it’s important to emphasize a boundary, perhaps between moderate (< 6") and severe (>8") snowfall. You could reset the palette, like the NYT, but there’s a better way.

A page from the ebook version of "A Visual Atlas of Skeletal Growth and Development" by Kyra Stull and Heather Garvin. This page features an image of acetabular development from newborn to 17.5 years. Each of the 19 acetabulae shown are yellow 3D models based on CT scans and oriented in lateral views such that the image focuses on the acetabulum. The upper part of the ilium is cropped out in hipbones after the age of 1.5 years. The age labels and title of the image ("Acetabular Development") are light blue boxes with black text. The bottom of the page has the caption "Figure 4.1 Acetabular development, newborn to 17.5 yoa. Lateral views presented at each designated age."

Yesterday I discovered that ChatGPT's PhD-level expertise didn't extend to bird anatomy. This morning I thought, perhaps I was being too hard on the half-trillion-dollar company. Birds are a little weird, anatomically speaking. Let's try something more familiar. A mammal. Behold.
