Pathologic mandibular prognathism, or “Habsburg jaw” is a deformity where the lower jaw outgrows the upper jaw. In other words the person has a big chin. It most famously appeared in the Habsburg family, but it exists in the bloodlines of many other royal families of Europe, perhaps first appearing in Vlad the Impaler!

Sexism and Lobotomies

Unfortunately, and unsurprisingly, women were disproportionately given lobotomies during the psychiatric procedure’s heyday. From the 1940s through the mid-1950s, men slightly outnumbered women as patients in American state hospitals, yet female patients made up about 60 percent of those who underwent lobotomy. Many psychiatrists believed it was easier to return women after operation to a life of domestic duties at home than it was to post-operatively rehabilitate men for a career as a wage earner.

Conservators Concerned About Plastic

But not for reasons you think! Early plastics are beginning to degrade. It is so bad that venues have been having to remove plastic historical items from display because they are visibly deteriorating. Historians have many advanced chemical and biological techniques to preserve artifacts but they are for “traditional” artifacts which are made from natural materials – wool, wood, iron – not man-made materials. 

Now conservators are having to quickly discover new techniques to keep plastic artifacts from deteriorating, techniques that work on materials which have never before had to be conserved. It is apparently a huge challenge!

Climate Change Causing Ice Thaws, Which Reveals Prehistoric Artifacts — And Threatens Them:

Climate change is uncovering exciting archaeological artifacts, especially near the Arctic Circle where items lost in the snow for millennia are being exposed as the snows melt away. But by being revealed, ancient relics are suddenly exposed to sunlight, oxygen, and rain.

Archaeologists are racing to find and preserve artifacts before nature destroys them…

Prehistoric farmers in what is today China had two main crops: millet in the north, rice in the south, and a vast middle region of mixed farming.

You should absolutely look at this map in high-resolution because there is a lot going on. It shows the northermost limit of rice cultivation and the southernmost limit of millet cultivation, possible centers of the domestication of each, and shows archaeological sites where rice, millet, or both were grown in prehistoric times.
