This Week in Science: PCOS Becomes PMOS, an 'Impossible' Crystal, And More!

This week's science roundup covered medicine, archaeology, space, and public health.

Researchers proposed renaming PCOS to PMOS to better reflect the condition.

Archaeologists dated Scotland's Loch Bhorgastail crannog to more than 5,000 years ago, while scientists identified an unusual crystal in Trinity test material.

Other studies linked retinal aging to osteoporosis risk, improved NASA Mars helicopter rotor design, and found an association between cannabis use disorder and major depression.
