Taking the ‘Shame Part’ Out of Female Anatomy (Published 2021)
Allison Draper loved anatomy class. As a first-year medical student at the University of Miami, she found the language clear, precise, functional. She could look up the Latin term for almost any body part and get an idea of where it was and what it did. The flexor carpi ulnaris, for instance, is a muscle in the forearm that bends the wrist — exactly as its name suggests. Then one day she looked up
Germs in Your Gut Are Talking to Your Brain. Scientists Want to Know What They’re Saying. (Published 2019)
In 2014 John Cryan, a professor at University College Cork in Ireland, attended a meeting in California about Alzheimer’s disease. He wasn’t an expert on dementia. Instead, he studied the microbiome, the trillions of microbes inside the healthy human body. Dr. Cryan and other scientists were beginning to find hints that these microbes could influence the brain and behavior. Perhaps, he told the sc

A Family’s Shared Defect Sheds Light on the Human Genome (Published 2017)
They said it was their family curse: a rare congenital deformity called syndactyly, in which the thumb and index finger are fused together on one or both hands. Ten members of the extended clan were affected, and with each new birth, they told Stefan Mundlos of the Max Planck Institute for Molecular Genetics, the first question was always: “How are the baby’s hands? Are they normal?” Afflicted rel
Scientists Ponder an Evolutionary Mystery: The Female Orgasm (Published 2016)
Evolutionary biologists offered a new way of thinking about the female orgasm based on a reconstruction of its ancient history.Credit...Getty Images An eye is for seeing, a nose is for smelling. Many aspects of the human body have obvious purposes. But some defy easy explanation. For biologists, few phenomena are as mysterious as the female orgasm.

All in all, it was ordinary bariatric surgery — with one big exception. A week before the operation, the man prov
A Pregnancy Souvenir: Cells That Are Not Your Own (Published 2015)
Recently, a team of pathologists at Leiden University Medical Center in the Netherlands carried out an experiment that might seem doomed to failure. They collected tissue from 26 women who had died during or just after pregnancy. All of them had been carrying sons. The pathologists then stained the samples to check for Y chromosomes. Essentially, the scientists were looking for male cells in femal
