Return to Rudimentary Medicine
Abraham Verghese, a professor at the Stanford University School of Medicine, offers surprising reasons for why C.T. scans should not replace the ritual of doctors examining patients' bodies.
Abraham Verghese, a professor at the Stanford University School of Medicine, tells the story of a woman brought into the E.R. for respiratory problems. In an earlier era, doctors would have performed a physical examination to make a diagnosis, but the woman was given a C.T. scan directly. The result? The scan showed tumors in her breasts and cancer throughout her body. Rather than praise the abilities of the C.T. machine, however, Verghese says its omnipresence has allowed doctors to become complacent—a thorough physical examination should have detected her tumors and other cancer-related symptoms long before.

Neuroscience research suggests it might be time to rethink our ideas about when exactly a child becomes an adult.
- Research suggests that most human brains take about 25 years to develop, though these rates can vary among men and women, and among individuals.
- Although the human brain matures in size during adolescence, important developments within the prefrontal cortex and other regions still take pace well into one's 20s.
- The findings raise complex ethical questions about the way our criminal justice systems punishes criminals in their late teens and early 20s.
Does believing in true love make people act like jerks?
- Ghosting, or cutting off all contact suddenly with a romantic partner, is not nice.
- Growth-oriented people (who think relationships are made, not born) do not appreciate it.
- Destiny-oriented people (who believe in soulmates) are more likely to be okay with ghosting.
A new method of growing mini-brains produces some startling results.
- Researchers find a new and inexpensive way to keep organoids growing for a year.
- Axons from the study's organoids attached themselves to embryonic mouse spinal cord cells.
- The mini-brains took control of muscles connected to the spinal cords.
