AI program can diagnose skin cancer "as well as doctors"

An AI algorithm can diagnose malignant skin lesions "as accurately as a group of 21 certified dermatologists," per Bloomberg.

  • How it works: Researchers at Stanford used an algorithm already developed by Google, but trained it to "visually diagnose potential cancer" from almost 13,000 images of skin disease, per a Stanford news report. To test the algorithm, 21 dermatologists were shown over 370 images of skin lesions and asked if "they would proceed with biopsy or treatment, or reassure the patient." The algorithm performed as successfully as the dermatologists.
  • Why it matters: Early detection of skin cancer is important in reducing health risks, and Bloomberg reports that the AI may be able reduce how many surgeries patients need.
  • Biopsies, however, are still the most reliable "means of detection," and real-life doctors and nurses "outperform AI" in assigning treatments and spotting symptoms.

A New York Times spokesperson said in a statement Thursday that the paper will be changing its editorial board processes after a Wednesday op-ed by Sen. Tom Cotton (R-Ark.), which called for President Trump to "send in the troops" in order to quell violent protests, failed to meet its standards.

Why it matters: The shift comes after Times employees began a coordinated movement on social media on Wednesday and Thursday that argued that publishing the op-ed put black staff in danger. Cotton wrote that Trump should invoke the Insurrection Act in order to deploy the U.S. military against rioters that have overwhelmed police forces in cities across the country.
