John attends a school for people with special needs and loves to watch Sesame Street in his free time. Identical twins like Sam and John pose an important question for scientists: How can a disorder that is known to be highly genetic look so different in siblings who share the same genome?

After the Hamas attack of Oct. 7 triggered Israel's invasion of the Gaza Strip, hundreds of thousands of Palestinians began fleeing from the North of Gaza to the South. As they fled, many Palestinians reported passing through checkpoints with cameras. Israel had previously used facial recognition software in the West Bank, and some Palestinians reached out to The New York Times reporter Sheera Frenkel to investigate whether the same was happening in Gaza. 

Science correspondent Geoff Brumfiel talks to Frenkel about how Israel launched this facial recognition system in Gaza late last year with the help of private companies and Google photos.
