Study Finds Large-Scale Tornado Outbreaks Increasing

A new study suggests Chicago gun violence could be contagious; a surprisingly simple way to boost interest in STEM education; the survival of many apes and monkeys is in doubt; and a surprising reason tornado outbreaks are on the rise.

Rabiah Mayas, director of science and integrated strategies at the Museum of Science and Industry, returns to talk all things science with Eddie Arruza.

What we’re talking about:

• Yale researchers say that after studying gun violence in Chicago they have created a model that can predict how “contagious” violent outbreaks will be.

• It’s good to talk. Researchers find that parents who talk to high schoolers about the importance of science see their ACT scores improve.

• Some 60 percent of non-human primates are now under threat of extinction and 75 percent are suffering a population decline.

• Large tornado outbreaks are on the rise but climate change may not be the culprit.
