Science Cafe Concord meets Tuesday, Oct. 17, to discuss all the various ways that detection, treatment and even cures for cancer are changing due to breakthroughs in immunotherapy and genetics. As always, it’s free and starts at 6 p.m. at The Draft Sports Bar, 67 S. Main St., Concord.

The  Piscataqua Science Cafe starts up again next week, too – with a discussion about the future of right whales in the north Atlantic, cleverly titled “Right Whales in the Wrong Places.” It’s at the Portsmouth Brewery, 56 Market St., starting at 6 p.m. on Wednesday, Oct. 18.
