First at 6:00 tonight, WXDU's science show, The Endless Frontier, will take a look at a new study on the effects of artifical sweeteners on the microbiome, the bacteria that inhabit the human gut. The hosts will also examine new information about stem cell therapy and regenerative biology.

Next at 6:30, With Good Reason explores the roots of rock 'n' roll, race in imaginings of the South, dialects and education, and "Affrilachian" poetry. Host Sarah McConnell begins with a discussion of Sister Rosetta Tharpe, the "Godmother of Rock 'n' Roll." Next, she examines the portrayal of the problem of racism in Brodway plays and how teachers can deal with students who speak in dialects rather than standard English. Finally, McConnell talks about Affrilachian poetry as it celebrates its 20th anniversary.

Then at 7:30, Lincoln Wensley has WXDU Sports. Lincoln will have a wrap-up of the Duke men's football season so far, as well as analysis of the team's future this fall. He'll have comments from the team before they played last weekend's game against Miami and a recap of that match-up. Lincoln will also talk about what the Blue Devils have in store for next week's contest against Georgia Tech.
