‘Nova’ looks at progress of science

Tonight’s must-see

PBS’ “Nova ScienceNow,” 9 p.m., KSPS channel 7. How much can science do?

Can it determine which Van Gogh painting is a fake? Predict our health future via DNA? Create an artificial tree, pulling carbon dioxide from the air.

We see fascinating efforts at all three. We also get a profile of Partis Sabeti. An Iranian native, she survived tough times to become a rising geneticist – and a part-time rock star.

Tonight’s must-see II

“So You Think You Can Dance,” 8-10 p.m., Fox. This show keeps getting better. Great choreography merges with gifted individuals - and some impressive duos.

Watch the link between Joshua Allen, 19, a beefy Texan, and Katee Taira Shean, 20, a Californian. Catch Kherington Payne, 18, a California blonde, and Will Wingfield, 21, a Debbie Allen protege from Nashville.

Eventually, they’ll have to compete against each other. For now, they’re magical together.

Other choices include

“Happy Feet” (2006, 6:30 p.m.) and “Harry Potter and the Order of the Phoenix” (2007, 8:30 p.m.), HBO. This is a good time for family viewing. Here are two choices, one animated and one epic.

“Criminal Minds,” 9 p.m., CBS. Young black women are being killed in a mostly white suburb. The team scrambles to find the killer.
