Tuesdays Best Bets on TV

"NOVA: scienceNOW" (8 p.m., PBS): Can NASA satellite imagery uncover hidden sites of ancient Mayan ruins? Will space elevators (hoisted by a 22,000-mile-long cable) make it possible someday to vacation in orbit? And what's the word on the so-called Bacteria Whisperer, a researcher who has found a language that nearly all bacteria use to communicate -- with huge implications for developing new antibiotics? These reports are part of the January edition of "NOVA scienceNOW." And as if all that weren't enough, another report tells how scientists are tapping genetic codes for insight into human aging, with the possibility of reengineering them to extend the human life span. The one-hour science magazine is hosted by Neil deGrasse Tyson.
"Really Big Things" (8 p.m., Discovery Channel): Waiting for "the big one"? Gigantic, humongous, mammoth items are on display in "Really Big Things." Host Matt Rogers shows viewers the super-size versions of machines, structures and other massive man-made marvels.
"People's Choice Awards" (9 p.m., CBS): Queen Latifah is your host for the most populist of awards shows -- the 33rd annual People's Choice Awards. This is the one where folks like you determine our favorites in television, music and the movies. Latifah is also a nominee for "favorite funny female star."

"Most Deadly" (10 p.m., Discovery Channel): This new series is about disastrous events as varied as plane collisions, bridge collapses and serial killing sprees. The program includes interviews with those who survive the experiences, plus a forensic breakdown of the causes and how the events may have changed the world.
"Anti-Semitism in the 21st Century: The Resurgence" (10 p.m., PBS): More than 60 years after the Holocaust, violent acts against Jews and Jewish institutions continue.
