Fiery food and femme fatales

Hot enough for ya? July’s scorching temperatures notwithstanding, there are still some people who can’t get, or sweat, enough. The new series “Heat Seekers” (9 p.m., Food) scours the 50 states for America’s most fiery foods and the folks who cook and eat them.

Hosted by chefs Aaron Sanchez and Roger Mooking, “Heat” kicks off in Chicago, where a place called Hot Doug’s serves something called “The Atomic Bomb,” made of pork sausage and jalapeno and habanero peppers. They also attend the Super Painful Pizza Challenge. Contestants are given 10 minutes (and a glass of water) to devour a 10-inch pizza covered in jalapeno and Scotch bonnet peppers.

• As the recent Casey Anthony trial proved yet again, people are fascinated by the alleged presence of evil in female form. The obsession with the Anthony verdict and the resulting outrage has been blamed on 21st-century Internet and social media, as well as good old-fashioned 20th- century media and the feral antics of cable news hosts. But that’s simply a case of new media taking credit, or blame, for everything. The emotions inspired by the Anthony trial would not be out of place in 1940s movies like “Leave Her To Heaven” or “Double Indemnity.” And they perfectly echo the late 19th century’s fixation on Lizzie Borden.

“Deadly Women: Killer Countdown” (8 p.m., ID) asked fans of the 2-year-old series to vote for their “top 10” list of female murderers, a lineup they’re calling “the worst of the worst.” Not entirely content to allow the audience to call the shots, expert and psychological profiler Candice DeLong offers distinctions between criminals and their crimes, between the emotionally distraught and the calculating “femme fatale.”

• Speaking of entertainment cliches disguised as news, “20/20” (8 p.m., ABC) devotes two whole hours to stories about people with “super powers.” Not to be confused with a puff piece hyping summer movies about superheroes, this report includes a man who ran 50 marathons in 50 days; another who survived 72 minutes exposed on the North Pole wearing nothing but shorts; and a man with a “super brain” who learned Icelandic, a formidably difficult language, in just one week.
