Tick, tock, Jack

Channel surfing the vast cultural wasteland: Kiefer Sutherland returns tonight for a ninth season as counter-terrorism agent Jack Bauer in “24: Live Another Day.”

The franchise may have run out of steam, however, because the 12-part series of two-hour episodes follows Jack second-by-second through a routine day of waiting in line at Starbucks, picking up dry-cleaning and binge-watching episodes of “Game of Thrones.”

Young blood: Scientists say they may have discovered a protein in the blood of young mice that rejuvenates older mice, making them stronger and improving mental function. The researchers say the study may lead to a treatment for humans, but warn it’s not something to be attempted by do-it-yourselfers. “Don’t try this at home,” warned one study author.

It’s just as well. We were having a tough time finding tourniquets and blood transfusion needles tiny enough for our mice.

Don’t know much about history: On this day in 1925, school teacher John T. Scopes was charged with violating a Tennessee state law against teaching evolution. Scopes was found guilty, but his conviction was later set aside.

Unable to prosecute Scopes a second time, Tennessee instead tried the monkey and found it guilty of evolving without a license.
