Hey, it’s the 23rd issue (already) of Iserotope Extras! This week’s articles run the gamut: (1) how mothers are self-identifying; (2) how students in Chicago are fighting back against the firing of their school librarian; (3) how prison guards in New York mistreated a dying inmate; and (4) how teenagers are broadcasting their endless hours of hanging out. Enjoy!

An Inmate Dies, and No One Is Punished

Several of you may have read this disturbing article. The 2010 death of Leonard Strickland would have probably been forgotten by all but the officers and inmates at Clinton Correctional Facility. Then a breakout brought attention to the prison’s secrets. (Warning: Don’t watch the video.)

YouNow, a live-streaming social network, is making stars

Move over YouTube. Everyone (well, at least teenagers) are on YouNow now. Which means: They’re hanging out, sitting around, talking—all online, for hours and hours.
