Morning Roundup: Pass the Liquid Paper edition

Good morning, Houston. These days, when everyone and their dog has a computer, it's getting harder to remember the days when all "official" writing was done on typewriters. The practical modern typewriter was invented in 1868 by an engineer named Christopher Latham Sholes, but it wasn't until 121 years ago today — Sept. 14, 1886 — that George K. Anderson of Memphis got a patent for the typewriter ribbon. They were originally made of cotton and threaded on two spools; way back then, when your ribbon went dry, you sent it back to the factory for re-inking. It makes us happy we learned on a Selectric ... and even more happy that we don't use typewriters anymore.

>> There's something in the air — or is there?: First, janitors claimed Key Middle School had a mold problem. Then, HISD brought in outside investigators to check it out — and they said everything was fine. Now, teachers keep having to be hauled out of the school in ambulances because of breathing problems and mysterious rashes. So what's causing the problems? "Something is making these teachers sick," Gayle Fallon, president of the Houston Federation of Teachers, told KTRK. "They didn't all have a meeting and say, 'Let's fake an illness.'" And yet no one's been able to figure out what's in the air yet: On Wednesday, crews tested the air in 10 classrooms and the hallways and found nothing unusual. HISD Superintendent Abelardo Saavedra said he wants Key to remain open, and city health officials are continuing to monitor conditions.

>> It's 8:30. Do you know where your candidates are?: If you're running for a seat on Houston City Council, you'd want to make sure you lived in Houston, right? Well, of course: Just ask Zafar Tahir and Jack Christie, two candidates who live in the city — but just barely. Both men leased properties inside the city limits in November, just in time to meet legal eligibility requirements, the Chronicle reports. Christie, a Bunker Hill resident, acknowledged that he leased a place in Houston just to meet the requirements, but Tahir — who owns a $200,000 home near the Sugar Land airport — insists that he's really trying to move into a $30,000 condominium near Sharpstown Center in a complex the Chron notes is complete with "damaged blinds, tall weeds and beat-up vehicles." Though Tahir said he stays in the condo most of the time, a neighbor said she rarely sees him or his car. His response? "I don't make a lot of noise." Both men are candidates for the At-Large Position 5 seat.

>> Today's weather: Looks like we're in for a pretty nice weekend: lots of sun, afternoon highs around 90 and overnight lows in the lower 70s. What else is there to say? Go outside and stay there.

But, uh, don't go outside just yet. Read the rest of the news first ...
