CNN Radio News Day: February 21, 2013 by CNN published on 2013/02/21 21:34:39 +0000 Welcome to CNN Radio News Day. It's been one week since model Reeva Steenkamp was found dead inside the home of her boyfriend, Oscar Pistorius - the "Blade Runner" Olympian. He remains in jail on the charge of premeditated murder. Today's court hearing was adjourned until Friday with no decision yet on bail. CNN's Robyn Curnow says the Prosecution suffered a big blow when it was revealed that the lead police investigator was facing attempted murder charges himself in another case: "The police actually say they knew about it, but they were letting justice take its course. A media report came out today exposing this and that's when they acted - and acted quite quickly. He's been removed from the Oscar Pistorius case and one of the country's top detectives has been put on to lead this case now. " It's been almost a week now since a meteor crashed in Russia, shattering windows around a 50-acre area. Some 1,200 people were injured, mostly from flying glass. That meteor was relatively small compared to other space rocks that are orbiting in our solar system - ones that could potentially destroy entire cities. Dr. Bong Wie of Iowa State University is working on a plan to blow up a potentially deadly asteroid: “Our plan is relatively simple. Using a nuclear device and using current spacecraft technology, we will be able to mitigate the impact threat from an asteroid with very short warning time." The phone book celebrates its 135th birthday today. The first one was printed in New Haven, Connecticut on February 21, 1878 - just two years after the telephone was first patented. In the beginning, the phone book wasn't just a list of names and numbers. Ammon Shea is the author of the book "The Curious History of the Book That Everyone Uses But No One Reads": "The November 1878 issue of the telephone book gave these very explicit instructions on what you should say when somebody picks up the phone. You should say 'Hello.' And then when you finish your conversation apparently you were supposed to say 'That is all' and then hang up."
