(CNN) – Welcome to CNN Radio News Day. Here's some of the stories we are covering in today's show:

  • Three more people are behind bars today, in connection with the Boston Marathon bombings. All are 19-year-old males – Dias Kadyrbayev, Azamat Tazhayakov, and Robel Phillipos. Charges against the teens suggest they helped the accused bombers and obstructed justice by throwing-out evidence. CNN's Brian Todd that evidence included a backpack filled with fireworks, a jar of vaseline, and a homework assignment:

"They removed that (backpack), at least one of them, put that in a black trash bag and into a dumpster, and that was then taken to a landfill. Investigators later found that backpack in the landfill with those items in it." FULL POST

(CNN) -  Last week, a fake news story got tweeted from a hacked Associate Press twitter account. Within about two minutes, the stock market sunk over 100 points, but then came back to the surface soon afterwards. An event only made possible by the speed and robotic actions of High Frequency Trading.

Much of the quick back-and-forth trading that swings the market up and down is done by computers. Thousands of trades happen every second. It's because companies have created algorithms to scour the web for information on the market and then acts on that information, in the form of automatic trading. FULL POST
