Online payment company PayPal has released a new version of its app for Android and Apple’s iOS operating systems. The company is hoping it will make a big difference in a tricky area: Mobile e-commerce. And Marketplace Tech reporter Queena Kim joins us to play Silicon Tally.

This week Washington is debating the very real possibility of military intervention in Syria, from air strikes to so-called boots on the ground. But there’s another conversation happening around whether the U.S. should attack President Assad’s regime with cyber warfare. So what might a cyber attack against Syria look like, and what would the repercussions be? 

We all know about the data being collected on us by advertisers while we’re online. Serving us ads that are more relevant to our interests? Sure, great. But take the amount of data – and what companies can do with it – to the extreme. Maybe your smart fridge tells a food company when you turn into a Cookie Monster, and suddenly you get a text from a cookie company. There are plenty of possibilities.

Today is a bit of a Kodak moment. At least, the company is hoping for that. Expected to emerge from bankruptcy today, the old camera and film maker has a new focus: a future in printing. And lots of people are logging back into the old campus intranet this week, as students, professors and administrators return to colleges and universities around the country. And you know what that means. We’re starting yet another academic year of campus-wide hacks. Can it all be avoided?

September looks to be pretty busy for tech giant Apple. The company is expected to announce two new iPhones, and maybe more. But it’s safe to say that Apple doesn’t command excitement around releases like it used to. Can the latest product announcements keep Apple on top? And today marks the midpoint of this year’s hurricane season, which means a supercomputer at the University of Texas in Austin is at full steam ahead. It’s being used to input real time weather data from all over the world and to predict extreme weather up to the minute.

A famous peace-keeping technology turns 50-years-old today — the so-called “red phone” that connected Moscow and Washington. The phone apparently wasn’t actually red, but it did change the Cold War. And, it’s time again to play our tech news numbers game, Silicon Tally. Today’s contestant is behind some mobile video games you’ve probably seen before: Farmville and Pac-Man for iPhone, the insanely popular Mafia Wars, and more.

The idea of controlling objects, even other humans, with only your brain is a holy grail of tech innovation. And what researchers did at the University of Washington this month sounds pretty amazing. Using non-invasive technology to record and stimulate brain function, a researcher at one end of campus controlled the physical actions of someone at the other end of campus. And, Twitter makes another move at revenue.

Although its smartphone business is hurting, BlackBerry may spin off its popular messaging service. All this comes as the company could be getting ready to put the whole firm up for sale. And Nissan says it will offer self-driving cars by the year 2020. Google is also in that space. But driverless cars raise unusual new legal issues we really haven’t had to think about before.

In two critical minutes, Nasdaq’s technology failed the world. One hundred and twenty seconds are under scrutiny in the investigation to find out what caused Nasdaq’s giant freeze-up on Thursday after computer problems forced the exchange to halt trading for hours. And the Apple vs. Google war extends to virtual personal assistants.
