When it comes to returning the sense of hearing to people who are deaf or hard of hearing, technology is far from perfect. Hearing aids can feed back. And there are other problems, but this week there’s been a leap forward in one particular area. Cochlear implants; a new processing computer chip for these implants has been developed at MIT’s Microsystems Technology Laboratory and the Massachusetts Eye and Ear Infirmiry. Meanwhile, of all the industries being disrupted by technology, the music business might be undergoing the most change. But one thing that has not changed dramatically is music education … yet. Marketplace’s David Weinberg travelled to new Orleans to bring us the story of a new tool that connects students with American master musicians.

This week, Target executives have been answering questions about the hack that resulted in the theft of personal data from tens of millions of people. But while that story continues to develop, there’s something else to consider. Far from credit card and phone numbers, what about all the information in our health records? Turns out a lot of those records aren’t very secure, and might be even more valuable to hackers. And, what do Super Bowl leftovers, hook-up apps, and Steve Ballmer have in common? They’re all part of Silicon Tally this week. Our guest, Molly Mullshine, writes about tech for the website Beta Beat, and joined us to play.

The winter olympics start Tomorrow in the Russian city of Sochi. Olympians, officials, and reporters have been arriving all week with lots of devices in tow. And that means there’s been a lot of talk about digital surveillance. Russia’s government doesn’t have the best record in, say, protecting freedom of the press. Plus, YouTube used to be a place that was mostly about curiosities, bits of original, unedited video clips by amateurs. Then people started getting serious. The amateurs started getting famous because of what — and how much — video they were putting on the website. YouTube started selling ads on all those videos and giving some of that money to creators. But as one New York Times reporter found out, it can still be hard to make the big bucks even when you’re a super YouTuber.

Ahh, Twitter. Newly minted as a public company. Valued at some $30 billion. But also about to enter that routine that can be painful for a big company of any kind. The quarterly earnings report. At best, Twitter’s revenue plan might be called…still emerging. And, here’s a place you wouldn’t expect to find an award-winning app: A cattle farm in Scotland. The application is, yes, for cattle management. It was designed by teenagers as part of a contest put together by an organization called Apps for Good. 

Every year on my birthday, I’m amazed to discover how many people on Facebook remember. Thanks guys. Well today, some people might be posting well wishes on Facebook’s wall. The social network turns 10 years old today. And for a little 10-year-old, it’s had some major impact on our online lives. And this week, the wearable tech company Pebble launched it’s app store, offering downloads like Yelp notifications that will appear on your smartwatch. But there’s a problem: Battery life. As wearable technology grows, our battery power will need to grow too.

Today Facebook releases a new mobile application called Paper. It doesn’t really look a lot like Mark Zuckerberg’s crowded, blue social network. But, it is part of his empire, and it might help the company keep building engagement by not looking like … Facebook. Also, some of the newer high-valued companies in Silicon Valley these days are more focused on sharing with your business partners than sharing with your friends. Example: Box helps people and businesses share documents and other data on the cloud. And the young company privately filed for an IPO a few days ago.

It might be number 48, but this weekend’s football game is being called the first mass transit Super Bowl. The game will not be played in downtown Manhattan, but in East Rutherford, New Jersey. And with a Met Life stadium capacity of about 82,000 a lot of technology is being leveraged to actually get the fans to the game via public transportation.

All this week, Marketplace Tech has been talking about sports and technology for our “Gaming the System” series. Today, we take you to a hockey rink right about the spot that A-Rod usually stands — that’s right, Yankee Stadium. On the eve of a big outdoor hockey game at New York’s Yankee Stadium, we find out how the NHL is converting a baseball field to a hockey arena.

This month, a neuroscientist and his team announced that the ceremonial first kick at this year’s World Cup opening in Brazil would be completed by a paralyzed teenager using an exoskeleton attached to her brain. Prosthetic robotic devices connected to the human brain are becoming more common. You may remember video a few years ago of a woman at the University of Pittsburgh feeding herself chocolate with a robot limb. For today’s installment of Marketplace Tech’s sports and tech series, “Gaming the System,” we’ll hear from a guy working in this field.
