Welcome to this week’s edition of “The Week in Tech,” where we recap some of the most interesting technology and mobile stories from the past week.

This week we cover Hillary Clinton’s candidacy announcement on YouTube, IBM’s Watson Health, Nokia’s purchase of Alcatel-Lucent, and rumors about a Yahoo acquisition of Foursquare.

Hillary Clinton announces bid for presidency on social media

Barack Obama paved the way for technology to play a crucial role in getting voters to the booths on Election Day. Now Hillary Clinton is showing off her tech chops by announcing her candidacy on YouTube.

Before she announced her candidacy, Clinton already hired a Google executive as her tech chief. So it will be really interesting to see how she’ll leverage technology to raise funds, inform the public of her stance, and get voters involved.

IBM creates Watson health

IBM announced that it will partner with Apple, Medtronic, Johnson & Johnson, and others to create a healthcare platform called Watson Health.

Watson Health will combine artificial intelligence with tons of health data to provide recommendations for various diseases and conditions. The system will leverage fitness data from Apple’s HealthKit, and Apple will allow developers to integrate Watson functionality into their apps. Medtronic will leverage Watson software to create personalized treatment plans for diabetic patients, and Johnson & Johnson will use Watson to better communicate with patients.

The virtual doctor will see you now.

Nokia buys Alcatel-Lucent

Nokia has agreed to acquire Alcatel-Lucent for $16.6 billion, making it the second-largest telecom equipment provider in the world.

These businesses are super un-sexy but critical to our everyday lives, as they provide the infrastructure that powers internet and mobile connectivity. Telecom operators like Verizon and AT&T depend on companies like Nokia and industry-leading Ericsson to help them handle the ever-increasing volume of data necessary to fuel our constantly connected lives.

After all, someone has to make sure that our Netflix shows stream smoothly, right?

Yahoo to buy Foursquare?

The rumors are swirling again. Will Yahoo finally buy Foursquare after years of speculation?

Marissa Mayer has acquired plenty of companies over the last couple of years, and this one would certainly make sense. Acquiring Foursquare would boost Yahoo’s search efforts by adding a robust amount of location search data to the company’s primary set of local listings. And of course it would augment Yahoo’s portfolio of mobile apps, which is one of Mayer’s key strategic initiatives.

Let’s wait and see if this will actually ever happen.
