Marissa Mayer

Yahoo! is buying Tumblr for $1.1 billion! On Sunday, Yahoo!'s board approved the deal for the microblogging network popular with animated GIF lovers and celebrities like Beyoncé. There are more than 108 million blogs on the social network, and the acquisition is yet another bold move by Yahoo! CEO Marissa Mayer, who is attempting to revitalize the Internet giant and appeal to a younger demographic. The deal, which is even bigger than Facebook's $1 billion acquisition of Instagram, is expected to be finalized as soon as Monday. Tumblr's 26-year-old founder David Karp dropped out of high school at age 15 to work as a programmer.

Time magazine unveiled its annual list of the most influential people in the world, and while it's full of household names from political figures like President Barack Obama to entertainment mogul Jay-Z and celebrated writer-director-actress Lena Dunham, female leaders in science and technology also made the cut among the "artists and leaders . . . pioneers, titans and icons."

Familiar tech faces Marissa Mayer, Yahoo CEO, and Sheryl Sandberg, Facebook COO, are listed as pioneers and titans, respectively. Both are powerful leaders in Silicon Valley, with the Yahoo chief leading the company back to its former tech glory, and with her new book, Lean In, Sheryl is reexamining gender politics in the workplace as they relate to keeping women from balancing the career success and family home life.

The C-suite isn't the only representation of women in the sciences, though; read on to learn about women revolutionizing education, helping to eradicate AIDS and breast cancer, and connecting remote locations to the power of the web.

Not everyone is unhappy about the new work-from-home ban at Yahoo! that will take effect in June. In fact, some employees have spoken up in support of it on the question-and-answer website Quora.

One anonymous user's answer, which received 582 upvotes and counting, states an overhaul is needed in the company and this new work-from-office-only policy is just part of it. Though many will compare Yahoo! to tech companies like Google that have more flexible working arrangements, anonymous retorts, "My question would be have you seen their P&L? They make boatloads of money. We are fighting to stay relevant. So getting your ass into the office and working on projects is not too much to ask."

The work-from-home policy isn't as strict as it's being reported, according to another anonymous user, and the firm is still reasonable when it comes to emergencies.

If you're one of the hundreds of disgruntled Yahoo! workers that now have to show up at the office full-time after the company's new edict to cease work-from-home arrangements come June, you might be looking for a new job. Here are some firms that would give you the option of telecommuting:

Less than a year after former Google employee, Marissa Mayer, took the reins of Yahoo as CEO, the company unveiled a shiny, new homepage today. With an infinite scroll newsfeed and polished look that is much less cluttered than the old view, Yahoo hopes the makeover will have its landing page once again become your home site.

So what's different other than the surface change?

• Facebook sign-in — If you have a Yahoo account go ahead and sign in with that, but as of today, you can also sign in to Yahoo with a Facebook account. The site will also pull in Facebook friends' birthdays, so there's no way of forgetting the occasion, and show you stories recommended by those same pals.
• Flickr sidebar — Peep the latest Flickr uploads in the lower right hand corner of the page.
• Customizable newsfeed — Instead seeing a round down of the day's biggest news, you can now select which topics you'd like to see in the feed. More sports coverage? Done! Only care about business news? You got it.

For Android and iOS users, Yahoo also gave its mobile site a more touch-friendly experience, which you can take a look at after the break.
