Almost 700,000 unwitting subjects had their news feeds altered as part of a study to gauge effect on emotion.
By Reed Albergotti, The Wall Street Journal
A social-network furor has erupted over news that Facebook (FB), in 2012, conducted a massive psychological experiment on nearly 700,000 unwitting users.
To determine whether it could alter the emotional state of its users and prompt them to post either more positive or negative content, the site's data scientists enabled an algorithm, for one week, to automatically omit content that contained words associated with either positive or negative emotions from the central news feeds of 689,003 users.
The research, published in the March issue of the Proceedings of the National Academy of Sciences, sparked a different emotion – outrage -- among some people who say Facebook toyed with its users emotions and uses members as guinea pigs.
The Google-owned company will allow third-party devices to communicate with and through its smart appliances, positioning them as hubs of the connected home.
By Parmy Olson, Forbes
Nest Labs is taking the next step in its quest to become a hub for the smart home, by letting other gadgets and services access its learning thermostat and smoke detector for the first time.
With the long-awaited developer program Nest is launching Tuesday, other apps and devices will be able to access what Nest detects through its sensors, including vague readings on temperature and settings that show if a person is away from their home for long periods. These services will even be able to talk to one another via Nest as the hub.
Nest, founded by former Apple (AAPL) executive Tony Fadell, has long been seen as one of the leading companies in the smart home revolution. Google (GOOG) bought the company for $3.2 billion in January, and last week Nest bought video monitoring service DropCam for $555 million to (for better or worse) learn how people behave in their homes -- for instance, by reportedly tracking how doors are open and shut.
The market is saturated. Just about every American who will buy a smartphone has already declared loyalty to either Google or Apple, and people are loath to switch.

It's not because the Fire phone is packed with a range of what can only be called parlor tricks -- that is, 3-D interface gewgaws of limited utility. Nor is it because the most interesting thing about the phone -- a button that lets you buy anything you see in real life on Amazon -- is probably more useful for Amazon than for its customers, and already exists on other phones anyway.
The central problems with the Fire, the factors that will kill its sales as surely as they have held Microsoft's (MSFT) Windows Phone to single digit market share in North America, are the following. (Microsoft owns and publishes MSN Money.)

The wrist device is reportedly scheduled to launch this fall and will be equipped with more than 10 sensors, including ones to track fitness.

Apple (AAPL) is planning multiple versions of its smartwatch, likely to be launched in the fall, people familiar with the matter said, as the company tries to counter wearable devices from rivals such as Google (GOOG) and Samsung (SSNLF).
The new wrist device from Apple will include more than 10 sensors including ones to track health and fitness, these people said. Apple aims to address an overarching criticism of existing smartwatches that they fail to provide functions significantly different from that of a smartphone, said a person familiar with the matter.
Apple showed its interest in health and fitness-tracking last month with a new app called Health, designed to collect all of a user's fitness and health data in one spot. However, Apple didn't introduce its own device to collect that data, fueling speculation that the company would unveil a sensor-laden wearable device at a later date.
Video camera maker GoPro is the latest company to open up the IPO process -- long the domain of insiders and institutional investors -- to customers before going public.
By Cadie Thompson, CNBC
Once exclusively for big institutions and large investors, initial public offerings are starting to be somewhat more democratized.
Some companies planning to go public are opting to include employees, fans and customers in their IPO, giving them access to shares at the same time and same price as Wall Street.
Most recently GoPro, whose IPO is expected this year, said it would be opening up the offering to fans and customers.
The company plans to offer 17.8 million shares at a price of $21 to $24 each, according to an SEC documents filed Wednesday.
"While with most IPOs 'friends and family' are defined as a few select people, with our IPO, you're all our friends and family," CEO Nick Woodman said in announcing the IPO deal for the company, which makes wearable video cameras.
