While the “Like” button on Facebook has traditionally been a quick and fun way to respond to a post, the truth is that it’s not always appropriate. “Liking” certain posts — say, the news of a pet’s death or a post about global warming — just feels wrong. Thankfully, starting today, that’s about to change. The social network has just announced a brand new feature called Reactions (which we’ve already heard about a few times ), which is essentially an extension of the Like button. Now, in addition to the thumbs-up Like we’re all familiar with, there’s Love, Haha, Wow, Sad and Angry. Love is signified by a heart symbol while the rest are animated emoji. To see them, simply press and hold on the Reactions button — it’s where the thumbs-up Like button is currently — select which one you want, and release. If the post has a slew of different reactions to it, you’ll see a summary of the three most frequent reaction icons. On the other end, the person receiving them will get notifications saying someone “reacted” to the post. Introducing Reactions from Facebook on Vimeo . “People come to Facebook and share all kinds of things, ” says Sammi Krug, the product manager behind Reactions. “And we kept hearing feedback from people that there wasn’t an easy way to express empathy for these different kinds of posts.” Zuckerberg in particular took the user feedback to heart and pulled a bunch of people together to start work on a solution about a year or so ago. From there, the team did a ton of research — from conducting surveys to analysis of the most popular stickers — to figure out just what reactions to add. When they whittled it down to about six, Facebook then began testing it — you can see we saw a sneak peek of Reactions as early as last October — in about seven different countries. “One of the things we really wanted to be careful of, is will this translate well” says Krug. “We wanted these reactions to be globally understood.” That’s one of the reasons Reactions is launching with just five additional icons instead of the original six that we saw in October. That’s because the “Yay” reaction just didn’t test well globally and was a little too vague in some markets. The rest, however, proved to be popular enough, with Love being the most popular out of all the new Reactions (The Like button, however, still reigned supreme). So does that mean we’re stuck with the six or so Reactions we have now? Not at all. “Once this actually rolls out, we’ll learn more about how people use the feature, ” says Krug. “We’ll continue to iterate it over time, based on user feedback.” Reactions will roll out globally starting today on iOS , Android , the desktop as well as the mobile browser. You’ll start to see the change occur over the next couple of days, though bear in mind that you do need to be on the latest version of the Facebook app to get the feature. Still, we had to ask, why isn’t there a “dislike” button? “It would have been too binary, ” says Krug. “This way, though, you’ll have more ways to express yourself. That’s the goal.” Source: Facebook

Facebook officially expands beyond the Like with Reactions
A scientific breakthrough with the “wonder material” graphene has opened up the possibility of indoor solar cells that capture energy from indirect sunlight, as well as ambient energy from household devices. Researchers from the University of Surrey in the U.K. studied the eyes of moths to create sheets of graphene that they claim is the most light-absorbent material ever created. “We realized that the moth’s eye works in a particular way that traps electromagnetic waves very efficiently, ” Professor Ravi Silva, head of the Advanced Technology Institute at the University of Surrey, tells Newsweek. “As a result of our studies, we’ve been able to mimic the surface of a moth’s eye and create an amazingly thin, efficient, light-absorbent material made of graphene.” Read more of this story at Slashdot.
