Love them or hate them, drones are increasing in popularity and there have already been incidents of propellers cutting and even blinding people. As a result, we are only just learning the true damage the propellers can cause. To study how the blades can tear through flesh, researchers have attached a drone to a catapult and fired it at a slab of pork in a bizarre slow-motion video. Researchers at a Danish University have rigged a purpose-built catapult to launch a hobby drone into the pork at high speed, recording the impact with a high-speed camera capturing 3,000 frames per second (pictured). Researchers at Aalborg University's Drone Research Lab rigged a purpose-built catapult to launch a hobby drone into the meat at high speed.

Cian Westmoreland was 18 years old when he enlisted in the US Air Force. Now 28, the former serviceman served with the 606 Air Control Squadron in Germany and the 73rd Expeditionary Air Control Squadron in Kandahar, Afghanistan, as an Air Force Technician. He built the communications infrastructure for the US military's drone programme in Afghanistan, which, according to a 2015 report by The Intercept led to the deaths of hundreds of civilians. In 2010, after four years in the military, he left the Air Force and joined other whistle-blowers speaking out about US drone policy. The group of technicians and operators wrote an open letter to US President Barack Obama.

Now that Facebook can stream live video through virtually any device, you're going to find those live feeds coming from unusual places... including overhead. DJI is promising an update in late April that will let you stream its drones' video through Facebook Live, making it comparatively easy to share those dramatic skyline shots with your friends. The feature will work for any model that plays nicely with the DJI Go mobile app, which largely includes recent Phantom and Inspire drones. While you could stream to YouTube before, this definitely widens the playing field -- there's a better chance that more of your social circle will witness your aerial exploits.

Facebook plans to unveil two projects on Wednesday that promise to improve Internet connectivity for users in cities and urban areas. The two, called Aries and Terragraph, will be detailed at its F8 conference in San Francisco, CEO Mark Zuckerberg said on Tuesday. Together, they represent an extension of Facebook's connectivity efforts that so far have been most closely identified with Aquila, a high-flying drone designed by the company to beam down an Internet signal to remote areas. Getting people online and keeping them connected is key to Facebook's expansion plans. After all, it won't be able to persuade new users to come to its services if the Internet connection isn't reliable.

Facebook's F8 developer conference has only been going for a few hours, and already there's been some huge announcements. Gone are the days when F8 was just for announcing newsfeed redesigns - in the opening keynote speeches, we've heard about a brand new Messenger chatbot platform, a solar-powered WiFi plane, and all kinds of live video innovations. Here's some of the main things we learned at the F8 opening event. Zuckerberg straight away took a thinly-veiled swipe at the Republican presidential candidate while talking about Facebook's plan to'connect the world'. Speaking to the assembled crowd of developers, Zuckerberg said: "As I look around the world, I'm starting to see people and nations turning inwards, against the idea of a connected world and global community."

The bots are, for sure, coming to Facebook. After nearly a year of rumors circulating about Facebook creating a bot store and several other apps releasing such a system, the company has announced its own system for users to communicate with businesses without another human on the other line. "I don't know anyone who likes calling businesses," said CEO Mark Zuckerberg. "We think there's got to be a better way to do this. Facebook released Messenger Platform Tuesday, Zuckerberg announced at the company's annual F8 developers conference. Launch partners include CNN and 1-800-Flowers. The system now lets a Messenger user get news from CNN and order flowers, for example, by chatting with a bot. "To order from 1-800-Flowers, you never have to call 1-800-Flowers again," Zuckerberg said, inspiring laughs from the audience. Additionally, Facebook released an application programming interface for live video, which means app developers can integrate Facebook's live product into their own apps or websites. For example, drone manufacturers can integrate Facebook Live into their devices to live-stream video from a drone. Not every developer at F8 or beyond the conference may choose to build a company on Facebook's chatbots, but it can be a quicker way to grow and establish a business than trying to market one's own app. "You're going to see a lot of really successful small businesses that are chatbot-based.

Facebook co-founder Mark Zuckerberg shows how developers can bring Facebook Live to other products, like drones at F8 conference. SAN FRANCISCO - Facebook's Live initiative is now open to outside developers, a move that will bring outside products to your Facebook news feed with live mobile broadcasting. Appearing at the F8 conference for developers, Facebook co-founder Zuckerberg said live mobile streaming within the Facebook app has worked out very successfully for TV stars, in particular. "Many of them have bigger audiences on Facebook than they do on their TV shows," he said. By opening to developers, companies like Buzzfeed, Tastemade and drone maker DJI can live stream directly to Facebook news feeds.

Facebook's f8 developers conference marks the rise of the chatbots. The social networking giant unveiled its Messenger Platform on Tuesday, which will leverage "chatbots" that interact with users and perform several tasks while remaining in the app, including shopping. For a recap of the keynote, scroll down for our live updates. "So we set out to build the perfect 360-degree camera," he says. Facebook unveils the Facebook Surround 360 camera.

Australia has warned the world that artificially intelligent killer robots "may be closer than many of us had imagined" and nations need to work harder to tackle the future threat they may pose. Is the Australian Defence Force the next big customer for unmanned aerial vehicles? At a United Nations meeting on "lethal autonomous weapons systems" in Geneva, Switzerland, the Australian delegation on Monday night called on the world to come up with agreed rules about how to handle the rapid pace in technology in military artificial intelligence. "The development of fully autonomous systems able to conduct military targeting operations which kill and injure combatants or civilians may be closer than many of us had imagined," the delegation's statement said. "It is an appropriate time to consider the risks of such weapons systems and to make sure we understand fully what might constitute misuse as well as legitimate use of emerging technologies."

At a United Nations meeting on "lethal autonomous weapons systems" in Geneva, Switzerland, the Australian delegation on Monday night called on the world to come up with agreed rules about how to handle the rapid pace in technology in military artificial intelligence. The Terminator movies imagined a future where killer robots posed a threat to humanity: some warn that the threat is real. "The development of fully autonomous systems able to conduct military targeting operations which kill and injure combatants or civilians may be closer than many of us had imagined," the delegation's statement said.
