Sweden's Twitter Account Will No Longer Be Run By Its Citizens

Sweden's official Twitter account is about to feel a lot less personal. As engadget reports, the country will no longer be giving members of the public the power to tweet for it, marking the end of the first social media experiment of its kind.

Instead of hiring a social media professional to manage its Twitter account, Sweden decided to go a different route in 2011: Every week, a different citizen was given access to the @Sweden handle from which they could tweet from their perspective as a regular Swede. The "Curators of Sweden" project was unique when it first launched, but it has since been replicated by countries such as Ireland and the Netherlands.

Sweden's approach to social media has won numerous awards over the years, but it hasn't always been a smooth ride. Some curators in the past have posted unfiltered tweets that you wouldn't want your employer to see—let alone your entire country.

Despite the occasional controversy, the project remained afloat until this year, when Sweden announced it would be handing off the handle to one last curator at the end of September. "Every project has an end, and now—after nearly seven years—it is time for us to move on. We will develop new formats where we can reach more people in more countries than before," representatives of Sweden wrote in a statement.

If you haven't had the pleasure of following the Curators of Sweden until this point, you can browse the project's 200,000 or so archived tweets at curatorsofsweden.com.

This Amateur Rocketeer Builds Functioning, Miniature Replicas of SpaceX Rockets

Amateur rocketry is a hobby that predates NASA. Hobbyists have successfully made it to space using rockets built without the massive budgets and resources available to larger organizations. And some of these rockets do more than reach incredible heights: As Motherboard reports, Joe Barnard, a 25-year-old rocketeer from Nashville, Tennessee, is working on making model rockets capable of propulsive landings, the same trick that makes some SpaceX rockets reusable.

Most rocket boosters that propel loads past the Earth's atmosphere are designed to go only one way. In 2015, Elon Musk's space exploration company SpaceX made history when it successfully maneuvered the boosters used to launch its Falcon 9 rocket back onto the landing pad. SpaceX says its latest version of the rocket can be re-flown up to 100 times, saving the company millions of dollars per launch.

Joe Barnard is bringing this same level of innovation to the amateur rocketry world. He first became interested in aerospace engineering after watching early SpaceX videos, and instead of earning a degree in the field, he taught himself the basics. He's since made rocketry into a career, founding Barnard Propulsion Systems (BPS), a small business that sells supplies to other hobbyists, and working on rockets of his own.

Like the rockets at SpaceX, Barnard's creations use thrust vectoring—the technology that makes it possible to navigate and stabilize a rocket after launch—only on a much smaller scale. He's built miniature models of SpaceX's Falcon 9 rockets, and as is the case at SpaceX, his launches don't always run smoothly.

Barnard is still perfecting propulsive landings in amateur rockets, but for now he says each failure is a learning experience. You can watch the progress of his experiments on his YouTube channel.

This High-Tech Skin Turns Almost Any Object Into a Robot

Instead of trading in their low-tech toys for fancy new gadgets, kids of the future may have the option to turn Teddy into a cyborg. As Gizmodo reports, researchers at Yale University have invented a robot "skin" that can give mobility to just about any inanimate object that can bend.

The researchers describe how this technology, called OmniSkins, works in a paper published in Science Robotics. The material, made from elastic sheets that contain sensors and actuators, can be wrapped around any malleable surface and controlled remotely or with on-board light sensors, essentially turning the item into a makeshift robot. The actuators in OmniSkins manipulate the object, while sensors can gauge exactly how much pressure needs to be applied to perform an action.

The project was largely funded by NASA, and it's easy to see how the tech might be used on one of the agency's missions in the future. On board a spacecraft, every cubic inch of space is precious, and the ability to repurpose something into a robotic arm or rover in a pinch would be invaluable to astronauts.

But the technology has potential applications on Earth as well, and not just to allow stuffed animals to walk on their own. Add a few of the skins to a shirt and it could automatically adjust your posture throughout the day, or you could use them to create a gripper to handle hard-to-reach objects.

You can see OmniSkins in action in the video below.
