The United States military killed a senior Al Qaeda leader Tuesday in an airstrike in Afghanistan's southern Zabul Province, the local website Tolo News reported, citing a statement from Afghan special forces. The Al Qaeda commander killed in the airstrike was identified by Afghanistan's Ministry of Defense as Mullah Mohammad Ali. The U.S. military confirmed a strike took place in the same location yesterday, but would not say whether a senior Al Qaeda leader was killed. "We can confirm that U.S. Forces conducted a counter-terrorism strike in the Shah Joyi district, Zabul province, May 17. For operational security reasons, we do not discuss the details of counter-terrorism operations," said the statement from Operation Resolute Support, the name for the U.S.-led mission in Afghanistan.

As useful as robot arms are, they tend to be heavy, bulky things that need a bunch of support and structure to get them to work properly. If you need precision and speed, this may be unavoidable, but if all you're looking for is long reach, a high-strength to weight ratio, and very low cost (which, admittedly, are a lot of things to be looking for), another option was presented at ICRA today by researchers from the University of Pennsylvania: an arm made out of a strip of plastic that zips together with itself, creating an extendable cylinder that can be paired with winches and cables and used for manipulation. This concept is similar in principle to some commercially available systems like the Zippermast and Spiralift, but both of those designs are heavier and significantly more complicated. The spiral zipper uses a single band that's made of very lightweight plastic, with a relatively simple meshing mechanism that meshes the teeth on the bottom edge of one wrap with the teeth on the top of the wrap below to create a cylinder that has a very high strength to weight ratio, with exceptionally good compressive performance. And changing the length of the arm is as simple as zipping or unzipping the band: it's completely reversible, and you can stow the arm almost entirely in a very small volume consisting of the plastic band spooled around the zipping mechanism.

Facebook's Moments app uses facial recognition technology to group photos based on the friends who are in them. Amid privacy concerns in Europe and Canada, the versions launched in those regions excluded the facial recognition feature.

When someone tags you in a photo on Facebook, it's often a nice reminder of a shared memory.

Nasa has announced that it has found evidence of flowing water on Mars. Scientists have long speculated that Recurring Slope Lineae -- or dark patches -- on Mars were made up of briny water but the new findings prove that those patches are caused by liquid water, which it has established by finding hydrated salts. Several hundred camped outside the London store in Covent Garden. The 6s will have new features like a vastly improved camera and a pressure-sensitive "3D Touch" display

Queen Elizabeth II donned an ermine-trimmed robe and diamond-studded crown Wednesday to announce government promises to put Britain at the cutting edge of technology and social progress in the 21st century. Plans for prison reform, a sugar tax and commercial spaceports were among 21 bills announced in the Queen's Speech, an annual tradition that mixes lavish pomp and modern politics. Prime Minister David Cameron called it a "progressive, one-nation" program, but some measures are sure to meet resistance -- and next month's referendum on European Union membership is casting a shadow over the government's plans. The annual State Opening of Parliament is steeped in centuries-old symbolism of the power struggle between Parliament and the British monarchy. In a display of regal wealth and finery, the queen traveled from Buckingham Palace in the horse-drawn Diamond Jubilee State Coach, and delivered the speech -- written for her by the government -- wearing the Imperial State Crown, studded with 3,000 diamonds.

My name is Jonathan Armoza and I am a data science intern at Neustar and a PhD candidate in English Literature at New York University. My work focuses on the development of computational text mining and visualization methods in the emerging field of digital humanities. The era of big data has created the need to develop techniques and mechanisms to not only handle large datasets, but to understand them as well. Much of this influx of information is about people, places, and things. Although some of that data is anonymized, there are a number of reasons we might want to understand how to associate those real world "entities" with their data points.

Before our species set foot on the moon, we orbited it first. The same will probably be true for Mars, and on Wednesday, Lockheed Martin plans to unveil its vision for a spacecraft that could make it happen. The "Mars Base Camp," as the company is calling it, would set up a laboratory, staffed by 6 astronauts, in Mars orbit in 2028. Up to now, NASA has outlined the first few steps to Mars. It's building a heavy-lift rocket, the Space Launch System (SLS), and working with Lockheed to build the Orion crew capsule.

The US Navy is set to use a radical new drone that can be launched from a submarine. The Blackwing drone is stored in a three inch tube, and uses existing systems submarines use for acoustic countermeasures. Once airborne, the shell falls apart and the drone unfurls its wings. The Blackwing drones are launched from a three-inch canister aboard submarines or unmanned underwater vehicles. The miniature UAVs are launched through the boats' existing systems it uses for acoustic countermeasures and have a flight endurance of less than an hour'AeroVironment's new Blackwing unmanned aircraft system is a valuable new capability that resulted from our team's close collaboration with, and responsiveness to, the U.S. Navy's undersea warfare community and the Special Operations community,' said Kirk Flittie, AeroVironment vice president and general manager of its Unmanned Aircraft Systems business segment.

Britain's first astronaut has said the UK risks becoming a "backward nation" if the government does not pay to send more people into space. Helen Sharman believes the country would lose many of the benefits of Tim Peake's mission if a commitment to more flights is not made very soon. Ms Sharman said that this was the UK's "last chance" to be involved "in the future of the human race". She spoke to BBC News on the eve of the 25th anniversary of her spaceflight. The government has effectively paid for one spaceflight, Tim Peake's, according to Ms Sharman.
