When 20-year-old U.S. Navy hopeful Cameron Massengale lost his arm in a work accident, he wasn't sure he'd ever be able to march as a cadet at The Citadel again. But thanks to a custom prosthetic arm and his refusal to settle, Massengale has not only returned to the group but also became the first amputee to make the university's Summerall Guards, a silent precision drill platoon, in January. Massengale is the first amputee to make the platoon at The Citadel, a military college in Charleston, S.C. It just kind of happens," Massengale told FoxNews.com. Massengale has four prosthetics, including one myoelectric prosthetic with a bionic hand and a drill prosthetic has a two-fingered hook so he can perform quick, open-and-close movements like picking up or setting down his rifle. Creating his drill arm took some trial and error, said Jon Nottingham, a certified prosthetist orthotist and area clinic manager at the Hanger Clinic in Greenville, South Carolina.

It's day one at the Singularity University: the opening address has just been delivered by a hologram. Craig Venter, who was one of the first scientists to sequence the human genome and created the first synthetic life form, is up next. And later, we will see two people, paralysed from the waist down, use robotic exoskeletons to rise up and walk. But first, the co-founder of the Singularity University, Peter Diamandis, gives us our instructions for the day. Your task, he says, is to pick one of the "grand challenges of humanity" – the lack of clean drinking water, say. And then come up with an idea that "can positively impact the lives of a billion people". Some of us haven't even had coffee yet. There's about 50 of us present and the room has been divided up into tables, one for education, another for poverty, another for water, and I'm not sure where I should sit. Diane Murphy, the university's PR executive, hesitates for a moment and then directs me over to the table marked "food". "Tell you what," she says.

Knowing a cyberattack's going to occur before it actually happens is very useful--but it's tricky to achieve in practice. Now MIT's built an artificial intelligence system that can predict attacks 85 percent of the time. Cyberattack spotters work in two main ways. Some are AIs that simply look out for anomalies in internet traffic. They work, but often throw up false positives--warnings about a threat when actually nothing's wrong. Other software systems are built on rules developed by humans, but it's hard to create systems like that which catches every attack.

Existing threat-detection systems broadly fall into two categories: a software bot that can detect patterns and human analysis. AI2's gimmick is that it mashes together a handful of different machine learning tools and asks its flesh-and-blood counterparts for help. When it thinks it's found a pattern amongst the noise of data, it offers it up to a person for a second opinion. After a short period of time, AI2 will learn from its errors and what the human experts are telling it. As Arnaldo says, "it continuously generates new models that it can refine in as little as two hours."

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

Computing jobs are growing at twice the national rate of other types of employment. By 2020, the Bureau of Labor Statistics says, the US will have 1 million more computer science-related jobs than graduates qualified to fill them. In December, President Obama announced the Computer Science for All Initiative, pledging 4 billion in funding for computer science education in the nation's schools. Yet all kinds of dysfunction keeps the country from closing the deficit in computer science talent, according to a survey by Google and Gallup. Yes, school budgets are a problem, and teachers have a limited time to devote to additional classes.

Finding evidence that someone compromised your cyber defenses is a grind. Sifting through all of the data to find abnormalities takes a lot of time and effort, and analysts can only work so many hours a day. But an AI never gets tired, and can work with humans to deliver far better results. A system called AI2, developed at MIT's Computer Science and Artificial Intelligence Laboratory, reviews data from tens of millions of log lines each day and pinpoints anything suspicious. A human takes it from there, checking for signs of a breach.

Some judges might think you're allowed to shoot down drones that encroach on your turf, but don't tell that to the Federal Aviation Administration. In response to Forbes' questions, the agency says that shooting down a drone is a federal crime. You're still damaging an aircraft, according to the FAA -- it's just that this one doesn't have a pilot onboard. You could face up to 20 years in prison as a result, which is bound to make you think twice about blasting that drone peeping at your backyard.

The Metropolitan Police have opened an investigation into reports that a drone struck a commercial passenger plane as it approached London's Heathrow airport. On Sunday, the pilot of a British Airways flight from Geneva, Switzerland, reported that a drone had struck the front of the Airbus A320, which was carrying 132 passengers and five crew members. British Airways inspected the plane but found it was undamaged and deemed safe for its next flight. No one has been arrested following the incident and it is not known who owned the drone or why it was being flown in an area with so many passenger planes. In the U.K., airports and their surrounding areas are controlled airspace where the flying of drones is prohibited.
