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.

GPS falls from the sky and costs nothing to use, but it may not reach a car roving the canyons of Manhattan or a forklift moving boxes in a warehouse. For uninterrupted autonomous driving, you need some backup. Sure, you can festoon your vehicles with a vast array of overlapping sensors, but even that won't always give you a clear sense of where you are. So, when the GPS satellites can't pinpoint you, why not resort to land-based beacons? That's the solution proposed by 5D Robotics, a Carlsbad, Calif.

A Swiss data analytics and cybersecurity company is beefing up its Boston-area presence after grabbing 40 million in venture capital, led by Highland Europe. Nexthink established a U.S. presence three weeks ago with the opening of a sales office in Cambridge, MA. The company employs about 10 people there to start, but it plans to grow to 120 local employees over the next 18 months, a spokeswoman says. Nexthink helps IT departments analyze and monitor their businesses' applications, devices, and other network activity in real time. The goal is to sniff out cyber attacks and minimize software disruptions for end users.

In most ancient cultures, literacy was rare, reserved for specialized scribes or religious officials. But new research shows that in the ancient kingdom of Judah, literacy may have been widespread, a fact that may reshape the timeline of when and where the Hebrew Bible or the Old Testament was written. In a study recently published in Proceedings of the National Academy of Sciences (PNAS), researchers looked at 16 ink inscriptions from a Judean fort in Arad--a remote border post in ancient times--written around 600 BCE. Using computerized imaging and machine learning tools, Tel Aviv University researchers were able to determine that the messages were written by at least six different individuals. According to a press release, the incriptions were primarily about mundane topics, like troop movements and food expenses. The nature and tone of the inscriptions, the researchers say, indicates the ability to read and write all through the chain of command, from the commander of the small garrison to the deputy quartermaster of the fort.

SEOUL/WASHINGTON – Ahead of a rare congress of the ruling party next month, secretive North Korea is revealing details of its weapons development program for the first time, showcasing its push to develop long-range nuclear missiles despite international sanctions. Until recently, information on the North's weapons program was hard to come by, with foreign governments and experts relying on satellite imagery, tiny samples of atomic particles collected after nuclear tests and mangled parts recovered from long-range launches. In just over a month, the North has published articles with detailed color photos on a range of tests and other activities that point to fast-paced efforts to build a nuclear-armed intercontinental ballistic missile (ICBM). The reason for the revelations, many analysts say, is that Pyongyang believes that convincing the world, and its own people, of its nuclear prowess is as important as the prowess itself. Nevertheless, the isolated North's true capabilities and intentions remain unknown.

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.

Google has received tons of gushy press for its bubble-shaped self-driving car, though it's still years from the showroom floor. But for years John Deere has been selling tractors that practically drive themselves for use on farms in America's heartland, where there are few pesky pedestrians or federal rules to get in the way. For a glimpse at the future, meet Jason Poole, a 34-year-old crop consultant from Kansas. After a long day of meetings earlier this month and driving five hours across the state to watch his little girl's softball game, he was still able to run his John Deere tractor until 2 a.m. The land is hilly on Poole's family farm, so he drives the first curved row manually to teach the layout to his tractor's guidance system and handles the turns himself.
