In a few years, the exterior of the International Space Station could be crawling with geckos. The robotic geckos could follow from an experiment NASA launched to the International Space Station on Tuesday aboard an uncrewed Cygnus spacecraft. The Gecko Gripper devices use tiny artificial hairs that replicate the ones geckos use to climb walls. They are designed to help astronauts to keep track of objects in zero gravity, and enable robots to crawl around a spacecraft to inspect and repair it. The bots have already been tested on parabolic aircraft flights, where they grabbed and manipulated 10-kilogram and 100-kg objects during 20-second periods of microgravity.

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

Drones are experiencing something of an arms race for aerial domination. As fast as the technology develops to make the unmanned vehicles better in the air, new ways are being developed to take them down. Video footage has emerged of a soldier in the US using a'cyber rifle' to take down a drone, causing it to lose power instantly in flight before falling out of the air. Video footage has emerged of a US soldier using a'cyber rifle' to take down a drone, causing it to lose power instantly in flight and fall out of the air (still pictured). The cyber-rifle is built by the Army Cyber Institute at West Point in the US, and was tested in front of the US Secretary for Defense, Ash Carter.

A self-driving car is, in the words of the roboticist Missy Cummings, "one, big data-gathering machine." Which, on one hand, is great: For driverless cars to work, they have to slurp up huge streams of sensory data about the world around them. But these vehicles will also collect reams of personal information about their passengers--just the way Uber and Google Maps have detailed information about where you've gone, and can predict where you're going. This isn't necessarily bad--there are all kinds of neat services that might rely on personalized data--but it does raise the question of how, if at all, data collection ought to be regulated. This topic came up last week at a Congressional hearing on driverless cars, and the companies potentially doing the data-collecting were, and this is putting it gently, evasive.

U.S. President Barack Obama discussing his Computer Science for All plan to give students across the country the chance to learn computer science in school. In late January, U.S. President Barack Obama asked Congress to approve 4.1 billion in spending in the coming fiscal year to support the Computer Science for All initiative, aimed at providing computer science education in U.S. public schools. Obama pointed out computer science is no longer "an optional skill" in the modern economy," yet "only about a quarter of our K–12 (kindergarten through 12th grade) schools offer computer science. Twenty-two states don't even allow it to count toward a diploma." While many organizations have contributed to the national effort to see real computer science exist and count toward graduation requirements in U.S. public schools, former ACM CEO John R. White said, "ACM has been there from the beginning." Indeed, White contends Obama's Computer Science for All initiative "in a way represents the ...

More than 20% of U.S. adults live with some form of disability, according to a September 2015 report released by the U.S. Centers for Disease Control and Prevention. The latest generation of smartphones, tablets, and personal computers are equipped with accessibility features that make using these devices easier, or at least, less onerous, for those who have sight, speech, or hearing impairments. These enhancements include functions such as screen-reading technology (which reads aloud text when the user passes a finger over it); screen-flashing notification when a call or message comes in for the hearing impaired; and voice controls of basic functions for those who are unable to physically manipulate the phone or computing device's controls. Other technologies that can help the disabled have or are coming to market, and not all of them are focused simply on providing access to computers or smartphones. Irrespective of the accessibility provided, most market participants agree more needs to be done to help those with disabilities to fully experience our increasingly digital world.

Secretary of Defense Ash Carter is just out of frame on the right side of the screen. As soon as it was airborne, the drone flying inside West Point crashed to the ground at the feet of Secretary of Defense Ash Carter. The soldier responsible for the drone's demise gently lowered the weapon, no smoke wafting from its barrel, not even a sound made with the shot. Built by the Army Cyber Institute at West Point, the rifle was demonstrated last fall at the Association of the United States Army exposition in Washington, DC. Unlike pretty much every other variety of gun, this rifle doesn't shoot any projectiles.

It is widely regarded as one of the greatest human achievements ever made, but putting a man on the moon was no cheap undertaking. The Apollo missions to send just 12 men onto the dusty lunar surface cost 25 billion ( 17 billion) – estimated to be worth around 170 billion ( 120 billion) in modern monetary value. But it appears we may be able to send humans back to our rocky satellite and set up a permanent base where they could live for just a fraction of the cost. The cost of building a base on the moon could be a fraction of what has been previously expected. Scientists say it may be possible to build a permanent base (illustrated) housing 10 people within the next five to seven years for around 10 billion.
