WASHINGTON – Congress passed an aviation bill Wednesday that attempts to close gaps in airport security and shorten screening lines, but leaves thornier issues unresolved. The bill also extends the Federal Aviation Administration's programs for 14 months at current funding levels. It was approved in the Senate by a vote of 89 to 4. The House had passed the measure earlier in the week and it now goes to President Barack Obama, who must sign the bill by Friday when the FAA's current operating authority expires to avoid a partial agency shutdown. Responding to attacks by violent extremists associated with the Islamic State group on airports in Brussels and Istanbul, the bill includes an array of provisions aimed at protecting "soft targets" outside security perimeters. Other provisions designed to address potential "insider threats" would toughen vetting of airport workers and other employees with access to secure areas, expand random employee inspections and require reviews of perimeter security.

Autonomous, a company specializing in robotics and artificial intelligence products, recently began an Indiegogo campaign for its Drone Racing Kit. The modest 10,000 goal was met within an hour of launching, and the device is still gaining momentum. The Drone Racing Kit features two drones, two controllers, flags, cones, and a backpack, in addition to two VR headsets. The headset itself is similar to Samsung's Gear VR and Google Cardboard in that it slips over a mobile device (phone or tablet) and uses lenses to project the images three-dimensionally. The drones sport a camera that brings the user to the pilot seat with the mobile HMD, providing a first-person view of the remote-controlled device as it soars around a track of your own design.

The sight of flying umbrellas, changing altitude with a fluttering rhythm, looks more like an animated Disney scene than graduate work by a student engineer. "I wanted to push the envelope of coordinating drones in the sky," says the project's creator Alan Kwan, a student in MIT's "ACT" (Art, Culture and Technology) program. He wanted his drones to act almost alive, "not like things to be controlled by an algorithm," he says, "but flying creatures that take on a synchronous life." A Hong Kong native, Kwan, 25, has explored scientific art before. He won an award for his Beating Clock project, a reanimated pig heart that keeps time.

Four small rotors to take off and land, one big engine to fly through the sky. Could crowds design the drone of the future? European aviation giant Airbus and Arizona-based open-source manufacturing company Local Motors held a contest for designers across the world to create a new drone concept. This morning, they announced all the winners. Check out the Zelator, by Alexey Medvedev of Omsk, Russia, which won first place in the Airbus Main Prize.

In this Dec. 17, 2014 file photo, a Pakistan army soldier inspects the Army Public School that was attacked a day before by Taliban gunmen, in Peshawar, Pakistan. The Pakistani army said Wednesday, July 13, 2016 that the mastermind of the 2014 attack on an army-run school has been killed in a U.S. drone strike. A Pakistani military spokesman says that a U.S. Army general confirmed the death of Taliban leader Khalifa Umar Mansoor in a phone call to Pakistan's army chief.

Years ago, I was working on a project that needed to be adaptive. Essentially, the software needed to learn and get better at a frequently repeated task over time. I'd read about neural networks and some early success people had achieved with them, so I decided to try it out myself. That marked the beginning of a life-long fascination with AI. AI is a really big deal.

The depths of the ocean can be a dangerous place, even for a drone. Incredible footage has captured the moment a Great white shark mistakes the machine for food and attacks it with amazing speed and precision. It is believed the video was filmed off the coast of Australia where Great whites are commonly spotted in southern waters from Exmouth in Western Australia to Southern Queensland. The video shows the metal drone sitting deep in the ocean, when almost out of nowhere the underwater beast appears. Within seconds the Great white wraps it teeth around drone and viciously tugs at it before realising the hunk of metal is not a tasty meal.

Drone technology is developing so quickly--and morphing into commercial uses never before contemplated--that aviation regulators are having trouble keeping pace. Air-safety authorities on both sides of the Atlantic have acknowledged that traditional rule making is too slow and rigid to cope with the rapidly expanding applications of the flying machines, from bridge inspections to land surveys to news photography. And the pressure to spell out exactly what's allowed and what isn't is growing as the industry booms. Millions of hobbyists already operate drones, and over the next few years businesses are projected to begin flying millions more in the U.S. alone. Now regulators are scrambling to draft new, more-nimble rules and procedures.

"Really, we're building collision avoidance for industrial drones," said Alexander Harmsen, CEO and co-founder of Iris Automation. "We see this huge need for industrial drones for mining exploration, pipeline inspection, agricultural surveying, forestry, or even package delivery." Without a way to avoid mid-air collisions, drones risk crashing into a Cessna, a flock of geese or a 747. Worst case scenario: a drone gets sucked into a jet engine causing catastrophic engine failure as high-velocity bits of metal penetrate fuel tanks, hydraulic lines and the cabin. Iris Automation's solution is an AI computer that blends real-time images and 3D maps to track incoming objects.
