Killer whales – also known as orcas – have complex social structures including close'friendships', a new study reveals. Scientists at the University of Exeter used drones to film the animals – one of the world's most powerful predators – in the Pacific Ocean. The team found killer whales (Orcinus orca) spend more time interacting with certain individuals in their pod, and tend to favour those of the same sex and similar age. Results from the new study are based on 651 minutes of video filmed over 10 days. Orcas are the largest member of the dolphin family.

A new study led by the University of Exeter and the Center for Whale Research suggests killer whales may socialise with each other based on age and gender, with younger whales and females more sociable than other groups. The research used drone cameras to study one pod of southern resident killer whales off the US coast of Washington State, in the Pacific Ocean. Around 10 hours of footage was captured over 10 days.

In China, where labor shortages and soaring labor costs are increasingly serious problems, robots are replacing redundant, low value-added and sometimes dangerous human work. Hotels are no exception to this trend. As robot technology continues to improve, the service robots in hotels are attracting attention from venture capitalists and entrepreneurs. Established in 2019, Shanghai Jingwu Intelligent Technology makes robots, primarily for hotels. The startup's management and research and development team was once engaged in the robotics business of a listed company and has 17 years of experience in the field.

As drones become a bigger part of modern warfare, fighting forces are devising creative ways to disable them. The U.S. military recently demonstrated a drone interceptor that fires pink'Silly String'-like streamers at unmanned craft, gumming up their rotors and bringing them crashing down to Earth. The goal is to devise anti-drone technology that doesn't cause as much collateral damage as explosives, according to the Defense Advanced Research Projects Agency (DARPA), and would be used in populated areas. DARPA began developing the interceptor, known as Counter-Unmanned Air System (C-UAS), four years ago as a means to stop small self-guided unmanned aircraft without the kind of major collateral damage caused by gunfire or explosives. In a video posted this week, DARPA demonstrated C-UAS at Eglin Air Force Base outside Valparaiso, Florida.

The US has developed a drone interceptor that fires what appears to be a form of Silly String into their rotors, bringing them down with minimal risk of accidental damage. The interceptor was created by the US Defense Advanced Research Projects Agency (DARPA). It is launched from a vehicle and guided by radar that can automatically identify and track small drones. Once the interceptor has a target drone in sight, it releases string-like streamers – their exact composition is unknown – to disable it. The system can also launch multiple interceptors to deal with several incoming drones simultaneously, and the interceptors are reusable. DARPA says it wants to provide drone defences for convoys and other mobile units in heavily populated areas, where normal military weapons would create too much risk of civilian casualties.

Its platform uses computer vision and artificial intelligence technologies, along with mobile phone cameras and small drones, to develop what it calls …

AI drone may have'hunted down' and killed soldiers in Libya without human input By Charles Q. Choi - Live Science Contributor - June 3, 2021 KARGU a Rotary Wing Attack Drone Loitering Munition System A UN report suggests that at least one autonomous drone operated by artificial intelligence (AI) may have killed people for the first time last year in Libya, without any humans consulted prior to the attack, according to a U.N. report. According to a March report from the U.N. Panel of Experts on Libya, lethal autonomous aircraft may have "hunted down and remotely engaged" soldiers and convoys fighting for Libyan general Khalifa Haftar. It's not clear who exactly deployed these killer robots, though remnants of one such machine found in Libya came from the Kargu-2 drone, which is made by Turkish military contractor STM. Landmines are essentially simple autonomous weapons -- you step on them and they blow up," Zachary Kallenborn, a research affiliate with the National Consortium for the ...

The mathematical engineer and robotics PhD student from the Swiss Federal Institute of Technology Lausanne, or EPFL, had already built a computer model to simulate the trajectories of five autonomous quadcopters flying through a dense forest without hitting anything. But an errant copter wouldn't survive a tête-à-tête with a physical tree. So Soria built a fake forest the size of a bedroom. Motion-capture cameras lined a rail hanging above the space to track the movement of the quadcopters. And for "trees," Soria settled on a grid of eight green collapsible kids' play tunnels from Ikea, made of a soft fabric.

Analog AI processor company Mythic launched its M1076 Analog Matrix Processor today to provide low-power AI processing. The company uses analog circuits rather than digital to create its processor, making it easier to integrate memory into the processor and operate its device with 10 times less power than a typical system-on-chip or graphics processing unit (GPU). The M1076 AMP can support up to 25 trillion operations per second (TOPS) of AI compute in a 3-watt power envelope. It is targeted at AI at the edge applications, but the company said it can scale from the edge to server applications, addressing multiple vertical markets including smart cities, industrial applications, enterprise applications, and consumer devices. To address a wider range of designs, the M1076 AMP comes in several form factors: a standalone processor, an ultra-compact PCIe M.2 card, and a PCIe card with up to 16 AMPs.
