Pentru prima dată, AI domină ce este mai bun al umanității într-un sport din lumea reală PDF Imprimare

                       Now they're beating us in real-world sports: an AI has dominated world-champion drone racers head-to-head

    High-speed drone racing has just had a shocking "Deep Blue" moment, as an autonomous AI designed by University of Zurich researchers repeatedly forced three world champion-level pilots to eat its dust, showing uncanny precision in dynamic flight.




If you've ever watched a high-level drone race from the FPV perspective, you'll know how much skill, speed, precision and dynamic control it takes. Like watching Formula One from the driver's perspective, or on-board footage from the Isle of Man TT, it's hard to imagine how a human brain can make calculations that quickly and respond to changing situations in real time. It's incredibly impressive.

When Deep Blue stamped silicon's dominance on the world of chess, and AlphaGo established AI's dominance in the game of Go, these were strategic situations, in which a computer's ability to analyze millions of past games and millions of potential moves and strategies gave them the edge.

But now, for the first time, AI has beaten some of the world's best in a real-world, physical sport. An AI system called Swift, developed by researchers from the University of Zurich and Intel, quickly learned a tight, technical 3D racetrack, and proceeded to dominate two human world champions and a three-time Swiss national champion in head-to-head racing, also setting the fastest race time.

Imaginile cu neutroni dezvăluie zincul ca fiind vinovat în prăbușirea radiotelescopului Arecibo PDF Imprimare

                          The instrument platform crashing into the radio telescope antenna

     Almost three years after the event, neutron scans by the Oak Ridge National Laboratory have uncovered the cause of the platform collapse that resulted in the destruction of the 1,000-ft (300-m) Arecibo Observatory radio telescope.
     Constructed in 1963, The Arecibo radio telescope was constructed in a natural sinkhole, with a 1.8-million-lb (816,000-kg) steel platform suspended at the focus point 500 ft (150 m) above the mesh dish. For over 50 years it performed cutting-edge astronomical research, beamed one of the first messages into space in an attempt to contact alien civilizations, and was the setting for the climax for the 1995 Bond thriller GoldenEye.

        SpaceX Crew-7 de la NASA se lansează pe Stația Spațială Internațională

               NASA's SpaceX Crew-7 launches to International Space Station.

     An international crew of four representing four countries is in orbit following a successful launch to the International Space Station at 3:27 a.m. EDT Saturday, Aug. 26, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The agency’s SpaceX Crew-7 mission is the seventh commercial crew rotation mission for NASA.

    A SpaceX Falcon 9 rocket launched the Dragon spacecraft into orbit carrying NASA astronaut Jasmin Moghbeli, ESA (European Space Agency) astronaut Andreas Mogensen, JAXA (Japan Aerospace Exploration Agency) astronaut Satoshi Furukawa, and Roscosmos cosmonaut Konstantin Borisov, for a science expedition aboard the orbital laboratory.

Cojile reziduale de aloe vera pot fi o sursă de insecticid ecologic PDF Imprimare

                                Some of the dried aloe vera peels utilized in the study

     Although the gel of the aloe vera plant is commonly used to treat sunburn, moisturize skin and boost gut health (among other applications), its peels are typically discarded. New research now suggests that those peels could also be used, to make non-toxic insecticide for use by farmers.

     The study is being led by Asst. Prof. Debasish Bandyopadhyay, of the University of Texas - Rio Grande Valley.

Racheta anti-ICBM a lui Lockheed Martin depășește o etapă majoră de dezvoltare PDF Imprimare

                       Artist's concept of the Lockheed Martin NGI missile

   America's Next Generation Interceptor (NGI) for countering rogue state ICBM attacks has passed a major milestone. Lockheed Martin has announced that the US Missile Defense Agency (MDA) has passed all design elements of the company's NGI missile project.

   Despite the dramatic reduction of the world's nuclear arsenals and launch platforms after the end of the Cold War, there are still an worryingly large number of warheads still poised for launch across the world. With hundreds of missiles aimed at the United States at any moment, the new 21 planned NGIs as part of the nation's Ground Missile Defense (GMD) system seems comically small compared to the threat.
