A roomsize computer equipped with a new type of circuitry, the Perceptron, was introduced to the world in 1958 in a brief news story buried deep in The New York Times. The story cited the U.S. Navy as saying that the Perceptron would lead to machines that "will be able to walk, talk, see, write, reproduce itself and be conscious of its existence." More than six decades later, similar claim

What do you picture in your mind's eye when you hear the word "laser"? A light saber? A cat toy? The sensor at the supermarket reading barcodes as fast as the eye can blink? These are all lasers, but there are so many more in so many sizes and colors with capabilities that have yet to be tapped or even imagined. Assistant Professor of Electrical Engineering and Applied Physics Alireza Mara

NASA said Friday the Europa Clipper Jupiter mission set to launch in October will carry profound messages from humanity as it gathers scientific data to determine if there are life-supporting conditions. The Europa Clipper spacecraft will be headed for Jupiter's moon, Europa. In addition to scientific instruments for experiments and data collection, it will include an engraving o

NASA will accept applications through April 2 for future Artemis astronauts who could go to the moon and beyond. The opening of the application period concurred with 10 new astronaut graduates completing an initial two years of training. The space agency said that to apply to become an astronaut, applicants must be U.S. citizens with two years of work in toward a doctoral after already

False GPS signals that deceive on-board plane systems and complicate the work of airline pilots are surging near conflict zones, industry employees and officials told AFP. A ground collision alert sounds in the cockpit, for instance, even though the plane is flying at high altitude - a phenomenon affecting several regions and apparently of military origin. This includes the vicinity of

In a study published in The Astrophysical Journal, researchers from the Yunnan Observatories of the Chinese Academy of Sciences depicted a complete physical image of the anomalous heating in the upper atmosphere of the Sun - the solar corona and the solar chromosphere. The enigma of the corona's anomalous heating stands as one of the eight challenges in modern astronomy. Similarly, the ano

Sound waves thought to be from a 2014 meteor fireball north of Papua New Guinea were almost certainly vibrations from a truck rumbling along a nearby road, new Johns Hopkins University-led research shows. The findings raise doubts that materials pulled last year from the ocean are alien materials from that meteor, as was widely reported. "The signal changed directions over time, exactly ma
