Overland Expo's focus may be largely on earth-exploring giants and burly, overbuilt hardware, but the show does highlight its fair share of light, ultra-portable outdoor gadgets. One of our favorite finds this year was the Fire Flute from Outdoor Element. Despite not even pushing the scale needle to 50 grams, the tool packs a fire starter rod, watertight cache and emergency whistle in a sleek bod
If you're comfortable with the present green, amber, and red traffic lights, be prepared to get uncomfortable. New research suggests that adding a white light will speed up traffic and improve safety for both cars and pedestrians.Continue ReadingCategory: ScienceTags: Autonomous Vehicles, North Carolina State University, Traffic
Researchers have developed a high-resolution sensor that records brain signals to decode what people are trying to say. While still early days, the device may provide people who’ve lost speech due to neurodegenerative disease with the ability to communicate.Continue ReadingCategory: ScienceTags: Brain-computer interface, Speech, Machine Learning, Duke University
Saab's new Ultra-Lightweight Camouflage Screen (ULCAS) is a net that allows soldiers to hide from radar sweeps, while still being able to receive GPS signals and radio communications.Continue ReadingCategory: Military, TechnologyTags: Saab, camouflage, Radar
Researchers have developed a new technique to better detect extraterrestrial radio signals by weeding out the interference caused by Earth-based devices. It’s hoped that the technique will lead to the discovery of the first evidence of life outside our planet.Continue ReadingCategory: Space, ScienceTags: SETI, Extraterrestrial, Radio Waves, Signal, University of California Berkeley
Radio telescopes are picking up strange radio signals from an intelligent lifeform – ourselves. A new study has shown that large satellite constellations, such as SpaceX’s Starlink swarm, are unintentionally leaking signals that can interfere with vital observations.Continue ReadingCategory: Space, ScienceTags: Astronomy, Radio, Radio Waves, Satellite, SpaceX, Starlink, Internet, Max Planck Insti
The James Webb Space Telescope has spotted complex organic molecules, which usually form in smoke and smog, in the very distant universe. With help from a galactic gravitational anomaly, the telescope could see the molecules from more than 12 billion light-years away.Continue ReadingCategory: Space, ScienceTags: James Webb Space Telescope, JWST, Molecules, Organic, Gravitational lensing, Galaxy,
A new study led by the University of Manchester suggests that if any alien civilizations are turning their radio telescopes toward Earth, they may be able to not only detect our mobile phone signals, but could deduce a lot about our planet and even produce crude maps of it.Continue ReadingCategory: Space, ScienceTags: University of Manchester, SETI, Radio, Extraterrestrial
Over the last 15 years or so, astronomers have detected hundreds of unexplained radio signals from space, which they call fast radio bursts (FRBs). Now a fresh look at radio telescope data has doubled the number of known sources, bringing us closer to solving the mystery.Continue ReadingCategory: Space, ScienceTags: Fast Radio Bursts, Radio, Astronomy, McGill University, Signal
It’s estimated that the universe contains hundreds of billions of galaxies, and each galaxy has about that many planets, so the chances are incredibly small that Earth is the only place with life. A new AI system has now scoured millions of radio signals from space to identify any with potential artificial origins – and discovered eight signals that look intriguingly alien.Continue ReadingCategor is a social bookmarking place where you can share, find & discuss the best news around on most topics.
