ATLAS Experiment probes the quark-gluon plasma in a new study of photo-produced muon pairs
At the Large Hadron Collider (LHC) at CERN, the electromagnetic fields of Lorentz-contracted lead nuclei in heavy-ion collisions act as intense sources of high-energy photons, or particles of light. This environment allows particle physicists to study photon-induced scattering processes, which can not be studied elsewhere. …
Tom DeLonge’s UFO Research Group Signs Contract With US Army To Develop Far-Future Tech
Blink-182 singer Tom DeLonge’s UFO research organization has signed an agreement with the U.S. Army in which it will help the military study and develop advanced materials for the purposes of develpoing “active camouflage, beamed energy propulsion, and quantum communication” for use on military vehicles. Motherboard reports: On October 17th, To the Stars joined forces with the Army’s Combat Capabilities Development…
Radiation detector with the lowest noise in the world boosts quantum work
Researchers from Aalto University and VTT Technical Research Centre of Finland have built a super-sensitive bolometer, a type of thermal radiation detector. The new radiation detector, made of a gold-palladium mixture makes it easier to measure the strength of electromagnetic radiation in real time. Bolometers are used widely in thermal cameras in the construction industry and in satellites to measure cosmic…
Pager Services To End Tuesday In Japan After 50 Years
Japan’s sole pager provider, Tokyo Telemessage Inc, will shut down radio signals for its services Tuesday, ending support for the device first introduced in the country half a century ago. Japan Today reports: In recent years, the device had been favored mainly by those working in hospitals, where cellphone use was once discouraged because of concerns over the effect of electromagnetic…
Astronomer probes idea of ET ‘lurkers’
What would an extraterrestrial intelligence need to observe Earth, long-term, from nearby? Materials, a firm anchor, concealment? Earth’s co-orbital objects, or quasi-satellites, might be the ideal place to “lurk.” Source: https://earthsky.org/space/alien-lurker-probes-co-orbital-asteroids-earth…
Why carbon dioxide has such outsized influence on Earth’s climate
Carbon dioxide, CO2, makes up less than one-twentieth of 1% of Earth’s atmosphere. How does this relatively scarce gas control Earth’s thermostat? Source: https://earthsky.org/earth/why-carbon-dioxide-co2-influence-earths-climate-greenhouse-effect…

Making sense of Saturn’s impossible rotation
Saturn may be doing a little electromagnetic shimmy and twist which has been throwing off attempts by scientists to determine how long it takes for the planet to rotate on its axis, according to a new study. Source: https://phys.org/news/2019-09-saturn-impossible-rotation.html…
Study shows the non-exponential decay of a giant artificial atom
To date, research in quantum optics has primarily investigated the relation between light and matter using small atoms interacting with electromagnetic fields that have substantially larger wavelengths. In an unconventional new study, a team at Chalmers University of Technology in Sweden and the Max Planck Institute for the Science of Light set out to explore the interaction between a large atom…
