How to force photons to never bounce back
Topological insulators are materials whose structure forces photons and electrons to move only along the material's boundary and only in one direction. These particles experience little resistance and travel freely past obstacles such as impurities,.....»»
Engineers smash rocks to see what occurs when top layer of an asteroid-like object is hit with extreme external force
Johns Hopkins engineers have uncovered new details about how granular materials such as sand and rock behave under extreme impacts—findings that could someday help protect the Earth from dangerous asteroids......»»
Space Command chief says dialogue with China is too often a one-way street

Upgraded atomic force microscope captures 3D images of calcite dissolving
Understanding the dissolution processes of minerals can provide key insights into geochemical processes. Attempts to explain some of the observations during the dissolution of calcite (CaCO3) have led to the hypothesis that a hydration layer forms, a.....»»
Powerful Typhoon Shanshan slams into southern Japan
Typhoon Shanshan hit Japan with full force on Thursday, injuring dozens as howling winds smashed windows and blew tiles off houses while torrential rains turned rivers into raging torrents......»»
Scientists create ultracompact polarization-entangled photon sources for miniaturized quantum devices
Scientists have created an ultra-thin light source that emits pairs of polarization-entangled photons. These specially correlated photons hold promise for future quantum technologies, including ultra-secure communication, powerful computation, and hi.....»»
Nonprofits with investment income slower to recover from economic downturns, study shows
A recent study evaluates three decades of financial data from nonprofit organizations and finds that while the sector tends to bounce back quickly after periods of economic recession, some organizations bounce back more quickly than others. Specifica.....»»
Physicists ease path to entanglement for quantum sensing
Nothing in science can be achieved or understood without measurement. Today, thanks to advances in quantum sensing, scientists can measure things that were once impossible to even imagine: vibrations of atoms, properties of individual photons, fluctu.....»»
Wolves vs Chelsea live stream: Can you watch for free?
After each suffering a 2-0 defeat to open the 2024-25 Premier League season, Wolves and Chelsea look to bounce back when they meet up at Molineux Stadium today. The match starts at 9:15 a.m. ET, and in the United States it will stream exclusively on.....»»
Researcher explores how you can stretch your mind to grasp quantum entanglement
My new article, "Quantum Entanglement of Optical Photons: The First Experiment, 1964–67," is intended to convey the spirit of a small research project that reaches into uncharted territory. The article breaks with tradition, as it offers a first-pe.....»»
Study uncovers condensed-matter dark states in a quantum system with two pairs of sublattices
Dark states are quantum states in which a system does not interact with external fields, such as light (i.e., photons) or electromagnetic fields. These states, which generally occur due to interferences between the pathways through which a system int.....»»
Disney cancels The Acolyte after one season
Star Wars series was admittedly uneven, but didn't deserve the online hate it received. Enlarge / We have doubts that any amount of Force powers will bring the show back. (credit: YouTube/Disney+) In news that will del.....»»
The evolution of the Trappist-1 planetary system
Planets are bodies that orbit a star and have sufficient gravitational mass that they form themselves into roughly spherical shapes that, in turn, exert gravitational force on smaller objects around them, such as asteroids and moons......»»
NASA CubeSats launch as commercial rideshares
A pair of CubeSats from NASA's Pathfinder Technology Demonstrator, or PTD, series lifted off on SpaceX's Transporter-11 rideshare mission at 11:56 a.m. PDT Friday, August 16, from Vandenburg Space Force Base in California......»»
TikTok ban: ByteDance says app is run and controlled in US, not China
ByteDance’s appeal against a US TikTok ban is underway, and the company has accused the Department of Justice of factual errors in presenting its case – intended to force the sale of the app to an American company. The DOJ says the app’s fee.....»»
Rocket Report: ULA is losing engineers; SpaceX is launching every two days
The first missions of Stoke Space's reusable Nova rocket will fly in expendable mode. Enlarge / A Falcon 9 booster returns to landing at Cape Canaveral Space Force Station following a launch Thursday with two WorldView Earth obse.....»»
Favorite tech for remote working and travel [Video]
Every year, more and more people are given the ability to work remotely. Some just set up an office in their homes, others bounce around coffee shops and coworking spaces, and others work while traveling. Even though I like to change up my work envir.....»»
Theoretical research holds promise for advancing modular quantum information processing
The operation of a quantum computer relies on encoding and processing information in the form of quantum bits—defined by two states of quantum systems such as electrons and photons. Unlike binary bits used in classical computers, quantum bits can e.....»»
