From mobile phones and banking systems to aircraft, ships and emergency services, much of modern life relies on precise timing signals from satellites. Known as the Global Navigation Satellite System (GNSS), satellites carrying atomic clocks transmit time-stamped...
It was a journey to the center of the Earth, if only for the briefest of moments. But rather than tunneling thousands of miles from Earth’s surface, researchers from Lawrence Livermore National Laboratory (LLNL) and several universities used the National...
Researchers from the Quantum Hardware group at CIC nanoGUNE, in collaboration with the British company Quantum Motion, have demonstrated an advanced readout sensor for spin qubits that, while being more compact than previous designs, can reach the level of readout...
Like a shelf in an old house, the Earth collects a lot of dust from its surroundings. This “space dust” is mostly made up of micrometeorites that survive atmospheric entry and provides researchers with a cheap and easy way to obtain samples to study our...
Researchers have created a special flat lens that shapes light into an optical needle—a thin beam that stays tightly focused over a long distance. Combining this lens, which is about 7 microns thick, with optical coherence tomography (OCT) could allow imaging that...
As crowds in Newport Beach grew, individuals blocked roadways and threw explosive mortars, fireworks and other projectiles at police officers, into densely packed crowds and near children Go to Source
Researchers working with data from the South Pole Telescope have released a major catalog of galaxy clusters, giving scientists a powerful new tool for studying how the universe grew and changed over billions of years. The findings are published on the arXiv preprint...
Bystander video posted online shows at least one person holding the North Charleston officer down while others punched her and struck her with objects Go to Source
The civil grand jury found that the Placer County Sheriff’s Office blocked the Auburn Police Department from receiving ALPR alerts for approximately two years Go to Source
NASA and China’s national space agency plan to send crewed missions to Mars in the coming decades. Per NASA’s Moon to Mars mission architecture, this will involve using infrastructure established through the Artemis Program to send crews to the red planet...
Electrons, negatively charged particles, sometimes coordinate their movements in ways that produce certain collective excitations referred to as quasiparticles. One case in which this occurs is the quantum Hall effect, a phenomenon that emerges when electrons are...
What began as a peaceful demonstration ended with five officers killed, several others wounded and a historic SWAT operation Go to Source
Where does the solar system end and interstellar space begin? That’s a question scientists have been working to answer using spacecraft traveling beyond the sun’s influence. A team of researchers from the Southwest Research Institute, led by Heather...
Astronomers using the James Webb Space Telescope have identified what may be the most distant barred spiral galaxy ever discovered, dating to a time less than 1.2 billion years after the Big Bang. The paper outlining its properties was posted to the arXiv preprint...
Physicists have long puzzled over a strange contradiction inside a family of minerals called rutile oxides. These materials all share the same crystal structure—but while some of them, like titanium dioxide, are firmly insulating, others, like ruthenium dioxide,...
