Yes, I know, we know this, all of this, but it's good to see it documented like this.

"This is the first-ever observation of entanglement between a pair of quarks and the highest-energy measurement of entanglement. Apart from the fundamental interest of testing quantum entanglement in a new environment, this measurement paves the way to use the LHC as a laboratory to study quantum information and other foundational problems in quantum mechanics."

The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerators with a 27km circumference with over 9,000 magnets that can generate 9 billion collisions per second.

There is even a !boinc@sopuli.xyz project where you can contribute your computer’s spare computational power to analyzing the huge mass of data this project generates, no PhD required! Each year of operation generates approx 30 petabytes of data, equivalent to 1.2 million bluray disks.

Like rivers feeding oceans, streams of gas nourish galaxies throughout the cosmos. But these streams, which make up a part of the so-called cosmic web, are very faint and hard to see. While astronomers have known about the cosmic web for decades, and even glimpsed the glow of its filaments around bright cosmic objects called quasars, they have not directly imaged the extended structures in the darkest portions of space—until now. https://doi.org/10.1038/s41550-023-02054-1

When a microbe was found munching on a plastic bottle in a rubbish dump, it promised a recycling revolution. Now scientists are attempting to turbocharge those powers in a bid to solve our waste crisis. But will it work?

In the 19th century, miners in southern Spain unearthed a prehistoric burial site in a cave containing some 22 pairs of ancient sandals woven out of esparto (a type of grass). The latest radiocarbon dating revealed that those sandals could be 6,200 years old—centuries older than similar footwear found elsewhere around the world, according to a new paper published in the journal Science Advances. The interdisciplinary team analyzed 76 artifacts made of wood, reeds, and esparto, including basketry, cords, mats, and a wooden mallet. Some of the basketry turned out to be even older than the sandals, providing the first direct evidence of basketry weaving among the hunter-gatherers and early farmers of the region.

ABSTRACT: The independent modulation of visible and near-infrared light by a single material, termed dual-band electrochromism, is highly desirable for smart windows to enhance the energy efficiency of buildings. Tungsten oxides are commercially important electrochromic materials, exhibiting reversible visible and near-infrared absorption when electrochemically reduced in an electrolyte containing small cations or protons. The presence of structural water in tungsten oxides has been associated with faster electrochromic switching speeds. Here, we find that WO3·H2O, a crystalline hydrate, exhibits dual-band electrochromism unlike the anhydrous WO3. This provides a heretofore unexplored route to tune the electrochromic response of tungsten oxides. Absorption of near-infrared light is achieved at low Li+/e– injection, followed by the absorption of visible light at higher Li+/e– injection as a result of an electrochemically induced phase transition. We propose that the dual-band modulation is possible due to the more open structure of WO3·H2O as compared to WO3. This facilitates a more extended solid-solution Li+ insertion regime that benefits the modulation of near-infrared radiation via plasmon absorption. Higher degrees of Li+/e– insertion lead to polaronic absorption associated with localized charge storage. These results inform how structural factors influence the electrochemically induced spectral response of transition-metal oxides and the important role of structural water beyond optical switching speed.
