A precise proton measurement helps put a core theory of physics to the test: « The standard model of particle physics is confirmed to a tenth of a billionth of a percent. » Read Full Article #ParticlePhysics #StandardModel #PrecisionMeasurement #FundamentalForces…
⚛️ A new measurement of the proton's radius, reported February 11 in Nature, is precise enough to test a fundamental theory of particle physics.
🔬 Scientists measured the radiation frequency needed to shift hydrogen atoms between energy levels, revealing a proton radius of about 0.84 trillionths of a millimeter. This confirms a smaller proton size and rules out larger measurements from earlier experiments.
✨ This precise measurement allowed researchers to test the standard model of particle physics, confirming its predictions to better than a tenth of a billionth of a percent, specifically validating quantum electrodynamics.

The loud squeaks of shoes on a basketball court result from parts of the sole slipping in pulses that repeat thousands of times a second Read Full Article #courtnoises #sneakerloops #squeakscience #basketballmotion #gameaudioeffects
👟 Physicists have discovered the "stick-slip" motion behind basketball shoe squeaks. This is a stop-and-go process where parts of the sole stick while others slide, creating regular pulses that generate the sound.
🔬 High-speed video revealed that these pulses, repeating about 4,800 times per second, alter air pressure to create the squeak. The rate of these pulses directly matches the sound's frequency and pitch.
💡 Research showed that ridges on a sneaker's tread are crucial for a clear squeak. The thickness and stiffness of the sole influence the pitch, suggesting silent shoes could be made by tuning the squeak to inaudible ultrasound frequencies.

Flexible feline spines shed light on “falling cat” problem | Torsional flexibility of the thoracic spine is superior to that of the lumbar spine in cats: Implications for the falling cat problem Read Full Article Here are 5 hashtags for your post:#FelineFlexibility…
🐈 Scientists continue to study why falling cats land on their feet, with new experiments published in The Anatomical Record analyzing feline spine flexibility. This phenomenon has been debated since at least 1700.
🐈 Previous theories include the "tuck and turn," "falling figure skater," "bend and twist," and "propeller tail" mechanisms. Physicist Greg Gbur previously emphasized the "bend and twist" as most important, but recent findings might lend more credence to the "tuck and turn."

Antimatter has been transported by road for the first time Read Full Article #Antimatter #SciTech #PhysicsNews
🔬 ~100 antiprotons successfully completed a 20-minute test journey on a truck at CERN, marking a first step towards a future antimatter delivery service to labs across Europe.
🧪 This pioneering transport, part of the STEP project, involved moving 92 antiprotons from CERN's "antimatter factory" and back, showcasing the potential for more precise antimatter experiments in magnetically quiet locations.
💡 Scientists aim to use this technology to better understand antimatter's properties and the dominance of matter in our universe, with future long-distance transports planned after CERN's LHC upgrades are complete by the end of 2028.

The depths of Neptune and Uranus may be “superionic”: « Sophisticated models predict that a quasi-one-dimensional superionic state of carbon hydride exists under the extreme pressures and temperatures found deep inside Neptune and Uranus. » Read Full Article…
🚀 New simulations by Carnegie’s Cong Liu and Ronald Cohen suggest a previously unknown state of matter may exist deep within ice giant planets like Uranus and Neptune.
🔬 Published in Nature Communications, their research predicts a quasi-one-dimensional superionic state of carbon hydride under extreme pressures (500-3,000 gigapascals) and temperatures (6,740-10,340°F) found in these planets' interiors.
✨ This state features a carbon framework with hydrogen atoms moving along spiral pathways, influencing heat/electricity transfer and potentially planet magnetic field generation.

🔬 Scientists at NIST have published new results in the journal Metrologia concerning the gravitational constant ("Big G").
🔬 This latest experiment, which took a decade to complete, aimed to replicate previous divergent results but does not resolve the long-standing discrepancy in the value of Big G.
🔬 Measuring Big G precisely is challenging due to gravity's extreme weakness compared to other fundamental forces, leading to significant background noise from Earth's own gravity.

South Korean students discovered that the First Law of Thermodynamics applies in black holes. Read Full Article #Thermodynamics #BlackHoles #PhysicsNews
✨ Three students from Seoul Science High School have published a groundbreaking paper on black hole thermodynamics in the International Journal of Modern Physics D. Their new approach, focusing on changes in entropy instead of volume, allows for a more natural derivation of the first law of thermodynamics for complex black holes, potentially supporting the theory of emergent gravity.
🗓️ The research, titled “A Constraint-Free Formulation of Black Hole Thermodynamics from the Field Equations,” was submitted in January and published in June. The paper was developed through the school's regular curriculum and research programs, with guidance from physics teacher Kwon Yong-joon.
🎓 The students, Ahn Geon-woo, Bae I-jin, and Jang Geun-young, who graduated in February, were praised by reviewers for their sophisticated research, a rare achievement for high schoolers without university support.

Breaking: Physicists May Have Found The Best Evidence of Dark Matter Yet Read Full Article #DarkMatter #PhysicsNews #AstroPhysics
✨ A potential dark matter signal has been detected by the LUX-ZEPLIN (LZ) experiment, deep underground. This signal, a tiny flash of light observed on June 16, 2023, has characteristics consistent with weakly interacting massive particles (WIMPs), a leading dark matter candidate.
✨ Physicists are cautiously optimistic but emphasize the result is not yet peer-reviewed and has a statistical significance of 2.6 sigma, meaning a 1 in 200 chance of being a random background event, rather than the 5-sigma threshold required for a discovery.
✨ The LZ experiment uses a large tank of liquid xenon, shielded by kilometers of rock and other detectors, to minimize background noise and search for the rare instances where a WIMP might collide with an atom, producing a detectable flash of light.
