JWST discovers a wide variety of carbon-rich gases that serve as ingredients for future planets around very low-mass stars

by

Artist’s impression of a protoplanetary disk around a very low mass star. It shows a selection of hydrocarbon molecules (methane, CH4; Ethan, C2H6; Ethylene, C2H2; Diacetylene, C4H2; Propyne, C3H4; Benzene, C6H6) detected on the disk around ISO-ChaI 147.

Composite image using high-resolution microscopy and spectroscopy showing the absorption and replacement processes of rare earth elements in the eggshell. Credit: Prof. Juan Diego Rodriguez-Blanco, Trinity College Dublin A collaborative team of researchers has made a groundbreaking discovery with the potential to have a significant impact on the sustainable recovery of rare earth elements (REEs), … Read more

Research suggests that the germanium isotope really does have a half-life of 11 days

by

Relevant parts of the spectra obtained on day 20 from the three measurements performed. Credit: Physical assessment C (2024). DOI: 10.1103/PhysRevC.109.055501 The search for the elusive neutrino takes many forms. Detectors consisting of many tons of gallium are used in various experiments because neutrino interactions can occur on the stable gallium-71 (71Ga) nucleus and transform … Read more

Towards testing the quantum behavior of gravity: a photonic quantum simulation

by

Artist’s representation of the implemented photonic experiment in which entanglement between the polarizations of individual photons is mediated by the independent degree of freedom of the photon path. In particular, mediated entanglement represents a core principle of future experiments with massive particles, aiming to explore the quantumness of gravity for the first time.

Webb telescope once again finds the most distant galaxy ever observed

by

The galaxy JADES-GS-z14-0, as seen by the James Webb Space Telescope, existed 290 million years after the Big Bang. The James Webb Space Telescope has discovered what appears to be a new record holder for the farthest known galaxy, a remarkably bright galaxy that existed just 290 million years after the Big Bang, NASA said … Read more

Combining theory and experiment to shed new light on proton spin

by

A global analysis of experimental data and Quantum Chromodynamics calculations of the lattice provides insight into the role of the gluons (purple coils) that contribute to the spin of the nucleon. Gluons are manifestations of the. Credit: Jefferson Lab Nuclear physicists have long been working to reveal how the proton gets its spin. Now, a … Read more

First topological quantum simulator device with a strong light-matter interaction regime operating at room temperature

by

Representation of the photonic topological insulator developed in the study. Credit: Rensselaer Polytechnic Institute Researchers at Rensselaer Polytechnic Institute have created a device no wider than a human hair that will help physicists probe the fundamental nature of matter and light. Their findings, published in the journal Nature Nanotechnologycould also support the development of more … Read more

Saturday quotes: Mediterranean diet gives you more points; persistent quantum coherence; vegan dogs

by

An artist’s impression of VFTS 243 in the Tarantula Nebula. Credit: ESO/L. Calcada. eso.org/public/images/eso2210a/ This week we reported on the birth of black holes, the dubious claims of a vegan dog study, and a technique to observe entanglement without breaking quantum coherence. Neutrino predict-ino When a large star burns up its core, it explodes in … Read more
