Gravity Holds on Cosmic Scales A new analysis of galaxy-cluster motions using the Atacama Cosmology Telescope shows that gravity weakens with distance almost exactly as Newton’s inverse-square law and Einstein’s general relativity predict, even across hundreds of millions of light-years. The result, published in Physical Review Letters, is the largest-scale test of the gravitational force … Read more
Gravity Holds on Cosmic Scales A new analysis of galaxy-cluster motions using the Atacama Cosmology Telescope has tested gravity across hundreds of millions of light-years and found it follows Newton’s inverse-square law and Einstein’s general relativity almost exactly. The result, published in Physical Review Letters, is the largest-scale test of the gravitational force law to … Read more
Little Big Bang from Light Nuclei Researchers at CERN’s ALICE experiment have produced quark-gluon plasma—the ultra-hot state of matter that filled the early Universe—by colliding oxygen-16 and neon-20 nuclei at near light speed. Previously, scientists assumed only heavy nuclei such as lead could generate this primordial “soup.” The particle flow patterns left after the brief … Read more
Self-Bound Quantum Droplets from Bose-Fermi Mixtures Researchers at Monash University have theoretically predicted stable, self-bound quantum droplets formed from mixtures of bosons and fermions under strong interactions. The work, published in Physical Review Letters and reported on 21 August, shows that attractive forces between the particles can be precisely balanced by fermionic pressure, preventing collapse … Read more
Diamond Melting Resolved at Extreme Pressures Lawrence Livermore National Laboratory researchers used laser-driven shock compression at the Omega facility to measure diamond’s atomic structure, temperature, density and reflectivity at pressures exceeding those inside Neptune and Uranus, and hotter than the Sun’s surface. Published in Nature Physics on 20 August, the work ends a 20-year mismatch … Read more
Quantum Simulator Measures Universal Energy Spectra Researchers at Caltech and collaborators have used a neutral-atom quantum simulator to make the first direct measurements of energy levels predicted by Ising and tricritical Ising conformal field theories. The results, published in Nature and reported 19 August 2026, confirm universal patterns that emerge at quantum critical points near … Read more
The Trillion-Dollar Treadmill, Updated (August 2026) What the arithmetic still says — and why the markets are starting to look nervous There is a number at the centre of the artificial-intelligence boom that almost no one likes to say out loud. Once you write it down, the whole thing starts to look strange. So let … Read more
Evidence of Quantum Vacuum Birefringence from a Magnetar Astronomers using NASA’s IXPE X-ray polarimeter, supported by radio data from CSIRO’s Parkes telescope, report strong polarization signatures from the magnetar 1E 1547.0-5408 that match predictions of vacuum birefringence. The effect, first outlined by Heisenberg nearly 90 years ago, arises when an extreme magnetic field aligns virtual … Read more
New Effective Theory Rebuilds Fluid Dynamics from Symmetries Physicists have completed a two-decade effort to reconstruct the theory of fluids from microscopic principles using effective field theory and symmetries. The work derives the classic Navier-Stokes equations as a consequence of fundamental symmetries rather than an ad-hoc continuum approximation, and it predicts new behaviors arising from … Read more
Gluon Junction May Carry Proton’s Baryon Number Data from the STAR detector at Brookhaven’s Relativistic Heavy Ion Collider, analyzed in a study published in Science and reported 16 August 2026, indicate that a Y-shaped junction of gluons—not the three valence quarks—primarily carries and conserves baryon number inside protons. In high-energy nuclear collisions, excess baryons appear … Read more
