Oxford preprint finds GraphCast and NeuralGCM fail basic coordinate-change tests
An Oxford preprint on arXiv reports GraphCast and NeuralGCM fail latitude/longitude flips and rotations, raising questions about physical generalization.
GAO: NASA’s Major Projects Mostly Stable, but Artemis Overhaul, Staffing Cuts Raise Risk
GAO review finds NASA’s 36 major projects largely steady, but Artemis changes, 22% workforce cuts and a proposed 23% budget cut increase program risk.
GAO: Energy Department’s Isotope Program Fails to Align Production With Market Needs
A GAO report finds DOE’s isotope program isn’t systematically matching production to demand, risking medical, security and industrial supplies.
Revised DESI reanalysis suggests unusually tight cosmological bounds on neutrino mass, favors normal ordering
A revised DESI reanalysis reports unusually tight cosmological limits on the sum of neutrino masses that favor the normal ordering, but the result is preliminary.
Juno Measures First Below‑Surface Temperatures on Io, Finds Intense Shallow Heating
Juno's microwave radiometer probed inches to tens of feet below Io’s surface and found unexpectedly strong shallow heating.
White House Announces Expansion of Genesis Mission, Citing More Than $5 Billion in Federal Commitments
On July 22 the White House expanded the DOE-led Genesis Mission, citing more than $5 billion in federal commitments and 278 selected AI-for-science projects.
Analysis of 168 Gravitational-Wave Events Finds No Break in Einstein’s General Relativity
A LIGO-Virgo-KAGRA analysis of 168 high-confidence mergers finds no deviations from general relativity, tightening previous constraints.
NASA and ISRO Open First Broad Release of Calibrated NISAR Radar Data
NASA and ISRO have begun public release of calibrated L‑ and S‑band radar products from the NISAR satellite, giving researchers wider access to Earth and ice observations.
Preprint reports near-quantized photocurrent in nickel-doped RhSi
An arXiv preprint reports a near-quantized circular photogalvanic effect in Rh0.95Ni0.05Si, suggesting topology may fix an optical response even without an energy gap.
Boulder team reports optical clock comparisons hitting 3.2×10⁻¹⁸ uncertainty, a milestone toward redefining the second
Researchers in Boulder compared three optical atomic clocks with uncertainties down to 3.2×10⁻¹⁸, meeting a benchmark for redefining the SI second.
Preprint Claims Ultrafast Lasers Can Create 'Programmable' Superconductivity at Aluminum–Silicon Interface
An arXiv preprint claims femtosecond laser pulses can create, erase and tune a phase-coherent superconducting state at an aluminum-silicon interface; unreviewed.
Study: CubeSat-sized inspector could, in principle, verify ban on nuclear weapons in orbit
MIT modeling shows a 9U CubeSat with directional neutron detectors could, in principle, detect unshielded thermonuclear weapons in low Earth orbit.
Preprint Suggests Dark Matter–Dark Energy Interaction Could Explain DESI Anomalies
A revised arXiv preprint argues DESI-era tensions with ΛCDM may be explained by dark matter–dark energy interactions rather than evolving dark energy.
