XENONnT's Ionization-Only Search Tightens Limits on Few‑GeV Dark Matter
XENONnT's 7.8 tonne‑year ionization‑only search finds no dark‑matter signal, setting stronger limits on few‑GeV candidates and edging toward the solar‑neutrino floor.
Reanalysis Challenges DESI’s Claimed Signal for Dynamical Dark Energy
A new arXiv reanalysis finds DESI’s apparent hint of evolving dark energy is concentrated in one redshift bin and vanishes under alternate statistical checks.
Amazon says custom chips surpass $25 billion annual run rate as Trainium and Graviton power AWS AI
Amazon reports its custom-silicon business topped a $25B annualized run rate, citing Trainium, Graviton and multi-year AI customer commitments.
Sony to Stop Making Physical PlayStation Game Discs for New Releases from January 2028
Sony will discontinue producing physical discs for new PlayStation games released from January 2028, shifting future titles to digital-only sales.
NASA Opens First Major New Wind Tunnel at Langley in Over 40 Years
NASA opened the Flight Dynamics Research Facility at Langley Research Center, a modern wind tunnel to test aircraft, drones and reentry vehicles.
EU to Begin Enforcing AI-Transparency Rules on Aug. 2, 2026
From Aug. 2, companies serving the EU must disclose AI interactions and mark synthetic audio, image, video and text under Article 50 — violations face heavy fines.
Coinkite Warns Weak Randomness in Coldcard Firmware May Have Exposed Some Bitcoin
Coinkite says a 2021 firmware bug weakened seed randomness on older Coldcard devices, possibly exposing wallets; affected users must generate new seeds.
DESI preprint reports 1% measurement of the universe’s expansion at redshift 2.33
DESI's new preprint reports a 1% measurement of cosmic expansion geometry at z=2.33 from the Lyman‑alpha forest, tightening high‑redshift anchors for H0 and Ωm.
Pfizer says Phase 3 LITFULO trials met key vitiligo endpoints; plans global regulatory filings
Pfizer said Phase 3 trials of LITFULO (ritlecitinib) met key endpoints in nonsegmental vitiligo across 2,174 patients, and it plans global regulatory filings.
AI agents can run experiments and draft papers but fail to produce publishable research, study finds
A new preprint shows AI agents can handle engineering tasks—code, experiments and paper drafts—but failed to make publishable advances in two NeurIPS case studies.
Slovenian preprint claims light-programmable superconductivity in aluminium–silicon devices
A Slovenian arXiv preprint reports persistent, erasable superconductivity in aluminium–silicon devices controlled by ultrafast laser pulses; claims remain unverified.
New calculation narrows muon g-2 anomaly and refocuses debate on hadronic inputs
A 2026 Nature calculation brings the Standard Model into agreement with muon g‑2 measurements, shifting the controversy to hadronic vacuum polarization inputs.
