Major developments in science, spaceflight, biomedicine, and climate/energy research for May 24, 2026, with summaries, links, and brief commentary.
I. Spaceflight & Deep Space
1. Shenzhou 23 reaches orbit: Hong Kong’s first astronaut, plus China’s first planned one-year station stay
Summary:
According to the China Manned Space Agency and state media (Xinhua), at 23:08 Beijing time on May 24, 2026, a Long March 2F Y23 rocket lifted off from Jiuquan and inserted the Shenzhou 23 crew spacecraft into its planned orbit, declared a success. The crew is commander Zhu Yangzhu, pilot Zhang Zhiyuan, and payload specialist Lai Ka-ying (Hong Kong). After insertion, the spacecraft followed procedures for autonomous fast rendezvous and docking with the space station complex. The mission is the seventh crewed flight of the station application & development phase and the 40th crewed spaceflight of the program; officials also state one crew member will carry out a roughly one-year on-orbit residency experiment to support long-duration human spaceflight medicine and engineering.

Commentary:
Pairing autonomous fast rendezvous with an explicit one-year stay moves Tiangong from steady crew rotation toward longer-timescale human–system validation.
II. Condensed Matter & Quantum Materials
2. Nature Physics: angular momentum transfer among lattice modes and a rotational Umklapp-like picture in Bi₂Se₃
Summary:
An international collaboration (including Helmholtz-Zentrum Dresden-Rossendorf and the Max Planck Fritz Haber Institute) uses intense terahertz pulses to coherently drive the IR-active Eu phonon in bismuth selenide and tracks the coupled Raman-active Eg mode. The experiment resolves a helicity reversal under sum-frequency phononic coupling, interpreted with discrete rotational symmetry as a conserved “crystal angular momentum” story; the authors connect the mechanism to magnetization equilibration, spin–lattice relaxation, and ultrafast control of material responses. The work appears in Nature Physics.

Commentary:
This is a direct view of phonon angular momentum flow between modes, giving axial nonlinear phononics a concrete, reproducible testbed beyond inferred magneto-optic proxies.
3. Science: nodeless superconducting gap and electron–boson coupling fingerprints in bilayer nickelate films
Summary:
A USTC-led team with Southern University of Science and Technology collaborators reports ARPES measurements on Ruddlesden-Popper bilayer nickelate superconducting thin films, evidencing a nodeless superconducting gap and a dispersion kink ~70 meV below the Fermi level consistent with electron–boson coupling. Published online in Science on May 21, 2026, the results sharpen constraints on pairing symmetry and pairing mechanisms in nickelate high-Tc superconductivity.

Commentary:
The field’s debate shifts from “node or not” toward identifying the bosonic mode set and how nickelates align with—or diverge from—the cuprate playbook.
III. Biomedicine & Health
4. NEJM: Phase 3 OCEANIC-STROKE reports asundexian cuts recurrent non-cardioembolic stroke without a clear major-bleeding penalty
Summary:
In this Bayer-funded, randomized, double-blind trial, 12,327 patients within 72 hours of non-cardioembolic stroke or high-risk TIA received asundexian 50 mg once daily or placebo on top of planned antiplatelet therapy. Ischemic stroke occurred in 6.2% vs 8.4% (cause-specific HR 0.74; 95% CI 0.65–0.84; P<0.001). ISTH major bleeding was 1.9% vs 1.7%, not indicating a prespecified harm signal in the published summary. Authors conclude asundexian reduces recurrent stroke and selected cardiovascular composites in this population.

Commentary:
Factor XIa inhibition now has a large Phase 3 “fewer strokes without obvious bleeding tax” story in secondary prevention; next questions are patient selection, durability, and comparative effectiveness.
5. Eli Lilly details TRIUMPH-1 Phase 3 weight-loss outcomes for retatrutide (80 weeks)
Summary:
According to a May 24, 2026 report in The Week, Lilly announced Phase 3 TRIUMPH-1 results for the GIP/GLP-1/GCG tri-agonist retatrutide in adults with obesity or overweight and weight-related comorbidities without diabetes: 2,339 participants randomized to placebo or weekly 4 mg, 9 mg, or 12 mg (titrated) for 80 weeks. The article cites company-reported mean weight losses of ~19.0%, ~25.9%, and ~28.3% at 4 mg, 9 mg, and 12 mg, respectively, with ~45.3% of the highest-dose arm reaching ≥30% weight loss; adverse events resemble other incretin-class agents, dominated by GI effects.

Commentary:
Efficacy keeps ratcheting upward in the incretin era; regulators and clinicians will focus on cardiovascular outcomes, durability after withdrawal, tolerability, and access.
IV. Climate, Energy & Earth Systems
6. Nature Energy: integrated planning of net-zero power systems “for all” (GISPO-class global model)
Summary:
Zhu Ziheng (Tsinghua University) and coauthors publish a globally resolved power-system model (~0.25°×0.25°, 8,760 hours) co-optimizing capacity expansion and operations. They report that net-zero systems meeting universal electricity needs for decent living standards appear technically feasible with roughly 15–20 TW of variable renewables, and highlight international transmission expansion, technology trade, demand-side management, and land-use planning as levers for cost and equity. Open code and reproduction assets are advertised on the lead author’s publication page.

- TechXplore — Global renewable electricity pathways
Commentary:
The paper compresses “is global net-zero electricity plausible?” into an auditable accounting exercise spanning land, grids, and trade—useful for national planners arguing from shared assumptions.
7. Nature: deep-learning satellite mapping builds a national wind/solar inventory for China and quantifies integration gains
Summary:
English-language newswire and newspaper coverage describes a Nature paper led by Yuan Hu (Peking University) with Alibaba DAMO Academy and other coauthors, using deep learning on sub-meter satellite imagery (~7.56 TB processed) to inventory China’s wind and solar assets as of 2022 (319,972 PV facilities and 91,609 wind turbines across 1,915 counties, per the paper abstract). News summaries quote modeled integration benefits under flexibility assumptions, emphasizing that nationwide inter-provincial coordination can materially reduce curtailment versus more provincially fragmented strategies.

- Nature — Advancing solar and wind penetration in China through energy complementarity
Commentary:
Grid operators cannot optimize what they cannot see; a credible national asset basemap is prerequisite infrastructure for dispatch, finance, and climate accounting at scale.
V. Animal Cognition & Fundamental Theory
8. PLOS ONE (discussed in press): beluga whales show MSR-like behavioral stages in archived mirror tests
Summary:
Ars Technica summarizes a PLOS One study digitizing decades-old underwater video from a New York aquarium: belugas Natasha and Maris show exploratory and self-directed behaviors in front of a two-way mirror consistent with mirror self-recognition staging; one animal also shows mark-oriented behavior. The reporting stresses ongoing debate about whether MSR is a good proxy for “self-awareness,” while noting this is the first systematic MSR-style case made for belugas.
Links:
Commentary:
Methodologically it is “late rigor on legacy footage”; scientifically it nudges cetacean cognition evidence while underscoring that field ethology should complement lab-style MSR.
9. Theoretical work: charged, radiating black holes may avoid both singularities and Cauchy horizons (preprint / press coverage)
Summary:
Francesco Di Filippo (Institute for Theoretical Physics, Goethe University Frankfurt) develops a formal model in arXiv:2510.20649 for a charged, spherically symmetric black hole formed by collapse with Hawking radiation, arguing electromagnetic repulsion combined with energy-condition violations from radiation can weaken standard singularity arguments so that neither a curvature singularity nor a Cauchy horizon need form in some regimes; an analogy to astrophysical spin is discussed. Science-news outlets including Phys.org summarize the work and note a Physical Review Letters publication; the arXiv PDF remains the openly accessible primary text used here.
Links:
- arXiv — Radiating black holes in general relativity need not be singular
- Phys.org — Charge, Hawking radiation, and interior pathologies
Commentary:
This is a careful re-examination of theorem boundaries in theory space; empirical leverage still requires independent observational handles on black-hole interiors and evaporation physics.
VI. Chemical Engineering & Clean Hydrogen
10. Birmingham-led study on medium-temperature perovskite thermochemical water splitting
Summary:
Researchers at the University of Birmingham and collaborators report Ba₂Ca₀.₆₆Nb₁.₃₄₋ₓFeₓO₆₋δ perovskites for thermochemical hydrogen production at medium temperatures (reported roughly 150–500 °C for splitting cycles, with regeneration at higher temperatures) in the International Journal of Hydrogen Energy. Popular summaries highlight possible competitiveness versus electrolytic “green” hydrogen and methane-based “blue” hydrogen under some electricity-price assumptions, and the prospect of using industrial waste heat to produce hydrogen near demand.

- SciTechDaily — Lower-temperature thermochemical hydrogen route
Commentary:
If cyclability and scale-up engineering hold, distributed, waste-heat-driven hydrogen could complement—not replace—electrolysis in hard-to-abate industrial clusters.
