Science, space, biomedicine, and climate research highlights compiled for Sep 24, 2026, with summaries, links, and brief commentary.
I. Space & Deep Space
1. NASA selects far-infrared PRIMA as first astrophysics Probe mission (Mission selection)
Summary:
SpaceNews reported on Sep 24 that NASA has selected the Probe far-Infrared Mission for Astrophysics (PRIMA) as its first billion-dollar-class astrophysics Probe mission, aiming to restore far-infrared observing capacity between flagships and smaller spacecraft. PRIMA had previously advanced alongside the X-ray AXIS concept; AXIS was disqualified in March 2026, leaving the far-infrared path as the first pick for the new Probe line. The mission is framed as filling the far-infrared gap between JWST and future large flagships.

Commentary:
This locks a roadmap choice, not a launch date—budget, schedule, and instrument maturity will decide whether the far-infrared window truly reopens.
2. First radio emission firmly tied to an exoplanet: auroral signal from Beta Pictoris b (Exoplanets)
Summary:
WIRED reported on Sep 24 that a Harvard–University of Oregon team argues in a preprint that MeerKAT detections can be attributed to the young gas giant Beta Pictoris b (~63 light-years; several Jupiter masses), not host-star activity. The radio characteristics match predictions for auroral emission from charged particles in a young, massive planet’s magnetosphere; the authors say this is the first time such emission has been pinned directly to a known exoplanet. The study is not yet peer-reviewed, and the team stresses a natural origin, not technosignatures.

Commentary:
If it survives review, exoplanet magnetic fields move from inference toward direct “listening”—but stellar contamination and localization ambiguities remain open until peer review.
3. Perseverance: at least three water–rock episodes in Jezero’s Margin Unit, including hot groundwater (Mars)
Summary:
NASA and a Communications Earth & Environment paper report that Perseverance’s SuperCam surveyed more than 185 bedrock targets in Jezero’s Margin Unit and reconstructed at least three water–rock episodes: CO₂-rich groundwater forming carbonate-filled fractures; later lake water or evolving groundwater remobilizing carbonate and precipitating silica; and late hydrothermal fluids depositing fluorite-bearing calcium-sulfate veins (~25 cm thick). Fluorite typically signals hot fluids circulating through volcanic rock. The sequence can be ordered but not yet dated. The paper published Sep 21; NASA and science outlets continued coverage today.

Commentary:
The Margin Unit upgrades from “ancient shoreline” to a stacked groundwater–lake–hydrothermal habitability archive—absolute ages and sampling priority are the next puzzle pieces.
II. Biomedicine & Health
4. FDA approves Lilly’s once-weekly basal insulin Onswik for adults with type 2 diabetes (Metabolic disease)
Summary:
On Sep 24, Eli Lilly said the U.S. FDA approved Onswik (insulin efsitora alfa-gobe), a once-weekly subcutaneous basal insulin used with diet and exercise to improve glycemic control in adults with type 2 diabetes. It is designed to deliver steady basal coverage over seven days and, per Lilly’s 52-versus-365 injection estimate, can cut more than 300 injections per year versus daily basal insulin. Approval rests on the QWINT Phase 3 program in over 3,400 adults: once-weekly Onswik met non-inferior A1C reduction versus insulin glargine or degludec, with an overall safety profile similar to the daily basal controls. It is not for type 1 diabetes; EMA, Mexico, and Japan already approved it, and U.S. KwikPen availability is expected in coming months.
Links:
Commentary:
Non-inferiority approval buys adherence and injection burden relief, not “stronger glucose lowering”—real-world hypoglycemia and dosing errors will decide whether it rewrites basal-insulin routines.
5. Kyverna: one-year miv-cel durability in stiff-person syndrome supports year-end FDA filing (Cell therapy)
Summary:
BioSpace reported on Sep 24 that Kyverna’s registrational Phase 2 KYSA-8 one-year follow-up in 26 stiff-person syndrome (SPS) patients showed improved mobility and leg function with a favorable safety profile for mivocabtagene autoleucel (miv-cel), meeting primary endpoints. Median improvement from baseline was 46% at 16 weeks and 49% at 12 months; 95% of patients who had achieved a clinically meaningful (≥20%) gain sustained it; among 12 patients who entered needing a walking aid, 67% no longer required assistance. A rolling BLA is slated for completion this year with a priority-review request. Longer-term KYSA-6 myasthenia gravis data were also updated; neither study reported high-grade CRS/ICANS or IEC-HS, contrasting recent competitor pauses.
Links:
Commentary:
An approval would be the first marketed CAR-T for autoimmunity—durability and safety look strong, but small N and a narrow indication still constrain how far regulators will let labels travel.
6. Anthropic: Claude flags CRISPR-like bacterial enzyme system ART (AI-assisted discovery)
Summary:
Anthropic said Wednesday that, prompted by researchers at its new San Francisco biology lab, Claude spent about 21 hours searching large DNA databases and identified a reverse-transcriptase–centered system with CRISPR-like repeat arrays plus a protein of unknown function, dubbed ART (array-associated reverse transcriptases). The company said the underlying RT had been noted before, but Claude appears first to assemble the broader system features, and CEO Dario Amodei suggested it might “represent a new gene editing mechanism.” Function remains unknown. Al Jazeera and others covered the claim on Sep 24; Stanford’s Stanley Qi called the pattern recognition exciting, while Washington University’s Kevin Blake warned that “CRISPR-like” is not the next therapeutic CRISPR.

- The Star / Reuters — Anthropic says Claude AI helped discover novel enzyme system
Commentary:
A strong signal that AI can accelerate cataloguing and hypothesis generation—not that CRISPR 2.0 is in hand—until function, programmability, and wet-lab validation catch up.
III. Climate, Energy & Environment
7. Longi claims 28.29% single-junction silicon cell efficiency, ISFH-certified world record (Photovoltaics)
Summary:
pv magazine reported on Sep 24 that Chinese PV maker Longi achieved 28.29% conversion efficiency for a hybrid interdigitated-back-contact (HIBC) cell, verified by Germany’s Institute for Solar Energy Research Hamelin (ISFH)—a world record for single-junction crystalline silicon that tops Longi’s May mark of 28.13%. The company said it broke the record three times this year (28.04%, 28.13%, 28.29%), reaching about 96.2% of the theoretical limit. Architecture details from prior work include passivated tunneling contacts, dielectric passivation, n/p contacts, and edge passivation; Longi says scale-up to heterojunction manufacturing is plausible but still needs lower p-type contact resistive losses.

Commentary:
Lab records are pressing against silicon’s ceiling—manufacturing yield and cost curves are what the grid will actually feel from the next hundredths of a percent.
8. Modeling: expanding Gobi solar farms could cut northern China’s spring dust ~14% (Climate & air quality)
Summary:
Work by Yueting Hao of Nanjing University and colleagues in Geophysical Research Letters (DOI: 10.1029/2026GL124605), covered by phys.org on Sep 24, finds large Gobi solar arrays can slow near-surface winds and stabilize soil, suppressing dust lofting. Existing farms are estimated to cut spring dust emissions by about 352,400 metric tons per month and downwind transport into northern China by about 131,400 metric tons per month. Under a 2060 carbon-neutrality expansion (~11× current Gobi solar area), the model projects ~12% lower dust emissions and ~21% less transport, with average spring concentrations of larger particles (up to 10 µm) across northern China falling by about 14%.

Commentary:
Clean power plus air-quality co-benefits is an appealing dual dividend—but it rests on scenarios and regional meteorology, so field validation and ecological side effects still need watching.
IV. Basic Research & Planetary Science
9. Nature: Singapore Lu+ optical clocks verified at the 19th digit with record same-species comparison (Quantum metrology)
Summary:
A National University of Singapore Centre for Quantum Technologies team led by M. D. Barrett published in Nature on Sep 23 two independently built ¹⁷⁶Lu⁺ single-ion optical frequency references, each with evaluated fractional uncertainty near 1×10⁻¹⁹. Correlation spectroscopy found agreement of [−0.1 ± 5.7stat ± 1.0sys]×10⁻¹⁹—among the most precise same-species optical-clock comparisons reported. The room-temperature systems support SI-second redefinition discussions, millimetre-scale chronometric geodesy, and tests of relativity and dark matter. NUS and Nature news covered the result; it was not in the Sep 23 science digest, so it is included in today’s basic-research roundup.

Commentary:
The hard currency of “most accurate” is independent same-species comparison—cross-lab, cross-species checks will decide SI-second politics and geophysical uptake.
10. Nature Geoscience: dry-pebble accretion experiments show endogenous ocean-scale water (Planet formation)
Summary:
On Sep 24, University of New Mexico researchers Garai, Sharp, Olson, and Gargano reported in Nature Geoscience that melting anhydrous mafic rocks in H₂ streams generates large amounts of water vapour within hours via hydrogen reduction of iron oxide to metal, while the metal strongly sequesters phosphorus. The results support a pebble-accretion picture in which silicate pebbles traversing a hot H₂-rich atmosphere lose volatiles, reduce iron, and produce H₂O; metal transfer to the core can help explain Earth’s mantle phosphorus depletion versus Mars and a low Fe/Mg primitive mantle. Atmospheric iron reduction is cast as an endogenous water source for Earth-sized exoplanets built from pebbles.

Commentary:
This pulls “where did the water come from?” back into accretion chemistry—the lab reduction is clean; scaling to a whole planet remains a modeling fight.
11. Nature Materials: multilevel molecular weaving enables precise toluene/methylcyclohexane separation (Chemistry & materials)
Summary:
A Sep 24 Nature Materials paper presents a two-dimensional multilevel woven polymer network that moves beyond single-level woven topologies. Single-crystal X-ray analysis plus low-dose and cryogenic electron microscopy confirm the multilevel weave; in situ pressure-dependent Raman spectroscopy and theory reveal a hierarchical stress-regulation mechanism distinct from single-level counterparts. Breakthrough experiments simulating industrial separation show synergistic channels that favour precise toluene/methylcyclohexane separation. The authors argue the shift from single- to multilevel weaving is a functional leap, not merely a structural upgrade.

Commentary:
Molecular-scale “complex fabrics” finally map onto an industrial separation pain point—scalable synthesis and long-term stability are the exit tickets from the crystallography showcase.
