I. Space & Deep Space
1. NASA and SpaceX open Crew-13 Flight Readiness Review ahead of a no-earlier-than Oct. 1 launch (Crewed spaceflight)
Summary:
On Sep 25, NASA convened the Crew-13 Flight Readiness Review at Kennedy Space Center with SpaceX and international partners to certify readiness of the crew transportation system, the space station, and partner support. The crew is NASA astronauts Jessica Watkins (commander) and Luke Delaney (pilot), CSA astronaut Joshua Kutryk, and Roscosmos cosmonaut Sergey Teteryatnikov (mission specialists), bound for a long-duration science stay as members of Expedition 75.

Commentary:
A cleared review is not a locked launch date—weather, vehicle, and docking windows can still rewrite the “no earlier than Oct. 1” plan.
2. Cygnus XL burns raise ISS altitude to set phasing for Crew-13 (Cargo logistics)
Summary:
NASA reported on Sep 25 that Northrop Grumman’s Cygnus XL (CRS-24) fired thrusters for about 18 minutes, raising apogee by roughly 1.5 miles and perigee by about 0.8 miles to an orbit of about 265.5 × 256.8 miles. The freighter arrived April 13 with more than 11,000 pounds of science and supplies and is due to depart in October with disposal cargo. The reboost supports phasing for Crew-13’s upcoming arrival.

Commentary:
Using a berthed freighter as an orbital tug is now ISS routine—Crew-13’s timeline and Cygnus’s departure share the same phasing ledger.
3. Roman Space Telescope ground stations pass high-rate downlink tests for ~1.4 TB/day (Astrophysics infrastructure)
Summary:
NASA confirmed on Sep 25 that all ground stations supporting the Nancy Grace Roman Space Telescope can receive the mission’s high data volume once science operations begin by early 2027. NASA’s Near Space Network in New Mexico, ESA’s station in Australia, and JAXA’s deep-space station in Japan will take science data at rates up to about 500 Mbps from roughly a million miles away; tests showed readiness for about 1.4 TB of daily downlink—the highest rate of any NASA astrophysics mission to date.

Commentary:
The pipeline is being accepted before science starts—the international ground network is the hard constraint on Roman’s terabyte-class daily yield.
4. ESA’s Juice sets up for a Sep 28 Earth gravity assist en route to Jupiter (Deep-space cruise)
Summary:
ESA says Juice will fly within about 8,640 km of Earth on Sep 28, 2026 (closest approach over the Indian Ocean at about 11:45 UTC), deflecting its path by roughly 20° and adding about 3.5 km/s relative to the Sun ahead of a final Earth flyby in January 2029 and Jupiter arrival in July 2031. Roughly 8.5 hours of Earth shadow before closest approach will force battery-only operations; all 10 science instruments are planned to gather Earth and Moon data from Sep 23 to Oct 3 and to rehearse optical navigation for icy-moon flybys.

Commentary:
The third Earth assist is a dual test of trajectory and battery management—shadow-period priorities will decide how much calibration science this “homecoming” returns.
II. Biomedicine & Health
5. MSK: senescence-directed nanoparticles ease tumor scarring and restore immunotherapy response in mice (Cancer immunotherapy)
Summary:
Memorial Sloan Kettering researchers report in Science that drug-loaded nanoparticles directed at P-selectin can selectively eliminate a subset of P-selectin–positive senescent macrophages that drive fibrosis and immune exclusion around liver and lung tumors. In mouse fibrosis and fibrotic cancer models, scar tissue eased and immune exclusion fell, allowing checkpoint inhibitors to shrink previously resistant tumors; key findings were corroborated in MSK lung-cancer samples and human datasets. Clinical efficacy is unproven, though toxicity was lower than with untargeted drugs.

Commentary:
Treating tumor scar as a removable microenvironment module is a concrete path to broaden immunotherapy—target specificity and long-term toxicity remain the clinical gate.
6. FDA clears Prime Medicine’s PM647 IND for in vivo prime editing in alpha-1 antitrypsin deficiency (Gene editing)
Summary:
Prime Medicine announced on Sep 24 that the U.S. FDA cleared an IND for PM647, an investigational one-time intravenous in vivo prime editor for alpha-1 antitrypsin deficiency, enabling a global open-label, single-arm Phase 1/2 trial in the United States. PM647 is designed to correct the SERPINA1 E342K (PiZ) mutation carried by roughly 100,000 people with the PiZZ genotype in the U.S.; the study will first enroll adults with lung-only disease, later expanding to significant liver involvement. Safety and tolerability come first, with initial human data expected in 2027.

Commentary:
First-in-human prime editing for AATD is a platform milestone—editing efficiency, off-target risk, and dual lung–liver benefit await 2027 readouts.
7. 103 bat genomes plus fossils rewrite the tree: powered flight may have arisen in late Paleocene Europe (Evolutionary biology)
Summary:
Reuters and The Japan Times reported Sep 24–25 on a Nature study integrating chromosome-level long-read genomes from 103 bat species (42 newly assembled) across all 21 families with 44 pre-Quaternary fossils and hundreds of morphological characters. Analyses indicate bats—and thus powered flight—likely originated in Europe about 65 million years ago in the late Paleocene, not in North America, Asia, or Africa as often hypothesized; laryngeal echolocation appears to predate crown-bat diversification. More than 1,500 bat species live today.

Commentary:
A European-origin story rewrites biogeography textbooks—the lasting asset is an all-family genomic resource for comparative immunity and longevity research.
III. Climate, Energy & Environment
8. University of Toledo: lead-free 2D/3D tin perovskite cell hits 16.19% with claimed air-stability record (PV materials)
Summary:
U.S. researchers including the University of Toledo report in Nature Materials a lead-free tin 2D/3D perovskite solar cell using the chlorinated spacer 4ClPEAI, reaching 16.19% power-conversion efficiency and lifting average efficiency across 14 devices from 10.34% (control) to 15.88%. Devices retained about 95% of initial efficiency after more than 1,600 hours in dry air and about 80% after 1,000 hours under continuous one-sun illumination at 55°C. The team calls them among the most air-stable tin perovskites of their kind to date.

Commentary:
Lead-free routes have long been squeezed by oxygen/moisture sensitivity and efficiency—16%-class performance only matters if it scales beyond lab cells.
9. Nanjing University modeling: Gobi solar farms may cut dust; 2060 rollout could lower North China spring PM by ~14% (Air-quality co-benefit)
Summary:
A Geophysical Research Letters study highlighted by Phys.org estimates that existing Gobi Desert solar arrays can slow near-surface winds and stabilize soil, cutting spring dust emissions by about 352,400 metric tons per month and downwind transport into northern China by about 131,400 tons per month. Under a China 2060 carbon-neutrality expansion to roughly 11× today’s Gobi solar footprint, the model suggests ~12% lower dust emissions, ~21% less transport, and ~14% lower average springtime PM10 across northern China; without added farms, climate-driven winds could raise emissions and transport by about 13% and 27%.

Commentary:
Casting PV as dust-mitigation infrastructure is a policy bonus—but model extrapolations hinge on siting, density, and surface management, not a substitute for field monitoring.
10. Vanderbilt–Maryland: chlorine unlocks a third-electron sulfur reaction, pushing experimental Li–S beyond 1,700 Wh/kg-S (Battery chemistry)
Summary:
Interesting Engineering reported on Sep 25 that Vanderbilt and University of Maryland researchers, publishing in Nature Energy, used chlorine to let sulfur exchange a third electron in lithium–sulfur cells. Lab tests raised sulfur charge-storage capacity by about 58% and average voltage from roughly 2.05 V to 2.54 V, enabling more than 1,700 Wh per kilogram of sulfur; a single-layer pouch cell kept about 78% capacity after 100 cycles. Stack-level specific energy is estimated near 477 Wh/kg—about 37% above the study’s conventional Li–S comparator. The work remains early-stage.
Links:
Commentary:
A third-electron voltage boost is elegant chemistry—cycle life, electrolyte compatibility, and cost will decide whether it leaves the pouch-cell prototype stage.
IV. Fundamental Research & Quantum Science
11. Quantinuum H2: braiding plus fusion of non-Abelian anyons yields a universal gate set in experiment (Quantum computing)
Summary:
Teams from the University of Chicago, Harvard, Stony Brook, and Quantinuum report in Nature creating S3-symmetry non-Abelian anyons on Quantinuum’s H2 trapped-ion processor with 54 entangled qubits, then combining braiding and fusion to demonstrate operations that in principle cover any quantum gate—capabilities braiding alone cannot provide. Authors call it the first experimental evidence that this approach can support universal quantum computing and may ease costly magic-state distillation in standard error-correction schemes.
Links:
Commentary:
A dark-horse error-correction path moving from theory onto hardware is a milestone, not a usable machine—scalable, low-overhead anyon control remains the next barrier.
12. Institut Pasteur: ArmA enzyme cracks a 50-year mystery of archaeal peptidoglycan structure (Microbiology)
Summary:
An Institut Pasteur–led team reports in Nature the identification of ArmA from the gut methanogen Methanobrevibacter smithii as the first glycosyl hydrolase specific for archaeal peptidoglycan (pseudomurein), with dual activity that cleaves both glycosidic linkages and peptide crosslinks and is required to complete cytokinesis. Digestion reveals a glycan backbone containing the previously undescribed sugar N-acetylarmosamine with alternating β(1,4) and β(1,3) linkages, overturning a structural model dating to the 1970s; ArmA homologues appear restricted to peptidoglycan-bearing methanogens.

Commentary:
A molecular can-opener rewrites the third domain’s cell-wall textbook—and finally gives methanogen ecology and biotech a dedicated enzymatic handle.
13. Nebraska team confirms intrinsic antiferroelectricity in hafnia down to the 2D limit (Condensed matter / electronics)
Summary:
University of Nebraska–Lincoln researchers Xu, Gruverman, and Tsymbal show in Science that hafnium oxide (hafnia)—already widely used in electronics—is intrinsically antiferroelectric: neighboring polar layers cancel until an applied field aligns them, with the hallmark double hysteresis, antiparallel sublattices, and interphase boundaries, persisting down to the 2D limit. Unlike many lead-bearing antiferroelectrics, hafnia is lead-free and heat-tolerant, with potential for energy storage and information devices.
Links:
Commentary:
Reclassifying a mass-production dielectric as an intrinsic antiferroelectric shortens the materials-import path—device fatigue and thin-film process windows still need engineering proof.
