I. Space & Deep Space
1. ISS completes U.S. Spacewalk 100, installs seventh roll-out solar array (station operations)
Summary:
NASA confirmed late on October 29 that astronauts Anil Menon and CSA astronaut Joshua Kutryk finished U.S. Spacewalk 100 in 7 hours 11 minutes, installing and deploying the seventh IROSA on the station’s 2A power channel. Once all eight arrays are in place, available power is expected to rise from about 160 kW to roughly 215 kW (up to ~30%), supporting operations and a controlled deorbit. The crew also completed get-ahead tasks for the November 5 spacewalk that will install the eighth and final IROSA; the EVA was the 285th in support of station assembly and upgrades.

Commentary:
Power capacity is the hard constraint on ISS science and crew loads; Spacewalk 100 leaves only one array before the upgrade series closes.
2. Turkey targets 2027 for first lunar orbiter TLM-1 (lunar exploration)
Summary:
Spaceflight Now reported on October 30 that Turkish Lunar Mission 1 (TLM-1 / AYAP-1) is planned for a SpaceX Falcon 9 launch in Q2 2027, with managers aiming for an April window. The spacecraft is led by TÜBİTAK UZAY (domestic content reported above 80%) with a DeltaV hybrid propulsion system, intended for a ~100 km circular polar lunar orbit for at least several months before a controlled hard landing at end of life. It is the first of two phases under Türkiye’s Lunar Research Program; a later lander/rover mission has no launcher selected yet.

Commentary:
For emerging space powers, an orbiter-plus-hard-landing path is less about payloads than proving deep-space autonomy in navigation and propulsion.
II. Biomedicine & Health
3. Genmab: petosemtamab plus pembrolizumab meets dual Phase 3 endpoints in first-line head and neck cancer (immuno-oncology)
Summary:
On October 28 Genmab reported the first interim analysis of global Phase 3 LiGeR-HN1 (NCT06525220): EGFR/LGR5 bispecific petosemtamab plus pembrolizumab versus pembrolizumab alone in first-line PD-L1–positive recurrent/metastatic HNSCC. An independent data monitoring committee found overall survival HR 0.50 (95% CI 0.37–0.67; p<0.0001)—about a 50% reduction in risk of death—and ORR odds ratio 3.17 (95% CI 2.06–4.89; p<0.0001), regardless of HPV status. Safety was generally consistent with each agent’s known profile, with no new signals; Genmab plans regulatory engagement and a future medical-meeting presentation.

Commentary:
Halving death risk atop a PD-1 monotherapy backbone is the readout that will decide whether this bispecific can rewrite first-line HNSCC standards.
4. Gilead places partial clinical hold on two KITE-753 CAR-T trials (cell-therapy safety)
Summary:
On its October 29 Q3 earnings call, Gilead said anti-CD19/CD20 CAR-T candidate KITE-753 for DLBCL—Phase 2 second-line PALISADES-1 and Phase 3 third-line-plus PALISADES-2—is under a partial clinical hold to probe safety differences between Phase 1 and Phase 2. Kite leadership cited grade 3–4 ICANS in a small number of patients, with no deaths or grade 5 events, and said the pause was aligned with FDA. KITE-753 uses a roughly three-day rapid manufacturing process; autoimmune KITE-363 Phase 1 studies, which do not use that process, continue.

Commentary:
The trade-off between manufacturing speed and neurotoxicity windows is becoming a shared gate for next-generation dual-target CAR-T programs.
5. Japanese team first cultivates Heimdallarchaeia, closest archaeal relatives of eukaryotes (evolutionary biology)
Summary:
A JAMSTEC-led team including Hiroyuki Imachi and Masaru K. Nobu announced October 28–29 in Nature the first isolation and growth of two Heimdallarchaeia strains—among the closest known archaeal relatives of eukaryotes. Cells had simple interiors without membrane-bound organelles such as a nucleus, but complex surface protrusions mediating attachment to microbial partners needed for growth. Both strains are anaerobic; one could grow with initial low oxygen if aerobic bacteria were present. The findings support surface-mediated symbiosis preceding internal complexity and a role for oxygen-consuming partners in bridging anaerobic ancestors toward aerobic lifestyles.

Commentary:
Moving from metagenomic inference to living cultures finally gives eukaryogenesis hypotheses an experimental near-relative model.
III. Climate & Environment
6. East Antarctic ice sheet shows atmospheric stabilization even under extreme warming (ice–climate coupling)
Summary:
Kyung-Sook Yun and Axel Timmermann of IBS Center for Climate Physics published an open-access paper in Nature Climate Change on October 30. Using a coupled atmosphere–ocean–ice-sheet model for ~100,000-year simulations under varied CO₂, they find global warming beyond ~2°C above pre-industrial drives millennial-scale West Antarctic disintegration, while East Antarctica remains far more resilient even at ~10°C or more—via a moister, cloudier atmosphere and southward-shifted westerlies that boost snowfall and cut shortwave radiation. For Greenland they identify a ~6°C threshold. Capturing ocean- versus atmosphere-driven mass balance is key to long-term sea-level projections.

Commentary:
Quantified “fragile West, resilient East” thresholds matter for policy, but only as far as the long coupled simulations’ uncertainties allow.
7. NASA OCO-2/3 decade-long atmospheric CO₂ record gets an algorithm upgrade (carbon-cycle observing)
Summary:
Eos reported on October 30 that Taylor et al. compiled an improved global atmospheric CO₂ record from NASA’s Orbiting Carbon Observatory-2 and -3 spanning September 2014 to the present after algorithm updates. Improvements include better instrument calibration and treatment of clouds, aerosols, and ocean reflectance; the refreshed 2014–2026 record agrees more closely with the ground-based precision network, and the two satellites cross-check well. Finer temporal resolution aids month-by-month tracking of extreme-event impacts on the carbon cycle; the public dataset can help assess climate-policy effectiveness. The work appears in Earth and Space Science (DOI: 10.1029/2026EA005360).

Commentary:
Moving satellite carbon monitoring from annual baselines toward near-real-time monthly tracking is shared infrastructure for policy evaluation and event attribution.
8. October 2026 on track to be the hottest October on record (global temperature)
Summary:
Scientific American reported on October 30 that projections by climate scientists Andrew Dessler and Zeke Hausfather, based on Copernicus Climate Change Service (C3S) data, put this month about 1.76°C above pre-industrial levels—above the prior October record near 1.7°C in 2023—making it almost certain to be the hottest October observed and pushing 2026 among the hottest years. Hausfather warned a developing “Super El Niño” could keep setting monthly records into 2027. The piece stresses fossil-fuel emissions as the long-term driver, with El Niño as a short-term amplifier.

Commentary:
If the hottest October lands, it pulls the 1.5°C conversation from annual averages back into month-by-month lived heat.
IV. Basic Research & Instrumentation
9. University of Tokyo: mid-infrared photothermal tomography delivers ~400× faster live-cell 3D “video” (bioimaging)
Summary:
Fukushima, Ideguchi and colleagues at the University of Tokyo reported on October 30 in Nature Communications video-rate mid-infrared photothermal optical diffraction tomography (MIP-ODT). By rapidly switching illumination angles and maximizing per-shot SNR, the system reaches 19.2 volumes per second (a full 3D image every ~52 ms)—nearly 400 times faster than prior MIP tomography (~0.05 fps)—without temporal averaging. The team tracked lipid-droplet trajectories in living cells and quantified heterogeneous transport, and can acquire multi-wavenumber volumetric chemical imaging across a ~300 cm⁻¹ window in about one second.

Commentary:
Label-free chemical specificity plus sub-second volumetric rates shifts the goal from static structure to filming intracellular dynamics.
10. Penn: photonic quantum skyrmions keep topology after entanglement vanishes (quantum information)
Summary:
Penn Engineering’s Liang Feng group, with collaborators at the University of the Witwatersrand and Nanyang Technological University, highlighted on October 30 their Nature Physics work: a silicon-nitride chip prepares entangled photon pairs and transfers skyrmion topology from a local single-photon state into a shared two-photon state. Experiments show the topological invariant can survive after disruption severs entanglement, breaking only under still stronger noise, while nonclassical correlations persist as quantum discord. The authors frame this as a step toward topology-mediated quantum interconnects beyond entanglement alone.

Commentary:
If “entanglement gone, topology intact” can be engineered, quantum-network noise budgets may need rewriting.
11. Carnegie Mellon: micelle-tagging electrophoresis reads DNA up to 782 bases without gel (sequencing tech)
Summary:
Carnegie Mellon’s James Schneider team, with Thermo Fisher Scientific, described on October 30 micelle-tagging electrophoresis (MTE) published in Electrophoresis: combining nano-micelle tags and alignment algorithms to read DNA fragments up to 782 bases without gel—about 280 bases longer than prior gel-free efforts and nearly threefold versus competing free-solution methods. The aim is to bypass gel electrophoresis bottlenecks in throughput and automation for longer, more integrable electrophoretic sequencing.

Commentary:
Removing gels from the electrophoresis pipeline is a key process cut for automated, chip-scale sequencing speedups.
12. UC Davis: fluorescence-illuminated diffraction tomography sees cells and surrounding tissue together (microscopy)
Summary:
UC Davis biomedical engineer Yi Xue’s team on October 30 described fluorescence-illuminated diffraction tomography in Nature Communications, combining fluorescence’s cell specificity with phase imaging’s quantitative, label-free morphology so stained cells act as internal light sources that reveal surrounding tissue in thick samples—avoiding transmission illumination that struggles to pierce deep tissue. Computational reconstruction cut comparison runtimes from about three hours to 50 minutes while improving deep-tissue resolution at lower memory; the method was demonstrated across multiple biological samples.

Commentary:
Microscopy has long shown cells without the scene; restoring tissue context matters especially for tumor microenvironments and histopathology.
