A digest of science, space, biomedicine, and climate research for October 26, 2026, with summaries, links, and commentary.
I. Space and Deep Space
1. International Space Station: Expedition 75 rehearses the robotic arm for Thursday’s roll-out solar array installation (Spaceflight)
Summary:
NASA’s station blog on October 26 said Expedition 75 began the week preparing for a spacewalk to upgrade the station’s power system. NASA flight engineer Anil Menon and CSA astronaut Joshua Kutryk will exit the Quest airlock at 8 a.m. EDT on Thursday to install one of two roll-out solar arrays on the port truss, on a planned six-hour, 45-minute spacewalk. NASA’s Jessica Watkins and Luke Delaney will support them from inside and with Canadarm2. The four astronauts rehearsed the arm procedures on Monday, and Menon and Kutryk checked emergency jetpack fuel, batteries, and thrusters. The blog also notes that a SpaceX Dragon cargo spacecraft docked autonomously to Harmony’s space-facing port on October 15 and is due back in mid-November.

Commentary:
This is the next installation in an existing roll-out array upgrade; the spacewalk has not started, and any power gain comes only after controllers activate the new array.
2. NEO Surveyor: sunshade solar arrays are integrated, with up to about 2 kilowatts (Planetary defense)
Summary:
NASA’s Science Mission Directorate reported on October 26 that the sunshade of the Near-Earth Object Surveyor, the spacecraft’s largest structure and the shield that blocks sunlight and keeps the infrared telescope cold, now has its solar arrays integrated. The structure is 20 feet (6 meters) tall and 8 feet (2.4 meters) wide at the base, with two flat panels joined at 23.5 degrees. Earlier this year it was covered with 864 interconnected solar cells that can produce up to about 2 kilowatts to charge the onboard batteries. The telescope’s 20-inch (50-centimeter) aperture feeds two infrared detector arrays, each making a 16-megapixel image, so two bands can be used to estimate an asteroid’s or comet’s temperature and size. Applied Aerospace in California built the structure, SolAero in New Mexico installed the cells in January, thermal-vacuum testing finished in March, and the hardware reached BAE Systems in Colorado ahead of schedule in May, where coarse Sun sensors, temperature sensors, and array functional tests were then completed.

Commentary:
The update confirms ground integration and power capacity; launch timing and on-orbit detection sensitivity are not in this log.
3. ESA’s director general proposes about €10 billion over ten years for crew launch and return; Rome meets on December 15 (Space policy)
Summary:
Euronews reported on October 26 that ESA member states will hold the 2026 Intermediate Ministerial Meeting in Rome on December 15, covering low Earth orbit, the post-International Space Station period, and lunar and Mars plans. Director general Josef Aschbacher has proposed about €10 billion over about ten years for a European system that could carry astronauts to space and return them. His estimates put the cost of continuing to buy those services abroad at about €5 billion over the same period. The report states that these are projections, not funds already allocated, and that member states decide. The same article notes that on September 10 ESA awarded The Exploration Company a contract worth €760 million for the next phase of ALADDIN: €310 million for a demonstration and a further €450 million for two missions that still have to be confirmed. Current plans have the International Space Station ending operations by 2030.

Commentary:
The €10 billion figure is the director general’s proposal to member states; Rome has not voted, and no crew vehicle has been selected.
II. Biomedicine
4. MIT’s LUCID: a 24-transducer ultrasound implant spreads an MRI contrast agent farther in the mouse brain (Medical engineering)
Summary:
The MIT News Office reported on October 26 that Canan Dagdeviren’s lab published LUCID, a long-term ultrasound-enhanced convective injection device, in Device. The cardstock-thin flexible implant prints a drug cannula directly onto 24 miniature ultrasound transducers, holds about 100 microliters, infuses with an osmotic pump, sets ultrasound dose over Bluetooth, and uses a wirelessly recharged battery. A little more than 10,000 glioblastoma cases are diagnosed in the United States each year, and average survival after diagnosis is 12 to 15 months. In a tissue-mimicking gel and in mice, molecules or an MRI contrast agent spread farther when ultrasound was on than with infusion alone. Graduate student Sarah Ornellas and Jason Hou are the lead authors. Funding came from the MIT Media Lab Consortium and the National Institutes of Health. If used in patients, the cannula and array would sit inside the skull and the battery and electronics outside it.

Commentary:
The mouse comparison is how far a contrast agent spreads; the release does not give a millimeter-scale gain or any antitumor efficacy.
5. University of Pennsylvania: raising the backup protein utrophin increases force in a mouse model of Duchenne muscular dystrophy (Gene therapy)
Summary:
The Perelman School of Medicine at the University of Pennsylvania said on October 26 that Tejvir S. Khurana and colleagues report a CRISPR approach in Molecular Therapy Advances. A muscle-directed MyoAAV vector and lipid nanoparticles of the kind used for COVID mRNA vaccines deliver the editing cargo and raise utrophin, a stand-in for the dystrophin that is missing in Duchenne muscular dystrophy. The university said the disease affects roughly one in 5,000 children and typically leads to death in the patient’s twenties. Treated mouse models showed increased muscle force, better resistance to contraction, and fewer of certain diseased fibers. The experiments were designed to test prevention of progression. Khurana said that if enough nuclei in a damaged muscle cell are edited, the newly expressed protein would not in theory stay confined to those nuclei. The Muscular Dystrophy Association provided partial support. Drew Weissman and Michael Mitchell contributed the mRNA and lipid-nanoparticle delivery.

Commentary:
The university news reports the direction of change in mouse force and diseased fibers, without a fold increase for utrophin or an editing efficiency.
6. UC San Diego: marine-derived rutamycin B reaches full effect against Naegleria fowleri within four hours (Antiparasitic)
Summary:
The University of California San Diego reported on October 26 that Anjan Debnath, William Fenical, Hayley Fong, and colleagues describe rutamycin B, isolated from a marine bacterium, in Marine Drugs. At low concentrations it is active against multiple clinical strains of Naegleria fowleri. Primary amoebic meningoencephalitis has a fatality rate above 97 percent. The compound reaches full potency in about four hours, compared with 16 hours for the standard drug amphotericin B, and it is 200 to 300 times more lethal to the parasite than to human cells by shutting down an enzyme the parasite uses to make energy. Combined with standard treatment, 3 to 10 percent of the original rutamycin B dose still produced the same result. The team says the next studies will test blood-brain barrier crossing and live disease models. Partial funding is NIH R21EY034294 and R21AI171538. A PCT application was filed on March 12, 2026, number PCT/US26/18919.
Links:
Commentary:
The four-hour timing and the 200- to 300-fold selectivity are in vitro; the release is explicit that live efficacy is still ahead.
7. Nature Neuroscience: microglial NUS1 loss sends iron into dopaminergic neurons through LCN2–SLC22A17 (Parkinson’s)
Summary:
Nature Neuroscience on October 26 published a paper from Haigang Ren and Guanghui Wang at Soochow University’s College of Pharmaceutical Sciences, with Jifeng Guo and Beisha Tang at Xiangya Hospital of Central South University, and colleagues. NUS1 encodes NgBR, which is highly expressed in microglia. In mice, microglial NgBR deficiency produces progressive Parkinson’s-like motor deficits and dopaminergic neuron loss through the LCN2–SLC22A17 iron-transport axis. In mouse and human microglia, NgBR loss triggers endoplasmic reticulum stress and PERK–ATF4–NUPR1 signaling, which preferentially increases LCN2-mediated iron efflux rather than classical cytokines. Only iron-loaded Holo-LCN2, not iron-free Apo-LCN2, is taken up by SLC22A17 on dopaminergic neurons, leading to iron overload and ferroptosis. Inhibiting this axis or ferroptosis reduced neuron loss and motor symptoms in vitro and in Nus1 conditional-knockout mice. Funding includes National Natural Science Foundation of China grants 32471047, 32170987, 32271039, and 82271281.

Commentary:
The therapeutic implication in the paper is pharmacological inhibition of this iron-transport axis; the abstract does not report dosing in people.
8. Paradromics: the FDA clears removal of the four-hour travel limit in the Connexus early feasibility study (Brain-computer interface)
Summary:
Paradromics said on October 26 that the U.S. FDA approved a protocol amendment for its Connect-One early feasibility study, dropping the requirement that participants live within a four-hour drive of a clinical site. Connexus is a fully implantable wireless brain-computer interface that records single neurons and turns intended speech into digital communication. The company said human trials began this year, the first long-term implant was completed at University of Michigan Health in June 2026, and the first participant is communicating independently with synthesized speech, text messages, and phone calls. Participants must still be able to travel to a study site for required activities. Sites include UC Davis Health, with lead principal investigator David M. Brandman; Mass General Brigham, with Daniel B. Rubin; and University of Michigan Health, with Matthew Willsey. The study received an investigational device exemption in November 2025 and is assessing long-term safety and performance in severe motor impairment, with communication as the first clinical focus.

Commentary:
The clearance widens where people may be recruited; it is not an efficacy result, and the company release does not give a speech-recognition rate or an adverse-event count.
III. Climate and Environment
9. An ancient Baffin Bay ice shelf about 1,400 to 2,100 meters thick and about 150,000 square kilometers across, followed by rapid ice-sheet retreat (Cryosphere)
Summary:
Nature Geoscience on October 21 published a paper by Shannon Klotsko of the University of North Carolina Wilmington, Robert Hatfield of the University of Florida, and Brendan Reilly, Jacqueline Austermann, and Lauren Lewright of Columbia University’s Lamont-Doherty Earth Observatory, with colleagues. The Columbia Climate School reported the work on October 26. Global ice volume peaked about 26,500 to 19,000 years ago, when the Laurentide, Innuitian, and Greenland ice sheets met in Baffin Bay. Seafloor landforms indicate a basin-spanning ice shelf about 1,400 to 2,100 meters thick after a relative-sea-level correction, covering about 150,000 square kilometers and buttressing the three ice sheets. Sediment cores are used to infer that ice-shelf collapse triggered rapid ice-sheet retreat. Columbia’s account says the shelf disappeared over about 500 to 1,000 years, with the exact timing still uncertain. Hatfield said the evidence was at least half a mile thicker than any previously known Northern Hemisphere ice shelf.

- Columbia Climate School — How a massive ancient ice shelf stabilized glaciers, and what it means for Antarctica
Commentary:
The present-day point is an analogy: an ice shelf can disappear over centuries and reorganize marine ice sheets. The paper does not supply a future Antarctic sea-level number.
10. New Scientist: satellite heat flux is used to infer a 14 percent weakening of the AMOC over 30 years (Ocean climate)
Summary:
New Scientist reported on October 26 an analysis by Richard Allan of the University of Reading and colleagues. Heat flux out of the North Atlantic into the atmosphere fell 18 percent over 40 years, and from that the authors infer that the Atlantic Meridional Overturning Circulation weakened 14 percent over 30 years. The method combines the satellite energy imbalance with reanalyses and models to estimate heat leaving the ocean. The article says the paper is still under peer review, with a preprint on Research Square. For context it cites about a 10 percent decline since 2004 in Atlantic buoy measurements, and notes that the current can ebb for decades. Stefan Rahmstorf of the University of Potsdam argues that heat flux is not necessarily a better indicator than directly measured sea-surface temperature, while several lines of evidence point to a slowing circulation. A separate UK program of £81 million aims to build an early-warning system for collapse by 2030; this study is not part of it.
Links:
- New Scientist — Satellites show some of the strongest evidence the AMOC is weakening
- Research Square — Evidence the ocean is losing less heat in the northern Atlantic and the AMOC has started to slowly weaken
Commentary:
The 14 percent figure is inferred from heat flux and has not finished peer review, so it should not be treated as the same number independently confirmed by the buoy record.
IV. Basic Research
11. University of Oxford: continuous mass photometry follows single biomolecules for about an hour, with sub-kilodalton mass precision (Biophysics)
Summary:
Nature Methods on October 26 published an open-access brief communication by Dan Loewenthal, Roi Asor, and Philipp Kukura of the University of Oxford, with colleagues. Continuous mass photometry tethers biomolecules to supported lipid bilayers and records the molecules, their complexes, and their interactions for about an hour with mass resolution, at up to sub-kilodalton mass precision and millisecond time resolution. On commercial instruments with 488- and 520-nanometer light, molecules often became stuck within tens of seconds. With 638-nanometer illumination on a custom instrument, individual proteins could often be followed for up to an hour, at the cost of weaker optical contrast. The paper says the method can currently track dynamics reliably when the starting mass is above 200 kilodaltons, the mass change is above 20 kilodaltons, and lifetimes run from seconds to tens of minutes. Raw data and code are in the Oxford Research Archive.

Commentary:
Sub-kilodalton precision is the method’s ceiling; the reliable window still requires molecules above 200 kilodaltons and mass steps above 20 kilodaltons.
12. Leiden University: FUS protein fibers grow outward from the droplet surface, and the glassy state competes with the fiber state (Soft matter)
Summary:
Leiden University on October 26 described work by Liru Feng, Louise Jawerth, and Frank Jülicher of the Max Planck Institute for the Physics of Complex Systems, with colleagues, published in Nature Physics. The journal page lists October 20 as the publication date. The model protein is FUS, which is linked to neurodegenerative disease. Droplets are about 5 micrometers across. Twelve hours of three-dimensional confocal imaging showed fibers growing mainly from the droplet surface out into the dilute phase, while the droplets shrank and became glass-like solids. When proteins were aged for two days before fiber growth was started, the aged droplets hardly grew fibers. Fibers and the glassy state are two solid forms of the same protein: they can coexist, and they do not directly turn into each other. Data and code are on Zenodo (10.5281/zenodo.20558827).

- Leiden University via Phys.org — Physicists reveal a new paradigm for fiber growth in neurodegenerative diseases
Commentary:
This is a competition between material states in purified FUS droplets. Jawerth said in the report that these fibers are not yet shown to be the main reason brain cells degenerate.
Today's Summary
- Space: Expedition 75 rehearsed the robotic arm for Thursday’s installation of one roll-out solar array. The NEO Surveyor sunshade solar array can produce up to about 2 kilowatts. ESA’s director general has framed a European crew launch-and-return system as about €10 billion over ten years, with the Rome meeting on December 15.
- Biomedicine: LUCID used a 24-transducer ultrasound implant to widen infusion in the mouse brain. Utrophin gene editing improved force in a Duchenne mouse model. Rutamycin B killed Naegleria fowleri in vitro within four hours. A Soochow University team reports that microglia send iron into dopaminergic neurons through LCN2.
- Climate: An ancient Baffin Bay ice shelf about 1,400 to 2,100 meters thick is tied to rapid ice-sheet retreat after collapse. A satellite heat-flux preprint reads the Atlantic overturning circulation as 14 percent weaker over 30 years, and that manuscript is still under review.
- Basic research: Oxford’s continuous mass photometry extends single-molecule mass trajectories to about an hour. Leiden’s FUS experiments show fibers growing outside the droplet, with a glassy state competing with the fiber state.
Daily Framing:
October 26 was an engineering-milestone and mechanism-paper day: station power, a near-Earth-object telescope sunshade, and a European crew proposal all moved forward, while journals turned Parkinson’s iron transport, single-molecule mass, and protein-droplet aging into testable mechanisms.
