I. Space & Deep Space
1. NASA selects Blue Origin for Mars Telecommunications Network, up to ~$700 million (spaceflight)
Summary:
NASA announced on Sept. 1 that it has awarded Blue Origin a firm-fixed-price contract to develop the Mars Telecommunications Network, with a maximum potential value of about $700 million, requiring delivery of a high-performance Mars telecommunications orbiter to NASA no later than Dec. 31, 2028, and expected operations at Mars by around 2030. Blue Origin will design, develop, integrate, launch, and operate the network under NASA’s Space Communications and Navigation (SCaN) program; the orbiter is to relay science data, imagery, navigation information, and critical mission communications for spacecraft on and around Mars. Industry coverage notes Congress previously appropriated roughly $700 million for this competitively bid fixed-price commercial procurement.

Commentary:
Deep-space science is shifting from “can we get there” to “will the bandwidth hold”—turning relay capacity into deliverable commercial infrastructure is a prerequisite for sample return and later crewed windows.
2. Meir and Adenot complete U.S. Spacewalk 99 outside the ISS (spaceflight)
Summary:
ESA reported on Sept. 2 that NASA astronaut Jessica Meir and ESA astronaut Sophie Adenot successfully ended U.S. EVA-99 at 21:29 CEST on Sept. 1 after 6 hours 49 minutes. Tasks included replacing a failed retroreflector on Harmony’s forward port for rendezvous and docking navigation, swapping a high-definition truss camera, preparing the Alpha Magnetic Spectrometer for a future upgrade, installing power and thermal jumpers, and collecting swabs for NASA’s MicroOrganisms experiment. It was Adenot’s third spacewalk (the 33rd by a European astronaut) and the 284th EVA supporting station assembly, maintenance, and upgrades; across three EVAs in 15 days, Adenot has logged 19 hours 42 minutes outside.

Commentary:
The value of an EVA is written in its hardware list—navigation aids, cameras, AMS prep, and microbial sampling all keep station science and traffic running.
II. Biomedicine
3. Harvard team finds mammalian genes can form chimeric mRNAs encoding functional new proteins (molecular biology)
Summary:
Coverage dated Sept. 2 reports that Ruaidhrí Jackson’s group at Harvard Medical School published in Nature (DOI: 10.1038/s41586-026-10982-x) that instructions from different genes—even on different chromosomes—can combine after chromosomal looping brings distant loci together. Using direct RNA sequencing, the team catalogued more than 30,000 chimeric mRNAs observed at least once in mammalian cells—a “dark genome” library—profiling nearly 400 regulated by inflammatory signals and conserved in human and mouse immune cells. Functional work centered on a mouse GSDMD–TMEM106A chimera that rises during infection, promotes inflammasome-mediated IL-1β release, and is necessary and sufficient for bacterial defense in gene-editing and lipid-nanoparticle delivery experiments. The authors argue the finding expands the known genome and proteome and may touch cancer, inflammation, and neurodegeneration.

Commentary:
The textbook “one gene, one protein” rule just gained a crack—drug-target maps may have been missing an entire layer of natural chimeric proteins.
4. Bacterial peptide corisin shown to drive pulmonary fibrosis; neutralizing antibody blunts damage (pulmonology)
Summary:
Researchers at the University of Illinois Urbana-Champaign and Mie University report in Nature Communications (DOI: 10.1038/s41467-026-76162-7) that the bacterial protein fragment corisin enters lung epithelial cells, accumulates in mitochondria, and disrupts proteostasis, triggering oxidative stress, premature aging, cell death, and scarring. Corisin-related bacterial DNA was detected in lavage fluid from pulmonary fibrosis patients; removing corisin with an antibody largely abolished the fluid’s lethal effects on healthy cells. Mice engineered to produce corisin continuously in the lungs developed spontaneous fibrosis, while a corisin-binding antibody reduced fibrosis severity and improved survival. The authors frame neutralization as a proof-of-concept therapeutic strategy, with a patent pending and clinical translation still ahead.

Commentary:
Turning an associated bacterial peptide into a causal driver gives fibrosis drug design a neutralize-able source target it previously lacked.
5. GSK dual-antigen mRNA flu vaccine headed to Phase III after stronger Phase II immunogenicity (vaccines)
Summary:
After presenting Flu-028 Phase II data at OPTIONS XIII, GSK said it will advance FLUm3HA.b-3NA into a Phase III efficacy trial planned to start in September 2026. The randomized, observer-blind Phase II study enrolled 971 adults aged 18 and older; the optimized B-strain hemagglutinin (HA) candidate elicited robust HA- and neuraminidase (NA)–directed responses to influenza A and B, exceeding licensed standard-dose and high-dose inactivated comparators in younger and older adults respectively, with acceptable reactogenicity and safety. The FDA granted Fast Track in July 2026; GSK describes the upcoming trial as the first Phase III for an mRNA flu vaccine intentionally targeting both HA and NA. The candidate remains unapproved worldwide.

Commentary:
Flu shots have long chased HA while underweighting NA—whether dual-antigen mRNA converts immunogenicity gains into real-world protection is the Phase III question now opening.
6. Chia Tai Tianqing bispecific ADC TQB2102 hits Phase III endpoint in HER2-low breast cancer (oncology)
Summary:
On Sept. 2, China Biopharmaceutical’s Chia Tai Tianqing said its investigational bispecific antibody–drug conjugate TQB2102 for HER2-low recurrent/metastatic breast cancer met its Phase III primary endpoint per an independent data monitoring committee. Versus investigator-choice chemotherapy, TQB2102 significantly reduced the risk of disease progression or death, with statistically and clinically meaningful PFS gains. The company said China’s Center for Drug Evaluation has agreed in writing that it may soon file a marketing application for the indication, calling it the first success of its kind to complete Phase III globally. Additional Phase III programs span front-line HER2-positive breast cancer, biliary tract cancer, and colorectal cancer.

Commentary:
HER2-low patients have long sat between sparse targeted options and toxic chemo—if approved, a bispecific ADC would push precision typing one step further into that gap.
III. Climate, Energy & Materials
7. KIER perovskite–CIGS tandem sets 26.7% small-area world-record efficiency (photovoltaics)
Summary:
According to pv magazine on Sept. 2, the Korea Institute of Energy Research (KIER) reports a 26.7% power-conversion efficiency for a perovskite-on-CIGS tandem cell, confirmed by Germany’s Fraunhofer ISE and listed on the U.S. Department of Energy–affiliated Best Research-Cell Efficiency Chart for devices under 1 cm². The team cites interface materials and processing that limit perovskite damage, plus optimized transparent electrodes and charge-transport layers to cut parasitic absorption; in-house lab efficiency was about 27%. The prior small-area perovskite–CIGS record was 26.3% from KIST in July 2025; for devices larger than 1 cm², HZB’s 25.5% still stands.

Commentary:
Tandem records are not won on the third decimal place alone—thin-film processes must also hold efficiency while staying flexible and manufacturable at scale.
8. Chlorinated organic cation yields 16.2%-efficient tin iodide perovskite cells stable >1,000 h at 55°C (materials)
Summary:
Nature Materials (DOI: 10.1038/s41563-026-02726-z; version of record Sept. 1, 2026) reports work from the University of Wisconsin–Madison, the National Laboratory of the Rockies, and partners using 4-chloro-phenethylammonium (4ClPEA) to build ultrastable 2D and quasi-2D tin halide perovskites. Stronger π-stacking and tighter interlayer packing impede oxygen and water diffusion, enabling months of bright photoluminescence in ambient air. Adding 4ClPEA improves 2D/3D film crystallinity and orientation, delivering 16.2%-efficient tin perovskite solar cells with prolonged storage stability and >1,000 hours of operational stability at 55°C—addressing the air sensitivity that has long limited lead-free tin perovskites despite their narrower bandgaps.

Commentary:
Lead-free routes win only if they win on stability first—rewriting air sensitivity as a cation-design problem is what opens a practical window.
IV. Instrumentation & Astronomy
9. Beijing Institute of Technology reports on-chip spectral computing for real-time hyperspectral cameras in Science (optics)
Summary:
CCTV and IT Home reported on Sept. 2 that a Beijing Institute of Technology team led by Liheng Bian published in Science (DOI: 10.1126/science.aef8268) an on-chip spectral computing method that integrates hyperspectral image capture through information parsing on a single chip, enabling portable real-time analysis that previously needed large servers. After shrinking the capture optics to chip scale in 2024, the new work mines spectral data correlations and redesigns compute units so data streams finish inside a dedicated chip without repeated server round-trips. The authors note that once computation is chip-based, remote-sensing satellites could produce results on orbit without downlinking raw cubes for ground processing.

Commentary:
Hyperspectral systems often capture more than they can compute—moving parsing onto the chip is what makes satellite and field detection truly real-time.
10. New model treats lunar regolith as a time capsule of nearby supernovae (astronomy)
Summary:
Space.com reported on Sept. 2 that a new computer model can disentangle supernova dust mixed into lunar dirt, opening the Moon’s surface as an archive of nearby explosions as the solar system orbits the galaxy. Radioisotopes in deep-sea sediments and Apollo regolith already point to supernova activity peaks about 2.3 and 7.3 million years ago, but Earth’s erosion and tectonics leave reliable terrestrial records extending only roughly 10 million years; the airless, tectonically quiet Moon may preserve signals for 80–100 million years or longer. The model reproduces iron-60 depth–concentration profiles in Apollo samples and frames burial patterns for plutonium-244, iodine-129, hafnium-182, and curium-247.

Commentary:
The Moon is more than a geologic sample library—on deep-time scales it may also back up the supernova chronicle Earth has largely erased.
