Space Exploration¶

8 NASA's lunar Gateway spaceport will serve as first moon airport within two decades¶

NASA is developing Gateway, a lunar spaceport located in a Near Rectilinear Halo Orbit approximately 240,000 miles from Earth that will serve as a hub for crewed Orion capsules, lunar landers, and cargo vehicles within the next two decades. Engineers have developed algorithms and operational strategies to manage spacecraft traffic and collision risk in this gravitational environment.

Gateway in Near Rectilinear Halo Orbit (NRHO): ~1,000 miles from moon's north pole, ~40,000 miles beyond south pole
Uninterrupted line-of-sight communication with Earth; minimal propellant needed to maintain orbit
Algorithms and procedures developed to coordinate multiple spacecraft and reduce collision risk
Research published in Acta Astronautica by engineers from Texas A&M, NASA Johnson Space Center, and Purdue

8 Pennsylvania Reports First Two Measles Deaths in U.S. This Year, Both Unvaccinated¶

Two unvaccinated Pennsylvania residents died from measles, marking the first US measles deaths in 2026. The nation is experiencing its worst measles year since 1991 with 2,777 cases, and the US risks losing its measles-free status in a November 2026 determination.

2,777 measles cases in 2026, worst year since 1991
Both deaths unvaccinated; from Lancaster County
Pennsylvania accounts for ~400 of national cases
Lancaster County kindergarten vaccination rate ~88%, below 95% threshold
U.S. kindergarten exemption rates at all-time high
November 2026 determination on U.S. measles-free status

7.5 Shingrix vaccine linked to 24% lower dementia risk in study¶

A study of over 509,000 older adults found that those who received Shingrix, the recombinant shingles vaccine, were 24% less likely to develop dementia over four years—approximately one case prevented per 17 vaccinated people. The analysis used Medicare claims and electronic health records from skilled nursing facility admissions between 2017 and 2022.

24% lower dementia risk in vaccinated cohort
18.8% dementia rate in vaccinated vs 24.6% in unvaccinated (509,926 adults age 66+)
One dementia case prevented per ~17 people vaccinated
Shingrix is the only shingles vaccine currently available (introduced 2017)
Study used target trial emulation to recreate randomized trial conditions from observational data

8 Gamma-Ray Signal Could Indicate WIMP Dark Matter Detection¶

Analysis of 15 years of NASA Fermi telescope data detected a halo of gamma rays extending toward the Milky Way center that closely matches theoretical predictions for WIMPs (weakly interacting massive particles). If confirmed through independent verification and ruling out alternative explanations, this may represent the first direct observational evidence of dark matter.

20 gigaelectronvolt gamma-ray signal detected
Signal matches WIMP annihilation predictions
Particles approximately 500 times proton mass
Published November 25, 2025, in Journal of Cosmology and Astroparticle Physics
Independent verification and alternative explanations remain necessary

7.5 Scientists discover evolutionary highways guiding animal chromosome evolution¶

Analysis of thousands of animal genomes reveals that chromosomal evolution follows irreversible genetic highways rather than random pathways, illuminating 600+ million years of evolutionary history.

7.5 Newton's gravity law passes largest cosmic test across galaxy clusters¶

A test using the Atacama Cosmology Telescope across galaxy clusters spanning hundreds of millions of light-years confirms that gravitational strength decreases with distance nearly exactly as predicted by Newton's inverse square law and Einstein's general relativity. The findings significantly weaken modified gravity theories and strengthen support for dark matter.

Largest-scale gravity test conducted across galaxy clusters hundreds of millions of light-years apart
Results confirm Newton's inverse square law and Einstein's general relativity predictions
Significantly weakens Modified Newtonian Dynamics (MOND) and other modified gravity theories
Strengthens case that dark matter, not modified gravity, explains cosmic motion discrepancies

7.5 AI and Advanced Monitoring Reveal Northern Spotted Owl Populations Approaching Functional Extinction¶

A study using AI and passive acoustic monitoring found that northern spotted owl populations have approached functional extinction across large areas of the Pacific Northwest, with barred owl calls detected eight times more frequently. Despite 30+ years of protection, populations continue declining due to habitat loss and barred owl competition.

Barred owl calls detected 8× more frequently than spotted owl calls
Northern spotted owls confirmed in 261 of 1,027 sampled hexagons
Study analyzed 2.1 million hours of recordings across 38,000+ sq mi
Not detected in Washington Cascades north of Seattle
Functional extinction means populations too low for ecological role or reproduction

7.5 New Process Doubles PFAS Molecule Size, Enabling Destruction of Forever Chemicals¶

Rice University researchers developed a process doubling PFAS molecule size to enable destruction of these persistent pollutants. A layered double hydroxide material captures PFAS over 1,000 times better than other materials, breaking down chemicals hundreds to thousands of times faster while remaining reusable.

Archaeology¶

7.5 Ancient ritual structure 1,000 years older than Stonehenge discovered in Czech Republic¶

Archaeologists in the Czech Republic discovered a 6,500-year-old ritual sanctuary near Chleby, predating Stonehenge by approximately 1,000 years. The site features an almost circular enclosure 230 meters across with twelve irregularly positioned entrances and two main sight lines aligned to solar and lunar cycles.

6,500 years old, ~1,000 years older than Stonehenge
Almost circular enclosure ~230 meters across surrounded by ditch >2.5 meters deep
Twelve entrances in deliberate geometric pattern, not randomly placed
Two main sight lines: one to moon's 18-year cycle extremes; one to summer solstice sunrise and winter solstice sunset
Bull skulls and horns found in ditch near entrances; ~18 people buried in ditch over time, including Bronze Age and Iron Age periods
