generator (RTG) that has been delivering electricity since the probe’s launch in 1977. Over time the RTG’s heat source diminishes, forcing engineers to prioritize which subsystems stay powered. To address the dwindling energy budget, NASA’s team has...

emphasized that the fort’s primary purpose was to safeguard water, a critical asset in a landscape where any permanent source attracts raiders. Reinterpreting the legend of Ubar Whether the expedition “found Ubar” hinges on the original meaning of the...

milky sea near Socotra in the Arabian Sea retrieved water containing Vibrio harveyi, a bacterium later hypothesized as the source. Unlike planktonic flashes that appear briefly when disturbed, these bacteria can maintain illumination for days or weeks,...

are shown in the top panels, while the bottom panels show imaging obtained on 2026 March 25 (T0 + 3.6 days). A blue point source (g − i ≈ −1.3 mag) is visible at the location of the transient in archival imaging (see Appendix C). The transient explosion...

Interplanetary Society, outlines a suite of colossal engineering strategies that could keep Earth viable by exploiting resources already present in the solar system. Megastructural Sunshade to Temper a Growing Star To counter the intensifying heat of a...

in inflow can translate into extensive surface retreat. Lake Poopó—once Bolivia’s second‑largest lake and a vital fishing resource—has essentially dried up. Credit: NASA The basin has experienced previous dry spells, notably in 1994, when water receded...

between 8.1 mg and 11.2 mg of myoglobin per gram of dry weight. The authors argue that plant cultivation demands fewer resources than livestock farming, suggesting that chloroplast‑derived myoglobin could achieve competitive yields per hectare while...

in extreme cold environments, including habitats in Antarctica, suggesting that the glacier itself may have been the source. While some DNA fragments were highly degraded, others remained remarkably intact, raising the possibility that certain microbes...

evidence on Mars, revealing secrets missed in the original measurements. NASA’s Spirit rover has not revealed a fresh water source on the Red Planet. Instead, a fresh look at two‑decade‑old data shows that mineral signatures tied to water were already...

Mantzourani. Using portable X‑ray fluorescence (XRF), the team conducted non‑destructive compositional scans on objects sourced from 33 archaeological sites. Ring Artifacts Reveal Nickel‑Rich Iron Only the ring‑type objects displayed measurable nickel...

Geochimica et Cosmochimica Acta, also uncovers a distinctive neodymium isotope pattern that points to a deep‑seated Martian source preserving the early solar system’s signature. Filling a Vast Temporal Void in Martian Igneous History Because no rover...

a series of plausible yet unproven explanations. The Foreign Technology Division concluded without identifying a definitive source or function for the phenomenon.

Durability emerged as a key issue for photoluminescent coatings in hot, humid environments. A 2021 study cited in the source material observed that such coatings degrade more rapidly under tropical conditions, with performance dropping enough to...

on the island. The authors therefore conclude that the animals’ modest size primarily reflects the dimensions of their source populations rather than an adaptive response to insular conditions. Genomic Footprints of Feralization Beyond body size, the...

a Major Gap in Mars’ Sedimentary History NASA researchers describe the target as a candidate “erosional supersurface” [source]. In geological terms, such a surface marks a shift from a period of sediment accumulation to one of erosion, followed by a...

implementation for protein‑language modeling presented at ICML 2024. At the time of the Windows 98 demonstration, no open‑source large‑scale BitNet model was publicly available, and the team planned a full‑size training run in 2025. Byte‑Level Models...

ammonium. These microbes form thick mats on rock walls, submerged surfaces, and the cave floor, providing the primary food source for a suite of higher‑order organisms. Because the environment is completely dark, the usual photosynthetic pathways are...

the researchers were able to attribute the observed emission to three separate black holes rather than a single, blended source. “It suggests that processes in the early universe were efficient at bringing massive black holes together, setting the stage...

Distinct Contributions From In‑Core Fuel and Spent‑Fuel Pools The residual antineutrino signal does not arise from a single source. Fuel assemblies that remain inside the shut‑down reactors dominate the first hours after shutdown, when relatively...

environment needed for corundum formation. Alternative formation pathways cannot be ruled out, and the original source bedrock for the float rocks has yet to be located. Identifying the parent outcrop would allow scientists to place the mineral...
