Military space systems are shrinking in size, and that shift is forcing difficult engineering tradeoffs in electronics design. As spacecraft get smaller, engineers must balance radiation hardening, thermal management, power constraints and performance in tighter packages, since smaller components face harsher physical conditions in orbit. Coverage highlights how these physics-driven constraints are shaping the next generation of military satellites and defense space capabilities.

A forecaster says heating will be turned on in Moscow within the next few days, as autumn cold sets in and residents await the start of the season. The news is being closely followed by residents eager to know when radiators will warm up in their homes and communal services will begin the annual switch-over.

A new article examines the black hole information paradox, explaining why quantum unitarity clashes with Hawking's thermal radiation and how the Page curve frames the problem. It also covers recent island and replica-wormhole calculations that reproduce the curve in simplified models, along with the firewall argument and the ER=EPR conjecture linking entanglement to spacetime geometry.

Mount Sinai has announced a collaborative research agreement to evaluate a novel liquid radioembolic agent for treating brain tumors. The therapy would deliver radiation directly to tumor tissue in liquid form, an approach being explored for cancers that are difficult to treat surgically. Details on the partner institution, trial design and timeline have not yet been released, and clinical results remain pending.

A newly discussed exoplanet sits within its star's habitable zone, but scientists caution it lies near the so-called cosmic shoreline. This means its host star may have stripped away the planet's atmosphere through intense radiation, leaving it unable to hold liquid water despite orbiting at a seemingly habitable distance. The case highlights how the habitable zone alone is not enough to judge a planet's prospects for life, and atmospheric loss must also be considered.

A new study reports that exposing an ocean water microbiome to controlled near-space conditions triggers a restructuring of its microbial community. The research, published via Astrobiology Web, suggests that stratospheric-level exposure — including low pressure, radiation and temperature extremes — can alter the composition of marine microbial populations. The findings may inform astrobiology research on microbial survival beyond Earth and the effects of high-altitude environments on ocean microorganisms.

Google's Project Suncatcher has put its first satellite into orbit carrying four TPU chips as an early test of computing in space. The prototype runs its TPUs for about 15 minutes at a time before needing to cool down, because a spacecraft has no air or water for cooling and must shed heat by radiation alone. Engineers point to this as a key constraint for future orbital data centers, which supporters hope could one day run at scale using solar power in orbit.

New Zealand is being discussed as a possible 'last safe place' after a nuclear war, thanks to its geographic isolation, distance from likely conflict zones, and capacity for agricultural self-sufficiency. Commenters are debating whether the country's remoteness would really shield it from radiation, climate disruption and global food-system collapse in the aftermath of a nuclear exchange.

Scientific American examines whether genetically engineered microbes could make Mars more habitable. The idea is that bacteria might be used to produce gases or nutrients that warm the planet or enrich its soil, offering a biological route to terraforming. Researchers weigh whether such organisms could survive Mars's harsh radiation, cold and thin atmosphere, or whether the concept remains speculative.

Nuclear education site Nuclear Power details how tobacco smoking exposes smokers to radiation. Tobacco leaves naturally concentrate polonium-210 and lead-210 from phosphate fertilisers and airborne particles, and inhaled during smoking these deliver a low but chronic dose of alpha radiation to lung tissue. The item is drawing attention on discussion forums, where readers are debating how significant this exposure is compared with other man-made radiation sources.

New research into tardigrades, the microscopic animals known as water bears, suggests their remarkable resilience to extreme conditions stems from stress-protective proteins that evolved independently along similar paths in different lineages. The findings point to convergent evolution in the molecular machinery that lets these creatures survive drying, freezing and radiation, offering clues for biotechnology and stress-tolerance research.

New reporting describes how space radiation may trigger a biological cascade that leads to cancer, a concern for astronauts on long missions to the Moon and Mars. High-energy particles can damage DNA and set off chain reactions in cells that promote tumour growth, underscoring the health risks of deep-space travel.

Google has reportedly placed its first orbital data center into orbit, marking a step toward computing infrastructure in space. The development was highlighted by computer scientist Daniel Lemire on his blog, filed under space and technology. Orbital data centers could offer solar-powered, always-illuminated computing, though questions remain about maintenance, cooling and radiation resilience.

A new image of the Marius Hills Pit, a volcanic shaft on the Moon's near side, has been released. The pit, first spotted in lunar orbiter data, is a collapsed lava tube opening that researchers study for clues about the Moon's volcanic history and as a potential site for future human habitation, since underground cavities could shield astronauts from radiation and extreme temperatures.

Google has launched a satellite carrying AI chips designed to test how the hardware performs in space. The experiment will assess whether chips can withstand radiation and harsh orbital conditions while processing data outside Earth. The launch, reported by international outlets including CGTN and China Daily, points to growing interest in running artificial intelligence workloads directly in orbit rather than relying entirely on ground-based data centres.

A decades-long design problem is drawing attention: how to warn people thousands of years from now about buried nuclear waste, when languages and civilizations may have vanished. Proposed solutions range from hostile architecture and eerie earthworks to atomic 'ray cats' bred to change color near radiation, with semioticians and physicists still debating whether any message can truly outlast time.

Scientists report that a deep pit on the lunar surface could be an entrance to a large underground cave beneath the Moon. Such caverns, possibly ancient lava tubes, could shield future astronauts from radiation, extreme temperatures and micrometeorites, making them candidates for future lunar bases. The finding is drawing wide attention as space agencies plan renewed crewed missions to the Moon.

The annual Draconid meteor shower is back in the spotlight, with stargazers sharing viewing guidance for the 2026 display. The shower, produced by debris from comet 21P/Giacobini-Zinner, radiates from the constellation Draco and is typically best seen in early October from the Northern Hemisphere, though it usually produces only a modest number of meteors per hour.

New radiotherapy trials are underway that could redefine how brain metastases are treated, according to Physics World. The trials are testing refinements in radiation delivery and dosing for patients whose cancer has spread to the brain, aiming to improve tumour control while reducing damage to healthy tissue and side effects. Researchers say the results could influence clinical guidelines and standard practice for a growing group of patients as cancer survival overall improves.

Astrophysicist Ethan Siegel tackles a reader question about Hawking radiation: as black holes evaporate, their event horizons shrink, raising the question of whether sufficiently small horizons could expose something other than a singularity at the core. The discussion explores what happens at the end stages of black hole evaporation and what theoretical physics predicts about these objects' final fate.

A new research paper argues that radiation-resistant engineered yeast could be used to shield habitats on Mars, addressing one of the main obstacles to long-term human settlement on the planet.
