Radiator

Semiconductor Engineering reports that chips operating in extreme environments — such as space, deep-sea, automotive and industrial settings — face conditions that push them to their reliability limits. The article examines how heat, radiation and mechanical stress affect chip design and packaging, and what engineers are doing to make semiconductors survive where failure is not an option.

An alternative health influencer says he has been drinking water from a radioactive jug for 250 straight days, referencing the Revigator, a radioactive water jar sold as a health device in the early 20th century. Health commentators are highlighting the story as an example of misinformation spreading in wellness circles and its potential radiation risks.

Military space systems are shrinking, and that is forcing difficult electronics tradeoffs. Engineers must pack more capability into smaller spacecraft while contending with harsher physics: radiation exposure, thermal management and power constraints all become harder to solve as platforms get smaller. The piece examines how these competing demands are shaping the design of next-generation defense satellites and the components that go into them.

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.

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.

GE HealthCare is showcasing its photon-counting CT technology, a next-generation imaging approach that measures individual X-ray photons for sharper images at potentially lower radiation doses. The company's work in this area places it among the major imaging firms racing to bring the technology into routine clinical use, drawing attention from healthcare industry observers.

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.

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.
