- Nuclear regulators want to eliminate a foundational safety principal that seeks to keep radiation exposure ‘as low as reasonably achievable’
The Nuclear Regulatory Commission (NRC) is proposing to eliminate the ALARA principle, which has guided radiation safety for 50 years by minimizing exposure. The NRC aims to replace it with a 'graded approach' tied to potential radiation doses, aligning with efforts to expand nuclear energy production under President Trump. The NRC claims safety standards remain unchanged, focusing on clarifying requirements.
- SpaceX wants to build AI data centers in space. Will it work?
SpaceX aims to build AI data centers in space to meet growing computing demands driven by AI. These orbital facilities could leverage abundant solar energy and avoid Earth's environmental challenges but face hurdles like cooling, maintenance, radiation, and orbital debris.
- MIT scientists discover amino acid that helps the gut heal itself
MIT scientists have identified cysteine, an amino acid found in common foods, as a key trigger for intestinal repair in mice. The discovery showed that a cysteine-rich diet activated immune cells that promoted stem cell healing of damaged intestinal tissue after radiation exposure. This finding could lead to new dietary therapies for cancer patients experiencing treatment-related gut damage.
- What would happen if the Chernobyl disaster happened in Britain? Terrifying map reveals the huge blast radius of nuclear plants in the UK - leaving millions of Brits exposed to toxic radiation
The article explores a hypothetical scenario where a Chernobyl-like nuclear disaster occurs in the UK, highlighting a map showing the potential blast radius of UK nuclear plants and the risk of millions being exposed to toxic radiation.
