Science turned biological extremes into tests of planetary and system resilience

Day’s Recap

Supporting Articles

Northwestern researchers found that controlled variation among components can make complex systems more stable than perfectly uniform ones. The effect appeared across models relevant to power grids, ecosystems, neural networks, and engineered materials, with some random differences also improving resilience.

A massive crater on Phobos may contain a dense layer of compressed material that can distinguish between two competing origins: a captured asteroid or debris blasted from Mars. Japan’s MMX mission is expected to return samples and measurements that could test both possibilities.

A deep-sea microbe uses an unusually heat-stable enzyme to convert atmospheric nitrogen into ammonia at temperatures that denature most proteins. Its structure and a newly observed reaction state may clarify how nitrogen fixation evolved and inform cleaner approaches to fertilizer production.

A curated list of other prominent stories from this day.

A chemical that prevents drywood termites from forming new exoskeletons killed about 95% of tested colonies. The treatment exploits molting, an unavoidable part of the insects’ life cycle, and could offer an alternative to conventional fumigation.

A single-celled organism can contract to roughly one-quarter of its length in milliseconds using a calcium-controlled protein network that behaves like a microscopic fishnet. Researchers are studying the mechanism as a possible model for fast artificial muscles.
