Scientists have identified remarkable adaptations in snow flies that allow them to remain active in subzero conditions. According to the report, these insects produce antifreeze proteins that prevent ice formation within their bodies and can generate their own internal heat. They also possess unusually unique genes and experience reduced cold-related pain compared to other insects. These traits together enable activity in environments that would freeze most species. The findings come from a ScienceDaily article (https://www.sciencedaily.com/releases/2026/03/260326011455.htm) summarizing scientific research. However, the article provides no information on study methodology, such as how heat generation or protein function was measured, the sample size of insects studied, or any limitations of the work. It appears to reference peer-reviewed work rather than a preprint, but no journal or original paper details are included in the release.
