• On March 10, the University of Houston announced researchers at its Texas Center for Superconductivity broke the ambient-pressure temperature record for superconductivity, potentially enabling more efficient energy generation, transmission, and storage. • Superconductivity is a quantum phenomenon where materials exhibit zero electrical resistance and expel magnetic fields when cooled below a critical temperature threshold. • This breakthrough represents a major advancement in materials science that could have significant implications for energy infrastructure and technology development.

• Yuma, Arizona, hit a March record of 109°F on March 25, 2026, 28 degrees above normal, while sites near Yuma, Martinez Lake, Ogilby, and Winterhaven reached 112°F, tying the US high. • Sweltering conditions extended across several Southwest states and into Mexico, with Hermosillo setting a new March record at 108°F. • This extreme early heat signals intensifying climate patterns, challenging weather records and infrastructure in arid regions.
