Deadly “red sky” solar storm from 800 years ago discovered in ancient trees
A team of Japanese researchers has uncovered evidence of a powerful medieval solar storm dating to around 1200 CE, connecting historical accounts of blood-red auroras with carbon-14 spikes preserved in ancient tree rings. The discovery suggests the Sun was significantly more active during that period, exhibiting unusually compressed solar cycles. The findings carry modern implications, as a solar event of similar magnitude today could devastate global power grids and satellite infrastructure.

Fungus-powered farming delivers higher yields and better-tasting crops, says study
A natural extract derived from the fungus *Pseudozyma aphidis* has been shown to boost crop yields while simultaneously improving firmness and sugar content in produce like tomatoes and melons. Unlike live microbial cultures, the method relies on stable secretions, making it a reliable and scalable solution for large-scale agriculture. The discovery presents a compelling case for sustainable farming that refuses to trade productivity for quality.

Meltwater flushed methane from Greenland seabed during ice-sheet retreat, researchers reveal
Meltwater from retreating ice sheets flushed cold, fresh water across the northwest Greenland continental shelf, rapidly destabilizing methane hydrates locked in the seabed and triggering significant releases of the potent greenhouse gas. The findings, from an international research team, shed new light on a previously underappreciated mechanism linking ice retreat to methane emissions. Understanding this process has direct implications for projecting climate feedbacks as modern ice sheets continue to shrink.
