A nuclear winter is a theoretical concept, but if the climate scenario expected to follow a large-scale nuclear war, in which smoke and soot from firestorms block sunlight, came to fruition, global temperatures would sharply drop, extinguishing most agriculture. A nuclear winter could last for more than a decade, potentially leading to widespread famine for those who survive the devastation of the bomb blasts. Now, a team led by researchers at Penn State have modeled precisely how various nuclear winter scenarios could impact global production of corn — the most widely planted grain crop in the world. They also recommended preparing “agricultural resilience kits” with seeds for faster-growing varieties better adapted to colder temperatures that could potentially help offset the impact of nuclear winter, as well as natural disasters like volcanic eruptions. 

Researchers at the University of Missouri recently discovered that soybeans have a natural defense strategy — called differential transpiration — that helps protect the plant’s reproductive tissues (flowers and seed pods) during extreme weather conditions. Think of it as nature’s version of targeted air conditioning.

In a new study published in Molecular Plant-Microbe Interactions®, researchers discovered that potato plants rely on salicylic acid (SA)—a plant hormone best known for its role in triggering immune responses—to protect their roots from this unusual invader
