Why plant cells need heme: Hidden signal reshapes photosynthesis gene control

Quantum mechanics, unlike classical physics, allows objects to exist in more than one state at the same time. This idea is often illustrated by Schrödinger's cat, imagined as being both alive and dead until it is observed. In the laboratory, physicists can create less dramatic but very real versions of this effect by placing atoms, light or motion into two distinct quantum states at once. Creating and controlling these superpositions is essential for applications ranging from quantum computing t

Maize (Zea mays L.) plays an important role in global food security. During 9,000 years of maize domestication and breeding, however, protein content was not a major breeding target. Consequently, many beneficial gene variants associated with higher protein content were gradually lost from cultivated maize. As a result, modern maize varieties often have low seed protein content, leading to a heavy reliance on imported soybean meal for livestock feed.

Agriculture today is a massive, globally interconnected industry. That interconnectivity has brought jobs and varied foods to people who might not otherwise be able to access them.
