Random by design: Flickering genes may spend energy to achieve precision
Inside the cell nucleus, genes must be turned on and off with precision to regulate biological processes. The first models of gene regulation were developed in the 1960s, yet modern science continues to uncover new layers of control. A new study involving researchers from the Ins

Atoms tell different stories when light hits a molecule in trillionths of a second
Researchers have captured how a molecule redistributes energy after absorbing light, differentiating the roles of individual atoms in the process. They used X-ray flashes from the European XFEL to show that different atoms in the same molecule can reveal different aspects of the

Evolutionary history shapes plant carbon storage strategies worldwide
Two types of carbohydrates are important to plants—structural carbohydrates (which form cell walls) and nonstructural carbohydrates (NSCs). The latter group represents plants' stored energy reserves, which can be used to survive cold or drought; regrow after damage; recover from
