Forward genetics approach reveals the factor responsible for carbon trade-off in leaves
Plants store carbon in two primary forms: starch and triacylglycerols (TAGs). Starch is mainly stored in chloroplasts in leaves, where it serves as a readily available energy source, while TAGs are stored in seeds for long-term energy storage….

New human ‘multi-zonal’ liver organoids improve injury survival in rodents
One reason why our livers excel at clearing waste from our blood system is that the organ functions according to three key “zones” that perform specific major tasks. So, if scientists hope to create self-growing patches of liver organoid tissue…
