Iron fuels immune cells – and it could make asthma worse

Asthma attacks can result from immune cells overreacting to a harmless allergen. Tamping down iron levels in certain immune cells can help control their activity.
Organoids can replicate each component of the human heart, from its chambers to its veins. Yonatan R. Lewis-Israeli et al. 2021/Nature Communications

Engineering mini human hearts to study pregnancy complications and birth defects

Human heart organoids allow researchers to study the developing heart while avoiding the ethical issues of using human embryos and the imperfections of animal models.
