‘Edited’ human embryos reveal secrets of our development — and fuel ethical debate
Ethical discussions are urgently needed as genome-editing science advances, some researchers say.

Once the realm of science fiction, the idea of making Mars habitable is gaining traction. Nature consulted with key scientists to develop this experimental adventure.
Cholesterol carried by low-density lipoprotein (LDL) drives heart disease and is cleared by liver cells expressing the receptor LDLR. A cell-signalling mechanism has been discovered through which high cholesterol promotes the enzyme-mediated degradation of LDLR. Blocking this enzyme restores LDLR levels in liver cells, suggesting a new strategy for treating high cholesterol.
