Rye pollen slows tumor growth in animal models of cancer. Chemists determined the 3D structure of the bioactive molecules in rye pollen. With new blueprint, researchers could develop strategies for cancer treatment.

By studying genetic data from nearly 140,000 IVF embryos, scientists have with unprecedented detail revealed why fewer than half of human conceptions survive to birth. The research uncovered the strongest evidence yet for how common genetic differences leave some individuals more vulnerable to pregnancy loss.

The vast dataset allowed the Johns Hopkins University-led team to demonstrate robust connections between specific variations in a mother’s DNA and their risk of miscarriage.
