A mathematical model developed by Rutgers University scientists can help explain why many pregnancies and IVF attempts fail. The study highlights the importance of understanding errors in female cell division, which increase with age and are linked to aneuploidy, a leading cause of early miscarriage and IVF failure.
The evolution of pregnancy in seahorses and pipefishes is linked to modifications of the adaptive immune system. Genomic analysis reveals divergent genomic rearrangements in the MHC II pathway, which may help study immune deficiencies.
