Cesarean births do not raise infant allergy risk in major Japanese cohort study

In a large Japanese birth cohort, cesarean delivery was not linked to higher risks of eczema, wheezing, atopic dermatitis, or asthma in infants at one year of age.

Micro-RNA in sperm proves vital for human embryogenesis

The sperm is not a passive supplier of genetic material to the egg. A study from Linköping University, Sweden, shows that certain molecules that come with the sperm, so-called micro-RNA, contribute to the development of the embryo several days after conception. The findings, published in the journal Nature Communications, may in the long term contribute to better diagnosis and treatment of involuntary childlessness.
