Surprising discovery offers new model for studying role of gap junctions in the brain

The same kind of neurons can have completely different wiring diagrams in the rat and mouse, as mice lack intercellular molecular channels known as gap junctions, researchers at Karolinska Institutet report in the scientific journal eLIFE.

Scientists identify gene responsible for evolution of recombination rates

Genetics is a crapshoot. During sexual reproduction, genes from both the mother and the father mix and mingle to produce a genetic combination unique to each offspring. In most cases, the chromosomes line up properly and crossover. In some unlucky cases, however, "selfish DNA" enters the mix, causing abnormal crossovers with deletions or insertions in chromosomes, which can manifest as birth defects.

Hypertension before pregnancy can raise risk of miscarriage

A new study has found that young women who have high blood pressure before their pregnancy are at a greater risk of suffering from a miscarriage. This is true for women who have not been diagnosed with hypertension but have an elevated blood pressure. The study was conducted at the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) and is due to appear in the May 2018 issue of the journal Hypertension.

Study provides insights into how male germ cells avoid genome instability

A group of researchers at Osaka University reported the function of GTSF1 in male germ cells. The study, which can be read in EMBO Reports, shows that GTSF1 is an essential factor for secondary piRNA biogenesis by regulating piRNA-mediated cleavage of target RNA.
