Life isn’t fair. Neither is meiosis.

During meiosis, pairs of chromosomes get segregated so that gametes – egg and sperm cells – each get only one copy of each chromosome (instead of the pair that are in other types of cells). In women, the chromosome that doesn’t make it into the egg gets destroyed. But which one of the pair gets into the egg is not random; new work done at the University of Pennsylvania has shown that the chromosomes vie with each other for the honor, and have molecular mechanisms of pushing their way into the egg.

This is important for you because it’s cool. It gives a whole new dimension to the term “selfish genes;” their drive to get passed on kicks in preconception, and drags the whole chromosome into the egg.

Whatever you do – don’t feel guilty.

Erica Komisar, a therapist on the Upper East Side of Manhattan, has just released a book called Being There that urges mothers to stay home with their children for their first three years of life. Lauren Smith Brody aims to revolutionize workplace culture for new parents; she just released a book called The Fifth Trimester that gives new mothers the tools and agency to go back to work with a new baby. Read more about their very conflicting views about working mothers here.

This is important for you because the worst thing for a child’s well-being is a discontented, anxious, unhappy mother. Whatever your childcare plans are, try to feel settled with them – that will aid bonding with your child better than staying home and being miserable if that’s not what you can or want to do.

Odds are – your baby is a mathematician

Babies as young as six months can perceive and therefore understand the concept of probability, suggesting that such a sense might be innate. Researchers determined this by noting how the babies looked longer at unusual events – like a yellow ball shooting out of a tube that had previously only emitted blue balls. They paid more attention when the event was extremely rare. Read more here.

This is important for you because don’t underestimate your baby!! He is watching and learning from everything, and can probably understand more than we realize.

HCV screening

For the first time, the Society for Maternal-Fetal Medicine has just issued guidelines stating that pregnant women who are at increased risk for the hepatitis C (HCV) should be screened for the virus at their earliest prenatal visit. Those at risk include drug users, women with tattoos, those who have received organ transplants or blood transfusions, and those with other sexually transmitted infections. The cure for HCV has not been tested on pregnant women, but those who test positive can still make a plan to safeguard their and their fetus’ health. Read more here.

This is important for you because to ensure your child’s health you need to take care of your own.

The most popular article on The Pulse this week, by a long shot, was Is it Safe to Have Oral Sex During Pregnancy? The short answer: go for it. Read it here.
