Mitochondrial Transfer: The making of three-parent babies

by Catherine Weiner figures by Rebecca Clements The question, “where do babies come from?” used to have a simple answer. A man and woman have sex, the male sperm fertilizes the female egg, and 9 months later a baby is born. But in today’s world, medical advances have complicated this answer. For example, a new technique called mitochondrial transfer has recently emerged to prevent the … Continue reading Mitochondrial Transfer: The making of three-parent babies

Mother’s Mitochondria

While celebrating Mother’s Day over brunch, don’t just thank your mom for all her love and nurture, remember to also mention mitochondria, like Leah Bury, our featured artist for June, suggests in her science-y Mother’s Day card. Mitochondria are the powerhouses of the cells, which means they generate the energy that keeps cells (and by extension you) running. Interestingly, we inherit our mitochondria entirely from … Continue reading Mother’s Mitochondria

Leah Bury

Hi, I’m Leah – a cell biologist and a triplet, originally from Frankfurt, Germany. Having shared a womb with my two brothers probably genetically predestined me to become a scientist, as I wanted to learn more about the fascinating ways in which organisms grow, develop, and reproduce. In my current postdoc work at the Whitehead Institute in Cambridge, MA, I am driven by my passion … Continue reading Leah Bury

It’s a boy! Baby is born with DNA from three “parents”

  A now five-month-old boy was the first child to be born via spindle nuclear transfer, a controversial fertilization procedure that incorporates genetic material from three different people.  Most of our genes are located in the DNA found in a cell’s nucleus, but a few reside in tiny compartments called mitochondria.  While rare, mutations in mitochondrial DNA can result in devastating disorders that often cannot … Continue reading It’s a boy!
