News of the gene-edited babies excludes images of the children’s mother. Cutting her out of the picture underscores the idea that the mother is obsolete and babies can be created in the lab.
Problems in facial development can occur with the skull, face, blood vessels, muscles, jaws and teeth. But it’s the hard palate forming the roof of your mouth that’s most commonly affected.
The genes in our cells’ mitochondria are passed on in a different way than the vast majority of our DNA. New studies shed light on how the unique process isn’t derailed by mutations.
Americans have moved on from worrying about ‘test-tube babies’ – but there are still ethical challenges to resolve as reproductive technologies continue to advance.
The news may have come as a surprise, but it probably shouldn’t have. A bioethics expert walks through how big a deal this announcement is – and what we should be considering now.
A new evolutionary perspective on what’s been a medical paradox: Why does the body use inflammation to regulate aspects of pregnancy when inflammation is also a big threat to pregnancy?
Taking the placenta as a case study, researchers are able to piece together how new organs evolve, by repurposing old tissues and using them to do new jobs.
In 1997, scientists announced they’d created a healthy sheep cloned from another ewe’s mammary gland cell. Two decades on, the technique is being refined and applied to new challenges.
Stem-cell scientists have to work within many limitations placed on their research. One of these is the 14-day rule that outlaws research on pure human embryos over two weeks old.
Recent animal studies show the developing embryo is highly susceptible to environmental changes and the actions of the mother in early stages of pregnancy.
Scientists have discovered the genetic “switch” that causes many animals, including fish, frogs and humans, to look the same at a certain point in embryonic development.
Clinics aren’t compelled to disclose their success rates, so it’s impossible to compare all clinics. Even when they do, the pretty graphs on clinic websites can be difficult to understand.
Aneuploidy – when a cell has an irregular number of chromosomes – is a major cause of pregnancy loss. Scientists may have uncovered a gene that increases the risk of aneuploidy.
