How and why preterm birth happens is still unclear, in part because research on pregnancy tends to focus on developmental biology.
Because hammerhead sharks give birth to live young, studying their embryonic development is much more complicated than harvesting some eggs and watching them develop in real time.
Early human development is a complex, multistep process that’s even more complicated to study in the lab. Models made from stem cells avoid some of the trouble with using real human embryos.
Of the many qualities that make the zebrafish a model organism, the fact that it shares 70% of the genes humans have makes it an ideal candidate for developmental biology research.
Human embryos are far more likely to die than come to term, an evolutionary trait seen across species. Laws granting personhood at conception ignore built-in embryo loss, with potentially grave consequences.
The newly discovered species – Qikiqtania – highlights evolution’s twisty, tangled path.
Unlike humans, many animals are able to regenerate their limbs after losing them. Giving the body the right conditions for regrowth might allow people to recover lost limbs as well.
Hox genes make sure all your body parts grow in the right place. Understanding how they work can reveal the process of evolution and lead to potential treatments for congenital birth defects.
Two research groups have turned human skin cells into structures resembling an early-stage human embryo, paving the way for exciting new research avenues, and opening up some tricky ethical questions.
