First Artificial Wombs: Researchers now grow human embryos in a laboratory to study pregnancy

We all know how to get pregnant or at least should know, but despite so many tips out there boosting the chances of conceiving, the actual first 2 weeks of pregnancy remain an undetectable mystery to science.

A pregnancy test is usually done via markers detecting hormones in specific substances like urine and blood. At the very beginning, though, these hormone levels are just too low to register a positive test. Without actually looking into the womb, nobody can watch fertilized eggs grow. Yes, we understand the process going on, as the embryo (which is basically a mass of cells called blastocyst) starts dropping its outer layer to implant within the uterine lining.

However, only a couple of weeks ago researchers from Rockefeller University were the first to witness and even raise human embryos in a laboratory for the maximum ethically allowable time of 13 days.
