Embryos in pregnancies that end in miscarriage take longer to develop in the womb than those in pregnancies that result in live births, according to new research published today (Monday) in Human ...

Around eight days after fertilization, the human embryo implants in the endometrium (the tissue that lines the uterus). After implantation, it enters a developmental phase that is not well understood ...

Bioengineering researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a soft, thin, stretchable bioelectronic device that can be implanted into a ...

Two to three weeks after conception, an embryo faces a critical point in its development. In the stage known as gastrulation, the transformation of embryonic cells into specialized cells begins. This ...

A new study from the MRC Laboratory of Medical Sciences (LMS) in London, UK reveals how ancient viral DNA once written off as "junk" plays a crucial role in the earliest moments of life. The research, ...

The complex 3D shapes of brains, lungs, eyes, hands, and other vital bodily structures emerge from the way in which flat 2D sheets of cells fold during embryonic development. Now, researchers at ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

New research from the University of Newcastle has revealed that PFAS levels matching those found in the Williamtown contamination zone could significantly alter male reproductive health in ...

Researchers have discovered a key transition in early embryonic development is facilitated by decreasing levels of a viral protein inserted into the DNA of our early animal ancestors. Researchers at ...

A new open-source software tool helps see the inside of 3D and 4D images, providing insight into embryonic mouse heart development. 3D and 4D imaging, which is 3D imaging combined with time to show ...
