An international research team has provided a detailed insight into how the spatial organization of genetic material is established in the cell nucleus of early embryos within the first hours after ...

Researchers at Karolinska Institutet have mapped how small RNA molecules, such as the recently Nobel Prize-awarded microRNAs, control cell development in the human embryo during the first days after ...

From the moment an embryo starts to take shape, two-way communication is critical for making sure tissues and organs develop correctly. Subscribe to our newsletter for the latest sci-tech news updates ...

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...

Over half of our genomes consists of thousands of remnants of ancient viral DNA, known as transposable elements, which are widespread across the tree of life. Once dismissed as the "dark side" of the ...

How does a tiny cluster of cells become an embryo with a head, trunk, and tail? And how do thousands of genes coordinate this development? A new imaging method makes it possible to visualize the ...

Designer babies may sound like science fiction, but they’re becoming increasingly possible as gene editing technology to treat and prevent genetic diseases evolves. How scientists should use it is a ...

When the egg and sperm fuse, a comprehensive reorganization of DNA begins within the nucleus. Epigenetics plays a crucial role in this process, regulating gene activity through chemical modifications ...
