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 ...

Early embryonic development is tumultuous. It involves a rapid sequence of events, including cell division, differentiation, and lots of compartments moving around within each cell. Like an orchestra ...

Two separate research teams used base editing to make single-nucleotide changes in human embryos this month, targeting genes tied to cholesterol regulation, blood disorders, and early development. One ...

Studying the early development of human embryos is challenging due to ethical constraints and technical difficulties. Therefore, animal models are often used to understand the biological processes ...

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 ...

Researchers from the University of Adelaide have discovered that the earliest days of embryo development have a measurable impact on a person's future health and aging. Professor Rebecca Robker, ...

Biologists have provided new insights on a longstanding puzzle in biology: How complex organisms arise from a single fertilized cell. Producing a new 'gene atlas' with 4-D imaging, the researchers ...
