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 ...

Their “programmable” embryo-like structures, also known as embryoids, can be used to study the role of certain genes in early development The earliest days after fertilization, once a sperm cell meets ...

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 ...

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, ...
