Researchers developed a method that visualizes gene activity across an entire embryo with high spatial detail. The resulting ...

Scientists have long observed that embryos of different species within a phylum look quite distinct at early and late ...

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 ...

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 ...

Researchers at the Center for Embryology and Healthy Development (CRESCO) aim to find out why so many early embryos fail in their development. New insights into how maternal and paternal DNA is ...

Transposable elements are stretches of DNA that can move around the genome. Many of these DNA sequences originate from long ago, when viruses inserted their genetic material into our ancestors' ...

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 ...

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

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 ...

Cancers emerge from many different paths. One path begins early, in embryonic development, when a protein complex called PRC2 ...
