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 ...

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

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

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 ...

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 ...

Your heart isn’t fully on the left — but it does lean that way. The reason lies in early embryonic development, when microscopic cellular movements determine your entire internal layout.

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

Add Yahoo as a preferred source to see more of our stories on Google. As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of species over the course of ...
