New research is underway to decipher a fascinating biological puzzle—how some animals can naturally discard more than half of their genetic information during embryonic development. This radical ...

Multicellularity is one of the most profound phenomena in biology, and relies on the ability of a single cell to reorganize ...

A cell of the ichthyosporean C. perkinsii showing distinct signs of polarity, with clear cortical localization of the nucleus before the first cleavage. Microtubules are shown in magenta, DNA in blue, ...

At least 8% of the human genome is genetic material from viruses. It was considered ‘junk DNA’ until recently, but its role in human development is now known to be essential Researchers at the Spanish ...

The annual killifish lives in regions with extreme drought. A research group now reports that the early embryogenesis of killifish diverges from that of other species. Unlike other fish, their body ...

A new deep learning model performs a task that biologists have struggled with for centuries -- how to measure the incredibly complex process of embryonic development. Scientists have shown that the AI ...

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 ...

Researchers at the University of Connecticut have reported a novel bovine embryonic stem cell line with improved pluripotency ...

Scientists at the University of California, Santa Cruz (UCSC), used CRISPR to engineer cellular models of embryos that mimic what happens in the first few days after reproductive cells meet. These ...

With today's advanced microscopes, scientists can capture videos of entire embryos developing in real time. But there's a catch: turning those breathtaking images into clean, accurate trajectories of ...

Neural crest cells are a population of stem cells that invade the embryo in early development. They play a big role in what ...
