With weMERFISH, the MERFISHEYES atlas and the integration of live imaging, researchers now have a new tool at their disposal.

A discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...

Megan Molteni reports on discoveries from the frontiers of genomic medicine, neuroscience, and reproductive tech. She joined STAT in 2021 after covering health and science at WIRED. You can reach ...

At the end of the 4-cell stage, embryos divide to the 8-cell stage, forming many different shapes and high variability between embryos. Then, cells increase their surface tension which brings cells ...

A new discovery by researchers at the RIKEN Center for Biosystems Dynamics (BDR) in Japan upends decades of assumptions regarding DNA replication. Led by Ichiro Hiratani and colleagues, the ...

The earliest stages of mammalian embryo development are like an orchestra performance, where everyone must play at the exact right moment and in perfect harmony. New research identifies one of the ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

Live imaging of embryos at different stages. Chromosomes are labeled in magenta. 4-cell sister blastomeres are shown, along with 3D-reconstructed images of 2-to-4-cell and 4-to-8-cell divisions.
