A new study has uncovered how an exceptionally scarce protein can orchestrate the assembly of large-scale gene-silencing structures inside cells, and what happens when that process breaks down. The ...

Late in 2025, we covered the development of an AI system called Evo that was trained on massive numbers of bacterial genomes. So many that, when prompted with sequences from a cluster of related genes ...

6 core challenges that researchers must consider as the race to create models that are ever closer to real human embryos ...

Scientists have uncovered a surprising new way that giant embryonic cells divide—without relying on the classic “purse-string” ring long thought essential for splitting a cell in two. Studying ...

Growing tissues can crack, break, and dissociate to form structures that can later withstand immense forces.

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.

Passing on fundamental life lessons from parent to offspring is not unique to humans and animals. Ferns do it too. Not with words, but through pressure. By applying force at precisely the right ...

Conditional genetics and single-embryo RNA-seq show that SETDB1 extinguishes the transient, retroelement-driven transcriptional programs of the totipotent two-cell state to facilitate the exit from ...

Study in a Sentence: Scientists have developed a new human-based endometrial model to study embryonic implantation in the early stages of pregnancy. Healthy for Humans: For pregnancy to begin, an ...

New stem cell-based embryo model reveals previously unknown communication between early tissues that become the spine and muscles in the central part of the body. From the moment an embryo starts to ...
