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 ...

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.

People undergoing assisted reproduction view embryo transfer as their final step after completing an exhausting marathon. A ...

Week 3 of pregnancy is a critical stage when the embryo begins to grow rapidly. During this week, cells divide at an astonishing rate, laying the foundation for all future tissues and organs. This ...

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 ...

Researchers at the MRC Laboratory of Medical Sciences (LMS) and Imperial College London have shown for the first time that, ...

A team at ETH Zurich developed a new peptide-based organocatalyst that handles macrocycle formation from start to finish. Macrocyclic compounds are ubiquitous both in nature and in the chemical ...

Rowan University biology professor Natasha Shylo is exploring left-right asymmetry development with a grant from the National Institutes of Health.

Why doesn’t a ‘good’ embryo always lead to pregnancy in IVF? Explore key factors beyond embryo quality that affect IVF ...

Study finds that large embryo cells divide step by step using a mechanical ratchet system, challenging the textbook idea of a ...
