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

Under the microscope, MSK scientists studied how cells in a mouse embryo (green) move out and break away from their original tissue by contracting their surfaces (red). Studying this process, known as ...

“A central question has been: How do thousands of genes work together in an embryo, and how is their activity linked to the movement of cells?” says first author Yinan Wan. To answer this question, ...

Having a baby in space may sound like science fiction, but scientists are now studying whether it could actually work. New research suggests that one major challenge could be helping sperm find their ...

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

A new study suggests humans face barriers to reproducing in space, with microgravity disrupting sperm movement.

Lab-grown structures with the potential to develop into fetuses should be defined — and regulated — as embryos, some researchers say. It is time for a redefinition of the human embryo, a team of ...

Sperm may lose their ability to navigate in microgravity, raising new questions about whether human reproduction is possible ...

Cancer’s ability to spread throughout the body — a process known as metastasis — is responsible for the vast majority of cancer deaths. And a key feature of metastasis is that the cancer cells move, ...
