Scientists can now create embryo-like structures from animal and human stem cells in the lab, and recently, researchers unveiled the most advanced human embryo models yet, which resemble natural ...

Scientists have discovered a method of helping human stem cells thrive in an animal embryo—a key development in efforts to ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...

Scientists have used human skin cells to create fertilizable eggs capable of producing early embryos, an advance that could expand possibilities for fertility treatment, according to new research. The ...

Scientists have uncovered an unexpected function for a crucial protein involved in cell division. Reported in two consecutive ...

Researchers found that rabies virus uses a shape-shifting protein to hijack RNA and control vital cell functions. Viruses are astonishingly efficient, able to take over our cells and control essential ...

After a finite number of divisions, cells simply give up. As each round of replication trims their telomeres—the protective ...

Scientists can now create realistic human embryo models in the lab, leading some to suggest that we rethink how we legally define an embryo. When you purchase through links on our site, we may earn an ...
