Scientists have developed a new class of microscopic antibody fragments capable of functioning inside human cells, overcoming a long-standing limitation in biomedical science.

Scientists have created egg-like cells capable of fertilization using DNA from ordinary skin cells in what could be a major breakthrough for infertility research. Using a newly developed technique to ...

Creating human eggs from adult cells just got one step closer to reality. A technique used in cloning combined with fertilization and a bit of chemical coaxing caused human skin cells to produce eggs ...

In a demonstration that could help pave the way for gene therapies with fewer side effects, several human cell types have ...

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 ...

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 ...

What previously required months or years of specialised lab work can now be done in hours or days thanks to its integrated ...

Researchers are learning how to refill the energy reserves of aging human cells, turning a long-standing metaphor about “cellular batteries” into a literal engineering challenge. By training healthy ...

Oregon scientists used human skin cells to create fertilizable eggs, a step in the quest to develop lab-grown eggs or sperm to one day help people conceive. But the experiment resulted in ...
