Pre-embryos made in lab could spur research, ethics debates

For the first time, scientists have used human cells to make structures that mimic the earliest stages of development, which they say will pave the way for more research without running afoul of restrictions on using real ...

Stem cells can repair Parkinson's-damaged circuits in mouse brains

The mature brain is infamously bad at repairing itself following damage like that caused by trauma or strokes, or from degenerative diseases like Parkinson's. Stem cells, which are endlessly adaptable, have offered the promise ...

Uncovering the clock that sets the speed of embryo development

Why do pregnancies last longer in some species than others? Researchers at the Francis Crick Institute have found the clock that sets the speed of embryonic development and discovered the mechanism is based on how proteins ...

Genetic mutations may be linked to infertility, early menopause

A new study from Washington University School of Medicine in St. Louis identifies a specific gene's previously unknown role in fertility. When the gene is missing in fruit flies, roundworms, zebrafish and mice, the animals ...
