Controversial Chinese Scientist He Jiankui Back With New Gene-Editing Proposal
He Jiankui said that this experiment would involve abnormal fertilised egg cells that are typically considered unsuitable for implantation in women.

First Human Embryo Editing Experiment In US 'Corrects' Gene For Heart Condition
The work is particularly sensitive because it involves changes to the germ line, genes that could be passed on to future generations.

Scientists Create Part-Human, Part-Pig Embryo
The experiment, described Thursday in the journal Cell, involves injecting human stem cells into the embryo of a pig, then implanting the embryo in the uterus of a sow and allowing it to grow. After four weeks, the stem cells had developed into the precursors of various tissue types, including heart, liver and neurons, and a small fraction of the d...

Scientists Double Life Expectancy For Embryos In Petri Dishes, Raising Ethical Concerns
When scientists grow human embryos for lab research, they end their experiments at the 14-day mark. Until now, these internationally accepted guidelines (and the laws formed around them) have been largely self-regulating: The record for in-vitro gestation was just nine days, and most labs struggled to keep embryos alive longer then a week.

Scientists create embryonic-type stem cells without embryos
In experiments that could open a new era in stem cell biology, scientists have found a cheap and easy way to reprogramme mature cells from mice back into an embryonic-like state that allowed them to generate many types of tissue.
