Scientists are proposing that the legal time-frame for keeping embryos alive should be extended past the current 14 days.
They claimed that this would enable scientists to better understand how babies develop in the womb, with Professor Magdalena Zernicka-Goetz of Cambridge University saying it would be "useful" to extend the limit by a few days. The proposal poses serious ethical concerns; Andrea Williams commented that this is another attack on the sanctity of life.
