The aim of the research is not to create synthetic, or artificial life, but to produce working models that will allow scientists to study crucial stages in human development.
Researchers have taken a major step towards creating synthetic embryo-like structures that mimic real human embryos with most of the fundamental features of the earliest stages of life.
The latest study, from researchers at the Weizmann Institute in Israel, built on the work of a number of recent experiments using human embryonic stem cells and has created the most complete embryo produced so far. "This is a landmark study that opens up new avenues for research into human development" said Prof Alfonso Martinez Arias at Pompeu Fabra University in Barcelona, Spain.
The aim of the research is not to create synthetic, or artificial life, but to produce working models that will allow scientists to study crucial stages in human development that are obscured from view as early-stage embryos develop inside the womb. The research"is a step towards opening a window on the period of human development where many pregnancies fail and which has been really difficult to study up until now," said Dr James Briscoe at the Francis Crick Institute in London.Here, the researchers use stem cells from donated human embryos which were then"coaxed" using chemical cues to develop into the four basic cell types of the early embryo that give rise to all the tissues and organs of a fully-formed human.

Younger generation gets sick earlier and more often than the older generation, researchers findA research group in the sociology of medicine studies the development of health in the population and comes to surprising results. Improvements in living conditions, advances in medicine and general knowledge about healthy lifestyles are of particular benefit to the older generation. The younger individuals get sick earlier and more often. This poses challenges for the health system, the economy and every individual.
