Scientists have created miniorgans from cells floating in the fluid that surrounds a fetus in the womb - an advance they believe could open up new areas of prenatal medicine.

Miniorgans, or " organoids," are tiny simplified structures that can be used to test new medical treatments or study how the real organs they mimic work, whether they are healthy or diseased.

Turkish conjoined twin brothers Yiğit and Derman will set off on their journey back to Turkey after more than six months of medical operations and healing in the British capital London to separate them.

The two-year-old twins, who were born with their heads joined to each other, will be taken back to Turkey early on June 9 in an ambulance plane sent by the Turkish Health Ministry.
