Resumen de Better than nature
Synthetic DNA circuits inserted into human stem cells could soon allow people to build new organs with unprecedented precision and speed. The circuits can be designed on a computer and assembled from ready-made parts ordered online. The technique could prove an efficient way of making organs for transplant without the worry of rejection, and raises the tantalizing possibility that it might one day be possible to upgrade the organs they were born with. Human cells have already been used to create a tiny liver and a set of neurons. Here, Heaven discusses how being able to dictate what cells do means people could improve what they're born with.
