Stem cell model created for rare childhood disease
Scientists at the University of Wisconsin-Madison, US, have successfully created a human model for spinal muscular atrophy (SMA) by using the induced pluripotency technique (iPS cells) to grow large numbers of affected nerve cells which can be studied in the laboratory. Researchers can now observe the process...

Is the embryo sacrosanct?: Faith in preimplantation genetic diagnosis
by MacKenna Roberts
In 1989, scientists first used preimplantation genetic diagnosis (PGD) - a technique that merges IVF with genetic testing, enabling couples with increased risk of passing a genetic disorder onto their children to screen and select only unaffected embryos for implantation. PGD involves the removal of a single cell from three-day-old IVF...
