Non-invasive prenatal diagnostic testing for Down Syndrome: Previously, women underwent invasive testing such as amniocentesis or chorionic villus sampling (CVS).

Stem cell educator therapy: Chinese and US researchers have produced remarkable results for this new treatment of obtaining stem cells from human cord blood to "re-educate" misbehaving immune cells. This result was published in the open-access journal BMC Medicine in January 2012, and offers hope for Type 1 diabetics and potentially may also be used to treat other auto-immune diseases if the approach lives up to early promise.
