IEEE Potentials > 2017 > 36 > 4 > 15 - 18

Even to the casual observer, the real hero of Star Wars can be a matter of debate. While Luke Skywalker's heroics in his X-wing starfighter sealed the Rebellion's victory, he would not have a target to destroy were it not for a certain short, round, sassy astromech droid who faithfully carried the plans from Princess Leia.... well, you know the story. The point being, R2-D2 is a fan favorite for many...

Neuromuscular Disorders > 2012 > 22 > 9-10 > 848

Spinal muscular atrophy (SMA) is caused by the reduced expression of the survival of motor neuron (SMN) protein due to the loss of functional SMN1 gene and alternative splicing of exon 7 in the SMN2 gene. We are pursuing innovative drug discovery strategies aimed at restoring the production of the SMN protein by modulating SMN2 alternative splicing. Panels of cell based assays and animal models have...
