Overworking the dough will make the scones tough, so handle it as little as possible. The dough should come together into a rough mound and should feel slightly sticky.
Preheat oven to 425 degrees. Whisk together flour, wheat germ, sugar, baking powder, and salt in a large bowl. Stir in currants. Add cream, and stir just until combined.
Turn dough out onto a lightly floured work surface. Gently gather dough into a mound just until it holds together. Pat into an 8-inch circle about 1/2 inch thick. Cut into 8 wedges.
Arrange wedges on a baking sheet lined with parchment paper. Brush tops with melted butter. Bake until golden brown, about 20 minutes. Transfer scones to a wire rack, and let cool slightly. Serve warm or at room temperature with softened butter.
