2. Drain the potatoes (you may use the same water to blanch the green beans, below), then plunge them into a large bowl filled with ice water to stop the cooking. When they're cool, drain again. Toss them in a large roasting pan with the olive oil and the garlic.
3. Preheat the oven to 500 degrees Fahrenheit. Roast the potatoes, tossing them occasionally, until completely tender and lightly browned, 15 to 20 minutes. Toss with the parsley, salt, and pepper, and serve.
Jeremy Bailenson, founding director of Stanford University's Virtual Human Interaction Lab, is studying whether the experience of being a virtual cow will make people feel more empathy. "[Our previous work] showed that if you had occupied the avatar of another person, you showed empathy toward them," Bailenson says. "But no one had ever tried this with another species."
