It's relatively easy to grow a bunch of animal cells to turn into a burger. But to grow a steak made of cultured meat is a trickier task. Bioengineers must create organized, three-dimensional tissues.
Surveys suggest fewer than half of Americans are looking forward to lab-grown meat. A moral psychologist examines common objections and why for the most part they're not logical.
Despite many claims, nobody knows for sure how the environmental footprint of lab-grown meat compares to livestock. An animal scientist says the issue is not black and white.
Cultured meat comes from cells in a lab, not muscles in an animal. While regulatory and technological aspects are being worked out, less is known about whether people are up for eating this stuff.
Based on a seductive story of providing food with zero consequences, cellular agriculture promises to get rid of the ethical, environmental and health costs of animal husbandry. But is that realistic?
