The case of the unkindest cut of all

Drug companies won't make a male birth control pill, because men won't take it, according to the original engineer of the female birth control pill. Carl Djerassi says we could make a male pill today based on the same hormonal logic that guided development of the female pill. But he says no company is interested, because men won't take such a pill, because there might be a slight risk of impotence, and men care more about preserving their virility even in old age than about sparing their partner an unintended pregnancy.

"Scientists grew human prostate glands in mice. They combined mouse prostate cells with human embryonic stem cells, cultivated the combined tissue in the lab, and implanted it in mice, where it grew into functional human prostates. Advertised benefit: We can study the course, treatment, and prevention of cancer in these prostates without giving a damn about the hosts, since they're just mice.
