Roses

Everybody loves roses, but we'd probably love them even more if they didn't have those sharp thorns. Well, scientists have found a way of growing thornless roses, and their findings could lead to easier-to-harvest crops.

The long-awaited commercial release of the blue rose is set to take place in Japan next week (November 3). But before you go ordering a dozen or so for your loved one, check out the price – around ¥2,000-3,000 (US$22-32) each.
