The evolution of women's erotic dreams.

(Continued from Page 1)

Tobacco companies are shifting their business toward selling smokeless tobacco in a pouch, aka snus. R.J. Reynolds is test-marketing it in two cities; Philip Morris is trying it in two others. Rationales: 1) Snus users get less cancer than smokers. 2) They produce no passive smoke. 3) This is a way to sell more tobacco as the cigarette market wanes. 4) Unlike regular smokeless tobacco, the new products put the tobacco in something like a tea bag, so you don't have to spit. Companies' spin: Great taste, less killing. Critics' view: It's wrong to market snus as safe, since it's still addictive and causes pancreatic cancer.

* Correction, June 14, 2007: The item on captchas (Completely Automated Public Turing Test to Tell Computers and Humans Apart) originally said that test images had become so hard to decipher that a company's chief technology officer flunked 75 percent of them. The source article actually said that the CTO passed 75 percent of the tests, which were administered by Ticketmaster. For this mistranslation, Human Nature blames … human error.
