All of Tiffany's trademark infringement claims against eBay were rejected — a knockout blow to the four-year-old lawsuit that had been closely watched by Internet companies as well as luxury goods makers seeking to stop the sale of counterfeit products online.

Tiffany & Co had alleged that eBay turned a blind eye to the sale of fake Tiffany silver jewelry on its site. EBay had countered that it was not in a position to determine which goods were knock-offs of the prestigious New York brand and had said the jeweler did not adequately participate in eBay's programs that help brand owners prevent fraud.

The judge, in a 66-page decision following a non-jury trial in U.S. District Court in Manhattan last November, said he was "not unsympathetic" to Tiffany and others who have invested in building their brands only to see them exploited on the Web. But he said the law was clearly on eBay's side.

What does a coral reef look like 50 years after being nuked? Not so bad, it seems. Coconuts growing on Bikini Atoll haven't fared so well, however.

The small study of two rhesus monkeys reveals that cells in their brains respond selectively to specific number values — regardless of whether the amount is represented by dots on a screen or an Arabic numeral.

For example, a given brain cell in the monkey will respond to the number three, but not the number one. The results suggest that individual cells in human brains might also have a fine-tuned preference for specific numerical values.
