New York City's GreeNYC campaign has a logo that looks like an apple. It makes sense, as the city is known as The Big Apple. But Apple Inc. says it infringes on their trademark. The computer company has filed in injunction in New York’s trademark application.

The Cupertino, California, company calls for the trademark to be denied, claiming the city's logo will confuse people and "seriously injure the reputation which [Apple] has established for its goods and services."

New York says: Getdafugoutaheya.

"The city believes that Apple's claims have no merit and that no consumer is likely to be confused," says Gerald Singleton, the intellectual-property lawyer representing the Big Apple. "This well-known city is using its new design in a variety of contexts that have absolutely nothing to do with Apple Inc."

The dispute is likely to take several months to resolve. http://www.wired.com/techbiz/it/news/2008/04/apple_vs_apple#

Scientists are working on making teeth regrow the crystals that make up dentin and enamel. This process could eliminate drilling and filling to combat tooth decay. Sally Marshall, a professor at the University of California at San Francisco, is looking for a way to catch decay early and cause teeth to start “remineralizing”.

Marshall's newest work, which has been accepted for publication in the Journal of Structural Biology, focuses on regrowing dentin in damaged teeth with the help of a calcium-containing solution of ions (electrically charged particles).

By putting a layer of the solution on individual test teeth, Marshall has already been able to remineralize some parts of the teeth. The challenge is to get the crystals to regrow throughout the dentin.

To heal properly, the crystals need to form from the bottom of the tooth up to the enamel. Marshall isn't sure whether that's happening yet, but she is confident that she'll find a way to restore dentin functionality over the next few years.

When this technology progresses to popular use, our grandchildren won’t believe our stories about the dentist’s drill! Link

The recent video of a velvet worm may have given you the willies, but you’ll love the tiny whimsical paintings of Nathan Mazur!

While browsing through an art supply store, local cartoonist and animator, Nathan Mazur, came upon some tiny canvases about the size of a Zippo lighter. Though meant as a novelty item, he purchased a few and used them to paint cartoony, life-sized pictures of bugs.

Wee Beasties is an exhibit of 50 miniature paintings (2” by 2.75”) of insects, worms, and other creepy crawlies. They depict everything from the common cockroach, to the cryptic water bear, all in the artist’s seemingly innocent, saccharine-colored, cartoon style.

The velvet worm is on the left. To the right is (you guessed it) a lightning bug. The exhibit in Pittsburgh runs through April 5th. Most of the miniatures are sold, but you can see them all in Mazur’s online gallery. Link -thanks, Nathan!

A four-month old kangaroo was in his mother’s pouch when she was killed by a car in Torquay, Victoria, Australia. The unharmed joey would normally have died, but Rex the mixed-breed dog took the roo to his owner, Leonie Allan.

"I'd taken Rex for a walk and we'd gone past the dead kangaroo that morning, and later I was working out the front and he started pointing," Ms Allan said.

"I was worried he'd found a snake and called him back, but when he returned he dropped the joey at my feet.

"He obviously sensed the baby roo was still alive in the pouch and somehow had gently grabbed it by the neck, gently retrieved it and brought it to me."

The kangaroo was calm and even snuggled up with Rex. Now named Rex Jr, the joey is under the care of the Jirrahlinga Wildlife Sanctuary, and will be released at 18 months of age. Link -via Arbroath

One of the strangest April Fool hoaxes ever was pulled of by one Isaac Bickerstaff, an astrologer who published an almanac predicting the events of the year 1708. One of his predictions was the death of rival astrologer John Partridge on March 29th. On April first, news of Partridge’s death was all over London, and funeral arrangements were being made. The only problem was that Partridge was not dead. However, he spent the rest of his life trying to live down the hoax. Read the entire story, and the surprising true identity of Isaac Bickerstaff, at Damn Interesting. Link

The Harvard Lampoon’s latest issue came out April first entitled National Geographic. Staff members at National Geographic helped the student magazine to ensure the parody stayed true to the magazine’s style. Stories include Mongolia’s Wildest Waterparks, speculation on the nature of light, and an expose on the manufacture of lava lamps.

Editors from National Geographic could not be reached Monday, but the magazine released a facetious statement.

"Editors are unavailable for comment, having left the country … as usual," it said. "There are reports of laughter from parts of the building, but that could just be because we are a fun place to work."
