A group of college students who called themselves Fangs A Lot have opened a business in Britain named Animal Solutions. They sell false teeth for cats. And dogs and other animals, as needed.

Cats have notoriously bad dental problems. Cat owners seldom brush their cats' teeth or scrape the surfaces of the teeth to remove plaque. By the time a cat is 3 or 4 years old, she may already have periodontal disease that can lead to tooth loss. Tooth loss may also come about as a result of tooth breakage, particularly in the canine teeth.

Will the business take off? Only time will tell. Link -via Dump Trumpet

Salvador Dali and photographer Phillipe Halsman teamed up to produce the art photo Dali Atomicus, the picture of airborne water and cats. It wasn’t easy; there were 28 takes before the finished product was shot.

"after each exposure, while the assistants mopped the floor and reclaimed cats, Halsman developed the film to see the progress in the composition. Accidents would happen. The water, intended for the cats, would cover Dali's face instead."

When Lee Spievack sliced off the end of his finger a few years ago, his brother sent him some powder to sprinkle on it. In four weeks, his fingertip had grown back! Dr. Steven Badylak explains:

That powder is a substance made from pig bladders called extracellular matrix. It is a mix of protein and connective tissue surgeons often use to repair tendons and it holds some of the secrets behind the emerging new science of regenerative medicine.

"It tells the body, start that process of tissue regrowth," said Badylak.

Badlayk is one of the many scientists who now believe every tissue in the body has cells which are capable of regeneration. All scientists have to do is find enough of those cells and "direct" them to grow.

"Somehow the matrix summons the cells and tell them what to do," Badylak explained. "It helps instruct them in terms of where they need to go, how they need to differentiate - should I become a blood vessel, a nerve, a muscle cell or whatever."

Scientists are studying the matrix to grow organs for transplant and to repair war wounds. Link -via Digg

Friday, March 21st is Good Friday for Christians, but it’s also a sacred date for many other religions. People are celebrating Good Friday, Purim, Narouz, Eid Milad an Nabi, Small Holi, and Magha Puja. That doesn’t happen often.

Ed Reingold and Nachum Dershowitz, co-authors of the books Calendrical Calculations and Calendrical Tabulations, determined how often in the period between 1600 and 2400 A.D. Good Friday, Purim, Narouz and the Eid would occur in the same week. The answer is nine times in 800 years. Then they tackled the odds that they would converge on a two-day period. And the total is ... only once: tomorrow. And that's not even counting Magha Puja and Small Holi.

TIME has an explantion of these holidays and how they are set in the calendar. Link -via Metafilter

Scientists who just returned from a survey of the Ross Sea near Antarctica have found giant versions of sea creatures, such as jellyfish with 12-foot tentacles and a starfish measuring 2 feet wide! Some of the 30,000 specimens collected could be entirely new species.

A 2,000-mile journey through the Ross Sea that ended Thursday has also potentially turned up several new species, including as many as eight new mollusks.

It's "exciting when you come across a new species," said Chris Jones, a fisheries scientist at the U.S. National Oceanic and Atmospheric Administration. "All the fish people go nuts about that — but you have to take it with a grain of salt."

The finds must still be reviewed by experts to determine if they are in fact new, said Stu Hanchet, a fisheries scientist at New Zealand's National Institute of Water and Atmospheric Research.

The Astronomy Picture of the Day is a gorgeous sunset in honor of the Vernal Equinox.

To celebrate the equinox, consider this colorful view of the setting Sun. Recorded last June from the International Space Station, the Sun's limb still peeks above the distant horizon as seen from Earth orbit. Clouds appear in silhouette as the sunlight is reddened by dust in the dense lower atmosphere. Molecules in the more tenuous upper atmosphere are preferentially scattering blue light.

Jeff Atwood of Coding Horror has a helpful and informative article about rechargeable batteries. The beauty of it is the unabashed joy he takes in his new charger.

...I ended up tossing my generic "rapid" chargers in favor of the majestic, glorious, and surprisingly inexpensive La Crosse Technology BC-900 AlphaPower battery charger.

Seriously, just look at this thing. It's a geek's dream.
