There has never been a documented case of cancer found in a Naked Mole Rat, which is unusual as they can live to be 30 years old. Now biologists at the Unversity of Rochester believe they have found the reason.

The findings, presented in today's issue of the Proceedings of the National Academy of Sciences, show that the mole rat's cells express a gene called p16 that makes the cells "claustrophobic," stopping the cells' proliferation when too many of them crowd together, cutting off runaway growth before it can start. The effect of p16 is so pronounced that when researchers mutated the cells to induce a tumor, the cells' growth barely changed, whereas regular mouse cells became fully cancerous.

"We think we've found the reason these mole rats don't get cancer, and it's a bit of a surprise," say Vera Gorbunova and Andrei Seluanov, professors of biology at the University of Rochester and lead investigators on the discovery. "It's very early to speculate about the implications, but if the effect of p16 can be simulated in humans we might have a way to halt cancer before it starts."

Further research might reveal whether the findings will be applicable to humans. Link -via reddit

A 10-foot Great White Shark had been hooked already by a baited drum line off the coast of Queensland, Australia when it was attacked and bitten by a much bigger fish. Based on the bite marks, the attacker is presumed to be a 20-foot long Great White shark. Swimmers were warned away from the area of Stradbroke Island.

"That cannibal thing is what great whites do; they'll eat anything, including their own kind," Hugh Edwards, a local shark expert, told Australia's 7 News. "It would be sensible not to swim in that area for a little while."

On October 26th, 1977, a hospital cook in Somalia named Ali Maow Maalin was diagnosed with smallpox. What makes this so remarkable is that no naturally-occurring cases of smallpox have been diagnosed in the 32 years since.

The global eradication of smallpox was certified, based on intense verification activities in countries, by a commission of eminent scientists on 9 December 1979 and subsequently endorsed by the World Health Assembly on 8 May 1980[10][48] as Resolution WHA33.3. The first two sentences of the resolution read: "Having considered the development and results of the global program on smallpox eradication initiated by WHO in 1958 and intensified since 1967 … Declares solemnly that the world and its peoples have won freedom from smallpox, which was a most devastating disease sweeping in epidemic form through many countries since earliest time, leaving death, blindness and disfigurement in its wake and which only a decade ago was rampant in Africa, Asia and South America."[49]

Smallpox once killed millions of people every year, and may have been responsible for up to 500 million deaths in the 20th century. National vaccination programs began in the early 1800s, but it was a global push by the World Health Organization begun in 1958 that finally led to the eradication of the disease worldwide.

The term ghost ship can refer to a mysterious apparition of a ship when a ship is not really there, or it can refer to an abandoned ship found with no crew or passengers, usually under mysterious circumstances. Both kinds are listed in these ten stories spooky enough to share with anyone to whom you want to give nightmares. Pictured is the Baychimo, used in Arctic waters until it became trapped in ice in 1931. The crew was airlifted and the ship abandoned. However, the boat survived to mysteriously float on its own for decades. It was last seen in 1969. Link -via Unique Daily

According to The Empire Strikes Back, there's no smell in the galaxy as bad as the inside of a dead Taun Taun. When Chris and Julia Trevas got married, they hired Food Network baker Courtney Clark to make the cakes. The groom's cake was in the shape of a dead Taun Taun, complete with Luke Skywalker inside! I would guess the authentic smell was not included. Link -via Boing Boing

The Cornish Duck Company checks its eggs for viable embryos. They noticed one egg had two embryos, and were prepared with a camera when it hatched.

Local vet Barrie Fleming, who advised the farm's owners, Roger Olver and Tanya Dalton, on the hatching, said they had "every reason to be excited by the birth" as it was a very rare occurrence.

The BBC has the video. Link -via Arbroath

Customs officials at the Dublin Airport at first thought the x-ray showed a toy dog in the suitcase, but they opened it up and out popped a live puppy! A Bulgarian man on a flight from Madrid was trying to smuggle the young chihuahua.

It is understood the dog was being smuggled in as a gift for someone.

Legally, dogs must have clearance and a health certificate before being brought into the country.

The animal, which Mr Broni said seemed tired but unharmed, was handed over to Department of Agriculture officials where it was placed in quarantine.

The man was not detained, but a file is being compiled on the case. Link -via Unique Daily

The laws of the internet were never legislated, but passed into law by being evident over and over again. I was familiar with most of these laws, but some I didn't know had names or documented origins.

4. Skitt’s Law:  Expressed as "any post correcting an error in another post will contain at least one error itself" or "the likelihood of an error in a post is directly proportional to the embarrassment it will cause the poster."
It is an online version of the proofreading truism Muphry’s Law, also known as Hartman's Law of Prescriptivist Retaliation: "any article or statement about correct grammar, punctuation, or spelling is bound to contain at least one eror".

That's nice to know. Link -via Digg
