Revealed: The mystery of Rudolph‘s nose

Rudolph the Red-Nosed Reindeer‘s snout has been immortalised in movies, books and song.

But until now, no-one has offered a scientific explanation for the glow that allows the world’s most famous antlered herbivore to guide Santa‘s sleigh through the night before Christmas.

In a study released Monday, researchers in the Netherlands and Norway used a hand-held microscope to examine the nasal lining of five healthy humans, two reindeer and a sixth person with a non-cancerous nasal growth.

Reindeer noses have 25 percent more blood vessels than human noses, according to the tongue-in-cheek investigation, published by the British Medical Journal (BMJ) in its Christmas edition.

The tiny blood vessels provide plentiful oxygen-carrying cells and help control the body’s temperature, showed their findings, which were backed by an infrared image of a reindeer after exercise.

“Rudolph‘s nose is red because it is richly supplied with red blood cells, comprises a highly dense microcirculation, and is anatomically and physiologically adapted for reindeer to carry out their flying duties for Santa Claus,” the paper observes.

Rudolph’s round-the-world feat has been closely scrutinised by physicists.

In order to deliver presents to children in around 100 million homes where the Santa tradition is observed, he would have to travel at around 1,000 kilometres (650 miles) per second, they estimate.

At such speeds, the reindeer, Santa and the sleigh would be vaporised by friction with the air, along with the gifts and any little elvish helpers who came along for the ride.

Rudolph would need to deploy an ion shield to protect them, or exploit loopholes in the space-time continuum so that they travelled between dimensions in order to deliver the presents on time. (AFP)

루돌프 코가 빨간 진짜 이유 밝혀져!


루돌프의 코가 빨갛다는 이야기는 오래도록 내려왔지만, 그 이유에 대한 과학적인 설명은 없었다.

네덜란드와 노르웨이 연구팀은 사람과 순록의 코 내벽을 핸드헬드 현미경으로 관찰했다. 그 결과 순록의 코에 사람보다 혈관이 25% 가량 더 많이 있었다. 이는 영국의학저널(British Medical Journal) 크리스마스 에디션에 게재되었다.

코에 있는 작은 혈관에는 산소운반세포가 많고 혈관은 체온을 조절하는 역할을 한다. 이는 운동을 한 순록의 적외선촬영에서 드러났다.

“루돌프 코는 빨갛습니다. 왜냐하면 혈관이 많기 때문이지요. 산타클로스와 달리는 임무를 수행하기 위해 진화했습니다.”

과학자들은 전세계 아이들에게 선물을 주기 위해 1억 개의 가정에 방문하기 위해서는 시속 1천 km로 달려야 한다고 말했다. 그러한 속도라면 썰매에 엄청난 마찰이 일어날 것이다. 이로 인해 루돌프가 제시간에 선물을 모두 배달하기 위해서는 이온막이 필요하다는 과학적 추측이다. (코리아헤럴드)
