While reindeer no longer live in our backyards, if they ever happen to be flying by, watch for their luminous blue eyes. It turns out they probably don’t really need a glowing red nose to see ...

Reindeer herding and hunting are a key part of the culture and economy of the indigenous Sami population in Sweden’s North. The normal body temperature of a reindeer is around 38 degrees Celsius.

Reindeer (Rangifer tarandua) are herbivores, which means they eat plants. But because they live in the Arctic, where snow and ice covers the ground for most of the year, they can’t be too fussy.

In Sweden, herding reindeer isn't just hard work - it can be fatal. Swedish researchers have compiled a list of the most dangerous jobs in the Scandinavian country of nine million and found that ...

Reindeer are known for pulling sleighs and having shiny, glowing noses that light up the night. Rudolph the Red-nosed Reindeer may be a work of fiction, but there is surprisingly some truth behind ...

Reindeer's hairy snouts were, on average, 25 percent more densely packed with tiny blood vessels, or capillaries, than those of their human counterparts. More than 70 years after the publication ...

Thus, eight reindeer trying to fly through a foggy night would be flying blind. However, red light — just like the light emitted from Rudolph’s nose — travels farthest through fog.

And in normal light, reindeer can have a pink coloration on their noses. “We found that Rudolph, indeed, has a red nose, but that it is completely related to his normal physiology,” Ince said.

When the technique was applied to two reindeer noses, the researchers found a 25% higher density of blood vessels, carrying a super-rich concentration of red blood cells.
