London: Scientists have unravelled the mystery behind the
glowing red nose of Rudolph, the lead reindeer pulling Santa's
sleigh on Christmas Eve. Scientists say Rudolph's nose shines so
brightly because it is richly supplied with red blood cells
which help to protect it from freezing and to regulate brain
temperature. This superior 'nasal microcirculation' is essential
for pulling Santa's sleigh under extreme temperatures, the
'Daily Mail' reported. Tiny blood cells known as micro-vessels
in the nose are vital for delivering oxygen, controlling
inflammation, and regulating temperature, the scientists claim.
Norwegian and Dutch researchers knew how important this
regulation is for flying reindeer, especially as they take to
the skies from their frozen home near the North Pole. They set
out to test whether Rudolph's famous red nose was Scientists
