Aaaand I’m back! Kicking off the week with a little zebra finch griffin, in honor of my research species and my school’s very very new mascot.
I knew I would be busy but I still think I underestimated!!!

This is Alexandrite, it’s also called “emerald by day, ruby by night”
It changes colour based on whether the light source is from the sun or from a candle.
It does this because Alexandrite strongly absorbs yellow light due to chromium ions in its crystal structure, leaving the other colours behind. Light from the Sun emits all colours, but it peaks in the green, and our eyes are most sensitive to green, so in Sunlight Alexandrite is green.
Incandescent lights are things like candles and filament light bulbs. They also emit all colours of light, but they peak far, far into the red, so there’s not nearly as much green or blue, so under those, Alexandrite is red. 
Gemstones are awesome.

Found in a field belonging to the Vallo Diocese estate, a Viking Age circular fortress rewrites the Danish history books. It is the fifth construction of its kind found in Denmark, but the first such discovery in sixty years, reports Politiken.

“It’s great news!” Lasse CA Sonne, a Viking Age historian from the Saxo Institute at the University of Copenhagen, told the newspaper.

“Although, there were Vikings in other countries, these circular fortresses are unique to Denmark. Many have given up hope that there were many of them left.” Read more.
