TIL that Will Ferrell was at home watching a documentary on one of the first women to anchor news telecasts when her former coworker appeared on a screen. He reminisced: ‘You have to remember, back then I was a real male chauvinist pig. I was not nice to her.’ This was the inspiration for Anchorman.

TIL That in 2014, the Danish government created the entire country of Denmark in Minecraft. It was then promptly blown up by users and had American flags planted on the ruins.

The Danish Geodata Agency recently recreated the entire country of Denmark in Minecraft at a 1:1 scale. It’s one of the biggest Minecraft creations ever, made up of about 4000 billion brick and 1 terabyte of data. It was ingeniously built using the agency’s 3D elevation model and was meant to be used as a teaching tool.

Of course, players almost immediately began blowing it up.

They weren’t supposed to be able to. The Danish Geodata Agency disabled the ability to use dynamite but neglected to disable the minecart with dynamite item. According to The Register, players discovered this, set off explosives in several Danish towns, and built American tanks and flags on top of the ruins.

“We consider that as a nature of playing Minecraft – elements are broken down and new are being created,” Danish Geodata Agency spokesman Chris Hammeken told The Register. “Therefore we will not reboot the demonstration of Denmark in Minecraft. But occasionally we will rebuild minor areas if buildings are removed and nothing new is being created.”

You can download the Denmark map in sections from the Danish Geodata Agency’s website. So far it’s been quite popular, with over 200,000 downloads.

“We are very happy to see so many players around the world creating fancy nice things and have fun,” Hammeken said.

TIL Buzz Aldrin is the oldest person to ever reach the South Pole, visiting in Nov. 2016 at the age of 86

Buzz Aldrin said he was evacuated from the South Pole last week because he became short of breath and began showing signs of altitude sickness.

The 86-year-old adventurer, who was the second man to walk on the moon, released details Sunday of his dramatic medical evacuation from Antarctica. He is continuing to recuperate in a hospital in Christchurch, New Zealand.

Because of the thick ice that blankets Antarctica, the South Pole sits at an elevation of 9,300 feet.

Aldrin said in a statement that he still has some congestion in his lungs and has been advised to rest in New Zealand until it clears up and to avoid the long flight back to the U.S. for now.

Aldrin, his son Andrew and manager, Christina Korp, had been visiting Antarctica as tourists on a trip organized by the White Desert tour company. They left last Tuesday from South Africa. “South Pole here I come!” Aldrin wrote on Twitter at the time.

He said the trip began well and that he’d been planning to spend time with scientists who were studying what it would be like to live on Mars because the conditions in Antarctica were similar.

TIL Beaver’s teeth are fortified with iron, which causes the orange coloring and allows them to “chew” the wood.

Beavers don’t brush their teeth, and they don’t drink fluoridated water, but a new Northwestern University study reports beavers do have protection against tooth decay built into the chemical structure of their teeth: iron.

This pigmented enamel, the researchers found, is both harder and more resistant to acid than regular enamel, including that treated with fluoride. This discovery is among others that could lead to a better understanding of human tooth decay, earlier detection of the disease and improving on current fluoride treatments.

Layers of well-ordered hydroxylapatite “nanowires” are the core structure of enamel, but Derk Joester and his team discovered it is the material surrounding the nanowires, where small amounts of amorphous minerals rich in iron and magnesium are located, that controls enamel’s acid resistance and mechanical properties.

Enamel is a very complex structure, making a study of it challenging. Joester’s team is the first to show unambiguously that this “amorphous,” or unstructured, phase exists in enamel, and they are the first to show its exact composition and structure.
