Throughout this week we'll be catching you up on the news you might have missed over the Christmas break. Next up: giraffes, hadron colliders, and space... Did you know that water may have two liquid states? Or that a weasel temporarily shut down the Large Hadron Collider at Cern in Switzerland? Here are some of the impressive science facts we learned in 2016: 1. The Earth’s technosphere – which basically comprises of all the human-made things on this planet – weighs 30 trillion tons – a mass greater than 50 kilos for every square metre of the planet’s surface. 2. The world’s smallest snowman is less than three microns tall. For comparison, a typical human hair is approximately 50 microns in diameter. 3. Humans lost their penis bone – called the baculum – around 1.9 million years ago, when the species became monogamous during the time of – you guessed it – Homo erectus. 4. Cod may have regional accents and scientists are currently researching whether the same applies to bees. 5. There are actually four species of giraffes. Scientists have categorised them as the southern giraffe (Giraffa giraffa), the Masai giraffe (Giraffa tippelskirchi), the reticulated giraffe (Giraffa reticulata) and the northern giraffe (Giraffa camelopardalis). 6. Scientists found a Greenland shark that’s around 400 years old, making it the longest-living vertebrate on Earth.
