Happy Holidays everyone! To celebrate the holidays, the ending of this year, AND the end of finals...I have two facts!

1) Did you know there is a toad who carries eggs IN her back? The female surinam toad carries the fertilized eggs on her back. They fuse into her skin forming little pockets, where the tadpoles then hatch and mature in. When the little guys finally develop into toads, they swim out of their mother's back. Some people find this a little creepy, but I think it's cool.

2)Did you know that newborns aren't bathed as soon as they're born? When a baby is born, there is this white coating called vernix. This layer forms during pregnancy and provides a barrier against the fluids in the uterus. After birth, it acts as antioxidant, skin cleanser, moisturizer, temperature regulator, and safe antimicrobial for the baby. Washing it off not only causing the baby's skin to dry, but it also allows for microorganisms to immediately begin colonizing...and some we don't want.

Did you know that Koreans celebrate the Winter Solstice (Dongji) with red bean porridge? Dongji (동지) is a celebration of the longest night of the year. After this day, the hours of daylight will begin to increase. A sign that spring is coming! So they make patjuk(팥죽), which is made of red beans and rice flour dumplings called saealshim (새알심). Oooo! I want to try some!

Did you know slugs can eat the Portuguese Man of War? The sea swallow (also known as Glaucus atlanticus) is a small sea slug that feeds on the colony. The sea swallow consumes the venomous tentacles and stores the poison in sacs on the tips of its cerata (finger-like projections). Because of that, the venom becomes concentrated allowing the slug to deliver an even more painful sting than the Man of War. Ouch!

Did you know that male gentoo penguins can propose to females using stones? These penguins actually build their nests from a large circular pile of rocks. The rocks are carefully guarded and disputes over good ones are quite common. (Unfortunately I don't think we can use engagement rings to build houses...though we could use them to buy houses. :P)

Did you know that some people with two different colored eyes may have Waardenburg syndrome? This condition is the result of a genetic mutation. It is autosomal dominant. Individuals with the syndrome may have hearing loss in one or both ears. They also may pale blue eyes or two different colored eyes. Another common trait is a patch of white or gray hair. However these traits vary from individual to individual. Thanks to Stef Sanjati, a Youtuber, for her video.

Did you know that you could make a desert out of pandan leaves? (In Bangladesh, pandan is called ketaki.) The pandan plant looks more or less like grass. However it is widely used in Southeast Asian cooking as flavoring. In fact, it can be used for rice dishes, cakes, and drinks. What do I want to try? Thai pandan custard! This lovely green custard is made from pandan leaves, coconut milk, cream, sweetener, and eggs. However until I can find a place that serves the custard, I'll settle for some pandan ice cream. I've been putting off my trip to the Chinatown Ice Cream Factory...

Did you know that the material in an atheroma is mostly macrophages (white blood cells)? When a person consumes a high amount of cholesterol, it can trigger an inflammatory response within the intima, the inner wall of an artery. White blood cells attempt to digest the cholesterol and become foam cells. The foam cells then die and release their contents along the artery wall, forming the atheroma (deposits along an artery's wall). The material hardens into a plaque, leading to a narrower lumen and higher blood pressure.
