Oh snap. Quick dental rhyme:
In order to keep those cavities away
"Flush" your teeth at least twice a day
Helloooo, turkey time how are you! yes? turkey time?
AN early happy thanksgiving to you since I don’t update thursdays.
Everybody poops! Animals poop, people poop, and the bacteria in your mouth poop too!
Some of the germs in our mouths love sugary foods as just much as we do. When they metabolize the sugar they poop acid. That acid can wreak havoc on your teeth.

Humans Can Be Dated Like Trees
Like rings on a tree, human flesh can be dated in a consistent, reliable way. And as Trace tells us, this discovery could revolutionize medicine, and even enable us to extend life.

Irene Joliot-Curie (1897 – 1956)
Physics and Chemistry
The daughter of Marie and Pierre Curie, Irene Joliot-Curie is a notable scientist in her own right, winning a Nobel Prize in Chemistry with her husband, Frédéric Joliot-Curie, in 1935 for the discovery of artificial radioactivity, making the Curie family the most Nobeled family in history and a significant scientific dynasty.
A Black Hole’s ‘Point of No Return’
The most distinguishing feature of the supermassive black hole: its event horizon. The point of no return for in-falling matter, it is about 15 million kilometres across, or one-tenth of the distance between Earth and the sun - minuscule in astronomical terms.
In general relativity, an event horizon is a boundary in spacetime, most often an area surrounding a black hole, beyond which events cannot affect an outside observer. Light emitted from beyond the horizon can never reach the observer, and any object that approaches the horizon from the observer’s side appears to slow down and never quite pass through the horizon, with its image becoming more and more redshifted as time elapses. The traveling object, however, experiences no strange effects and does, in fact, pass through the horizon in a finite amount of proper time.

Natural Selection by Noah Scalin
Scalin on his project:
The Natural Selection portrait series specifically explores the lives of great scientists whose work has had an incredible impact on the world. Each diptych is made up of the portrait of a deceased scientist and a representation of his/her skull. The skull is made by literally rearranging the elements used in the portrait, thus destroying that original creation in the spirit of the traditional sand mandalas of Tibetan Buddhism. The scientists represented are all great thinkers whose creations had an impact on our lives today, but also serious repercussions for their own lives (and deaths).
Well … these are pretty dang brilliant.
