The Slytherin common room is located down in the depths of Hogwarts and reaches as far out as the lake. It’s darkly light with a greenish tint and while it may not be the warmest place, it is suppose to be one of the most relaxing rooms thanks to the sound of the water surrounding them. The entrance is through the dungeons and requires a password that is changed fortnightly and then pinned to the noticeboard inside. Upon entering you will notice the vast windows that offer a unique underwater view. The giant squid is amongst the many weird and wonder creatures said to frequently swim past. The rest of the room is appropriately decorated with skulls, leather sofas, dark wooden furniture and grand tapestries that cover the walls celebrating famous Slytherins throughout history.
If you are an adult, becoming an adult, about to become an adult, or are worried about becoming an adult. take the time to watch this
actually, I think everyone, everywhere would benefit from this. please take the time. life is hard. SIGNAL BOOST.
This is important. Imagine if all of Tumblr can see it. I don’t want notes I want for you to each have a better day then the last. boost. watch.
Watch this. it might change your life. reblog. spread the word.
This is so important.

Rear Admiral Grace Hopper would have been 107 today, and is being honored with a great Google Doodle. It’s quite literally impossible for us to imagine, as we sit here reading about her on the internet, but people used to use things like paper and pencils and chalk and slide rules to solve (and often not solve) complicated problems. Grace Hopper quite simply helped usher in the modern age, her impact, I think, is no less than the steam engine or the cotton gin.
Some awesome stuff she did: Grace Hopper developed first compiler, allowing computer calculations to move beyond simple arithmetic and into more complex problems. She also developed first standardized computer language, COBOL, which laid the groundwork for all the languages we use today.
One day she found a dead moth disrupting one of the electronic relays in the Mark 1 computer, and upon removing it (and fixing the computer), the term “debugging" was popularized (although the idea of computer "bugs" had been around before). Here’s her daily log from that day, with the offending moth taped to the page:
Beyond that, she was a charming scientific communicator, and she possessed a marvelous ability to make people, and mind you this was in a time when almost no one owned their own computer, truly appreciate both the importance and the complexity of computing technology.
She famously carried around a bundle of nanoseconds in her purse for illustrative purposes. Here she is charming the socks off of David Letterman, and giving him a nanosecond of his very own (don’t miss the picosecond joke, either) :
Rear Admiral Grace Hopper is single handedly one of the coolest people to walk this earth.
Ancient Human DNA Suggests Twisted Roots at Base of Human Family Tree
Scientists have sequenced DNA from the 400,000-year-old remains of an early human found in the Sima de Los Huesos cave in Spain. It not only shatters the record for the oldest human DNA sequence ever obtained, but is also forcing scientists to question what we thought we knew about human origins.
Traditionally, scientists have compared the measurements and proportions of these skeletons in order to place our ancestors along the human family tree and evolutionary timeline. The skeleton up top, from the Spanish cave, is classified as Homo heidelbergensis, a group of human relatives from Europe who, according to the bones, are thought to be the ancestors of Neanderthals.
But new and powerful DNA sequencing technology has given us the ability to stitch together sequences from older and more degraded DNA samples than we ever thought possible (I wrote about a 700,000-year-old horse sequence earlier this year for WIRED). The sequences in the Los Huesos DNA don’t agree with the old bone story.
The sequence shows that this 400,000-year-old DNA is most related to Denisovans, a group of early humans previously only found in Siberia (AKA “not near Spain”). It was also related to Neanderthals, which fits with the old idea, but suggests that there was a lot of interbreeding and migration going on in these groups, even before modern Homo sapiens had left Africa.
The genomic revolution is changing a lot about science, and the study of human origins is one of the fastest evolving (pun intended). This new info has confused the hell out of scientists, frankly, and there’s a lot of work to be done.
The roots of our family tree tell a twisted and gnarled tale, written in fragmented sentences, but modern technology is beginning to bring those lost words to light. Hopefully they aren’t jibberish.

Out of the night that covers me,
Black as the Pit from pole to pole,
I thank whatever gods may be
For my unconquerable soul.
In the fell clutch of circumstance
I have not winced nor cried aloud.
Under the bludgeonings of chance
My head is bloody, but unbowed.
Beyond this place of wrath and tears
Looms but the Horror of the shade,
And yet the menace of the years
Finds, and shall find, me unafraid.
It matters not how strait the gate,
How charged with punishments the scroll.
I am the master of my fate:
I am the captain of my soul.
Space: the Final Frontier. These are the voyages of the Starship Analytical. Our continuing mission: to seek out new methods and more square footage, to boldly go where Management refuses to go.
I just want to say that this is why minority representation in the media matters. Mae Jemison was inspired to become an astronaut after watching Nichelle Nichols as Uhura on Star Trek.
Media is NEVER “just” media.
It’s representation and perception too.
THIS BOOK IS INCREDIBLE
read it last night.
bought multiple copies for Xmas gifts. :)
This makes me so happy.

It’s that time of year again! Check out these incredible images of snowflakes under a microscope by Alexey Kljatov.
A happy Friday to our follows - each of them a unique snowflake!
Nature never ceases to amaze me.
