After reading about gender-bias and conversation dominance in the classroom, I asked for a peer to observe a physics class I was teaching and keep track of the discussion time I was giving to various students along with their race and gender. In this exercise, I knew I was being observed and I was trying to be extra careful to equally represent all students―but I STILL gave a disproportionate amount of discussion time to the white male students in my classroom (controlling for the overall distribution of genders and races in the class). I was shocked. It felt like I was giving a disproportionate amount of time to my white female and non-white students.

Even when I was explicitly trying, I still failed to have the discussion participants fairly represent the population of the students in my classroom.

This is a well-studied phenomena and it’s called listener bias. We are socialized to think women talk more than they actually do. Listener bias results in most people thinking that women are ‘hogging the floor’ even when men are dominating.

Stop interrupting me: gender, conversation dominance and listener bias, by Jessica Kirkpatrick from Women In Astronomy

Implicit bias is a thing, just like privilege. Calling it out isn’t meant to shame anyone, but to alert us to step it up and improve ourselves so everyone can have a voice. Be conscious of what you and others are saying, and know when not to speak.

So I have one white male student in all of my classes, and he is my worst. However, I am constantly telling him to get to work and to stop harassing other students, so I guess he does get more attention than the rest.

From Natural Selection

"While these organised structures might look like the work of an artist, they’re actually just the remnants left behind where a sand bubbler crab’s been snacking. 

During low tide they exit their burrows (as seen in the top pic) to scour the sand for tiny bits of organic debris in a radial motion. While eating, the crabs ball the excess sand on their heads, then discard it when it gets too big for them to see over, leaving behind a remarkable-looking reminder which helps them keep from searching for food in the same sand twice.

Each time High Tide returns, the small structures crumble and are washed away, all while leaving behind more food particles to fuel the tiny crab’s next accidentally artistic pursuits.”

The first time I held a human brain in Anatomy Lab I was completely speechless. I looked at my classmates expecting a similar reaction and they looked back at me confused like…”dude let’s start identifying the structures.” I had to take a step back and let it process…in my hands was someone’s entire life. From start to finish, every memory, every emotion, every bodily control…was right there in my hands.

Today is September 4th 2014. It has now been 8 years since the death of one of my greatest heroes.Steven Robert Irwin. In that time, and unlike what my comforting mother, and friends assured me, it has not become easier. In the years since his passing I have watched as animal media feed into the hands of the uneducated, sensationalist, and often even cruel TV show hosts only content in showcasing the brutality, and deadly aspects of wildlife. I have seen no one step up to the plate, no one fill that void he left in the world. Consider this an open letter, to all those as tragically in love with the natural world as I. Get out there, be loud, show your self and your love to the world, educate, experience, and just and just freaking live. We are but one species on what may be the most biodiverse planet in the universe. So get up, and make some damn noise, lose the fear, and show them what you love.
       "Because people want to save the things that they love."
             We all miss you mate.

WHAT KIND OF WIZARD FISH IS THIS

DUDE THATS A BABY KAIJU

pew, pew!

SCIENCE SIDE OF TUMBLR URGENT

YOU CALLED!?
This fish is not actually spitting bioluminescent spit…it’s spitting out its bioluminescent food! Some clever scientist has put some bioluminescent ostracods in a tank with some little fish. When agitated, these ostracods (tiny shirmpthings) secrete chemicals that, when combined, emit light.
Why?
You’re seeing why right here. Just before the fish spits it out, those light chemicals are filling up the belly of the fish. Now, it isn’t poisonous or anything…but the fish wants NOTHING TO DO WITH THEM because the fish has predators too. 
So yeah, if you’re a little fish and suddenly you’re FREAKING GLOWING, your lifespan has just gotten a lot shorter. 
As soon as the fish realizes that there’s light emanating from its belly, it pukes out the glowing juices (and the little shrimp). You can actually see the ostracod in this gif swimming away down toward the bottom of the tank happy as a clam…or a shrimp. 
Evolution is AWESOME.
