Crocodiles vs. Alligators

If you’re staring imminent death in the face, it’s best to know which genus and species is staring back. Sadly, does not feature actual footage of crocodiles versus alligators, but I’ll let that slide.

Also, The Brain Scoop got a makeover! Do you love it? I love it. A great show just got greater. We’re all gonna have to step up our game to keep up with you, Emily

This is Your Brain on Engineering (GoldieBlox Easter PSA)

At age 2, girls start to identify with their gender. Or, more accurately, all kids start to understand that they have a gender, and become more aware of the social influences for how they should act as a result. In our culture, there are narrow blueprints called “boy” and “girl” that dictate to us all what is and is not the “right” way to act. These blueprints are pretty limiting — “boys don’t cry” and “girls are princesses” aren’t exactly the greatest life mottos. Gendered influences come from everywhere around kids: their parents, their friends, their teachers, the games they play, the movies they watch, the books they read… the list is endless, and all of it sends a message, sometimes negative and often limiting, about what is and isn’t a “girl thing” or a “boy thing.”

Voodoo Dolls Prove It: Hunger Makes Couples Turn On Each Other (NPR) 
A lot of us know what can happen when we get hungry. We get grumpy, irritable and sometimes nasty. There’s even a name for this phenomenon: “Hangry, which is a combination of the words hungry and angry,” says psychologist from Ohio State University.
Bushman recruited 107 couples to study the relationship between blood sugar levels and anger. He assessed the quality of their relationships and taught them how to measure their blood sugar. Then he sent each volunteer home with something unusual: a voodoo doll and 51 pins.
After three weeks, Bushman and his team assessed the damage done to each doll. Volunteers who had low levels of blood glucose stuck more pins in the voodoo dolls than those who had high levels of blood glucose, Bushman and his team reported  Monday in The Proceedings of the National Academy of Sciences.

If Earth’s water were drained into a single drop, it would measure about 950 miles in diameter. Roughly three percent is fresh water, and just one-third of that is easily accessible. Meeting the growing need for water is a critical challenge. Many countries rely on desalination to produce fresh water, but current techniques are typically energy-intensive, using enough energy globally to power nearly seven million homes. That’s why today GE is launching an open innovation challenge to improve the energy efficiency of water desalination. Find out more about the challenge here. GIF by Julian Glander and based on data from Woods Hole Oceanographic Institution.

GE you put that water back right now, you hear me? We need that.

EXCERPTS  >|< Your Body During Adolescence (1955)

A video from Prelinger Archive.

A series of gifs excerpted from Your Body During Adolescence. Shows the seven glands that regulate human life and growth with emphasis on the pituitary and sex glands. Outlines changes that take place in the bodies of boys and girls.

Do you really know your body? From the age of 12-15, you’re basically just a rapidly expanding bag of glands (according to this video, anyway, which you can watch in full below):

Yes, it’s a funny look back in time. But sadly, 60 years later, this is still how many young people are introduced to sexual education, with sex only spoken about as a way to make babies, and adolescence only serving as a stepping stone to life as a responsible, working adult (who, of course, wants to get married and make babies). Adolescence is perhaps the most crucial period of a person’s life, in which you experiment and question and discover and change all sorts of things about your mind and body. Yes, in the end you become an adult, but instead of the mythical and somber suit/tie/apron/job/baby definition put forth in these antiquated videos, you should consider being an adult as becoming just a slightly older person who experiments and questions and discovers and changes all sorts of things about their mind and body.

For a look at how sex ed should be done, you really should be watching the Sexpalantions channel with Dr. Doe on YouTube!! Appropriately, here is her video “Sex is Not Black and White”:
