Men and Women Ain’t So Different
Men are from Mars, Women are from Venus….or are they? Couldn’t we all just be from Earth? Finally science has produced evidence that supports what we already knew — the whole “men are from Mars, women are from Venus” trope is false. According to a new study from the University of Rochester, men and women don’t have such distinct psychological characteristics after all. Watch Laci and Trace as they delve into the classic gender debate.

Cells cultured along origami seams, prodded to self assemble into 3D shapes. Future applications include organ growth and drug delivery.
Awesome! If you missed this cellular origami technique a couple weeks ago, you can read about it in this post of mine from a couple weeks ago. On a side note, I’m always happy when people turn science into GIFs.
What Makes Cancer Cells Different?
We’ve talked before about how tricky a disease cancer is. Or, if you want to be accurate, how tricky a “set of diseases” it is. I mean, a single tumor is like a world unto itself, full of different populations of cells, each with their own individual set of mutations. That’s crazy to think about.
Cancer is the result of one of our cells’ most basic and core functions, cell division, gone awry. What causes it, in the large sense? How can we use cancer’s tricks against it to try and treat these diseases?
George Zaidan tackles those questions for TED-Ed in the video above. If nothing else, it’s the best combination of beans, fabric and cancer biology I’ve ever seen in a video. Goes nicely with my TED-Ed video on how the human genome is organized in the first place.
These snowflake-like crystals grow from tiny imperfections in floating sea ice, the super-frigid air causing water vapor to crystallize right out of the air into the stunning ordered shapes you see.
These “frost flowers” have been found to harbor microbial life, far more than the sea around them, creating tiny ecosystems like forzen coral. Life does find a way, huh?
Is The 5-Second Rule True?
I’ll go ahead and spoil the answer to that question and tell you no, it is not true.
But you won’t believe just how interesting the world of touching, not touching, and the shake-rattle-and-roll of molecular interactions can be. And when you find out how many little bacterial bugs are living on the things that you touch every day, you might decide to live in a plastic bubble for 2013. Great video from Vsauce.
How it feels to have a stroke
Neuroanatomist Jill Bolte Taylor had an opportunity few brain scientists would wish for: One morning, she realized she was having a massive stroke. As it happened — as she felt her brain functions slip away one by one, speech, movement, understanding — she studied and remembered every moment. This is a powerful story about how our brains define us and connect us to the world and to one another.
I don’t thing anything will beat those 20 minutes today.
