Capillaries spread throughout your entire body, carrying blood to every cell. Many are just large enough for a single red blood cell to fit through.

Disney Drone Parade
Drones make some people think of military and surveillance activities. And others wait for the day when drones will deliver our Amazon packages or our pizza order. But Disneyworld hasn’t been at the top of the “Cool Things Drones Can Do” list, until now.
Disney theme parks are well known for their rides, their friendly characters, the castle and their parades. The awesome displays of color and music and dancing require many stagehands, but this past month, Disney filed for three patents to use unmanned aerial vehicles in their parks. UVAs, more commonly known as drones, will completely revolutionize the park experience.
With UVAs, Disney Parks will have the ability to project images on drone lifted screens high in the sky. There are also plans to create giant sized parade puppets, manned solely by an army of drones (pictured above). And yet another patent suggests that Disney is working on virtual fireworks for their daily nighttime shows, saving lots of cost, and our planet!
The Federal Aviation Administration hasn’t approved drones for commercial uses yet, so it might be years before we have to say goodbye to the smell of firework bi-products.

Explainer Blog Team went on a trip to visit Tumblr HQ right here in NYC!
Here we have (from left to right going down):
Met some great people and got great insight into the world of Tumblr.
- bloggers are referred to as creators
- their office is filled with artwork created by tumblr artists
- they have the best break room filled with all kinds of yummy goodies
Thank you Tumblr, we had a blast!!
Valeria ( quetevala ) has been working at the New York Hall of Science for almost 10 years. Now she’s in college is studying to become a mechanical engineer. Although it is a male dominated field, Valeria is confident that she will succeed and inspire girls to get involved in STEM.
On Friday August 22, 2014 the Explainer Blog Team took a trip to Tumblr Headquarters! Having never gone before, we were all super excited to meet the staff and get some insight.
We met Katherine Barna, Betsy Cannon, Sarah Henochowicz and Janice Chang. These women told us about their backgrounds and how they attained jobs at Tumblr. It was super inspirational to hear their stories!
As a team we had many questions about how to create a more beneficial blog for our readers and we got a lot of advice that we are excited to use. Our tumblr experience was topped off with goodies and a tour of the Headquarters!
We look forward to planning a better experience for our readers and if you have any suggestions, please feel free to message us!
Science Needs Women:
For Women in Science; the L’Oreal Foundation
I’m sharing this video on any platform I can because when I first found it last week it had something like 1,400 views, but it’s the most beautifully produced and succinctly narrated video addressing some of the most complicated issues facing women in STE(A)M fields I’ve found yet.
I’m sharing this for every time I’m called a “feminazi.”
…for every time I’m told that my concerns aren’t valid, our that our issues are imagined.
…for every time I hear “women just don’t like science,” or worse - “women just aren’t good at science.”
…for every time we’re told that we can have a family or a career, but not both - and for every time we feel like we have to decide between the two.
…and because we need more women mentors in these fields to stand up for issues that are not “women’s issues” - these are people issues that affect our collective society as a whole.
The women in this video are my heroes and they should be your heroes, too.
Science needs women.
Important and inspiring.
Broken bones heal pretty well on their own. The only thing doctors really have to do is set the two pieces in line to ensure the bones grow back at the right angle. But certain injuries or defects leave too wide of a gap for new bone cells to fill in.
At Hogwarts, injuries like these would require Skele-Gro, the magical potion from the Harry Potter universe that’s known for it’s dreadful taste, and it’s ability to regrow “vanished or lost” bones. To regrow bones in the real world, our best technique been bone grafting. This process involves taking bone from a different part of the patient’s body and using it to fill in the gap.
This method doesn’t always work. Grafts don’t allow us to fit the complex shapes that bones come in, and sometimes the grafts don’t take. It’s still waiting on FDA approval, but thankfully, the newest method to regrow bone doesn’t involve a potion of any kind.
This idea relies on a biodegradable sponge seeded with human bone cells. Once the memory foam is formed into the proper size and shape, it is fit into the gap. It serves as a scaffold for the healthy bone to grow, but disappears once it’s replaced by solid bone.
It’s years away, but this biodegradable sponge could be a huge boost for reconstructive surgery.
