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.”

Heart Implants, 3-D-Printed to Order

Just right: An array of sensors is embedded in a material designed to fit a beating heart perfectly.

3D Printing Human Organs

Video and article from CNN on the future of 3D printing and biomedical engineering!

So I just want to make a quick post to remind all of you studying engineering that this is a challenging field. There might be times where you doubt yourself but hang in there. There is also a very rewarding future ahead of you.

Women in Science Interactive

Women in Science, a new interactive tool, presents the latest available data for countries at all stages of development. Produced by the UNESCO Institute for Statistics, the tool lets you explore and visualize gender gaps in the pipeline leading to a research career, from the decision to get a doctorate degree to the fields of research women pursue and the sectors in which they work.

Do you guys take anatomy lessons?

Actually this next semester I am taking my human anatomy class!

In regenerative medicine breakthrough, lab-grown human heart tissue beats on its own
Although this is not the first case of biomedically engineered heart tissue, the team from University of Pittsburgh was able to do it form induced pluripotent cells (the recent nobel prize for medicine). They were able to use induced pluripotent cells derived form human skin cells to create a heart cell. It was then placed on to a stripped mouse heart, where it was able to differentiate into a functional organ beating on its own. They were able to get it to beat 40-50 beats per minute!
Although a fully functioning human heart still requires many more parts refined, this is one step closer to a breakthrough in cardiology!

I’ve seen this photograph very frequently on tumblr and Facebook, always with the simple caption, “Ghost Heart”. What exactly is a ghost heart?
More than 3,200 people are on the waiting list for a heart transplant in the United States. Some won’t survive the wait. Last year, 340 died before a new heart was found.The solution: Take a pig heart, soak it in an ingredient commonly found in shampoo and wash away the cells until you’re left with a protein scaffold that is to a heart what two-by-four framing is to a house.Then inject that ghost heart, as it’s called, with hundreds of millions of blood or bone-marrow stem cells from a person who needs a heart transplant, place it in a bioreactor - a box with artificial lungs and tubes that pump oxygen and blood into it - and wait as the ghost heart begins to mature into a new, beating human heart.Doris Taylor, director of regenerative medicine research at the Texas Heart Institute at St. Luke’s Episcopal Hospital in Houston, has been working on this— first using rat hearts, then pig hearts and human hearts - for years.The process is called decellularization and it is a tissue engineering technique designed to strip out the cells from a donor organ, leaving nothing but connective tissue that used to hold the cells in place. This scaffold of connective tissue - called a “ghost organ” for its pale and almost translucent appearance - can then be reseeded with a patient’s own cells, with the goal of regenerating an organ that can be transplanted into the patient without fear of tissue rejection.This ghost heart is ready to be injected with a transplant recipient’s stem cells so a new heart - one that won’t be rejected - can be grown.(Source)
