Through science, we learn how incredible our story truly is. It’s a story that’s literally been written in the stars. It’s a story that is still unfolding. And it’s a story that every single one of us is a part of.

Science Fiction Becomes Science-Fact: Two Strategies for Repairing Humans
Not long ago, it would have sounded like science fiction to discuss growing human organs in the lab or re-writing DNA. Yet today both are realities that will change the world and allow for longer and healthier lives.
Already, lab-grown bladders, windpipes and blood vessels have been successfully created and implanted into humans. Most recently, tissue engineering pioneer Dr. Anthony Atala and his team at the Wake Forest Institute for Regenerative Medicine announced another breakthrough: lab-made vaginas—one of the most complex organs made to date. In four girls with MRKH syndrome, a medical condition in which the vagina and uterus are underdeveloped or absent, Dr. Atala’s team was able to create new organs that functioned normally, dramatically increasing each patient’s quality of life.
Image overload: Help us sort it all out, NASA requests
NASA is asking for your help.
No, you do not get to go to space.
You do, however, get to view hundreds of thousands of images taken from space. Via The Gateway to Astronaut Photography of Earth, NASA is making available images ranging from the Mercury missions of the 1960s to photos recently snapped from the International Space Station.
The hope, NASA says, is that the images “could help save energy, contribute to better human health and safety and improve our understanding of atmospheric chemistry. But scientists need your help to make that happen.”
