Blue Lava!!

I found this article called “Indonesian Volcano Erupts Electric-Blue Lava” by Robin Andrews. This is color is created when the lava burns the surrounding sulfur. The images shown are very cool! I wish I could visit these places.

The closest I can get to lava is the fire pit I have in my open patio.

Maybe I’ll look into safe ways to change the color of the flames. As exciting as it would be to have multi-colored flames, I do not want to cause unintended fumes….

Prosthetics and Skin Sensors

About a year ago, I read “‘Digital skin’ activates brain cells” by Jonathan Webb. This article is about a polymer that contains sensors. When the sensors detect pressure, they send electrical signals. The researchers connected these sensors to a sliver of rat brain and were able to observe a different rate of pulses when applying various pressures. The idea is to develop this technology enough that it can be added to prosthetic limbs. The material is already thin enough that it can bend easily to act as a skin covering.

As I read the article, my mind kept flashing back to the scene in Star Wars where Luke’s artificial hand is pricked and we can see a flinching reaction.

Today, I watched a CNN video, “Great Big Story: For Amputees, Reactivating the Sense of Touch” about adding similar sensors to prosthetic limbs. It is an amazing and uplifting video.

I’m glad people are working in these areas. Every step of progress means more help for people who lost a limb or are born without one. I wish everyone the best of luck in finding a solution.
