Space Village Grows in a Sleepy Border Town

Posted by Antonio Chaves on Tuesday, March 9, 2021, In : miscellaneous science news 
This story hits home for me because I have relatives in the Rio Grande Valley and visited it many times when I attended graduate school at Texas A & M. It is very exciting that a space center is going to be built in one of the poorest counties in the nation. Unsurprisingly, some retirees who live near the growing space center are opposed and do not want to move. Nevertheless, all of these are vacation homes and there are many coastal alternatives in the valley where they can live at a safe di...

Most Radioactive Places on Earth

This easy to understand video puts radioactive exposure in perspective by measuring it in terms of "bananas" (the radiation contained in a banana due to its potassium content). Much like the chart I referred to in an earlier post, this video puts many concerns to rest with regards to routine exposure like cordless phones and microwave ovens. I was particularly shocked at the amount of radiation absorbed by smokers. Would this be the main reason smoking causes lung cancer?

Electricity storage is a big dea

Posted by Antonio Chaves on Friday, July 19, 2013, In : miscellaneous science news 
I got this interesting chart from an article about how an energy storage company called Eos may revolutionize the way electricity is stored using zinc air batteries. I never knew that so much generating capacity was stored by simply pumping water! The advantage of these batteries is their low cost ($160 / kWh vs. $400 / kWh using lithium batteries). All of this is discussed in terms of making the grid more reliable. I wonder if these batteries are light enough to use in a vehicle?

Amazing Human-Powered Helicopter

Posted by Antonio Chaves on Sunday, July 14, 2013, In : miscellaneous science news 
The materials must be incredibly light because it is enormous. Its large size no doubt allows it to provide so much lift even though its propellers are moving so slowly:

About this blog

This blog was originally created in January 2013 to serve as a means for providing updates on science activities from the environmental science lab manual Ecology, Development, and Sustainability. I have now expanded its purpose to include other items of interest to science teachers.
