I am a doctoral student at Arizona State University interested in the interactions between microbial life and sediments, biomarkers of past life preserved in the geologic record, and the exploration of Mars and other astrobiologically-relevant targets.

To maximize crop yields on Mars it would be advantageous to do away with annuals and biannuals by engineering the latter into perennials as standard. Not only would that entail far less work to grow produce as the act of replanting is made obsolete, but per given cultivated area perennials bring forth more food and materials with less demand from the soil than the equivalent of annuals.
Imagine a superfood annual such as lentils engineered into a lentil tree for which there already…
I just read the piece at the link below entitled "Study: Life might survive, and thrive, in a hydrogen world."
I'd been thinking on similar lines recently, on different atmospheres with early life, but I was considering anoxogenic bacteria whose byproduct is sulfur instead of molecular oxygen. ¿Had life evolved on Venus could its sulfuric clouds be the signature byproduct of such life with no branches ever evolving to produce the equivalent of Earth's Great…
Let me first say Hi to everyone as a new member here! I hope you are all safe, sound, and not too stir-crazy during this Pandemic.I recently stumbled upon a notion for SETI which seems so simple I…Continue
If your 10-12 yr old child is interested in space science, I would like to invite them to our courses. I am a former science teacher, mom of three, and a former NASA astronaut instructor. I also…Continue
