I'm Aaron, an environmental geology major from Houston. I do research in planetary geology and in my spare time I study sustainable development.
For fun, I dabble a bit in fiction writing, video game editing, multimedia programs, and following science news.
I love science because it provides me with a sense of wonder towards the world around me...it makes me feel alive!

Fox News talks about working mothers’ negative impact on their children. AKA “When Fox News gets so misogynistic that their own anchor is 1026% done with them.” [x]
Located in Hamelin’s Pool, a shallow area of Shark Bay in Western Australia, these odd formations aren’t rocks—they’re stromatolites, and they were built over millennia by single-celled cyanobacteria (also known as blue-green algae). 4,000 to 6,000 years ago, a huge bank of seagrass began to block the tidal flow into Hamelin’s Pool, which meant that the water became twice as salty as the open ocean. Animals like snails and chitons that would usually feed on the algae couldn’t survivd, so the blue-green algae began to flourish. Gathered in colonies, they trapped sediment with their sticky surface coatings. This sediment reacted with calcium carbonate in the water and formed limestone, essentially creating a living fossil—this limestone is alive, its top surface layer teeming with active cyanobacteria. The limestone builds up slowly at a rate of about 1mm per year. The stromatolites in Shark Bay are estimated to be between 3,000 and 2,000 years old, but they’re similar to life forms in Precambrian times, 3.5 billion years ago, at the dawn of complex organisms. There are over 50 kinds of cyanobacteria in Shark Bay, and one is thought to have descended from an organism that lived nearly 2 million years ago, making it a part of one of the longest biological lineages.

Life found in the muck of Antarctic lake
Researchers grew 20 cultures of microbes found in the uppermost layer of the sediment core of Lake Hodgson that could give insight into how life formed on Earth.
