Recent Academy News

April, 2025

A number of our sections (including Entomology, Geology, Herpetology, Ichthyology) were present at the Earth Day celebrations at Forest Park Nature Center in Peoria Heights, IL. Our entomology section website has a number of photographs of the event. They presented this as part of their outreach activities.

We held our 2025 banquet on April 18, 2025 at Barrack’s Hospitality Group Banquet Center in Peoria, IL. Sheldon Schafer was our guest speaker. He spoke on the topic of archaeoastronomy [the study of the astronomical knowledge of prehistoric cultures, based on inferences from their archaeological remains.].

Science Tidbits

We frequently encounter articles and news regarding science. We thought that we would begin sharing these articles (with a little commentary). Hence, the name – science tidbits. We will try to arrange these by date (with the most current on top).

We enjoy reading your comments. This is the easiest way for us to know we are supplying information you want. Make certain you click on any of the linked articles (usually with a title of Week of…). Once you have the specific post open, you should see a comment area near the bottom.

We plan to periodically update these tidbits moving forward, but not as frequently as we have not been receiving many comments and insights from visitors. We really need to know what you find interesting.

Anthropology

Ancient Megalithic Structure Older Than The Egyptian Pyramids Discovered In The Peruvian Andes. “Dated to around 2,750 B.C., using radiocarbon dating techniques, the circular stone plaza was built using massive vertical stones placed in upright positions. This construction method is similar to other ancient sites from the ancient world, like Stonehenge, which is approximately the same age as the newly discovered stone plaza. However, the researchers say it is a construction style “previously unseen” in the Andes.”

Astronomy

Life on Mars could have thrived near active volcanoes and an ancient mile-deep lake. “…crustal changes behind these newly discovered volcanic features are analogous to a step that Earth took on its own evolutionary pathway toward plate tectonics more than 2.5 billion years ago.”

Did you know that today is the birthday of two very influential 19th century personas? Ok, Abraham Lincoln was born on this day in 1809. Who else – Charles Darwin was also born on this day in 1809. Yes, they share the same birth date. Here are the articles we found interesting this week. We try to keep these articles in categories related to existing sections of our Academy.

Anthropology

For those who don’t know – “Euglenids are a group of unicellular eukaryotes that gain energy through both photosynthesis, like a plant, and through consuming other beings, like an animal.” This seems like the sort of article one should review in celebrations of Darwin’s birthday today.
Life on Earth may have first sparked in shallow “soda lakes.” “The emergence of life requires high phosphate concentrations, far exceeding those found in natural water bodies like rivers, lakes, or oceans.”
