A cool read on stable isotopes being used as a means of tracking migrating animals. This method is an upgrade from using tags, as there is less capture points.

Another article just highlighting PFAs, how they affect us and a few ways to mitigate it.

PFAs are forever chemicals that don't breakdown in the environment or in our bodies.
Unfortunately the damage has been done but we can prevent further damage by using PFAs-free products or limiting exposure for example.

Think your home is free from PFAS forever chemicals? Think again https://t.co/v1JryRO1NU

These bugs can be used as indicator species due to their nature of up taking heavy metals in soil. However, this is not a solution in getting rid of the metals, as according to the article, the metals can still find it's way up the food chain. https://t.co/q5oXxx6J5X

I used to play with these guys as a kid. They are Oniscidae or also called Cochineal. We just called them pill bugs. They're actually from a prehistoric family of isopod crustaceans whose function is to remove harmful heavy metals from the earth such as mercury, cadmium, and lead. They're good bugs. Be nice to them.

Analysis of PFAS present in blood samples. This is a helpful study as PFAS are forever chemicals, so its exposure levels can be determined, along with its effects and how this can be mitigated.

Thermal infrared satellite images don’t just make for nice pictures. They also give us quantitative information about surface temperatures. The heat is on in this week’s #Yellowstone #CalderaChronicles!
