There are few places on Earth as isolated as Trindade island, a volcanic outcrop a three- to four-day boat trip off the coast of Brazil.
So geologist Fernanda Avelar Santos was startled to find an unsettling sign of human impact on the otherwise untouched landscape: rocks formed from the glut of plastic pollution floating in the ocean.
Santos first found the plastic rocks in 2019, when she traveled to the island to research her doctoral thesis on a completely different topic—landslides, erosion and other “geological risks.”
She was working near a protected nature reserve known as Turtle Beach, the world’s largest breeding ground for the endangered green turtle, when she came across a large outcrop of the peculiar-looking blue-green rocks.
Intrigued, she took some back to her lab after her two-month expedition.
Analyzing them, she and her team identified the specimens as a new kind of geological formation, merging the materials and processes the Earth has used to form rocks for billions of years with a new ingredient: plastic trash.

“Bats have attracted great attention as a likely reservoir of the SARS-CoV-2 virus responsible for the COVID-19 pandemic,” says Professor Wang Lin-Fa of the Duke-NUS Emerging Infectious Diseases (EID) Programme and senior author of the study in the journal Cell. “But this unique ability to host yet survive viral infections could also have a very positive impact on human health if we can understand and exploit how they achieve this.”
The research is focused on multi-protein complexes called inflammasomes that are responsible for the overactive inflammation that causes serious symptoms in many diseases. Inflammasomes are also implicated in functional decline in aging.
The researchers discovered that a bat protein called ASC2 has a powerful ability to inhibit inflammasomes, thereby limiting inflammation.
“This suggests that the high-level activity of ASC2 is a key mechanism by which bats keep inflammation under control, with implications for their long lifespan and unique status as a reservoir for viruses,” explains Matae Ahn, first author and co-corresponding author of the study and an adjunct research fellow with the EID Programme and the SingHealth Duke-NUS Medicine Academic Clinical Programme.

This is super interesting and discusses how tilling soils destroys the microbiome of soil, with some micro fauna and microbe populations not even fully recovering in disturbed soils for upwards of 10 years.
That's why the best ways to improve soil is through top dressing with mulch!
