The largest canyon system in the solar system is still active and shaping Mars today, billions of years after it first formed, finds new research by scientists at Imperial College London and Columbia University, including Folarin Kolawole, a structural geologist at Lamont-Doherty Earth Observatory.

Unlike Earth, Mars doesn’t have a system of moving tectonic plates that continually creates and reshapes major fault zones. Instead, its outer shell behaves more like a single, slowly cooling lid.

“This makes our new results particularly important as Mars gives us a very different natural experiment. It shows that on a planet without plate tectonics, structures created billions of years ago can remain important and still control where the crust breaks today,” says Kolawole.

Plastics are supposed to be chemically inert. It’s the reason they’re used so frequently to package food, bottle water, and create children’s toys.

But something important happens when a large piece of plastic fragments into micro and nanoparticles: its surface area increases dramatically, exposing vastly more of the material to its surroundings.

A new study by researchers from Columbia University and the University of California, Berkeley found that this newly created surface is not necessarily safe and identified the chemical reasons why.

“This work has significant implications for environmental and human health. Microplastics and nanoplastics can form and enter aquatic environments through discharges from sources such as plastic manufacturers and laundromats,” says co-author Beizhan Yan, an environmental geochemist at Lamont-Doherty Earth Observatory.

“Various uses and processes in our daily lives can also generate microplastics, including microwave heating, sunlight exposure of bottled water during storage, and IV injections in healthcare settings. This foundational work provides a potential pathway for understanding their health impacts,” adds Yan.
