Life in Plastic: Not Fantastic
Organic debris in the ocean clumps with microplastic bits; together, they drift like snowflakes to the seafloor. Sabrina Imbler writes for The New York Times about how understanding the microplastic snow is vital to knowing how long the particles stay in ocean waters before settling at the bottom. Among the bits of organic matter hitching themselves to microplastics are plastic-eating microbes. In 2018 Elizabeth Svoboda interviewed plastisphere expert Maria Luisa Pedrotti for Quanta about the new ocean ecosystem fueled by plastics.


Heart of Darkness
Evidence for dark matter was first found in the 1960s, but what the unseen substance is remains a mystery. Chanda Prescod-Weinstein writes for Scientific American about the many proposals and attempts to learn about the elusive matter. The axion is gaining traction as a leading dark matter candidate. If axions exist, they should be produced in the cores of neutron stars. Dark matter hunters are now taking guidance from that tip as they look to the skies, Jonathan O'Callaghan reported for Quanta in 2021.
