Very little is known about how plastic moves under the ocean's surface. But that's where 99% of it ends up, and scientists are trying to model how it flows.
Very little is known about how to properly reuse medical masks to fight infectious diseases, but some best practices are starting to emerge.
Homemade cloth masks aren't ideal, but given the present shortages of medical-grade protective gear in the midst of a pandemic, they may be the best option for some people.

As the universe cooled in the era after the Big Bang, a supermassive black hole had already formed in the center of a galaxy, forming a giant engine of energy we can still see today.
Something's up with the North Star, a cepheid. Its distance, mass and age should be easy to measure. But new calculations keep disagreeing with one another and failing to make sense.
A new theory suggests that dark matter might not be made of undiscovered, never-before-seen particles. Instead, researchers write, it might be made from a type of "hexaquark" detected in 2014.
