University of Utah engineering researchers develop a steam-powered fix for ‘sulfur poisoning’ in fuel cells, devices that both generate and store electricity. The team’s rhodium-infused anodes could be a solution to unlock fuel-flexible clean energy.

In Physics of Fluids, researchers from Brown University present two related studies about thin film fluid flows in the kitchen: one about the relationship between how long it takes to tip the remaining liquid out of a container and its viscosity, and the other about the ideal time to wait before dumping water out of a wok to minimize rusting — it’s more effective to wait a few minutes to let the water accumulate so there’s more to pour out.

Luna Labs has selected UNC Greensboro (UNCG) chemistry professor Nicholas Oberlies to lead a NASA-funded project exploring whether fungi can be grown into building materials for construction on the moon and Mars. The project will investigate whether certain fungi can be combined with regolith — loose rock and soil found on the surface of the moon and other planets — to create materials that could one day support construction in places other than Earth.

Dogs come in all shapes and sizes: from giant fluffy Newfoundlands to tiny short-haired Chihuahuas. And many furry companions like to spend their days inside near their humans. An initial study published in ACS’ Environmental Science & Technology reports that dogs — both big and small — impact indoor air quality. The researchers found that small active dogs produced more airborne particles, but larger animals released more microbes into the air than people did.
