As city dwellers may know, escaping to the beach can provide a much-needed change of scenery or a mental reset. Historically, some doctors even prescribed trips to the sea to treat diseases. And now, research published in ACS’ Environmental Science & Technology Letters provides another reason to visit the coast. A pilot study found that urban air contained pathogenic strains of Candida yeast that were absent in coastal air samples, revealing a potential transmission method.

Sea foam is a common sight along the coastline as breaking waves churn up air and algae. Now, a study in ACS’ Environmental Science & Technology reports that sea foam from several beaches along North Carolina’s coast contain higher levels of per- and polyfluoroalkyl substances (PFAS) compared to the water below. Some foam samples had more PFAS than what is allowed in drinking water, highlighting the need to clean up and reduce environmental PFAS pollution.

You might think that glass has no business acting as a replacement for bone, but it turns out the two materials have many similarities. Researchers reporting in ACS Nano developed a 3D printable bio-active glass that served as an effective bone replacement material. In rabbits, it sustained bone cell growth better than regular glass and a commercially available bone substitute.
