Traditionally, researchers have considered aggregate-scale lime clasts in Roman concretes to be relicts of the concrete fabrication process. Researchers led by Massachusetts Institute of Technology instead argue that these clasts were purposefully included to provide the concretes with self-healing properties.

Implementing new sustainable materials and technologies into designated historical sites is complicated by the need to preserve the area’s historical nature. In Italy, managers of a project to improve the safety of the Archaeological Park of Pompeii worked with the owners of a small family-run business to install solar panels that blend into the ancient city’s traditional buildings.

The Animal Locomotion series by Eadweard Muybridge is a set of glass photographic plates that are widely regarded as the immediate predecessor to the development of motion pictures. Researchers from the Smithsonian Museum Conservation Institute investigated how formation of an amorphous surface layer on the glass plates due to water exposure can impact delamination of the image-containing gelatin layer.

When art historian Meredith Martin was introduced to an 18th-century ballet that allegorically depicts Europe’s pursuit of porcelain, she knew pursuing a historically accurate reconstruction of the ballet would risk reinforcing harmful racial stereotypes and exoticization of Asian cultures. Instead, she and choreographer Phil Chan conceived of a restaging that would center Asian American experience within this history.

With more than 100 million items in the Library of Congress collections, it can be difficult for Library staff to showcase all the wonderful items in storage and educate the public on their importance. Last week, Librarian of Congress Carla Hayden realized the perfect opportunity to highlight one very special item—a glass flute gifted to U.S. president James Madison—through a collaboration with pop megastar and classically trained flutist Lizzo.

More than two years have passed since a massive stockpile of ammonium nitrate exploded at the port of Beirut, killing hundreds and displacing thousands in the capital of Lebanon. The restoration of some shattered ancient glass vessels by a collaborative international partnership serves as a microcosm for the larger restoration efforts.

Mona Passage, a strait which separates the islands of Hispaniola and Puerto Rico, is believed to have served as a reception area for migration groups during the early Common Era. A recent open-access study contends that despite there being a broader regional network of interaction, the stable manufacturing tradition suggests a cultural continuity in the communities that lived there.

As new analysis methods are developed and refined, researchers can illuminate the science behind past techniques that were designed through trial and error. A group led by researchers from the California Institute of Technology used advanced analytical techniques to show how nanoscale engineering gave a historic purple overglaze its distinctive iridescence.
