We may soon be able to read long-lost ancient scrolls damaged by the eruption of Mount Vesuvius

X-ray technology and artificial intelligence—along with the discovery of lead in the ink of fragments from a collection of ancient Roman scrolls—could soon help scientists read long-lost texts buried by the eruption of Mount Vesuvius in 79 CE, according to a study published Sept. 16, 2026, in the journal PLOS One by Douglas Seiler, an affiliate of the University of California, Berkeley, U.S.; Jacob Michael LaManna of the National Institute of Standards and Technology, U.S.; David Kreimer of the University of California, Berkeley, U.S.; and colleagues.

Prime assembly can correct multiple mutations at once, pointing toward universal gene therapies

Genomic editing holds great potential yet continues to have limitations. Current methods either rely on untargeted gene delivery or short DNA edits that need to be individualized for each patient. A new paper published today in Nature describes a novel genome engineering method called prime assembly that allows long DNA fragments to be stitched into precise, programmable target positions within living cells. This approach may allow for the development of universal gene therapies that can be used for many patients.

3D scans reveal how lichen fungi grip algae across cell walls

Lichens colonize trees and rocks all over the world. They are symbiotic communities between fungi and photosynthetically active green algae or cyanobacteria, in which both partners benefit from each other: The fungal partner relies on the algae for a supply of carbohydrates and, in return, it protects the algae from UV radiation and other environmental influences. The contact zone where the fungal cells and algal cells touch is crucial for transferring nutrients between the two symbiotic partners. Detailed investigations, particularly a three-dimensional understanding of this area between the cells, have been lacking until now.

Pufferfish taste receptor more versatile than a human's, detecting both savory L- and sweet D-amino acids

Our sense of taste is critical for survival, alerting us to substances that provide vital nutrients and those that might poison us. Now, a team led by researchers from the University of Osaka has discovered how one such taste receptor in pufferfish can detect a surprisingly wide range of flavors at once. Their study is published in the Proceedings of the National Academy of Sciences.
