‘Disgust' among first words decoded in 2,000-year-old charred scroll
Scholars are decoding an ancient scroll that was one of hundreds charred to a crisp during the eruption of Mount Vesuvius in AD 79.
The artifact, which is kept at the University of Oxford's Bodleian Libraries in the United Kingdom, is the fifth intact Herculaneum scroll to be virtually unrolled as part of the Vesuvius Challenge, a competition designed to accelerate the deciphering of the scrolls that form an unprecedented cache of information about ancient Rome and Greece.
Using artificial intelligence and other computer-based techniques to piece together the scroll and enhance the ink, the Vesuvius Challenge team has successfully generated the first images of text inside the scroll, known as PHerc. 172. The library group said Wednesday that it has begun to interpret the columns of text.
One of the first words to be translated was the ancient Greek διατροπή, meaning 'disgust,' which appears twice within a few columns of text, the Bodleian Libraries said.
'It's an incredible moment in history as librarians, computer scientists and scholars of the classical period are collaborating to see the unseen,' said Richard Ovenden, Bodley's librarian and Helen Hamlyn Director of the University Libraries, in a statement.
'The astonishing strides forward made with imaging and AI are enabling us to look inside scrolls that have not been read for almost 2,000 years.'
Deciphering ancient scrolls with AI
The scrolls would crumble if a researcher were to attempt to unfurl them by hand, likely destroying any trace of script.
Brent Seales, a professor of computer science at the University of Kentucky and cofounder of the Vesuvius Challenge, said the Oxford scroll, of all the Herculaneum scrolls scanned to date, contained the most recoverable text, with the chemical composition of the ink appearing more clearly in X-ray scans.
Researchers think the ink may contain a denser ingredient, such as lead, but further testing will be needed to identify the precise recipe that has made the ink so much more legible than other scrolls that have been part of the Vesuvius Challenge, the Bodleian Libraries said.
'Despite these exciting results, much work remains to improve our software methods so that we can read the entirety of this and the other Herculaneum scrolls,' Seales said in a statement.
Seales told CNN last year that the key challenge has been to virtually flatten the documents and distinguish the black ink from the carbonized papyri to make the Greek and Latin script readable.
The machine-learning techniques are not decoding the text but amplifying the readability of the ink used to write the scripts, he said. Transcription and translation of the text will rely on human scholars, including those from the University of Oxford, the library system said.
Researchers are further refining the images of the scroll in hopes it will improve the clarity of the lines of text visible and perhaps reach the innermost part of the carbonized scroll, where the title of the work may be preserved.

Five-armed creature — covered in ‘axes' — found off Taiwan. See the new species
In the rocky intertidal zones along the coast of Taiwan, a five-armed creature scuttles along the seafloor. Its brown, green and black body blends in with the colorful rocks as it glides across the bottom. The animal is a brittle star — and a new species. Brittle stars, or ophiurida, may look like classic starfish, but their long and flexible arms set them apart from their more rigid cousins. They can move quickly thanks to muscles that move a series of vertebrae-like structures linked together with ball-and-socket joints, according to the University of California at Berkeley. The new brittle star was collected off the southern coast of Taiwan and around a few barrier islands, according to a study published June 6 in the peer-reviewed European Journal of Taxonomy. The animal's central structure, or dorsal disc, is 'covered with fine granules,' according to the study, while the arms are covered in spines. The long arms are made up of spiny plates that fit together like puzzle pieces, photos show. The pattern on the arms also gives the new species its name, researchers said. Breviturma securis, or the axe brittle star, derives its name from the Latin word 'securis' meaning axe, 'referencing the axe-shaped dark patterns on the dorsal arm plates,' according to the study. The body as a whole is 'yellowish-gray to greenish-gray' with 'lighter and darker patches,' researchers said. 'These regions are adorned with discontinuous short dark lines that never form a reticular pattern,' according to the study. 'In juveniles, a dark 'star' may occasionally appear at the center of the disc but never connects to the arm base.' The brittle stars live in the sandy material below rocks from intertidal zones to shallow waters around 25 feet deep, researchers said. They are also commonly found in the same areas as other related brittle star species. Breviturma securis was previously misidentified as another species and appeared in a series of field guides and photographs under the wrong name, according to the study. The new research, with DNA confirmation, will allow these resources to be updated, researchers said. The holotype, or primary specimen used to describe the new species, was found in Taitung County on Taiwan's southeastern coast. The research team includes Kai Chang and Hsi-Te Shih.

How do clouds get their shapes?
Take a look at the sky on any given day and you'll likely see clouds of different shapes — some look like cotton balls, others are fine and feathery or tall and imposing. But what gives a cloud its distinct appearance? The answer lies in a mix of factors. To understand how clouds get their shape, it helps to understand the basics of how they form. When air rises and cools, the water vapor it holds condenses into tiny water droplets or ice crystals. If enough of these particles cluster together, a visible cloud forms. Scientists typically classify clouds into ten main types, based on their shape and how high they appear in the sky. For instance, cumulus clouds (from the Latin for 'heap') resemble a pile of cotton balls, while stratus clouds (meaning 'layer') stretch out like blankets and cirrus clouds (Latin for 'hair') look feather-like. These root names can be combined to describe more complex cloud types—like cirrocumulus. The prefix 'alto' (meaning 'high') helps distinguish mid-level clouds from their lower-level counterparts (such as altostratus vs stratus). The distance of a cloud from the Earth has a big influence on its appearance. Air temperatures decrease with altitude, so clouds that form closer to earth are made mostly of water droplets, while higher clouds tend to be composed of ice crystals. Mid-level clouds often contain a mix of both. This difference in composition influences how clouds look: water-based clouds, like cumulus, have crisp edges and a solid appearance, while icy clouds, such as cirrus, are usually more transparent and diffuse. Air movement also affects cloud shapes. As warm, moist air rises—a process known as convection—it cools and condenses, forming clouds. But something interesting happens in the process: as water vapor condenses, it releases heat, which warms the surrounding air. The warmer air becomes less dense than the surrounding cooler air, making it more buoyant. This increased buoyancy causes the air parcel to rise even faster. 'These upward currents are associated with billows, giving the cumuliform clouds that many of us picture when we think of clouds,' Bjorn Stevens, a climate scientist and managing director of the Max Planck Institute for Meteorology in Hamburg, Germany, told Popular Science. If the air is warm and humid near the Earth's surface but much colder higher up, a fair-weather cumulus cloud can quickly grow into a towering cumulonimbus—the kind that brings thunderstorms. Cirrus clouds, known for their wispy, feathery appearance, are shaped by strong winds high in the atmosphere. These winds act on the ice crystals that make up cirrus clouds, twisting and spreading them into delicate strands. 'The shape also depends very much on the light,' adds Stevens. He explains that clouds are a 'dispersion,' meaning that they're made up of countless particles suspended in air—more like fog than a solid object. 'They don't have a clear end or beginning,' he says. What we perceive as a cloud's edge is actually where sunlight scatters off the droplets or ice crystals within. Sometimes this scattering happens near the cloud's surface, while other times it comes from deeper within the mist, which is why cloud boundaries often seem vague or ever-shifting. The physical features of an area, or the 'topography,' can also influence the shape of clouds. In an article published on The Conversation, Ross Lazear, an instructor in Atmospheric and Environmental Sciences at the University at Albany, State University of New York, explained how air flowing over mountain ranges sets off atmospheric ripples, much like a rock disrupting water in a stream, and leads to the formation of lenticular clouds, which resemble flying saucers. Each cloud is shaped a certain way for a reason. For meteorologists, those shapes aren't just fascinating—they're valuable clues for forecasting what weather is coming next. his story is part of Popular Science's Ask Us Anything series, where we answer your most outlandish, mind-burning questions, from the ordinary to the off-the-wall.
