Lost books by ancient philosophers recovered from 'unreadable' scrolls
Scrolls from the Roman library of Herculaneum that were carbonised by a volcanic eruption have been read in their entirety for the first time, thanks to scans and AI software

The train is ‘my time machine’: a tour of Naples’ hidden ancient wonders
A new film about this corner of southern Italy reveals rarely visited villas, seismic landscapes and a ‘civilisation buried mid-sentence’ – all accessible by trainOne by one, the visitors descend through a tight tunnel cut through volcanic rock into the damp foundations of the Te
Earth's oldest crater really is more than 3 billion years old, new study confirms
In the Pilbara of Western Australia, some of Earth's oldest rocks lie beneath the sky, as they have for billions of years. They are dark, weathered volcanic rocks, close to 3.5 billion years old, cut by veins and stewed by deep time.
Ancient stories inform modern understanding of volcanic eruptions
Ancient stories inform modern understanding of volcanic eruptions
A new international study has found that Indigenous oral traditions, some thousands of years old, hold valuable and often overlooked insights into volcanic eruptions—offering important lessons for modern disaster preparedness. The research, published in the journal Volcanica, was
Fossils upend catastrophist narrative that flowering plants flourished only after dinosaur
A unique cache of plant fossils from volcanic deposits in New Mexico contradicts the common narrative that flowering plants were minor players in Earth's forests until dinosaurs disappeared 66 million years ago.
Traces of Earth's primordial magma ocean discovered in lava from a modern volcanic eruptio
In May 2018, the island of Mayotte, between Madagascar and Mozambique, began to experience a series of earthquakes that led to the discovery of an underwater volcano, now called Fani Maoré. Multiple scientific expeditions followed, taking samples of the recently erupted lava. Whe
Ancient rocks reveal how water reshaped Earth's interior 3.1 billion years ago
Ancient rocks reveal how water reshaped Earth's interior 3.1 billion years ago
Geologists studying some of the planet's oldest volcanic rocks have uncovered new evidence that water was playing a major role in shaping Earth's interior and driving volcanic activity more than 3 billion years ago.
Isotopic signatures link hot spring magmatic water to the subducting Pacific Plate
Water flowing from hot springs near volcanoes often contains a mixture of meteoric water that has percolated underground and a deeper component known as magmatic water. Researchers at the University of Tsukuba used numerical simulations and isotopic data to show that magmatic wat
Volcanoes and wildfires are adding water vapor to the stratosphere, raising climate concer
Moderate volcanic eruptions and extreme wildfires since 2005 have led to an increase in the amount of water vapor in the stratosphere, a layer of Earth's atmosphere above the weather-filled troposphere. That's potentially bad news because water vapor here acts like a greenhouse g
NASA satellites are watching Earth's newest island rise from the sea
NASA satellites are watching Earth's newest island rise from the sea
A newly discovered underwater volcanic eruption north of Papua New Guinea is unfolding in one of the world's most poorly mapped ocean basins. Satellites have spotted steam plumes, ash, thermal hotspots, and huge floating pumice rafts, suggesting magma is rising surprisingly close
In Sicily, drones at work to predict volcanic eruptions
In Sicily, drones at work to predict volcanic eruptions
Hovering over the volcano, a buzzing drone pauses in front of a laser beam on the crater's edge as researchers test whether the devices can measure gases to predict eruptions.
Autonomous drones measure volcanic gas clouds, offering clearer eruption warning signs
Autonomous drones measure volcanic gas clouds, offering clearer eruption warning signs
To better assess the danger posed by volcanoes, researchers at the Technical University of Munich (TUM) have developed a new measurement system. Laser beams are sent through escaping gas clouds and reflected by drones. An algorithm uses the reflected signals to generate a map sho
