Our society faces the grand challenge of providing sustainable, secure, and affordable means of generating energy while trying to reduce carbon dioxide emissions to net zero around 2050. To date, developments in fusion power, which potentially ticks all these boxes, have been funded almost exclusively by the public sector. However, something is changing. Private equity

The Yellowstone supervolcano in northwest Wyoming isn’t just one of the most fascinating places on Earth, it’s potentially one of the most volatile, thanks to the reservoir of magma contained within. A new study by an international team of researchers has determined that there’s actually more magma under Yellowstone than was previously thought, adding important

A new study has revealed that small lakes on Earth have expanded considerably over the last four decades – a worrying development, considering the amount of greenhouse gases freshwater reservoirs emit. Between 1984 and 2019, global lake surfaces increased in size by more than 46,000 square kilometers (17,761 square miles), researchers say. That’s slightly more

A newly weighed exoplanet has left astronomers deeply puzzled. After taking measurements of a very young Jupiter-sized exoplanet named HD-114082b, scientists have found that its properties don’t neatly match either of the two popular models of gas giant planet formation. Simply put, it’s way too heavy for its age. “Compared to currently accepted models, HD-114082b

Earlier this year, astronomers found an absolute monster of a galaxy. Lurking some 3 billion light-years away, Alcyoneus is a giant radio galaxy reaching 5 megaparsecs into space. That’s 16.3 million light-years long, and it constitutes the largest known structure of galactic origin. The discovery highlights our poor understanding of these colossi, and what drives

Our failure to decisively mitigate climate change is prompting researchers to examine more drastic approaches, like fertilizing the oceans to combat the massive excess of carbon dioxide in our air. “At this point, time is of the essence,” says Michael Hochella, an Earth scientist at the US Department of Energy’s Pacific Northwest National Laboratory. “To

For the first time, scientists have created a quantum computing experiment for studying the dynamics of wormholes – that is, shortcuts through spacetime that could get around relativity’s cosmic speed limits. Wormholes are traditionally the stuff of science fiction, ranging from Jodie Foster’s wild ride in Contact to the time-bending plot twists in Interstellar. But

Archeologists have rediscovered a pre-Hispanic fresco depicting mythological scenes in northern Peru that they had only seen in black and white photographs that were more than a century old. “It’s an exceptional discovery, first of all, because it is rare to unearth wall paintings of such quality in pre-Columbian archeology,” said Sam Ghavami, the Swiss
