Should we be hyped — or freaked out — about nuclear microreactors?

"As of now, 'nuclear energy' in practical contexts refers to fission, or splitting heavy particles to generate massive loads of energy. The goal is to eventually transition to fusion, which combines two light particles, also to produce enormous power but at a lower environmental cost. Each fossil fuel alternative generally has its own share of detractors and ongoing issues, but the debate over nuclear power is among the most prominent, at least from a publicity standpoint. That said, nuclear energy is undoubtedly a robust, high-stakes industry with rapid developments. Governments often get involved, and the balance between innovation and safety is always a significant problem."

Revisiting a 1958 map of space mysteries

"A year after Sputnik launched into space, in 1957, speculation was sizzling.

In 1958, the American Oil Company (AMOCO) released a pictorial map outlining some of the most bedeviling space-related puzzles of the age, and predicting what might happen when space explorers were able to get a closer look. Some of these questions were tied up pretty quickly. … But the rest of the questions on de Reyna's map aren't so neatly resolved."

I tried to prove I'm not AI. My aunt wasn't convinced

"I asked experts if I'm real. Bad news. Even my aunt wasn't sure if I was a deepfake. AI is so convincing that a sitting prime minister struggled to prove he's alive.

'Hell heron': new dinosaur species with a head-mounted sword discovered in Africa

"It's not every day that a new dinosaur is discovered, but it is a great day. Paleontologist Paul Sereno experienced one in Niger when his team unearthed what turned out to be a new species of spinosaurus: Spinosaurus mirabilis. … Sereno's journey started with the writings of a French geologist in the 1950s who mentioned finding a dagger-like tooth in Egypt's Western Desert. No one had ventured so far into the Sahara to follow up, until Sereno's 2019 expedition. There, the team met a local man with a motorbike who agreed to lead them to a spot where he'd glimpsed giant fossilized bones."
