In this week's science news, a magnitude 8.8 megaquake hit off the coast of Russia. The enormous earthquake was the joint-sixth largest ever recorded and struck the sparsely populated Far Eastern Kamchatka Peninsula on Wednesday.
Shortly after the earthquake struck, a volcano began erupting on the same peninsula. Klyuchevskoy volcano had shown signs of unrest for weeks, and the earthquake likely intensified the eruption, which sent lava spewing and an ash plume rising to a height of at least 1.5 miles (2.5 kilometers).
The enormous earthquake also led to tsunami warnings across the Pacific, but many of these were subsequently downgraded as the waves weren't as big as initially feared.
Ancient Greek honey
Sticky goo in 2,500-year-old bronze jars finally identified, settling 70-year debate
Researchers have finally identified a sticky goo substance that was found in 2,500-year-old bronze jars from southern Italy. The goo, left over from an offering to an ancient Greek god, has been the subject of archaeological debate for 70 years, but now it's finally settled — the goo is honey.
A team of chemists and archaeologists used cutting-edge chemical analysis to determine that the jars originally contained honeycomb. The ancient Greeks and Romans used honey in medicine, rituals, cosmetics and, of course, food.

THC-laced pizza
Pizzeria mishap left at least 85 people intoxicated with THC after infused oil used for dough
At least 85 people became intoxicated with THC (tetrahydrocannabinol), the psychoactive ingredient in cannabis, after eating at a Wisconsin pizzeria in 2024, a new report revealed.
Famous Yeti's Pizza in Stoughton shared an industrial kitchen with other vendors, including a state-licensed producer of edibles containing delta-9 THC — the most abundant form of THC in cannabis plants. After running out of cooking oil, the pizzeria unwittingly used THC-infused oil from the shared kitchen to prepare dough.
Customers reported experiencing THC exposure symptoms within one to four hours of eating pizza, garlic bread, cheese bread or sandwiches from the pizzeria. The symptoms included dizziness, sleepiness and anxiety.

AI is entering an 'unprecedented regime.' Should we stop it — and can we — before it destroys us?
The artificial intelligence (AI) boom is starting to feel like a runaway freight train, taking us ever closer to the technological singularity — a moment in time when AI develops general intelligence that surpasses human intelligence.
An AI superintelligence is a terrifying prospect in many ways, not least because it has the potential to go rogue and become a threat to us all. However, artificial general intelligence also has the potential to solve some of humanity's other existential problems.
Most scientists predict that artificial general intelligence will exist by 2040, while some think it could arrive as soon as next year. Either way, the birth of superintelligence is seemingly just around the corner.

See the universe's rarest type of black hole slurp up a star in stunning animation
Astronomers have shared a mesmerizing animation of an elusive "missing link" black hole consuming a star at the edge of a distant galaxy. The astronomers believe they spotted this stellar attack in data from the Hubble Space Telescope and NASA's Chandra X-ray Observatory, so they recreated what the event would have looked like in the animation.
The black hole in the animation is a rare intermediate-mass black hole. Astronomers find it tricky to identify medium-size black holes because they don't produce energy jets or bind galaxies together, and they can be misidentified as clusters of smaller "stellar mass" black holes.
