How smart was the T. rex? A 2023 study proposed that dinosaurs like it had over 3 billion neurons, more than a baboon, suggesting the T. rex was more intelligent than presumed. But new research found that it was probably more like a crocodile. Popular Science elaborates on the continued paleontological debate. https://flip.it/MdRZHW

The so-called “great instability” event that sent gas giants careening through space until they settled into orbits occurred between 60 and 100 million years after the birth of the solar system. Migrating planets primarily Jupiter, it turns out, may have led to the formation of Earth’s moon. Live Science explains: https://flip.it/wWBTEy

A forest in Utah made of a single tree known as Pando has 47,000 stems and has amassed 6,000 metric tons of life in its thousands of years on Earth. It’s the largest living organism on the planet in terms of mass. Naturally, something that large and old has something to say, and recordings released this year let us “hear” it like never before.

The record-breaking rain that recently fell over the United Arab Emirates and Dubai was driven partly by climate change, a team of 21 scientists and researchers found. The extreme weather was 10-40% more intense than what locals would normally see in a typical El Niño year and resulted in around two dozen deaths. CNN tells us more: https://flip.it/gTpejq

Turns out the moon is not made of cheese, though it would have been a popular appetizer at your next dinner party. A thorough investigation revealed that Earth’s satellite has an inner core with a density similar to iron, which appears to settle the longstanding debate over it being solid or molten. There’s more in this Science Alert article, including how astronomers made the discovery and why it could lead to a better understanding of the solar system. https://flip.it/0nP7A1

The first glow-in-the-dark animals may have been ancient corals deep in the ocean.

AP quotes a new study's author: "Light signaling is one of the earliest forms of communication that we know of — it’s very important in deep waters.”

The idea that matter is mostly empty space is mostly wrong.

From Big Think: "Practically all of the matter we see and interact with is made of atoms, which are mostly empty space. Then why is reality so... solid?"

Is life capable of spreading from planet to planet? A pair of astronomers recently proposed a detection strategy based on the concept of panspermia, the idea that life can start on one planet and spread to others by hitching rides on meteorites. More from Live Science: https://flip.it/ef13Z0
