Ancient superpredator that lived 328 million years ago was 'the T. rex of its time'
Where did ocean currents come from? | Solar storm from 'canyon-like' hole in the sun could hit Earth as soon as Thursday (Dec. 1) | Fossilized brain of 525 million-year-old deep sea worm likely the oldest ever discovered

A fangy, 6-foot-long (1.8 meters) carnivore that haunted the lakes of what is now the American Midwest would have been a top predator in its freshwater ecosystem — a "T. rex of its time," according to scientists who studied the creature. And it grew up fast, new research finds.
The predator, an early four-legged vertebrate known as a tetrapod, lived around 328 million years ago during the early Carboniferous period.
A "canyon-like" hole in the sun's atmosphere has opened up and may launch a high-speed stream of solar wind into Earth's magnetic field from Thursday (Dec. 1) to Friday (Dec. 2), and will possibly cause a minor geomagnetic storm, according to spaceweather.com.
The coronal hole is a gigantic solar gulf stretching across the sun's center.
AI is changing how Pfizer creates new medications Artificial intelligence is set to play a massive role in how medication is developed going forward. Pfizer is using it to uncover how diseases develop in the body, screen for the best molecules for new medications, and even create individualized treatment plans. Learn more here.
A 525 million-year-old fossilized worm unearthed in China has what is likely the oldest example of a brain ever discovered.
The surprising shape of the brain offers clues about the evolution of arthropods — a group that includes insects, arachnids and crustaceans — and could help solve a mystery that's been puzzling researchers for more than a century.
Wolves infected with behavior-altering parasites are more likely to become pack leaders, or abandon their packs altogether, according to an analysis of more than 200 gray wolves in Yellowstone National Park.
The findings add to a growing body of evidence that Toxoplasma gondii, a single-celled parasite, pulls on the puppet strings of its hosts, goading them into pursuing risky behaviors.
