During the Late Pleistocene, ancient cave hyenas (Crocuta spelaea) in the Ural region actively hunted and consumed large herbivores, including bison, giant deer, and woolly rhinoceroses, rather than exclusively scavenging remains left by other predators.

Thank you again for being part of Scientific Frontline.
Mastodon is the only social media we use. The last two months our page views have well exceeded 1 million, most is direct—but word of mouth from you all have played a huge part.
I'll be in for a short time only in the morning. I have a lot of tree trimming that needs attending to. We'll return in the afternoon.
Be well,

We are a species strictly engineered for deep, empathetic connection. Protecting the integrity of that connection—by understanding exactly how it functions, how it is genetically moderated, and how malevolent actors can exploit it—is arguably the most critical scientific and societal endeavor of our time.

Researchers have successfully created quark-gluon plasma, the primordial matter that existed shortly after the Big Bang, by colliding relatively small atomic nuclei (oxygen-16 and neon-20). This extreme state of matter occurs when temperatures and densities are so high that protons and neutrons dissolve, allowing their constituent quarks and gluons to move freely.
