Earth's largest land animals are limited by salt.

Sodium availability constrains the density and distribution of elephants, giraffes and rhinos across Africa, and offers a new explanation for the so-called 'missing megaherbivores'.

Very excited to see Yellow-bellied Sapsucker holes on this tree during season 5, episode 1 of Stranger Things. Will this tree’s counterpart in the Upside Down still have sapsucker holes? πŸ€”

If birds were actually government drones, then there wouldn't have been any birds during the shutdown.

7 basic science discoveries that changed the world Ozempic, MRI machines and flat screen televisions all emerged out of fundamental research decades earlier β€” the very types of study being slashed by the US government.

Scientists point to a long list of findings that emerged out of fundamental research, the type of studies the US government is cutting, and went on to change the world. Nature lists a few of their examples. πŸ§ͺ

A meme with two panels. The top panel shows trees at night completely wrapped in bright white Christmas lights, making the area glow intensely. The bottom panel shows a man in bed with his eyes half-closed and red, looking pained and exhausted as if unable to sleep. The caption across the bottom image says, β€œThe bird trying to sleep in its nest be like.” The meme humorously suggests how birds might feel if their tree is covered in blinding holiday lights.

It’s that time of year when this meme becomes relevant again… 🫣

One of the amazing things about science is we will never run out of mysteries.

Take "Naturwissenschaften (2003) 90:495–500", which performed a survey of 10,000 dinosaur fossils for evidence of tumors in the bone.

I was prepared for yes, no, but what I wasn't prepared for was:
"only in hadrosaurs."

Confused writing is usually a symptom of confused thinking. As we struggle to clarify writing, we clarify our thoughts. AI writing aids rob us of that struggle, leaving clean-looking text and thoughts still confused for lack of inspection. Writing is not just a product; it is a diagnostic tool.

This desert beetle runs to cool off After a sprint, the temperature of the beetle Onymacris plana drops. Efficient running, a body built for cooling and a little bit of lift all help.

This paper was published 40 years after the original fieldwork was conducted. It’s never too late to share cool research!

Hey is it bad if google AI search results stop people from leaving google dot com 99% of the time? All our news and information creators can survive just fine with one percent of their previous search traffic right? I’m sure it’s fine. www.404media.co/googles-ai-i...

Did you know that since 1750, land-use change is responsible for about *one-third* of total CO2 emissions released to the atmosphere?

About 255 billion tons of carbon, or nearly *a trillion tons of CO2e*, have been emitted.

That's basically the ghosts of *2 billion hectares of forests* in the sky.

Read news, op-eds, and analysis, not AI summaries. Create your own art (even if it's messy) or hire an artist to do it. Do your own homework. Talk to people, not chatbots. Keep your thinking and skills sharp and cherish our messy humanity. That's the new punk rock.
