Marcel Proust so famously wrote of the rush of memories invoked by smelling and eating a madeleine cake that the phenomenon of scent-induced nostalgia became known as "Proust's madeleine." Now neuroscientists have figured out how it works in the brain.

Neuroscientists pinpoint how smells bring back childhood memories

Smell can bring back vivid childhood memories—the so-called “Proust’s madeleine” phenomenon—and neuroscientists now think they know why

Thank you to @sciam.bsky.social for letting me dig into the protein enhancement fad. 1. If you are an elite athlete, OR elderly/frail, maybe you do need extra protein. 2. That's not you. You're not an elite athlete. 3. If it is you: consider yogurt. www.scientificamerican.com/article/prot...

Are protein-boosted foods and drinks actually more healthy?

Extra protein can be found in everything now, from potato chips to Pop-Tarts. Does this benefit the average eater?

This is Sadie. She was finally reunited with her human, astronaut Christina Koch, after her mom’s voyage around the moon took her the furthest any human has ever been from their dog. She can't wait to hear all about the universe. 14/10 (IG: astro_christina)

Excited to share this piece by @parshallison.bsky.social and me in the April issue of @sciam.bsky.social. This is my fav type of #dataviz challenge: tackling a concept that is complex, fascinating, and that I haven’t seen represented in this way before. 📊 🧪 www.scientificamerican.com/article/the-...

People often talk about the autism spectrum as if it's a simple sliding scale from "more autistic" to "less." This isn't true — the spectrum is dizzyingly complex, and @unamandita.bsky.social and I set out to visualize this in SciAm's April issue: www.scientificamerican.com/article/the-...

It's been thought since the early 70s that eukaryotes (basically any life with a cell nucleus) wouldn't survive above 62C and no complex life had been shown living above 60C. Until the "fire amoeba"... 🧪 (These are some of my favorite stories to write, just weird neat stuff we're learning.)

This Tiny ‘Fire Amoeba’ Just Redefined Life’s Limits

It was thought that complex cells couldn’t survive above a certain temperature, but a tiny amoeba has proven that assumption wrong
