"...the sea worms simultaneously cleave their bodies in two. Their anterior parts continue life as usual on the reef, but the posterior ends undergo a transformation—growing rudimentary eyes and preparing to procreate..."

Allow me to introduce you to the palolo worm. This marine critter is known for its spectacular spawning events that happen on one single night every year, making a lasting mark on many Indigenous cultures in the southwestern Pacific. For @biographic.bsky.social: www.biographic.com/the-moon-of-...
Across the southwestern Pacific, sea worms spawn in concert at the same time each year--anchoring ecological calendars and even shaping communities' sense of time.

Thanks so much for the kind words, Krista - I absolutely love how this story turned out! 🪱
It's always a delight to work with @katarinazimmer.bsky.social, and this story checks all the boxes for me as an editor:
✅ Weird invertebrate with fascinating biology
✅ Traditional ecological knowledge that matters in the modern world
✅ Pacific Islands culture
✅ Myths and symbolism
Our distant ancestors self-sufficiently produced their own proteins. Then the started getting them by eating other organisms.
For plant-eaters, meeting their needs is a challenge, but evolution pulled some neat tricks, writes @katarinazimmer.bsky.social :

A blend of chem & molbiol techns are enabling archaeologists to mine ancient sediments for clues about the people who once lived there. New @nature.com, @katarinazimmer.bsky.social reports on the molecular fossils enriching archaeology. www.nature.com/articles/d41... 🧪cc @benmarwick.bsky.social
It was a pleasure speaking with Jorge Cham for iHeartRadio's #ScienceStuff podcast about the perils of AI-generated animal imagery. While this content may seem cute and harmless, I argue they could have real consequences for our relationship with other species: www.iheart.com/podcast/1119...

Great read! Congratulations @katarinazimmer.bsky.social on your insightful @knowablemag.bsky.social piece exploring the remarkable biology of the Aedes aegypti #mosquito knowablemagazine.org/content/arti...
Aedes aegypti is the “perfect mosquito”... to spread disease. Dengue, chikungunya, Zika and yellow fever, kill tens of thousands of people in tropical countries every year. And experts worry it could get worse.

Farmers in Gabon notice that elephants sometimes eat the leaves and stems of banana and papaya plants while leaving the nutritious fruit behind. Why?
New evidence shows the elephants may be taking advantage of plants' medicinal properties to treat parasites. Read more:

The most valuable illegally traded wildlife product is not tiger bone. Nor is it rhino horn, or pangolin scales. It's actually rosewood. For @mongabay.com I looked into new technologies - from AI to DNA metabarcoding - that could help end the rosewood heist:

“It’s really easy to make a wolf, because wolves eat basically what their body looks like. Their diet mirrors their body. But it’s really, really hard to make a moose, because a moose’s diet does not.” How do plant-eaters get their protein fix? @katarinazimmer.bsky.social @knowablemag.bksy.social👇🧪
Early animals took an evolutionary risk: They gave up the ability to synthesize 9 of the 20 amino acids that living things need to make protein. Scientists are now learning how they ensure they get these amino acids from their diet.

AI-Generated Animals Are Distancing Us From Nature

“I think that’s probably one of the biggest issues—that it gives the impression that actually the environmental messages are less serious than they actually are”, Gosler.
AI-generated imagery of animals may seem harmless, but experts worry that it could worsen the public's understanding of wildlife, harm conservation, and even erode people’s general interest in nature.

Lots of animals eat poisonous plants and critters and survive. How do they do it? I looked into this mystery in my latest for @knowablemag.bsky.social:

For many species threatened by sea level rise, translocation may be the only way to save them. Learn how conservationists are moving rare tree cacti and threatened seabirds to higher ground and helping entire marshes shift inland, in my latest for @nwf-south.bsky.social:

A rare piece of good news: New research reveals how the Ampurta - a small carnivorous Australian marsupial - is thriving despite drought conditions. My story for @nautil.us showcases its nifty drought-resisting tricks that made this feat possible

Around the world, growing quantities of drugs are excreted by human bodies and slip, along with wastewater, into lakes and rivers. My latest for @cenmag.bsky.social explores how this is influencing the behavior, reproduction and biology of aquatic animals

There’s more to seed banks—efforts to preserve threatened plants—than simply storing the seeds safely, @katarinazimmer.bsky.social explains:
