True nightmare fuel: Scientists just confirmed the first known death from a severe meat allergy caused by a tick bite. The man, who died in 2024 after eating a burger, had alpha-gal syndrome, a bizarre disease triggered by tick bites. www.scientificamerican.com/article/man-...

Clinicians are noticing a steady climb in diagnoses of ARFID, a type of eating disorder that presents as a food avoidance so persistent and pervasive it can cause severe malnutrition in kids and adults. More @sciam.bsky.social: www.scientificamerican.com/article/what...

Now on @sciam.bsky.social: Did astronomers photograph UFOs orbiting Earth in the 1950s, years before human activity there? New peer-reviewed studies suggest the answer is “yes,” but skeptics say these conclusions are premature. By @astrojonny.bsky.social. www.scientificamerican.com/article/did-...

These were the dinosaurs that faced the asteroid. Some of the last survivors. They lived in New Mexico, 66 million years ago. Among them was Alamosaurus, the size of a jetplane. We unveiled them, and their true age, today in a new paper in @science.org !

Please enjoy this female Golden-crowned Kinglet eating a hover fly(?). I saw her in Cape May, New Jersey, the other day. Kinglets are usually pretty frenetic. This one was so focused on holding onto her meal that she slowed down enough for a photo. Look at her cute orange feet! 🪶 Image: Kate Wong

When did big multicellular organisms evolve — and how many times did it happen? In my first big print feature for @sciam.bsky.social, I wrote about *extremely* controversial 2.1 billion year old specimens from the Francevillain, and the question of how to recognize life on a basically alien planet

Proud to share a new piece in Scientific American co-authored with the brilliant @lnwilson.bsky.social , edited by @katewong.bsky.social, and featuring this spectacular depiction of the endless daylight of the Cretaceous summer in Alaska by Chase Stone! www.scientificamerican.com/article/how-...

Six of the nine Nobel Prize winners this year work in the U.S. Three of the six were born outside the U.S., which is the pattern most years. No country has benefited more from welcoming immigrants from around the world. www.nobelprize.org

Wow—thank you @rebeccarhelm.bsky.social for investigating this video. When I saw it a few weeks ago I wondered whether it was legit. It’s absolutely incredible!

I love this whole wonderfully evocative thread about Ötzi the Iceman and his final journey so much 😍😭🧪

Chimpanzees get a surprising amount of alcohol from the fruit they eat. This discovery might bolster the "drunken monkey hypothesis" for humanity's love of liquor 🧪🍸

New dome-headed dino just dropped. 🧪 (Very fun story by @jack-tamisiea.bsky.social)

Right now, millions of birds are migrating south before the onset of the boreal winter. @ksepkalab.bsky.social and I explore the evolutionary origins of this amazing behavior in our article for @sciam.bsky.social! www.scientificamerican.com/article/how-...

I loved talking with Marty Martin and Art Woods about how our understanding of human origins has evolved since 1845 for their excellent podcast, Big Biology 🧪

The LIGO project is one of the coolest things going, and the Trump admin wants to effectively cancel it. Here's hoping it can keep on making amazing discoveries like this one 🧪

You absolutely need to know about this fish that has Forehead Sex Teeth 🧪

Look, who are you to judge the spotted ratfish and it's personal kinks. It likes things a little spicy. So what?

Behold the gloriously weird Spotted Ratfish. It has teeth on its forehead for sex. The teeth line a cartilaginous appendage called a tenaculum that in males can be erected and used to grasp a female during mating 🧪

I wrote about how Hurricane Katrina helped spur pretty remarkable improvements in hurricane forecasts since 20 years ago and how current and planned budget cuts by the Trump administration to research could set us back.

It's Scientific American's 180th birthday! To celebrate we have stories on 180-degree turns in science--times when scientists did an about-face in light of new evidence. My essay looks at how the notion of human uniqueness has evolved. Turns out a lot of other species share our "special" abilities 🧪

Feast your eyes on this spectacularly spiky ankylosaur 😍 🧪

I have a real shitshow of a science story here for all my friends: 🧪 www.scientificamerican.com/article/thes...

Fossil teeth reveal a new species of human ancestor, one that co-existed with the earliest known members of our own genus. I love thinking about how, although Homo sapiens is the only human species around today, for most of human prehistory, multiple human species roamed the earth 🤯 🧪

A blue bee! This is the blue carpenter bee, Xylocopa tumida. I was SO excited to find this animal just before dawn at Trus Madi Entomology Camp in Borneo. So full of beauty.

🧪 I've been interested in female agency in ape dispersal for a long time, v cool to see new work in gorillas. It's fascinating to imagine their, and young female chimpanzee, experience in making these choices - going off alone into forest, encountering other groups, trying to find friends

Stone tools from Sulawesi at least a million years old may be even more ancient than those found on Flores, suggesting an even earlier presence of hominins on Wallacea www.nature.com/articles/s41...

New world record longest lightning strike just dropped! 🧪 (by @dodecalemma.bsky.social for @sciam.bsky.social)

My brother did not ask me to do this, nor did he know I was going to, but I made him a mashed potato volcano for his birthday. The number of potatoes this required was shocking but otherwise it was relatively simple to do. A side effect is a freezer full of leftover mashed potatoes.

New story by my colleague @mfischetti.bsky.social showing where the magnitude-8.8 Russia earthquake ranks among the strongest ever recorded. 🧪

Now on @sciam.bsky.social, by @nadiadrake.bsky.social: The U.S. has axed CMB-S4, its boldest cosmology experiment in generations. Tight budgets and crumbling infrastructure helped doom the project, which was meant to test cosmic inflation. RIP. www.scientificamerican.com/article/u-s-...

For 40 years, virus detectives have flocked to NJ beaches to track avian influenza. Their clues? Bird poop 💩 I followed that team to explain H5N1's history in a special Science Quickly podcast series. Featured today in @sciam.bsky.social's bird flu issue: www.scientificamerican.com/podcast/epis...

We finally made it to Bluesky—just a few billion years after the Big Bang, and only slightly late to the party ✨🌌 We’re sharing some of our best stories from the year so far to kick off our Bluesky journey!

In this month's issue of Nature Ecology & Evolution, we celebrate 200 years since the birth of Henry Walter Bates, who gave the first scientific account of mimicry in butterflies [thread] 🦋 Editorial: Bates’ many contributions www.nature.com/articles/s41...

100 years after the Scopes trial, in which John Scopes was found guilty of breaking a law against teaching human evolution in school, U.S. education is still under attack from the same religiously motivated political forces that led to the Scopes verdict 🧪 www.scientificamerican.com/article/amer...

And here is a whole host of expert comment on the Moa/Colossal announcement -- well worth a read, with lots to think about. www.sciencemediacentre.co.nz/2025/07/09/m...

Our excellent graphics editor @jenchristiansen.com gives a great History of Scientific American talk to each new class of interns here. Today we all learned that SciAm is older than STAMPS (in the U.S. at least). Also, please look at this screenshot of our early AOL page.

We'll be talkin' birds in a couple hours!

Fun! @evoswami.bsky.social is quoted from the interview on @sciam.bsky.social by @katewong.bsky.social on "Wait, Wait Don't Tell Me" from @npr.org! (min 34:50) www.npr.org/2025/05/24/1...

Technology has made it easier than ever to find and identify birds, but something wonderful happens when you put your phone away and just *watch* these incredible animals. Maine birder Derek Lovitch makes the case for slow, analog bird-watching 🪶🧪

THE WARBLERS ARE COMING!!! Found these guys this morning in Connecticut in a big mixed flock of migrants. Black-throated Green Warbler, Black-and-white Warbler, Palm Warbler and a very dull Pine Warbler. Hooray for spring migration! 🪶
