What Can Singing Frogs Teach Us About Evolutionary Tradeoffs? — Galactic Polymath
Will female frogs be attracted to males who produce many short calls or to males with fewer, longer calls? This evolutionary tradeoff was the question my high school biology students investigated in t...

"Pat, why do you carry that ridiculous 600mm lens on long hikes?"

Buddy, I can see mountains reflected in the eyes of a trailside pika.

They ended the experiment when either copulation or cannibalism occurred with the pair! 😂

An inspiring workshop in Long Beach on ocean plastics hosted by Algalita Marine Research and Education. Highlights were collecting beach nurdles, seeing urban sea 🐢, & a homegrown dinner @ Captain Charles Moore's house, who raised the alarm on the Great Pacific Garbage Patch.

Looking to bring real-world stories into your classroom?

I’ve been using free films + classroom guides from @scicommlab.bsky.social‬, and they have changed how I teach science.

Spent a week in Oregon w/ Project ICE & COLDEX-Center for Oldest Ice Exploration. From holding 5,000 year old ice & seeing the gases trapped is inside, to sampling a 60,000 year old ice core (& keeping it afterward!), to seeing foraminifera fossils as climate indicators…it was an amazing week! ❤️🧊

They’re popular, they’re polarizing, and at this point, we’ve all heard about them: GLP-1 medications like Ozempic. Here’s how they actually work, from the former FDA commissioner who’s taken them.
How Do GLP-1 Drugs Override Our Biology?
In his new book, a former FDA commissioner unpacks the latest science on metabolism, weight loss, and how GLP-1 drugs actually work.

Did you know that sea slugs steal chloroplasts from algae as portable snacks?! Neither did I, but a new Cell paper demonstrates that they do. 🐌🧪

My favorite part is the researchers called the storage for these stolen hors d’oeuvres “kleptosomes” 😂🥰

Summary from Nature & Cell paper linked below.
‘Wildest thing’: solar-powered slug steals chloroplasts and stores them for emergencies
Marine creatures house contraband structures in special organelles, which the animal raids for food in times of need.

If, like me, you wore glasses in school, you're gonna have some empathy for our #FishOfTheWeek. In the photo below, the four-eyed fish doesn't look very strange at all. But trust me, these guys are far stranger than they seem at first glance

RFK Jr.‘s extreme anti-vax views — and his related conflicts of interest — were a huge problem during his confirmation process.

So he promised not to change the vaccine advisory panel.

Today, he fired every single expert on that panel. It's a public health disaster.
RFK Jr. ousts entire CDC vaccine advisory committee
Health Secretary Robert F. Kennedy Jr. has removed every member of a scientific committee that advises the Centers for Disease Control and Prevention on how to use vaccines.

One of the most thoughtful end of the year gifts from a student that used to live in Hawaii and he made it himself, so talented! Happy Summer everyone! 🥰 😎🌺

Students examined plastics in our environment by sampling the air for microfibers (there were lots!), viewing H2O samples from the Great Pacific Garbage Patch, sifting through ocean beach sand (many nurdles & microplastics). Looking forward to learning more of the impacts this summer with Algalita!

Believe it or not, all three of these fish are the same species… the bluehead wrasse. Wrasses are protogynous hermaphrodites, meaning they transition from female to male over the course of their lives. Each phase can look radically different from each other as evidenced here #coralcitycamera

Using remote sensing, students tracked bats in the woodlot behind our school and learned about WNS (white-nose syndrome), a fungus spreading among native 🦇 populations, interrupting their hibernation and killing bats in Michigan and other states. #place-basedteaching

AP Bio learned about parental care to discover mom & dad pigeons make milk by performing a mock brain biopsy & ELISA test for the presence of prolactin. Then modeled prolactin gene activation & learned of other lactating non-mammals. The 3rd case study I authored for Science Communication Lab! 🙂

Look forward to this day every year where my students get to learn suturing from a real cardiac surgery PA. Thanks Dr. Jose Valdez, Dr. Thomas Meitzler, and Annie Meitzler, RN for teaching my AP Biology classes this skill!

AP Bio students determined why okapi at the local zoo are not breeding by analyzing their urine cortisol levels, examining their zoo enclosure, modeling the HPA-axis, & redesigned their zoo enclosure to reduce their stress & encourage breeding. Based on @BeccaCalisi research & a @scicommlab film.

Fun day having students listen and view 🐸 call spectrograms then calculate the call durations and frequencies to determine who will attract the most frog ladies! Students learned about tradeoffs, either long calls or frequent calls, you can’t have both! Great lessons by @galacticpolymath.com

Students listened to 🐸 calls and analyzed their spectrograms to learn about tradeoffs in nature: frogs can have long calls or frequent calls, not both! Then tried to figure out which call attracts more ladies.

Great lesson set called Balancing Act by Galactic Polymath! www.galacticpolymath.com
