Never seen the death of a ciliate like this-- usually it's too much pressure from the coverslip or too much osmotic pressure. But this gradual posterior-to-anterior "unzipping" effect amazed me ! Motic BA310e - 40x Objective - sped up 2X #microscopy #Paramecium #Iteachbiology #edusky

Had a blast last week at the @nabtbio.bsky.social national conference & got to present to several dozen Bio teachers about the #Microsafaris you have seen here over time. Even did a live demo & captured this elegant Stentor showing off for those awesome teachers! #iteachbiology #microscopy #Edusky

Ep. 6 of Safeguarding Sound Science is out! This week, Mat Kaplan sits down with Todd Disotell (@todddisotell.bsky.social) for an enlightening, and sometimes sobering discussion about how we may fare in the event of another pandemic. #podsky #sciencesky #virus #evobio

@evoexplorer.bsky.social absolutely crushing his presentation on microsafari. @nabtbio.bsky.social A privilege to call this talented man my friend.

Excited to head to St. Louis & the @nabtbio.bsky.social Conference tomorrow & get to see many old friends and make new ones! Also excited to present (for the first time!) my MICROSAFARI project on Saturday at 9:00. I hope to see some of you there! #NABT #NABT2025 #NABTStLouis #iteachbiology #edsky

yall my dad wrote this!! a middle grade book about human evolution ⚡️⚡️⚡️ pre-order a copy for your kiddos! @evoexplorer.bsky.social

AUTISM and TYLENOL A study of 2.5 million children showed a small association between acetaminophen use during pregnancy and autism—but this finding DISAPPEARED when full siblings were compared. “Acetaminophen use during pregnancy was not associated with children’s risk of autism…” Full article:

From a desktop "mini pond" I maintain just for kicks --- Love the internal detail of the Aeolosoma as it wanders around. Also notice some blue microplastic and a stentor. Motic BA310e 10X objective via LabCam Ultra & iPhone 15 #microscope #microscopy #nature #biology #edusky #Iteachbiology

I am a true fan of Stentor and was able to capture this cooperative one with my 60X objective. I just love seeing the myonemes, the moniliform nuclei, and the cilia active as it "grazes." Motic BA310e - 60 X objective - Labcam Ultra -iPhone15 #iteachbiology #microscope #edusky #science #nature

Happy #MicroscopeMonday! This video from an aging pond sample showcases Paramecium, some cysts of hypotrich ciliates (likely Oxytricha), and a mat of Zooglea bacteria at the end..... Motic BA310e 20X Objective/ LabcamUltra/iPhone15 #iteachbiology #microscope #edusky #science #nature

Just fiddling with an aging sample from my desktop "mini-pond" I love the worm Aeolosoma in darkfield because you can appreciate its internal structure so clearly. Motic BA310e/ 10X objective/Labcam Ultra/iPhone 15 #microscope #nature #biology #edusky #science 🧪

Microverse Minute I collected samples from a local fountain several days after a good rain, and the sediment was loaded with these micro crustaceans called Ostracods!! They date back in the fossil record over 400 million years! #microscopy #naturephotography📷 #science #biology

Always love getting to see a microscopic population explosion in my samples! Here's a Paramecium undergoing binary fission to create two clones! Motic Ba310e / Lbacam Ultra/iPhone 15/ 10X objective #nature #microscope #biology #iteachbiology #edusky #science #naturephotography

It's fun to let students in their free time create "Mix slides" from different pond samples & then see what appears.... this "mix" has at least 4 species. Aeolosoma, Paramecium, Rotifers, and Stentor Can you spot any species I missed? #microscope #naturephotography #biology #iteachbiology #edusky

Yesterday I collected some samples from a local Texas pond and was happy to see a bunch of Nauptili. I thought y'all might appreciate this video of one of them -- apologies for a messy condenser --- that gets cleaned this weekend! #microscope #Iteachbiology #edusky #nature #microscopy #Science

Just saw this recently deceased copepod with a hefty load of peritrich epibionts (I think Vorticella). Excited to see the egg sac with eggs that already have eyes developing. It's my first time observing this! #microscope #edusky #nature #biology #iteachbiology #science

From a local park pond, a nice cluster of Vorticella - I am always puzzled by how they manage to feed when it seems they are constantly retracting in response to stimuli. Motic BA 310e - 4X objective - LabCam Ultra & iPhone 15 pro #edusky #microscopy #Biology #nature #microcosmos

It's always nice when you see a nauplius that isn't hell-bent on zooming everywhere. LOL *For my non-bio friends, a nauplius is a larval form of a crustacean. I suspect this one belongs to the genus Cyclops - a copepod. #microscopy #nature #biology #edusky #iteachbiology #science

From a Texas pond - I love seeing Urocentrum turbo doing its thing here. Amazed they have enough energy to keep on spinning without obviously feeding like other species of ciliates. ENJOY! Motic BA310e - 4X Objective with Labcam Ultra / iPhone Pro 15 #microscope #iteachbiology #edusky #biology

I am working to develop thought exercises for my students that cannot be solved by a simple Google or Chat GPT query. I'll show them this short video & challenge them to figure out what I have filmed here. Do any of you know what I have filmed? #iteachbiology #educhat #ai #scied #edsky

Microverse Minute No 9 TARDIGRADES - WaterBears - Moss Piglets! One of the last samples my students get to see is the most anticipated - WaterBears, which you see here in darkfield -- notice the shed cuticle of one with eggs laid inside! #iteachbiology #microscope #edusky #science #nature

Lovely day yesterday exploring Vancouver - great scenery,culture, and thoughtful wildlife rehabilitation organizations. #wildlife #Canada #Nature

A FANTASTIC day of Glacier viewing yesterday!!! Early morning cruise up the Endicott Arm and a beautiful, moody view of the Dawes Glacier... later on outside of Juneau, we had a nice peek at the Mendenhall Glacier.

Thrilled to announce that my FIRST book "Reading The Bones - Homo naledi & the Mysteries of Human Evolution" (Co Authored with Marc Aronson) is now available for preorder! A dream come true! us.macmillan.com/books/978037... Thanks to @fsgbooks.bsky.social & @mackidsbooks.bsky.social

Parents, be vigilant against PragerU instructional materials in your kids classrooms! It’s an extremist outfit masquerading as an educational nonprofit. It’s a far right wing response to PBS kid’s programming, it is propaganda designed to appeal to children and careless or bigoted educators. Beware!
