Eye Again
“Eye for an eye” may not cause snail blindness. Researchers learned how apple snails fully regenerate lost eyes.
Full regeneration: 28 days from amputation
No stem cell dependency
Relies solely on retinal and optic nerve tissue systems
Full regeneration occurs in juveniles and adults with no lingering effects after multiple eye replacements. Further research could offer insight into neural and tissue regeneration treatments in humans. No slimy side effects, please.

Digital Pollen
Brace your seasonal allergies, the Smithsonian just digitized over 18,000 pollen samples in PollenGEO.
PollenGEO: free online pollen database
Samples span 200 years of collection
Enables high-res image search for specific traits
PollenGEO is being used to train machine-learning models that will shortcut hundreds of hours in identifying new pollen grains. The fully digitized database will also aid in tracking climate change impact. And my seasonal shifts in breathing efficiency.
This reminded me of one of my favorite pollen-related stories, the heist! 👇
Pollen Heist
Some bees chomp down to get more pollen. Researchers observed bumble bees violently shaking after selectively biting buzz-pollinated flowers.
~9% of plants are buzz-pollinated
Buzz-pollinated = pollen is concealed unless shaken loose
Biting + shaking releases more pollen than just shaking
Not all buzz-eligible landings were shaken, though researchers aren’t sure how bees decide. Future studies will help us better understand this behavior to track environmental impacts on pollination. Fine, I’ll stop biting the flowers.

Last week: “Which nursery rhyme is better?”

Steve made this in Procreate
According to itsy bitsy spider lore, the smol arachnid needs the little star to twinkle twinkle and dry up all the rain. Lest it resort to a life absent crawling up spouts again.

Steve made this in Procreate
Apple snails inspired st3v to try regrowing his own eye. It regenerated almost immediately, he just asked me to draw it smaller for “dramatic affect”.

Myth: Pet insurance isn’t worth the money
Did you know that one pet health emergency can cost up to $10,000? That could put a huge strain on your savings or even force you to max out your credit cards. Protect your budget and your pet by thinking ahead and choosing a plan that works for both of you.
