✨In the DB unit seminar this week, Amrutha Palavalli, a postdoc in the Vu @hanhtkvu.bsky.social group @embl.org, presented a new approach to studying the life history evolution and identifying the trade-offs of the flatworm Schmidtea mediterranea #planarians #sciRNAseq
Why study a flatworm? Because it may hold the key to regenerating human organs. @danimateria.bsky.social from @elpais.com spoke w/ Pres & CSO @planaria1.bsky.social, about what #planarians can teach us about #regeneration, aging, & the possibilities of future medicine.

Top: FISH characterization of the DVB region. Images show the expression of genes along the DV axis relative to the spatial domain of the canonical epidermal marker of the DVB, laminB. Bottom: Transplant animals that received tissue grafted with reversed DV polarity develop goblet-shaped outgrowths. After β-catenin-1 RNAi (10–14d), these outgrowths form head-like structures. Yellow arrowhead, eye.
#Regeneration in #planarians needs new tissue axes to align with existing body axes, coordinated by the dorsal-ventral boundary (DVB). Study shows the DVB is also needed for A-P axis patterning, enabling ectopic head formation independently of the anterior pole @plosbiology.org 🧪 plos.io/4nJX48t

The local land #planarians are not a predator to be under estimated and consistently take down prey far larger than themselves. This #Australoplana sanguinea I filmed finishing off an #earthworm. Quite the brutal battle, I was hoping the earthworm would escape but it was not to be

Planarian Outreach Program: @juliannahaug.bsky.social is teaching students at Blue Valley North about #planarians & their regenerative abilities. With hands-on demonstrations, they’re learning about the #scientificmethod & how to think like real scientists!🔬
Really a good news for future mass screening and #EarlyDetection of soil #Planarians #Flatworms, like #ArthurdendyusTriangulatus, #InvasiveAlienSpecies of Union concern under EU Reg. 1143/2014!
What kind of organism can regenerate its entire body? Planarians! 🪱
In our #UnordinaryOrganisms series, learn why #planarians make unique #research organisms, and how Institute researchers study them to answer questions about organ #regeneration: bit.ly/3ECifsh
🪱 Flatworm #Regeneration: Ultimate Healing! 🔄
#Flatworms, or #planarians, can regrow their entire body from tiny fragments! 🧬
A 1/300th piece can regenerate into a full worm.
Their stem cells, or #neoblasts, allow endless regeneration, making them one of nature’s most resilient creatures! 🌱✨

A shiny black wormlike creature on the brown surface of decayed vegetation. This is a UK non native species of land planarian or flatworm known as Kontikia ventrolineata
We’ve armed ourselves with a natty little OM tough series camera for underwater and some close up work.
First outing amongst some leaf litter was most enjoyable with @wildlifetoursed.bsky.social who certainly has better images of the flatworm #ukwildlife #nature #soil #planarians #springtails.
The red and blue grey colouring of Marionfyfea adventor stands out as it slimes over a moss covered tree stump.
Marionfyfea adventor navigating itself over a purple jelly disc fungus. Its striking colours of red and silvery grey blend in nicely with the pale purple of the fungi.
A globular springtail behind the 15mm long flatworm. This image shows size comparison between worm and springtail.
Winter is a great time for looking little critters.
I’ve shared this Marionfyfea adventor before on here, but these are new images for sm.

I am in desperate need of someone who is working on planarians and/or transfecting GFP in planarian cells? If not, is there a company that provides planarians already with the GFP plasmid. It’s for a HS research project. Thank you all #science #GFP #planarians 🧪🧪🧪
On this Earth civilization evolved from #planarians. These beings are not impervious to pain, but can grow back almost anything due to neoblasts in their system. Whole organs can be damaged & heal, giving them an advantage. The brain is also an organ...& their brains didn't stop growing.

I am not whole.
I am the sum of my parts–the ones I still have, and the ones stolen, alike.

reawakening like #planarians functioning to survive
despite doubletaps to the dome & the endless threat of a restricted identity, they exist within the gated quantum realm of existential strife, with every regeneration, they endure,
but like all finite beings, they can run out of fight. #vss365
The #planarians
were a great group
who wormed their
way to the top
when they were on stage
they certainly could rock
but one night they had a terrible fight
the group was split down the middle
but it didn't matter because planarians
can regroup and so another
super group was formed.

Regeneration might make you crave a little too much chopping! But for us #planarians, that’s simply not okay. Let’s embrace our remarkable ability to heal without all the slicing!
#vss365 #prompt #microfiction
#writingprompt ✍🏼 #writingcommunity
ponder over my coffee
how remarkable
are #planarians
stem cell rejuvenation
what if I was one
my skin would glow
list is too long
wait!
can’t play with nature
aging is unique
freedom of thought
above fear & bigotry
these suit politicians
not planarians
now my coffee is cold!

All the punk rock #planarians have moved on from tattoos and piercings, and are intentionally chopping off their tails to regrow different tails. Flippers and tendrils are popular. Goth #planarians prefer them in jet-black. The lead singer of the Flatworms is credited for starting the trend. #vss365
Oh to be a worm
#planarians defy death itself
just regenerate

Our latest research on planarians funded by @FC3R. Cinnamaldehyde as a pronociceptive molecule and the effects of morphine and Meloxicam. Well done all! #planarians #nociception #FC3R #3R
