Doing a linear stretch on these images shows how dramatic the "edits" were, revealing the deception in clear terms. This should be a complete scandal for Thermo Fisher and more people in the biosciences should be talking about it.
The Thermo Fisher situation keeps getting worse. We've now collected 450+ problematic images presented as verification data in TF's antibody catalog. This includes: 🖌️ Dozens more images with duplications or painting 🖨️ Hundreds of blots that all share the same background (behold slideshow below)
A biotech company that doesn’t know how science and scientific integrity works. Thermo Fisher can be nonchalant because they’re a giant monopoly and people keep buying from them. After this I wouldn’t trust any antibody from them.
Thermo Fisher now has a page up in response to our observations. They flatly deny that images were manipulated or fabricated while repeating that images were "optimized for presentation and clarity on the website", no lie, six times. www.thermofisher.com/us/en/home/l...

TL;DR: We've identified more than 100 cases of apparent manipulation in Thermo Fisher Scientific's antibody verification data. @sholtodavid.bsky.social @johanduchene.bsky.social reeserichardson.blog/2026/05/28/h...
How much of Thermo Fisher’s antibody data has been manipulated?
We’ve documented more than 100 instances of apparent data manipulation in Thermo’s catalog

Surprised to discover that Thermo Fisher appears to show a fake western blot for the validation of one of their p53 antibodies. I've added a diagram to show the very similar bands. This does not appear to be one of the "published figures" but their own internal data.

Electrophysiological development and functional plasticity in dissociated human cerebral organoids across multiple cell lines
Electrophysiological development and functional plasticity in dissociated human cerebral organoids across multiple cell lines
Microelectrode array (MEA) recordings of human neural organoids allow for functional studies of brain network development, but these studies are currently limited in throughput. Pavlinek et al. use organoid dissociation to longitudinally study the development of neural networks and the effects of drug treatment, cell line, and cell-type composition.

Good lesson here. #Organoids and organotypic microtissues are fabulous for particular questions, but probably will always need complementary modelling and human studies. A good modeller knows the limitations and works within those.
“Interrogation of data from cerebral organoids demonstrated that, although broad elements of in vivo development are recapitulated in vitro, many layer-specific transcriptomic programs in neuronal maturation are absent.” Got questions about the brain dynamics, organoids are a dead end. Full stop.

A very well-written perspective on our understanding of Autism for a lay audience 👇
The Trump administration’s autism project “is built on the premise that an autism diagnosis is a terrible tragedy and that scientists and doctors have failed,” writes Roy Grinker. “But science has not failed.”
Sensationalist claims by certain organoid researchers about the degree of similarity or complexity of neural organoids to the in vivo human brain can lead to profound misunderstandings about the capabilities of organoids by researchers and the lay public, this opinion piece being a prime example.

Astrocyte cues boost neuron maturity in forebrain organoids, thanks to protein and nutrient-rich medium. From 2D to 3D cultures, neurons mature faster! PMID:40122897, Nat Commun 2025, @NatureComms https://doi.org/10.1038/s41467-025-58295-3 #Medsky #Pharmsky #RNA #ASHG #ESHG 🧪
Astrocyte-secreted cues promote neural maturation and augment activity in human forebrain organoids | Nature Communications
Brain organoids have been proposed as suitable human brain model candidates for a variety of applications. However, the lack of appropriate maturation limits the transferability of such functional tools. Here, we present a method to facilitate neuronal maturation by integrating astrocyte-secreted factors into hPSC-derived 2D and 3D neural culture systems. We demonstrate that protein- and nutrient-enriched astrocyte-conditioned medium (ACM) accelerates neuronal differentiation with enlarged neuronal layer and the overproduction of deep-layer cortical neurons. We captured the elevated changes in the functional activity of neuronal networks within ACM-treated organoids using comprehensive electrophysiological recordings. Furthermore, astrocyte-secreted cues can induce lipid droplet accumulation in neural cultures, offering protective effects in neural differentiation to withstand cellular stress. Together, these data indicate the potential of astrocyte secretions to promote neural maturat

This looks interesting, but no guarantee the information will be accurate - they say “almost” no hallucinations, I wonder what the error rate is compared to standard chatGPT. Also only trained on Springer Nature papers and protocols so missing out on a lot of information.
