Figure 1 from a paper published in Nature (linked in post). The figure purports to be an infographic depiction of the "Overall working of the framework" for 'explainably' diagnosing autism spectrum disorder. The infographic is plainly nonsense, containing many spelling errors, nonsense words, meaningless images and graphs. Clearly created using generative AI and (crucially) NEVER CHECKED AT ANY STEP OF THE WRITING OR PUBLICATION PROCESS.

Hey @nature.com, have you got an explanation for how the hell THIS happened? & especially why you accepted a paper with such a bizarre piece of genAI slop in it?!
& more to the point, why we should take you seriously at all going forward?

Credit card fraud
Black neon tetras committed credit card fraud during a 2023 livestream by "Mutekimaru Channel" on YouTube. The owner was using motion-tracking software to turn the fish's movements into Nintendo Switch inputs, letting them "play" video games. 8 In 2020, the fish beat Pokemon Sapphire after 3,195 hours, a feat that takes about 30 hours for a typical human. 9/ 181 On January 14, 2023, PokΓ©mon Violet crashed at 1,144 hours, giving the fish free access to the main menu. They entered inputs that opened Nintendo eShop, added 500 yen ($3.85 USD) to their owner's account, and exposed his credit card details on the livestream. 10) 11) Mutekimaru later requested a refund of the 500 yen from Nintendo. l12)
"Fish eagerly read the terms and conditions. Many of us humans don't read the terms of service, but fish are smarter than we are"
- caption from Mutekimaru in a video about the incident 12)
The fish also downloaded an N64 emulator, set up PayPal, used reward points to buy an avatar, and changed Mutekimaru's Nintendo account name to
"ROWAWAWA*". 13, After about seven hours, their movements shut down the Switch. 14)

GBE | Hemoglobin-Gene Cluster Deletions in Antarctic White-Blooded Icefishes Facilitated by Transposable Elements

Analyzing numerous genome assemblies of notothenioid fishes, Desvignes et al. demonstrated that in Antarctic white-blooded icefishes, the only vertebrates living without hemoglobin, the two hemoglobin gene clusters were lost independently from one another by different genomic mechanisms, although both mechanisms incriminate transposable and repeat-like elements.

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/...

Despite the rearrangements, we find evidence of past hybridisation throughout the evolutionary history of these radiations. Multiple species show strongly admixed ancestries, indicating that hybridisation may have facilitated their evolution. This is something we are currently investigating more.
