@nature.com the anthropomorpizing language of this article as well as the equating of agentic loops with actual employees/scientists without any evidence of that conjecture is deeply insulting to scientists and scientific rigor, respectively. 🧪🧬🖥️

This went a different way than I though based on the garbage headline, and gets there in the end: you should assume the company being sued for IP theft is probably doing it to you too. But why would they treat this as a "wake-up call"? Also, props to the Clay Institute for integrity.
OpenAI says it has verified its proof using a programming language called Lean. The Clay Mathematics Institute, whose scientific headquarters are in Oxford, UK, says it will consider whether a solution is valid only after the results have been published in a peer-reviewed publication and been further vetted by the community.

Absolutely brutal to the author and I love it. Turns out "there's no clear definition of intelligence" is just tech's red badge of illiteracy.
The AI research community is extremely insular in a lot of ways,” Jager said. “For example, none of these guys know anything about the biological origins of words like ‘agency’ and ‘intelligence’ that they use all the time. They have absolutely frighteningly no clue. And I'm talking about Geoffrey Hinton and top people, Turing Prize winners and Nobel Prize winners that are absolutely marvelously clueless about both the conceptual history of these terms, where they came from in their own history of AI, and that they're used in a very weird way right now. And I'm always very surprised that there is so little interest. I guess it's just a high pressure environment and they go ahead developing things they don't have time to read.

A fundamental principle of scientific method is axiomatic construction of new principles on the collective framework of prior expertise. Hallucinated references are not typos, they are fabricated evidence, which is unambiguous academic fraud. Negligence is not an excuse. 🧪 doi.org/10.1038/d415...
Scholars are still debating whether and when hallucinated citations should be considered a form of research misconduct. Even major problems can happen unintentionally. For example, authors might use LLMs in a rush to format their reference list, unaware that AI has rephrased the citations, changed DOIs or added made-up references. Policies on AI use differ across journals. Most publishers require authors to disclose the use of AI, although what specific uses need to be disclosed varies. Policies also require human oversight of AI tools. Failing to verify their output could represent a lack of scientific rigour, according to several researchers who spoke to Nature.

This is a fascinating hypothesis that places ASD/SCZ in the context of the evolution of sapience with the rapid expansion of layer 2/3 neurons under fitness selection. That might inform an exposure risk, but I think ties that spectrum to the existence of humanity itself. 🧪🧬🖥️ doi.org/10.1093/molb...
Although our results strongly suggest natural selection for down-regulation of ASD-linked genes, the reason why this conferred fitness benefits to our ancestors remains an open question. Answering this question is difficult in part because we do not know what human-specific features of cognition, brain anatomy, and neuronal wiring gave our ancestors a fitness advantage, but we can speculate about two general classes of evolutionary scenarios. First, down-regulation of ASD-linked genes may have led to uniquely human phenotypes. For example, haploinsufficiency of many ASD-linked genes is associated with developmental delay (Zug and Uller 2022), so their down-regulation could have contributed to the slower postnatal brain development in humans compared to chimpanzees. Alternatively, capacity for speech production and comprehension is unique to or greatly expanded in humans and often impacted in ASD and SCZ (Chang et al. 2022; Vogindroukas et al. 2022). If down-regulation of ASD-linked genes conferred a fitness advantage by slowing postnatal brain development or increasing the capacity for language, that could result in the signal of positive selection we observed.

On the other hand, the down-regulation we observed may have been compensatory and reduced the negative effects of some other human-specific trait or traits. For example, the ratio of excitatory and inhibitory synapses on pyramidal neurons is fairly constant between humans and rodents despite massive differences in brain and neuron size (DeFelipe et al. 2002). In addition, excitatory-inhibitory imbalance is a leading hypothesis for the circuit basis of ASD (Sohal and Rubenstein 2019). Overall, more work is needed to understand how natural selection acting on the expression of ASD-linked genes in the human lineage may have shaped human phenotypes.

Good article, but the semantics of "thinking without a thinker" imply (1) it is trying to solve and (2) some level of feedback learning. That implies agency in a feed-forward model effectively doing linguistic regression that is (mis)aligned with, but not equal to, inductive reasoning.

Nature, please stop hyping the Mechanical Turk. Humans at the AI Scientist built this non-agent (at best a workflow). They did it with full knowledge they are using works under CC-BY which means they intended to violate those terms. Central to authorship is culpability. Thus a bot can't author.
Krueger, who is at the University of Montreal in Canada, told Nature that the related works should have been cited, but that he “wouldn’t be surprised to see human researchers reinvent this and miss previous work” too. “I think this AI system and others are not capable of achieving academic standards for referencing related work,” he said, adding that the AI paper was “extremely low quality overall”. But he wasn’t sure whether the word plagiarism should be applied, because he feels that term implies that the person (or AI tool) reusing methods was aware of earlier work, but chose not to cite it.

Of course, our research has important limitations. Although MAI-DxO excels at tackling the most complex diagnostic challenges, further testing is needed to assess its performance on more common, everyday presentations. *the bad part* Clinicians in our study worked without access to colleagues, textbooks, or even generative AI, which may feature in their normal clinical practice.  This was done to enable a fair comparison to raw human performance.

This kind of reasoning has the potential to reshape healthcare. *the bad part* AI could empower patients to self-manage routine aspects of care and equip clinicians with advanced decision support for complex cases.

A major problem in grading LLMs is that peer review is qualitative. Doing stats on opinions of peer-review doesn't solve that. I remember a news piece where a room of people read identical horoscopes they thought were tailored to them. Was it accurate? Most said yes.🧪 www.nature.com/articles/d41...
Mixed Reviews: Around 300 researchers asked to rate a large language model's ability to provide feedback on manuscripts found comments to be helpful and in alignment with comments from human reviewers. Half also said they would use the system again. But compared with human reviewers, most researchers also thought the AI feedback was less specific and tended to be less helpful.
