Summary: Researchers developed an artificial intelligence model that accurately determines the sex of individuals based on brain scans, with over 90% success. This breakthrough supports the theory that significant sex differences in brain organization exist, challenging long-standing controversies. The AI model focused on dynamic MRI scans, identifying specific brain networks—such as the default mode, striatum, …
Men’s brains tend to be larger than women’s, which makes them difficult to compare Sergiy Tryapitsyn / Alamy Are men’s and women’s brains all that different? A new way of investigating this question has concluded that they are – but it takes artificial intelligence (AI) to distinguish between them. The question of whether we can …
Summary: Dr. Roman V. Yampolskiy, an AI Safety expert, warns of the unprecedented risks associated with artificial intelligence in his forthcoming book, AI: Unexplainable, Unpredictable, Uncontrollable. Through an extensive review, Yampolskiy reveals a lack of evidence proving AI can be safely controlled, pointing out the potential for AI to cause existential catastrophes. He argues that …
Summary: Researchers developed an AI algorithm that, by analyzing brain scans and clinical information, can predict within a week whether an antidepressant will work for patients with major depression disorder. This method could potentially avoid unnecessary prescriptions of sertraline, a commonly used antidepressant, by identifying non-responders early, thus offering better patient care and reducing side …
Elon Musk’s Neuralink company has performed its first implant in a human brain as it develops a technology aimed at helping those with severe paralysis. In a post on social media sharing the update, Musk said: “The first human received an implant from Neuralink yesterday and is recovering well.” He added that “initial results show …
Summary: Researchers discovered in mice that passive exposure, alongside active training, can significantly enhance the learning process. This study demonstrates how passive exposure to stimuli like sounds or languages helps the brain to form foundational representations, making active learning more efficient. The findings, which align with prior research in humans, suggest that combining low-effort passive …
Summary: Researchers made a significant discovery using an artificial neural network model, suggesting that musical instinct may emerge naturally from the human brain. By analyzing various natural sounds through Google’s AudioSet, the team found that certain neurons in the network selectively responded to music, mimicking the behavior of the auditory cortex in real brains. This …
Summary: A new study explores how infants and toddlers acquire language. The research challenges preconceived notions about language development, particularly in low-income families, by analyzing daylong audio recordings of 1,001 children from diverse backgrounds. Findings reveal early comprehension begins around 6-7 months, and significant improvements in language understanding occur around a child’s first birthday. The …
Summary: A new study reveals limitations in the current use of mathematical models for personalized medicine, particularly in schizophrenia treatment. Although these models can predict patient outcomes in specific clinical trials, they fail when applied to different trials, challenging the reliability of AI-driven algorithms in diverse settings. This study underscores the need for algorithms to …
Summary: Researchers made a breakthrough in understanding the universality of emotions across languages by using colexification analysis, a method of studying word associations. Their study identifies four central emotion-related concepts – “GOOD,” “WANT,” “BAD,” and “LOVE” – as having the highest number of associations with other emotional words in multiple languages. This finding aligns with …
