AI-Powered Brain Implant Lets Paralyzed Man Control Robotic Arm
Summary: A new brain-computer interface (BCI) has enabled a paralyzed man to control a robotic arm by simply imagining movements. Unlike previous BCIs, which lasted only a few days, this…
AI-Enhanced Chip Unravels Brain’s Neural Networks
Summary: Researchers have mapped over 70,000 synaptic connections in rat neurons using a silicon chip with 4,096 microhole electrodes, significantly advancing neuronal recording technology. Unlike traditional electron microscopy, which only…
AI vs. Human Therapists: Study Finds ChatGPT Responses Rated Higher
Summary: A new study suggests that ChatGPT’s responses in psychotherapy scenarios are often rated higher than those written by human therapists. Researchers found that participants struggled to distinguish between AI-generated…
AI Mimics Toddler-Like Learning to Unlock Human Cognition
Summary: A new AI model, based on the PV-RNN framework, learns to generalize language and actions in a manner similar to toddlers by integrating vision, proprioception, and language instructions. Unlike…
Revolutionizing Brain Diagnostics with Light and AI
Summary: A new “molecular lantern” technique allows researchers to monitor molecular changes in the brain non-invasively using a thin light-emitting probe. This innovative tool utilizes Raman spectroscopy to detect chemical…
AI Tweaks Personality Tests to Appear More Likable
Summary: Large language models (LLMs) can identify when they are being given personality tests and adjust their responses to appear more socially desirable. Researchers found that LLMs, like GPT-4, showed…
AI Mirrors Human Bias: ‘Us vs. Them’ in Language Models
Summary: AI systems, including large language models (LLMs), exhibit “social identity bias,” favoring ingroups and disparaging outgroups similarly to humans. Using prompts like “We are” and “They are,” researchers found…
Blood tests are currently one-size-fits-all − machine learning can pinpoint what’s truly ‘normal’ for each patient
If you’ve ever had a doctor order a blood test for you, chances are that they ran a complete blood count, or CBC. One of the most common blood tests…
