Body scan companies say they can diagnose cancer faster and that AI can make it cheaper. But there’s a gap between that dream and the medical community’s reality.

ChatGPT often won’t defend its answers, even when it is right
ChatGPT may do an impressive job at correctly answering complex questions, but a new study suggests it may be absurdly easy to convince the AI chatbot that it’s in the wrong.
A team at Ohio State University challenged large language models (LLMs) like ChatGPT to a variety of debate-like conversations in which a user pushed back when the chatbot presented a correct answer.
Through experimenting with a broad range of reasoning puzzles, including math, common sense, and logic, the study found that when presented with a challenge, the model was often unable to defend its correct beliefs and instead blindly believed invalid arguments made by the user.
Synapses without tension fail to fire in an in vitro network of hippocampal neurons
Neurons in the brain communicate with each other at their synapses. It has long been understood that this communication occurs through biochemical processes. Here, we reveal that mechanical tension in neurons is essential for communication. Using in vitro rat hippocampal neurons, we find that 1) neurons become tout/tensed after forming synapses resulting in a contractile neural network, and 2) without this contractility, neurons fail to fire. To measure time evolution of network contractility in 3D (not 2D) extracellular matrix, we developed an ultrasensitive force sensor with 1 nN resolution. We employed Multi-Electrode Array and iGluSnFR, a glutamate sensor, to quantify neuronal firing at the network and at the single synapse scale, respectively. When neuron contractility is relaxed, both techniques show significantly reduced firing. Firing resumes when contractility is restored.
Welcome to the Cyborg Era: Brain Implants Transformed Lives This Year
This year gave rise to an incredible mix of brain implants that can record, decode, and alter brain activity.
It sounds like déjà vu—brain-machine interfaces also lived rent free in my head in last year’s roundup, but for good reason. Neuroscientists are building increasingly sophisticated and flexible electronic chips that seamlessly integrate machine intelligence with our brains and spinal cords at record-breaking speed. What was previously science fiction—for example, helping paralyzed people regain their ability to walk, swim, and kayak—is now reality.
This year, brain implants further transformed people’s lives. The not-so-secret sauce? AI.

NEW Alter 3 GPT4 AI Robot w/ 43 Axes (DEMOS SEVERAL NEXT GEN ABILITIES)
Alter 3 has just been unveiled by the University of Tokyo and its powered by GPT-4, capable of human-like activities and interpreting verbal instructions. Researchers at the Technical University of Munich developed a self-aware robot with proprioception, enhancing its movement and interaction capabilities. The University of Southern California introduced RoboCLIP, an algorithm that trains robots to perform tasks in new environments with minimal instruction. Intel Labs and partners created advanced motor control for robots using hierarchical generative models, significantly improving their ability to perform complex tasks.\

Unitree enters the humanoid robot marketplace, with the bipedal H1
It was just this week that we told you about Unitree’s latest quadruped robot, the B2. Well, the Chinese company has also announced its first-ever humanoid bipedal robot, the Unitree H1.
With a planned price tag of under US$90,000, the H1 is intended to rival other humanoid bots such as those made by Tesla, Figure and Agility Robotics. As far as basic specs go, it stands 1,805 mm tall (71 in), weighs about 47 kg (104 lb) and can carry a payload of up to 30 kg (66 lb).
Joints in the hip, knee and ankle give each leg a total of five degrees of freedom, while joints in the shoulder and elbow give each arm a total of four degrees. Unitree’s own M107 motors deliver 360 Nm (266 lb ft) of torque at each joint. Flexible fingers are reportedly in the works.
