1. Scientists Build a Robot Controlled by Human Brain Tissue


Chinese researchers have implanted a tiny organoid made from human stem cells into a tiny robot, creating a robot that can learn to complete tasks. The brain tissue is connected to a neural interface, allowing it to pass instructions to the robot body. The goal is to study brain-computer interfaces that can act as a mediator between electrical signals in the brain and computing power.

The brainy robot is the world's first open-source brain-on-chip intelligent complex information interaction system. The researchers hope that organoids could eventually be used to repair the human brain through transplantation, such as in stroke patients. However, the research is still in its infancy, and many questions remain.

2. Generate That Tune: AI Music App Suno Launches on iOS


Suno, an AI music app, has launched on iOS after the Recording Industry Association of America sued it and rival Udio for training its data on artists' work without permission. The app works similarly to its website, generating songs from text prompts. It also allows users to use their voice for music generation, share songs, curate prompts, and find music based on mood. 

Suno version 3.5 is available for free users, with paid plans offering more credits. The app is only available in the US and iOS, with an Android version in development.

3. Japan introduces enormous humanoid robot to maintain train lines


Nintendo's president, Shuntaro Furukawa, has defended the company's stance on using generative AI technology for its games, despite concerns about intellectual property rights. Despite the potential for creativity and innovation, Furukawa acknowledges the challenges of implementing AI tools that scrape the internet for image and text data.

Despite the legal, creative, and ethical concerns surrounding AI, the gold rush around the technology shows no signs of slowing down. Nintendo's approach is seen as a step in addressing the iron law of intellectual property rights.

4. Figma pauses its new AI feature after Apple controversy


Figma, a design software company, has temporarily deactivated its AI-powered Make Designs feature due to customer feedback suggesting it resembled Apple's Weather app.

Figma CEO Dylan Field defended the company's approach to building AI tools, stating that the feature uses off-the-shelf LLMs and design systems commissioned for specific models. Field instructed his team to stop the tool until they are confident with its output.

5. Google claims new AI training tech is 13 times faster and 10 times more power efficient


Google DeepMind has developed a new method called JEST, which claims to significantly accelerate training speed and energy efficiency, yielding 13 times more performance and ten times higher power efficiency than other methods.

The method involves creating a smaller AI model that grades data quality from high-quality sources, ranking the batches by quality, and comparing that grading to a larger, lower-quality set. The JEST method is crucial for the success of AI models, as it requires expert-level research skills to curate the initial highest-grade training data.
