Fake blood pumps life into this robotic fish

Researchers have engineered a robotic lionfish with synthetic arteries, similar to those found in a human’s circulatory system. The fish “blood” that runs through it serves as both the robot’s power source and controls its movement. The findings, published Wednesday in Nature, may propel the new wave of soft robots, in which inventors seek to improve lifelike automated machines for human connection.

Synthetic blood vessels in a new robotic fish could improve the technology needed to make lifelike robots run longer.

Schizophrenia Identified in 60 Seconds via Visual Fixation

Summary: Researchers have identified spatial and temporal abnormalities in spontaneous fixational saccades as a potential biomarker for cognitive and positive symptoms in schizophrenia. Researchers combined patient data of fixational eye movement recorded over 60 seconds with machine learning technology, which was able to determine schizophrenia with 85% accuracy. This discovery suggests that fixational saccades could serve as an easily obtainable complementary diagnostic tool for the condition.

In a study published online in the Schizophrenia Bulletin, researchers from Dr. Wang Wei’s lab at the Center for Excellence in Brain Science and Intelligence Technology of the Chinese Academy of Sciences, and Dr. Wang Jijun’ team at Shanghai Mental Health Center, Shanghai Jiao Tong University School of Medicine, demonstrated spatial and temporal abnormalities of spontaneous fixational saccades and their correlates with positive and cognitive symptoms in schizophrenia, suggesting that fixational saccades are a promising and easily obtainable biomarker for cognitive and positive symptoms and for complementary diagnosis in schizophrenia.

NVIDIA Canvas App: AI-Powered Painting

With all the controversy surrounding AI art, I’m surprised that NVIDIA is so rarely discussed. Unlike other AI art technologies, NVIDIA facilitates drawing landscapes in an interactive fashion. You sketch out rough blobs and then the AI converts your shapes into rocks, grasses, dirt, trees, and other selectable material types. I think that this kind of tool deserves much more attention since it empowers human artists to create with AI as a partner and gives us more creative control over the final result. Sure, NVIDIA itself is somewhat limited, but the principle of it is very compelling and I can easily envision people developing lots of improved versions that can draw more than just landscapes. I think it is surprising that this kind of approach has not caught on, but perhaps there are economic reasons that I’m not aware of which explain the relative lack of interactive AI art tools.

AI Emulates Brain’s Memory Replay, Uncovering How We Learn

A new study focuses on the role of the hippocampus, a brain region important for memory, and its place cells which “replay” neuronal sequences.

The researchers built an artificial intelligence model to better understand these processes, discovering that sequences of experiences are prioritized during replay based on familiarity and rewards.

The AI agent was found to learn spatial information more effectively when replaying these prioritized sequences, offering valuable insight into the way our brains learn and process information.

AI runs 10,000 experiments a day on bacteria to speed up discoveries

Scientific work often involves sifting through enormous amounts of data, a task that’s overwhelmingly mundane for humans but a piece of cake for artificial intelligence. A new platform dubbed BacterAI can conduct as many as 10,000 experiments per day to teach itself – and us – more about bacteria.

The human body is home to trillions of microbes, covering almost every surface inside and out. Many of them are vital to specific bodily functions, while many others make you sick. Research continues to uncover how inextricably linked our overall health is to our microbiomes, but managing and exploring the data involved remains a daunting task.

“We know almost nothing about most of the bacteria that influence our health,” said Paul Jensen, corresponding author of the new study. “Understanding how bacteria grow is the first step toward reengineering our microbiome.”

Study presents large brain-like neural networks for AI

In a new study in Nature Machine Intelligence, researchers Bojian Yin and Sander Bohté from the HBP partner Dutch National Research Institute for Mathematics and Computer Science (CWI) demonstrate a significant step towards artificial intelligence that can be used in local devices like smartphones and in VR-like applications, while protecting privacy.

They show how brain-like neurons combined with novel learning methods enable training fast and energy-efficient spiking on a large scale. Potential applications range from wearable AI to and Augmented Reality.

While modern artificial neural networks are the backbone of the current AI revolution, they are only loosely inspired by networks of real, biological neurons such as our brain. The brain however is a much larger network, much more energy-efficient, and can respond ultra-fast when triggered by external events. Spiking neural networks are special types of neural networks that more closely mimic the working of biological neurons: the neurons of our nervous system communicate by exchanging electrical pulses, and they do so only sparingly.
