Swimming can take a lot of muscle. But as MIT engineers have found, even a single layer of muscle cells can power through water if designed right. In a paper published Sept. 28 in the journal Advanced Functional Materials, the team presents a design for a thin, muscle-powered swimming robot. The “skeleton” of the aquabot is made from a film of gel about the length and width of a stick of gum. The two halves of the gel form the bot’s “fins.” Each fin is covered with a layer of live muscle cells much thinner than a single strand of hair. The cells are genetically engineered to twitch in response to light.Swimming can take a lot of muscle.

A Venus flytrap closes its leaves to trap prey when it senses a stimulus. Taking inspiration from this plant, KAIST researchers have combined the roles of skin that senses approaching objects and muscle that grasps them in a single soft material. When an electrically charged object comes near, ions inside the material move and produce an electrical signal.A Venus flytrap closes its leaves to trap prey when it senses a stimulus.

As more people turn to LLMs for advice on interpersonal matters, the ethical foundations of the tools’ replies increasingly have the power to shape individual lives and, at scale, the social fabric itself.As more people turn to LLMs for advice on interpersonal matters, the ethical foundations of the tools’ replies increasingly have the power to shape individual lives and, at scale, the social fabric itself.Machine learning & AI[#item_full_content]
Recent advances in generative artificial intelligence (AI), particularly large language models, which underpin many contemporary AI systems, have made natural-language interaction with AI characters increasingly feasible.Recent advances in generative artificial intelligence (AI), particularly large language models, which underpin many contemporary AI systems, have made natural-language interaction with AI characters increasingly feasible.Machine learning & AI[#item_full_content]
