MIT researchers have created FibeRobo, a liquid crystal elastomer (LCE) fiber that responds to cold or hot thermal stimuli.

Imagine a fiber that changes its shape when it gets warm and being able to use this fiber to make clothes that can quickly and silently change its shape.

Researchers at Massachusetts Institute of Technology (MIT) and Northeastern University have created FibeRobo, a liquid crystal elastomer (LCE) fiber that responds to cold or hot thermal stimuli.


FibeRobo is a liquid crystal elastomer fiber that can change its shape in response to thermal stimuli. Compatible with existing textile manufacturing machinery, it could be used to make morphing textiles, like a jacket that changes its insulating properties.

Modern chips: many steps, low energy consumption.

These key requirements for a chip are summed up mathematically by the parameter TOPS/W: “tera-operations per second per watt”. This can be seen as the currency for the chips of the future. The question is how many trillion operations (TOP) a processor can perform per second (S) when provided with one watt wordpress of power. The new AI chip, developed in a collaboration between Bosch and Fraunhofer IMPS and supported in the production process by the US company GlobalFoundries, can deliver 885 TOPS/W. This makes it twice as powerful as comparable AI chips, including a MRAM chip by Samsung. CMOS chips, which are now commonly used, operate in the range of 10–20 TOPS/W. This is demonstrated in results recently published in Nature.

In-memory computing works like the human brain.

OpenAI’s CEO, Sam Altman, spent a good part of the summer on a weeks-long outreach tour, glad-handing politicians and speaking to packed auditoriums around the world. But Sutskever is much less of a public figure, and he doesn’t give a lot of interviews.

He is deliberate and methodical when he talks. There are long pauses when he thinks about what he wants to say and how to say it, turning questions over like puzzles he needs to solve. He does not seem interested in talking about himself. “I lead a very simple life,” he says. “I go to work; then I go home. I don’t do much else. There are a lot of social activities one could engage in, lots of events one could go to. Which I don’t.”

But when we talk about AI, and the epochal risks and rewards he sees down the line, vistas open up: “It’s going to be monumental, earth-shattering. There will be a before and an after.”
