A team of researchers at the Korean Advanced Institute of Science (KAIST) has succeeded in developing a new artificial muscle using graphene-liquid crystal composite fibers.

The team, led by Professor Kim Sang-ouk of the Department of Materials Science and Engineering, stressed that the artificial muscle was found to be the most similar to human muscle among those reported to the scientific community so far.

Also, the artificial muscle showed up to 17 times stronger strength when compared to human muscles.

OpenAI is the developer of a new AI program called ChatGPT, capable of writing and conversing very much like a human.


On the first task, the general impression from teachers was that at best it provided a framework but not the details for lesson planning. The same was said about the letter-writing capabilities of the tool, and the composing of a rubric. On providing feedback on student work, the response was less than impressed with the comments and grading. And on writing a letter of recommendation, the comments stated that what ChatGPT came up with was “far too generic.” So all in all, the current version of ChatGPT as a teaching aid seems underwhelming.

On the student work side, ChatGPT is far more problematic. Because ChatGPT can compose the kind of content it produced for me in the above example, teachers have expressed concern that the tool makes it easy for students to submit work they didn’t write.

When OpenAI made it publicly available in November of last year, the New York City School Board blocked access to it on its networks and computers. A Princeton University student created an app called GPTZero aimed at the responsible use of AI in education and capable of detecting ChatGPT-written documents.

What The Internet Looked Like In The 1990s | Flashback | NBC News.

Summary: Researchers develop a novel tool that allows for the study of the communication of microbes in the gastrointestinal tract and the brain.

In the past decade, researchers have begun to appreciate the importance of a two-way communication that occurs between microbes in the gastrointestinal tract and the brain, known as the gut–brain axis.

Even with their previous prices, the Tesla Model S and Model X are already formidable in their respective segments. But with their recently adjusted costs, Tesla’s two flagship electric vehicles just became a lot more competitive.

Following a recent round of price adjustments, the Tesla Model S and Model X are now more affordable. The flagship all-electric sedan now starts at $94,990 for its Dual Motor AWD variant. Previously, the vehicle started at $104,990. The Model S Plaid, on the other hand, now starts $114,990, a notable drop from its previous price of $135,990.

Every year, the Stanford Institute for Human-Centered Artificial Intelligence (HAI) puts out its AI Index, a massive compendium of data and graphs that tries to sum up the current state of artificial intelligence. The 2022 AI Index, which came out this week, is as impressive as ever, with 190 pages covering R&D, technical performance, ethics, policy, education, and the economy. I’ve done you a favor by reading every page of the report and plucking out 12 charts that capture the state of play.

It’s worth noting that many of the trends I reported from last year’s 2021 index still hold. For example, we are still living in a golden AI summer with ever-increasing publications, the AI job market is still global, and there’s still a disconcerting gap between corporate recognition of AI risks and attempts to mitigate said risks. Rather than repeat those points here, we refer you to last year’s coverage.

Wind turbine blades are recycled into reinforcement fiber that increases the strength and overall durability of concrete.

Wind turbines are great for producing energy but become quite wasteful once their lifetime has expired, as the materials used to construct them simply don’t biodegrade very well.

One company is seeking to do something about that according to a report by electrek published on Thursday.

They have a lifespan of around 20–25 years, and once they are discarded, their massive, glass or carbon fiber-reinforced blades often end up in landfills.
