AI researchers are creating novel “benchmarks” to help models avoid real-world stumbles.

Trained on billions of words from books, news articles, and Wikipedia, artificial intelligence (AI) language models can produce uncannily human prose. They can generate tweets, summarize emails, and translate dozens of languages. They can even write tolerable poetry. And like overachieving students, they quickly master the tests, called benchmarks, that computer scientists devise for them.

That was Sam Bowman’s sobering experience when he and his colleagues created a tough new benchmark for language models called GLUE (General Language Understanding Evaluation). GLUE gives AI models the chance to train on data sets containing thousands of sentences and confronts them with nine tasks, such as deciding whether a test sentence is grammatical, assessing its sentiment, or judging whether one sentence logically entails another. After completing the tasks, each model is given an average score.

In partnership with NASA, Sandia researchers design reliable and resilient microgrids that could sustain astronauts, mining and fuel processing on the moon.

Performed by Moxie — the Mars Oxygen In-Situ Resource Utilization Experiment — the strategy definitely incited hope for extraterrestrial survival. Future human missions could take versions of Moxie to Mars instead of carrying oxygen from Earth to sustain them.

But, Moxie is powered by a nuclear battery onboard.

“In the near future, we will see the crewed spaceflight industry developing rapidly,” said Yingfang Yao, a material scientist at Nanjing University.

SpaceX’s Crew Dragon will streak through Earth’s atmosphere

“Teams from @NASA & @SpaceX now are targeting #Crew3 undocking at 1:05 am Thurs, May 5 from @Space_Station. Splashdown off of Florida’s coast is planned about 12:37 am Fri, May 6. The new undocking time allows for shorter phasing & more time to review the latest forecast info,” said Lueders, in the Wednesday tweet.

The U.S. Department of Treasury today sanctioned cryptocurrency mixer Blender.io used last month by the North Korean-backed Lazarus hacking group to launder funds stolen from Axie Infinity’s Ronin bridge.

In the wake of the attack, Sky Mavis (the bridge’s creator) revealed that hackers breached the Ronin bridge on March 23 to steal 173,600 Ethereum and 25.5M USDC tokens in two transactions worth $617 million at the time, the largest cryptocurrency hack in history.

The previous most significant theft of cryptocurrency was the $611 million Poly Network hack in August 2021.

The earliest possible flight of the Space Launch System rocket is in mid-summer.

After a third attempt at a wet dress rehearsal failed, NASA sent Artemis 1 back to the VAB — and set back the anticipated launch date by three months.

In recent years, developers have created a wide range of sophisticated robots that can operate in specific environments in increasingly efficient ways. The body structure of many among these systems is inspired by nature, animals, and humans.

Although many existing robots have bodies that resemble those of humans or other animal species, programming them so that they also move like the animal they are inspired by is not always an easy task. Doing this typically entails the development of advanced locomotion controllers, which can require considerable resources and development efforts.

A recent study of Jupiter’s moon, Europa, showed that radiolytic oxidants made at the surface of its ice can travel to the ocean beneath its ice shell, according to a team of researchers led by the University of Texas at Austin. This means that the icy moon could be suitable for alien life.
