The New York Times allegedly paid someone to “hack” OpenAI’s models via prompting

Posted by in categories: law, robotics/AI

OpenAI is accusing the New York Times of “hacking” its products in the ongoing copyright dispute.

In a legal filing, OpenAI claims that an individual paid by the Times used “deceptive prompts” to create copies of NYT articles. These prompts would violate OpenAI’s terms of service.

The NYT demonstrated that OpenAI’s GPT models could generate copies of NYT articles when it filed a lawsuit against OpenAI for copyright infringement.

Possibly habitable Trappist-1 exoplanet caught destroying its own atmosphere

Posted by in category: space

Trappist-1e is the fourth planet from the red dwarf star at the heart of this fascinating planetary system of rocky worlds. Astronomers have previously discovered that Trappist-1b, the closest exoplanet to the star, seems to have already lost its atmosphere.

The team thinks voltage-driven Joule heating could also be impacting Trappist-1f and Trappist-1g, stripping them of their atmospheres as well, albeit to a lesser extent than they see happening with Trappist-1e. That’s because, at 0.038 and 0.04683 times the distance between Earth and the sun from their star respectively, these planets are moving slower through the red dwarf’s stellar winds than Trappist-1e is.

“Closer-in planets of Trappist-1 will have an even more extreme fate, and further out ones a bit milder,” Garraffo said. “I would imagine that all Trappist-1 planets are going to have a hard time holding on to any atmosphere.”

Precise Recovery: Aligning Orion and Artemis II Crew for Safe Retrieval

Posted by in category: space travel

One of the most crucial steps—if not the most crucial step—in safely returning astronauts to the Earth from space is the recovery process. This can happen either on land or sea, but for NASA’s upcoming Artemis II mission, the Orion capsule will be conducting a splashdown like the Mercury, Gemini, Apollo, and currently SpaceX Dragon capsules. This is why the Artemis II crew recently participated in Underway Recovert Test 11 (URT-11) on Febraury 24, which was the 11th scheduled mockup recovery test using a mockup capsule designed to simulate the exact conditions they will endure after splashing down from their historic mission.

“Our highly choreographed recovery operations will help ensure the final phase of NASA’s first crewed mission to the Moon in more than 50 years ends as a success,” Lili Villareal, who is NASA’s landing and recovery director, said in a statement.

A First-of-Its-Kind Signal Was Detected in The Human Brain

Posted by in category: neuroscience

Scientists have identified a unique form of cell messaging occurring in the human brain, revealing just how much we still have to learn about its mysterious inner workings.

Excitingly, the discovery hints that our brains might be even more powerful units of computation than we realized.

Back in 2020, researchers from institutes in Germany and Greece reported a mechanism in the brain’s outer cortical cells that produces a novel ‘graded’ signal all on its own, one that could provide individual neurons with another way to carry out their logical functions.

James Webb Space Telescope finds ‘extremely red’ supermassive black hole growing in the early universe

Posted by in categories: cosmology, space travel

Using the James Webb Space Telescope (JWST), astronomers have discovered an “extremely red” supermassive black hole growing in the shadowy, early universe.

The red hue of the supermassive black hole, seen as it was around 700 million years after the Big Bang, is the result of the expanding universe. As the universe balloons outward in all directions, light traveling toward us gets “redshifted,” and the redshifted light in this case indicates a cloak of thick gas and dust shrouding the black hole.
