In today’s AI news, Elon Musk’s AI company, xAI, has officially launched its latest flagship AI model, Grok 3. Released late on February 17, 2025, Grok 3 introduces significant advancements over its predecessor, Grok 2, and aims to compete with leading AI models such as OpenAI’s GPT-4o and Google’s Gemini.

In other advancements, Replit has transformed non-technical employees at Zillow into software developers. The real estate giant now routes over 100,000 home shoppers to agents using applications built by team members who had never written code before. This breakthrough stems from Replit’s new partnership with Anthropic and Google Cloud, which has enabled over 100,000 applications on Google Cloud Run.

Then, Wu Yonghui, a prestigious “Google Fellow” who worked at the US tech giant for 17 years, recently joined TikTok owner ByteDance to lead foundational research on artificial intelligence (AI), as the firm seeks to “explore the upper limit of intelligence”. Wu now works at ByteDance’s Seed department, which the Beijing-based company started in early 2023.

Meanwhile, large companies are not adopting AI as quickly as start-ups, AWS managing director Tanuja Randery says. The gap is leading to a “two-tier” AI economy as startups outpace corporations. Citing a new report from AWS, Randery said that European startups had integrated AI at pace over the last year while larger enterprises in the region were falling behind.

A nonverbal autistic child said his first words after taking a cheap drug normally given to cancer patients.

Mason Conner of Arizona was diagnosed with autism at two-and-a-half-years-old after his mother noticed he hadn’t started talking.

After years of failed therapies and treatments, Mason’s parents met with a doctor researching experimental new therapies for autism.

“What we found was surprising: a jet stream rotates material around the planet’s equator, while a separate flow at lower levels of the atmosphere moves gas from the hot side to the cooler side,” said Dr. Julia Victoria Seidel.

What can a 3D map of an exoplanet’s atmosphere teach scientists about its weather patterns? This is what a recent study published in Nature hopes to address as an international team of researchers successfully produced the first 3D map of an exoplanet’s atmosphere, which is a groundbreaking achievement and will help scientists gain new insights into the formation and evolution of exoplanet atmospheres throughout the cosmos.

For the study, the researchers used the European Southern Observatory’s Very Large Telescope (ESO’s VLT) to observe WASP-121b, nicknamed Tylos, which is designated as an ultra-hot Jupiter that orbits its parent star in only 1.3 days (30 hours) and is located approximately 880 light-years from Earth. Due to its extremely close orbit, Tylos is tidally locked to its parent star, meaning one side is always facing it, resulting in searing temperatures on the sunlit side and incredibly cold temperatures on the far side.

In the end, the researchers successfully produced a 3D map of Tylos’ atmosphere, revealing weather patterns that include high-velocity winds carrying titanium and iron around the exoplanet, which becomes even more turbulent as the winds cross from the far side to the day side of Tylos. Additionally, this also marks the first time astronomers have produced a 3D map of an exoplanet’s atmosphere.

Will the dream of interstellar travel soon become reality? Experts have been working for some time on concepts that will one day enable us to enter foreign star systems. Until now, the vast expanses of space have always thwarted this ambitious desire – after all, even the Alpha Centauri system, which is only 4.34 light-years away, is tens of thousands of travel years away with our current means! But now NASA has presented a revolutionary propulsion technology that should get us to the star system of our dreams in just 40 years! But how does the groundbreaking Sunbeam drive work? What technical tricks will make the vast distances of the cosmos seem forgotten – and when will the first interstellar research probe leave Earth?

Elon Musk’s AI startup xAI has introduced Grok 3, the latest version of its chatbot model, which Musk describes as the most advanced AI system yet.

XAI claims Grok 3 outperforms rival AI models from Alphabet’s Google Gemini, DeepSeek’s V3, Anthropic’s Claude, and OpenAI’s GPT-4o in benchmarks for math, science, and coding.

Researchers found for the first time evidence that even microquasars containing a low-mass star are efficient particle accelerators, which leads to a significant impact on the interpretation of the abundance of gamma rays in the universe.

Our home planet is bombarded with particles from outer space all the time. And while we are mostly familiar with the rocky meteorites originating from within our solar system that create fascinating shooting stars in the night sky, it’s the smallest particles that help scientists to understand the nature of the universe. Subatomic particles such as electrons or protons arriving from interstellar space and beyond are one of the fastest particles known in the universe and known as cosmic rays.

The origins and the acceleration mechanisms of the most energetic of these cosmic particles remains one of the biggest mysteries in astrophysics. Fast-moving matter outflows (or “jets”) launched from black holes would be an ideal site for particle acceleration, but the details on how and under which conditions acceleration processes can occur are unclear. The most powerful jets inside our Galaxy occur in microquasars: systems composed by a stellar-mass black hole and a “normal” star. The pair orbit each other, and, once they are close enough, the black hole starts to slowly swallow its companion. As a consequence of this, jets are launched from the region close to the black hole.
