Humans Are Erasing Billions of Years of Data From Ancient Meteorites

A popular and easy method for validating whether or not a chunk of rock is a meteorite, and what kind of meteorite it is, has been inadvertently erasing invaluable information locked inside.

The use of rare-earth magnets such as neodymium erases and overwrites the magnetic record locked inside ferromagnetic minerals in meteorites, scientists from MIT in the US and Paris Cité University in France found. Since many meteorites that fall to Earth have a significant iron content, this means we’re losing important data on the way magnetic fields in space have altered these meteorites over billions of years.

Meteorites provide invaluable records of planetary formation and evolution. Studies of their paleomagnetism have constrained accretion in the protoplanetary disk, the thermal evolution and differentiation of planetesimals, and the history of planetary dynamos.

Google to give its search engine an AI makeover by the end of the year

World’s biggest search engine threatened by competition from Microsoft’s Bing.

Google is synonymous with the internet. Millions throng to the search engine every day. From catching up on what’s happening in the world to discovering how to dye your cat green, Google has the answer to everything.

So, it was only a matter of time before the tech giant integrated its widely used search engine with artificial intelligence. This was inevitable, with almost all major tech companies dashing to cash in on the expanding AI space. It has already launched an AI-powered chatbot called Bard, similar to ChatGPT.

Chinese scientists let AI control satellite, it takes ‘closer look’ at specific spots in India, Japan

According to Chinese state media, a team of researchers from Wuhan University allowed an AI to take control of a satellite for 24 hours to see what it would do.

According to Chinese state media, the South China Morning Post.

Chinese scientists said that they were able to conduct a “landmark experiment” by allowing an artificial intelligence (AI) machine to take full control of a satellite temporarily in near-Earth orbit to test its behaviour in space.

Qimingxing 1, a small Earth observation satellite, was controlled by the AI for 24 hours, and it functioned without any human order, assignment or intervention, a paper published in the journal Geomatics and Information Science of Wuhan University stated.

Notably, the AI spotted a few places on Earth and ordered the satellite to “take a closer look”.

How to Summon Entities: A Glimpse into GPT-4 through the lens of Jungian Psychology & Jungian Archetypes

Introduction.
The GPT-4 language model is a remarkable AI technology that can generate human-like text.

While it lacks certain human psychological factors, such as individuation and the Jungian Shadow, GPT-4 demonstrates a fascinating awareness of archetypes and their role in shaping human behavior.

This article delves into GPT-4’s understanding of Jungian psychology and explores the implications of archetypes as a language-space phenomenon.

Lightning Bolt Deposits a Strange Mineral Never Seen on Earth Before

A lightning bolt that struck a tree on Florida’s west coast has produced a fascinating type of phosphorus material we haven’t seen on Earth before: one that could represent a whole new mineral group, bridging the gap between space minerals and minerals found on Earth.

The material, which is a close match for calcium phosphite (CaHPO3), was found trapped inside a fulgurite – a “metal glob” formed by the reaction of the ultra-hot lightning bolt with the sand around the roots of its target.

These ‘fossilized lightning’ fulgurites often occur when lightning strikes certain types of sand, silica, and rock. What’s much less common is to find something so unique hidden inside one of these structures.

Mixed Reality Tracking System For Future Pilot Training

Vrgineers and Advanced Realtime Tracking demonstrate the combination of XTAL 3 headset and SMARTTRACK3/M in a mixed reality pilot trainer. The partnership between these two technological companies started in 2018. At IT2EC 2023 in Rotterdam, the integrated SMARTTRACK3/M into an F-35-like Classroom Trainer manufactured and delivered to USAF and RAF will be for display. This unique combination of the latest ART infrared all-in-one hardware and Vrgineers algorithms for cockpit motion compensation creates an unseen immersion for every mixed reality training. One of the challenges in next-generation pilot training using virtual technology and motion platforms is the alignment of the pilot’s position in the cockpit. By overcoming this issue, the simulator industry is moving forward to eliminate the disadvantages of simulated training.

“We are continuously working on removing the technological challenges of modern simulators, one of which is caused by front-facing camera position distance from users’ eyes. We are developing advanced algorithms for motion compensation to minimize the shift between virtual and physical scene, making experience realistic. The durability and compact size of SMARTTRACK3/M, which was optimized for using in cockpits, allows us as training device integrator to make it a comprehensive part of a simulation,” says Marek Polcak, CEO of Vrgineers.

“This is the application SMARTTRACK3/M was designed for., We have taken the proven hardware from the SMARTTRACK3 and adapted it to the limited space available. As a result, we have the precision and the reliability of a seasoned system in a form factor fitting to simulator cockpits” says Andreas Werner, business development manager for simulations at ART.

How much of the Universe can humanity reach?

Beyond our own Milky Way galaxy, there are physical limits on our access to the Universe. In this new video from PBS Space Time, we explore the absolute limit of our future view of the Universe, and of the Universe’s ability to influence us.

We humans have always been explorers. The great civilisations that have arisen across the world are owed to our restless ancestors. These days, there’s not much of Earth left to explore. But if we look up, there’s a whole Universe out there waiting for us. Future generations may one day explore the cosmos and could even settle entire other galaxies.

However, there is a fundamental limit to how much of the Universe we can expand into. So, just how big could humanity get? Matt O’Dowd, astrophysicist and host of PBS Space Time, looks at the obstacles that our descendants could face in the very distant future.

Amazon throws its hat into generative AI space, launches Bedrock

Bedrock allows its users to build and scale generative AI applications like chatbots.

Becoming the latest actor to join the generative AI space race, Amazon Web Services (AWS) has launched Bedrock. Not to be confused with OpenAI’s ChatGPT or Google’s Bard which are AI-powered chatbots.

What Bedrock does is allowing users to build and scale generative AI applications such as chatbots, text generation, image generation using language prompts, etc. There’s a range of pre-trained models that the users can customize and embed their own data into and then integrate and deploy in applications using the AWS tools.
