Quantum-gravitational mechanism could explain the universe’s homogeneity

Our universe is known to be remarkably homogeneous and isotropic. This essentially means that matter is distributed evenly throughout the universe and that it looks almost the same in all directions.

Physics theories, however, predict that in its early days, the universe may have been far less orderly, with different regions expanding at varying rates. Yet how the universe could have evolved from this potentially uneven beginning into the smoothness we observe today remains unclear.

Researchers at Baylor University, Jiangxi Normal University, State University of Rio de Janeiro and Universidade Federal Fluminense recently delineated a mechanism that could explain how the universe shifted from early unevenness (i.e., anisotropy) to its current homogeneity. Their theoretical paper, published in Physical Review Letters, models the evolution of the early universe using a framework known as the modified loop quantum cosmology (mLQC-I) model.

Neutron-based technique reveals uneven lithium flow in batteries

A neutron-based mapping technique has been used to track the movement of lithium ions in real time inside a functioning all-solid-state battery.

Researchers at the Institut Laue-Langevin (ILL) in France discovered unexpected structural complexities, which could inform the design of safer, more efficient solid-state batteries.

The operando neutron powder diffraction technique was used to peer inside the battery interface. Interestingly, the experiment revealed a chaotic structure within the electrode, showing that lithium doesn’t flow through the battery nearly as smoothly as previously thought.

Scientists to track critically endangered tope sharks in the Solent

One of Britain’s largest and most endangered sharks is to be tracked through the busy waters of the Solent, following a £230,000 research grant awarded to scientists at the University of Portsmouth – part of the largest ever government investment in recovering England’s threatened wildlife.

The tope shark, listed as critically endangered on the IUCN Red List, can grow to nearly two metres in length, yet remains largely invisible to the public despite living in some of the UK’s most heavily trafficked coastal waters.

Facing sustained pressure from overfishing, bycatch, habitat loss and wider environmental change, tope populations have declined significantly across their global range.

NVIDIA Nemotron Achieves Benchmark-Leading Performance With LangChain Deep Agents Harness

NVIDIA Nemotron 3 Ultra is offering leading performance at lower cost than top closed models with the largest and most widely adopted AI agent orchestration platform. LangChain tuned its Deep Agents harness for NVIDIA Nemotron 3 Ultra, achieving the highest accuracy among open models, while completing more tasks at higher throughput and running at 10x

Pioneers of Aeronautical Engineering: Dale Reed — Father of the Lifting Bodies

Dale Reed transformed aerospace research through his pioneering work on lifting bodies and remotely piloted research vehicles. His innovations laid the foundation for the Space Shuttle’s design and advanced unmanned flight testing, making him one of NASA’s most influential flight research engineers.

Extremely Large Telescope reaches a major milestone

The Extremely Large Telescope just passed a serious milestone while coming together. But it’s not done yet; the immense telescope is about to get even larger.

The European Organization for Astronomical Research in the Southern Hemisphere (ESO)’s Extremely Large Telescope is under construction on a mountaintop in Chile.

Coining the Technological Singularity

Everybody writes about the Singularity now. Almost nobody knows where the word was born.

Not in a lab. Not in a think tank. In the January 1983 issue of Omni magazine, where a mathematician and science fiction writer named Vernor Vinge put a name to the thing the rest of us are still trying to survive.

Think about that. Four decades before ChatGPT, before the AI arms race, before every futurist and their algorithm started forecasting the end of the human era, the framework already existed. Vinge saw the curve. He just needed a word for the point where it goes vertical.

Today, that word is inescapable. Write about AI, about the future of work, about what happens to humanity when the machines get smarter than us, and you are writing about the Singularity, whether you use the term or not. Refuse to, and you owe your reader an explanation for why not. So you are still writing about it.

Thanks to Josh Calder, who dug out and scanned the original page, you can see the exact moment the term entered our vocabulary. A little piece of digital history, hiding in plain sight for 40 years.

Where do you think we are on Vinge’s curve right now? #Singularity #ArtificialIntelligence #Futurism.
