Physicists confirm quantum entanglement persists between top quarks, the heaviest known fundamental particles

Posted by in categories: particle physics, quantum physics

An experiment by a group of physicists led by University of Rochester physics professor Regina Demina has produced a significant result related to quantum entanglement—an effect that Albert Einstein called “spooky action at a distance.”

MacOS Sequoia brings iPhone remote control and Passwords app

Posted by in categories: mobile phones, robotics/AI

Apple’s first reveal of the new macOS Sequoia includes a way to remote control your iPhone directly from the Mac, and a new Apple Passwords app.

Announced in the WWDC 2024 keynote, macOS 15 is called macOS Sequoia, and as expected, it brings AI — or Apple Intelligence — to every platform and practically every feature.

Across macOS Sequoia and Apple’s other platforms, users can write, summarize, and proofread text almost system-wide with Writing Tools. It will be able to generate sketches, animations, or illustrations with Image Playground, which is built into apps including Messages — and has its own brand-new app too.

NVDIA Nemotron

Posted by in category: computing

Open synthetic data generation pipeline for training LLMs.

We release the Nemotron-4 340B model family, including Nemotron-4-340B-Base, Nemotron-4-340B-Instruct, and Nemotron-4-340B-Reward. Our models are open access under the NVIDIA Open Model License Agreement, a permissive license similar to Apache 2.0. These models perform competitively to open access models on a wide range of evaluation benchmarks, and were sized to fit on a single DGX H100 with 8 GPUs when deployed in FP8 precision.

Ask Ethan: Is the Universe finite or infinite?

Posted by in category: cosmology

The Universe’s history, from cosmic inflation to the Big Bang to the present, is known. But whether it’s infinite or not is still a mystery.

High-speed baby stars circle the supermassive black hole Sgr A* like a swarm of bees

Posted by in category: cosmology

Observational astronomy shows that newly discovered young stellar objects (YSOs) in the immediate vicinity of the supermassive black hole Sagittarius A located in the center of our galaxy behave differently than expected. They describe similar orbits to already known young evolved stars and are arranged in a particular pattern around the supermassive black hole.

Researchers create nanocubes forming floating checkerboards via self-assembly

Posted by in categories: chemistry, engineering, nanotechnology

Researchers have engineered nanosized cubes that spontaneously form a two-dimensional checkerboard pattern when dropped on the surface of water. The work, published in Nature Communications (“Self-assembly of nanocrystal checkerboard patterns via non-specific interactions”), presents a simple approach to create complex nanostructures through a technique called self-assembly.

“It’s a cool way to get materials to build themselves,” said study co-senior author Andrea Tao, a professor in the Aiiso Yufeng Li Family Department of Chemical and Nano Engineering at the University of California San Diego. “You don’t have to go into a nanofabrication lab and do all these complex and precise manipulations.”

Each nanocube is composed of a silver crystal with a mixture of hydrophobic (oily) and hydrophilic (water-loving) molecules attached to the surface. When a suspension of these nanocubes is introduced to a water surface, they arrange themselves such that they touch at their corner edges. This arrangement creates an alternating pattern of solid cubes and empty spaces, resulting in a checkerboard pattern.
