Apple Bursts Onto the AI Stage with Apple Intelligence, ChatGPT, and Multimodal Siri

Posted by in categories: finance, robotics/AI

Apple also announced a ton of other home-grown AI innovations during Monday’s show. This includes AI-generated emojis called Genmoji, a feature that prioritizes important messages, another that summarizes group chats, and Safari will also create AI summaries of webpages.

The financials of Apple’s deal with OpenAI were not disclosed on Monday, and that element remains unclear. While Google has paid Apple billions of dollars for default privileges on Apple products, OpenAI may require an investment to provide computing of this magnitude. Processing AI requests for billions of people is anything but cheap. If Apple pays OpenAI for this, Microsoft may ultimately benefit from this deal.

New study reveals brain’s fractal-like structure near phase transition, a finding that may be universal across species

Posted by in categories: nanotechnology, neuroscience, physics

While researchers have long studied brain dynamics using imaging (fMRI) and electroencephalograms (EEG), advances in neuroscience have only recently provided massive datasets for the brain’s cellular structure. These data opened possibilities for Kovács and his team to apply statistical physics techniques to measure the physical structure of neurons.

For the new study, Kovács and Ansell analyzed publicly available data of 3D brain reconstructions from humans, fruit flies and mice. By examining the brain at nanoscale resolution, the researchers found the samples showcased hallmarks of physical properties associated with criticality.

One such property is the well-known, fractal-like structure of neurons. This nontrivial fractal-dimension is an example of a set of observables, called “critical exponents,” that emerge when a system is close to a phase transition.

New insights on the role of nucleon exchange in nuclear fusion

Posted by in categories: computing, nuclear energy, physics

A recent study has explored the influence on low-energy fusion processes of isospin composition. This is a key nuclear property that differentiates protons from neutrons. The researchers used and theoretical modeling to investigate the fusion of different nuclei with varying isospin configurations. The results show that the isospin composition of the nuclei in a fusion reaction plays a crucial role in understanding the reaction. The paper is published in the journal Physical Review C.

In this study, researchers at Fisk University and Vanderbilt University used high-performance computational and theoretical modeling techniques to conduct a detailed many-body method study of how the dynamics of isospin influence nuclear fusion at low energies across a series of isotopes. The study also examined how the shape of the nuclei involved affect these dynamics. In systems where the nuclei are not symmetrical, the dynamics of isospin become particularly important, often leading to a lowered fusion barrier, especially in systems rich in neutrons. This phenomenon can be explored using facilities that specialize in the generation of beams composed of exotic, unstable nuclei.

The findings provide critical knowledge regarding the fundamental nuclear processes governing these reactions, which have broad implications for fields such as , astrophysics, and, perhaps someday, fusion-based energy.

How does light interact with matter at extreme intensities, near the Schwinger limit?

Posted by in category: physics

The experimental generation of increasingly intense light beams could help to unveil new physical regimes occurring in the presence of very strong electromagnetic fields. While some progress has been made towards this goal, physicists are yet to develop a reliable strategy to achieve extreme light intensities.

The discovery of new turbulence transition in fusion plasmas

Posted by in category: nuclear energy

Fusion energy is released when two light nuclei combine to form a single heavier one (nuclear fusion reaction). Fusion energy-based power generation (fusion power plant) uses the energy generated when deuterium and tritium combine to form helium.

Lone star state: Tracking a low-mass star as it speeds across the Milky Way

Posted by in category: space

It may seem like the sun is stationary while the planets in its orbit are moving, but the sun is actually orbiting around the Milky Way galaxy at an impressive rate of about 220 kilometers per second—almost half a million miles per hour. As fast as that may seem, when a faint red star was discovered crossing the sky at a noticeably quick pace, scientists took notice.
