Computer scientists at the University of California San Diego have developed a method for generating highly realistic computer-generated images of fluid dynamics in elements such as smoke.

This research, conducted by the UC San Diego Center for Visual Computing, was presented at the SIGGRAPH Asia 2024 conference, where it received a Best Paper Honorable Mention for its contributions to computer graphics and physics-based simulation. The paper is published in ACM Transactions on Graphics.

To demonstrate the power of their approach, the team compared an iconic photograph from the 1980 eruption of Mount Saint Helens volcano in Washington State to a computer-generated rendering of a volcanic smoke plume created using their new method. The resulting simulation captures the intricate, multi-scale billowing of the smoke plume, including its twisting, curling motion and delicate turbulence, which are hallmarks of realistic fluid behavior.

USTC researchers created a groundbreaking on-chip photonic simulator, leveraging thin-film lithium niobate chips to simplify quantum simulations of complex structures, achieving high-dimensional synthetic dimensions with reduced frequency demands.

A research team led by Prof. Chuanfeng Li from the University of Science and Technology of China (USTC) has made a significant breakthrough in quantum photonics. The team successfully developed an on-chip photonic simulator capable of modeling arbitrary-range coupled frequency lattices with gauge potential. This achievement was detailed in a recent publication in Physical Review Letters.

<em>Physical Review Letters (PRL)</em> is a prestigious peer-reviewed scientific journal published by the American Physical Society. Launched in 1958, it is renowned for its swift publication of short reports on significant fundamental research in all fields of physics. PRL serves as a venue for researchers to quickly share groundbreaking and innovative findings that can potentially shift or enhance understanding in areas such as particle physics, quantum mechanics, relativity, and condensed matter physics. The journal is highly regarded in the scientific community for its rigorous peer review process and its focus on high-impact papers that often provide foundational insights within the field of physics.

Forget conventional electronics, DNA tech stores data, offers computing functions.

Called “primordial DNA store and compute engine,” the technology could store data securely for thousands of years in commercially available spaces without degrading the information-storing DNA, suggests testing.

In conventional computing technologies, the ways data are stored and processed are compatible with each other, according to researchers. However, in reality, data storage and data processing are done in separate parts of the computer, and modern computers are a network of complex technologies.

The new technology is made possible by using recent developments, which have enabled the creation of soft polymer materials that have unique morphologies.

A recent study published in PLOS Computational Biology found that people with stronger autistic traits, particularly those with a preference for predictability, tend to exhibit unique curiosity-driven behaviors. These individuals showed persistence in tasks requiring sustained attention, often leading to superior learning outcomes.

Autism spectrum disorder is a developmental condition that affects how individuals perceive and interact with the world. It is characterized by differences in communication, social interaction, and behavior patterns. Rather than being a singular condition, autism exists on a spectrum, meaning that individuals experience varying levels of intensity and expression of traits. While some may require significant support in daily life, others might navigate independently with unique strengths and challenges.

Autistic traits are characteristics commonly associated with autism but may also be present in varying degrees within the general population. These traits can include a preference for routines, heightened sensitivity to sensory input, and intense focus on specific topics of interest. While these traits can sometimes pose challenges, they also contribute to unique ways of thinking and problem-solving.

New research demonstrates a brand-new architecture for scaling up superconducting quantum devices. Researchers at the UChicago Pritzker School of Molecular Engineering (UChicago PME) have realized a new design for a superconducting quantum processor, aiming at a potential architecture for the large-scale, durable devices the quantum revolution demands.

Unlike the typical quantum chip design that lays the information-processing qubits onto a 2-D grid, the team from the Cleland Lab has designed a modular quantum processor comprising a reconfigurable router as a central hub. This enables any two qubits to connect and entangle, where in the older system, qubits can only talk to the qubits physically nearest to them.

“A quantum computer won’t necessarily compete with a classical computer in things like memory size or CPU size,” said UChicago PME Prof. Andrew Cleland. “Instead, they take advantage of a fundamentally different scaling: Doubling a classical computer’s computational power requires twice as big a CPU, or twice the clock speed. Doubling a quantum computer only requires one additional qubit.”
