Atomic nuclei are made of nucleons (like protons and neutrons), which themselves are made of quarks. When crushed at high densities, nuclei dissolve into a liquid of nucleons and, at even higher densities, the nucleons themselves dissolve into a quark liquid.

In a new study, published in the journal Physical Review B, researchers addressed the question of whether the liquids of nucleons and quarks are fundamentally different.

Their theoretical calculations suggest that these liquids are different. Both types of liquids produce vortices when they rotate, but in quark liquids, the vortices carry a “color-magnetic field,” similar to an ordinary magnetic field. There is no such effect in nucleon liquids. Thus, these vortices sharply distinguish quark liquids from nuclear liquids.

Alter 3 has just been unveiled by the University of Tokyo and its powered by GPT-4, capable of human-like activities and interpreting verbal instructions. Researchers at the Technical University of Munich developed a self-aware robot with proprioception, enhancing its movement and interaction capabilities. The University of Southern California introduced RoboCLIP, an algorithm that trains robots to perform tasks in new environments with minimal instruction. Intel Labs and partners created advanced motor control for robots using hierarchical generative models, significantly improving their ability to perform complex tasks.\

RENGE is a computational method that infers gene regulatory networks using time-series single-cell CRISPR data as input.

Polarization is one of the fundamental characteristics of electromagnetic waves. It can convey valuable vector information in sensitive measurements and signal transmission, which is a promising technology for various fields such as environmental monitoring, biomedical sciences, and marine exploration. Particularly in the terahertz frequency range, traditional device design methods and structures can only achieve limited performance. Designing efficient modulator devices for high-bandwidth terahertz waves presents a significant challenge.

Researchers led by Prof. Liang Wu at Tianjin University (TJU), China, have been conducting experiments in the field of all-dielectric metamaterials, specifically focusing on utilizing these materials and their structural design to achieve effective broadband polarization conversion in the terahertz frequency range.

They propose a cross-shaped microstructure metamaterial for achieving cross-polarization conversion and linear-to-circular polarization conversion in the terahertz frequency range. The study, titled “An all-silicon design of a high-efficiency broadband transmissive terahertz polarization convertor,” was published in Frontiers of Optoelectronics.

During the most recent excavations, archaeologists stumbled on a system of secret underground passageways. They found six intersecting tunnels that functioned as a hidden transportation network.

A photo shows a partial map of the passageways. Other photos show a tunnel entrance and a view inside the well-preserved arched tunnels.

Archaeologists said the tunnels were between about 5 feet and about 20 feet down. Inside, the tunnels were between 3 feet and 6 feet tall and roughly 4 feet wide. Several tunnels passed under the city’s defensive walls and opened to the outside.
