From branches to loops: The physics of transport networks in nature

An international team of researchers described how loops, crucial for the stability of such networks, occur in transport networks found in nature. The researchers observed that when one branch of the network reaches the system’s boundary, the interactions between the branches change drastically. Previously repelling branches begin to attract each other, leading to the sudden […]

Nonlinear optical metasurface achieves electrically tunable third-harmonic generation

A recent study has unveiled a transformative nonlinear optical metasurface technology. This new technology, characterized by structures smaller than the wavelength of light, paves the way for significant advancements in next-generation communication technologies, including quantum light sources and medical diagnostic devices.

Study suggests moon may have been captured from space rather than formed from collision particles

Over six missions to the moon, from 1969 to 1972, Apollo astronauts collected more than 800 pounds of lunar rock and soil. Chemical and isotopic analysis of that material showed that it was similar to the rock and soil on Earth: calcium-rich, basaltic and dating to about 60 million years after the solar system formed.

Study uncovers first evidence of a volcanic spatter cone on Mars

While working under Erika Rader, an assistant professor in the Department of Earth and Spatial Sciences at University of Idaho, a postdoctoral researcher identified a volcanic vent on Mars as a potential spatter cone and compared it to a spatter cone formed during the 2021 eruption of Fagradalsfjall in Iceland.
