New carbon-negative material could make concrete and cement more sustainable

Researchers injected CO2 gas into seawater while applying an electrical current. The process transformed dissolved ions, minerals in seawater into clusters of solid particles. The clusters hold over half their weight in CO2 to become a carbon sink. Material could replace sand in concrete and be used in other construction materials while trapping CO2.

Quantum heat dynamics toggled by magnetic fields

The ability to conduct heat is one of the most fundamental properties of matter, crucial for engineering applications. Scientists know well how conventional materials, such as metals and insulators, conduct heat. However, things are not as straightforward under extreme conditions such as temperatures close to absolute zero combined with strong magnetic fields, where strange quantum

Plant patch can detect stress signals in real time

Environmental conditions can cause damaging stress to plants, posing challenges for home gardeners and farmers. Therefore, early detection — before leaves visibly discolor, wilt or wither — is crucial. Now, researchers have created a wearable patch for plants that quickly senses stress and relays the information to a grower. The electrochemical sensor attaches directly to

Breakthrough in materials science: AI reveals secrets of dendritic growth in thin films

Dendritic structures that emerge during the growth of thin films are a major obstacle in large-area fabrication, a key step towards commercialization. However, current methods of studying dendrites involve crude visual inspection and subjective analysis. Moreover, growth optimization methods for controlling dendrite formation require extensive trial and error. Now, researchers have developed a new AI

EPA regulations cut power sector emissions but miss opportunities for deeper reductions

Regulations finalized by the Environmental Protection Agency in 2024 could cut emissions from the power sector by 51% over 2022 levels, compared to only 26% without the rules, according to a new analysis. The study helps identify the likely effects of current regulations, highlights the impact of potential repeal on U.S. emissions, and quantifies the
