The structure-performance relationship of low-dielectric systems can be explored through P-V-L theory, first-principles calculations, and lattice vibration spectroscopy. The initial application of this research can be demonstrated through the design and testing of microstrip antennas. Credit: Journal of Advanced Ceramics, Tsinghua University Press Microwave dielectric ceramics are the cornerstone of wireless communication devices, widely utilized … Read more

This image shows a plant protein known as KIN10 (yellow) that acts as a sensor and a switch to turn oil production off or on depending on whether it interacts with another protein (green). Credit: Brookhaven National Laboratory Proteins are molecular machines, with flexible pieces and moving parts. Understanding how these parts move helps scientists … Read more

Credit: University of Bristol Researchers at the University of Bristol have made an important breakthrough in scaling quantum technology by integrating the world’s tiniest quantum light detector onto a silicon chip. The paper, … Read more

Klara Wolf (left) samples Actic phytoplankton in Kongsfjorden, Ny Ålesund, Svalbard. Credit: Alfred-Wegener-Institut / Paolo Verzone The basis of the marine food web in the Arctic, the phytoplankton, responds to heat waves much differently than to constantly elevated temperatures. This has been found by the first targeted experiments on the topic, which were recently conducted … Read more

Depicting perturbative algebraic QFT (qAQFT) as bringing the earlier strands of axiomatic QFT and causal perturbation theory together. Credit: The European Physical Journal H (2024). DOI: 10.1140/epjh/s13129-024-00075-6 Perturbative expansion is a valuable mathematical technique which is widely used to break down descriptions of complex quantum systems into simpler, more manageable parts. Perhaps most importantly, it … Read more

A person’s hands cup a sample of pelletized agricultural fertlizer and a piece of the phosphate rock from which it is created. Credit: Robert Hill, Duke University An international team of scientists has uncovered toxic metals in mineral phosphate fertilizers worldwide by using a new tool to identify the spread and impact of such contaminants … Read more

DOI: 10.1007/s11783-024-1825-2 Environmental data science and machine learning (ML) are increasingly vital for addressing ecological challenges. However, these technologies can inadvertently perpetuate biases present in their training data, leading to socioecological inequities. The field faces issues such as data integrity, algorithmic bias, and model overfitting, which necessitate … Read more

Coral around the world is in the grip of a bleaching event. Jakkapat Yodnil calls out to visitors at a diving expo in Bangkok, eager to share details of his shop’s expeditions to the azure waters around the Thai island of Koh Tao. But behind the friendly sales pitch, the 25-year-old fears that bleaching affecting … Read more

Relationship between indirect and direct reproductive costs. Credit: Science (2024). DOI: 10.1126/science.adk6772 A new study published in Science and led by Monash University biologists reveals that the energy cost of reproduction is far greater than previously believed. The research, led by Dr. Samuel C Ginther from the School of Biological Sciences challenges long-held assumptions about … Read more
