Phys.org / All-optical modulation in silicon achieved via an electron avalanche process
Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics. These include photonic and quantum systems that could advance imaging, communication and information ...
Phys.org / Dual substitution induces room-temperature ferromagnetism and negative thermal expansion in BiFeO₃
Using a dual-cation substitution approach, researchers at Science Tokyo introduced ferromagnetism into bismuth ferrite, a well-known and promising multiferroic material for next-generation memory technologies. By replacing ...
Phys.org / Ear piercings marked one of the earliest Maya rites of passage, research shows
In a recent study, Ph.D. candidate Yasmine Flynn-Arajdal studied iconographic representations of children in the Classic (ca. 250–950 AD) and Post-classic (ca. 950–1539 AD) imagery, as well as in ethnohistoric and ethnographic ...
Phys.org / Tiny optical modulator could enable giant future quantum computers
Researchers have made a major advance in quantum computing with a new device that is nearly 100 times smaller than the diameter of a human hair.
Phys.org / Parker Solar Probe spies solar wind 'U-turn'
Images captured by NASA's Parker Solar Probe as the spacecraft made its record-breaking closest approach to the sun in December 2024 have now revealed new details about how solar magnetic fields responsible for space weather ...
Phys.org / Unlocking the sun's magnetic secrets: AI-powered mapping unlock intricate 3D details
Researchers at the University of Hawaiʻi Institute for Astronomy (IfA) are helping reshape how scientists study the sun. The UH-led team has developed a new artificial intelligence (AI) tool that can map the sun's magnetic ...
Phys.org / Researchers discover new protein-RNA interaction with potential to treat tissue scarring
A research team at Florida State University's Institute of Molecular Biophysics and Department of Chemistry and Biochemistry has discovered how a protein found in the human body interacts with RNA in a way that could lead ...
Phys.org / Break the mold: Who defines the 'real' chemist?
The perception of a chemist varies. Some might imagine the "mad scientist" from old cartoons—a white-haired older man working with beakers in his lab—but as that cliche fades, the reality of what constitutes a chemist's ...
Phys.org / Tracing a path through photosynthesis to food security
The energy that plants capture from sunlight through photosynthesis provides the source of nearly all of humanity's food. Yet the process of photosynthesis has inefficiencies that limit crop productivity, especially in a ...
Phys.org / Fungal allies arm plant roots against disease by rewriting the rules of infection
Scientists have discovered that beneficial root-dwelling fungi boost plant resilience to disease by remodeling the plant cell membrane at pathogen infection sites—offering critical new insights into how plants coordinate ...
Phys.org / How extreme weather events affect agricultural trade between US states
The U.S. is largely self-sufficient in agricultural food production, supported by a well-developed storage and interstate trade system. However, extreme weather events put increasing pressure on agriculture, potentially impacting ...
Phys.org / Chip-scale magnetometer uses light for high-precision magnetic sensing
Researchers have developed a precision magnetometer based on a special material that changes optical properties in response to a magnetic field. The device, which is integrated onto a chip, could benefit space missions, navigation ...
