Phys.org / Reversible spin splitting effect achieved in altermagnetic RuO₂ thin films
A research team affiliated with UNIST has made a advancement in controlling spin-based signals within a new magnetic material, paving the way for next-generation electronic devices. Their work demonstrates a method to reversibly ...
Phys.org / The sound of droplets striking water: How cowbirds control two sound sources in the syrinx to create 'liquid notes'
Cowbirds are special among songbirds for the "watery" timbre of their singing, which resembles the sound of falling droplets striking water, a quick burst followed by a fading ripple.
Phys.org / AI mimics human-like intuition to explore and analyze chemical reactions
Chemical reactions are the breaking and forming of chemical bonds, which are fundamental to the creation of new technologies. Inevitably, discovering and developing new chemical reactions is a time-intensive process of trial ...
Phys.org / An ecosystem never forgets: Extreme heat and drought responses linked to hydrological memory
The low-latitude highlands region of southwestern China experienced two major climate events in recent years: a severe drought in 2009–2010 and an extreme heat wave in 2019. Though both sprang from similar large-scale atmospheric ...
Phys.org / How soil and human antibiotic resistance are connected
A study led by researchers at the Department of Civil Engineering at The University of Hong Kong (HKU) has uncovered alarming evidence that soil worldwide is emerging as a significant reservoir and amplifier of high-risk ...
Phys.org / Structural findings reveal how distinct GPCR ligands create different levels of activation
G-protein coupled receptors (GPCRs) are proteins triggered by ligands (protein-binding chemicals) from outside cells to transmit signals inside the cell. These signals are transmitted primarily through the activation of G ...
Phys.org / Mixing incentives and penalties found key to cutting carbon emissions long term
A study from a team of researchers that includes faculty from the University of California San Diego and Princeton University shows how a mix of subsidies for clean energy and taxes on pollution can significantly reduce greenhouse ...
Phys.org / Some mammals can hit pause on a pregnancy—understanding how that happens could help us treat cancer
Seals give birth only when conditions are right. After mating, a female seal can delay implantation of the embryo in the uterine wall—pausing pregnancy until she senses that her fat reserves are aligned with the season. ...
Phys.org / Warming may make tropical cyclone 'seeds' riskier for Africa
An existing body of research indicates that climate change is making tropical cyclones wetter and more powerful. Now, a new study is indicating the same thing may be happening to the precursors of these storms: the wet weather ...
Phys.org / Capturing the moment a cell shuts the door on free radicals
For the first time, researchers have been able to show how a cell closes the door to free radicals—small oxygen molecules that are sometimes needed, but that can also damage our cells. The study is published in Nature Communications ...
Phys.org / Life's first molecule: Borate boosts its formation, finds study
The transition from simple chemistry to the complex biology of molecules that gave rise to life is a puzzle that scientists have been trying to solve for ages.
Phys.org / Scientists who use AI tools are publishing more papers than ever before
Science is entering a massive publishing boom, in large part due to artificial intelligence. New research published in the journal Science has revealed that scientists who use large language models (LLMs) like ChatGPT are ...
