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 / 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 / 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 / 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 / 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 / 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 ...
Phys.org / Controlling exciton flow in moiré superlattices: New method leverages correlated electrons
Excitons are pairs of bound negatively charged electrons and positively charged holes that form in semiconductors, enabling the transport of energy in electronic devices. These pairs of charge carriers also emerge in transition ...
Phys.org / SN 2022ngb is a faint and slow-evolving Type IIb supernova, observations reveal
An international team of astronomers has conducted optical and near-infrared observations of a supernova designated SN 2022ngb. As a result, it was found that SN 2022ngb is a faint and slow-evolving Type IIb supernova with ...
Phys.org / Muddy eruption at Yellowstone's Black Diamond Pool captured on video
"Kablooey!" That's the word U.S. Geological Survey volcanic experts used to describe a muddy eruption at Black Diamond Pool in Yellowstone National Park on Saturday morning.
