Phys.org / Simulations show six valves provide ideal setup for rapidly dispersing cooling gas
When the plasma inside a fusion system starts to misbehave, it needs to be quickly cooled to prevent damage to the device. Researchers at Commonwealth Fusion Systems believe the best bet is a massive gas injection: essentially, ...
Phys.org / Adding silicon to soil can help tomato plants fight South American tomato pinworm
A team of entomologists and botanists at the International Center of Insect Physiology and Ecology in Nairobi and the University of Pretoria has found that adding silicon to soil can help tomato plants fight off the destructive ...
Phys.org / Overlooked diversity: New research suggests plants, fungi and even viruses use venom
A new study reveals plants, fungi, bacteria, protists, and even some viruses deploy venom-like mechanisms, similar to that of venomous snakes, scorpions and spiders, according to researchers at Loma Linda University School ...
Phys.org / Tracking net-zero carbon debt: Who is responsible for overshoot of the 1.5°C climate limit?
What is a fair way forward after the 1.5°C warming limit of the Paris Agreement has been breached? In a new study, IIASA researchers explore the concept of "net-zero carbon debt"—a measure for assessing who bears greater ...
Phys.org / Language ambiguity: How children and adults interpret contextual pronouns differently
"Did you see that?" It is a simple phrase we hear every day, but how do we know what "that" refers to? A new study from Kyushu University, published in PLOS One, reveals that children and adults use different strategies to ...
Phys.org / New study uncovers key pathways in hydronium and hydroxide ion neutralization
A new study provides fresh insight into traditional acid-base chemistry by revealing that the mutual neutralization of isolated hydronium (H3O⁺) and hydroxide (OH⁻) ions is driven by electron transfer rather than the ...
Phys.org / Who is calling? Bats outsmart deception by solving sensory conflicts
Would you answer someone's cry for help if that someone was sitting unharmed in front of you? Most probably would not, and bats have similar reservations, according to a new study published in Current Biology in which researchers ...
Phys.org / Dynamic density functional theory offers new approach to understanding protein–membrane interactions
Proteins interacting with cell membranes play a vital role in countless biological processes, from how cells communicate to how they respond to external signals like hormones or medications. Understanding these interactions ...
Phys.org / C. diff uses toxic compound to fuel growth advantage, researchers discover
The pathogen C. diff—the most common cause of health care-associated infectious diarrhea—can use a compound that kills the human gut's resident microbes to survive and grow, giving it a competitive advantage in the infected ...
Phys.org / Scientists uncover how enzymes evolved to function at low temperatures
Life has evolved over billions of years, adapting to the changing environment. Similarly, enzymes—proteins that speed up biochemical reactions (catalysis) in cells—have adapted to the habitats of their host organisms. ...
Phys.org / TiO₂ nanoparticles offer simultaneous arsenic and uranium remediation from groundwater
A research team led by Prof. Luan Fubo from the Research Center for Eco-Environmental Sciences of the Chinese Academy of Sciences, has uncovered a novel mechanism involving a ternary surface complex on titanium dioxide (TiO₂) ...
Phys.org / Superoxide's role in enzyme-driven drug synthesis uncovered
Enzymes, the core catalysts in life, drive critical biological processes ranging from metabolic regulation to energy conversion. Evolved over billions of years, these versatile molecular machines not only serve as foundational ...
