New research from Adelaide University is questioning the widespread use of the term "resilience" in Australian agriculture, arguing that its overuse can place unfair pressure on individual farmers and obscure the need for systemic support. Published in the Journal of Rural
In an era of rising grocery costs, eggs remain one of the most accessible and complete protein sources for families. New research from the University of Hawai'i at Mānoa's College of Tropical Agriculture and Human Resilience (CTAHR) is investigating how chickens age to help
Inspired by the simple mechanism of a seesaw—when one side goes up, the other side goes down—researchers asked an intriguing question: Could a single molecule switch between two different roles like a seesaw? This idea led to the creation of a new type of artificial protein
Antarctica plays a crucial role in Earth's climate system by reflecting solar radiation back into space. The large white ice surfaces and clouds play a decisive role in this process. However, how clouds actually form in Antarctica, how they interact with the atmosphere and what

Hundreds of thousands of marine animals are killed every year after becoming accidentally caught in commercial fishing nets. Sharks, skates and rays are at particular risk, alongside turtles, seals, whales and dolphins, many of which are endangered.
Recurrent droughts, conflict, and changing land use have placed significant strain on pastoral populations in the dryland regions of Africa, resulting in numerous crises that require humanitarian intervention. Pastoralism is both an economic activity and a cultural identity
Space junk returning to Earth is introducing metal pollution to the pristine upper atmosphere as it burns up on re-entry, a new study has found.
Ribosomes, the cell's protein-making factories, consume large amounts of energy as they build the proteins that keep cells alive and functioning. When cells experience stress—such as lack of nutrients or sudden drops in temperature—they quickly switch into survival mode. New

When we hear certain sounds, our brains often pair them with specific shapes. For example, most people will associate a sharp-sounding word with a jagged, pointed shape, while a soft, rolling word is linked to something smooth and curved. This fascinating phenomenon is known as
As countries strive to achieve the United Nations' Sustainable Development Goals (SDGs) by 2030, a new international study published in Nature Communications brings together 19 researchers in 13 institutions—including Jianguo "Jack" Liu, Rachel Carson Chair in Sustainability
Since the third Gaia data release in 2022, wide binary stars with separation greater than several thousand astronomical units have been intensely investigated across the world, to probe the nature of gravity in the low acceleration regime, weaker than about 1 nanometer per

In crowds, most people are strangers to you, and everyone else for that matter. However, until now, the effect of stranger-to-stranger interactions on the choices people make in crowds has not been properly examined. Ziqi Wang and Federico Toschi from the TU/e Department of
For the first time in Brazil, researchers have identified a field of tektites. These are natural glasses formed by the high-energy impact of extraterrestrial bodies against Earth's surface. These structures, named geraisites in honor of the Brazilian state of Minas Gerais,
A small but mighty piece of lab equipment, about the size of a cellphone, has arrived at the International Space Station after launching with NASA's SpaceX Crew-12 mission. NASA aims to use the off-the-shelf device, called a microplate reader, to conduct vital biological
Ribonucleotide reductases (RNR) are indispensable enzymes that convert ribonucleotides to deoxyribonucleotides (dNTPs), the precursors to make up DNA. Because DNA synthesis is fundamental to cell survival, RNR activity must be tightly controlled. In bacteria, this control is
With a new mathematical model, a team of biophysicists has revealed fresh insights into how biological tissues are shaped by the active motion of structural imperfections known as "topological defects." Published in Physical Review Letters, the results build on our latest
When 200 natural accessions of the model plant Arabidopsis thaliana grown in a nitrate-enriched medium were compared, one observation stood out: some accessions formed significantly longer lateral roots than others. Genetic analysis revealed a difference in a gene called MEKK14.
Human beings are social animals; they need places to relax, connect with others, and feel a sense of belonging beyond the demands of home and work. Traditionally, these "third places" are thought to be limited to cafes, clubs, gardens, and other neighborhood community spots.
Green hydrogen production technology, which utilizes renewable energy to produce eco-friendly hydrogen without carbon emissions, is gaining attention as a core technology for addressing global warming. Green hydrogen is produced through electrolysis, a process that separates
