Phys.org / CO₂ emissions from cultivated peat soils may be lower than assumed
Organic soils cover less than 9% of Norway's land area, and about 65,000 hectares are currently used as agricultural land. Emissions from these areas are presently estimated at more than 2 million tons of CO₂ equivalents ...
Tech Xplore / AI-guided snakebot unlocks rolling move that doubles speed per unit power
Snake-like robots represent the future of rescue. Their slender bodies allow them to navigate narrow spaces, uneven terrain, and water surfaces, entering places that would be hazardous for humans. This could potentially save ...
Medical Xpress / Immune system uses a conveyor belt-like process to edit defective antibodies, new research finds
The immune system's B cells create antibodies that can mount a response against just about anything—either destroying a pathogen or instructing the rest of the immune system to go after the offender. But what happens when ...
Phys.org / In Arizona's desert, tiny ants turn into living hygienists, climbing inside bigger ants' mandibles and cleaning them
Ants are known for many things. They fight, bite and sometimes compete for every crumb. We can now possibly add cleaning services to that list, according to a study published in the journal Ecology and Evolution.
Medical Xpress / Mitochondria keep key immune cells battle-ready by sustaining electron flow, study reveals
Researchers at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) show that active mitochondria maintain dendritic cells, the immune system's sentinels, in a "ready-to-respond" state, linking cellular ...
Phys.org / Cracking a 16-year proton mystery as ultra-precise hydrogen measurements confirm a smaller-than-expected core
The simplicity of a hydrogen atom makes it an ideal model for studying atomic structure and interactions. Yet, despite the fact that its simplest form consists of only one proton and one electron, physicists have had a hard ...
Phys.org / 'Ghost tunnels' guide sound waves in one direction while staying invisible to others
Acoustic metamaterials are a fast-evolving family of materials which manipulate sound waves in ever more advanced ways. Now, a team led by Changqing Xu at Nanjing Normal University in China has engineered an acoustic metamaterial, ...
Medical Xpress / Chloride ions do more than help neurons fire—they may also help control how genes are expressed
Chloride ions, best known for helping cells maintain fluid balance and electrical stability, may also play a more direct role in regulating brain development than previously thought. In a new study, published in the journal ...
Phys.org / Graphene as a charge mirror: Why water droplets 'see' graphene—but don't show it
Research on graphene has made great strides in recent years. However, to fully harness its potential in applications such as desalination membranes, sensors, and energy storage and conversion, a deeper understanding of the ...
Phys.org / Ocean eddies are amplifying climate extremes in coastal seas, study finds
New research reveals a powerful yet overlooked driver of climate change: intensifying ocean eddies. These swirling currents—that break off from major currents—are redistributing heat and nutrients in the ocean and amplifying ...
Phys.org / Saltwater is closing in on coastal groundwater, putting billions and food supplies at risk
Coastal groundwater is a key source of drinking water in many regions of the world. However, it is threatened by overabstraction and the potential for salinization. Rising sea levels are further exacerbating the situation. ...
Phys.org / Webb redefines the dividing line between planets and stars
Planets, like those in our solar system, form in a bottom-up process where small bits of rock and ice clump together and grow larger over time. But the heftier the planet, the harder it is to explain its formation that way.
