Phys.org / Study reveals hidden climate impact of digital industries
Digital technologies are widely viewed as drivers of efficiency, growth, and innovation. However, their contribution to climate change is significantly greater than previously understood. A new study published in the journal ...
Phys.org / Electrochemical signals can reshape bacterial protein patterns, boosting electron transfer
Sometimes, transporting electrons from one cell to another is a team effort. In electroactive bacteria, that team is a group of proteins that shepherds electrons forward, passing them along like a relay baton, so they can ...
Phys.org / Ultrafast X-rays reveal physical principles behind lipoprotein motion within egg yolk plasma
Egg yolk may appear runny and uniform, but on the nanoscale, it is one of the most crowded biological fluids in nature. Packed with proteins and fats, it serves as a dense storage reservoir for a developing embryo. Yet the ...
Phys.org / Scientists deliver new molecule for getting DNA into cells
Researchers from Tokyo Metropolitan University have created a new molecule which carries DNA into biological cells, to treat or vaccinate against illnesses. Many existing options rely on molecules with a strong positive charge, ...
Phys.org / Earth's mantle may have been cooler than thought before Pangea's breakup
When the supercontinent Pangea began to fragment around 200 million years ago during the Early Jurassic, it reshaped the face of the planet. Vast new oceans opened, continents drifted apart and the familiar geography of today ...
Phys.org / Phosphoric acid dimers reveal nature's proton highway
Whether in our bodies or in fuel cells, phosphoric acid plays an important role in many chemical processes because it is exceptionally good at transporting charges. Researchers from the Department of Molecular Physics at ...
Phys.org / Global greening: Study shows Earth's green wave is shifting northeast
A team of scientists led by the German Center for Integrative Biodiversity Research (iDiv), the Helmholtz Center for Environmental Research (UFZ), and Leipzig University has developed a new method to track Earth's greenness—a ...
Phys.org / Researchers copy viral strategies to get mRNA medicines into cells in one piece
Drugs made of mRNA have the potential to transform medicine—if only they could get into cells in one piece. Now, University of Connecticut researchers have shown that packaging mRNA like a virus could smuggle it into cells ...
Phys.org / Scientists isolate climatic fingerprints of wildfires and volcanic eruptions
Volcanoes and wildfires can inject millions of tons of gases and aerosol particles into the air, affecting temperatures on a global scale. But picking out the specific impact of individual events against a background of many ...
Phys.org / How cells manage nitric oxide: Research uncovers dynamic 'gate' that tames powerful signaling molecule
Cornell researchers have uncovered a built-in molecular "gate" that controls the production of the molecule nitric oxide, a crucial signaling molecule throughout biology that in humans helps regulate blood pressure, brain ...
Phys.org / Between flood and drought: The metric that could better explain what happens to water in the age of climate change
A key question in any discussion about climate is "How much rain fell?" But perhaps there is an even more important one. Like any household budget, the global water economy is based on "income," that is, water entering the ...
Phys.org / From algae to biofuel: Study opens doors to cheaper, cleaner fuel sources
A researcher's keen eye and spirit of curiosity led to the discovery of a new method for cell engineering—a finding that opens doors to more sustainable sources for everything from fuel to vitamin supplements.
