Deep below the surface in coastal sediments, microorganisms use conductive particles as tiny natural "wires" to exchange electrons. This enables them to convert organic carbon into methane in a way not previously documented. The mechanism is described in a new study in Nature
Most people have experienced it: when you're moving, engaged, and focused, pain fades into the background, then flares when you're immobilized with nothing to do. That isn't imagination; it's biology. A comprehensive review published in Frontiers in Animal Science shows that
Amino acids are like Lego blocks—they can be linked together to form complex structures called proteins. Unlike Legos, however, there are only 20 different types of amino acids available to build a protein. Proteins depend on posttranslational modifications, or chemical changes
The word "nemotia" is a neologism, a newly coined term that in this case, describes the sense of overwhelmingness and disconnect accompanying the thought that nothing you do will ever make a difference. If this describes your current frame of mind, you might find some comfort
Researchers from several Parisian institutions have worked together to develop a non-destructive approach to study how unicellular organisms respond to stress, focusing on cell-to-cell differences. Working together, the researchers combined custom fluorescence microscopy with

Scientists are envisioning an antimatter delivery program that could ferry antiprotons from CERN to other labs around Europe.
A new QUT-led study has found both grazing mammals and plant-eating insects together play a major role in maintaining the health of Australia's endangered grassy woodlands. The three-year study, conducted in lowland grassy woodlands of New South Wales' Bega Valley, found that
The technology used to predict sand and dust storm (SDS) severity has for decades systematically overestimated when and where sediment is transported across Earth's surface, a new study shows. Existing models, which draw on satellite, surface, Light Detection and Ranging
An international research team has successfully synthesized oriented belt-shaped vanadium dioxide (VO2(B)) single crystals via a hydrothermal reduction method, using one-dimensional vanadium pentoxide (V2O5) nanofibers as the starting material. This work, published in the
Invasive species cost Canada billions of dollars each year. Now, a team led by UBC researchers has developed a new genomic test that can trace the Asian spongy moth—one of the biggest threats to North America's forests—back to its source, giving officials a better chance of
Social Security's trust funds are projected to run out by 2035, but that doesn't mean retirees will be left with nothing. New research from the Cornell SC Johnson College of Business reveals that most Americans misinterpret what happens when the funds reach zero, and the way

Self-driving laboratories (SDLs) powered by artificial intelligence (AI) are rapidly accelerating materials discovery, but can they also explain their results? Researchers from the Theory Department of the Fritz Haber Institute, in collaboration with BASF, and BasCat—UniCat
Toward the right side of the periodic table below oxygen, are the chalcogens, or "ore-forming" elements. The chalcogens that occur naturally, including sulfur, selenium and tellurium, are all somehow involved in biological processes. Molecules containing sulfur, like the
New research led by scientists at UC San Diego's Scripps Institution of Oceanography is shining a spotlight on one of the ocean's most overlooked habitats: seagrass. Led by Scripps Oceanography Ph.D. candidate Rilee Sanders, the study documented the first successful restoration
Droughts are becoming both more frequent and more intense in many parts of the world. Savannas, which cover nearly 20% of Earth's land surface and play a key role in carbon, water and energy cycles, can therefore be severely affected when an exceptionally dry period strikes.
Many people use drugs, including paracetamol, on a regular basis to treat headaches. But only part of each drug is taken into the bloodstream, while the rest is released into the wastewater through our urine when we go to the toilet.
