Earth and the course of life on Earth have been shaped by impacts. Scientists have uncovered links between massive impacts and changes in climate that altered the planet forever. But the further scientists look into the past ...

Researchers at Cincinnati Children's, working with collaborators at University College London and Oak Ridge National Laboratory, have identified a practical, data-centered strategy to reduce bias in artificial intelligence ...

Hydrogen is a clean-burning gas that could help to tackle climate change by reducing our dependence on fossil fuels. But storing and transporting hydrogen is expensive and technically challenging, typically requiring high-pressure ...

The human immune system is finely tuned to detect and destroy viral threats. But this same defense system can misfire. When fragments of the body's own damaged DNA are mistaken for viral invaders, the result is a powerful, ...

NASA and other space agencies are intent on sending astronauts back to the moon, and this time, to stay! A vital part of these plans for reducing costs and dependency on Earth is the process of In-Situ Resource Utilization ...

Researchers at Delft University of Technology (TU Delft) have designed a portable game console powered by solar panels and a cranking device. They embedded the crank into the gameplay experience, allowing users to—for example—fire ...

Giant migrating contractions (GMCs) are powerful waves of colonic movement that propel intestinal contents toward the anus and are essential for defecation. Yet despite their physiological importance, the mechanisms that ...

Dramatic droughts linked to the decline of the Classic Maya civilization approximately 800 to 1000 CE may not have required any external trigger, according to a new climate modeling study. Instead, they could have emerged ...

Large language models (LLMs) can teach other algorithms unwanted traits, which can persist even when training data has been scrubbed of the original trait, according to new research published in Nature. In one example, a ...

Researchers from North Carolina State University have successfully synthesized bacteriochlorophyll a, which is a photosynthetic pigment found in bacteria that absorbs infrared light. The work represents the first chemical ...

Archaeologists working at the ancient settlement of Stăuceni-"Holm" in northeastern Romania have uncovered a mega-structure measuring 350 square meters dating back about 6,000 years. This is one of the few examples of a massive ...

If you can't get no satisfaction, then maybe it's because happiness does not only stem from pleasure or a meaningful existence. Instead, a new Simon Fraser University study suggests that freedom is the key to happiness.
