Phys.org / New data show reduced overall PFAS exposures in subarctic ocean
Beginning in the early 2000s, some of the most common and well-studied PFAS were phased out through a combination of industry shifts and international regulations. A new study from Harvard has found that since that phaseout, ...
Phys.org / Lit bots beware: AI creative writing faces reader skepticism, study shows
When it comes to creative writing, score one for the humans over the machines. For now, anyway. New research finds that people evaluate creative writing less favorably when they learn it was generated in whole or part by ...
Phys.org / Early warning for wine spoilage glows in the dark
Researchers built a living biosensor made of bacteria that lights up when it detects acetic acid, the main chemical signal that wine is starting to spoil. It works in real time, even in high-alcohol conditions, so wineries ...
Phys.org / New DNA 'page numbers' method enables accurate assembly of long genetic sequences
The power of artificial intelligence (AI) and advanced computing has made it possible to design genetic sequences encoding for diverse biological applications, such as proteins that form the building blocks of materials stronger ...
Phys.org / Scientists reveal gold precipitation mechanism at pyrite-water interface
Gold is generally associated with pyrite (iron disulfide, FeS2), and pyrite-induced gold precipitation is critical to the formation of high-grade gold deposits. However, the role of pyrite in precipitating gold from fluids ...
Phys.org / Q&A: Even small amounts of online math practice can improve skills
An analysis of data from 200,000 students using a computer-assisted math program supports an optimistic view of skill-focused, mastery-based learning, even with limited use.
Phys.org / Harvestmen arachnids apparently use fluorescent patterns for species recognition
A research team from Munich has identified a previously unknown communication mechanism in harvestmen. Five closely related species show species-specific, strongly fluorescent structures on their backs that become especially ...
Phys.org / Perceiving AI as a 'job killer' negatively influences attitudes towards democracy, study suggests
Artificial intelligence is rapidly changing our society and economy. A new study shows that the majority of people believe that artificial intelligence is displacing more human labor than it is creating new opportunities. ...
Phys.org / AI generates short DNA sequences that show promise for gene therapies
Scientists at the Broad Institute and Mass General Brigham have built a generative AI model that creates short DNA segments that can control gene activity in specific cells. These sequences, called cis-regulatory elements ...
Phys.org / Tapping the engines of cellular electrochemistry and forces of evolution
Researchers at Washington University in St. Louis have a unique resource in the form of the Center for Biomolecular Condensates at the McKelvey School of Engineering, which draws scientists from around the world to study ...
Phys.org / AI tool Helixer identifies genes in newly sequenced organisms
Researchers at Forschungszentrum Jülich and Heinrich Heine University Düsseldorf have developed a tool that could significantly transform genome research: Helixer identifies genes directly from DNA sequences—without laboratory ...
Phys.org / New evidence reveals how Greenland's seaweed locks away carbon in the deep ocean
An interdisciplinary study confirms, for the first time, the oceanographic pathways that transport floating macroalgae from the coastal waters of Southwest Greenland to deep-sea carbon reservoirs, potentially playing a previously ...
