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 ...
Phys.org / Checklist offers guide to verifying authenticity of nature and carbon credits
Global leaders have committed to halting and reversing the ongoing degradation of nature within the next few decades. But with tight public budgets, governments around the world are looking toward nature markets as one way ...
Phys.org / Cryo-EM structures reveal conformational dynamics behind AP-4 membrane trafficking
Adaptor protein (AP) complexes play central roles in intracellular vesicular trafficking by coupling cargo selection to vesicle formation. AP-4, an important member of the AP family, plays a key role in this process. AP-4 ...
Phys.org / Stealth and manipulation: Strategies of bacterial plasmids investigated
The problem of antibiotic-resistant bacteria has many health experts worried. As disease-causing bacteria adapt to some of our ways to reduce them, especially with antibiotics, it presents an arms race which we appear to ...
