Dec 12, 2024 (Nanowerk News) A team of researchers led by Carnegie Science’s Will Ludington, Karina Gutiérrez-García, and Kevin Aumiller identified genes that enable a beneficial bacterial species to colonize specific regions of the gastrointestinal tract. Their work, published in Science ("A conserved bacterial genetic basis for commensal-host specificity"), could...
Precise control of liquid metal flow enables new flexible electronics manufacturing method
Dec 11, 2024 (Nanowerk Spotlight) Creating electronic circuits that can bend and flex while maintaining reliable electrical connections presents significant engineering challenges. Traditional electronics rely on solid metals like copper and gold, which provide excellent conductivity but can fail when subjected to repeated bending or stretching. This limitation affects applications...
Discovery of new growth-directed graphene stacking domains may precede new era for quantum applications
Dec 10, 2024 (Nanowerk News) Graphene, a single layer of carbon atoms arranged in a two-dimensional honeycomb lattice, is known for its exceptional properties: incredible strength (about 200 times stronger than steel), light weight, flexibility, and excellent conduction of electricity and heat. These properties have made graphene increasingly important in...
Silver nanocubes enable light generation in nanolaser
Dec 10, 2024 (Nanowerk News) Kaunas University of Technology (KTU), Lithuania researchers and scientists from Japan have developed a unique nanolaser. Although the dimensions of this laser are so small that its structure can only be seen through a powerful microscope, its potential is vast. With applications in early medical...
A new discovery about the source of the vast energy in cosmic rays
Dec 11, 2024 (Nanowerk News) Ultra-high energy cosmic rays, which emerge in extreme astrophysical environments—like the roiling environments near black holes and neutron stars—have far more energy than the energetic particles that emerge from our sun. In fact, the particles that make up these streams of energy have around 10...
Nanopore direct RNA sequencing identifies cancer ‘fingerprint’
Dec 10, 2024 (Nanowerk News) Different types of cancer have unique molecular ‘fingerprints’ which are detectable in early stages of the disease and can be picked up with near-perfect accuracy by small, portable scanners in just a few hours, according to a study published today in the journal Molecular Cell...
A coating for enhanced thermal imaging through hot windows
Dec 10, 2024 (Nanowerk News) A team of Rice University scientists has solved a long-standing problem in thermal imaging, making it possible to capture clear images of objects through hot windows. Imaging applications in a range of fields ⎯ e.g. security, surveillance, industrial research and diagnostics ⎯ could benefit from...
New computational framework discovers experimental designs in microscopy 10,000 faster
Dec 10, 2024 (Nanowerk News) For human researchers, it takes many years of work to discover new super-resolution microscopy techniques. The number of possible optical configurations of a microscope — for example, where to place mirrors or lenses — is enormous. Researchers at the Max Planck Institute for the Science...
Delivering medicines with microscopic flowers
Dec 10, 2024 (Nanowerk News) How can medicines be directed to the precise location within the body where they need to act? Scientists have been researching this question for a long time. An example would be delivering cancer drugs directly to a tumour so that they only take effect at...
Breakthrough in the precision engineering of four-stranded beta-sheets
Dec 10, 2024 (Nanowerk News) A newly developed approach can precisely produce four-stranded β-sheets through metal–peptide coordination, report researchers from Institute of Science Tokyo. Their innovative methodology overcomes long-standing challenges in controlled β-sheet formation, including fibril aggregation and uncontrolled isomeric variation in the final product. This breakthrough could advance the...
