Jun 11, 2024 (Nanowerk News) Researchers at Hokkaido University have developed a new and more adaptable method for creating nanoparticles of finely controlled size. Their ‘bio-catalytic nanoparticle shaping’ (BNS) procedure, published in the journal Nanoscale Horizons ("Bio-catalytic nanoparticle shaping for preparing mesoscopic assemblies of semiconductor quantum dots and organic molecules"),...
Novel 3D light field enables nanometric sensing and rapid microstructure fabrication
Jun 10, 2024 (Nanowerk Spotlight) The ability to precisely measure and manipulate matter at the nanoscale has emerged as a frontier of paramount importance. From unraveling the fundamental physics of quantum systems to engineering the next generation of ultrahigh density microchips, the capacity to interact with the world at its...
Scientists break limits of optical measurement using quantum entanglement
Jun 10, 2024 (Nanowerk News) The Korea Research Institute of Standards and Science (KRISS) has developed a novel quantum sensor technology that allows the measurement of perturbations in the infrared region with visible light by leveraging the phenomenon of quantum entanglement. This will enable low-cost, high-performance IR optical measurement, which...
A Martian dawn reveals a view of the red planet’s frosty, volcanic dew
Jun 10, 2024 (Nanowerk News) Water frost has been observed at the peaks of tall, ancient Martian volcanoes on cold mornings, reports a study published in Nature Geoscience ("Evidence for transient morning water frost deposits on the Tharsis volcanoes of Mars"). The findings support the role of localised atmospheric circulation...
Webb telescope reveals asteroid collision in neighboring star system
Jun 10, 2024 (Nanowerk News) Astronomers have captured what appears to be a snapshot of a massive collision of giant asteroids in Beta Pictoris, a neighboring star system known for its early age and tumultuous planet-forming activity. The observations spotlight the volatile processes that shape star systems like our own,...
Researchers develop first-in-kind protocol for creating ‘wired miniature brains’
Jun 10, 2024 (Nanowerk News) Researchers worldwide can now create highly realistic brain cortical organoids — essentially miniature artificial brains with functioning neural networks — thanks to a proprietary protocol released this month by researchers at the University of California San Diego. The new technique, published in Nature Protocols ("Generation...
Nanoparticles reprogram mouse immune systems to suppress food allergy
Jun 10, 2024 (Nanowerk News) Two doses of allergen-encapsulating nanoparticles delivered intravenously prevented anaphylaxis during a food allergy test in mice, according to a study led by University of Michigan researchers. The results, published in Advanced Healthcare Materials ("Allergen-encapsulating nanoparticles reprogram pathogenic allergen-specific Th2 cells to suppress food allergy"), offer...
Many nearby star clusters originate from only three ‘families’
Jun 10, 2024 (Nanowerk News) An international team of astronomers led by the University of Vienna has deciphered the formation history of young star clusters, some of which we can see with the naked eye at night. The team, led by Cameren Swiggum and João Alves from the University of...
The solar system may have passed through dense interstellar clouds 2 million years ago, altering Earth’s climate
Jun 10, 2024 (Nanowerk News) Around two million years ago, Earth was a very different place, with our early human ancestors living alongside saber-toothed tigers, mastodons, and enormous rodents. And, depending on where they were, they may have been cold: Earth had fallen into a deep freeze, with multiple ice...
