Nov 23, 2023 (Nanowerk News) Hopfions, magnetic spin structures predicted decades ago, have become a hot and challenging research topic in recent years. In a study published in Nature ("Hopfion rings in a cubic chiral magnet"), the first experimental evidence is presented by a Swedish-German-Chinese research collaboration. “Our results are...
Biomimetic soft robotic design mimics plant twining behavior
Nov 23, 2023 (Nanowerk News) For decades, researchers have marveled at the remarkable capabilities of biological structures like elephant trunks, octopus arms, and climbing plants. These natural continuum structures exhibit an enviable versatility and adaptability despite possessing no central control unit or “brain.” Scientists have long sought to replicate such...
Synthetic microbots mimic plankton to achieve 3D motion
Nov 23, 2023 (Nanowerk News) For decades, researchers have sought to emulate the collective behavior of natural systems like schools of fish or flocks of birds using synthetic microscale robots. Such robot collectives could enable a variety of applications, from targeted drug delivery to environmental remediation. However, realizing robust 3D...
Extreme stars share unique properties that may provide a link to mysterious sources
Nov 23, 2023 (Nanowerk News) An international research team led by Michael Kramer and Kuo Liu from the Max Planck Institute for Radio Astronomy in Bonn, Germany, have studied a rare species of ultra-dense stars, so called magnetars, to uncover an underlying law that appears to apply universally to a...
Revolutionary breakthrough in the manufacture of photovoltaic cells
Nov 23, 2023 (Nanowerk News) The University of Ottawa, together with national and international partners, has achieved a world first by manufacturing the first back-contact micrometric photovoltaic cells. This innovative achievement is described in more detail in Cell Reports Physical Science ("3D interconnects for III-V semiconductor heterostructures for miniaturized power...
New nanotechnology makes water harvesting from air far easier
Nov 23, 2023 (Nanowerk Spotlight) For over half the global population, accessing clean drinking water remains an enduring challenge. With climate change and development pressures exacerbating water scarcity worldwide, innovative solutions are desperately needed. Atmospheric water harvesting – the extraction of drinkable water directly from humid air – offers immense...
‘Amaterasu’ particle: a new cosmic mystery
Nov 23, 2023 (Nanowerk News) A high-energy particle falls from space to the Earth’s surface – it is not clear where it came from or even what it is, exactly. This may sound like something out of science fiction, but it is in fact a scientific reality, as evidenced by...
‘Triple star’ discovery could revolutionise understanding of stellar evolution
Nov 22, 2023 (Nanowerk News) A ground-breaking new discovery by University of Leeds scientists could transform the way astronomers understand some of the biggest and most common stars in the Universe. The findings have been published in Monthly Notices of the Royal Astronomical Society ("Gaia uncovers difference in B and...
Dwarf galaxies use 10-million-year quiet period to churn out stars
Nov 22, 2023 (Nanowerk News) If you look at massive galaxies teeming with stars, you might be forgiven in thinking they are star factories, churning out brilliant balls of gas. But actually, less evolved dwarf galaxies have bigger regions of star factories, with higher rates of star formation. Now, University...
CRISPR-powered optothermal nanotweezers allow targeted manipulation of single DNA molecules
Nov 22, 2023 (Nanowerk News) For decades, researchers have sought ways to precisely manipulate and identify individual molecules like DNA in liquid environments. Such capabilities could revolutionize areas ranging from disease diagnosis to drug development. However, the randomness of molecular movements in fluids has hindered progress. Now, scientists from Shenzhen...
