May 11, 2023 (Nanowerk News) A research team from the National University of Singapore (NUS) Faculty of Science, led by Professor Liu Xiaogang from the Department of Chemistry, has developed a 3D imaging sensor that has an extremely high angular resolution, which is the capacity of an optical instrument to...
Hidden supermassive black holes brought to life by galaxies on collision course
May 11, 2023 (Nanowerk News) Astronomers have found that supermassive black holes obscured by dust are more likely to grow and release tremendous amounts of energy when they are inside galaxies that are expected to collide with a neighbouring galaxy. The new work, led by researchers from Newcastle University, is...
Researchers find new approach to explore earliest universe dynamics with gravitational waves
May 11, 2023 (Nanowerk News) Researchers have discovered a new generic production mechanism of gravitational waves generated by a phenomenon known as oscillons, which can originate in many cosmological theories from the fragmentation into solitonic “lumps” of the inflaton field that drove the early Universe’s rapid expansion, reports a new...
Channeling mechanical energy in a preferred direction
May 10, 2023 (Nanowerk News) A research group led by scientists from the RIKEN Center for Emergent Matter Science have developed a unique material, based on nanofillers embedded in a hydrogel, that can channel mechanical energy in one direction but not the other, acting in a “nonreciprocal” way. Using the...
New method uses Engineered bacteria and AI to sense and record environmental signals
May 10, 2023 (Nanowerk News) Researchers in Biomedical Engineering Professor Tal Danino’s lab were brainstorming several years ago about how they could engineer and apply naturally pattern-forming bacteria. There are many bacteria species, such as Proteus mirabilis (P. mirabilis), that self-organize into defined patterns on solid surfaces that are visible...
Nanotechnology enhances the effectiveness of T cells that attack tumors
May 10, 2023 (Nanowerk News) Vanderbilt researchers are bolstering the fight against cancer with technology that enhances the effectiveness of T cells that attack tumors. The cutting-edge research was recently published in the journal Science Immunology ("STING-activating nanoparticles normalize the vascular-immune interface to potentiate cancer immunotherapy"). Fluorescent microscopy of a...
Researchers develop injectable graphene-based bioelectrodes with tunable lifetimes
May 10, 2023 (Nanowerk News) Implantable bioelectrodes are electronic devices that can monitor or stimulate biological activity by transmitting signals to and from living biological systems. Such devices can be fabricated using various materials and techniques. But, because of their intimate contact and interactions with living tissues, selection of the...
Galactic bubbles are more complex than imagined
May 09, 2023 (Nanowerk News) Astronomers have revealed new evidence about the properties of the giant bubbles of high-energy gas that extend far above and below the Milky Way galaxy’s center. In a study recently published in Nature Astronomy ("Thermal and chemical properties of the eROSITA bubbles from Suzaku observations"),...
A new nondestructive method for assessing bioengineered artificial tissues
May 09, 2023 (Nanowerk News) Engineering organs to replace damaged hearts or kidneys in the human body may seem like something out of a sci-fi movie, but the building blocks for this technology are already in place. In the burgeoning field of tissue engineering, live cells grow in artificial scaffolds...
Exciting possibilities with amorphous MXene materials
May 09, 2023 (Nanowerk Spotlight) Scientists have recently discovered a new class of amorphous nanomaterials that are created by introducing atomic irregular arrangements. These materials demonstrate excellent performance in catalysis, energy storage, and mechanics. In a recent Perspective article in Advanced Materials ("Amorphous MXene Opens New Perspectives"), scientists explore the...
