Jan 25, 2023 (Nanowerk News) A new study led by a joint team at Nagoya University and the National Astronomical Observatory of Japan has measured the cosmic age of a very distant galaxy. The team used the ALMA radio telescope array to detect a radio signal that has been travelling...
Transistors repurposed as microchip ‘clock’ address supply chain weakness
Jan 25, 2023 (Nanowerk News) Microchip fab plants in the United States can cram billions of data processing transistors onto a tiny silicon chip, but a critical device, in essence a “clock,” to time the operation of those transistors must be made separately – creating a weak point in chip...
Nanofiber-hydrogel loaded with stem cells shows success treating severe complication of Crohn’s disease
Jan 25, 2023 (Nanowerk News) In a new study using a rat model of Crohn’s disease, a biodegradable hydrogel composite loaded with stem cells, developed by Johns Hopkins Medicine researchers, in a collaborative effort with the Whiting School of Engineering, has shown significant success in treating perianal fistulas (PAF) —...
Scientists generate and measure the shortest electron pulse to date
Jan 25, 2023 (Nanowerk News) By using ultrafast laser flashes, scientists at the University of Rostock in collaboration with researchers of the Max Planck Institute for Solid State Research in Stuttgart have generated and measured the shortest electron pulse to date. The electron pulse was created by using lasers to...
Tiny T-1000 terminator-like robot shifts between liquid and solid states, escapes tiny jail cell (w/video)
Jan 25, 2023 (Nanowerk News) International researchers have designed miniature legoman-like robots that can shift between liquid and solid states, like some kind of tiny T-1000 Terminator. The team put the magnetic and conductive robots through an obstacle course to test their mobility and shape-morphing abilities – tests included jumping...
The last mysteries of atomically thin mica
Jan 25, 2023 (Nanowerk News) At first glance, mica is something quite ordinary: it is a common mineral, found in granite for example, and has been extensively studied from geological, chemical and technical perspectives. One might think that nothing new can be discovered from such an everyday material. But now...
Spinning food processing waste into ‘gold’
Jan 25, 2023 (Nanowerk News) There is money to be made – and potential to reduce greenhouse gas emissions – by finding a second life for the potato peels, fried dough particles, cheese whey and other industrial food-processing waste products that routinely end up in landfills, according to new research....
Fish sensory organ key to improving navigational skills of underwater robots
Jan 25, 2023 (Nanowerk News) Scientists, led by University of Bristol, have been studying a fish sensory organ to understand cues for collective behaviour which could be employed on underwater robots (Royal Society Open Science, "Lateral line morphology, sensory perception and collective behaviour in African cichlid fish"). This work was...
New DNA biosensor could unlock powerful, low-cost clinical diagnostics
Jan 24, 2023 (Nanowerk News) DNA can signal the presence of or predisposition to a slew of diseases, including cancer. The ability to flag down these clues, known as biomarkers, allows medical professionals to make critical early diagnoses and provide personalized treatments. The typical methods of screening can be laborious,...
Spin transport measured through molecular films now long enough to develop spintronic devices
Jan 24, 2023 (Nanowerk News) A research group, at the Osaka Metropolitan University Graduate School of Engineering, has succeeded in measuring spin transport in a thin film of αNPD molecules—a material well-known in organic light emitting diodes—at room temperature. They found that this thin molecular film has a spin diffusion...
