Sep 20, 2022 (Nanowerk News) People have been exploring the surface of Mars for over 50 years. According to the United Nations Office for Outer Space Affairs, nations have sent 18 human-made objects to Mars over 14 separate missions. Many of these missions are still ongoing, but over the decades...
Facemask can detect viral exposure from a 10-minute conversation with an infected person
Sep 20, 2022 (Nanowerk News) Scientists have created a face mask that can detect common respiratory viruses, including influenza and the coronavirus, in the air in droplets or aerosols. The highly sensitive mask, presented in the journal Matter ("Wearable bioelectronic masks for wireless detection of respiratory infectious diseases by gaseous...
Researchers test hybrid, soft/hard nanocarriers to deliver drugs to the brain
Sep 20, 2022 (Nanowerk News) Rizia Bardhan made a fist with one hand then covered it with her other hand, like a baseball player catching a ball in the web of a fielder’s glove. The fist represents a special nanocarrier filled with medicine, said the Iowa State University associate professor...
Researchers advance efforts to tailor drug delivery to cells’ ‘power plants’
Sep 20, 2022 (Nanowerk News) In a study using lab-grown cells, Johns Hopkins Medicine researchers specializing in aging report they have successfully delivered a common blood pressure drug directly to the inner membrane of mitochondria, the “power plants” in the cells of humans, animals, plants and most other organisms. Developing...
Silicon nanopillars for quantum communication
Sep 20, 2022 (Nanowerk News) Across the world, specialists are working on implementing quantum information technologies. One important path involves light: Looking ahead, single light packages, also known as light quanta or photons, could transmit data that is both coded and effectively tap proof. To this end, new photon sources...
High-performance and high-reliability artificial synaptic semiconductor device for next-generation brain-mimicking computing
Sep 20, 2022 (Nanowerk News) Neuromorphic computing system technology mimicking the human brain has emerged and overcome the limitation of excessive power consumption regarding the existing von Neumann computing method. A high-performance, analog artificial synapse device, capable of expressing various synapse connection strengths, is required to implement a semiconductor device...
Earth-like exoplanets unlikely to be another ‘pale blue dot’
Sep 20, 2022 (Nanowerk News) Tilman Spohn and Dennis Höning studied how the evolution and cycles of continents and water could shape the development of terrestrial exoplanets. Results from their models suggest that planets have approximately an 80 percent probability of being mostly covered by land, with 20 percent likely...
