It’s about sound: (1) Earable computing? (2) The end of the cacophony in hospitals?

I have two items, both concerning sound but in very different ways. Phones in your ears Researchers at the University of Illinois are working on smartphones you can put in your ears like you do an earbud. The work is in its very earliest stages as they are trying to establish a new field of research. There is a proposed timeline, Caption: Earable computing timeline, according to SyNRG.

Living plants detect arsenic by way of embedded nanosensors

There’s a lot of arsenic in the world and it’s often a factor in making water undrinkable. When that water is used in farming It also pollutes soil and enters food-producing plants. A December 11, 2020 news item on Nanowerk announces research into arsenic detectors in plants, Researchers have developed a living plant-based sensor that can in real-time detect and monitor levels of arsenic, a highly toxic heavy metal, in the soil. Arsenic pollution is…

1st biohybrid artificial retina built with silk fibroin & retinal cells

A December 12, 2020 news item on Nanowerk announces a step forward in the development of artificial retinas, “The biohybrid retina is a cell therapy for the reconstruction of the damaged retina by implanting healthy cells in the patient’s eye,” says Fivos Panetsos, director of the Neuro-computation and Neuro-robotics Group of the UCM and member of the Institute of Health Research of the Hospital Clínico San Carlos de Madrid (IdISSC). A December 11, 2020 Universidad…

Why it’s important to customize corrosion testing to the application environment

Many industries in western Canada face corrosion problems due to the frequent exposure of metal alloys to water, salt, oxygen, carbon dioxide, hydrogen sulfide and lesser well-known sulfur compounds. In our lab, we test metal corrosion by simulating the environment in which it will be applied. Learn more.

Reading a virus like a book

Teaching grammar and syntax to artificial intelligence (AI) algorithms (specifically natural language processing (NLP) algorithms) has helped researchers understand and predict viral mutations more speedily. This facility is especially useful at a time when the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus seems to be mutating into more easily transmissible variants. Will Douglas Heaven’s Jan. 14, 2021 article for the Massachusetts Institute of Technology’s MIT Technology Review describes the work that links AI, grammar,…

Nanodiamond-embedded membrane filters for clean water

This December 9, 2020 news item on Nanowerk announces research into a nanodiamond filter which can clean hot wastewater, Although most of the planet is covered by water, only a fraction of it is clean enough for humans to use. Therefore, it is important to recycle this resource whenever possible. Current purification techniques cannot adequately handle the very hot wastewater generated by some industries.… A December 9, 2020 American Chemical Society (ACS) news release, which…

Self-repairing gelatin-based film for electronics?

A December 2, 2020 news item on phys.org announces research that might make shattered mobile phones a rare occurrence, Dropping a cell phone can sometimes cause superficial cracks to appear. But other times, the device can stop working altogether because fractures develop in the material that stores data. Now, researchers reporting in ACS [American Chemical Society] Applied Polymer Materials have made an environmentally friendly, gelatin-based film that can repair itself multiple times and still maintain…

Neuromorphic computing with a memristor is capable of replicating bio-neural system

There’s nothing especially new in this latest paper on neuromorphic computing and memristors, however it does a very good job of describing how these new computers might work. From a Nov. 30, 2020 news item on phys.org (Note: A link has been removed), In a paper published in Nano, researchers study the role of memristors in neuromorphic computing. This novel fundamental electronic component supports the cloning of bio-neural systems with low cost and power.Contemporary computing…
