These days I need a little joy and these two researchers seem happy to share, Prof. Dirk Grundler and doctoral assistant Sho Watanabe with a broadband spin-wave spectroscopy set up. Credit: EPFL / Alain Herzog A July 15, 2020 news item on phys.org announces the development that so delights these researchers, Researchers at EPFL [École polytechnique fédérale de Lausanne; Switzerland] have shown that electromagnetic waves coupled to precisely engineered structures known as artificial ferromagnetic quasicrystals…

Theories from mathematics, physics, and geology have been used to demonstrate that the earth’s basic shape is, roughly speaking, a cube. From a July 20, 2020 news item on ScienceDaily, Plato, the Greek philosopher who lived in the 5th century B.C.E. [before the common era], believed that the universe was made of five types of matter: earth, air, fire, water, and cosmos. Each was described with a particular geometry, a platonic shape. For earth, that…

A July 16, 2020 news item on Nanowerk announces some work from Rutgers University (New Jersey, US) where carbon dioxide could one day be converted into fuel or perhaps be used in quantum computers, Imagine tiny crystals that “blink” like fireflies and can convert carbon dioxide, a key cause of climate change, into fuels.A Rutgers-led team has created ultra-small titanium dioxide crystals that exhibit unusual “blinking” behavior and may help to produce methane and other…

I believe that swab they stick up your nose to test for COVDI-19 is 10 inches long so it seems to me that discomfort or unpleasant are not the words that best describe the testing experience . Hopefully, no one will have to find inadequate vocabulary for this new COVID-19 testing assuming that future trials are successful and they are able to put the technology into production. From an August 19, 2020 news item on…

Researchers at the University of Washington have developed a tiny camera that can ride aboard an insect. Here a Pinacate beetle explores the UW campus with the camera on its back. Credit: Mark Stone/University of Washington Scientists at Washington University have created a removable wireless camera backpack for beetles and for tiny robots resembling beetles. I’m embedding a video shot by a beetle later in this post with a citation and link for the paper,…
