By combining two-dimensional materials, researchers create a macroscopic quantum entangled state emulating rare earth compounds.
COVID-19 facemasks & marine plastic pollution.
Our oceans will be flooded with an estimated 1.56 billion face masks in 2020 says a report released today by Hong-Kong-based marine conservation organization OceansAsia. This will result in an additional 4,680 to 6,240 metric tonnes of marine plastic pollution, says the report, entitled “Masks on the Beach: The Impact of COVID-19 on Marine Plastic Pollution.” These masks will take as long as 450 years to break down, slowly turning into micro plastics while negatively impacting marine wildlife and ecosystems.
The report used a global production estimate of 52 billion masks being manufactured in 2020, a conservative loss rate of 3%, and the average weight of 3 to 4 grams for a single-use polypropylene surgical face mask to arrive at the estimate.

When physicist Tyler Cocker joined Michigan State University in 2018, he had a clear goal: build a powerful microscope that would be the first of its kind in the United States.
Having accomplished that, it was time to put the microscope to work.
“We knew we had to do something useful,” said Cocker, Jerry Cowen Endowed Chair in Experimental Physics in the College of Natural Science’s Department of Physics and Astronomy. “We’ve got the nicest microscope in the country. We should use this to our advantage.”
The findings could inform the design of new materials such as iridescent windows or waterproof textiles.
If you brush against the wings of a butterfly, you will likely come away with a fine sprinkling of powder. This lepidopteran dust is made up of tiny microscopic scales, hundreds of thousands of which paper a butterfly’s wings like shingles on a wafer-thin roof. The structure and arrangement of these scales give a butterfly its color and shimmer, and help shield the insect from the elements.

“A combination of grassy notes with a tang of acids and a hint of vanilla over an underlying mustiness” is how an international team of chemists describes the unique odor of old books in a study. Poetic, sure, but what causes it?
Books are made up almost entirely of organic materials: paper, ink, glue, fibers. All these materials react to light, heat, moisture, and even each other over the years, and release a number of volatile organic compounds (VOCs). While the blend of compounds released by any one book is dependent on the exact things that went into making it, there’s only so much variation in materials.
The researchers tested 72 books and found some 15 compounds that came up again and again. They were reliable markers for degradation. These include acetic acid, benzaldehyde, butanol, furfural, octanal, methoxyphenyloxime, and other chemicals with funny-sounding names. A book’s smell is also influenced by its environment and materials it encounters over the course of its life (which is why some books have hints of cigarette smoke, others smell a little like coffee, and still others, cat dander).
Mechanical metamaterials can be engineered with properties not possible in ordinary materials. Here the authors demonstrate and study an active metamaterial with self-sensing characteristics that enables odd elastic properties not observed in passive media.
I may have already posted about this, but this is more data from The Lancet.
Background.
Recent evidence indicates a potential therapeutic role of fluvoxamine for COVID-19. In the TOGETHER trial for acutely symptomatic patients with COVID-19, we aimed to assess the efficacy of fluvoxamine versus placebo in preventing hospitalisation defined as either retention in a COVID-19 emergency setting or transfer to a tertiary hospital due to COVID-19.
Scientists demonstrate how quantum entanglement can be witnessed in the quasi-1D Heisenberg antiferromagnet.
If you own any piece of jewelry with a ruby, you’re probably never going to look at it the same way again.
Forget those perfect gemstones you see glittering in store displays. What scientists are looking for are the flawed ones — the ones that contain inclusions which can whisper the secrets of Earth’s distant past, like that tardigrade trapped in amber. When researcher Chris Yakymchuk and his team unearthed a peculiar ruby in Greenland, the inclusion they found was what remained of life that was over 2.5 billion years old.
What was inside the ruby sounds common enough. Graphite is the same material pencils write with, but it is also a pure form of carbon that Yakymchuk determined to be all that was left of prehistoric microbes, possibly the same cyanobacteria (blue-green algae) that first released oxygen into Earth’s atmosphere through photosynthesis. He led a study recently published in Ore Geology Reviews.
