📰 Wet coffee waste becomes coal-grade fuel in under two minutes

🗒 "The material’s specific surface area also increased substantially, producing a porous carbon product with uses beyond fuel: activated carbon production, filtration, and industrial adsorption."

💬 I was conflicted about this one, but the above quote made me decide to still share it

Oyster Reefs Sequester Nitrogen

The US eastern seaboard was once blanketed with oyster beds, but overharvesting, pollution, and habitat destruction decimated the population. As filter-feeders, oysters are naturally good at cleaning intertidal zones, and the reefs they build by cementing themselves to one another provide valuable habitat for many species of fish. A new study shows that oysters are even more economically valuable than we knew, thanks to their ability to sequester nitrogen.

Agricultural and industrial run-off carries nitrates into the ocean in high concentrations that trigger deadly phytoplankton blooms, which choke off oxygen levels for larger species like fish. One way to reduce nitrogen levels in the water is denitrification, a process where microbes break down the nitrate into, among other things, inert nitrogen gas. The surface of oyster reefs is one place where this happens. But nitrates that evade these microbes can also get trapped and buried by a growing oyster reef.

To understand how much nitrogen an oyster reef can bury, researchers studied cores removed from restored oyster beds. Below the top ten centimeters (where microbes do their denitrification), nitrogen levels in the oysters increased, with a square meter of oyster reef, on average, sequestering 6 grams of nitrogen per year, comparable to the amount that microbes removed. But some oyster reefs outperformed others. In particular, intertidal flat reefs–which grow faster–buried more than twice the nitrogen of subtidal reefs.

The team estimated that, in North Carolina’s Carteret County, oyster reefs sequester some 120,000 kilograms of nitrogen annually, at an economic value of over $3 million. (Image credit: J. Andrews/UNC-Chapel Hill; research credit: A. Smiley et al.; via Eos)

So, I was refused at my eighth or ninth hair salon in midtown Manhattan today. With the weather change, I widened my search and asked more salons if they'd cut my hair on the sidewalk. $25 - $100, all have said no.
It finally came out that the city won't allow it, so they might have been worried about a ticket? The city says that hair might go places, I guess...

Each COVID infection increases your risk of Long-COVID. If you have underlying conditions, are Hispanic/ Latino, and/ or are female, you are at higher risk than others for Long-COVID.
If you get 2 infections: you are 2.14 times more likely to get Long-COVID.
If you get 3 or more infections: you are 3.75 times more likely to get Long-COVID (another study found this).

People can protect themselves by staying indoors or by wearing #N95masks, she said. Strykowski added that they must be N95s because the cloth #masks many people used during the COVID-19 pandemic don’t provide enough #filtration.

[My additional advice: be sure to always carry your rescue #inhaler!! If you can use an allergy #filter on your HVAC system. Close your windows & use an indoor air filter machine.]

Filtering Like a Manta Ray

As manta rays swim, they’re constantly doing two important — but not necessarily compatible — things: getting oxygen to breathe and collecting plankton to eat. That requires some expert filtering to send food particles toward their stomach and oxygen-rich water to their gills. Manta rays do this with a built-in filter that resembles an industrial crossflow filter. Researchers built a filter inspired by a manta ray’s geometry, and found that it has three different flow states, based on the flow speed. At low speeds, flow moves freely down the filter’s channels; in a manta, this would carry both water and particles toward the gills. At medium speeds, vortices start to form at the entrance to the filter channels. This sends large particles downstream (toward a manta’s digestive system) while water passes down the channels. At even greater speeds, each channel entrance develops a vortex. That allows water to pass down the filter channels but keeps particles out. (Image credit: manta – N. Weldingh, filter – X.
