I'm sure you have all been wondering, like I have, what species of grass are considered acceptable for grass tennis courts. It appears the type of grass is not mandated, according to Tennis Australia's National Court Surface Policy's description of a grass court is natural grass grown from seed.

Here are some grasses that I propose we make grass courts out of: 1. Blue Fescue Grass – Festuca glauca

2. Windmill Grass – Chloris truncata

3. Snow Grass – Poa sieberiana

4. Zebra grass (Miscanthus sinensis 'Zebrinus')

5. Purple fountain grass (Pennisetum setaceum 'Rubrum')

6. Pink muhly grass (Muhlenbergia capillaris)

Physical surface details of mica studied on an atomic scale

At first glance, mica is something quite ordinary: it is a common mineral, found in granite for example, and has been extensively studied from geological, chemical and technical perspectives.

One might think that nothing new can be discovered from such an everyday material. But now a team from the Vienna University of Technology has presented a study in the journal Nature Communications, explaining the distribution of potassium ions on the mica surface. The physical surface details of mica have never been studied on an atomic scale, and this information is important for research on electronics with 2D materials.

Atomically thin layers

Atomically thin–layered 2D materials are currently one of the most researched topics in materials science. Certain materials, such as graphene and molybdenum disulfide, consist of only one or a few layers of atoms, which frequently leads to unusual properties.

you know, tbh, i really do get why some ppl hate Xander so much that they find him completely unwatchable as a character. not me though, i get him.

op do you know how fucking funny it is coming home from studying for mineralogy (sitting in a lab looking at minerals in hand sample & Microscop) for 6 hours only to be greeted with my beloved mutual Blank systemaltoclef to be, of all things, posting about minerals?

Do you know my hell?

omg no we do not know your hell ... we were at whole foods and they had overpriced rocks (bc whole foods) and we went omg... we love overpriced rocks (we did not get the rocks) but then we googled how they make quartz do the iridescence thing and thinking about lab quartz triggered the vague memory of Quartz Slurry Post upon which we naturally had to hunt it down to reblog once more. but what a coincidence

While researching for upcoming fish facts I ended up going down a rabbit hole on parrotfish teeth, and I need to share this information in another form than just a fish fact. This stuff is unbelievable. You know the beak of the parrotfish, right? It's formed from the fused teeth of the parrotfish, as an adaptation to have ample biting surface to scrape off and chew on coral, their main food source.

A close-up of the beak of a parrotfish. It has this honeycomb pattern which I find very cool.

Well. To constantly chew on coral, they must have some pretty hard teeth, right? And they indeed do: the teeth of the parrotfish are made up of a mineral called fluorapatite, which forms intricate, chainmail-like woven structures on a microscopic level. Fluorapatite just so happens to be the second hardest biomineral found. This stuff, the parrotfish's teeth? A square inch of the parrotfish's teeth can withstand a whopping 530 TONS OF PRESSURE!!! That's the weight of 88 ELEPHANTS on top of a single square inch!!!! That's crazy, right!!?? The only biomineral that is tougher is the teeth of chitons, that is the single tougher biological thing in the whole world!!! Not only that, but the stiffness and hardness of the teeth increases the more we get closer to the tip (as the mineral fibers get closer and closer to one another), the very tips of the teeth even surpass the chiton teeth in stiffness!!!

Here are pictures produced through a process called PIC mapping, which shows the size and orientation of crystal fibers at the tip of the teeth.

That feels like it shouldn't be right, no? You'd think that the toughest biominerals in the world would belong to, like, the skull of an animal that rams into rocks or maybe the shell of some animal, not the teeth! The teeth of chitons and parrotfish out of all animals no less! Who would've guessed that the diet of "rock animal" would make the parrotfish require some of the toughest dentition the world has ever seen, huh? That right there is one super good reason why you should never stick your finger in the mouth of one.

Every day I am blown away by how amazing fishes are....

"The story of  'John Doe 1' of the Democratic Republic of the Congo is tucked in a lawsuit filed five years ago against several U.S. tech companies, including Tesla, the world’s largest electric vehicle producer. In a country where the earth hides its treasures beneath its surface, those who chip away at its bounty pay an unfair price. As a pre-teen, his family could no longer afford to pay his $6 monthly school fee, leaving him with one option: a life working underground in a tunnel, digging for cobalt rocks.  But soon after he began working for roughly two U.S. dollars per day, the child was buried alive under the rubble of a collapsed mine tunnel. His body was never recovered. 

The nation, fractured by war, disease, and famine, has seen more than 6 million people die since the mid-1990s, making the conflict the deadliest since World War II. But, in recent years, the death and destruction have been aided by the growing number of electric vehicles humming down American streets. In 2022, the U.S., the world’s third-largest importer of cobalt, spent nearly $525 million on the mineral, much of which came from the Congo.

As America’s dependence on the Congo has grown, Black-led labor and environmental organizers here in the U.S. have worked to build a transnational solidarity movement. Activists also say that the inequities faced in the Congo relate to those that Black Americans experience. And thanks in part to social media, the desire to better understand what’s happening in the Congo has grown in the past 10 years. In some ways, the Black Lives Matter movement first took root in the Congo after the uprising in Ferguson in 2014, advocates say. And since the murder of George Floyd and the outrage over the Gaza war, there has been an uptick in Congolese and Black American groups working on solidarity campaigns.

Throughout it all, the inequities faced by Congolese people and Black Americans show how the supply chain highlights similar patterns of exploitation and disenfranchisement. ... While the American South has picked up about two-thirds of the electric vehicle production jobs, Black workers there are more likely to work in non-unionized warehouses, receiving less pay and protections. The White House has also failed to share data that definitively proves whether Black workers are receiving these jobs, rather than them just being placed near Black communities. 'Automakers are moving their EV manufacturing and operations to the South in hopes of exploiting low labor costs and making higher profits,' explained Yterenickia Bell, an at-large council member in Clarkston, Georgia, last year. While Georgia has been targeted for investment by the Biden administration, workers are 'refusing to stand idly by and let them repeat a cycle that harms Black communities and working families.'

... Of the 255,000 Congolese mining for cobalt, 40,000 are children. They are not only exposed to physical threats but environmental ones. Cobalt mining pollutes critical water sources, plus the air and land. It is linked to respiratory illnesses, food insecurity, and violence. Still, in March, a U.S. court ruled on the case, finding that American companies could not be held liable for child labor in the Congo, even as they helped intensify the prevalence. ... Recently, the push for mining in the Congo has reached new heights because of a rift in China-U.S. relations regarding EV production. Earlier this month, the Biden administration issued a 100% tariff on Chinese-produced EVs to deter their purchase in the U.S. Currently, China owns about 80% of the legal mines in the Congo, but tens of thousands of Congolese work in 'artisanal' mines outside these facilities, where there are no rules or regulations, and where the U.S. gets much of its cobalt imports.  'Cobalt mining is the slave farm perfected,' wrote Siddharth Kara last year in the award-winning investigative book Cobalt Red: How The Blood of the Congo Powers Our Lives. 'It is a system of absolute exploitation for absolute profit.' While it is the world’s richest country in terms of wealth from natural resources, Congo is among the poorest in terms of life outcomes. Of the 201 countries recognized by the World Bank Group, it has the 191st lowest life expectancy."
