There has been an increase of Metas all over the US in the past week and all of them are under the age of 20 they travel in groups and are being chased by people in white

All of the kids that were 19 and below had to run from Amity Park when the GIW found out that they were Liminal, The adults that cared helped the kids and their friends out of the city before the GIW took them.

This is a different version of # 60 but instead of the adults leaving the kids leave

So. In the episode Micro Management. Jack Fenton says that his Fenton Crammer is able to "shrink ghosts."

And while the Crammer does shrink ghosts. -aka Skulker and Danny-

You know who else it shrinks? Dash.

So that begs the question.

Is Dash fully human?

my hot take is the whole "search for life in the universe" thing is truly just a spin to put sparkle in children's eyes and make dumb congresspeople who like the idea of aliens fund science that actually helps people

the endeavors bring about a ton of great science that is related to health and ecology and atmospheric monitoring and all sorts of stuff and understanding how our planet and life was former and the scientists who do this research and stare at radiograms and try to figure out if that chemical stretch is a C-S or a C-C or a C-O bond, are amazing scientists

but god do I have no interest in "uwu we might have found signs of life on other planets!"

the first time was vaguely neat, now we know it's entirely possible and not novel and probably there's phytoplankton (at best) in some ocean planets that we will never ever visit woo hoo

most of the astro people I know working on these projects are mostly interested in the spectroscopy part too and not the whole search for alien life thing so it's very hard for me to look at the press releases with anything but weariness

no one's interested when we figure out what metals are in the active sites of proteins or that actually a redox inactive metal mutated into this other protein actually increases its activity bc the mechanism involves redox active ligands and cofactors, rather than the metal itself. just. you know. as an example. but every time there's a little blip of "oh there's NOx and SOx and VOCs on another distant planet according to this one spectra--" gets a front page news thing.

oh don't do that. don't give me the banter dialogue option. don't give me that cause i Will pick it and then i'll be bantering with emet-selch and its gonna be all downhill from there i just know it

I'm trying not to use "hypothetical" in my peer review of someone's op-ed on nuclear energy but how else do I address: "but how about the elderly person that gets poisoned from growing a carrot in their contaminated ground?  Science at this point has not documented the long-term effects of nuclear energy and has left many questions unanswered."

yeah alright. let's go ahead and use the evidence of no evidence ig

Relevant additions from OP [emjaydoubleyou] in the replies:

btw i hope it’s obvious that i’m not saying: -you shouldn’t care about these results -you are unreasonable if you decide to stop wearing tampons over this or any other reason or even just vibes. your business and no one else’s! -that i uncritically believe tampon companies have our best interests at heart however, it is wildly irresponsible to tell people to stop wearing tampons at all costs, and to spread the word to potentially Save A Life. such warnings are not supported by this research and are not endorsed by the authors of the paper. i felt compelled to say something. oh, and as this post mentions menstruation and misogyny, just want to explicitly state that this post is trans inclusive, and the choice to describe “human” health was deliberate.

The original original post has reblogs turned off by now, so I'm going to link some good "debunks" with more information from the reblogs there: Information on deciphering scientific studies and Putting the study's results into perspective.

this post is fearmongering. the results of this study are concerning and should definitely be a matter of public discussion, but this is certainly not the conclusion the researchers came to.

the point of the study was to assess the risks of exposure to toxic metals- something one of the co-authors notes are “ubiquitous” fwiw- via menstrual products. Their research confirmed that these metals are indeed present in tampons, but no further conclusions are drawn. it is possible the metal entered into the cotton from the soil, which is a well-known phenomenon; cotton is so good at lifting heavy metals that it has actually been suggested as a part of the solution for revitalizing polluted ground.

the authors conclude with an acknowledgement that the study should be repeated- their sample size was 60 tampons- and a suggestion that further testing ought to be done to indicate whether or not these metals can even leech out of the tampon in the first place, let alone whether or not such leeching could occur at levels deleterious to human health.

there is, in fact, a body of research- too small, for sure, but much larger than this single study- indicating that long-term proper tampon use has no observable negative impact on health. i am grateful and thrilled that more research is being done and i hope that this study is the first of many on this line of questioning, but i am really frustrated at this post and the response it got.

obviously, if this study alters your approach to menstrual health, more power to you. consumers should be informed-risk-takers, and menstrual health is double-obviously a very personal choice. but it definitely wasn't the researchers concluding that you ought to “avoid using tampons at all cost," only this tumblr user did. the lead author of the paper, in fact, specifically says that she hopes people do NOT panic about the results.

(the notes of the post were disappointing. people affirming that they knew they were right to be suspicious of tampons all along, or even recommending alternatives that actually have very little to no research regarding the safety of long-term use, etc. it’s a different conversation, but categorical distrust of tampons is old-school misogyny. you certainly shouldn't wear them if you don’t want to, but there is nothing inherently scary or wrong about them, and people who prefer them are not being reckless or crass.)

((if you're really worried about exposure to heavy metals, you may want to turn a critical eye to fast fashion, as an aside))

A new study finds you can reduce the amount of microplastics you drink simply by boiling your water.

Scientists are just beginning to understand the health risks associated with microplastic exposure.

Nano- and microplastics are bits of plastic as tiny as one-thousandth of a millimeter in diameter.

Boiling and filtering your tap water may dramatically lower the amount of microplastics you drink, according to new research.

Recent studies have found that nano- and microplastics (NMPs), which are bits of plastic as tiny as one-thousandth of a millimeter in diameter, have been found in a host of products and even in tap water.

A new study, published February 28 in Environmental Science & Technology Letters, found that boiling mineral-rich water for just five minutes can reduce the amount of NMP you’re exposed to by up to 90%.

Scientists are just beginning to understand the health risks associated with microplastic exposureTrusted Source, but growing evidenceTrusted Source suggests the plastics can accumulate in the body and trigger oxidative stress, inflammation, insulin resistance, and liver issues.

Certain advanced water filtration systems can capture and help remove some NMPs from tap water. But researchers wanted to figure out other options to remove microplastics, especially since in poorer countries cheaper, more accessible solutions for clean water are needed.

Boiling water may be a safe, simple solution that can effectively decontaminate household tap water, the new findings suggest.

“Boiling water before drinking is a great example of an ancient cultural practice that can help reduce an environmental exposure,” Dr. Luz Claudio, PhD, a professor of environmental medicine and public health at the Icahn School of Medicine at Mount Sinai, told Healthline.

Claudio was not involved in the study.

How boiling water can help remove microplastics

The researchers found simply boiling water is the first step to removing NMPs from tap water.

The researchers collected multiple samples of tap water from Guangzhou, China and contaminated the samples with varying levels of NMPs.

Each sample was boiled for five minutes then left to cool for 10 minutes.

Boiling hard water that’s rich with minerals — such as calcium or magnesium — creates a chalk-like residue known as limescale, or calcium carbonate (CaCO3), which can trap the plastics.

That solid, chalky residue then had to be separated and removed from the water with a standard coffee filter or stainless steel filter, thereby removing NMPs.

The team found that the impact was greatest in harder water: In samples that had 300 milligrams of CaCO3, for example, nearly 90% of NMPs were removed.

In softer water samples with less than 60 mg of CaCO3, roughly 25% of NMPs were removed.

“What’s important to note here is that the effectiveness of trapping these micro/nano plastics in these mineral solids is tied to how hard the water is – the harder the water, the more solids are formed, the more microplastics are trapped,” Dr. Anja Brandon, PhD, the associate director of U.S. plastics policy at Ocean Conservancy and an environmental engineer, told Healthline.

Brandon was not involved in the study...

How to limit your exposure to microplastics 

Anyone who wishes to boil their water should do so in a glass or stainless steel pot.

After boiling the water for about five minutes, let it cool, and do not stir it, Claudio says.

The microplastics need to bind to the calcium and fall to the bottom of the pot so they can filtered or scooped out."

Global study reveals extensive impact of metal mining contamination on rivers and floodplains.

Dear Friends,

My family in Northern Gaza is enduring severe hardship. With power and communication outages, they face darkness and isolation. They struggle daily with a shortage of food, vegetables, and safe drinking water. Long waits in water queues and diseases from contaminated water are part of their daily reality.

Hospitals have been destroyed, and they now live in tents under the harsh summer heat. My siblings, once top students, are now focused on finding basic necessities instead of their studies, which adds to their suffering.

Seeing their gaunt faces and the brutal scenes they witness daily is heart-wrenching. I wonder: Will the children of Gaza ever escape these horrors?

Thanks to your generous support, we've raised €6,513 of our €50,000 goal, covering the initial coordination for my younger brother. I’m deeply grateful for your contributions and help in spreading the campaign. However, we still need to secure the rest of the family.

Our next goal is to raise an additional €3,487 by the end of this week to reach a total of €10,000. This amount will cover the costs for both my younger brother and sister.

Our campaign is verified by el-shab-hussein and is listed on their vetted fundraisers at #281, line 285.

Please continue to support and share the campaign. Every share and donation helps reduce their suffering and brings us closer to our goal.

Thank you for your continued support and generosity.

bff james w no boundaries — his main love language is physical touch and that includes biting,, like 😭 you’ll just be minding ur own business n he’ll bite your shoulder or anywhere really.

hope ur doing well angel. ❤️

"Here, Remus," You offer up a spoon of blueberry tart to the teenage werewolf, unphased by now at the closeness of your friends. Perhaps at eleven you'd be worried about swapping cooties when sharing spoons, but now you're only worried about plumping Remus's gaunt frame up again before the next full moon.

You extend the spoon towards Remus but in doing so you have to bypass James who's sitting beside you on the bench. You'd expected him to fake a lunge for the sweet, but when he opens his mouth and sinks his teeth into what's in front of him it happens to be the flesh of your arm.

"Hey-ow!" You yelp, and despite your word choice, it doesn't really hurt. It's more of a grasp than it is a bite, just enough force to pin your arm between James's infuriatingly perfect teeth.

"Prongs," Sirius's face screws up in what you're sure is a mix of embarrassment and confusion at his friend's behavior, but perhaps there's a slight possibility of fear there, too. Fear that James has become a cannibal and the boy with the bed next to his will suffer tonight.

"That's good." James retracts his bite as quickly as he'd dished it out, smacking his lips like there'd been something swallowed and enjoyed, "That's good arm."

"You're a freak." Remus drawls, finally taking the tart from your spoon and letting the flavors wash over his tongue, "Pads and I are supposed to be the biters. Deer are just supposed to run away from everything."

"That's not true." James defends his animagus with a passion while Sirius snickers across the table, "Deer fight with their antlers. Sometimes deer fight so hard that their antlers come off. And deer do bite sometimes, thank you very much."

"Only during mating season." Sirius references the copious research they'd each done into their animal counterparts, "Don't steal another page from the dog book and start humping her leg, Prongs."

"It is not my mating season!" James exclaims, just a bit too loud for the social setting you're in. Your cheeks are blazing but thankfully James is making a fool of himself enough that no one is studying you. "I'm simply overcome with the urge to sink my teeth into people when I'm feeling particularly fond of them. Y/N's making sure Moony's stomach isn't flatter than his ribcage, and I appreciate that. Only a good woman shares her blueberry tart. Hence," He grins, more of a baring of his teeth than a smile, "I bite."

He leans down to take a chunk out of your shoulder this time, and you feel the sharp-but-gentle pricking of his teeth even through three layers of clothing.

You have the time and the power to raise your shoulder and clock James in the teeth with your bone. But you refrain, and perhaps that's why Sirius finally latches onto you instead of James.

"Careful, darling." He warns, his own canines glinting in the candlelight above, "Deer can go rabid. I'd make sure you're not contaminated with his saliva if I were you."

"Too late." James grumbles around the meat of your shoulder, raising his head quicker than you can react to lick a fat, wet stripe across your face, "I'm not rabid, Pads. But I can see why you dogs do the licking thing. It's not bad."

"Yes it is." You decide, smearing away his sticky spit with the sleeve of your button-up, feeling the phantom sensation of his teeth on your skin, "And if you do it again I'll bite you back."

"Kinky, you two." Sirius kicks you beneath the table, a wicked grin on his face, "Remus, I think we should take our meal elsewhere. Prongs and Y/N are about to start necking right in front of the pastries, and that's not the glaze I prefer on my donuts."
