@mem_somerville_kbin What a wonderful initiative! And how great that it's available in a free format :)

Subscribed! Cheers. I'm a science teacher, I love this sort of thing!

Nessussus, in What Microplastics Might Be Doing to Our Intestines

@Girlparts Can somebody get the the original paper and report on what concentration they were using. Whenever I've compared lab results with environmental measurements, the labs are using >1,000,000-fold higher concentrations of particles to get a response. It's never immediately obvious because the two kinds of studies typically use different units.

The other question I have is the particle size. Their largest particles in the study are 1µm. That's generally the smallest that I've been able to find reported in environmental measures. Either it's just not possible to detect unlabelled particles smaller than that (which as an analytical chemist, I doubt), or particles at that size range break down quite quickly do the exponentially increasing surface area/volume ratio. If anyone has links to papers that look that far down the size scale, I'd appreciate them.

However, García urged caution in assessing the paper's findings, saying it contains elements in its theoretical model that likely can't be tested observationally, at least in the near future.

That makes the whole thing rather pointless, doesn't it?

at least in the near future.

I don’t think so. It’s an interesting hypothesis that has been slung on the table to account for weird discrepancies between current models and observed reality. It suggests a paradigm shift. Suggesting ‘we’re thinking about this is in entirely the wrong way’ is an important part of the scientific process.

Yeah, but the hallmark of a useful scientific theory is that it makes testable predictions.

So you would argue that the Higgs Boson was a useful theoretical construct ahead of the building of CERN or that black holes weren't useful in theory until detected?

No. Even if the predictions couldn't be tested at the time there was a clear path to doing it. That's different. This is (in my very limited understanding) more like string theory.

HexTrace,

Some of Einstein's predictions weren't really testable when they were posited. "Not currently testable" doesn't mean they can't be improved upon to be testable, or provoke a shift in thinking that leads to other research pathways opening up. The whole field has been somewhat stagnant and searching for something that can compete with the Standard Model, so ideas like this that could prompt a breakthrough get visibility and traction for that reason alone.

ivy, in The expansion of the universe could be a mirage, new theoretical study suggests

so if I understood this article properly, this is proposing a model where the universe is not expanding but just exists infinitely. also this seems to neatly fit everything together eliminating dark matter and energy

if so, that's crazy! it would be really cool to see some research on this in the future and hopefully see some new developments because of it

If it used Meteor Attack or Static E, then it is indeed a mirage

They use gravitational waves and parallax as other sources of confirmation for expansion and I don't see those mentioned or accounted for but I'm just a guy who reads science books for layman, what do I know...

Sodis,

I also don't see, how this new model explains, that every galaxy but one moves away from us.

stevexley,

I think that they are saying that they aren't moving away from us, the redshift is caused by this mass change effect not movement or acceleration.

VoterFrog,

OT but any good science book recommendations?

lanbanger, in The expansion of the universe could be a mirage, new theoretical study suggests

I so dearly hope this is accurate. I've been against "dark energy", "dark matter", and "perpetually accelerating expansion" for years now. This has the potential to be a Michaelson-Morley moment, where the Ether was disproven by creating a universe that doesn't require it.

That's really odd, scientists successfully communicated the situation to me for decades. Maybe the article's author just didn't bother to listen and/or deliberately ignored the message -- just like the lobbyists who worked hard to bury the importance -- because that's how things always go.

You can lead the horse to water but you can't make it drink, and now here we all are.

DeweyOxberger, in Scientists discover critical factors that determine the survival of airborne viruses

Rising CO2 levels makes SARS-CoV-2 more likely to survive? Bleach vapors make it more likely to survive? Oh man, this is so ironic.
More house plants people. And get some ammonia while your out.

My $.02 summary: They're for sure being absorbed by different cells in just about every organ of the body. But because everyone has them it is hard to find a control group to study the real effects. However, cell inflammation could be happening in the intestines.

Thanks for bringing it to our attention. Discovery is difficult right now, advertising in places that are genuinely relevant is a real service.

ImplyingImplications, in Catch-22: Scientific communication failures linked to faster-rising seas

Scientists failed for decades to communicate the coming risks of rapid sea-level rise to policymakers and the public.

Have they? Or have the marketing and PR departments of oil and gas companies paid for endless propaganda and lobbying to prevent change?

Did scientists fail to communicate the link between cigarettes and lung cancer or was it the propaganda and lobbying of tobacco companies that convinced the government to not do anything about it for decades?

Kichae,

Scientists have this nasty habit of being honest about degrees of confidence, which leaves politicians enough room for mental gymnastics, and allows people with direct conflicts of interest to sound totally confident in their denials.

When confronted with two people, one saying "we could see global temperatures rise anywhere from half a degree C to 2.5 degrees C, and this could lead to sea levels rising 30 to 60 cm, and may increase the frequency and strengths of hurricanes, el ninos, and la ninas" and the other saying "I promise you, none of that will happen, they're just being alarmists. Also, those numbers seem awfully small to be concerned about anyway, don't they?", well...

I see this at work all of the time. I've had to change how I report stuff because I used to have conversations like

Management: "Hey, Kichae, we released an A/B test for a new update. Did it increase playtime?"

Me: "The model shows playtime increases of between 20s to 3 minutes per week."

Management: "Guess not!"

Now I strip the uncertainty ranges, and I focus on reporting for individual cohorts, so people can see that some players went from playing 3 minutes to 4 minutes, and some players went from playing 3 hours to 4 hours. It's resulted in a lot more work for me, but at the same time, people are less likely to write off meaningful results.

RyanHeffronPhoto, in Catch-22: Scientific communication failures linked to faster-rising seas

Seems like a ridiculous article. To attempt to put the blame for lack of action on climate change on science communicators for not expressing enough certainty is absurd. Policymakers have known damn well for decades the potential implications.. they are not ignoring climate action due to the uncertainty, but for all kinds of other political reasons.

My thoughts exactly. Seems like the authors don't want to confront the idea that policymakers simply don't give a fuck about the climate, so the explanation has to be that scientists failed to communicate.

I mean, it's The Hill. They might "lean left" in their bias, but they're basically a mouthpiece for congress. of course they're not going to say "we voted against climate protections and resilience because we're receiving massive donations from people that would be hurt by those changes." (or, in the case of Manchin, is in fact a part owner of an oil company.... one that just got it's pipeline project rammed through despite pushback...)

interolivary,
@interolivary@beehaw.org avatar

Oh I meant the original authors of the paper they reference, but it does apply to The Hill too probably

a_statistician,

@RyanHeffronPhoto Yeah, it seems like scientists could literally be setting themselves on fire trying to get peoples' attention and policymakers would not act. This isn't a scicomm issue, this is a political problem - politicians don't want to solve problems that will cause short-term pain for long-term (generational) gain. There's no motivation to solve problems that won't resolve before the next election cycle.
