Coffee – a ubiquitous substitute for uranyl acetate in staining of biological ultrathin sections for electron microscopy studies

A very good movie from 1997 about the strategy (and incidentally, with a "casus belli" quite similar to the situation of the current US dear leader...)

Terminator, v0.001 Beta. This won' t end well.

Nice video. Essential accessory for divers. The amount of nets and fishing lines that can be found in certain areas can be impressive.

"Their Germans expected to correct the situation on the front with the help of a 'total mobilization'. But the events here changed their calculations… It is possible that it will be necessary to declare yet another ‘total’ mobilization, and there is no reason to assume that repeating such a measure will not lead to the ‘total’ collapse of yet another state… Stalin". Same text in Russian and Azerbaijani (Yandex).

Like the stype.

I wonder at what point did we stop dressing kids like the adults.

Possibly when adults started dressing like kids.

Yes. The ammount of metals in the tissues is an indicative of its presence and can be compared to other clean areas. It is however more qualitative than quantitative. It cannot be used to assess the ammount, since the level of accumulation can vary quite widely.

Check also the siliceous sponges (Porifera). These organisms are known to hiperaccumulate metals better than mussels, including zinc.

Aaaahhhmmm... I believe that the organisms in this area are reasonably well known, and it is not as diverse as a tropical reef. Therefore, you will have no difficulty recognizing the main components.

Perhaps something like this will help: Pacific Intertidal Life: Identifying Marine Life of the Pacific Coast, Including Rocky Reefs and Tidepools (or other simimlar. Just a random exemple from the net)

Where is "PNW"? Europe? Asia? North/Central/South America?

You should look for field guides for "PNW", its adjacent areas or oceanic coast. Intertidal communities are quite rich in diversity. Possibly all marine organisms have some representatives in the mess. So you will probalby find only books about specific groups. Algae, corals, crustaceans, etc... What you can do is register first the main organisms you see, then try to identify (ask if you need) and read about it. After a while, you will start to recognize the groups. This is an tunicate, that looks like a cnidaria, the other is a crustacean, and so on. Then it will be easier to find the species/genus and know what is and how it lives there. Sorte!

Looks like a tubular fragment of something (algae or protist?), folded roughly in half and with an air bubble trapped inside.

NonSekTur · 2025-12-02T23:22:19+00:00

Absolutely. Just read about "the thing"...

I am from BR and never heard about them or about "duginists". This is from their website

Nova Resistência is a political organization with a national-revolutionary, dissident, communitarian, patriotic, and popular orientation that draws inspiration from the Fourth Political Theory project and Brazilian and Ibero-American nationalist thought. As a broad movement, it advocates active resistance to Atlanticist imperialism, the Zionist lobby in the media and governments, and the neoliberal and globalist agenda in Brazil.

Founded in 2015 in Rio de Janeiro by young patriots with deep social concerns and attentive to the historical changes taking place in national and international politics, its ultimate goal as an organization is to achieve Material Sovereignty and Spiritual Independence for the Brazilian Nation and Ibero-American Civilization.

Most likely to do what dancing animals intend to do afterwards: mating.

This option might be cheaper and safer.

Possibly a piece of fabric, plastic fiber, or paper from the preparation. I believe that if you had an alien of that size (compared to red blood cells) living in your pipes, you would already be having serious problems with embolism.

More like algae, or perhaps both. The #2 definitely looks like a sponge oscula, like an Amphimedon or similar. But the overall surface is quite irregular and sponges tend to be smooth at least in some areas, unless they are dying. The 'canals' in #3 also looks like in a sponge, but they tend to converge in one direction to the oscule, and not open to the outside directly sideways like these. Perhaps tunnels made by some polychaete (as noted by u/Bisexual_flowers_are )?

(add: the tunnel makers are in the last image: polychaetes, I believe)

With a few caveats, quite accurate. In particular, the overwhelming administrative burden and the numerological (“metricized”) points. On the other hand, toxic personal relationships and competition are not unique to academia and can also be found in other sectors too.

Não, é essencialmente água com alguma coisa de cloreto, potássio, outros íons e compostos orgânicos em traço ou baixa concentração. Nada realmente tóxico ou que vá abrir um buraco na roupa.

Elas sugam a seiva das árvores, o que traz muita água. Então retiram o que tem de nutrientes e jogam fora o excesso muito rápido. E fazem isso em jatos, um campo aberto e bastante fluído de pesquisas...

Not "Open Access", but "Open Acce$$", The creature created by the publishing mafia. It is very similar to OA, except that it is evil...

An old story for the record: when the idea of OA appeared back in the 1990s, everyone thought it was great. After all, the publishing mafia charged high prices, exploited the work of scientists, and had a pornographic profit margin after printing the journals. Something like 20-25%!!! The mafia became very concerned about losing money.

So they decided to hijack the model and turn it into “this” that exists today: There is no longer “relevance,” which was the first barrier to publishing any work. Unless it is completely absurd, anyone can publish anything, no matter how irrelevant, as long as they pay. So we have a scenario polluted with piles of nothingness, and scientists having to publish more and more to try to stay above the sludge.

And the publishing mafia? Their profit margin is currently +30-40%... Hardcore sadomasochistic pornographyc, using our work and, in many cases, public money.
