Transient sensations of impending loss of consciousness: the "blip" syndrome
I have experienced these 'blips' in the past and was deeply troubled by them, as I thought that they could indicate something serious going on. While I don't suggest anyone to disregard any symptom that they consider to be potentially serious (read as: consult your doctor if you suspect something could be wrong), I have noticed throughout my life many different types of 'glitches' such as this one that turn out to be benign and common. To me, learning about these effects is a form of applied psychology in the sense that understanding that these feelings are normal and usually benign can help prevent health anxiety.

My immediate suspicion when reading the title was that this would be a temporary effect, with the fungi providing a buffer by storing the mercury but eventually releasing the more toxic organic forms. But it turns out that they do transform the organic mercury form (at least methyl mercury) into the less toxic and volatile elemental mercury!

I had not learned about the mercury demethylation pathways before, and as far as I can tell (2021 review) the research on it is still relatively new, with many unknowns. Very cool stuff, thanks for sharing.



So, you experienced it during the first videos you watched but developed a tolerance as you kept watching them?


Interesting! Flakey pastry sounds do nothing for me, but they are indeed very characteristic.


Yes, I believe so. It’s not so smart. And it’s just a forum, not even a paid service like a streaming site.


A while ago on Reddit I replied to someone in /r/The_Donald and I got banned from a bunch of popular subreddits.

From caudata.org I was banned for using a VPN from a country different to the country that I put I was from when I registered. The following reason was given: Your country doesn’t match.


I sleep like a baby during thunderstorms, they are very relaxing.


Interesting! Can you do that on purpose, or it happens when you contract the muscles in just the right way by accident?


Have you experienced ASMR?
'[ASMR](https://en.wikipedia.org/wiki/ASMR)' - or 'Autonomous Sensory Meridian Response' exploded in popularity a few years ago as the ASMR youtube channels emerged. The YouTube videos do not trigger ASMR for me, unfortunately. However, it did bring the term to my attention, and when I read the wikipedia page something clicked - I finally had a term for a very strange sensation that I was never able to explain to others. For me, this ASMR response is not something that I can reproduce on purpose. But the times that it happens it usually occurs when someone else asks me something. For example, during middleschool I remember that sometimes a friend would stand next to me and ask me for a pencil. As I would retrieve the pencil, I would get into this dissociated-like state that was very peaceful and tingly, and I would not want it to stop. I would be very slow in retrieving the pencil and pretending I was still looking for it - and then I would ask some question to try to make the interaction longer because it felt so interesting. It still happens some times but is rare, and it occurs when I am busy in the office or the lab and someone comes and asks me something or for something while I am paying attention to something else. It is a very pleasurable state that is also very fragile - as if someone managed to scratch the perfect itchy spot in my brain for a moment. It is odd, and I think it fits the definition of ASMR perfectly. The only other way that I feel a similar effect but not as strong effect is when am getting a haircut the hairdraisser is cutting the hair in the back of my neck with the tiny trimmer. I am curious about other people's experience with this phenomenon, because I have not found many people that can relate to my experience. Have you felt this? Do you know what your triggers are? Do the YouTube videos do it for you?

Very cool. I understand part of it, but I will have to do some work to really get it.

Nature Communications has a transparent peer review process, and there was a nice discussion between authors and reviewers while trying to get this published - which is worth looking at if you are interested in the divided opinion during the peer-review process that the article mentions.

Paper (open access): https://www.nature.com/articles/s41467-022-33667-1

Peer-review file: https://static-content.springer.com/esm/art%3A10.1038%2Fs41467-022-33667-1/MediaObjects/41467_2022_33667_MOESM2_ESM.pdf


No. Many users never interact after approval, even if I approve right away.

I had issues while trying to setup the e-mail notifications and never got back to it, so new users won’t get notified when I do approve them. It is possible that some of them never return to check - that is one of my guesses. Is your instance configured to send the e-mail notification?


Crypto will always persist in some form, but the future of crypto as an institution—as something that might one day destabilize the big banks, or at least operate in parallel—has never been less certain.

I am optimistic on this. I like the technology, especially the more basic ‘digital cash’ crypto implementations, and I still think that crypto has a good chance of operating in parallel. The concept is revolutionary, and the technology is still going through the early phases of development. Decentralized exchanges and price stability will (hopefully) eventually arrive, and with that we will see an increase in adoption. Whether speculators win or lose money, or centralized exchanges turn out to be running sketchy operations, will cause ripples in the short term - but I don’t think that really changes the fundamental idea of private digital cash. The volatility at the moment makes it difficult for true adoption to really take off - users will often exchange fiat for crypto shortly before using it, or exchange crypto into fiat as soon as they receive it, in order to avoid the price fluctuations. But the hype and volatility can’t last forever… I think (or, I hope) that once the speculative hype cools off for a while and prices stabilize we will be able to see some progress.


Sex chromosomes are essentially supergenes run amok

I like that observation.

I was superficially familiar with the concept of a ‘selfish gene’, but I did not know of any specific examples. The segregation distortion (SD) gene in Drosophila is very interesting.


That’s tragic. In the case of Zhan at least it seems like the company is being transparent and accepting that this likely ocurred due to a malfunction. Let’s see what that means in terms of actually taking some responsibility for it.

As for the second case, it says:

The Tesla center in Nanjing said that the maximum speed reached 150 kilometers per hour during the accident, and the electric switch was stepped on with no brakes, while Jing stressed that he had been stepping on the brakes

I don’t know what the electric switch is. Is this the accelerator?

It is kind of scary that the tools used to determine whether the user or the manufacturer are responsible for an accident like this one are installed and analyzed by the manufacturer. Or is there a trusted third party mediating this?



I am thinking about those explanatory videos where they ask you to pause the video and try to find the answer yourself before continuing. I always pause and try - it is fun. But sometimes after several unsuccessful attempts I get frustrated and I just skip to the answer so that I can move on. It would be great to have this option with other things in life… I enjoy the process of learning via trial and error, but having an AGI next to me so that I can cheat a little bit from time to time would be great.


Just read some of the discussion over why this project was stopped.

the concerns of its usage by trolls has been far greater amongst the community.

It pains me, because at some level, I think it’s a useful and missing function, however it’s antithetical the values of the fediverse.

I am probably being dull, but I don’t get it. Why is having a search engine to search over the fediverse a bad thing? Why does that help trolls? And how is this antithetical to the values of the fediverse?




Thanks. I have installed it now


This finding implies that the female beauty premium observed when education is in-person is likely to be chiefly a consequence of discrimination. On the contrary, for male students, there was still a significant beauty premium even after the introduction of online teaching. The latter finding suggests that for males in particular, beauty can be a productivity-enhancing attribute.

The conclusion that they are drawing here is much, much stronger than what I think is reasonable to conclude from their methods and data. I do not agree that the results imply this - which gives me the impression that the ‘imply’ here means that the data conforms to their pre-conceived hypothesis. A hypothesis that might be slightly tainted by their unconscious sexist bias.


Current status of the PinePhone distros
Hello! I purchased a PinePhone UBPorts version when it was first available a while ago, but I didn't have the time to play with it then. I just turned it on and updated the Ubuntu Touch, and I am surprised that the most recent update in the Stable branch is from the end of 2020. I see that there have been [more recent releases](https://ubports.com/blog/ubports-news-1/post/ubuntu-touch-ota-23-release-3855) of Ubuntu Touch for other devices, but they do state the following: > The Pine64 PinePhone and PineTab are updated independently of the rest of these devices. The stable channel for the PinePhone and PineTab will not receive an update labeled "OTA-23". [This website](https://devices.ubuntu-touch.io/device/pinephone/) confirms that latest stable release of Ubuntu Touch for the PinePhone is from 2020. I couldn't find any statements on this, but I suppose that UBPorts is no longer interested in supporting the PinePhone - or atleast it is not one of their priorities. I am trying to figure out what to do with this phone now. The wiki has a wide selection of distros [here](https://wiki.pine64.org/wiki/PinePhone_Software_Releases), but doesn't give much info about them. Seems like it would take some effort to sift through each one of them. Do any of you use any of these and can recommend one? Is it even worth to invest the time to install one of these at the moment - or are all of the projects equally stale?

I am sharing this because I found it to be an interesting analysis.

Overall positive news, as this trial provides evidence that a single 25 mg dose of psilocybin can significantly reduce depression severity scores. During the trials an increase in suicidal ideation was also observed, showcasing that this form of therapy - while powerful and effective - is not a miracle cure that should be recommended without professional guidance.

How have you optimized your Pi-hole?
A few months ago I set up a Pi-hole at home. I tried to create a decent blacklist by first adding some regexes I found online and then doing some manual optimization by finding ads and blocking the ad requester through the queries page. But in the end it did not work so well. I still get a lot of YouTube ads, for example. So I still rely on uBlock for my ad-blocking. I just read that Chrome is planning to start weakening ad blocker plugins. I use Firefox, but it is still worrying that the space could potentially keep moving in this direction over time. So I am now more invested in learning how to have more control over my ad-blocking. Has any of you managed to optimize your Pi-hole to the point that it is possible to browse the internet without an ad-blocker? If so, how did you do it? Are there other good ad-blocking alternatives?

I put a drop of liquid from my lotus flower's vase under the microscope and noticed a lot of bdelloid rotifers, so I decided to record one at 400x magnification. I also used this opportunity to upload a video to a PeerTube instance. It is actually a bit of work to find an appropriate instance willing to register new users, as many of them accept a narrow range of topics and 'microscopy videos' is usually not one of them.

I have been making an effort to actually identify the contaminants that grow in my petri dishes. In this case the contaminants are those dark green spore islands. Looking at them under the microscope reveals that the spores of this species are produced at the tip of these finger-like structures. These spore-producing structures are called "[conidiophores](https://en.wikipedia.org/wiki/Conidium)". The presence of these structures is a characteristic of the phylum Ascomycota, within the fungi kingdom. ![](https://mander.xyz/pictrs/image/af69f6b5-47b6-490b-b5ff-46cd3ee6b4b3.jpeg) ![](https://mander.xyz/pictrs/image/be1f50ea-e39a-4031-af20-e964adcc8cb9.jpeg) Different groups of ascomycetes produce conidia with different morphologies. Looking through microscopic pictures I can see that this morphology of conidia is characteristic of the Penicillium genus. I am having trouble narrowing it down to the species level. Maybe P. digitatum or P. roqueforti, based on the macroscopic morphology and how common they are. But there are too many other options, so it is difficult for me to know for sure. If anyone around here is good with identification, please let me know.
