Awesome, thank you! I have added you as a moderator.
Amazing!!
AAAHHHH 😭 Such a relief. This was stressful.
The websites makes use of Contabo's object storage service for storing and serving images. Earlier during the month, I got an e-mail saying that there would be a 12-hour downtime window due to a migration. Alright, no problem.
A bit before this users reported problems with uploads. I figured this was related to the migration.
After the "migration", images still caused problems due to some "administrative rule" preventing uploads. I sent messages daily to Contabo. At first they were responding that "their engineers were looking into it, that this was related to the migration, and that they had no time estimate". OK, I can be patient....
After a few days I lost some of my patience and pressed them more often, until they started sending me generic messages and eventually saying that "the problems were already fixed" and suggesting it may be some configuration error on my side.
This is where it got stressful, because my knowledge of the implementation of the images back-end is superficial. So... That meant I would need to study the details and either fix it myself or show proof that it was their fault.
These past few days I have tried to do some reading and tested configuration changes, but I am the kind of person that puts too much on their plate and I have been quite busy, so this has been an additional stress point.
Today, images suddenly started working (until it came down again due to some logs piling up). This tells me that it was not a configuration issue and it was with high probability something on Contabo's side that they fixed today. Uploads are working as well now. Contabo support never shared any information about the specifics of what went wrong, so I don't know.
This doesn't mean that I don't need to study the details, but at least now the pressure is lower. My plan now is to do some studying on how images are stored and served and once I have a good understanding I can migrate the instance to a dedicated server. I will also look into techniques for making a server more resilient when things do go wrong.
Yes, it is pretty frustrating.
I keep sending them messages every day. Today's reply:
This is connected to the migration and there is no ETA currently.
Not very happy with them. I am looking into how to move the images somewhere else.
Thanks! <3 Cost is not the issue. The reason why I selected this option was because it seemed a good choice at the time. Moving the image database around is a bit of a hassle so I chose to just keep it as it was even after learning of other options. Last time it took several days of downtime to move the images over because the transfer speed into/out of the object storage is very low.
If I would have known that this would happen now, I might have taken this opportunity to move all the images over. But I was not expecting this amount of downtime. Now I worry that trying to move images from one place to another when the object storage is acting up is risky, and also I am busy.
I sent another message to support this morning and received:
We are sorry for the inconvenience caused. Please note that our technicians are working diligently on this matter, there is no ETA.
Sorry 😓
They are cheap. But I think that at the current total cost I would be able to improve performance while keeping cost about the same by migrating the instance to a dedicated server instead of a VPS + object storage.
Only that I am frustrated at the object storage provider (Contabo), and now I see why their reputation is not great. Their reply was that they sent a warning about the "12 hour downtime during March 10th".... but obviously these effects have extended both to before and after this "12 hour downtime". At least I got confirmation that this problem is due to their migration.
I contacted support this morning as the issue persists. They confirmed that it is related to their migration, but they have not been able to give me a specific time for when it will be resolved.
A travelling-wave strategy for plant–fungal trade
Abstract
For nearly 450 million years, mycorrhizal fungi have constructed networks to collect and trade nutrient resources with plant roots1,2. Owing to their dependence on host-derived carbon, these fungi face conflicting trade-offs in building networks that balance construction costs against geographical coverage and long-distance resource transport to and from roots3. How they navigate these design challenges is unclear4. Here, to monitor the construction of living trade networks, we built a custom-designed robot for high-throughput time-lapse imaging that could track over 500,000 fungal nodes simultaneously. We then measured around 100,000 cytoplasmic flow trajectories inside the networks. We found that mycorrhizal fungi build networks as self-regulating travelling waves—pulses of growing tips pull an expanding wave of nutrient-absorbing mycelium, the density of which is self-regulated by fusion. This design offers a solution to conflicting trade demands because relatively
High Fidelity Waveguides Through Vitreous Media Recomposition for Next Generation Photonic Devices
Abstract
A newly designed optical aluminosilicate glass that supports femotsecond laser written ultra-low loss optical waveguides is presented in this paper. Propagation losses as low as −0.020 ± 0.003 and −0.037 ± 0.003 dB cm−1 at 1310 and 1550 nm, respectively, are enabled by engineering the glass composition. Raman, Brillouin and electron microscopies are used to understand the origins of femtosecond laser-induced refractive index changes.
Molecules-mediated bidirectional interactions between microbes and human cells
Abstract
Complex molecules-mediated interactions, which are based on the bidirectional information exchange between microbes and human cells, enable the defense against diseases and health maintenance. Recently, diverse single-direction interactions based on active metabolites, immunity factors, and quorum sensing signals have largely been summarized separately. In this review, according to a simplified timeline, we proposed the framework of Molecules-mediated Bidirectional Interactions (MBI) between microbe and humans to decipher and understand their intricate interactions systematically. About the microbe-derived interactions, we summarized various molecules, such as short-chain fatty acids, bile acids, tryptophan catabolites, and quorum sensing molecules, and their corresponding human receptors. Concerning the human-derived interactions, we reviewed the effect of human molecules, including hormones, cytokines, and other circulatory metabolites on microbial characteristics an
Lost in the Amazon: Rediscovery of the Rio Santa Rosa Mushroomtongue Salamander (Caudata: Plethondontidae) from Ayacucho, Peru | Zootaxa
Abstract
Bolitoglossa digitigrada Wake, Brame and Thomas, 1982 was described from a few kilometers upstream from the Rio Santa Rosa, Ayacucho Region, Peru, at 1000 m a.s.l. in the Eastern Amazonian Montane Forest. Besides the type specimens, no additional collections or sightings of B. digitigrada had been reported for 43 years, and there is no information about its phylogenetic position inside its group. During a field expedition conducted in October 2022, we found four individuals of B. digitigrada in a corn and banana field near the community of San Jose, approximately 2.7 km from the type locality. Here, we provide information about living specimens, update description of coloration in life, elevation, and evaluate the phylogenetic relationships of B. digitigrada with a molecular phylogeny based on a 16S rRNA sequence.
Issue with images expected during a 12 hour period today
The server's images are stored and served using object storage.
The object storage provider has sent a message stating that they will perform a 12-hour migration tomorrow, March 10th, from 8:00 AM – 8:00 PM CET, so downtime of the object storage service is expected. Site images will likely not be displayed during this time.
In these past days users have reported issues with image uploads. I suspect that the issue is related to this same migration. If so, images should be back and the upload issue resolved by tomorrow night. If uploads are still causing problems I will investigate further.
I think it is the object storage provider... I see that there is a scheduled migration for 12 hours March 10th, but I suspect that they may have already started moving things around.
Thanks. I have not changed anything recently. I am also blocked from uploading. Not sure yet what the problem is, I am looking into it.
I think the difference in time is too big. Also, in the talk page's archive it is stated that the wikipedia was updated because of this meme, and not the other way around. This is from the talk page:
Looking through the archived history of the talk page, I can confirm that the claim on the wiki page is derived from the viral post, and not the other way around: https://en.wikipedia.org/wiki/Talk:Gulf_of_Mexico/Archive_3#Chalchiuhtlicueyecatl
How did I miss that?!
My timeline is incorrect then. Since the post from sassymetischick.bsky predates the wiki edit, it is more likely that the wiki edit was made in response to this meme, and not the other way around. This pretty invalidates what I said above...
I still can't find any evidence of this being an actual trend, but I no longer have a good guess about the origin.
I have banned multiple of those accounts for DM spam. Banned a new one just now.
I'm not sure this is a bot. I suspect it might be a real person who doesn’t realize how they're coming across. Initially, I thought it might be a strategy to get attention, but if that were the case, I’d be surprised by their persistence with a strategy that isn’t very effective.
I suppose it is kind of effective if we are making posts about them... Hmm...
I prefer not making too many assumptions other than to assume no malice. But of course the DM spam will not be tolerated.
They have gone from:
Unlike other companies, we don’t sell access to your data. .... Nope. Never have, never will. And we protect you from many of the advertisers who do. Firefox products are designed to protect your privacy. That’s a promise.
To (paraphrasing) "Ahh, well, we don't have ownership, we just have a nonexclusive, royalty-free, worldwide license for the purpose of doing as you request with the content. We can also process your data as we describe in the Firefox Privacy Policy.... Ah, and, of course, we may change the policy in any way we want and you automatically agree with it by continuing using the service".
In the past, they used language that included very specific limits on how the data could be used. Now, they make no promises and obfuscate the possibilities by providing 'examples' of ways that the data might be used.
If they were serious about privacy, the minimum would be to be transparent and specific about the data use. The lack of specificity makes it abundantly clear that they intend to use the data in ways that users would disapprove.

Yes, but that version is in German. That website also has one in English: https://annas-archive.org/slow_download/24154814bfe1e676d79509c3db1f74a4/0/0

Woah, interesting. The author is José López Portillo. I thought he shared the name with a former Mexican president, but, nope, the author is a former Mexican president.
The title of the English version is a bit different, but the text appears to be the same. It is a novel, and I can find no mention of the gulf of Mexico or of Chalchiuhtlicueyecatl in this book. To me it looks like a mistake in the citation.
The claim appears to come from this text (citation 1): https://www.scribd.com/document/703207646/Dioses-prehispanicos-de-Mexico-mitos-y-deidades-del-panteon-Fernandez-Adela-1992-Mexico-D-F-Panorama-Editorial-9789683803061-cbee5
Unfortunately, that book does not contain references nor is it stated where this claim comes from.

Human Brain Organoids and the Mereological Fallacy
Sietske A.L. van Till and Eline M. Bunnik (2024) have recently expressed a concern about science miscommunication regarding human brain organoids. They worry that the mereological fallacy is often being committed when the possibility of brain organoid psychological capacities such as consciousness and intelligence are considered, especially by bioethicists discussing the moral status of human brain organoids. Focusing specifically on one psychological capacity, namely consciousness, this article begins with a brief introduction to van Till and Bunnik’s concern about the mereological fallacy as it relates to brain organoids. It is then shown that whether the mereological fallacy is being committed depends on commitments in philosophy of mind about how consciousness relates to the brain and its neural mechanisms. This is demonstrated by appealing to two different example views about the ontology of consciousness embraced by J.J.C. Smart’s type identity theory and a version of hylomorphi
Individual and additive effects of vitamin D, omega-3 and exercise on DNA methylation clocks of biological aging in older adults from the DO-HEALTH trial | Nature Aging
Abstract
While observational studies and small pilot trials suggest that vitamin D, omega-3 and exercise may slow biological aging, larger clinical trials testing these treatments individually or in combination are lacking. Here, we report the results of a post hoc analysis among 777 participants of the DO-HEALTH trial on the effect of vitamin D (2,000 IU per day) and/or omega-3 (1 g per day) and/or a home exercise program on four next-generation DNA methylation (DNAm) measures of biological aging (PhenoAge, GrimAge, GrimAge2 and DunedinPACE) over 3 years. Omega-3 alone slowed the DNAm clocks PhenoAge, GrimAge2 and DunedinPACE, and all three treatments had additive benefits on PhenoAge. Overall, from baseline to year 3, standardized effects ranged from 0.16 to 0.32 units (2.9–3.8 months). In summary, our trial indicates a small protective effect of omega-3 treatment on slowing biological aging over 3 years across several clocks, with an additive protective effect of omega-3, vi

Abstract
Cacao and chocolate production is a global industry worth around $133 billion. Full sun cultivation is a modern approach aimed at increasing yields. We evaluated six cacao clones (PS 1319, CCN 10, CCN 51, PH 16, SJ 02, and CP 49) grown under full sun conditions to assess their leaf physiology, leaf structure, yield, and yield components. Leaf physiology was measured through seven gas exchange parameters, while leaf structure was analyzed using eight measurements. For fruit and seed, we evaluated seven yield components. The clones showed differences in gas exchange. Clones PH 16 and PS 1319 had higher net photosynthetic rates per unit of leaf area (A), transpiration rates, and lower leaf internal CO2 concentrations. These A high values suggest the clones are well-acclimatized to full sun cultivation. Water availability, nutrient supply, and appropriate plant architecture also contributed to this acclimatization. Under high light intensity, the potential quantum yield of
Optical memory and counter using a graphene based hybrid plasmonic temporal integrator - Scientific Reports
Abstract
This paper presents design and analysis of an optical memory and counter based on ultra-compact temporal integrators (INTs) using a graphene hybrid plasmonic add-drop ring resonator (GHP-ADRR) and pulley-type ring resonator (GHP-PRR) for optical signal processing. Due to the valuable features of graphene hybrid plasmonic technology, the footprint of these INTs is equal to 4 × 3.5 µm2 for GHP-ADRR and 5.4 × 3.6 µm2 for GHP-PRR. Also, the performance of the INTs has been analyzed by the three-dimensional finite-difference time-domain method in the frequency and time domains, and the accuracy of the results has been compared with those of the math counterparts and also key specifications of the first-order temporal INTs including phase jump, insertion loss, 3 dB bandwidth, rise time, integration time window, and energy efficiency have been investigated. Based on the results, both circuits have better performance than the photonic counterparts. Furthermore, the performance

Abstract
We present ErAs:In(Al)GaAs-based terahertz transceiver modules, comprising transmitter and receiver components integrated on a single chip. The transceiver module is employed in a two-port single-path (TxRx-Rx) or 1.5-port pulsed free space photonic vector network analyzer setup, wherein the second receiver is an individual ErAs:InGaAs photoconductor. This configuration allows for simultaneous extraction of transmission and reflection coefficients or scattering parameters S21 and S11. The system achieves a peak dynamic range of ~59 dB for S21 and ~43 dB for S11 at a bandwidth reaching ~3.5 THz for the transmission and ~2.5 THz for the reflection path. These values are obtained by averaging over 500 traces at a scan rate of 4 Hz. The system exhibits superior frequency coverage compared to commercially available electronic vector network analyzers, thus offering a compact, cost-effec
Scalable temporal multiplexing of telecom photons via thin-film lithium niobate photonics | npj Quantum Information
Abstract
Efficient single-photon generation remains a big challenge in quantum photonics. A promising approach to overcome this challenge is to employ active multiplexing—repeating a nondeterministic photon pair generation process across orthogonal degrees of freedom and exploiting heralding to actively route the heralded photon to the desired single output mode via feedforward. The main barriers of multiplexing schemes, however, are minimizing resource requirements to allow scalability and the lack of availability of high-speed, low-loss switches. Here, we present an on-chip temporal multiplexing scheme utilizing thin-film lithium niobate (TFLN) photonics to effectively address these challenges. Our time-multiplexed source, operating at a rate of 62.2 MHz, enhances single-photon probability by a factor of 3.37 ± 0.05 without introducing additional multi-photon noise. This demonstration highlights the feasibility and potential of TFLN photonics for large-scale complex quantum infor
