General overview of ammonia production pathways and the analysis the authors carried out on them.

If you study chemistry (or anything related), you'll hear repeatedly that an "easy" ticket to Fame-and-Fortune is to improve the energy-intensive Haber-Bosch process somehow.
It's a long road, but people are trying. 🧪

The surfing musicians work on the phenomenally.

At some point, I'll be able to get people to understand that, simultaneously, 100,000 years is a long time environmentally, and isn't that long evolutionarily (esp. for longer-lived metazoans).

It's hidden signaling for those who can spot them.

I'm seriously considering not taking on any future review of any manuscript with "hydrocarbon migration" or "reservoir potential" in the title. It's not so much ideological; it's mostly because those that get to me tend to be data-poor, boring, and derivative.

Global distribution and temporal coverage of DO profiles. (a) Changes in the number of profiles from major data sourcesduring 1950–2024. (b–c) Spatial distribution of decadal-mean profile counts for 1960–1980 and 2000–2020, computed on a 1°× 1°grid, showing a transition from predominantly Northern Hemisphere sampling to much denser coverage in the SouthernHemisphere. The color bar indicates the decadal-mean number of profiles per grid cell (log scale).100

A new database to open the week with. One of the things that worries some of us about climate change is the loss of oxygen in the ocean. This database tracks long-term dissolved oxygen globally, and seems a handy tool study how things have changed. 🧪🌊

That's a partner to keep.
This wasn't about writing, mostly head-clearing.

Next time you're around, say, and we can try to organize a weekend trip. I promise I'll go on endlessly about what each rock is no more than a quarter of the time (unless asked specifically to explain something).

So, yes, back from a much needed reteat. A few days (mostly) free of internet and Dyoma. Long walks in the desert, a few sessions of play, and a lot of good food were a much needed reprive and recharge.

Brought all of you some 📷.

Why are some marginal seas sources of atmospheric CO2? Ocean-dominated margins(OceMar) featured with dynamic exchange with open oceanCO2 fluxes in OceMars largely ruled by external CO2 from the adjacent open ocean

It's a combined effect of temprature, strtification and primary productivity. Some regions of the oceans are outgassing as well.
Here is a link to a paper on why some regions outgas, and some take in CO2.

Yes. There used to be a small sink in winter with most of the outgassing in summer, but now it seems to be a year-round thing.

It's a rather topical list, mostly because undergraduate classes here skip straight to the major, and in my track, you couldn't get credits (back then, it has since changed) for classes we couldn't justify as topical.

Nevermind the jobs you had, tell me five classes you took in uni:
- Mapping
- The Origins of People and the Beginning of Human Civilization
- Geomorphology & Geology of Mars & Venus
- Physics of Failure in Rocks and Granular Materials
- Chemical Oceanography

Conceptual illustration of liquifying metamaterial for a fluid-like applications. (A) Metamaterial in a standard lattice structure (left) and metamaterial unit cells submerged in a liquid (right). (B) An example of an application of metafluid in a thermodynamic cycle, where motion, compression, and expansion of the unit cells are needed. (C) Illustration of the proposed concept for metafluid, which is based on time-varying magnetic fields to manipulate the unit cells including motion, compression and expansion, for (C1) a 1D lattice and (C2) a conceptual illustration of a honeycomb 1D lattice to allow a greater capacity.

Back to our regularly scheduled edutainment:
We can get metamaterials to do stuff that normal materials won't. These materials are usually solid, but recently, there were some mechanical metafluids created, and they can be controlled magnetically. 🧪

No more posts this week (not going to be a #WeekendReading as well), taking an internet break for the weekend.
Service will resume on Sunday (assuming working internet and no war).

פערים סוציו-אקונומים מאוד גדולים בתוך אוכלוסיית התלמידים שהובילו בעבר למקרי אלימות. אם יש לכם את האפשרות, זכרון יוסף או נופים הרבה יותר מוצלחים (למרות שעל נופים יש הרבה מאוד לחץ)

The mean seasonal CO2 flux [mmol m−2 day−1] of the Eastern Mediterranean ultra-oligotrophic sub-basins (located South of Crete), estimated through thermodynamic calculations [pCO2 (sw) and SST relationship, using the mean seasonal SST and salinity data (MedATLAS) and wind data (MedGloss coastal stations). The more red it is, the more CO2 is being released into the atmosphere.

And since someone's going to ask, this is the first paper we put out on this, almost a decade ago now. Probably about time to revisit the topic.

Time series of the computed daily air-sea CO2 flux. Negative values indicate ocean absorption and positive values indicate ocean emission. Blue dots with orange error bars indicate the flux obtained with the observed data; blue dots with blue error bars indicate the flux obtained using interpolated data. Red triangles indicate days with wind speed above 8 m/s. The inset panel show the evolution of the monthly fluxes with the corresponding error. The lower panel shows the time series of the daily averaged wind speed values.

A few years back, we showed that the Eastern Mediterranean, mostly due to warming and oligotrophication, is becoming a source of CO2 to the atmosphere. With marine heat waves, this trend might be now creeping to the Central Med. 🧪🌊

I liked enough of Lower Decks to enjoy it, but it never made me laugh. I mostly enjoyed the minutiae and granularity that the show could go into because it was a comedy.
SFA is still in the "let's see if it can pick up" phase for me, but it would help if they picked what kind of show it is.

There is a lot of Lower Decks DNA in there, a lot of little Easter Eggs. It feels like it is being held back from being the high school comedy it really wants to be.

Baseline behaviors. Bars represent the proportion of participants who engaged in each behavior, grouped by lifestyle and advocacy actions in the control condition (n = 1,739). Error bars represent 95% CIs.

Annoying question: How do you make people take part in collective action on climate change?
This study points to two main things: it needs to feel like it's achieving something (effective), and it needs to make people feel good about themselves doing it. 🧪

And... I gave up on it, one infodump too many. The pace wasn't my jam. Lots of really detailed #WorldBuilding, but the point to view bounced around a bit too much and while the plot seems like it was starting, it was moving a bit too slow for me.

That's an excellent stage name

I know, thermodynamically, I should be up and about and properly awake, but the kinetics just isn't there.

Different language families, it just happens they sound similar. There is also a third one, as Yuri (百合) and Yūri (悠里) are also names in Japanese with their own meaning.

Some aspects of the intensity of PTSD relate to how the trauma is experienced. Sensory modulation can play a role, esp. when it comes to experiencing missile attacks. High sensory responsiveness seems to relate, in these, to trauma-related symptoms and hyperarousal. 🧪

YouTube video by Storied Why A.I. Struggles with Negative Words | Otherwords

Otherwords with @ericabrozovsky.bsky.social on PBS has a nice take on negation (with a side note on why LLMs are really bad with it), which I think will not be uninteresting for us in the English-second-language crowd as well.

Was not actually aware of it, but make sense, comparing and contrasting with how many names in Arabic relate to the 99 Names.

As far as I know, Yuri is derived from Georgios (which means earth-worker, as it turns out).
