Photo from yesterday’s official opening of the new CryoMAS #ssNMR platform in #umea (Sweden). Great talks covering all aspects of #ssnmr and its diverse applications.

Actually Open AI (the parent company) is a non profit, with the mission to prevent the scenario you (rightly!) fear. At least the development is open source and transparent. Just imagine a for profit was sitting on this code......

Scifider abolished their system where you could buy a certain number of "points", so you could "scale" your investment to your needs. Now it's all or nothing. So, if you are just looking for commercial sources of chemicals, I recommend to be kind to your blood pressure and not even look at their commercial rates :-)

For freely available online textbooks on a variety of courses, LibreTexts is a great resource, especially to begin exploring a subject.

libretexts.org/

They're mostly accessible to non-specialists and have many advanced features: libretexts.org/advanced.html

Examples:

Astronomy and Cosmology: phys.libretexts.org/Bookshelve

Physics: phys.libretexts.org/Bookshelve

Math: math.libretexts.org/Bookshelve

Biology: bio.libretexts.org/Bookshelves

Humanities: human.libretexts.org/Bookshelv

#introduction.

I'm a chemistry professor at UC Irvine that specializes in inorganic chem and electrochem.

My research focuses on #electrification of the chemical industry, #decarbonization, #carboncapture, and #sustainability. Current projects on electrochemical carbon capture and utilization, but also electric fields in #catalysis and #bioinsipred systems.

I'm an #academicmom that loves cooking, running, cycling, hiking, ultimate frisbee, and ice hockey but never has enough time.

Trying to link this long hoped for news from Eric Berger to the tag.
Welcome!

Looking for recommendations- books for a teenager with an aversion to love stories 

@Rachel
also and age appropriate: The Earthsea Books by Ursula K. LeGuin, especially the early ones (there is one love story in a later book)
also: The King's Peace and the King's Name by Jo Walton @Bluejo The hero there is . Not to confuse with the prequel "The price in the game", which is definitely a (very good) love story.
I also very much join in @Fanua 's recommendation of "A Wrinkle in Time"

Paper day! We wrote a paper on the JWST backgrounds, how they compare to predictions, and implications for science performance. arxiv.org/abs/2211.09890

Discerning astrophysicists like their deep fields like chocolate and coffee – as dark as possible. So, how dark is the JWST sky?

thread 1/n

How dark the sky: the JWST backgrounds

We describe the sources of stray light and thermal background that affect JWST observations; report actual backgrounds as measured from commissioning and early science observations; compare those background levels to pre-launch predictions; estimate the impact of the backgrounds on science performance; and explore how the backgrounds probe the achieved configuration of the deployed observatory. We find the observatory is limited by the irreducible astrophysical backgrounds, rather than scattered stray light and thermal self-emission, for all wavelengths $λ< 12.5$ micron, thus meeting the level 1 requirement. This result was not assured given the open architecture and thermal challenges of JWST, and is the result of meticulous attention to stray light and thermal issues in the design, construction, integration, and test phases. From background considerations alone, JWST will require less integration time in the near-infrared compared to a system that just met the stray light requirements; as such, JWST will be even more powerful than expected for deep imaging at 1--5 micron. In the mid-infrared, the measured thermal backgrounds closely match pre-launch predictions. The background near 10 micron is slightly higher than predicted before launch, but the impact on observations is mitigated by the excellent throughput of MIRI, such that instrument sensitivity will be as good as expected pre-launch. These measured background levels are fully compatible with JWST's science goals and the Cycle 1 science program currently underway.

I wonder whether any of the developers are aware how I feel every time they push the "Restart to Keep Using Firefox" message in my face while in the middle of working?! I want to support browser diversity but it's difficult to continue using a product that shows so little respect for their users.

I can understand if this were for a serious 0-day vulnerability or something but this is for every single update!

Just saying no to leaf blowers ✊

I may have to deploy the rake however 🤷‍♂️

Hi #ChemiVerse

I might come to regret this, but I've seen some journalists compiling lists of people on here & I thought it might be useful in the early days here to do something similar for the chemistry community (& those who interact with the chemistry community – you can define that quite liberally).

So, here is a Google Form that you can fill in if you wish: forms.gle/gF9MLUGMWs23EFix6

And it feeds into this Google Sheet: docs.google.com/spreadsheets/d

(The form does not collect e-mail addresses)
