I am really enjoying this one every year. Together with a great group of students we analyse subjects related to sustainability. E.g. academic travel. We even got a nice little publication out of that work: mr.copernicus.org/preprints/mr...

This year: carbon footprint of computation and AI.

Today, teaching again our sustainability course at @istaresearch.bsky.social, we discussed about the "addiction" of humanity to fossil fuels. The promise of carbon capture and storage ("we'll solve it later") is so convenient, and who cares today that it probably won't ever work ...?

This is exactly what scientists have been saying for years:

The Collapse of Confidence in Carbon Capture | OilPrice.com

Carbon Capture and Storage, once seen as a lifeline for the oil and gas industry, is facing mounting doubts as delays, high costs, and poor performance cast serious doubts on its future viability.

The specific labeling allows seeing very important functional arginines even in >100 kDa large proteins. In MAS #NMR, we probe Arg dynamics without size limits.
Special shoutout to Fede @iomichiamofede.bsky.social , a great scientist and our master of enzymes and NMR in solids and solution.

The specific pattern of 13C spins and deuteration allows connecting the two methyls to the backbone.
With this information and chemical-shift predictions many methyls can be assigned in a straightforward manner -- such as in our Tom70 receptor of mitochondria and a 134 kDa large dehydrogenase.

Methyl-TROSY NMR is powerful to probe interactions, dynamics and structure in large molecule, but a significant bottleneck is the assignment of NMR signals to individual methyls.
We leverage a new isotope labeling scheme and a tailored NMR experiment to connect methyls of Leu and Val (->pic).

Does this comparison take into account that electric vehicles are much heavier? And a lot of the gain may be eliminated by the fact that the cars that are bought get heavier over the years?

Great. It usually is an inspiring conference, indeed.

I hope you had nice runs there :-)

paulschanda.bsky.social @paulschanda.bsky.social · 29d

I'd kindly propose that at least those who are directly dependent on taxes (well, that's all of us...) simply stop supporting Amazon.
Quite easy to do.

paulschanda.bsky.social @paulschanda.bsky.social · 29d

The usual argument brought forward by Amazon users is along the lines of "fast/convenient".
But how convenient is it to be robbed? They don't pay fair taxes, offer terrible working conditions, undermine local business.
What exactly is convenient there?

paulschanda.bsky.social @paulschanda.bsky.social · 29d

Could we scientists please stop having anything to do with Amazon? Could we please stop shooting into our own foot?

Amazon massively avoids paying taxes (profit shifting, declaring losses...). We talk about hundreds of M€ (or more..) every year. This is tax money we could use for useful stuff.

Thanks for these thoughts and for all the work of reviewing preprints and making them public. I agree, author shall be notified!

I wonder if editors also look at these reviews. That may be useful, provided no nonsensical "reviews" are posted by competitors. Not sure if that happens; I guess not.

paulschanda.bsky.social @paulschanda.bsky.social · Sep 8

Check out these thoughts about reviewing preprints. I agree, a change in the culture and practices would be very welcome.

James Fraser @fraserlab.com · Sep 8

Why hasn't Preprint Peer Review caught on more?

I discovered a small, but simple reason - authors are missing out on the JOY of getting feedback because they aren't notified when feedback occurs.

more in thread below!

Thanks for these thoughts AND for all the reviews of preprints you and your lab are doing. This is great and I really support this.
Maybe a reason why not so many people write reviews of preprints is that doing a proper useful review of a paper is a lot of work -- usually takes me a full work day.
