This work started already pre-covid, which makes me even happier to see it finally in print. Thanks to @ayanezserrano.bsky.social for tremendous leadership in pushing it all the way through!

A rare bloom of Cosmo, CSU’s corpse plant, gave my group (Rose Rossell and @chemj.bsky.social) the chance to study corpse flower emissions in a fun collaboration with Tofwerk. Turns out to be an interesting, if stinky, story of pollination chemistry…
How a corpse plant makes its terrible smell − it has a strategy, and its female flowers do most of the work
When a corpse flower bloomed on campus, atmospheric scientists got to work. What they discovered provides new evidence about the unique pollination strategies of a very unusual flower.

I'm looking forward to EGU next week and seeing people - who will be there? If interested in Atmospheric Organics check out our oral session on Thursday and posters Friday morning (AS3.2). meetingorganizer.copernicus.org/EGU25/sessio...
You can also find Yumin and Flossie presenting on their work:

There is some "amazing stuff" in here on Climeworks and carbon capture / carbon offsets model more generally.
brief🧵 after the caveat that I have no idea if what is reported is true (but it mostly doesn't matter whether/if the numbers are off by >10x)
Climeworks’ capture fails to cover its own emissions
The carbon capture company Climeworks only captures a fraction of the CO2 it promises its machines can capture. The company is failing to carbon offset the emissions resulting from its operations – wh...

Oma kokemus: ChatGPT sanoi osaavansa kääntää MatLab-scriptin Igor-koodiksi. Generoi testipätkästä ihan kivannäköisen koodin. Tarkemmin tarkasteltuna siellä oli kuitenkin paljon virheitä. Jopa for-loopin syntaxi pielessä. R ja Python varmaan AI:lle helpompia, mutta kannattaa aina tarkistaa tulos.

My postdoc Jian Zhao did a great job in figuring out how to improve the performance of the vaporization inlet for aerosols (VIA). One of these days we need to do a direct comparison with the EESI-TOF to compare spectra and sensitivities for online detection of SOA.
Characterization of the Vaporization Inlet for Aerosols (VIA) for online measurements of particulate highly oxygenated organic molecules (HOMs)
Abstract. Particulate matter has major climate and health impacts, and it is therefore of utmost importance to be able to measure the composition of these particles to gain insights into their sources...

Can we, in real-time, deduce the ozone formation regime by measuring highly oxygenated organics (HOM)? In theory, yes. In a simple lab system, yes. In ambient air, we are still looking into it. In any case, since HOM were discovered, we have thought about these links, so was nice to now test it.
On the potential use of highly oxygenated organic molecules (HOMs) as indicators for ozone formation sensitivity
Abstract. Ozone (O3), an important and ubiquitous trace gas, protects lives from harmful solar ultraviolet (UV) radiation in the stratosphere but is toxic to living organisms in the troposphere. Addit...
