A reposting of: https://scitechdaily.com/volcanoes-send-secret-signals-through-trees-and-nasa-satellites-can-see-them/
This is in part the work of Robert Bogue, with John Stix & Peter Douglas.
Diffuse CO2 emissions can permeate to the surface and can stimulate plant growth, preceding any deformation, heat, or other warnings of an impending eruption.
See: Bogue, R. R., et al.. (2023) G-Cubed: Volcanic diffuse volatile emissions tracked by plant responses detectable from space. https://doi.

‘We’re All Asgardians’ a talk on the origins of Eukaryotes (us) with implications for our present-day immune systems by Brett Baker, University of Texas, Austin. Dr. Baker inaugurated the EPS Wares Distinguished Public Lecture series.
Eukaryotic cells are most closely related to the 'Hod' branch of the Asgard branch of the Archaea.

An amazing talk by Max Lloyd of Penn State University. He used clumped isotopes to separate the effects of CO2 abundance, water availability, and temperature on plant stress. The plot shows the clumped signal in lignin from recent trees but he has analyzed samples from the last glacial maximum. An implication is that even in a high-CO2 world, water and heat stress reduce the ability of plants to produce biomass.

@jeridansky For a Thursday six list, I would put Nina Simone's 'Feeling Good' near the top!

Lew Ashwal of U. Witwatersrand died this week. Over decades, his scholarship helped shape modern thinking on magmatic processes and global crustal evolution (from Grant Bybee).
I remember Lew very patiently helping a young geochemist (myself) understand why mountains made of anorthosite were such a difficult and interesting problem to solve.

@geologymull An excellent photo of basaltic quench glass (tachylite). I've not seen tachylite in person... It does look like the rock is leaking tar.

Not only was #ammineite recently discovered, it's only been present for a short part of Earth history; it needs copper and guano in dry areas.

Well, they didn't make it to 10 years... And I didn't keep my original purchase receipt, so I can't make a warranty claim...

#Sanidine from the Fish Canyon Tuff is essential to understanding the pace of events in the #Cenozoic
High potassium, quickly erupted and cooled, and old enough to have accumulated sufficient 40Ar from radioactive decay. These crystals calibrate neutron flux for 40Ar/39Ar dating. The 28.2 Ma age of the FCT sanidine has been fine-tuned using #Milankovitch cycles of other ash beds in stable sedimentary basins.

@molly0xfff I tested positive for #COVID for the first time over the holidays too -and I know exactly where I picked it up -a hockey game at #BellCenter #Montreal. Flu like symptoms for a week and a half... Luckily boosted a week prior.

Jonathan O'Neil of the University of Ottawa telling the story of the Hadean mantle and crust from the few scraps of rocks left to us from that time. Short- and long-lived isotopic systems constrain the timing and processes of the Earth's first crust. The second keynote at the Geotop annual meeting, hosted at ÉTS.

A fascinating keynote talk by Mathilde Jutras (now at the University of Quebec at Rimouski) on ocean chemistry changes due to increased greenhouse gasses. The talk was at the annual meeting of Geotop, the Research Centre in Earth System Dynamics with members from a number of Quebec's research institutions.

Joshua Davies spoke today on linking the Central Atlantic magmatic province (CAMP) with the end of the Triassic extinction. Isotopes and trace elements suggest that it wasn't the lava directly but the cooked carbon-rich sediments that did the damage.
