Bracher Lab

The Bracher Group in the Department of Chemistry at Saint Louis University. Researching chemical evolution and the origins of life on Earth and other worlds.

Very excited to get started on this new project!

Thank you for your support, @RCSA1 and @HSFdn !

[Research Corporation for Science Advancement @RCSA1]

Congratulations to Paul Bracher @ChemBarkPaul @BracherLab @SLUChemDept @SLU_Official and Christopher Hamilton @UArizonaLPL @uarizona for “Rocky Roads: Flow Pathways and Chemical Evolution in Vesicular Lava and Pumice.”

Congrats to Hayden and Kevin M. for graduating @SLUChemDept today with their B.S. degrees. Good luck in grad school!

[Bracher Lab @BracherLab]

On Friday, we celebrated Kevin’s successful M.S. defense. Graduation is right around the corner. Congrats!

@RosieRedfield Sure! Here’s one from this week on how cationic depsipeptides (copolymers of hydroxy and amino acids of possible prebiotic importance) and RNA can stabilize each other. It’s also open access. https://t.co/3Yh1BhxBDm

[Bracher Lab @BracherLab]

@RosieRedfield We do not work with organisms, but prebiotic chemistry certainly falls within the realm of astrobiology. You should check out #AbSciCon next year!

[Bracher Lab @BracherLab]

@RosieRedfield Ok, I’ll play. We are organic chemists who study reactions that might have been important on Prebiotic Earth. Here’s a paper we published last year. https://t.co/NALhoqPNCh

Check out our paper on origin-of-life chemistry published today in @NatureComms, “Prebiotic condensation through wet–dry cycling regulated by deliquescence”. It’s a collaboration among us, @DrJayTweets, and @4ChemEvolution. #NSFfunded Free access: https://t.co/ugqgddsZBv. (1/7)

[Chemical Evolution @4ChemEvolution]

The #evolution of a single #biopolymer gets much attention, but co-evolution might have been the thing! New data shows how RNA and proto-peptides stabilize each other! https://t.co/gwunwkTJns @NSF #NSFfunded @GTSciences @scrippsresearch #RNAworld @NASAAstrobio

Big plans for improving our Twitter content and finally updating the group website this summer. Here’s our most recent group photo (adhering to all COVID-19 guidelines)!

Christine is the best! It has been an absolute privilege for all of us at SLU to work with her and the Center for the past three years. We'll be following @GaTechEnergy and looking for any excuse possible to visit Atlanta.

[Chemical Evolution @4ChemEvolution]

So excited to share that our Managing Dir is taking a new role @GaTechEnergy. She will be sorely missed at CCE where her encouragement, logistical prowess & positivity have made such a huge impact. Thanks for everything, Christine! https://t.co/IKd4VUSPfq @GT_Sciences @GT_CHEM

Also, we have an immediate opening for a postdoc to work on the origin of life on organic worlds, like Saturn’s moon Titan. Interested candidates with experience in organic synthesis and NMR/IR/MS should contact Paul ASAP at [email protected]. #chemjobs @chemjobber (7/7)

We can’t think of another organic reaction where increasing the humidity of the room from 30 %RH to 50% RH has no effect, but increasing the humidity from 50 %RH to 70 %RH results in a ten-fold improvement in yield. (6/7)

Really nice look at Cairns-Smith's theory https://t.co/LQqlvbw3Hy

Congrats to Thomas Campbell (@BracherLab ) and Anna Priddy (Lewis Lab) on their wins at the @SigmaXiSociety research symposium!
