Looking forward to talking today about some new ways of looking at what human lectins do. #FallACS2025

We are so grateful for resources to help us test key ideas about glycans and #Alzheimers disease. #glycotime🧪

To overcome challenges that #neurodegenerative diseases pose, MIT’s Aging Brain Initiative has awarded seed grants for 5 innovative research projects. Congrats to Drs. Joseph Coughlin, Giovanni Traverso, Pattie Maes, Bin Zhang, @laurakiessling.bsky.social & @eboyden3.bsky.social ! bit.ly/4mVasaV

Lead author @ssmelyansky.bsky.social spearheaded a strategy to label a single sulfur-containing glycan called ManLAM on the cell envelope of the bacteria that cause #TB. news.mit.edu/2025/new-mol... or here: www.pnas.org/doi/10.1073/... 🧪 #glycotime @mitchemistry.bsky.social

We are so excited to see the cool science that will come out of your group #chemsky

ACTION ITEM-----ACTION ITEM Implementation of Schedule F This is what a lot of us have been worried about. This allows for many civil service positions to replaced with political appointees. This could include NIH institute directors and even POs. BUT THERE IS A COMMENT PERIOD... 1/n

🙏 We need your help 🙏 The government continues to cancel grants at both NIH and NSF to censor science it doesn't like. We're tracking terminations to organize and advocate. Please report your terminated grants: NIH: forms.gle/J2znQ7y7YpeP... NSF: airtable.com/appGKlSVeXni... w/ @noamross.net

We’re thrilled to feature an incredible lineup of plenary speakers at #Glyco27! These experts will share cutting-edge insights and the latest advancements in glycomics across areas of health, including immunology, neuroscience and more! Register today: glyco27.org/en/begin @glycotime.bsky.social

These kinds of cuts are taking place when #TB rates are rising, including in the US. They dovetail with USAID cuts to #TB programs.

Job opportunity in SF to work at a small startup with the first PhD graduate of the Lieberman Lab!

A new means of selectively imaging the inner mycolate of mycobacteria using a compound that covalently modifies an enzyme intercepts to create a new intermediate with the Kim lab, @thebrysonlab.bsky.social and the Bernhardt lab. #TB

Thanks to Ratmir Derda we have an articulate reply to: www.science.org/doi/10.1126/... putting glycans back into the picture! @laurakiessling.bsky.social @anneimb.bsky.social @carolynbertozzi.bskyverified.social @molinarotony.bsky.social @dbojar.bsky.social @siglecdude.bsky.social

This is really beautiful research showing how the glycocalyx changes with aging and its impact on the blood-brain barrier.

For the Idaho Statesman 🥔, Professor Melanie Samuel explains how science funding drives cures for diseases like Alzheimer’s and cancer— and the devastating impact of mass firings in Health & Human Services. Happy Homecoming 🧪🧬🔬🏠 www.idahostatesman.com/opinion/read...

Make sure you, your trainees, and anyone else who might listen to you understands what "indirects" actually are, how they are established, and what Universities contribute. H/T @rodallab.bsky.social Please share widely! www.youtube.com/watch?v=yxTD...

Cells are filled with toxic stuff that damages healthy proteins. Is that garbage just left to rot on the curb? No way! Ubiquitin ligases have evolved to recognize chemical damage and clean it up! www.nature.com/articles/s41...

Thinking about the cool #chemistry all those understudied bacterial species do

Just listened to a fantastic talk on harnessing evolution to do new #chemistry by @francesarnold.bsky.social at the Bowei Research Conference in Taiwan. Loved her advice: “Nature does not care about your calculations.”

Really enjoyed the opportunity to have the @kiesslinglab.bsky.social collaborate with the Imperiali Group on exploring human lectin interactions with glycans. #glycotime Some initial findings are here: www.biorxiv.org/content/10.1...

Helpful time-saving advice

Happy Saturday. If you're working on your NIH specific Aims for a February submission, don't include a figure. grants.nih.gov/grants-proce....

HAPPY HOLIDAYS and EXCITING NEWS!!! We are offering two conference scholarships for 2025 to early career scientists! One for the Keystone Proximity-Based Therapeutics Conference and one to Frankfurt Conference on Quality Control in Life Processes. Application and details: forms.gle/aP4n7HTujetb...

@kiesslinglab.bsky.social is fortunate to have Gerard Porter as a member of our team @mitchemistry.bsky.social. I loved this article highlighting how the Caribbean Science Foundation is facilitating the education of talented researchers to promote innovation www.eecs.mit.edu/a-launching-...

This topic (and conclusion) is one that I have been teaching about for awhile in my organic chemistry class. The difference is that it was not within reach 10-15 years ago. This analysis is valuable for teaching. #chemsky 🧪

Cool work from the Traverso group @mitofficial.bsky.social news.mit.edu/2024/bioinsp...

Valerie Lensch of @kiesslinglab.bsky.social and the Johnson group reviewed different glycan-based strategies for eliciting an immune response: academic.oup.com/glycob/artic... #glycotime

When I went to the @yaleuniversity.bsky.social #chembio retreat, I got this cool #glycotime shirt. I showed it to Yale alum @ssmelyansky.bsky.social. The response: “That’s so cool that they used the B. subtilis glycocalyx!” Wow. People in @kiesslinglab.bsky.social recognize cells via their glycans.

If you are interested or working in #structuralbiology, as you see any protein (yes, *any*), you should be thinking: is it glycosylated? The answer is likely to be yes! You can predict N-glycosylation sites and rebuild all types of glycans with ReGlyco glycoshape.org 😌 Check out the example ⬇️ 1/2

Looking forward to honoring David Gin tomorrow at the #chemicalbiology symposium in his honor. He was an excellent organic chemist who contributed to our understanding of #naturalproduct #vaccine adjuvants. We lost him way too soon.
