[André O. Hudson, PhD @HudsonLabRIT]

I had a fantastic meeting with my colleague, Dr. Pritam Ganguly, from the @RITscience Science School of Chemistry and Materials Science, about a potential collaboration using computational chemistry to explore antimicrobial peptides as targets for antibiotic development.

As we talked, we revisited a JBC study on diaminopimelate decarboxylase, the enzyme that catalyzes the final step in lysine biosynthesis via the diaminopimelate (DAP) pathways, converting meso-diaminopimelate (m-DAP) into lysine that was published in JBC: https://t.co/UECBG4GL09

What makes this pathway particularly compelling is that m-DAP serves a dual role in Gram-negative bacteria. It is not only a precursor for lysine for protein synthesis, but also the key cross-linking amino acid in peptidoglycan.

That discussion immediately brought me back to a functional complementation experiment we conducted for the study with my former student, Mary Leeman, MD. We employed the E. coli lysA mutant, which is auxotrophic for lysine, meaning it cannot grow unless lysine is supplied in the media or the pathway is restored via a functional gene. We introduced the two LysA orthologs from Arabidopsis thaliana under an inducible system: expression is turned on with arabinose and repressed with glucose, using an empty vector as a control in the lysA mutant.

Early on, the results were baffling. We observed growth on lysine-free media in the presence of glucose, but no growth when arabinose was added, the exact opposite of what we expected. We repeated the experiments many times, remade media, checked plasmids, and questioned every variable possible.

I remember thinking about this day and night, and then it clicked one day driving home!

Under arabinose induction, the enzyme was highly expressed, rapidly converting m-DAP to lysine. While lysine was being produced, the cell was effectively depleted of m-DAP needed for peptidoglycan cross-linking, compromising the cell wall and preventing growth. Under glucose repression, however, expression was low but slightly leaky, just enough to produce lysine while still preserving sufficient m-DAP for cell wall biosynthesis. Growth, it turned out, depended not on maximizing enzyme expression, but on maintaining metabolic balance.

Moments like that capture the joy of science. What initially seems perplexing often reveals something deeper if you stay with it long enough. Sometimes the breakthrough comes not at the bench, but in reflection.

At the @RITtigers, @RITscience, we believe that science and discovery have their greatest impact when they are accessible and understood. That’s why we are excited to launch our new Science Communication Internship starting in Fall 2026.

Strong communication is an essential, yet often overlooked, step of the scientific method. After data are collected and conclusions are drawn, science still needs to be shared, discussed, and understood. Translating complex ideas into clear and engaging stories helps connect research with society, inform decision-making, and inspire the next generation of scientists.

This new paid internship supports COS scholars who are interested and passionate about science communication. Interns will work alongside communications professionals and gain experience observing and participating in the entire process, from identifying research stories and conducting interviews to writing, editing, and publishing content, including social media.

They will help develop research features and short articles, collaborate with faculty, student researchers, and staff, and help share the incredible work happening across the college. Along the way, interns will build a portfolio of publishable work that can support future opportunities, including graduate school, fellowships, and careers in science communication and media.

Huge thank you to our colleagues in Marketing and Communications, especially Mollie Radzinski and Bob @BobFinnerty, for supporting this initiative!

What a tremendous honor! So nice, it was selected twice!

A stunning James Webb Space Telescope (JWST) image of the Red Spider Planetary Nebula, studied by @RITscience faculty member Dr. Joel Kastner and his colleagues and students, has been selected as the NASA Astronomy Picture of the Day for February 3, 2026. Even more impressively, this same image was previously chosen as Astronomy Photo of the Month in October 2025.

This recognition highlights the impact of RIT-led research and the collaborative efforts behind this remarkable work using one of the world’s most powerful space observatories. Learn more in the RIT news release, https://t.co/vOyLjV14jU

Congratulations to Dr. Kastner, his team, and all involved!
