Congratulations to LS1 grantees @hecklab.bsky.social and Annarita Miccio at @institutimagine.bsky.social , for being awarded ERC POC grants! :)

Since the 1960s, the genetic code has been used to predict protein sequences from DNA and mRNA sequences. Our @nature.com article demonstrates that these predictions miss thousands of protein sequences present in human tissues. www.nature.com/articles/s41... 1/

Our article is out in Nature Communications! We identify ATP synthase as a new link between OXPHOS and the TCA cycle, and these interactions are remodelled upon mitochondrial dysfunction. Co-authored with Jelena Misic, @tkadava.bsky.social, @nils-goranlarsson.bsky.social, @hecklab.bsky.social

It was great to have you @asms.org #ASMS2026 in San Diego! Your Plenary Lecture was a great way to end our conference. I hope you didn't mind talking about Science Integrity continuously during the USS Midway tour afterwards with our members. Thanks for discussing this important topic in science.

Traveling today to San Diego, to give the closing plenary at the @asms.org #ASMS2026 #MassSpectrometry meeting. I am not aware of a lot of MS fraud, and would have a hard time finding it myself, but hopefully we can learn from each other. This might be my biggest audience ever (7K participants)!

#ASMS2026 Huge congratulations to Albert @hecklab.bsky.social for winning the ASMS John Fenn award for a Distinguished contribution in Mass spectrometry! well-deserved! A truly inspiring talk👍👏✨

Congratulations to Albert J.R. Heck, recipient of the 2026 #ASMS John B. Fenn Award for Distinguished Contribution! A leader in the field, his work continues to shape the future of #massspectrometry. We’re excited to celebrate his achievements at #ASMS2026 in San Diego.

I wonder... 🤔🤔🧪 #chemsky a) what program did the authors use to make the original (left) figure in the paper? Wild guess, ChatGPT b) how such high school science level of disgrace pass peer review in @nature.com? Note this was Fig.4.a NOT in SI www.nature.com/articles/s41...

Got an Orbitrap-based mass spec that couldn’t do STORI/direct mass technology before (any aside from the UHMR and Tribrid Ascend)? This is a cool open-source implementation that even works on an Orbitrap Elite! #teammassspec

New plasma glycoproteomics method out of the @hecklab.bsky.social uses narrow-window DIA on Orbitrap Astral with Aurora Ultimate XT column. 50% more glycopeptide IDs vs. traditional approaches, with 181 glycoproteins detected across 7 orders of magnitude in just 10-40 minute runs. bit.ly/45bDXhv
