When your research assistant is a massive trekkie you get awesome lab archives entries such as this

Registrations for the #Lipidomics #GRC close soon. Don't miss this chance to learn from and engage with leaders in the field #TeamMassSpec 🧪 www.grc.org/lipidomics-c...

Found on LinkedIn alongside text describing how PCR works. 😂. #TeamMassSpec #massspectrometry #science #badai

Super gross stuff

*inaccessible region. That's what I get for posting before coffee

Fatberg the size of four buses likely birthed poo balls that closed Sydney beaches – and it can’t be cleared Exclusive: Secret report suggests fats, oils and grease accumulate in ‘inaccessible dead zone’ at Malabar plant, then dislodge when pumping pressure ‘rapidly increases’

Turns out the Sydney beach poo balls we analysed in late 2024 might be baby poo balls birthed from a giant fatberg stuck in an accessible region of Sydney's waste water system. #TeamMassSpec

#NHMRC Ideas grant success rate was 8.1% this year. This is not sustainable.

Super thrilled to have this one accepted at AnalChem last week. Nice way to see out the end of the year. 🎉 #lipidomics #TeamMassSpec

Celebrating Dr Banks (@jasmineleighb.bsky.social) and Dr Govindäraj (@hemnaphd.bsky.social) who graduated last Friday! 👩🏻‍🎓 🎉
Wishing you the very best for the many exciting adventures to come!

@phenylauraline.bsky.social is on 🔥🔥🔥 taking out the Paul Korner Seminar awards for two consecutive years. #TeamMassSpec #lipidomics

Gambling on the electricity market: summer heatwave edition

FTR I would totally have this student back for a PhD but she is international and we currently don't have any stipend funding support for her. I'm working on it but in the meantme actively supporting her other applications.

The worst, especially when you're on >1 app with multiple interruptions.

RIP James Watson. I'll always remember you as the dude berating the cafeteria staff at CSHL because they served turkey bacon on the open day.

Our very own newly minted PhD @jasmineleighb.bsky.social is the @victorchang.edu.au Star Scientist for November. Best of all, she's currently looking for postdoc opportunities for 2026. Hit her up if you think she might be a good fit for your lab. #teammassspec #obesity #nad 👩‍🔬🧪

Pretty much :)

Epoxidation-enhanced charge-switch derivatization for rapid profiling of monounsaturated fatty acid isomers Structural isomerism in monounsaturated fatty acids (MUFAs) presents a persistent challenge in lipidomics due to limited chromatographic resolution and indistinguishable mass spectral profiles. Moreover, many methods that overcome these limitations require specialized instruments or complex photochemistry typically not accessible in for those using standard lipidomics core facilities. We report a streamlined LC-MS/MS method that integrates N-(4-aminomethylphenyl)pyridinium (AMP)-based charge-switch derivatization with meta-chloroperoxybenzoic acid (mCPBA) epoxidation to enable rapid and sensitive profiling of MUFA double bond positional isomers. Charge-switching enables enhanced detection of fatty acids while epoxidation improves chromatographic resolution and produces diagnostic fragmentation patterns upon collision-induced dissociation (CID), enabling precise localization of double bond positions. The optimized workflow achieves baseline separation of 16:1, 18:1, and 20:1 MUFA isomers within a 20-minute gradient, with reproducible retention times and consistent epoxide yields. The method also supports partial resolution of polyunsaturated fatty acids (PUFA) and cis/trans isomers. Application to prostate cancer cell lines revealed distinct MUFA isomer profiles associated with aberrant fatty acid desaturase 2 (FADS2) activity, including elevated n-10 and n-12 isomers in tumorigenic lines. These results align with prior studies using other isomer-resolving techniques, validating the method’s analytical performance. This accessible and robust strategy expands the toolkit for lipidomics research, providing a method that is compatible with conventional LC-MS/MS workflows, positioning it as a practical solution for high-resolution isomer analysis in complex biological samples

I put this one up quietly on @chemrxiv.org before disappearing on annual leave for 3 weeks. It is a quick and useful technique for those of us who want to do isomer-resolved #lipidomics but don't have access to modified instruments. doi.org/10.26434/che... #teammassspec #massspec

Also, men who are invited to speak at these conferences: be good allies and speak up! Refuse the invitation or make your acceptance conditional on the organisers achieving gender parity. Suggest speakers from underrepresented groups that you know are great and don't get the recognition they deserve.

To be honest, when I see conferences announced that have a majority of male invited speakers, I think the organisers are not trying hard enough. We have so many excellent #FemalesinMS and resources available there is really no excuse for it anymore #massspec #teammassspec #lipidomics #metabolomics

You can hear the Bells Miner birds in the background - we counted 18 in 20 mins for the Aussie Bird Count yesterday

Met this little fella at Hobart Beach National Park. Not shy at all.

How your email has found me this past week

My daughter asked for crocs today. I guess it's only a matter of time before she starts saying things like "water, like out the toilet?" and "it's got what plants crave".

Today I visited my kids preschool to talk about science for #nationalscienceweek2025. My mini-me and I talked about an experiment we did on germs 🦠. We talked about different kinds of scientists and asked the children what kind of scientist they would like to be

Does anyone in #lipid research know if Nu-check prep is still operating? Their website is down and I can't see anything on the wayback from the end of last year...

Gambling on the electricity market is paying off tonight

#Sydney CBD was super foggy this morning

Possibly the greatest compliment I'm going to receive today
