With Hillier, Aro, Farquhar, Atkin to understand how to convert photons and gasses into sugars. Loving science, policy, oxygen and everything in between.

In contrast to C3 plants, increasing content of SBPase in C4 plant does not improve photosynthesis. This is important for understanding regulation of carbon fluxes in the C4 system. Thanks to co-authors @SvonCaemmerer @rainc_CAR1 @bobfurbank @LopezCalcagno and funds @leaf2field
Increased sedoheptulose-1,7-bisphosphatase content in the C4 species Setaria viridis does not affect photosynthesis biorxiv.org/cgi/content/shor… #bioRxiv
Our data shows that hydrogen peroxide can only ACCUMULATE at PSI. We agree it may form anywhere along the chloroplast ETC. But if it doesn't accumulate, it can't participate in a direct retrograde signal. The old models are wrong and based on an artifact!

We previously showed DNP-INT doesn't inhibit electron transport to PSI - it fails to block CO2 assimilation or spectroscopic PSI reduction. Now we show previous work using DNP-INT measured H2O2 artifacts from still active PSI! Retrograde H2O2 signal conveys a PSI acceptor limit.
This is a step forward. It helps understand how chloroplast energetics are poised and buffered against acute environmental changes but resilient to chronic shifts. It suggests pathways for mitochondria to interact with the chloroplast. #plantphys

Third year @BiologyANU plant science prac. 6 mutants, 6 groups, 6 @LICOR_ENV 6800s, @flir, (>$500k in hardware), 8 highly qualified plant scientist demonstrators. No masks. Why would you study anything else? @PlantSci_ANU, @scienceANU
A colourful addition to the Farquhar lab today, created by the talented Nina Roderick. @RSB_PlantSci
Exciting opportunity for a four year PhD position, devleoping water oxidation catalysts with @cheahhonmun, Uppsala Uni @uppsalauni in Sweden! Nordic PhDs are so well funded and supported, and water oxidation catalysts may change the world! Apply! RT!

Outstanding work, demonstrating the value of developing new experimental techniques to interrogate the small details and improve our assumptions. @DiegoMa_rquez has shown us the path forward in gas exchange precision @NaturePlants
New paper out in @NaturePlants with Hilary Stuart-Williams and @GrahamDFarquhar. Our theory is a more precise physical approach to the electrical resistance analogy for gas exchange, including the cuticular fluxes.

The first step for ancient man towards modern civilisation was probably construction of rain proof shelters. Are Australian tradies, protected by government subsidy, consistantly unable to build a leak proof roof, regressing that far? Get your shit together, you have one job!
The socially distanced HDR conference @BiologyANU. Really impressive work on display. Thankful to not be a judge.
I stand with all SMART people, the BEST people. Stop the cunt!
Oh.... they said count. How embarrassing. Nah, probably keep counting.

Public policy, like OHS, can only be as strong as the assumptions it is based on. We have cleaners disinfecting all door handles, but I've noticed nobody uses the handles because swipe card readers make them redundant. Smudged glass tells the true story. #covidfail
Real estate agents: take half your salary, judge how clean you are based on your oven, decide if your friends may live with you and apparently, haven't learnt the difference between sourdough and a border collie.
The dirtiest job in science is to convince a field that they are wrong about something. You won't make friends, citations may be low, but it paves the way for better understanding. Here we question a 40 year dogma, coming next we'll show why it matters. frontiersin.org/article/10.3…
This is not about politics, it is about governance. Who is spending stimulus on what? You can't go outside anyway, so participate in some armchair democracy and throw your name behind this important initiative nb.tai.org.au/covid19_commit…
