Looking for someone in CT who works in physics.. preferably nuclear.. for a 2-day job shadow. Can my Twitteratie hook a girl up?

Just saw this gem for the first time today youtube.com/watch?v=bzE-IM…

Our paper on different RT-FD-SPT methods has been accepted in JCP! doi.org/10.1063/5.0096…. Thank you @TjaartKrueger. @UPTuks @UPnasagric.

The image taken by the JWST compared to one taken by Hubble, of the galaxy cluster SMACS 0723. It's s a gravitational lens, showing us the light of galaxies that are far behind the cluster in arcs around it. I tried to orient them the same. LOOK AT THE DIFFERENCE.

@mec_mitchell @WCGovTPW @WCGovSafelyHome People don’t walk drunk on roads out of stupidity - people do not own cars and there’s no public transport at night or on weekends. Where else should they walk or how do they get from the social place home? We need services & infrastructure in communities that need them…

Key findings: Minflux is precise but slow. Knight's Tour is very fast but less precise. iSCAT outperforms fluorescence for most biological particles.

Happy to finally share our preprint on comparing real-time feedback-driven single-particle tracking methods. arxiv.org/abs/2207.02210. We compare orbital, Knight's Tour and #MINFLUX, in the context of #fluorescence and #iSCAT.

Yo @CityTshwane @tshwane_mayor we need to talk. The ignoring of pedestrians must stop. We cannot keep building, expanding or refurbishing roads while not building sidewalks. So many people walk as a form of transport but there are no sidewalks. Increasing the chances of accidents

South Africa could, at any point, end power cuts in 18 months if Gwede stopped curtailing the growth of the wind, solar and battery industry. But no - he’s too obsessed with another 15 year coal build project. news24.com/citypress/busi…

@the_transit_guy Pretoria, South Africa

How great would it be if every street had mature tree canopies like this? Planting small trees today will bear the fruits of tomorrow (literally)!

@NewStreetsSA @amirofthecape You might even say they are "streets ahead"...

@amirofthecape Many Cape Town townships are are already a step ahead of the suburbs, given that they often developed without cars in very constricted spaces. For example, Nomazomo here, could be car free/ car light tomorrow. twitter.com/NewStreetsSA/s…

4 lanes of heavy traffic Versus a low traffic cycle street One degrades your city, the other makes it more pleasant.

As an urbanised country, I argued in @dailymaverick it is evident from the design of our cities, the dissonance between the lofty ideals we have & the reality we face daily, that 16 June cannot continue to be commemorated as per-usual. @UrbanLo @urbanjodi dailymaverick.co.za/article/2022-0…

@AnderssonBu It was great working with you!

New review article by Vickers and Andersson (in collaboration with colleagues from the University of Pretoria) on real-time, feedback-driven single particle tracking. Check it out! onlinelibrary.wiley.com/doi/10.1002/sm…

I'm delighted that our review on real-time single-particle tracking appeared today in #Small. Great collaboration with @bertusvheerden, Nic Vickers, and Sean Andersson! @AdvSciNews onlinelibrary.wiley.com/doi/full/10.10…

A tricky thing in science is to learn to always doubt your results, but never doubt yourself.

"Substantial" #climatechange mitigation potential of #agroforestry: New study by Zomer et al: "Increasing global tree cover on ag land by 10% would sequester more than 18 PgC. S. America has highest potential followed by SE Asia, W. Central Africa...” maxapress.com/article/doi/10…

The painted cycle lanes in Merriman Avenue are unsafe, used by many commuters especially students daily as we point out in this week’s #Eikestadnuus
