Poster on the seminar given at Leipzig university depicting droplets including particle that become active under light illumination know as emergent behavior.

Excited to give a whole seminar series on the hot topic of “Emergent Life-Like Dynamics in Synthetic Active Matter”

Many interesting ideas out there that I will discuss with the students.

If you know of articles that I should include, comment.

Dark forces are preventing us fighting the climate crisis – by taking knowledge hostage | George Monbiot The fundamental problem is this: that most of the means of communication are owned or influenced by the very rich, says Guardian columnist George Monbiot

„It didn’t happen by accident. It’s the product of a deliberate and systematic assault on knowledge by some of the richest people on Earth. Preventing climate breakdown means protecting ourselves from the storm of lies.“

Harald Lesch hat zu 100% recht! "Technologieoffenheit ist häufig ein Ausdruck für technologische Ahnungslosigkeit" und "Die Wärmepumpe ist die beste Maschine, die die Physik anzubieten hat, da gibt es keine Alternative"

Endlich rechnet mal jemand mit diesem Bullshit-Argument der Union ab.

Conservationist Jane Goodall, whose work revolutionized the study of primates, has died | CNN Jane Goodall, whose lifelong work as a primatologist helped broaden the world’s understanding of animal behavior and emotions, has died, her institute said Wednesday. She was 91.

Sad to hear that Jane Goodell, a pioneering primatologist, has died. She was one of the first to study primates in their natural habitat, live with them and truly trying to understand their connection to us humans.

To me she has been a great source of inspiration. We truly lost a great person!

Was a pleasure having you!

Where do you see the advantage compared to microfluidics, which can manipulate more cells at faster rates?

Great to see my interview on Optics&Photonics News got published now

You can learn more about my own career choices, how I navigated academic and industrial environments and how a changing mindset opened up new opportunities for me.

Thanks Rachel for sharing my story! @optica-opn.org

Science content on Bluesky attracts more engagement and originality than on X New social media site is proving better for sharing research findings

With social media site Bluesky growing in popularity among academics, a new study has revealed how it measures up against X when it comes to sharing and promoting scientific research.

The EU surrendered to Trump over trade tariffs – now it’s in danger of capitulating again | Thierry Breton A fresh US assault is aimed at Europe’s right to regulate tech. It’s an outrage – and we must resist it, says former European commissioner Thierry Breton

🚀 Our light-powered, reconfigurable #microfluidics opens the door to multifunctional, adaptive devices, which are ideal for lab-on-chip chemical synthesis, diagnostics, cell and analyte handling. These feedback-tuned thermal landscapes could transform compact experimental workflows. #optothermal

🎯📏 Arrays sort particles by size similar to a microscopic version of a Galton board 🎲 using only light & heat 🌞💧. Larger ones deflect differently than smaller ones, enabling precise, programmable sorting with no pumps or any moving parts.

💡🎛️ Projected patterns via a spatial light modulator form barriers that steer ↩️, split ✂️, merge ➕, or trap 🌀 particles. Designs switch in <100 ms ⚡ enabling real-time reconfiguration for complex microfluidic tasks.

Brief summary: 🔬✨ Using structured light, we created 3D thermal barriers 🌡️💧 in microchannels without requiring any walls! Barriers reshape flow & move particles 🎯 on-demand, enabling fast, contact-free control for lab-on-chip systems.

It's out & hot 🔥 Not only because it just went online but since we show that engineered heat patterns are super effective in manipulating fluid flows & particles.
