Microplastics are everywhere—but our methods to track them are all over the place
A new study from the University of Portsmouth has highlighted the growing role of citizen science in tackling one of the planet's most pervasive pollution problems: microplastics and mesoplastics. While researchers often warn that a lack of standardized protocols risks muddying the waters, this research shows that public involvement could be key to plugging the data gaps and that comparability rather than conformity is key.

My 13yo held up a glass of water and asked me if it had microplastics in it. "Probably," I replied. He then said he wasn't going to drink it, and I told him that microplastics are EVERYWHERE. You can't avoid it, they're in all the water and air. I explained that it's a problem we need to solve at society's level - a huge amount of environmental microplastics come from car tires, and we need to wean ourselves off of fossil fuels.
He and the 8yo both then as…

I'm looking for inexpensive linear actuators. I bought a $15 unit that uses an M3x0.5mm threaded rod and it's not horrible, but the effector has a lot of backlash. This has more stroke than I need; I only need about 65mm of stroke. But I wouldn't want to be particularly larger than this. Roughly 20mm x 20mm x 100mm would be my target envelope.
I'll fall back to using this with backlash compensati…

"In recent times, tire wear particles have been found to account for about 45% of all microplastics in both terrestrial and aquatic systems...
Rain washes those tire wear particles into ditches, where they flow into streams, lakes, rivers and oceans...
In a recent study, we tested pine wood chips and biochar – a form or charcoal made from heating rice husks in a limited oxygen chamber, a process known as pyrolysis – and found they could remove approximately 90% of tire wear …

One of the biggest microplastic pollution sources isn’t straws or grocery bags – it’s your tires
Rain storms wash those tire shards into streams and ultimately into lakes and oceans. That’s bad news for fish and other aquatic life.

Trigger-happy female axolotls - is this a new sci-fi trope in the making? In Disney‘s recent live-action Lilo and Stitch there’s one that would be happ to blow up earth.
And a while ago I noticed one in Amazon‘s episodic „Secret Level“ that could also be described as trigger-happy: https://mograph.social/@comp…

The Morpho-Kinetic Landscape of Macrophage Modes During Wound Healing in Zebrafish
Macrophages play an essential role in wound healing due to their dynamic nature and functional plasticity, exhibiting highly heterogeneous morpho-kinetic behaviors depending on their activation states. However, quantitative analysis of macrophage behavior in in vivo settings remains limited, largely due to the complexity of their diverse morphologies and motility patterns over time. In this study, we present an analytic workflow to investigate macrophage dynamics in zebrafish. By computing a co…

Diffusioosmotic flow in a soft microfluidic configuration induces fluid-structure instability
Diffusioosmotic flow arises in microfluidic configurations due to solute concentration gradients. In soft microfluidic channels, internal pressure gradients generated by diffusioosmotic flow to conserve mass result in elastic deformation of the channel walls, triggering fluid-structure interaction. In this work, we analyze the fluid-structure interaction between diffusioosmotic flow of an electrolyte solution and a deformable microfluidic channel. We provide insight into the physical behavior o…
