If some of the published studies were to be believed, then MNPs are everywhere inside our bodies, from our blood and reproductive organs to having deeply embedded themselves inside our brains with potentially catastrophic health implications.</p>
<p>Early last year <a href="https://hackaday.com/2025/02/12/plastic-on-the-mind-assessing-the-risks-from-micro-and-nanoplastics/">we covered</a> what we thought we knew about the harm from MNPs in our bodies, but since then more and more scientists have <a href="https://www.theguardian.com/environment/2026/jan/13/microplastics-human-body-doubt" target="_blank">pushed back</a> against these studies, calling them ‘flawed’ and questioning the used methodology and conclusions. Despite claims of health damage <a href="https://hackaday.com/2025/05/26/mouse-model-suggests-starch-based-plastics-are-still-bad-for-you/">in mice</a>, institutions like the German federal risk assessment institute also <a href="https://www.bfr.bund.de/en/notification/microplastics-in-the-brain-bfr-evaluates-new-study-so-f

The images they take are spectacular, and they’ve greatly increased what we know about the universe. Surely, any picture taken of, say, the Andromeda galaxy before space telescopes would be little more than a smudge compared to modern photos, right? Maybe not.</p> <p>One of the most famous pictures of our galactic neighbor was taken in — no kidding — 1888. The astronomer/photographer was <a href="https://en.wikipedia.org/wiki/Isaac_Roberts" target="_blank">Isaac Roberts</a>, a Welsh engineer with a keen interest in astrophotography. Around 1878, he began using a 180 mm refracting telescope for observations, and in 1883, he began taking photographs.</p> <p>He was so pleased with the results that he ordered a reflecting telescope with a 510 mm first-surface mirror and built an observatory around it in 1885. Photography and optics back then weren’t what they are now, so adding more mirrors to the setup$
