(or, A Hodge-Podge of Fact and Opinion) By Josh Kearns I’ve just returned from an arduous – but tremendously joyful – trip to a small village in the remote coastal mountains of Burma’s “Deep South,” Tenasserim Division. The trip took two weeks and consisted of nearly four days of travel – each way – over …

Researchers have developed a new polymyxin-like lipopeptide to kill multidrug-resistant microbes (superbugs). In the past, when facing bacteria that are resistant to antibiotics, doctors could prescribe polymyxins. Polymyxins are lipopeptides that kill bacteria by binding to a component of the cell wall and disrupting ionic and hydrophobic interactions. Polymyxin-resistant bacteria have evolved so that they …
By Josh Kearns I’ve had a lot of unpopular ideas. Maybe the all-time most unpopular, though, is this one: The relatively short trips made by international humanitarian science/engineering and sustainable community development professionals for fieldwork, particularly to far-flung destinations, are almost certainly futile from an environmental sustainability perspective. Most of us in the international “humanitarian …
By Josh Kearns Crowdsourcing is by now thoroughly established as an internet meme. How do I know this? Because I’m aware of it. Compared to today’s hip and uber-connected Millennials, I’m a hopelessly antiquarian Gen-Xer. I do not and hope to never own a smart phone. (My career aspiration is to eventually go “full Wendell …

Biochemists and microbiologists: Aqueous Solutions has a mission for you. By Josh Kearns I recently visited two village training centers deep in the wilds of Tenasserim district (Thailand-Burma border region), where colleagues and I conducted follow-up inspections on water treatment systems installed by local trainees during recent months. (Check out our Facebook page for photos from …

Part I: Contemplation of the Energy Return on Investment (EROI) Author’s note This post is a bit longer (and headier) than previous posts, but herein I open a very complex and somewhat controversial constellation of subjects, and attempt to treat matters in a cross-disciplinary manner and at the root-level. My intention in blogging for Chemists …
A Chemist’s Critique of Economics and “Sustainable Development” Read More »
By Josh Kearns Readers of this blog probably don’t have to be told that the proliferation of synthetic chemicals over the past century has hugely impacted drinking water sources around the world. But you might be shocked to learn that these toxic contaminants are completely ignored by international, governmental and non-governmental agencies concerned with expanding …
Making “Low-Tech” Biochar Adsorbent For Decentralized Water Treatment Read More »
by Josh Kearns For this, my second post on the Chemists Without Borders blog, I had prepared a more “academic-sounding” post about Making “Low-Tech” Biochar Adsorbent For Decentralized Water Treatment. While that’s an interesting topic (I hope…), we’ll save that discussion for next week as I’ve just returned from a real Chemist-Without-Borders situation with visceral …

Hi! My name is Josh Kearns, and I am excited to be a guest blogger for Chemists Without Borders! I am a chemist by training – I hold a BS in chemistry with a minor in environmental engineering from Clemson University in South Carolina, and an MS in environmental biogeochemistry from the University of California-Berkeley. …
