Researchers detect blue-green algae toxin in Lake Erie earlier than ever before
Researchers at the Great Lakes Environmental Research Lab say they have detected a harmful toxin produced by blue green algae far earlier in the year than ever before in Lake Erie.

Scientists Detect Unusual Airborne Toxin in the United States for the First Time

MCCPs are currently under consideration for regulation by the Stockholm Convention, a global treaty to protect human health from long-standing and widespread chemicals. While the toxic pollutants have been measured in Antarctica and Asia, researchers haven’t been sure how to document them in the Western Hemisphere’s atmosphere until now.

Bacteria use toxic effectors to outcompete other bacteria. This study shows that the cysteine protease Cpe1, a widespread #toxin in Gram negative #bacteria, inhibits replication in competitors by cleaving & disabling DNA #topoisomerases GyrB & ParE @PLOSBiology https://plos.io/4dyEVXL

Top: Ribbon diagrams of E. coli GyrB (left) and ParE (right) before and after cleavage by Cpe1tox. Crystal structures of the 43-kDa ATPase domain of E. coli GyrB (PDB: 4PRV) and ParE (PDB: 1S16) were used. Residues of the consensus sequence (LHAGGKF) are shown in yellow. Structure related to the small fragments after Cpe1tox cleavage are indicated as pink ribbons. Predicted structures after cleavage at the double glycine motif demonstrated disruption of the ATPase domain of both GyrB and ParE. Bottom: Working model of how Cpe1 intoxicates bacteria. During interbacterial competition, Cpe1 targets and cleaves the ATPase domains of GyrB and ParE in target cells. The cleavage leads to accumulations of unrelaxed supercoils and precatenanes, disrupts DNA segregation, and ultimately inhibits cell division and growth. In the Cpe1-producing cells or kin cells expressing the immunity protein Cpi1, Cpe1 toxicity is neutralized through direct interaction between Cpe1 and Cpi1.

#Celegans peel-1/zeel-1 is one of the best-characterized animal #toxin-antidote systems, but how does it work? This study shows that PEEL-1 co-opts the PMPL-1 to exert toxicity by creating a novel #IonChannel that leads to cell swelling @PLOSBiology https://plos.io/3HfH8LN

Selected frames of a live-cell imaging time-course experiment. A single cell is shown, co-expressing PEEL-1::eGFP and PMPL-1::mCherry. The nucleus is labeled (“N”). t = 0 is 16 hrs after transfection. Acute swelling can be seen (t = 2 hr 30 min), followed by a transient blob or protrusion (arrow) jetted out by the cell (t = 4 hr 15 min) and later reabsorbed (dotted arrow) (t = 4 hr 20 min). Scale bar = 10 µm.

After years of aggressive expansion
we now gotta admit
that the perimeter is shrinking

Push back against
are share the hate agenda
was greater than anticipated

We'll leave it to biased historians
to analyze why our movement failed
but now we gotta execute
a regrettable exit strategy

The EU has banned BPAs: here’s what you need to know about this common, toxic compound.

The European Union has banned the use of bisphenol A (BPA), an endocrine disruptor widely used in plastics.

This came into effect with Regulation 2024/3190 in late 2024, but it took over 20 years of scientific study to cut out this silent toxin.

Der Mikroorganismus Prymnesium parvum sondert #Gift ab, das Membranen wie die Kiemen von Fischen zerstören kann. Begünstigt wird das Wachstum der Mikroalge durch das warme Salzwasser von polnischen Bergwerken. So wie es aussieht, wird #Polen die Salzeinleitung nicht kurzfristig stoppen.

Weekend #Plankton #Factoid 🦠🦐
Summer is when reports of Harmful Algal Blooms (#HABs) happen in freshwaters, almost always caused by #cyanobacteria. Commonly referred to as blue-green #algae because of a distinct phycocyanin pigment, they are in fact a type of photosynthetic #bacteria. Not all cyano species cause HABs, but some can produce several toxins, most commonly microcystin-LR, a hepatic (liver) #toxin dangerous to drinking #water, but is also *very toxic to dogs.
