Maybe its🙏 good karma, but the songs of the returning redwing blackbirds and Spring peepers seem to really enjoy a mild misty March (Mars?) morning shower 🏡⛈️⛰️🌎, instead of another dusting of snow from a cold front blowing through

On the left, a coastal outcrop of gray limestone with an irregular surface and people walking on it in the background; on the right is shallow aquamarine ocean water over a rocky-sandy bottom; in the background is a small patch of white sand beach with green vegetation behind it and a blue sky with clouds.

Day 7 of the 'Modern & Ancient Tropical Environments Field Course,' co-taught with Dr. Melissa Hage of Oxford College of Emory with students from both the Oxford & @emorycollege.bsky.social campuses. Lots of geological & ecological lessons from field experiences so far, with more on the way. 🧪🪨⚒️🌊🏝️

Plasma extracellular vesicles (EVs) increase during acute myocardial infarction (MI), correlate with myocardial injury, and mobilize immune cells from the spleen to the circulation. These cells are transcriptionally activated even before tissue recruitment, yet the mechanisms driving this priming are unclear. We show that plasma EVs isolated at hospital presentation with MI are enriched in miRNA-320b. Endothelial cells upregulate miRNA-320b in EVs following inflammatory stimulation. Target gene pathway analysis revealed enrichment in adhesion and cytokine signaling. Endothelial EVs promoted monocyte adhesion and induced IL6 and TNF mRNA expression in macrophages while dampening cytokine secretion. RNA-sequencing of MI patient neutrophils and monocytes confirmed significant enrichment of miRNA-320b targets. Peripheral blood mononuclear cells treated with MI plasma EVs showed similar gene regulation. These findings suggest that EV-mediated transfer of miRNA-320b primes immune cells for adhesion and cytokine signaling. Understanding this signaling axis may enable therapeutic immunomodulation of immune cells to improve repair following MI.

Targeting these signals may limit injury and improve repair. doi.org/10.1016/j.is... 🧪🫀🧬🖥️ #cardiosky #immunosky @cp-iscience.bsky.social

'They tried unsuccessfully to measure hydrogen production from gut microbes.. Frustrated, “we took the sensor out of the chamber, and we were like, ‘Screw it. We’re going to try to measure a fart.’” So Hall stuck the device down his own pants and let rip. “And the signal was enormous.”'

these ants return home from foraging trips by observing the arc of the moon and integrating it with their sense of time—the first animals known to do so 🧪

Promising breakthrough creates plastics that self-deconstruct on cue: Study Plastics have a gigantic built-in problem: They’re tenacious, which is very good for a milk jug or a car bumper. But they don’t easily break down, which is bad for the environment. From the 1950s, whe...

Plastic pollution is a global environmental crisis, but what if we could design plastics that automatically break down after use? 🧪
