Spiders Are Somehow Hacking Fireflies To Lure More Victims
What happens when an unfortunate bug ends up in a spider’s web? It gets bitten and wrapped in silk, and becomes a meal. But if the web belongs to an orb-weaver and the bug is a male firefly, …Hackaday
I really love this description of a retracted study: not only does it explain what was retracted (turns out men don't generally divorce their sick wives), but also it covers what the error was (a coding problem treated people who left the study as divorced) how it all went down (someone tried to replicate, asked for data and didn't get the same analysis. Contacted the authors and they were horrified and immediately worked to retract).
It's a really nice story of why replication matters and how to be good at science. This is how I was taught science should work, but I rarely come across such good retrospectives.

A widely reported finding that the risk of divorce increases when wives fall ill — but not when men do — is invalid, thanks to a short string of mistaken coding that negates the origina…Retraction Watch

What is "normal" anyway?
Astronomers have found multi-planet systems around a number of nearby stars, but none that's much like our own. They're not a lot like each other, either.
We still don't know what a normal planetary system looks like, or if there even is such a thing.

Unraveling The Mysteries Of Planet Formation And Evolution In A Distant Solar System - Astrobiology

Ooh, look I read another paper. Hurrah !
This one is about an incredibly, superlatively faint galaxy discovered back in 2018 that I'd forgotten about completely. Here the authors use Hubble observations to rule out an old stellar population - it only has young stars. This most likely means it's a tidal dwarf, having just recently formed due to tidal interactions but not likely to last long.

Physicist John Tyndall is often credited w discovering the greenhouse effect, which he wrote about in 1859.
But Eunice Foote published a paper - 3yrs earlier - demonstrating how atmospheric water vapor & CO2 affected solar heating. She theorized that heat trapping gases in Earth’s atmosphere warm its climate.
Tyndall was widely read. And Foote, being a woman, wasn't even permitted to present her own work. http://www.climate.gov/news-features/features/happy-200th-birthday-eunice-foote-hidden-climate-science-pioneer #history #science #ClimateChange

"The discovery of this ceramic water pipe network is remarkable because the people of Pingliangtai were able to build and maintain this advanced water management system with stone age tools and without the organization of a central power structure. This system would have required a significant level of community-wide planning and coordination, and it was all done communally."

When the seas are boiling and the sky is on fire, don't come crawling to science looking for help.
#Science has tried to help us for decades. Science saw this coming, crafted solutions, and shouted them from the rooftops. Those in power did not listen.

On my way back from buying yet another LEGO bin from the mom of a 13-year old boy who’s done with it, I stumbled on the Open Source gallery in the South Slope neighborhood of #Brooklyn.
It isn’t so much a gallery as a reconverted residential garage, but the current exposition PRECIPITATE by the SCOPE collective is definitely thought-provoking. I’ve been joking for years about the #Gowanus canal and how unhealthy it is thanks to decades of industrial sewage pumping into it, but this collective of artists and scientists decided to embrace this reality and exhibit the living sediment that evolved to survive the highly toxic man-made environment of the canal waters.
