How do rivers actually shape our planet—at a global scale? A new study published in GSA Today is changing the way scientists answer that question—using data from NASA’s SWOT satellite to track how rivers erode, transport sediment, and reshape landscapes across Earth. Traditionally, studying rivers meant detailed (but localized) fieldwork. Now, this research shows how we can monitor river dynamics worldwide—from shifting channels and sediment transport to knickpoints, floods, and even dam failures—all in near real time. In this new era of fluvial geomorphology where we can connect local river processes to global patterns, we can also better understand risks to infrastructure, ecosystems, and communities. This work is already gaining broader attention and has been featured in MSN and Yahoo News—but the full story and the science behind it starts with the original paper: geosociety.co/Stroud_et_al #NASA #RemoteSensing #Geomorphology

@sciam Yes, an undeniable advantage !

The Department of Health and Human Services and the Environmental Protection Agency announced a joint effort to track microplastics in drinking water—but experts say doing so will be difficult spklr.io/6010EyIIq

Quelqu’un peut-il m’expliquer en quoi considérer un noir - ou un blanc- comme un « mâle dominant » est raciste ? Celui qui pense cela est soit un con , soit un menteur. Encore que les notions ne soient pas incompatibles. Soutien à @MichelOnfray4 dont je m’honore d’être l’ami.

@NamiKim_DogsSK @WeAreNotFood Thank you for your pertinence and commitment ❗🏵️💐💐💐

Our support against the heinous #DogCatMeatTrade in #China Sharing from .@WeAreNotFood ➡️facebook.com/reel/143670382… "In March, 2026, Chinese activists conducted research on the number of dogs and cats slaughtered for human consumption. I also contributed to this research to a small extent. The results were startling. The numbers (estimates) are bigger than previously reported, especially by western operators. The estimated number of dogs slaughtered in China every year is 15-20 million. For cats, the estimated number is 5-8.5 million. To slaughter dogs and cats for human consumption is illegal. And so is the selling of their meat. Thus, the dog and cat meat trade is illegal. To eat dog or cat meat is legal though'" #illegaldogmeattrade #wearenotfood #bantheconsumptionofdogs #illegalcatmeattrade #bantheconsumptionofcats #BoycottChina until it puts an end to this hell!

🆕NEWS FROM #SouthKorea - DOGS EXTERMINATED Sharing from Haeng Gang - Korean Org for Animal's Right ➡️facebook.com/haeng.gang/pos… "Our tribute is to you Hope it will be well with you guys Citizens and peer groups gathered in #Gunsan last weekend to remember the dogs that were abandoned in the Hongdong warehouse while being killed anonymously in the #dogfoodindustry and send them a peaceful end. Victim dogs are lit up inside the warehouse, right next to the warehouse where the horrific slaughter took place. The ice was stuck on the bodies of the victim dogs that it couldn't be understood how long it had been there. Before the first step to arrange a funeral, I carefully took a couple of them out of the warehouse with time of contemplation ahead of the "humidity". The appearance of the sacrificial dogs under the descending rain was more agonizing than I imagined. About 200 victim dogs had their intestines removed with their abdominals split, their noses were cut, and the sole pads were cut with a knife. Was it intended to distract dogs from electric shock? Or was the purpose of cutting off a dog's body parts like a loot? In the meantime, I have raided numerous slaughterhouses and witnessed victim dogs, but I have never seen such a cruel scene. So the end of the dogs shouldn't be this way. The sacrificial dogs that came out of the world from Chadichan's freezer were moved to the white river with a caring touch. And the memorial service was held in everyone's prayers. #Yesoyeon's memorial service, reading of names sent by citizens, commemorative comments from groups and citizens echoed on the scene. #YeRam's memorial performance has touched everyone's hearts. This is a place to ask again how our society should deal with the deaths of dogs sacrificed for illegal slaughter. On February 7, 2027, wants to urge the active role of the government and municipalities to ensure that the remaining dogs on the dog farm and other places will no longer be abused and slaughtered during the "detention period" before the complete end of the dog food industry. The faces of victim dogs blinded by fear and pain. I will never forget." #EndDogMeatTrade

Une 9ème année vient de s'écouler pour AVA et l'opposition à la barbarie féodale en forêt de Compiègne ! Et nous serons là pour une 10ème année 🥳 Depuis 9 ans, le mouvement anti chasse à courre a survécu à la violence, à une véritable milice en uniforme employée contre nous, à une complicité ouverte de l'État au service de ces notables sanguinaires, à la lassitude de voir le processus politique bloqué, aux intimidations diverses... 9 ans, et AVA est toujours là ! C'est le mouvement le plus long et le plus intense qu'ait connu le pays contre la chasse à courre. Et ce n'est pas rien de le dire dans la ville qui a connu la glorieuse SAF des années 80, dont AVA a repris la tradition. Rien que dans la forêt de Compiègne, ce sont 80 cerfs qui ont pu être sauvés d'une mort atroce, divisant par deux le massacre de l'équipage d'Alain Drach par rapport à il y a 9 ans 🙏

When farming with soil health in mind, it is not enough to have high plant diversity. Crop rotation, intercropping, and animal diversity help with #soil health. Learn more in our #GroundedInSoils blog post: wp.me/pclOv9-f1

This feels like early April Fools, but it’s real life. The pink lady’s slipper flower “kidnaps” bees. A bee sees the bright flower. “Finally, nectar.” It goes in. There is no nectar. Now it’s stuck. The only way out is a tight exit that dusts it with pollen. The bee escapes and then gets lured into another pink lady’s slipper, gets trapped again, and delivers pollen to the next flower. No joke. Just a native orchid running a full pollination scam. Photo by Keith Ramos/USFWS
