‘One of the larger mysteries I’ve ever seen’: Industrial chemical found in illicit fentanyl | CNN

One of the best experiences of my life was doing a working holiday in New Zealand in my early 20s. Easy visa to get online, a year, and other countries also have, usually for ppl under 30. Always down to chat answer what questions I can about the process.

Scientists, academics, researchers: We’re excited to share that @altmetric.com is now tracking mentions of your research on Bluesky! 🧪
There are already many articles for which there is more attention on Bluesky than on other comparable micro-blogging sites, meaning the academic community and the general public have clearly adopted Bluesky as one of its core places to disseminate and discuss new research.
