Focusing on Sweden, this study finds that PhD students begin their programs with similar psychiatric medication use as other master’s graduates, but usage rises sharply to about 40 percent higher by the fifth year before declining after graduation.

Hamburg just said YES in the climate referendum! ♥️
Thanks to everyone who fought for it.
This vote matters for Hamburg – and sends a strong signal far beyond.
The climate issue is alive: we can set the agenda and win!
Another lesson: climate action must go hand in hand with social justice.

Of course I heard a bit about it before but only today I really started looking into the business of academic publishers. Omfg. It's one of the most absurd appropriations of public money and voluntary work for insane private profits that I ever heard of. How are we all participating in this system?

Tools like the Climate Shift Index show this heatwave is up to 5x 😱 more likely because of climate change. That context matters.
