"I had spent half my life working toward my dream of being a scientist. It had given me a sense of purpose. But now it dawned on me that, for the sake of my health, I was going to have to let that dream go." #MentalHealthAwarenessMonth
Science used to be my safe space. But when I spiraled into depression, I quit my Ph.D.
The author had been using research “as a way of trying to control the uncontrollable”

Ok, this is particularly concerning
Tiny plastic particles may accumulate at higher levels in the human brain than in the kidney and liver, with greater concentrations detected in postmortem samples from 2024 than in those from 2016, suggests a paper in Nature Medicine. https://go.nature.com/414lf9S #Medsky 🧪

It's time to share a high level of science. I love this paper; when it was published, my reaction was 😱. Because I always ask, why do we look at the same cells all the time? Why do we call them 'neurons & glia'? Why weren’t the brain cells classified in the same way?
