Reply to comment by oasiscat in A new study suggests that too much screen time during infancy may lead to changes in brain activity, as well as problems with executive functioning — the ability to stay focused and control impulses, behaviors, and emotions — in elementary school. by Wagamaga

Is it designed to be overstimulating? Or perhaps they designed it stimulating enough to keep the attention a human with very very little attention span. To be honest it would not be a successful baby show if it did not draw their attention or interest, its more so about moderating how much they watch

Reply to comment by enirgin in Vitamin D supplements linked to reduced risk of suicide, study of veterans finds by thebelsnickle1991

getting a vitamin D prescription filled also indicates this person is in regular contact with a medical provider.

Given that you can easily get vitamin d without a prescription, I'd say the fact they are seeing a doctor is a bigger factor.

​

That being said, anecdotally I find if I forget to take vitamin D in the winter I experience some seasonal depression and fatigue.

My nephew wants to play with my sister-in-law’s phone whenever he sees it. He’s 18 months now. He’s been doing this since he was around six months old.

I changed the settings on my sons iPad so that I can control how much time he gets. I give him access in 15 minute increments. That’s it.

We will watch movies on the weekends sometimes as a treat.

Screens are everywhere. It’s a constant battle.

I started taking vitamin D and my depression symptoms improved, so I experienced that correlation first-hand. I began taking it per doctor advice. This was very much not the only change in my life at the time.

Some obvious confounding factors to consider: this resulted from first contact with a doctor regarding my depression symptoms and the initiation of a holistic care plan, began taking SSRIs, began therapy, changed living/working arrangements to remove sources of excessive stress, increased social contact with friends/family, generally started taking better care of myself when I was capable again.

Reply to New review finds that rocket emissions in the upper atmosphere can affect the ozone layer but are not regulated — Global annual launches grew from 90 to 190 in the past 5 years, and an upsurge in rocket launches may potentially undo decades of work to save the ozone layer by marketrent

Uh am I just blind, or is there no actual data here, just some dudes waving their hands and hypothesizing stuff they think is plausible?

And that hypothesis, even, is especially un-compelling IMO when they include hypergolic propellants in the list: that is the source of most of the super toxic shit BUT is also definitely not the propellant being used in the vast majority of those extra 100 launches.

Hypergolics are used for military rockets mostly where stable storage for years is the main concern. Commercial launches use almost entirely vastly cleaner RP-1 refined kerosene, hydrogen, or methane fuels

Well obviously you’re not going to control for your dependent variable, that’s the entire point of the study, but they’ve controlled for other health problems. If someone were decompnsated to the point of being unable to pick up prescriptions that would be reflected in their other medical problems. This is partly why psychiatric conditions can lead to physical illness
