Similar to this, though I've also read of proposals to release dyes in the polar gyre to reduce reflectivity.

Light isn't a limiting factor for most marine biomes that rely on photosynthesis.

Just some considerations for conversation -

1. Applications to increase waters reflectivity and prevent the penetration of some wavelengths have been considered to reduce solar absorbance, to reduce heating.
2. The square footage at hand here is vanishingly small compared to the square footage of the ocean. You could easily just put these out to sea over deadzones, where ecosystems aren't reliant on light anyway.

Not sure, but for comparison, rovers on Mars often experience failstate conditions when dust covers their solar panels over the course of a few months to a year or so. There have been instances of small twisters rolling past or over a rover and clearing off the panels.

So the deposition is probably not more than a few mm annually, if that, and maybe the material of the sample holders is dust repellant or something, but "being covered by dust" is most certainly something to consider.

You are correct that the dust storms on Mars are moving less material than dust storms on Earth. That doesn't mean things left on the surface cannot be buried. It's not a bad question, and doesn't deserve your knee jerk shitty attitude.

I think it's interesting that dogs have adapted to fulfill emotional needs as well as hunting and guard keeping needs.

But yeah, look at... Pollinators for example as coevolution. A lot of plants lost the ability to reproduce without an insect being bribed to do it for them. And that got creative and weird.

Hi, I am a clinical trials results analyst.

All clinical trials do not require a placebo control. Many trials are looking at "how something changes from baseline", in which case we already have baseline data. Additionally many interventions are "how is this in addition to standard of care", so it's not like people are getting no intervention.

This is a common misconception that every single clinical trial must be double blind placebo controlled. We have robust historical data on things.

This is approximately what my last job search looked like. I have a PhD and six years experience in my field. I had a couple bait and switches, a couple absolute lowball offers, and one offer that after no joke, 8 separate interviews, they offer me the position and tell me that they've reconsidered WFH and expect me to move within 3mo! They compromised to "delay start date by 9 months".

Job hunting sucks.
