Not sure what people are interested in CO2 sensors for, but I use them as a proxy for ventilation in indoor spaces, which is then a proxy for covid risk. It won't tell you if the air is being filtered (need MERV13 or better), but a lot

Pretty impressive, if true that it can stop infection, and potentially then transmission. Nasal vaccines have the ability to do this because of the potental for neutralizing activity along the nasal muscosa. They make the claim so we'l

I love to see Hacker News geeking out on heat pumps and that this is currently on top of the home page! Don't forget that this community has an outsized influence on the world as early adopters and innovators.

Good math, the nickel per hectare target in the field and in the literature through cultivars is around 400 kilograms per hectare (.400 tonnes per Ha). We are using natural serpentine soils that have previously been farmed and are idle now

I can definitely clarify that further, but to restate it, there are new sources and new technologies that can allow us to meet the requirements for the transition. For example, the Salton Sea contains enough lithium dissolved in brines unde

We don't need to go to the ocean for metals. There are new technologies that can recover metals much less destructively from "unconventional resources" that are already exposed or naturally exposed. And some of those mienral

This is insane again as it was just found that an infection lowers your IQ by 3 points (2 big recent studies)*. The average person now has over 3 infections to date. We aren't even far enough in the research to understand the compound

The RSS feed sits on the side of screen or appears on hover. It is like a summary of headlines of what is going on in your inbox. I guess it depends on your use case if you reach inbox zero daily. Unfortunately, I don't go to inbox zer

Their "The Feed" is a feed of the newsletters which is interesting. I guess what I am thinking is more along the lines of if those were in a more condensed feed with a TL;DR type summary above it. I am also thinking of a UI that i

The point is more generally to allow you to go longer without having to go to your inbox and/or to be able to turn of notifications for email. The RSS comes in quietly and the body and preview is an AI summarized. Often times I'm

Is anyone out there looking for an RSS style feed of their email? In a sort of non-disruptive scrolling mechanism... possibly with AI summary of the emails. This would not replace your inbox, but allow you you to not have to go into your in

This study is about the amphetamine stimulants methylphenidate, dextroamphetamine, and the eugeroic (wakefulness agent) modafinil, and not about nootropics. Though the term smart drug can be inclusive of all of them... Real smart drugs = no

Sibelco's Aheim mine essentially supplies a large part of the world's olivine today. It is located in a Fjord with its own port. The transportation distance is very small. See their website here: https://www.sibelco.com

Actually, this incorrect, soils naturally acidify through nutrient loss (e.g. natural minerals) and the breakdown of nitrogen fertilizers. And soil have been amended with limestone (and volcanic soils) for a very long time. In fact, terrest

The CO2 storage is inorganic as bicarbonate dissolved in seawater and is considered permanent (60,000-100,000+ years). This process occurs as rocks weather and release magnesium or calcium cations. The "enhanced rock weathering" (
