Per- and polyfluorinated alkyl substances (PFAS) have been found to contaminate the global environment and have been implicated in a wide range of health problems. But the tough carbon-fluorine bonds in the compounds resist being torn apart, leading to expensive remediation schemes that rely on powerful chemicals and high temperatures and pressures. Today, two groups report in Nature the discovery of catalysts that could offer a cheaper way to clean up the chemicals. When energized by light, the catalysts break down a wide range of PFAS compounds at low temperatures and ambient pressures.

Hashtags good.

Why can't it stay liquid?

[–] CrimeDad@lemmy.crimedad.work 4 points 3 weeks ago

Well, the water is necessary for for life support and needs to be sourced somehow anyway. It kind of sets a minimum crew and passenger capacity if you want to make the most use of your shielding water.

Water doesn't have to be a liquid, but don't actual spacecraft typically contain liquids during wall of those cases? What do you mean?

I don't think it works that way. The water slows down the neutrons so that when and if they get to you they don't have enough energy to hurt you. The radiation doesn't contaminate the water any more than a microwave oven does.

Since the astronauts need water to survive, why not line the spaceship with reservoirs of it to provide the shielding? Or does water not block space radiation well enough?

Trying again doesn't necessarily mean trying again right away.

They could have tried again with another booster and landing pad.

If the developers could fix search, it would go a long way in improving Mastodon.

Never post your resume or sign up for LinkedIn in the course of a job search? Never use a dating site? Never buy a domain? Never pay property taxes? Never go to court? I see your point, but never revealing your info online isn't realistic or even a choice for most people.

 

I wish I got to do fun little projects like this at my job. Anyway, this proof of concept shows that hydrogen would be a great alternative to propane and natural gas for cooking. Hat tip to @hypx@mastodon.social.

Solar project to destroy thousands of Joshua trees in the Mojave Desert

It's crazy to me that a destructive photovoltaic solar project like this one is considered reasonable, but a new nuclear power plant within or adjacent to a city is beyond the pale.

Just build a replacement nuclear power plant and reuse the water. Right?

 

Please suggest relevant communities to share these sorts of nonsense products marketed with unfounded health claims.

#Hydrogen infused water?

I am of course pro #HydrogenEconomy, but this sort of nonsense is just too much.

Well this is a bummer.

Installing Lemmy with @yunohost@mastodon.social was probably the easiest way to get it up and running. Hopefully it's not abandoned.

Is self-hosted enough to avoid push notifications going through Apple and Google servers?

 

I have mostly enjoyed using GnuCash for desktop and GnuCash Android for years, but the Android version hasn't been updated in a while and I noticed that it isn't even available in the Google Play store anymore (or F-Droid, for that matter). There's a different GnuCash Android app available, but it's a different developer and it looks kind of bad. I'm concerned that if I get a new mobile device and/or upgrade the version of Android I'm running, I may lose access to the app, which would be a huge bummer. To avoid that, I would like to find a good GnuCash alternative ahead of time. Is anyone aware of a self-hosted solution for double entry accounting that will import GnuCash files and can handle non-currency assets as well as GnuCash for desktop does?

So far, it seems like Fava and Beancounter might do the trick, but I'm not sure.
