Hydrogen fuel cell technologies are humming along but still pricey. @washuengineers.bsky.social 's Gang Wu has been working on a way to make use of iron components to replace precious metals, which could bring fuel cell tech costs way down. source.washu.edu/2026/02/maki... #ChemSky 🧪 #EnergySky
Making hydrogen fuel cells ‘less precious’
Engineers at Washington University in St. Louis are working to bring stability to iron components instead of using more expensive precious metals in fuel-cell technologies.

There is no biological mechanism by which a vaccine would impact fertility, but if you are dead or chronically ill from #Covid, that certainly will affect fertility. 🩺
Among almost 60,000 women aged 18 - 45 in one Swedish county, #Covid #Vaccination did not affect the chance of getting or staying #pregnant.
I know of at least a dozen studies that have shown this, but this is by far the biggest! I spoke to @lizszabo.bsky.social

Can you imagine how advanced society would be if people like Ms. West, Roz Franklin, pioneering entomologist Charles Henry Turner, were allowed to thrive and so many others who never got a chance to even approach the collective endeavor of science. Imagine that world, and make it so. 🧪 #ScienceSky
No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition.

whoever figures out a way to bundle independent journalism subscriptions will be a hero
i know that this is an unpopular take, but everyone starting their own newsletter as a revenue stream is not a sustainable model for writing and reporting or for people who love and want to pay for media.
