There's only one perfect photo for this year's Earth Day, and it's this one that the Artemis II crew took. Happy Earth Day.

Sustainable laboratories: Recovering metals How to scavenge platinum group metals from laboratory waste

‘This project has made me more conscious of how we perform chemistry in a lab & it’s really made me think about how I can transform my workflow,’ says catalysis chemist Shiao Chow.

Runs on Aussie sunshine ☀️

No fuel stops. No price shocks. Just charge at home and drive.

This isn’t a drivetrain swap, it’s a system flip. From imported oil to rooftop energy.

Once the fleet scales, the economics break fast.

Cost always wins. #Bettrification

Anyway, waternotcoal.ca is out collecting signatures for the petition.

If you care about not having poisoned drinking water basically anywhere in Alberta, you need to sign this.

oh this is just 1920s style futurism. which is basically to say proto-fascism. it’s not even trying to conceal what it is. it’s a duck.

This is a well-documented pattern in medical research and reflects systemic gender bias in pain assessment and treatment.👇

God(s) grant me the serenity to deal with my University's IT Services.

The courage to deal with them one more time.

The wisdom to stop wishing they would be understanding and caring and transparent in their dealings.

A new review examines the role of endophytic microorganisms in medicinal plants, emphasizing their ability to enhance plant stress resistance and produce secondary metabolites with significant pharmacological potential. 🌿

How do you study microplastics when they’re everywhere?

Microplastics are everywhere, which makes studying them all the more difficult. Labs are doing all they can to be plastic-free but have few common protocols. Read more: cen.acs.org/analytical-c...

Low-cost, energy-efficient process shows potential for electrochemical propene production Reaction makes use of specially designed metal oxide-ionic liquid catalyst

Researchers who developed an electrochemical propane dehydrogenation process suggest that it could be economically competitive with the thermal process that is used widely in industry.

Pretty obvious.

can we do adobe next?

Artemis II crew enters moon’s ‘sphere of influence’ ahead of historic flyby Astronauts on Nasa’s Orion capsule made transition about 39,000 miles from the moon, meaning they feel its gravitational pull more strongly than that of the Earth The four astronauts on Nasa’s Artemis II mission have entered the moon’s “sphere of influence”, where its gravity has a stronger pull on the spacecraft than Earth’s. The crew made the transition, four days, six hours and two minutes into the mission, when about 39,000 miles (62,800km) from the moon, and 232,000 miles (373,400km) away from the Earth. The next key milestone will be the trip later on Monday to the far side of the moon, venturing deeper into space than any humans before. Continue reading...

Artemis II crew enters moon’s ‘sphere of influence’ ahead of historic flyby

Looking through one of the four windows of the Orion spacecraft, a tiny crescent Earth is illuminated against the blackness of space and grows smaller as the crew journeys closer to the Moon. Part of the window edge is visible; the rest is darkness. [Alt-text slightly revised from ESA/NASA version]

This planet — with all its troubles — is worth caring for.

That should be our single purpose, as a species: To be stewards of this magnificent world, ensuring it thrives long into the future.

ok so i know i expressed some ambivalence about people who insist journalists should never use AI for anything but let me be very clear and on the record: this is a shanda and not journalism, not anything

Firing Cabinet members and generals won’t make the Iran war go well.

The reasons it’s going badly are structural and geographic. Not hard to see in advance, and widely warned about.

But those warnings came from experts, and were dismissed by leaders who insist reality isn’t real if they say so.
