In a recent #SETILive episode, host Beth Johnson spoke with UC Santa Cruz postdoctoral researcher Dr. Artem Aguichine about his work modeling the interiors and atmospheres of steam worlds, a class of water-rich exoplanets wrapped in thick, high-temperature water vapor. Thanks to new spectra from the James Webb Space Telescope (JWST), these once-theoretical worlds are rapidly becoming an observational reality.

Who really won when Bergson and Einstein debated time?

Henri Bergson and Albert Einstein fundamentally disagreed about the nature of time and how it can be measured. Who was right?

#EPA Scientists Said They Were Pressured to Downplay Harms From #Chemicals. A Watchdog Found They Were Retaliated Against.

Three reports issued by the agency’s inspector general detailed personal attacks suffered by the scientists — including being called “stupid,” “piranhas” and “pot-stirrers” — and called on the EPA to take “appropriate corrective action” in response.

This is the country that wants to compete with China. Two-thirds of voters now believe a college degree is a financially ruinous trap, a complete reversal from a decade ago. The US is actively dismantling its own pipeline for advanced skills and knowledge while complaining about falling behind. The self-sabotage is frankly impressive.

We grew a forest WITHOUT planting a Single Tree

Across Africa, forests are disappearing faster than anywhere else on Earth. But hidden under the surface, a solution is waiting: Underground Forests. Root systems that are still alive and with the potential to restore huge areas of barren landscape.

My #Introduction.

I talk about life in #CambridgeMA and #Boston, #engineering, #science, #radios (#SDR, #HAM, #LoRa, #MeshCore), #pinball, #film, retro computers/video games, and more.

I collect #art, #LaserDiscs, study #horology, visit museums (The Met, MFA, Harvard Art #Museum) and support my local #library.

I read #poetry and books on #architecture, #design, and #urbanism.

I walk or take public #transit everywhere.

I practice #permacomputing and self-hosting, running #BSD where I can.

My handmade Doctor Who scarf that I got as a birthday present a few years ago is getting some air 😁

American bacteriological chemist, food scientist and refrigeration engineer Mary Engle Pennington was born #OTD in 1872.

She was a pioneer in the preservation, handling, storage and transportation of perishable foods and the first female lab chief at the U.S. Food and Drug Administration. She was awarded 5 patents, received the Notable Service Medal from President Herbert Hoover and the Garvin-Olin Medal from the American Chemical Society.

How the Telegraph Went From Semaphore to Communication Game Changer

Samuel Morse was an artist by trade, but to the world he’s best known for connecting the dots —and dashes— that forever changed the way we communicate

#OTD in 1846.

William T. G. Morton administers ether anesthesia during a surgical operation, by the use of inhaled ether.

A month after this demonstration, a patent was issued for "letheon", although it was widely known by then that the inhalant was ether. The promotion of his questionable claim to have been the discoverer of anesthesia became an obsession for the rest of his life.

A new moon. An interstellar comet. An intriguing biosignature. An advance in signal detection. And so much more!

Across the SETI Institute, this year brought remarkable progress in our search for life and our understanding of the cosmos. We developed new techniques, expanded our datasets, and made discoveries that will shape the work ahead in meaningful ways.

JWST has delivered one of the most detailed looks yet at how moons form around young planetary bodies. In a recent SETI Live conversation, host Dr. Moiya McTier spoke with University of Zürich research fellow Dr. Gabriele Cugno and Carnegie Institution for Science postdoctoral fellow Dr. Sierra L. Grant about their analysis of CT Cha b – a distant, planetary-mass companion surrounded by a compact moon-forming disk.

Comet 3I/ATLAS passed through the inner solar system on a one-time trajectory, entering a brief but consequential observational gap. During this interval, the object moved behind the Sun from Earth’s perspective.

In a recent #SETILive discussion, Beth Johnson and Dr. Cynthia Phillips discussed how an instrument built for a very different target was rapidly repurposed to study one of the rarest objects ever detected in the solar system.

Lise Meitner died #OTD in 1968.

She is known for her part in the discovery of nuclear fission. Among physicists she had been known for many years as one of the early pioneers in the study of radioactivity. Einstein nicknamed her ‘the German Madame Curie’.

Oops,

Pocket mammoths really existed. I only knew them from Elder Scrolls Online:

But according to @wikipedia, they also existed on Crete:
