Good to escape the distortions of The Algorithm long enough to note that, outside this ridiculous echo chamber, the population has a high and increasing level of trust in academics and scientists, and no time for social media influencers. 🧪 (www.ipsos.com/en-uk/ipsos-...)

Serotiny means that the seeds are stored on the mother plant, that they are retained 1+ yr (up to 10+ yr), & that high temp. (usually from fire) is involved in the release of the seeds. 📷: Pinus pinaster. Note 2 generations of seed cones on the shoot. #Pinaceae #serotiny #Botany 🌾🧪🌱
Photo of a pine branch with older, mature, closed cones and younger, smaller cones. The younger cones are at the distal end of the shoot. Photo by Scott Zona CC BY-NC 2.0.

NASA astronaut & biochemistry researcher Peggy Whitson was born #OTD in 1960. Whitson holds the US space endurance record. Cumulatively, she spent 695 days in #space--the equivalent of a hypothetical round trip to Mars. First woman NASA Chief Astronaut, 2009. (1/2) #WomenInSTEM #AstronautEnvy 🚀
Formal portrait of now-retired NASA astronaut Peggy Whitson in her full white spacesuit with American flag and NASA insignia patches. She stands confidently holding her helmet, smiling warmly at the camera. The suit includes the Extravehicular Mobility Unit backpack, gloves, and detailed mission patches, with American and NASA flags in the background.
Color photograph of Peggy Whitson floating weightlessly inside the International Space Station during the Ax-2 mission. She is smiling broadly while posed in a dynamic zero-gravity position with one leg bent and arms extended, wearing a black and blue Ax-2 branded jumpsuit with the Axiom Space logo and mission patch. Earth’s blue atmosphere and clouds are visible through the large window behind her, highlighting her joyful expression in orbit.

Energy geeks, please put on your quibble hats, prepare your hair splitters, and get ready to pick some nits! What do you think about this slide from my upcoming lecture on solar energy?
Title: (Almost) all energy on earth is solar energy hydro ←solar (via the water cycle) wind ←solar (via hot air rising) biomass ←solar (via photosynthesis) fossil fuels ←biomass (via rotting underground) ←solar but nuclear x←solar geothermal ←nuclear (via reactions underground) and solar ←nuclear so really, all (?) energy on earth is nuclear energy

Oil geologists, if there are any on here: was the oil at Spindletop Jurassic in age (I know the salt dome it came out of was) or did it seep up from the Paleozoic? I haven't been able to find a clear answer on this, and I'd really like to know!

Valerie Thomas spent 30+ years at NASA helping revolutionize how we see images from space & our own world. #WomenInSTEM Managed the development of the first image-processing systems for the Landsat program allowing satellites to send the 1st multi-spectral pictures of Earth back to scientists.(1/2)
Portrait of Dr. Valerie L. Thomas, the pioneering Black NASA scientist and inventor, smiling warmly at the camera. She has shoulder-length wavy gray hair, wears thin gold-framed glasses, gold hoop earrings, and a light gray herringbone-patterned blazer over a white top with a small pin on the lapel, standing confidently against a neutral gray background.

SO COOL!! Sulphur taking the shape of a pinecone!! It replaced the original material. #MineralMonday #GeoscienceBluesky ⚒️🧪
Pinecone made up of sulphur, so it’s a pale brown colour. It sits on a clear plexiglass plinth on a white background. At the Field Museum.

We're going to have an entire class of people who try to map Elon Musk's obviously incorrect timelines into truth in the same way that there are people who really try to map time intervals in the Bible to time intervals as humans understand them, aren't we?
X Elon Musk @elonmusk For those unaware, SpaceX has already shifted focus to building a self- growing city on the Moon, as we can potentially achieve that in less than 10 years, whereas Mars would take 20+ years. The mission of SpaceX remains the same: extend consciousness and life as we know it to the stars. It is only possible to travel to Mars when the planets align every 26 months (six month trip time), whereas we can launch to the Moon every 10 days (2 day trip time). This means we can iterate much faster to complete a Moon city than a Mars city. That said, Space will also strive to build a Mars city and begin doing so in about 5 to 7 years, but the overriding priority is securing the future of civilization and the Moon is faster.
