#PPOD: ESA's ExoMars orbiter caught a close-up view of a huge crater on Mars. This remnant of an ancient impact is just one of the many scars asteroids have inflicted upon the Red Planet. Water, volcanoes, and impacts from asteroids shaped the Martian surface in the ancient past, but the preservation of this impact is remarkable. The crater is located in Utopia Planitia and is about 8 km in diameter. Credit: ESA/TGO/CaSSIS
Most of us will undergo a procedure requiring a general anesthesia at some point in our lives. Although it’s one of the safest medical practices, we still haven’t grasped what the anesthesia does to our brains. A new study, however, sheds some light on why the drug seems to only affect specific parts of the brain. Science Alert explains: https://flip.it/SV41nP #Science#Health#Medicine
New Review Essay on @lmesseri tremendous new book, ethnography & tech, social hopes, & false dreams of tech solutionism. Also discussing work of Andrew Brock, Zeynep Tufekci & Kelsie Nabben on Black Twitter, Twitter & ethnographies of DAOs.
Travis Rieder's new book, Catastrophe Ethics, "aims to advise the well-intentioned, morally anxious & philosophically curious person" confronting the questions about whether our personal choices about the environment, technology, & justice matter.
En ce moment je lis le roman Tobie Lolness écrit par Timothée de Fombelle et illustré par François Place.
Ce livre peut être lu dès 12 ans solo mais vers 10 ans vaut mieux être accompagné pour la compréhension. Je le lis à la base pour le travail mais bon..
Bref, je le conseille vivement aux grands comme aux petits, je vais développer un peu pourquoi.
May has been an exciting month for our Sun. A barrage of solar storms and coronal mass ejections created the strongest solar storm to reach Earth in two decades — and possibly one of the strongest displays of auroras in the past 500 years. NASA.gov tells us how the agency tracked it, and the images and videos are astonishing, too. https://flip.it/VBUyCn #Science#Space#SolarStorms#Aurora#NASA
Researchers have found, in mice, that a strain of gut bacteria – Ruminococcus gnavus – can enhance the effects of cancer immunotherapy. This suggests a new strategy of using gut microbes to help unlock immunotherapy’s untapped cancer-fighting potential https://www.byteseu.com/120683/#Science
It’s surprising how many animals can act weirdly human. From territorial chimps to extroverted orcas, Live Science points us to 32 such animals that demonstrate humanlike behavior. https://flip.it/WyuSD1 #Science#Animals#Humans
From a Wash Post article on evidence humans were in N. America earlier than previously thought. I myself have a mixed-feelings middle-ground view on peer review, but I'm in a very different field.
"The peer-review process is designed to help validate scientific claims, but Lowery argues that in archaeology it often leads to a circle-the-wagon mentality, allowing scientists to wave away evidence that doesn’t support the dominant paradigm. He says he isn’t seeking formal publishing routes because “life’s too short,” comparing this aspect of academic science to “the dumbest game I’ve ever played.”"
Austrian molecular biologist Max F. Perutz was born #OTD in 1914.
He is best known for his work on the structure of hemoglobin, for which he was awarded the Nobel Prize in Chemistry in 1962, sharing it with John Kendrew.
Using X-ray crystallography, Perutz was able to determine the three-dimensional structure of hemoglobin, which was a groundbreaking achievement in understanding how proteins function at the molecular level.
French physicist Jean-Pierre Christin published the design of a mercury thermometer using the centigrade scale with 0 representing the melting point of water and 100 its boiling point.

1112 authors for a space mission 🛰️ reference paper seems ... adequate 🤷🏽😯😁
We, the @ec_euclid will publish five main reference papers aimed at the astronomy community about the #ESAEuclid mission, the #Euclid instruments, both cosmology and other astronomy science possibilities, as well as the cosmological simulations used to test all procedures.
Available coming Tuesday, 23 May, 12:00 CEST (and on arXiv a few hours later). Stay tuned!
Coordination of 100 to 1000 co-authors is actually quite a logistical feat. For this the @ec_euclid has a dedicated membership and author database, to keep contact info and affiliations up to date, and to manage the author lists of already more than 100 publications.
The upcoming release this week has still required a lot of work behind the scenes.
