Les conseils sont bons, mais je trouve que les Iraniens sont super stoïques.
This is how serious the situation is:
Iranian state media is broadcasting advice to its citizens on how to survive a US-Israeli NUCLEAR ATTACK
☢️ Do not look at the intense explosion light, take shelter behind a barrier, lie on the ground, and cover your head and face.
☢️ After the blast wave passes, enter the nearest building; do not stay to watch or take photos, do not take shelter inside a car.
☢️ Turn off ventilation, get yourself to a central part of the building where there are no windows and exterior walls.
☢️ Wash with lukewarm water and soap, and use regular shampoo without conditioner. If showering is not possible, clean your face, hands, and exposed skin with water or wet wipes.
☢️ Use bottled water and packaged food, and prepare to stay in the shelter for at least 24 hours; if fires break out in the building or there is a risk of its collapse, move to a safer shelter.
☢️Do not assume the environment is safe after the first 24 hours; follow official announcements and emergency broadcasts for the safe evacuation route.

All 5 fundamental units of life’s genetic code were just discovered in an asteroid sample
theconversation.com/all-5-fu…
A new study reveals all five fundamental nucleobases – the molecular “letters” of life – have been detected in samples from the asteroid Ryugu.
Asteroid particles offer a glimpse into the chemical ingredients that may have helped kindle life on Earth. The Ryugu samples were returned from space in 2020 by Japan Aerospace Exploration Agency’s (JAXA) Hayabusa2 mission.
In 2023, an international team reported they had found one of the nucleobases in these samples – uracil. Now, in a study published in Nature Astronomy today, a team of Japanese scientists has confirmed all five nucleobases are present in this pristine asteroid material.
This means these ingredients for life may have been widespread throughout the Solar System in its early years.

I updated my substack on NATO nuclear aircraft dispersal plans with some excellent quotes from a 1964 evaluation of the shortcomings of NATO's deterrence and defence plans:

Des photos que j’ai poncé dans les livres et sur le net, en étant gosse. Je me disais « la place a l’intérieur doit être énorme! »
En fait, pas vraiment: un typhoon, c’est deux coques de SNLE type Delta côte à côte. (Comme un catamaran).
Bon, ça reste (très) très grand.

Scrutin majoritaire équitable. On n'a pas assez de députés pour autre chose.

Fun fact : Pour ceux demeurant dans les latitudes sub-tropicales, il se peut que vous observiez un "météore" très brillant, visible en plein jour. Le satellite Swift (observations gammas) entrera dans l'atmosphère après 22 ans de mission. L'incertitude est...
