    By any standards this morning’s climate event was rather strange. No questions, no answers on key points, no mention publicly of the sacking of Claire O’Neill. Many experts here left bemused and not a little worried about

    We need to get a better handle on transmission dynamics and risks. continued comparisons to SARS might not be helpful. We'll see. I hope I am wrong. And I probably will be! Tomorrow the evidence might be: little H2H, mild/asymptomatic rare and when it occurs they don't transmit.

    Interesting that many views moving towards being bigger pandemic (then endemic)risk than previously thought. If you have reasonable H2H and mild/asymptomatic infection with transmission then this seems almost inevitable; or at least makes infection control far less easy

    As has been pointed out R0 does change (down) as control measures etc, put in place But key is who transmits... If you're into R0 for Mers/Sars then here you go:

    Also in 2019, Alan Jamieson 🏴󠁧󠁢󠁳󠁣󠁴󠁿 dived with Vescovo to the Sirena Deep of the Mariana Trench, which is only just a tad shallower (10.7 km) than the Challenger Deep. So now 8 people have been to >10.5 km deep - that's two-thirds the number of people who have walked on the Moon.

    60 years ago today, Jacques Piccard & Don Walsh became the first humans to reach the deepest part of the ocean... ...the Challenger Deep of the Mariana Trench, which is more than 10.9 km deep (nearly 7 miles down)

    SpaceX are about to launch the next 60 of their mega-constellation of satellites, including the first which are blacker to reduce brightness in the night sky. Amateur observations and estimates of brightness are much needed.

    In case you missed it, the Mission Jurassic online piece by my colleague is amongst the best long reads of 2019 . My small contribution were the video inserts but you can see the full TV package here -
