A welcome, if belated, awakening to the disconnect between Musk's actions and the stated values of the Royal Society?

A recent interruption in the 6-year oscillation in length-of-day SUMMARY. Intradecadal variations in the length-of-day ($\Delta$LOD) can reveal changes in angular velocity interpreted as due to Earth’s core. Previous stu

🌍New Paper Alert🕰️

Our paper "A recent interruption in the 6-year oscillation in length-of-day" is finally out in #GJI @rasjournals.bsky.social.

Did you know that the length of a day changes every day?
We use this information to look at Earth's core.

It turns out that we are all wrong and earth's magnetic field is not generated by dynamo action in the liquid core...

But I think the MHD equations would beg to differ...

UC Berkeley shares 160 names with Trump administration in ‘McCarthy era’ move Prominent professor Judith Butler among students and faculty investigated for ‘alleged antisemitic incidents’

Names include international students, lecturers and part-time faculty, Judith Butler says: “The consequences of this compliance could be terrible for a lot of people’s lives, most of whom are much more vulnerable than I am. They can suffer deportation, expulsion, job loss, harassment, surveillance"

Must admit I'm a bit sad that the Royal Society consider their fellows to be "mid career". Kudos to these amazing people, but what hope for the rest of us in obtaining these "mid career" fellowships..

If you're at #IAGA in Lisbon and want to chat about earths magnetic field and dynamo, please stop by my poster!

So there has been a lot of back and forth about this. I think there are two potential issues here: 1. The increased bureaucratization of HE, and 2. Senior management led "initiatives".

My profound thanks to all 3494 members of the scientific community who signed my open letter calling on the Royal Society to stand up for its values in respect of concerns raised by the statements and actions of one of its fellows, Elon Musk. occamstypewriter.org/scurry/2025/... 1/2

I will keep the letter open until 3rd March, the date of the meeting called by the Royal Society to discuss principles around the public pronouncements and behaviours of its fellows.

So one more week to add your voice to the call for the RS to stand up for its values.

Now over 2700 signatories and still rising. Please keep sharing.

Interested in the Formation and Evolution of Earth's solid inner core?

Of course you are! Well you're in luck, because Fred Wilson et al. read a load of stuff and succinctly summarised it here: rdcu.be/d9ALQ

Wonderful news!

This from Magali Billen, UC Davis:

Dr. Don Turcotte passed away yesterday. He was 92 years old.

he was surrounded by family. His granddaughter had wanted to read something to Don in the hospital so his son suggested “Geodynamics” - she was reading to him in his final moments. ⚒️

Been watching The Madness on Netflix and it just feels like having a really recognisable beard and refusing to cut it is not the best strategy when the whole of America is looking for you

Probably our last attempt for a while... And little has changed since your first paper Jenny!

A two-phase two-component slurry model of the F-layer at the base of Earth's core We present a new two-phase two-component slurry model of the F-layer at the base of Earth's liquid outer core. Seismic observations indicate that the …

More photos of random runs around the Yorkshire winter wonderland while it lasts!

What better way to ease into the new semester than a run through this little winter paradise. Might almost be ready to open Minerva

Tonight my wife introduced me to what she called the "sweeping look", which seems to be a quick glance around a room that ignores all the things I find important

After a beautiful Christmas in Rome I feel equally ready to take on the new semester and start a new life eating and drinking in the sun

This week is already an excellent week because it has not involved a grant rejection, paper rejection, or stolen laptop (most of which had happened by this time last week!)

Can't beat a bit of exploring in the snow!

Ok, now I've accepted that the old place is rubbish I'd better start posting here. So here's a view of beautiful snowy Saltaire from two days ago

EGU announces the 2025 awards and medals! The European Geosciences Union is honouring 49 people at all stages of their careers who have made substantial contributions to the Earth, planetary, and space sciences.

Many congratulations to Paul Tackley, Professor of Geophysical Fluid Dynamics, for being awarded the 2025 Arthur Holmes Medal and Honorary Membership by @eurogeosciences.bsky.social for achieving an exceptional international standing in solid Earth geosciences.
