If you need a bit of ocean in your day (and who doesn't?), here's me in full ocean-enthusiast mode, on the BBC podcast/videocast The Climate Question. Now available both as a video-podcast and good old-fashioned audio-only podcast:

How could/should/will we get around the cities of the future? A car for everyone is never going to work in a city, but once we go back to seeing the streets as places for people to get around (rather than "where the cars go") how could it all work? Cities and technology are constantly evolving, and so our city streets will too. For this week's Rare Earth, on air at 12 today and online afterwards, we talked to Chris Boardman, Stephen Potter and Karen Lucas about what the future holds. Listen here:

The nuts and bolts of our world are literally made from steel: furniture, tools, buildings, containers & more. But making all this steel produces 8% of our carbon emissions, so one of the pillars of a clean future is green steel. Can it be done? We find out, in this week's Rare Earth:

Useless private medical tests=bad. But I heard recently (as an eg) abt work on a clock accurate to 1 second in the lifetime of the universe, while (peri)menopause is still poorly researched. Data *would* help, if collected & analysed properly, directly benefitting 1/2 of us. Why aren't we doing it?

Still gutted about the news on a lack of specialist physics teachers. Storm in a Teacup has been translated into 21 languages, & is still in print 7 years after I wrote it. Clearly people ARE interested in the physics of the world around them and how it works. This should be for everyone.

It's incredibly disappointing to hear that a quarter of UK schools don't have a specialist physics teacher. It's essential that we can all see the basics of how the world works & it's fun to satisfy that very basic curiosity. Physics gives us all agency in a complex world.

Reading Rebecca Solnit & I love this:
""The remains of the swamp grass, the ferns ... turned into coal. And to this cemetery we intend to go, drag the dead out of their tombs, and force them to work for us." That language frames it as a zombie movie, a horror story, the dead come back to haunt us."

In 1860, the British Parliamentary Standard Candle was used as a measure of brightness. Hunting for spermaceti to make this & far more drove a huge expansion of whaling in the 17th & 18th centuries.
In Friday's Rare Earth, 40 years on from the global moratorium on hunting whales for profit, we looked back at whalers, the long term consequences, new science on whale communication and connection to their ecosystem & the global whale health today. Available online now:

Ocean hivemind, I have a question. 🌊 Does anyone know of any academics or conservation organisation doing research into Mola mola (ocean sunfish) in Europe? And especially in the UK? All the studies I can find seem to have finished.

Today's Rare Earth was on insects - how they're doing and how we really need to work with them.
Here's my favourite example of how much we take insects for granted: Cattle make wet soft dung but wombat/kangaroo dung is dry/hard, so when cows came Australia the native beetles couldn't cope.
Since there was no fast way to recycle it, cow dung piled up for months/years. A decades-long project brought in foreign dung beetles so fields weren't covered in poo. A similar recent project had the strapline Beetles with Benefits.

Shoutout to all UK ocean scientists! This third FMRI podcast is the most interesting so far - really getting into the details of what the future could look like. This is going to affect ALL of us, so please do listen to the podcast and have your say. The fourth episode will be focussed on responding to your thoughts (we've got a bunch already but more is better), so do send your ideas, concerns, questions and comments!
This is also for anyone who uses UK marine research infrastructure - geologists, atmospheric scientists, polar scientists etc. Please do help spread the word, and feel free to post about your responses to the issues in the podcast - the aim of this is to stimulate discussion.

"Data product" is science language for a processed dataset that is organised, checked and ready for sharing. This announcement from the USA's National Oceanic and Atmospheric Adminstration means they're ending snow/ice data sharing. Globally critical data streams on the polar regions will just stop.
https://nsidc.org/data/user-resources/data-announcements/user-notice-level-service-update-data-products
And this is Ralph Keeling himself talking about the implications of NOAA being effectively shut down on global monitoring of CO2. Note that it's the global intercalibration of sensors that is at stake, not just someone making a measurement somewhere.

So much of the destruction in the USA is away from the spotlight at grass roots level. But the foundations of a modern society are being smashed. The National Science Foundation has just stopped awarding new grants and funding existing ones. That effectively means that work on all existing NSF grants has to stop immediately. Universities are telling researchers to stop spending on those grants right away. That's jobs and progress and opportunity just being eradicated.

It's a beautiful sunny morning in Berlin, everyone is walking to their local bakery or walking dogs, and the streets are completely clear. But there are cars everywhere, parked. The public transport here is so good, and people use it, but the cars sit around like the ghosts of a gridlocked past.

It's taken me a while to finish The Dawn Of Everything - it's 525 pages long and quite dense - but it was totally worth it. It reexamines history by looking at the many periods (the majority?) when there *weren't* kings, empires & hierarchical societies, questions a lot of assumptions about who was in charge, and suggests we're asking the wrong questions about our past. Highly recommended for anyone interested in how societies could and should be organised.

In today's Rare Earth on concrete, I somehow omitted my favourite thing about it:
To make concrete you need cement, which needs limestone. And the calcium in limestone was all collected by tiny sea creatures, building their shells atom by atom from the water around them. So the calcium in every single bit of concrete has passed through a sea creature. We only have skyscrapers because of marine life.

Today's Rare Earth (on air at noon) is all about concrete. We associate it with solidity and reliability, but also with being the scourge of the natural world. It has a huge environmental cost, so what does the future hold? And what might a concrete-free world look like?

Science types out there... I'm sure I have seen a demonstration of the poor tensile strength of concrete where you hit one side of a concrete block with a hammer and then a chip falls off the other end because that's where the reflected wave is first in tension. But I can't find a video of this online. Have I made this up? Does anyone know where I might find a video of this if not? Obviously google etc isn't getting me very far. Any ideas?

Chemists often complain the public mistakenly thinks chemicals=evil
But when you see the self-described "chemical industry" fighting reasonable regulation of 1000s of substances they make but don't explain to the public, many of which *do* spread invisibly and cause harm, I think this is on them.

I love this, from Elif Shafak, & it's what I need to hear at the moment:

The world is complicated, but I think the great challenge of our time is simple to express:
To learn how our natural life support systems work (our planet and our own bodies), to understand that they are complex and should be treated with respect, and to work with them rather than against them.

It's hard to say this, but science (& research more generally) is just being **stopped** in the US right now. This is just one university, losing nearly a billion dollars in project funding pretty much overnight. That's people's jobs, and the research that could save lives.

Was it Cory Doctorow who noted that the only way to stop a system being corrupted is to design it to be impossible to corrupt from the outset? AI involves surrendering a HUGE amount of power, and expecting no operator ever to surrender to the temptation to tweak it for their own benefit is ludicrous

The National Science Foundation funds a huge amount of science in the US, and this appeared on their website 7 hours ago (at https://new.nsf.gov/executive-orders )
This is telling people to stop work on existing grants if the work might touch on equality or diversity considerations (keep reading down).
I’m pretty sure that every grant application had to have a section on how those considerations were being addressed. This is mindblowingly disruptive and destructive.

Ocean research peeps, especially any of you who study animal movement, I've got a question for you. I've got data from the Labrador Sea in Nov/Dec that appears to show lots of swimming creatures(?) that comes upwards in the water column (from below 15m to about 10m) when it's daylight and disappear back down at night. It's definitely correlated with light (not there on completely overcast days), and it's definitely movement (ADCP scattering that's not at the bulk water velocity). What's weird is that it seems to come up during the day. Has anyone got any idea what that might be?

My favourite discovery in The Golden Mole: a whole new meaning to a house-moving chain. Hermit crabs that find a potential new shell that's too big wait next to it, & as others arrive they line up in size order until there's one who can take the big new shell. Then everyone upgrades.

Wow. I knew the Amazon river was big, but I just looked it up properly. It's 18% of GLOBAL outflow from all rivers to the ocean, five times bigger by volume than the next biggest river. The Amazon basin is about 5% of all the land, so it really is disproportionately wet. Impressed.

The problem with a lot of ocean "exploitation" is that it's like mining a human for calcium. Yes, a human body contains ~1kg of calcium, and you could take it out, but it's already *doing* quite a lot of useful things, and the human has far more potential to help you if you leave the calcium alone.
