Donald Trump in Davos

Trump's speech is much longer than Carney's. He mentions his "enemies", does a lot of bragging about the US economy, tells some lies about green energy (and does some literal tilting at windmills, hilariously), says the usual BS about how the US "gave Greenland back" and now Denmark is soooo ungrateful, and some other oddities. But here's my favourite excerpt. Remember... he is in Davos. Which is in Switzerland. And Switzerland's president, by the way, is Guy Bernard Parmelin.

Here we go... Brace yourself.

Trump: "we put a 30 per cent tariff on Switzerland and all hell broke loose. They were calling, I mean like you wouldn’t believe. And I know so many people from Switzerland. Incredible place, incredible brilliant place. But I then realized that they’re only good because of us.

... And the I guess prime minister — I don’t think president — I think prime minister called. A woman. And she was very repetitive.

She said, ‘no, no, no, you cannot do that, 30 per cent. You cannot do that. We are a small, small country.’ I said, ‘yeah, but you have a big, big deficit. You may be small, but you have a big deficit than big countries.’

She said, ‘no, no, no, please, you cannot do it.’ Kept saying the same thing over and over. ‘We are a small country,’ she said, but you’re a big country in terms of… and she just rubbed me the wrong way, I’ll be honest with you.

And I said, ‘all right, thank you, ma’am. Appreciate it.’

‘Do not do this.’

‘Thank you very much.’ And I made it 39 per cent.

And then all hell really broke out. And I was paid visits by everybody. Rolex came to see me.  They all came to see me. But I realized and I reduced it because I don’t want to hurt people, I don’t want to hurt them.

... And as she said, "it’s a small place" and I realized with that, I don’t know, I was so, because she was so aggressive. And I realized in that conversation that the United States is keeping the whole world afloat."

Treatments for ADHD: beyond stimulants

If your child has ADHD or you're curious about its treatments, check out my piece for Nature.

https://www.nature.com/articles/d41586-026-00095-w

All brains are different. ADHD isn't a "problem", it's a variant in brain wiring. We can harness its advantages, or alter our environment to reduce the disadvantages. Along the way, we can also treat the symptoms that are making life hard. This feature is about that. 

Main messages:

- Stimulants like Ritilin and Adderall work really, really well: they are some of the most efficacious drugs on the market for ANY condition.

- These drugs improve all kinds of measures, not just the core symptoms of inattention, hyperactivity and impulsivity, but also self esteem, reduced car crashes, less criminal behaviour, etc. But they don't magically make your kid smarter (they don't necessarily do better on tests) and they might wear off after a few years of use.

- stimulants come with issues for some people (addictive qualities, misuse, anxiety) 

- There are other drugs available, notably alpha agonists, which a lot of people haven't heard of but can work just as well or better for some people.

- other innovative drugs are in the pipeline but none look particularly promising. Again, stimulants work REALLY well so they're hard to beat.

- what about non-drug options? You can stimulate or exercise the brain to build up the bits that need work in ADHD patients.

- exercise, meditation, talking therapy - none have been shown to work very well (but they probably help with other issues, like self esteem etc!)

- neural feedback (where you get a visual representation of what's going on in your brain, to help you direct blood flow etc to certain bits) also doesn't seem to work well, even though it sounds like it should work.

- neural stimulation (where you literally give tiny electric shocks to part of your brain from a headband) might work! It's early days so hard to say, and there's different types, but some of it might work.

One of the researchers I spoke to has ADHD himself and has never chosen medication... instead he drinks a lot of coffee, and lets his interest in his work, and his hyperfixation, help him to achieve great things. That story didn't make it into the piece. But it just goes to show... ADHD brains for the win.

Mark Carney's speech in Davos: Go Canada!

This is quite a speech... copying it here for the record. 

Everyone (including me) is applauding Canadian PM Mark Carney for being forthright and saying some things that needed to be said at the World Economic Forum in Davos. But I do wish he would use fewer words like "hegemon", and name some names (like Trump). Since some of this speech is in academic-ese, I have taken the liberty of providing some rough 'translations' in bold...


Below is the full transcript of the English parts of Canadian Prime Minister Mark Carney’s remarks.

It seems that every day we’re reminded that we live in an era of great power rivalry — that the rules-based order is fading, that the strong can do what they can, and the weak must suffer what they must.

[translation] The big boys (Trump, Putin et al) are fighting. The rest of us are gonna suffer. 

And this aphorism of Thucydides is presented as inevitable, as the natural logic of international relations reasserting itself. And faced with this logic, there is a strong tendency for countries to go along, get along to accommodate, to avoid trouble, to hope that compliance will buy safety.

Well, it won’t. So what are our options?

[translation] We're all cowering in front of Trump in hopes he won't hit us. This won't work.

In 1978, the Czech dissident Václav Havel, later president, wrote an essay called “The Power of the Powerless,” and in it he asked a simple question: how did the communist system sustain itself?

And his answer began with a greengrocer. 

[translation] Bear with me. I'm going to tell a story about a greengrocer so I sound like an ordinary dude. But it's a Czech greengrocer from 50 years ago, so... not that ordinary. 

Every morning, the shopkeeper places a sign in his window: “Workers of the world unite.” He doesn’t believe in it. No one does. But he places the sign anyway to avoid trouble, to signal compliance, to get along. And because every shopkeeper on every street does the same, the system persists — not through violence alone, but through the participation of ordinary people in rituals they privately know to be false.

Havel called this living within a lie. The system’s power comes not from its truth, but from everyone’s willingness to perform as if it were true. And its fragility comes from the same source. When even one person stops performing, when the greengrocer removes his sign, the illusion begins to crack.

Friends, it is time for companies and countries to take their signs down.

[translation] We gotta face up to the bully now.

For decades, countries like Canada prospered under what we called the rules-based international order. We join its institutions, we praised its principles, we benefited from its predictability. And because of that, we could pursue values-based foreign policies under its protection.

We knew the story of the international rules-based order was partially false, that the strongest would exempt themselves when convenient, that trade rules were enforced asymmetrically, and we knew that international law applied with varied rigor, depending on the identity of the accused or the victim.

This fiction was useful, and American hegemony in particular helped provide public goods, open sea lanes, a stable financial system, collective security, and support for frameworks for resolving disputes.

So we placed the sign in the window. We participated in the rituals, and we largely avoided calling out the gaps between rhetoric and reality.

This bargain no longer works.

[translation] No, really. We gotta face up to the bully now.
 

Let me be direct. We are in the midst of a rupture, not a transition. 

[translation] The world is really f^&k'd up

Over the past two decades, a series of crises in finance, health, energy and geopolitics have laid bare the risks of extreme global integration. But more recently, great powers have begun using economic integration as weapons, tariffs as leverage, financial infrastructure as coercion, supply chains as vulnerabilities to be exploited.

[translation] In case you missed it: Trump is the bully. (See how I put 'tariffs' in there)

You cannot live within the lie of mutual benefit through integration when integration becomes the source of your subordination.

The multilateral institutions on which the middle powers have relied — the WTO, the UN, the COP, the very architecture of collective problem solving — are under threat. As a result, many countries are drawing the same conclusions that they must develop greater strategic autonomy in energy, food, critical minerals, in finance and supply chains. And this impulse is understandable.

A country that cannot feed itself, fuel itself, or defend itself has few options. When the rules no longer protect you, you must protect yourself.

[translation] Buckle up, buttercup. Get your fists up.

But let’s be clear-eyed about where this leads. A world of fortresses will be poorer, more fragile, and less sustainable.

[translation] But don't do it alone. Team up. 

And there’s another truth: if great powers abandon even the pretense of rules and values for the unhindered pursuit of their power and interests, the gains from transactionalism will become harder to replicate.

Hegemons cannot continually monetize their relationships. Allies will diversify to hedge against uncertainty. They’ll buy insurance, increase options in order to rebuild sovereignty, sovereignty that was once grounded in rules but will increasingly be anchored in the ability to withstand pressure.

This room knows this is classic risk management. Risk management comes at a price, but that cost of strategic autonomy, of sovereignty, can also be shared. Collective investments in resilience are cheaper than everyone building their own fortresses. Shared standards reduce fragmentations. Complementarities are positive sum.

The question for middle powers like Canada is not whether to adapt to the new reality — we must.

The question is whether we adapt by simply building higher walls, or whether we can do something more ambitious.

[translation] Canada is totally up for teaming up. Who's with us?

Now, Canada was amongst the first to hear the wake-up call, leading us to fundamentally shift our strategic posture. Canadians know that our old, comfortable assumptions that our geography and alliance memberships automatically conferred prosperity and security, that assumption is no longer valid. And our new approach rests on what Alexander Stubb, the president of Finland, has termed value-based realism.

Or, to put it another way, we aim to be both principled and pragmatic. Principled in our commitment to fundamental values, sovereignty, territorial integrity, the prohibition of the use of force except when consistent with the UN Charter and respect for human rights. 

[translation] we're not going to be a bully. We won't fight unless we have to

And pragmatic in recognizing that progress is often incremental, that interests diverge, that not every partner will share all of our values.

So we’re engaging broadly, strategically, with open eyes. We actively take on the world as it is, not wait around for a world we wish to be.

[translation] Seriously, we're up for teaming up. Even with some weirdos. 

We are calibrating our relationships so their depth reflects our values, and we’re prioritizing broad engagement to maximize our influence, given the fluidity of the world at the moment, the risks that this poses and the stakes for what comes next.

And we are no longer just relying on the strength of our values, but also the value of our strength.

We are building that strength at home. Since my government took office, we have cut taxes on incomes, on capital gains and business investment. We have removed all federal barriers to interprovincial trade. We are fast tracking $1 trillion of investments in energy, AI, critical minerals, new trade corridors and beyond. We’re doubling our defence spending by the end of this decade, and we’re doing so in ways that build our domestic industries. And we are rapidly diversifying abroad. 

[translation] Canada's pretty awesome. As Katy Perry said to Justin: "you're gonna hear me roar."

We’ve agreed to a comprehensive strategic partnership with the EU, including joining SAFE, the European defence procurement arrangements. We have signed 12 other trade and security deals on four continents in six months.

In the past few days, we’ve concluded new strategic partnerships with China and Qatar. We’re negotiating free trade pacts with India, ASEAN, Thailand, Philippines and Mercosur.

[translation] See, I told you we're teaming up. Watch this space; more to come. 

We’re doing something else: to help solve global problems, we’re pursuing variable geometry. In other words, different coalitions for different issues based on common values and interests. So on Ukraine, we’re a core member of the Coalition of the Willing and one of the largest per capita contributors to its defence and security.

On Arctic sovereignty, we stand firmly with Greenland and Denmark and fully support their unique right to determine Greenland’s future.

[translation] Hey Donny, back off from Greenland. 

Our commitment to NATO’s Article 5 is unwavering, so we’re working with our NATO allies, including the Nordic-Baltic Eight, to further secure the alliance’s northern and western flanks, including through Canada’s unprecedented investments in over-the-horizon radar, in submarines, in aircraft, and boots on the ground — boots on the ice.

Canada strongly opposes tariffs over Greenland and calls for focused talks to achieve our shared objectives of security and prosperity in the Arctic.

On plurilateral trade, we’re championing efforts to build a bridge between the Trans-Pacific partnership and the European Union, which would create a new trading bloc of 1.5 billion people on critical minerals.

[translation] Oooh, let's make a Pacific Union thingy. Yes!

We’re forming buyer’s clubs anchored in the G7 so the world can diversify away from concentrated supply. And on AI, we’re cooperating with like-minded democracies to ensure that we won’t ultimately be forced to choose between hegemons and hyperscalers.

This is not naïve multilateralism, nor is it relying on their institutions. It’s building coalitions that work issue by issue with partners who share enough common ground to act together. In some cases, this will be the vast majority of nations. What it’s doing is creating a dense web of connections across trade, investment, culture on which we can draw for future challenges and opportunities.

[translation] We'll partner with the right people. In some cases, that's pretty much EVERYONE EXCEPT YOU Donald. 

Our view is the middle powers must act together because if we’re not at the table, we’re on the menu.

[translation] No, really, I think I said this before, but: we're up for teaming up.  

But I’d also say that great powers can afford, for now, to go it alone. They have the market size, the military capacity, and the leverage to dictate terms. Middle powers do not. But when we only negotiate bilaterally with a hegemon, we negotiate from weakness. We accept what’s offered. We compete with each other to be the most accommodating.

This is not sovereignty. It’s the performance of sovereignty while accepting subordination.

[translation] Oh, you thought you were your own country? Yeah right. We've all just been under Donald's thumb. No more!!! 

In a world of great power rivalry, the countries in-between have a choice: compete with each other for favour, or combine to create a third path with impact. We shouldn’t allow the rise of hard power to blind us to the fact that the power of legitimacy, integrity, and rules will remain strong if we choose to wield it together.

Which brings me back to Havel. What does it mean for middle powers to live the truth?

[translation] Remember the greengrocer? I'm winding things up now.

First, it means naming reality. Stop invoking rules-based international order as though it still functions as advertised. Call it what it is: a system of intensifying great power rivalry where the most powerful pursue their interests using economic integration as coercion.

[translation] Remember: Trump's a bully 

It means acting consistently, applying the same standards to allies and rivals. When middle powers criticize economic intimidation from one direction but stay silent when it comes from another, we are keeping the sign in the window.

It means building what we claim to believe in, rather than waiting for the old order to be restored. It means creating institutions and agreements that function as described, and it means reducing the leverage that enables coercion.

That’s building a strong domestic economy. It should be every government’s immediate priority.

And diversification internationally is not just economic prudence; it’s a material foundation for honest foreign policy, because countries earn the right to principled stands by reducing their vulnerability to retaliation.

So, Canada. Canada has what the world wants. We are an energy superpower. We hold vast reserves of critical minerals. We have the most educated population in the world. Our pension funds are amongst the world’s largest and most sophisticated investors. In other words, we have capital talent. We also have a government with immense fiscal capacity to act decisively. And we have the values to which many others aspire.

Canada is a pluralistic society that works. Our public square is loud, diverse and free. Canadians remain committed to sustainability. We are a stable and reliable partner in a world that is anything but, a partner that builds and values relationships for the long term.

And we have something else: we have a recognition of what’s happening and determination to act accordingly. We understand that this rupture calls for more than adaptation. It calls for honesty about the world as it is.

[translation] Canada has it all! Oh, Canada! Check out Nicola's article about this...  https://thetyee.ca/Opinion/2026/01/20/Dirty-Math-Trump-Thirst-Oil/ 

We are taking a sign out of the window.

We know the old order is not coming back. We shouldn’t mourn it. Nostalgia is not a strategy, but we believe that from the fracture we can build something bigger, better, stronger, more just. This is the task of the middle powers, the countries that have the most to lose from a world of fortresses and the most to gain from genuine cooperation.

[translation] The US Empire is dead. No worries. The Pacific Union thingy will be better. 

The powerful have their power. But we have something too: the capacity to stop pretending, to name realities, to build our strength at home, and to act together.

That is Canada’s path. We choose it openly and confidently, and it is a path wide open to any country willing to take it with us.

[translation] JOIN US! 

Thank you very much.

[translation]: mike drop. Thanks for the standing-o. Peace out.


Counting up what Trump's illegal move into Venezuela means for the climate, and for Canada.

U.S. President Donald Trump’s capture of Venezuelan President Nicolás Maduro and his declaration that the United States will now “run” Venezuela are deeply concerning on a number of levels: political, legal and moral. But we should not forget, either, about the environmental cost of Trump’s plan to ramp up production of Venezuelan oil. Nor should we ignore what Trump’s growing hunger for other countries’ natural resources might mean for Canada in the coming years.

My interview with Jimmy Wales, Wikipedia founder

I had the great fortune of chatting with Jimmy Wales before Christmas about the early days and evolution of Wikipedia, his recent book on trust, and how AI might help (or hinder) the spread of truth.

Check it out in Nature today https://www.nature.com/articles/d41586-026-00083-0 

PS, I remember when my Nature colleague Jim Giles first did an investigation of the veracity of Wikipedia, pitting it against Britannica with expert human reviewers (https://www.nature.com/articles/438900a). That was a big deal at the time, and earned Jim his own page in Wikipedia (yes, I'm jealous). That study is referenced in Wales' book, and is still one of the foundational proofs that the concept (of getting random people to pen and edit encyclopedia articles) is sound!

Canada’s first volcano monitoring station

In the spring of 2026, Canada is set -- finally -- to get its first dedicated and continuous volcano monitoring station. And it's going to be right in my back yard.

Mount Meager, one of Canada's two most hazardous volcanoes and the source of Canada's largest ever recorded landslide, is just 60km or so up the valley from where I live in Pemberton, BC. The active volcano last erupted 2,400 years ago, and is today spewing hot gas and  sloughing rock and gravel down its slopes. It could erupt tomorrow, or tens of thousands of years from now. For lack of monitoring, no one knows.
 
The station is set to be just the first in a set of instruments needed to establish an early warning system for residents like our family. Read my story in the Pique:

Everything you ever wanted to know about the measles surge

Canada just lost its 'measles elimination' status in the face of endemic and surging cases. Read my story for Nature.

https://www.nature.com/articles/d41586-025-03769-z 

mini FAQ

Q: There are a lot of news stories about people deciding not to get vaccinated. Is that behind the surge?

A: Yes and no. First, the rate of measles vaccination globally is going up, not down. (It took a hit during the pandemic and is still recovering back to pre-pandemic levels, but it is rising).

Most countries, including Canada and the US and the UK, don't hit the recommended level of 95% vaccination. But that's usually okay. You can beat back the disease in a country with a much lower level of vaccination than that. Overall, Canada and the US and the UK do have fairly high vaccination rates, around 90%.

BUT outbreaks do often happen in spots/communities where vaccination levels are low and so one case spreads. That's hard to fight back against.

Q: Is Canada doing really badly for measles?

A: Yes and no. Very badly indeed for Canada -- it's the worst surge in decades. But other countries have seen and do see far worse. The top country for measles this year is Yemen, with about 200,000 cases; Canada has seen just under 5,000. Globally, 2024 was worse for measles caseloads than 2025, and 2019 was far worse. In 2024 Europe was particularly hard hit, and in 2019 Africa had a lot of cases.

Q: Will the US follow?

A: Maybe. The Texas outbreak happened in January 2025, and if cases keep going to January 2026 then they too will loose their 'elimination status'. 

Q: what should we do about it?

A: get your kids vaccinated! While it's true that even a relatively high national level of vaccination isn't bomb-proof protection against outbreaks, vaccination will help your child and their friends and everyone in your community. Don't be part of the 'gaps' in coverage that let outbreaks happen.
