Are rare earth shortages the real bottleneck in semiconductor supply chains? Our new paper in @IEEEorg Transactions on Engineering Management introduces a multi-level hybrid simulation framework to stress-test critical mineral dependencies. 🧵👇 doi.org/10.1109/TEM....

Pleased to have written this new piece for @ConversationUK. 📝 We are witnessing a critical, overlooked consequence of the ongoing Iran war: the rapid depletion of global tungsten supplies. Here’s why it matters for the world's militaries. 🧵👇 theconversation.com/the-iran-war...

The Iran war has depleted supplies of tungsten, a critical mineral for the world’s militaries
The element is used in everything from missiles to armoured vehicles.

The world’s supply of helium is being threatened by the Iran war
Helium, a critical material, could be in short-supply due to Qatar’s suspension of gas production.

Nice to be quoted in this article by Fran Roberts-Thornton in Which magazine talks about our insatiable appetite for Critical Materials in tech, and how we can reduce our consumption of them by extending the life of our devices and making them last for longer.

🚗⚡ How is the global shift to electric vehicles really unfolding? Our new discussion paper from the Centre for Economic Performance at @LSE dives into the economics of the EV transition: demand, supply chains, and innovation. A quick thread on our key findings 🧵👇 cep.lse.ac.uk/_new/publica...

The economics of the electric vehicle transition: demand, supply chains, and innovation
Electric vehicles (EVs) are central to decarbonising road transport, a sector responsible for 23% of global energy-related emissions, and their adoption carries both economic and societal implications. This paper provides an economic review of EV transitions, synthesizing theory, stylized facts, and frontier empirical findings. We document three key observations: EV adoption has historically occurred in waves that stalled and revived; contemporary adoption is highly heterogeneous across countries; and the transition reshapes automotive sector activities and supply chains, increasing reliance on geographically concentrated critical minerals and generating Environmental, Social and Governance (ESG) and political economy challenges. We then analyze the economic drivers of adoption, including total cost of ownership, network externalities, and complementary technologies such as charging infrastructure, grid integration, and digital innovations. Supply-side constraints, resource scarcity, and innovation dynamics are examined, highlighting how the EV platform interacts with broader technological and industrial systems. The analysis emphasizes the systemic, path-dependent, and platform nature of EV transitions and outlines policy-relevant insights for managing adoption, supply chains, and innovation. Finally, we identify avenues for future research, including the economics of end-of-life and used EVs, resilient supply chains, and the role of complementary technologies in accelerating low-carbon transitions.

Free and fair elections are the cornerstone of our democracy. But right now, they’re under attack. Several Republican-controlled states have redrawn their congressional maps to give themselves an unfair advantage in the midterm elections.

For the first time in history, the state of Virginia has a female Governor and right after being sworn in today Governor Abigail Spanberger’s first official act was to end cooperation between ICE-Gestapo and Virginia State Police. More of this. 💙👊👏

The first thing Virginia Spanberger did after being sworn in as Governor of Virginia was repeal Youngkin’s executive order requiring state and local law enforcement to cooperate with ICE. This is the kind of leadership Democratic governors nationwide should be emulating.

This is now the second-longest government shutdown of any kind ever in the history of our country. The two longest shutdowns in US history both while Trump was in office. He is the common denominator. That needs to start being the headline.

They use govt accounts, employees & resources to make partisan political messages. They make partisan political speeches attacking the opposition party to troops routinely. They get pardoned when they commit crimes. They ignore the laws. There is zero congressional oversight.
