Some recent articles

I occasionally write about this blog’s themes for The Economist, here are a few recent pieces:

On nuclear fusion

Recent developments have made some people optimistic that “net energy gain” reactions—the holy grail where a nuclear fusion reaction produces more energy than it consumes—could soon be achieved.

On biological weapons

If a pathogen was engineered to be particularly virulent and lethal, it could kill millions of people across the globe. Researchers at Oxford University’s Future of Humanity Institute think such a weapon could even lead to human extinction.

On surviving nuclear war

Potassium iodide can help, but only up to a point. It stops the thyroid, a gland in the neck, from absorbing radioactive iodine. The pills have been distributed in the aftermath of nuclear power-plant meltdowns, and there is evidence to suggest they work.

My colleagues are constantly writing excellent pieces, too; you should subscribe to read them all.
