Next week, the White House is hosting a Summit on Countering Violent Extremism (known to most laypeople as “terrorism”). It was originally scheduled for last year but got delayed – and then put back on the calendar after the Paris attacks in January. What should we expect from a summit like this? “Alas, I’m expecting very little of a positive nature,” Col. (Ret.) Jack Jacobs tells us. “I view this principally as a media event. I hope I’m wrong.”
Just in case the summit does turn out to be primarily a media event, we thought we’d take our podcast – which technically, is a media event – and turn it into a terrorism summit. This week’s episode is called “Is There a Better Way to Fight Terrorism?” (You can subscribe to the podcast at iTunes or elsewhere, get the RSS feed, or listen via the media player above. You can also read the transcript, which includes credits for the music you’ll hear in the episode.) Read More »
Very interesting backgrounder on Stephen Salter, the British scientist who, in the course of trying to turn ocean waves into electric power, discovered a potential way to prevent, or at least limit, the impact of hurricanes:
Devastating tropical storms of the kind that battered the U.S. last week could be weakened and rendered less deadly using a simple and cheap technology based on a surprising component – old car tyres.
One of Britain’s leading marine engineers, Stephen Salter, emeritus professor of engineering design at Edinburgh university and a global pioneer of wave power research, has patented with Microsoft billionaires Bill Gates and Nathan Myhrvold the idea of using thousands of tyres lashed together to support giant plastic tubes which extend 100m deep into the ocean.
Wave action on the ocean surface would force warm surface water down into the deeper ocean. If non-return valves were used, he says, the result would be to mix the waters and cool the surface temperature of the ocean to under 26.5C, the critical temperature at which hurricanes form.

Until not so long ago, chicken feet were essentially waste material. Now they provide enough money to keep U.S. chicken producers in the black — by exporting 300,000 metric tons of chicken “paws” to China and Hong Kong each year. In the first part of this hour-long episode of Freakonomics Radio, host Stephen Dubner explores this and other examples of weird recycling. We hear the story of a Cleveland non-profit called MedWish, which ships unused or outdated hospital equipment to hospitals in poor countries around the world. We also hear Intellectual Ventures founder Nathan Myhrvold describe a new nuclear-power reactor that runs on radioactive waste. Read More »
Michael Specter has written a good and interesting New Yorker article about the history and current state of geoengineering, called “The Climate Fixers: Is There a Technological Solution to Global Warming?”
Let me rephrase:
Michael Specter has written a good and interesting New Yorker article about the history and current state of geoengineering, called “The Climate Fixers: Is There a Technological Solution to Global Warming?,” which is essentially a New Yorkerized version of Chapter 5 of SuperFreakonomics, all the way down to the Mount Pinatubo explosion and the reliance on scientists Ken Caldeira and Nathan Myhrvold.

Yes! That’s the argument in a new Historical Biology paper called “A Call to Search for Fossilized Gastric Pellets.” Here’s the abstract:

Numerous extant carnivorous, piscivorous and insectivorous species – including birds, pinnipeds, varanid lizards and crocodiles and mammals – routinely ingest food combined with a high proportion of indigestible material that can be neither absorbed through digestion nor eliminated as faecal matter. Their solution is to egest the indigestible portion through the mouth as a gastric pellet. The status of gastric pellets in extant species is reviewed. Arguments based on phylogeny, anatomy and biomechanics strongly suggest that many extinct species, including crocodilians and pterosaurs, may also have produced gastric pellets routinely.
Parts of the East Coast are still recovering from the destruction of Hurricane Irene. The storm wreaked havoc, causing more than 40 deaths and billions of dollars in damages. One thing that is striking about hurricanes is that, even after years of study, all we really know how to do is deal with the symptoms; we don’t actually have a way to treat the disease itself.
So what if there were a hurricane “vaccine”? Read More »
