FROM Claudio Campagnari
Setbacks at Massive Particle Accelerator The Large Hadron Collider is a 17-mile underground racetrack where atomic particles will be accelerated to energies of seven trillion electron volts and be smashed together. When it was unveiled in Switzerland last September, some critics worried it might generate so much energy that a black hole would swallow the planet. Just weeks later, it suffered a debilitating accident, and now other problems have delayed the $9 billion LHC being turned on. Claudio Campagnari is a professor of physics at the University of California, Santa Barbara.
Will the march for science politicize objective research? Protesters are gathering all over the country for tomorrow's Earth Day March for Science. Since President Trump has proposed massive cuts in basic scientific research, will the movement be perceived as partisan politics — whether scientists themselves like it or not?

The Trump Administration says it has lost its "strategic patience." We hear what that might -- or might not -- mean for North Korea, China and the prospects for diplomacy.
