Billionaires with big ideas are privatizing American science
Last April, President Barack Obama assembled some of the nation’s most august scientific dignitaries in the East Room of the White House.

Research reactors seen as security risk
In Cambridge, Mass., at the Massachusetts Institute of Technology, a nuclear reactor emits an eerie blue glow 24 hours a day, 7 days a week. Its fuel is 93 percent uranium 235 — the high-purity uranium it takes to energize an atom bomb and exactly what the West fears that Tehran wants to produce.

New commercial satellite photos show that a Syrian site Israel bombed in September no longer bears any obvious traces of what analysts said appeared to have been a partly built nuclear reactor.
Once Just an Inconvenience, Orbiting Junk Now a Threat
For decades, space experts have worried that a speeding bit of orbital debris might one day smash a large spacecraft into hundreds of pieces and start a chain reaction, a slow cascade of collisions that would expand for centuries, spreading chaos through the heavens.
Iran Nuclear Technology Report Reveals U.S., U.N. Policy Discord
