Cosmology Adrian Cho and Yudhijit Bhattacharjee
Signs of gravitational waves shaking the newborn universe bolster the mind-boggling theory of cosmic inflation and electrify scientists the world over.
U.S. Science Policy Jeffrey Mervis
Congressional Republicans and the National Science Foundation appear to be creeping toward common ground in their yearlong fight over how the agency manages its $7 billion research portfolio.
Jeffrey Mervis
The Democratic alternative to the Republican bill would encourage the National Science Foundation to support more of the same high-quality research it now funds.
Stem Cells Dennis Normile and Gretchen Vogel
As scientists around the world attempt to reproduce a new way to make stem cells—so far without success—Science has learned that several co-authors on the feted papers have not yet made the cells either.
Restoration Ecology Erik Stokstad
Hoping for a boost to native vegetation, scientists will study the effects of an experimental flood of the Colorado River delta on trees, soil salinity, and ground water.
