A quantum step to a heat switch with no moving parts

Researchers have discovered a new electronic property at the frontier between the thermal and quantum sciences in a specially engineered metal alloy—and in the process identified a promising material for future devices ...

DNA robots designed in minutes instead of days

Someday, scientists believe, tiny DNA-based robots and other nanodevices will deliver medicine inside our bodies, detect the presence of deadly pathogens, and help manufacture increasingly smaller electronics.

Rogue planets could outnumber the stars

An upcoming NASA mission could find that there are more rogue planets—planets that float in space without orbiting a sun—than there are stars in the Milky Way, a new study theorizes.

Scientists learn how vampire bat strangers make friends

We humans can explain how our relationships with college roommates and co-workers have formed over the years, but scientists haven't had a good grip on how friendly connections among strangers are made between animals—until ...

Current model for storing nuclear waste is incomplete

The materials the United States and other countries plan to use to store high-level nuclear waste will likely degrade faster than anyone previously knew because of the way those materials interact, new research shows.
