Ancient dwarf galaxy was heavy-element factory
A rare event in an ancient galaxy left traces of heavy elements in its stars.
- Cosmology
How to make gravitational waves ‘sing’
A rapidly spinning black hole would make a unique pattern of gravitational waves when it sucks in a smaller companion.
- Cosmology
New sky map charts previously unknown gamma-ray sources
A new map of the sky from the High-Altitude Water Cherenkov Observatory charts the cosmic origins of high-energy photons.
- Quantum Physics
Information is physical, even in quantum systems, study suggests
A thermodynamic principle says that deleting information generates heat, and now, scientists say that goes for quantum systems, too.
- Physics
Itty bitty engine puts a single atom to work
Scientists have created a miniature heat engine out of a single atom.
- Quantum Physics
Gamers outperform computer at quantum task
Quantum mechanics may be weird, but a new video game shows that human intuition can still best computers at quantum tasks.
- Physics
Turning water to steam, no boiling required
A new material can convert water into steam with sunlight alone, and could be useful for making fresh water from salty.
- Astronomy
Possible source of high-energy neutrino reported
Scientists may have found the cosmic birthplace of an ultra-high energy neutrino: a blazar 9 billion light years away.
- Physics
Faint gravitational waves could soon be on LIGO’s radar
In a few years, LIGO could detect hints of faint gravitational waves from black holes too far away to be seen directly.
