- Physics
Supercooled water has been caught morphing between two forms
A new experiment used ultrafast techniques to reveal high-density water transforming into low-density water at subfreezing temperatures.
- Physics
Giant lasers help re-create supernovas’ explosive, mysterious physics
For the first time, scientists have re-created a type of shock wave that occurs in supernovas.
- Physics
LIGO and Virgo’s gravitational wave tally more than quadrupled in six months
Scientists report 39 sets of spacetime ripples from just half a year of data.
- Quantum Physics
Galileo’s famous gravity experiment holds up, even with individual atoms
When dropped, two types of atoms accelerate at the same rate despite their differences, much like objects in Galileo’s leaning Tower of Pisa experiment.
- Math
A documentary and a Bollywood film highlight two disparate paths in mathematics
An unlikely pair of films recount tales of two very different mathematical women, Maryam Mirzakhani and Shakuntala Devi.
- Physics
The first room-temperature superconductor has finally been found
A compound of carbon, hydrogen and sulfur conducts electricity without resistance up to 15° C, but there’s a catch: It works only under high pressure.
- Physics
Fundamental constants place a new speed limit on sound
Physicists propose a new maximum rate that sound waves can travel under conditions normally found on Earth — 36 kilometers per second.
- Physics
Black hole revelations win the 2020 Nobel Prize in physics
The Nobel Prize in physics was awarded to a trio of scientists for their work on the most mysterious objects in the universe: black holes.
- Physics
A stop-motion experiment reveals supercooled water’s dual nature
Scientists found signs that water cooled well below freezing consists of two different arrangements of molecules.
- Physics
Record-breaking gravitational waves reveal that midsize black holes do exist
The biggest merger of two black holes so far raises questions about how the pair of objects came to be.
- Quantum Physics
A measurement of positronium’s energy levels confounds scientists
A gap in the energy levels of positronium seems to be substantially larger than predicted, and physicists don’t know why.
- Physics
Four types of flames join forces to make this eerie ‘blue whirl’
Pinning down the structure of the “amazingly complex” blaze could help scientists control it.
