We summarize the week's scientific breakthroughs every Thursday.
- Chemistry
New method leaves older ways of 3-D printing in its goopy wake
Finding the sweet spot in a pool of resin, chemists can create detailed 3-D objects faster than 3-D printers.
- Materials Science
Copper-wire ‘metamirror’ reflects selectively
A metamaterial mirror reflects only a single wavelength of light, potentially leading to more compact and affordable radio antennas.
- Quantum Physics
Finding quantum entanglement in a crowd
Physicists have measured entanglement between pairs of photons within a macroscopic beam of light, a first step toward understanding how particles’ quantum connections lead to large-scale effects.
- Physics
High-temperature superconductivity record awaits confirmation
A hydrogen-sulfur compound under pressure may transport electrical current with no resistance at a record high temperature.
- Particle Physics
Sam Ting tries to expose dark matter’s mysteries
Particle physicist Sam Ting is applying a meticulous approach to analyzing positrons in space, testing whether they can reveal clues about dark matter.
- Quantum Physics
Light trick can retrieve missed messages
Even if photons pass you by, you can still snatch a signal from their electromagnetic wake, physicists propose.

Why lattes are less prone to spills than regular coffee
Foam dampens liquids’ sloshing, keeping keeps lattes and beer from spilling so easily, researchers find.
- Quantum Physics
Trying to get the down-low on gravity
A twist on a classic quantum mechanics experiment could lead to the discovery of elusive gravitons.
- Quantum Physics
Physicists double their teleportation power
In a teleportation first, physicists transfer two quantum properties from one photon to another.
