Physics
We summarize the week's science breakthroughs every Thursday.
- Physics
Neutron star collisions probably make more gold than other cosmic smashups
Smashups of two neutron stars produce more heavy elements than when a black hole swallows a neutron star, calculations suggest.
- Space
A rush to watch a supernova exposed its last gasp before exploding
By studying the final years of stars, scientists hope to find clues to help them recognize when other stars are about to blow.
- Materials Science
Lithium-ion batteries made with recycled materials can outlast newer counterparts
Batteries with recycled cathodes outperformed batteries with new cathodes, lasting for thousands more charging cycles before their capacity waned.
- Particle Physics
Doubt cast on theorized ‘sterile’ particles leaves a neutrino mystery unsolved
MicroBooNE weakens the case for sterile neutrinos, but the mystery that shrouded earlier neutrino experiments remains.
- Earth
Here’s how ice needles sculpt patterns into cold, rocky landscapes
Striking stone patterns decorate remote, frigid landscapes. The recipe for these naturally forming stripes and swirls: Freeze, thaw, repeat.
- Physics
Here’s the physics of why ducklings swim in a row behind their mother
By paddling in just the right spots, ducklings save energy by surfing their mom’s waves, and pass along the benefit to siblings down the line.
- Physics
An atomic clock measured how general relativity warps time across a millimeter
A record-breaking result reveals the precision achievable by atomic clocks, letting researchers detect slightly faster ticking over a tiny height change.
- Physics
Work on complex systems, including Earth’s climate, wins the physics Nobel Prize
Syukuro Manabe and Klaus Hasselmann pioneered work on computer simulations of Earth’s climate. Giorgio Parisi found hidden patterns in disordered complex materials.
- Quantum Physics
Scientists are one step closer to error-correcting quantum computers
In a quantum computer made with trapped ions, multiple quantum bits were combined into one to detect mistakes.
- Materials Science
These colorful butterflies were created using transparent ink
See-through printer ink can create a whole spectrum of colors when printed in precise, microscale patterns.
- Physics
Whirling maple seeds inspired these tiny flying sensors
Scientists envision that small objects modeled after maple tree whirligigs could be used to monitor the environment.
- Quantum Physics
One of nature’s key constants is much larger in a quantum material
The fine-structure constant is 10 times its normal value in the material, giving a peek into what physics in an alternate universe could look like.
