Making metamaterials ‘digital’ could simplify invisibility cloaks
The digital world of 1s and 0s has inspired a simpler way to make complex metamaterials.
- Quantum Physics
Three photons entangled, not just two
Physicists have found a way to entangle a trio of photons, but it works only once in every quadrillion attempts.
- Particle Physics
Evidence for new Higgs-related particle fades away
A close look at data from the Large Hadron Collider finds no evidence that the Higgs boson decays into a new, unknown particle.
- Tech
Robot swarm takes many shapes
One Kilobot is not very smart. But 1,000 can follow simple instructions to assemble into multiple shapes without human intervention.
- Materials Science
Magnets get flipped by light
Controlling magnetism with lasers could lead to faster computer hard drives.
- Environment
Ups and downs in the quest for clean air
Satellite views reveal good news on U.S. air pollution trends.
- Cosmology
Cosmologist’s ‘Cosmic Cocktail’ is a refreshing read
Katherine Freese shares her insights as a scientist studying dark matter and other mysterious components of the universe.
- Computing
Brain-inspired computer chip mimics 1 million neurons
By processing data in parallel, computer chips modeled after the human brain could perform certain tasks, such as pattern recognition, faster and more energy-efficiently than traditional computers.
- Quantum Physics
Quantum Cheshire Cat experiment splits particles from their properties
When facing a fork in the road, neutrons appear to go in one direction and their spins in the other.
- Materials Science
Weird materials could make faster computers
Topological insulators could speed up how computers switch between 1s and 0s.
- Astronomy
Voyager may not have entered interstellar space, after all
Two scientists argue that Voyager 1 space probe is still in solar bubble, despite NASA’s announcements to the contrary.
- Cosmology
Lab version of early universe fails to solve lithium problem
An experiment that imitated conditions from just after the Big Bang failed to explain why observed amounts of lithium don’t match those expected from theory.
