We summarize the week's scientific breakthroughs every Thursday.
- Quantum Physics
Milestone algorithm runs on quantum computer
An algorithm proposed two decades ago that demonstrated the benefit of using quantum mechanics to solve certain problems has finally been run on a quantum computer.
- Materials Science
Batteries become safe to swallow with spongy covering
Quantum-inspired coating switches from a conductor to an insulator to prevent injury from swallowed batteries.
- Materials Science
‘Impermeable’ graphene yields to protons
Graphene sheets, impermeable to all atoms and molecules, can be penetrated by protons, new study shows.
- Cosmology
Gamma rays offer mixed messages on identity of dark matter
Conflicting results from Fermi telescope puzzle astronomers about dark matter’s true identity.
- Physics
Magnetic detector identifies single protons
An MRI-like machine can scan an individual proton, raising prospects that a similar technique could eventually image biological molecules one by one.
- Physics
Laser tractor beam tugs on beads
A new experiment is the first to construct a tractor beam that can pull objects over long distances with light.
- Physics
Perfect fluid of electrons may flow inside superconductor
Understanding superconductors’ viscosity could help inspire scientists to find ways to improve the electric power grid.
- Physics
Complete double rainbow encircles Australian town
A photographer in a helicopter captured a double circular rainbow while flying around a storm near Perth, Australia.
- Particle Physics
New particle could help physicists understand subatomic glue
A newfound particle will allow scientists to probe the universe’s strongest force.
- Physics
Falling raindrops break terminal velocity
Unknown mechanism causes tiny raindrops to fall faster than terminal velocity.
- Quantum Physics
Hawking radiation spotted within sonic black hole
Lab-created sonic black hole emits energy as famed physicist Stephen Hawking predicted, though the experiment may not be definitive.
- Materials Science
Blue LEDs win Nobel Prize in physics
Light-emitting diodes have led to more energy-efficient bulbs that are elbowing out incandescents.
