The Magnetic History of Ice
The history of our planet has been written, among other things, in the periodic reversal of its magnetic poles. Scientists at the Weizmann Institute of Science propose a new means of reading this historic record: in ice.
New type of coupled electronic-structural waves discovered in magnetite
An international team of scientists uncovered exotic quantum properties hidden in magnetite, the oldest magnetic material known to mankind.
Novel insight reveals topological tangle in unexpected corner of the universe
Scientists find a unique knotted structure -- one that repeats itself throughout nature -- in a ferroelectric nanoparticle, a material with promising applications in microelectronics and computing.
‘Hot and messy’ entanglement of 15 trillion atoms
Quantum entanglement is a process by which microscopic objects like electrons or atoms lose their individuality to become better coordinated with each other.
To make an atom-sized machine, you need a quantum mechanic
Here's a new chapter in the story of the miniaturisation of machines: researchers in a laboratory in Singapore have shown that a single atom can function as either an engine or a fridge. Such a device could be engineered into future computers and fuel cells to control energy flows.
Gravitational waves could prove the existence of the quark-gluon plasma
Neutron stars are among the densest objects in the universe. If our Sun, with its radius of 700,000 kilometres were a neutron star, its mass would be condensed into an almost perfect sphere with a radius of around 12 kilometres.
New findings suggest laws of nature not as constant as previously thought
Those looking forward to a day when science's Grand Unifying Theory of Everything could be worn on a t-shirt may have to wait a little longer as astrophysicists continue to find hints that one of the cosmological constants is not so constant after all.
New high-energy-density physics research provides insights about the universe
Atoms and molecules behave very differently at extreme temperatures and pressures. Although such extreme matter doesn't exist naturally on the earth, it exists in abundance in the universe, especially in the deep interiors of planets and stars.
New discovery helps close the gap towards optically-controlled quantum computation
Scientists at Ames Laboratory, Brookhaven National Laboratory, and the University of Alabama Birmingham have discovered a light-induced switching mechanism in a Dirac semimetal.
In search of the Z boson
At the Japanese High-energy Accelerator Research Organization, KEK, in Tsukuba, about 50 kilometers north of Tokyo, the Belle II experiment has been in operation for about one year now.
Where did the antimatter go? Neutrinos shed promising new light
We live in a world of matter - because matter overtook antimatter, though they were both created in equal amounts by the Big Bang when our universe began.
New protocol identifies fascinating quantum states
Nowadays, modern quantum simulators offer a wide range of possibilities to prepare and investigate complex quantum states.
They are realized with ultracold atoms in optical...
Looking for dark matter
Dark matter, which cannot be physically observed with ordinary instruments, is thought to account for well over half the matter in the Universe, but...
Origins of Earth’s magnetic field remain a mystery
Microscopic minerals excavated from an ancient outcrop of Jack Hills, in Western Australia, have been the subject of intense geological study, as they seem to bear traces of the Earth's magnetic field reaching as far back as 4.2 billion years ago.
A step ahead in the race toward ultrafast imaging of single particles
Using a combination of experimental and computational data, researchers discover paths to optimize pulses from highly intense X-ray beams.
