Magnetic Fields on the Moon are the Remnant of an Ancient Core Dynamo

Presently, the moon does not have an internal magnetic field as it can be observed on Earth. However, there are localized regions on its surface up to several hundred kilometers in size where a very strong magnetic field prevails.

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.
