Observation of skyrmions in a ferromagnet with centrosymmetry

Researchers from the National Institute of Materials Science (NIMS) have used Lorentz electron microscopy to show that magnetic skyrmions are spontaneously formed as nanomagnetic clusters in a ferromagnetic manganese oxide ...

New research shows that graphene is able to seal holes in itself automatically

(Phys.org) -- Graphene, the one carbon atom thick sheet material has been in the news so much over the past couple of years it would seem that a saturation point has been reached. But then along comes another new discovery ...

Plant species living in urban backyards are closer related to each other and live shorter than species in the countrysid

Cities in both, the US and Europe harbour more plant species than rural areas. However, plant species of urban areas are closer related to each other and often share similar functions. Consequently, urban ecosystems should ...

Topological matter in optical lattices

Atoms trapped by laser light have become excellent platforms for simulating solid state systems. These systems are also a playground for exploring quantum matter and even uncovering new phenomena not yet seen in nature.

New malaria protein structure upends theory of how cells grow and move

Researchers from the Walter and Eliza Hall Institute have overturned conventional wisdom on how cell movement across all species is controlled, solving the structure of a protein that cuts power to the cell 'motor'. The protein ...

Defective plastics repair themselves

Indestructible things are a figment of the imagination of advertising. Even plastic components that have to stand up to major mechanical loads can break. The reason for this are microcracks that may be found in any component ...

Physicists find evidence of new state of matter in a simple oxide

Symmetry is a fundamental concept in physics. Our ‘standard model’ of particle physics, for example, predicts that matter and anti-matter should have been created in equal amounts at the big bang, yet our existing universe ...

Scientists discover, visualize exotic electrons on surfaces of unique insulators

(PhysOrg.com) -- In two separate studies, Princeton-led teams of scientists have found a new type of “light-like” electron and visualized for the first time another type that doesn’t bounce back when material imperfections ...
