Harnessing hot helium ash to drive rotation in fusion reactors

In controlled nuclear fusion, heavy isotopes of hydrogen fuse into helium, releasing a huge amount of energy in the process. A large portion of the energy released by a laboratory fusion reaction goes into hot helium ash ...

Discovery of fastest ever magnetic wave propagation

Like light waves, magnetic waves move through materials at a fixed maximum velocity. However, at the smallest possible length scale (nanometres) and the shortest possible time scale (femtoseconds), magnetism behaves differently. ...

Energy harvesting technology based on ferromagnetic resonance

Researchers from the Graduate School of Engineering, Osaka City University have succeeded in storing electricity with the voltage generated from the conversion phenomenon of ferromagnetic resonance (FMR) using an ultra-thin ...

Coastal wetlands are nature's flood defences

Coastal wetlands—such as salt marshes—provide even more flood protection than previously thought, reducing the risk to lives and homes in estuaries, a new study has revealed.

New detector finds gamma rays from surprising cosmic sources

Astrophysicist Cao Zhen opens a steel hatch on a windswept Tibetan Plateau and climbs down a ladder into inky darkness. His flashlight picks out a boat floating on a pool of purified water above thousands of glittering orbs ...
