In joint experimental-theoretical research published in Nature, physicists at the Heidelberg Max Planck Institute for Nuclear Physics (MPIK), together with collaborators from RIKEN, Japan, investigated the magnetic properties of the isotope helium-3. For the first time, the electronic and nuclear g-factors of the 3He+ ion were measured straightly with a relative accuracy of 10– 10. […]

The reinforcement learning algorithm, which controls the scorching plasma within a tokamak nuclear fusion reactor, was developed by an AI company backed by Google. The interior of a tokamak– the doughnut-shaped vessel created to include a nuclear fusion reaction– presents a unique type of chaos. Hydrogen atoms are shattered together at unfathomably high temperatures, developing

Researchers have developed self-assembled, protein-based circuits that can do simple logic functions in proof-of-concept research. The work demonstrates that it is possible to develop stable digital circuits that benefit from an electron’s properties at quantum scales. Molecular circuits One of the stumbling blocks in developing molecular circuits is that the circuits become unreliable as the

After a three-year recess, protons have begun circulating once more in the particle accelerator After a respite of over three years, the Large Hadron Collider is back. The Large Hadron Collider has returned after a break of more than three years. In 2018, scientists shut down the particle accelerator for upgrades (SN: 12/3/18). On April

There has been significant excitement about recent results from the Joint European Torus (JET) facility in the UK, suggesting that the dream of nuclear fusion power is inching closer to reality. We know that fusion works– it is the process that powers the Sun, offering heat and light to the Earth. For years, it has

The nature of dark matter stills astonishes astronomers. As the search for dark matter particles keeps on turning up nothing, it is tempting to throw away the dark matter model altogether, but indirect evidence for the stuff remains to be strong. So what is it? One team has an idea, and they have released the

In the initial millionths of a second after the Big Bang, our universe was an agitated pull of subatomic particles, trillion-degree plasma of quarks and gluons– elementary particles that were briefly interacting with each other on countless combinations before cooling down and settling into more stable configurations to make the neutrons and also protons of

Can machine learning be used to reveal the secrets of the quark-gluon plasma? Yes, it can. However, only with advanced new methods. It can hardly be more complicated. Little particles whir around wildly with extremely high energy, many interactions happen in the matted mess of quantum particles. This leads to a state of matter called

Fragment Zoo Physical scientists thought there were only three basic elements for most of the first half of the twentieth century: the known proton, neutron, and electron. Nonetheless, by the mid-1960s, that image had shifted. Improvements to particle accelerators and detector technology set the stage for the discovery of a seemingly infinite number of new

Community Fusion System (CFS) and MIT’s Plasma Science and Fusion Center claimed that a high-temperature superconducting magnet was successfully tested. The 20-tesla field intensity, according to MIT researchers and CFS, is the most intense electromagnetic field ever created on Earth, paving the way for the construction of the first fusion power generator. Magnet design is
