Scientists completed several successful attempts to fire 28 kilojoules of laser energy at small capsules filled with deuterium and tritium fuel, causing the capsules to implode and produce a plasma hot enough to initiate fusion reactions between the fuel nuclei. These results demonstrate an effective 'spark plug' for direct-drive methods of inertial confinement fusion.

Researchers recently succeeded in producing a highly durable time crystal that lived millions of times longer than could be shown in previous experiments. By doing so, they have corroborated an extremely interesting phenomenon that Nobel Prize laureate Frank Wilczek postulated around ten years ago and which had already found its way into science fiction movies.

Emerging research suggests it may be easier to use fusion as a power source if liquid lithium is applied to the internal walls of the device housing the plasma. Past experiments studied solid lithium coatings and found they could enhance a plasma. The researchers were pleased they could yield similar results with liquid lithium, as it's better suited for use in a large-scale tokamak.

New research conducted by nuclear physicists is using a method that connects theories of gravitation to interactions among the smallest particles of matter. The result is insight into the strong force, a powerful mediator of particle interactions in the subatomic realm. The research has revealed, for the first time, a snapshot of the distribution of the shear strength of the strong force inside the proton -- or how strong an effort must be to overcome the strong force to move an object it holds in its grasp. At its peak, the nuclear physicists found that a force of over four metric tons would be required to overcome the binding power of the strong force.

Antineutrinos generated in nuclear fission can be measured to remotely monitor the operation of nuclear reactors and verify that they are not being used to produce nuclear weapons, report scientists. Thanks to a newly developed method, it is now possible to estimate a reactor's operation status, fuel burnup, and fuel composition based entirely on its antineutrino emissions. This technique could contribute massively to nuclear non-proliferation efforts and, in turn, safer nuclear energy.

New findings debunk previous wisdom that solid-state qubits need to be super dilute in an ultra-clean material to achieve long lifetimes. Instead, cram lots of rare-earth ions into a crystal and some will form pairs that act as highly coherent qubits, a new paper shows.

During X-ray diffraction experiments, bright lasers shine on a sample, producing diffracted images that contain important information about the material's structure and properties. But conventional methods of analyzing these images can be contentious, time-consuming, and often ineffective, so scientists are developing deep learning models to better leverage the data.

A recent advance could enable more efficient compact fusion reactors that are easier to repair and maintain.

Oceans cover most of Earth's surface and support a staggering number of lifeforms, but they're also home to a dilute population of uranium ions. And -- if we can get these particular ions out of the water -- they could be a sustainable fuel source to generate nuclear power. Researchers have now developed a material to use with electrochemical extraction that attracts hard-to-get uranium ions from seawater more efficiently than existing methods.

How heavy can an element be? An international team of researchers has found that ancient stars were capable of producing elements with atomic masses greater than 260, heavier than any element on the periodic table found naturally on Earth. The finding deepens our understanding of element formation in stars.

Planetary rovers, which help humanity explore other planets, can deviate from their targeted paths or get stuck due to slipping on loose soil. To combat this problem, researchers have developed a novel system for rovers to detect their slip condition from the change in the shape of their chassis. This novel technology, inspired by human muscles, can lead to advanced sensing technologies that make travel safer for unmanned vehicles.

Physicists have started the countdown on developing a new generation of timepieces capable of shattering records by providing accuracy of up to one second in 300 billion years, or about 22 times the age of the universe.

Monitoring whether states are complying with disarmament treaties is not an easy task. An international team has been exploring remote monitoring with the help of two antennas and a couple of mirrors.

The results of the Chi-Nu physics experiment at Los Alamos National Laboratory have contributed essential, never-before-observed data for enhancing nuclear security applications, understanding criticality safety and designing fast-neutron energy reactors.

An international research team has taken a decisive step toward a new generation of atomic clocks. The researchers have created a much more precise pulse generator based on the element scandium, which enables an accuracy of one second in 300 billion years -- that is about a thousand times more precise than the current standard atomic clock based on caesium.

The neutron-rich oxygen isotopes oxygen-27 and oxygen-28 exist as very short-lived resonances, report scientists based on the first observation of their decay into oxygen-24 and three and four neutrons, respectively. Notably, the oxygen-28 nucleus is found not to be 'doubly magic' as expected in the standard shell-model picture. This study provides valuable insights into the nuclear structure.
