For the first time, scientists have ‘photographed’ a rare plasma instability, where high-energy electron beams form into spaghetti-like filaments.

A new study, published in Physical Review Letters, outlines how a high-intensity infrared laser was used to generate filamentation instability—a phenomenon that affects applications in plasma-based particle accelerators and fusion energy methods.

Plasma is a super-hot mixture of charged particles, such as ions and electrons, which can conduct electricity and are influenced by magnetic fields. Instabilities in plasmas can occur because the flow of particles in one direction or within a specific region can be different from the rest, causing some particles to group up into thin spaghetti-like filaments.

Neutrinos generated through solar fusion reactions travel effortlessly through the sun’s dense core. Each specific fusion process creates neutrinos with distinctive signatures, potentially providing a method to examine the sun’s internal structure. Multiple neutrino detection observatories on Earth are now capturing these solar particles, which can be analyzed alongside reactor-produced neutrinos with the data eventually enabling researchers to construct a detailed map of the interior of the sun.

The sun is a massive sphere of hot plasma at the center of our solar system and provides the light and heat to make life on Earth possible. Composed mostly of hydrogen and helium, it generates energy through nuclear fusion, converting hydrogen into helium in its core. This process releases an enormous amount of energy which we perceive as heat and light.

The sun’s surface, or photosphere, is around 5,500°C, while its core reaches over 15 million°C. It influences everything from our climate to space weather, sending out solar wind and occasional bursts of radiation known as solar flares. As an average middle-aged star, the sun is about 4.6 billion years old and will (hopefully) continue burning for another 5 billion years before evolving into a red giant and eventually becoming a white dwarf.

The role of solar heat in earthquake activity https://pubs.aip.org/aip/cha/article-abstract/35/3/033107/33…m=fulltext

Seismology has revealed much of the basics about earthquakes: Tectonic plates move, causing strain energy to build up, and that energy eventually releases in the form of an earthquake. As for forecasting them, however, there’s still much to learn in order to evacuate cities before catastrophes like the 2011 magnitude 9.0 Tōhoku earthquake that, in addition to causing the tsunami that led to the Fukushima nuclear disaster, resulted in more than 18,000 deaths.

In recent years, research has focused on a possible correlation between the sun or moon and seismic activity on Earth, with some studies pointing to tidal forces or electromagnetic effects interacting with the planet’s crust, core, and mantle.

In Chaos researchers from the University of Tsukuba and the National Institute of Advanced Industrial Science and Technology in Japan explored the likelihood that Earth’s climate, as affected by solar heat, plays a role.

A team of scientists has just landed a massive grant to build materials strong enough to withstand the blistering heat and radiation inside a fusion reactor, where temperatures soar beyond 180 million degrees Fahrenheit (100 million degrees Celsius).

The U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) allocated USD 2.3 million to the University of Kentucky to lead the development of next-generation materials that could make commercial fusion power a reality.

Moltex’s WATSS technology transforms nuclear waste into a valuable energy resource, offering a cost-effective solution for the industry.

France just achieved a nuclear fusion breakthrough, making limitless energy virtually inevitable.

In a major achievement, France’s WEST Tokamak reactor has maintained a plasma reaction for over 22 minutes, setting a new world record in the quest for sustainable fusion energy.

énergie atomique et aux énergies alternatives (CEA), the experiment surpassed China’s previous record of 1,066 seconds, reaching 1,337 seconds of sustained plasma. + This milestone is a major step toward commercial fusion power, which promises unlimited, clean energy by harnessing the same process that powers the Sun. The challenge lies in achieving a self-sustaining reaction while maintaining extreme temperatures of up to 150 million°C (270 million°F) without damaging reactor components.

While WEST itself won’t become a commercial reactor, the data gathered will be instrumental in developing ITER, the world’s largest fusion project, currently under construction in southern France.

CEA scientists plan to extend reaction times further, increasing power levels and plasma stability. If successful, these advancements could bring humanity closer to realizing the long-held dream of clean, virtually limitless energy, potentially transforming global power generation in the future.
