By taking into account the demographics and preferences of US racial groups, clarified through a nationally representative survey of 3,000 US residents, researchers have created a 'desirable' electricity generation mix for 2050 that includes 50% more energy from renewables than current projections. Combining such bottom-up input with top-down energy system goals set by policymakers could help meet both the needs and preferences of the population along with emission and climate goals.

Using data from the eruption of the underwater volcano near Tonga in 2022, researchers used disturbances in Earth's upper atmosphere to track the airwaves that cause tsunami. Their findings may lead to speedier predictions of these giant waves.

After almost two decades of synchrotron experiments, scientists have captured a clear picture of a cell's nuclear pores, which are the doors and windows through which critical material in your body flows in and out of the cell's nucleus. These findings could lead to new treatments of certain cancers, autoimmune diseases and heart conditions.

Researchers used a fiber optic cable on the ice cap of an Icelandic subglacial volcano to detect low-frequency volcanic tremor, suggesting this technology could be useful in monitoring other ice-covered volcano systems.

As it captivated people around the world, the January eruption of the Hunga Tonga-Hunga Ha'apai volcano gave scientists a once-in-a-lifetime chance to study how the atmosphere works, unlocking keys to better predict the weather and changing climate.

The eruption of the Hunga Tonga-Hunga Ha'apai submarine volcano in January 2022 was one of the most explosive volcanic events of the modern era, a new study has confirmed.

A research team realized magnetic reconnection driven by electron dynamics in laser-produced plasmas and measured the pure electron outflows. Their findings will be applied not only to space and astrophysical plasmas, but also to magnetic propulsion and fusion plasmas.

The recent Fagradalsfjall eruption in the southwest of Iceland has enthralled the whole world, including nature lovers and scientists alike. The eruption was especially important as it provided geologists with a unique opportunity to study magmas that were accumulated in a deep crustal magma reservoir but ultimately derived from the Earth's mantle (below 20 km).

Scientists say they have identified the exact mechanism responsible for the exceptional tsunami that spread quickly across the world after the colossal eruption of the Tonga volcano earlier this year.

Scientists have refined the use of magnetic fields to improve the performance of doughnut-shaped fusion facilities known as tokamaks. The improved technique protects internal parts from damage by instabilities and allows tokamaks to operate for longer without pausing.

A chemistry team has engineered a cobalt complex to act as a noninvasive chemical thermometer. They've done so by making the cobalt complex's nuclear spin ­-- a workhorse, fundamental magnetic property ­­-- mimic the agile, but less stable sensitivity of an electron's spin.

In the fall of 2017, a team of geologists had just set up a new volcanic forecasting modeling program on the Blue Waters and iForge supercomputers. Simultaneously, another team was monitoring activity at the Sierra Negra volcano in the Galapagos Islands, Ecuador. The teams shared their insights and what happened next was the fortuitous forecast of the June 2018 Sierra Negra eruption five months before it occurred.

Over nearly nine years, the Daya Bay Reactor Neutrino Experiment captured an unprecedented five and a half million interactions from subatomic particles called neutrinos. Now, the international team of physicists has reported the first result from the experiment's full dataset -- the most precise measurement yet of theta13, a key parameter for understanding how neutrinos change their 'flavor.' The result will help physicists explore some of the biggest mysteries surrounding the nature of matter and the universe.

Before its big burst in 2018, Kilauea spent ten years erupting more gently. Research gives new insights into the volcano's longstanding lava lake, one feature of this eruption.

Researchers have helped peer inside a nova -- a type of astrophysical nuclear explosion -- without leaving Earth. These stellar events help forge the universe's chemical elements, and astronomers have explored their nature with an intense isotope beam and a custom experimental device with record-setting sensitivity.
