Physicists at the National Ignition Facility are learning how to better control crushingly violent “shots”.

One of the most fascinating implications of Einstein’s famous equation E=mc2 is that matter and energy are interchangeable.
PCs are no longer the massive beige boxes that sit on your desk taking up a massive amount of working real estate. Thanks to modernization and miniaturization, PCs can now fit into a tiny box.
How tiny?
Well, a hockey puck is 3 inches in diameter and an inch thick, which is not a lot bigger than the Blackview MP80.
Need a powerful Windows 11 PC that’s not much bigger than a hockey puck and won’t cost you much? Then the Blackview MP80 is the mini PC for you.
The surprising detection of light 200 times more powerful than previous observations from the nearby pulsar Vela indicates hidden physics around dead stars.
Their advantages extend beyond reducing carbon emissions.
Thirteen US states are now implementing underground thermal energy networks to reduce buildings’ carbon emissions as part of a nationwide push to adopt cleaner energy sources.
Thermal energy networks use pipe loops that connect multiple buildings and provide heating and cooling through water-source heat pumps. Geothermal heat is commonly used in these networks, but it is also possible to bring in waste heat from other buildings through the sewer system.
The latest research on quantum materials and electron curves could revamp our energy-efficient electronics.
As current courses through a battery, its materials erode over time. Mechanical influences such as stress and strain affect this trajectory, although their impacts on battery efficacy and longevity are not fully understood.
A team led by researchers at the Department of Energy’s Oak Ridge National Laboratory developed a framework for designing solid-state batteries, or SSBs, with mechanics in mind. Their paper, published in Science, reviewed how these factors change SSBs during their cycling.
“Our goal is to highlight the importance of mechanics in battery performance,” said Sergiy Kalnaus, a scientist in ORNL’s Multiphysics Modeling and Flows group. “A lot of studies have focused on chemical or electric properties but have neglected to show the underlying mechanics.”
We often wonder where we might find a truly sustainable and abundant source of energy, and the answer might turn out to be in the emptiness all around us.

The group led by researchers from the Technical University of Denmark employed a technique using an X-ray microscope that could see acoustic waves within mm-sized crystals with subpicosecond precision. This enabled the team to see how mechanical energy thermalizes across timeframes ranging from picoseconds to microseconds by directly visiting the creation, propagation, branching, and energy dissipation of longitudinal and transverse acoustic waves in a diamond.
The world’s first artificial energy island has secured its environmental permit, so it’s now all systems go in Belgium.
Princess Elisabeth Island is a pioneering electricity grid at sea that’s going to connect offshore wind farms to the Belgian mainland and also serve as a hub for future interconnectors with the UK and Denmark.
Belgian electricity transmission system operator Elia is the project’s developer, and obtaining the permit, which Elia applied for in January 2023, is a key milestone. Construction will take over two years, from March 2024 to August 2026.
