…The discovery expands how motors and actuation systems can be designed. Most electromagnetic motors today depend on magnets and copper coils. This new approach can create motion without magnets or rare earth metals, which could be valuable in a world where material resources are limited.

The design could also be lighter and simpler. Since the rotating component can be made from resin instead of metal, devices may become lighter and faster to respond. That could help in robotics, compact machines, and precision systems.

Because the motor does not depend on magnetic fields, it may also work well in places where magnetic noise causes problems, including medical equipment and data storage devices…

Qcells has begun manufacturing solar cells at its new facility in Cartersville, Georgia, bringing the company closer to operating what it says is the United States’ first and only fully vertically integrated solar manufacturing factory.

The company announced that the plant is now producing solar cells and expects all production lines to reach full capacity by the third quarter of 2026. Once fully operational, the facility will manufacture ingots, wafers, cells, and solar modules under one roof.

The start of cell production marks a significant milestone for domestic solar manufacturing, as most solar panels installed in the US still rely on imported components. Qcells said the Cartersville site will become the largest operating solar cell factory in US history…

From the surface, Chetumal Bay looks almost placid – just a wide sheet of water with no hint of drama underneath. But below that calm is Taam ja’, a massive underwater sinkhole, or “blue hole,” that’s turned into an unexpected mystery for scientists.

At first, the plan seemed straightforward: map it with sonar, get a depth, move on. Instead, the early readings created a bigger problem – what if Taam ja’ isn’t anywhere near as shallow as those first numbers suggested?

The most recent measurements point to a hole that drops far deeper than expected, and the true bottom may still be out of reach…

…According to the standard cosmological model, small galaxies merge over time in a chaotic process to form larger ones, leaving behind swarms of faint dwarf galaxies that orbit massive host galaxies in an almost random arrangement…Instead of being randomly spread around their host galaxy, as the standard model of cosmology predicts, over 80% of these dwarf galaxies are concentrated on one side of the Andromeda galaxy…Specifically, all but one of Andromeda’s satellites lie within 107 degrees of the line pointing towards the Milky Way, a region covering only 64% of the host galaxy’s surroundings…“We have to look at more than three hundred simulated systems to find just one that is similarly extreme in its asymmetry as observed.” This makes Andromeda an extreme outlier, defying cosmological expectations.
