Stressed Ice Generates Electricity, Researchers Find

gizmodo.com Gayoung Lee 2025-10-16 22:50:33

Don’t mess with ice. When it’s stressed, ice can get seriously sparky. Scientists have discovered that ordinary ice—the same substance found in iced coffee or the frosty sprinkle on mountaintops—is imbued with remarkable electromechanical properties. Ice is flexoelectric, so when it’s bent, stretched, or twisted, it can generate electricity, according to a Nature Physics paper published August 27. What’s more, ice’s peculiar electric properties appear to change with temperature, leading researc

Scientists Pinpoint Cause of Mysterious Electrical Surges on Satellites

gizmodo.com Passant Rabie 2025-10-17 02:40:43

In 1994, two Canadian TV satellites failed within mere hours of each other. The pair was in a geostationary orbit when a major solar storm hit, resulting in electrostatic discharges that disabled their control electronics. Anik E1 and E2 are just one example of the effects of electric charge buildup on satellites, known as spacecraft environment discharge. New findings show a direct correlation between a spacecraft’s electric discharge and peaks in the flux of electrons in space, identifying hu

Porsche’s next Cayenne is fully electric—we drove the prototype

Porsche provided flights from Albany to Barcelona and accommodation so Ars could drive a prototype Cayenne Electric. Ars does not accept paid editorial content. Curved displays in cars are increasingly common, adding a bit of shape to the increasing pixel overload we face behind the steering wheel.

Ride1Up TrailRush Electric Mountain Bike Review: Quality Components, Bargain Price

Buying a direct-to-consumer bike can be almost as big a gamble as investing in cryptocurrency. While a customer is not likely to lose their shirt investing in a new electric bike, buying a poorly made one may result in a serious crash or catch the garage on fire. For these reasons and more, it’s wise to do some research before clicking on the Add to Cart button. The highest-end legacy-brand e-MTBs retail for upwards of $14,000.

What Is the Magnetic Constant, and Why Does It Matter?

This means these three values can’t be independent; if you know two of them, you can derive the third. How do physicists deal with this? We define the speed of light as exactly 299,792,458 meters per second. (How do we know it’s exact? Because we define a meter as the distance light travels in 1/299,792,458 of a second.) Then we measure the magnetic constant (μ 0 ) and use that value along with the speed of light to calculate the electric constant (ε 0 ). Maybe that seems like cheating, but to

What Is the Electric Constant and Why Should You Care?

It's fun to think about the fundamental physical constants. These are special values used in our models of the physical universe. They include things like the speed of light, the gravitational constant, and Planck’s constant, and they’re “fundamental” in the sense that we can't derive them theoretically, we can only measure them. We use these in solving physics problems all the time, so it’s easy to take them for granted. But why are there such numbers in nature, and why do they just happen to

Polestar sets production car record for longest drive on a single charge

Ars recently reviewed the Polestar 3, the large electric SUV from the performance-oriented Volvo spinoff. There is a lot to like about the big Polestar, particularly the way it drives: sharp enough to give Porsche cause for concern. Among the handful of things I wasn't so keen on was its reluctance to drive slowly. Like a racehorse champing at the bit, the twin-motor Polestar 3 wanted to deliver lots of power with not much pedal travel, and it took a while, and some conscious effort, to adapt.
