Inexpensive battery charges rapidly for electric vehicles, reduces range anxiety — ScienceDaily
Range anxiety, the fear of running out of power before being able to recharge an electric vehicle, may be a thing of the past, according to a team of Penn State engineers who are looking at lithium iron phosphate batteries that have a range of 250 miles with the ability to charge in 10 minutes. […]
Electric eels can supercharge their attacks by working together
Stunning new video footage captures electric eels in the Amazon hunting in groups of more than 100. Deadly packs then splinter off to collectively deliver a supercharged jolt that blasts fish out of the water, a new study finds. This is the first time such group hunting has been seen in Volta’s electric eels (Electrophorus […]
Some electric eels coordinate attacks to zap their prey
One Volta’s electric eel — able to subdue small fish with an 860-volt jolt — is scary enough. Now imagine over 100 eels swirling about, unleashing coordinated electric attacks. Such a sight was assumed to be only the stuff of nightmares, at least for prey. Researchers have long thought that these eels, a type of […]
What to know before you buy an electric vehicle
Understanding the different charging levels and types will help you make a more informed decision about EV ownership. (Photo by CHUTTERSNAP on Unsplash/) Electric cars have long remained objects of fantasy, tantalizingly just out of reach for drivers who imagine the joy of whooshing silently around town, powered by electrons that were hopefully produced by […]
New curriculum improves students’ understanding of electric circuits in schools
FRANKFURT / TÜBINGEN. Life without electricity is something that is no longer imaginable. Whether it be a smartphone, hair-dryer or a ceiling lamp – the technical accomplishments we hold dear all require electricity. Although every child at school learns that electricity can only flow in a closed electric circuit, what is actually the difference between […]

First ride: Harley’s stylish new electric bicycles
One of Serial 1’s Rush/Cty e-bikes. (Rob Verger /) On a recent misty day in Manhattan, I hit 26 miles per hour or so on one of Harley-Davidson’s new e-bikes. I was on a bike trail on the west side of the island, a stretch of path that was either flat or slightly downhill. I […]
Electric ‘knob’ tunes chemical reaction rates in quantum gas — ScienceDaily
Building on their newfound ability to induce molecules in ultracold gases to interact with each other over long distances, JILA researchers have used an electric “knob” to influence molecular collisions and dramatically raise or lower chemical reaction rates. These super-chilly gases follow the seemingly counterintuitive rules of quantum mechanics, featuring exact units, or quanta, of […]
I rode an electric motorcycle for the first time. Here’s what I learned.
The Zero FX is a dual-sport motorcycle that’s well-suited for a city. (Roselle Chen /) The Zero FX electric motorcycle is an exciting machine with a top speed of 85 miles per hour and enough acceleration to frighten yourself if you twist aggressively enough on the throttle. But as a relative beginner to the motorcycle […]
