CycleBoard Rover review: A strange yet exciting mashup of an electric scooter and a skateboard

The CycleBoard Rover is unlike anything I’ve tested before. It looks like a scooter and handles more like a skateboard. It’s a wild ride that is hard to describe, but that’s what I’m here to try and do.

Having tested plenty of electric scooters and e-skateboards before, I thought I could just hop on the CycleBoard Rover and blast away.

But I was woefully underestimating the learning curve here.

A treasure map for the realm of electrocatalysts

Efficient electrocatalysts, which are needed for the production of green hydrogen, for example, are hidden in materials composed of five or more elements. A team from Ruhr-Universität Bochum (RUB) and the University of Copenhagen has developed an efficient method for identifying promising candidates in the myriad of possible materials. To this end, the researchers combined experiments and simulation.

They published their report in the journal Advanced Energy Materials (“Unravelling Composition–Activity–Stability Trends in High Entropy Alloy Electrocatalysts by Using a Data-Guided Combinatorial Synthesis Strategy and Computational Modeling”).

Firefox browser goes down due to ‘infinite loop’ technical issue

The Firefox browser has stopped working due to a technical issue, with sites failing to load and no status information being provided to users.

The issue appears to be due to a HTTP3 problem. It appears that a recent update to the browser triggers an infinite loop in the network thread that prevents any pages from loading, leaving the browser useless.

However, this is an issue that can be temporarily overcome.

5 Epinutrients To Slow Down Aging, From A Naturopathic Doctor

What are epinutrients, you ask? Allow us to explain.


In a 2021 study, naturopathic doctor and functional medicine expert Kara Fitzgerald, N.D., author of Younger You, was able to improve participants’ biological age by three years. Sounds like a tall order, but the intervention was actually pretty simple: With a very doable diet and exercise plan, it only took eight weeks to see these results. “A big reason we actually made a difference in eight weeks’ time is because we very intentionally bathed the body in a high amount of epinutrients,” she says on this episode of the mindbodygreen podcast.

What are epinutrients, you ask? Allow Fitzgerald to explain below, along with a few of her favorites.

TSMC invests in new capacity despite forecasts chip demand will ease

Last year, Germany spent $53 billion on defense. This year, TSMC is spending $44 billion on chip factories. (In 2019, TSMC only spent $14.9 billion, so they are spending insane amounts of money trying to fix the chip shortage.) Pretty much everyone in the chip business is also dramatically increasing their spending as well.


TSMC investment will “put a ceiling” on Samsung, Intel’s foundry plans.
