We like weird new engineering ideas here at Ars, and today we have a particularly interesting one in the realm of electric cars. It's called the Uni Wheel, and it has been designed by Hyundai and Kia as a way to revolutionize the layout of an EV powertrain to more efficiently use space. In fact, the automakers say it's not just for cars—the new drive system works with wheel sizes as small as four inches to as large as 25 inches.

For EV enthusiasts of a certain bent, there's something a little inefficient about the way virtually every EV powertrain is laid out.

Not the battery in the middle, though—while it's bulky and raises the overall height of EVs, it makes sense for weight distribution, although people working on structural carbon-fiber batteries have some different ideas about that. The problem is the EV drive unit, a bulky thing that contains the electric motor, some gearing, and usually some power electronics. These take up room between the axles and have to be packaged around.

The Centers for Disease Control and Prevention is warning everyone in the country to back away from pre-cut cantaloupe unless you're certain the fruit in question is not tied to a large, nationwide Salmonella outbreak that is unusually severe.

So far, 117 cases of infection across 34 states have been identified in the outbreak. The cases are in people ranging from infants to the elderly, including a 100-year-old. Of the cases, 61 (52 percent) have been hospitalized, and two deaths have been reported in Minnesota.

The CDC attributes the unusually high hospitalization rate to the fact that the pre-cut fruit was served at long-term care facilities and childcare centers. The elderly and young children are at higher risk of severe Salmonella illness.

A federal judge has stopped a US state’s landmark ban on TikTok from going into effect, in an important test case for the widespread political backlash that has grown in the country against the Chinese-owned video-sharing app.

Montana’s Senate Bill 419, which was signed by the state’s Republican governor, Greg Gianforte, in May, would have gone into effect in January and imposed a ban on downloads of the app.

On Thursday, Judge Donald Molloy granted TikTok’s request for a preliminary injunction after the ByteDance-owned app challenged the legislation in court, denouncing it as an unconstitutional infringement of its rights. Some users of the app also joined the legal challenge.
