In 1958, Ford showed the world a car like it had never seen before, one powered by a small nuclear reactor. The Ford Nucleon, as it was christened, was envisioned as a car capable of driving more than 5000 miles between fueling stops, appealing to a postwar fixation with convenience that has dominated American consumerism since. Like some other midcentury nuclear fantasies, though, the Nucleon never came to fruition, in part due to engineering problems we still struggle with to this day.

Before we examine why the Nucleon could never be, let’s get a better grasp of the car itself, starting with its utterly comical dimensions. Ford’s press materials envisaged the Nucleon stretching 200.3 inches long and 77.4 wide, making it as long as the new Ford Maverick compact pickup, but slightly wider. Its roof was said to measure just 41.4 inches high, making it less than an inch taller than the legendarily low-slung Ford GT40.

The ascendant industry is headlined by Beyond Meat and Impossible Foods, whose alt-meat burgers, chicken and sausage products have disrupted the $733 billion U.S. food manufacturing industry. That has prompted Tyson Foods, Purdue, Hormel, Cargill and other traditional meat producers to launch their own products in the category.

As consumers become increasingly comfortable eating faux-meat burgers that look, cook and taste like the real thing, a food-tech start-up backed by Jeff Bezos and Bill Gates is using fungus as the primary ingredient to create alt-meat foods.

Nature’s Fynd, based in Chicago, has raised $158 million in funding from investors including Bezos, Gates, and Al Gore. The company’s meatless breakfast patties and hamburgers, dairy-free cream cheese and yogurt, and chicken-less nuggets are scheduled to hit grocers’ shelves later this year.

A new class of drugs prevents the repair of damaged DNA. In recent animal studies, scientists found that it killed cancer cells with BRCA mutations.

Imagine you sit down and pick up your favorite book. You look at the image on the front cover, run your fingers across the smooth book sleeve, and smell that familiar book smell as you flick through the pages. To you, the book is made up of a range of sensory appearances.

But you also expect the book has its own independent existence behind those appearances. So when you put the book down on the coffee table and walk into the kitchen, or leave your house to go to work, you expect the book still looks, feels, and smells just as it did when you were holding it.

Two important factors limiting Moore’s Law are power consumption and Coulomb interactions are interactions between electric charges that follow Coloumb’s law, an electrodynamics theory.

These interactions can be a major challenge for the development of nanoelectronic circuits. Quantum spin Hall (QSH) insulators are particularly promising materials for the development of low-power electronics, yet so far the impact of Coulomb interactions on nanocircuits made by these materials have only been examined theoretically, rather than experimentally.

Researchers at Nanjing University and Peking University have recently observed one-dimensional (1D) Coulomb drag between adjacent QSH edges separated by an air gap. Their paper, published in Nature Electronics, highlights the potential of QSH effects for suppressing the adverse effects of Coulomb interactions on the performance of nanocircuits.

A revolutionary new class of amphibious vehicle will transform the search for lost vessels on the ocean floor, says marine archaeologist Dr Robert Ballard.

“Because nothing can protect hardware, software, applications or data from a quantum-enabled adversary, encryption keys and data will require re-encrypting with a quantum-resistant algorithm and deleting or physically securing copies and backups.” v/@preskil… See More.

To ease the disruption caused by moving away from quantum-vulnerable cryptographic code, NIST has released a draft document describing the first steps of that journey.

Can we end world hunger by 2030? Thanks to a new program, the data for it is all there.

Researchers have demonstrated how to keep a network of nanowires in a state that’s right on what’s known as the edge of chaos – an achievement that could be used to produce artificial intelligence (AI) that acts much like the human brain does.

The team used varying levels of electricity on a nanowire simulation, finding a balance when the electric signal was too low when the signal was too high. If the signal was too low, the network’s outputs weren’t complex enough to be useful; if the signal was too high, the outputs were a mess and also useless.

“We found that if you push the signal too slowly the network just does the same thing over and over without learning and developing. If we pushed it too hard and fast, the network becomes erratic and unpredictable,” says physicist Joel Hochstetter from the University of Sydney and the study’s lead author.
