Tech companies have been funneling billions of dollars into quantum computers for years. The hope is that they’ll be a game changer for fields as diverse as finance, drug discovery, and logistics.

Those expectations have been especially high in physics and chemistry, where the weird effects of quantum mechanics come into play. In theory, this is where quantum computers could have a huge advantage over conventional machines.

But while the field struggles with the realities of tricky quantum hardware, another challenger is making headway in some of these most promising use cases. AI is now being applied to fundamental physics, chemistry, and materials science in a way that suggests quantum computing’s purported home turf might not be so safe after all.

The scale and complexity of quantum systems that can be simulated using AI is advancing rapidly, says Giuseppe Carleo, a professor of computational

It turns out that you don’t need to be a scientist to encode data in DNA. Researchers have been working on DNA-based data storage for decades, but a new template-based method inspired by our cells’ chemical processes is easy enough for even nonscientists to practice. The technique could pave the way for an unusual but ultra-stable way to store information. 

The idea of storing data in DNA was first proposed in the 1950s by the physicist Richard Feynman. Genetic material has exceptional storage density and durability; a single gram of DNA can store a trillion gigabytes of data and retain the information for thousands of years. Decades later, a team led by George Church at Harvard University put the idea into practice, encoding a 53,400-word book.

This early approach relied on DNA synthesis—stringing genetic sequences together piece by piece, like beads on a
