Nature uses 20 canonical amino acids as building blocks to make proteins, combining their sequences to create complex molecules that perform biological functions.

But what happens with the sequences not selected by nature? And what possibilities lie in constructing entirely new sequences to make novel (de novo) proteins bearing little resemblance to anything in nature?

While theories of holographic universes have been around since the 1990s, the latest study, published in the journal Physical Review Letters, contains the first proof, the researchers say.

To find the ‘evidence’, the researchers developed models of the holographic Universe that can be tested by peering back in time as far as 13 billion years, at the furthest reaches of the observable Universe. These models depend on the theory of quantum gravity, a theory that challenges the accepted version of classical gravity. The holographic principle says gravity comes from thin, vibrating strings which are all holograms of a flat, 2D Universe.

A quantum computer has been connected to Europe’s fastest supercomputer. It may be a step towards a new type of computing that combines traditional and quantum computers to quickly solve complex problems.

The promise of quantum computers is that they will eventually complete calculations that are impossible for the most powerful conventional computers. Though many researchers are working on perfecting quantum computers, many are also suggesting that existing, imperfect quantum computers could be more useful if connected to traditional supercomputers.

Christopher Nolan revealed to Total Film magazine that he recreated the first nuclear weapon detonation without CGI effects as part of the production for his new movie “Oppenehimer.” The film stars longtime Nolan collaborator Cillian Murphy as J. Robert Oppenheimer, a leading figure of the Manhattan Project and the creation the atomic bomb during World War II. Nolan has always favored practical effects over VFX (he even blew up a real Boeing 747 for “Tenet”), so it’s no surprise he went the practical route when it came time to film a nuclear weapon explosion.

“I think recreating the Trinity test [the first nuclear weapon detonation, in New Mexico] without the use of computer graphics was a huge challenge to take on,” Nolan said. “Andrew Jackson — my visual effects supervisor, I got him on board early on — was looking at how we could do a lot of the visual elements of the film practically, from representing quantum dynamics and quantum physics to the Trinity test itself, to recreating, with my team, Los Alamos up on a mesa in New Mexico in extraordinary weather, a lot of which was needed for the film, in terms of the very harsh conditions out there — there were huge practical challenges.”

Such a device could help address climate change and food scarcity, or break the Internet. Will the U.S. or China get there first?

A pair of microspheres can convert microwave signals over a wide frequency range into optical signals, which will be essential for future quantum technologies.

Future quantum communication systems will likely use microwaves to transfer information into and out of storage and processing devices but will use lasers to carry information from point to point within an extended network. Now researchers have demonstrated an improved method for converting microwaves to visible light signals by exploiting the way that electromagnetic waves can set up vibrations within microspheres [1]. Two microspheres in contact—one sensitive to microwaves and the other sensitive to optical signals—serve as the core of the converter. The work should give researchers a wider range of technological options as they develop advanced communications and computing networks.

Researchers are pursuing a variety of ways to store quantum information, or “qubits,” in microscopic, typically superconducting, structures. One common feature of such technologies is that reading or writing information relies on interactions with microwaves rather than on higher-frequency visible or infrared light from lasers. But lasers offer the best way to move information around, so extended networks of such devices will need ways to convert signals from one form to the other.

Following a visit to the UK’s National Quantum Technology Showcase, James McKenzie is excited about the prospects of UK firms developing “quantum 2.0” technology.

Black holes are known as the most terrifying, mysterious, and fascinating objects in the Universe. Eternally hungry, they eat everything in their path and are constantly expanding. But how small and how big can a black hole be? Unlike stars and planets, black holes have no size restrictions. They grow when they eat the matter around them. Does it mean that they can be not only super large but super small? Let’s find out!
