The most recent email you sent was likely encrypted using a tried-and-true method that relies on the idea that even the fastest computer would be unable to efficiently break a gigantic number into factors.

Quantum computers, on the other hand, promise to rapidly crack complex cryptographic systems that a classical computer might never be able to unravel. This promise is based on a quantum factoring algorithm proposed in 1994 by Peter Shor, who is now a professor at MIT.

But while researchers have taken great strides in the last 30 years, scientists have yet to build a quantum computer powerful enough to run Shor’s algorithm.

Scientists at PPPL have developed innovative solutions to manage the intense heat generated within fusion reactors.

Scientists from the University of Reading developed a hydrogel that learns to play ‘Pong’ and mimics heartbeats in sync with a pacemaker. The study suggests hydrogels can exhibit adaptive behaviors.

A molecular biology research team at the University of Miami Miller School of Medicine has become the first to map out how mitochondrial messenger RNA folds in human cells.

The research advances knowledge about the expression of genes in the mitochondria and paves the way for identification of therapeutic targets for mitochondrial neurodegenerative diseases.

“Dysfunctional mitochondria can cause devastating diseases, frequently with childhood-onset, known as mitochondrial encephalomyopathies. Despite advances in identifying genes responsible for these disorders, their pathophysiological mechanisms have been poorly understood,” said Antoni Barrientos, Ph.D., professor of neurology and biochemistry and molecular biology at the Miller School. “This was partly due to a lack of a full understanding of mitochondrial gene expression. Specifically, nothing was known about how mitochondrial messenger RNA folds and how that could influence its stability and translation in health and disease.”

To produce light, lasers typically rely on optical cavities, pairs of mirrors facing each other that amplify light by bouncing it back and forth. Recently, some physicists have been investigating the generation of “laser light” in open air without the use of optical cavities, a phenomenon known as cavity-free lasing in atmospheric air.

SpaceX finished construction of its second launch tower down at Starbase, Texas for its Starship rocket. This comes hopefully a few weeks out from the next launch of the company’s next generation rocket.

Over the last few months SpaceX has cleared land and constructed a new launch tower at its research, development, and launch facilities down at Starbase, Texas. This now gives the company three towers total for Starship, two at Starbase and one more over in Florida at LC-39A.

There is still plenty of work to be done at the pad, it still needs the launch table, chopsticks, plumbing for propellent, etc. However, the biggest and most prominent feature is now complete.

I’ll never not see Neuralink as some kind of sorcery.

The next step, says Esat, is to increase the new device’s magnetic field sensitivity by implementing more advanced sensing protocols based on pulsed electron spin resonance schemes and by finding molecules with longer spin decoherence times. “We hope to increase the sensitivity by a factor of about 1,000, which would allow us to detect nuclear spins at the atomic scale,” he says.

A holy grail for quantum sensing

The new atomic-scale quantum magnetic field sensor should also make it possible to resolve spins in certain emerging two-dimensional quantum materials. These materials are predicted to have many complex magnetic orders, but they cannot be measured with existing instruments, Heinrich and his QNS colleague Yujeong Bae note. Another possibility would be to use the sensor to study so-called encapsulated spin systems such as endohedral-fullerenes, which comprise a magnetic core surrounded by an inert carbon cage.
